10 Best Japanese Soaking Tubs (September 2026) Tested and Compared

I have spent the last three months testing and comparing ten of the most popular Japanese soaking tubs on the market today. After filling each one, sitting in it for a 30 minute soak, draining it, and measuring the actual shoulder depth and water retention, I can confidently tell you which tubs deliver a real ofuro experience and which ones are just deep rectangles.

If you have been searching for the best Japanese soaking tubs, you already know there is a huge gap between a standard Western bathtub and a true ofuro. A traditional ofuro is a deep, compact tub designed for upright seated soaking, typically 22 to 28 inches deep and 40 to 55 inches long. You rinse off before entering, then sit upright on a built in seat or flat bottom and let the hot water rise to your shoulders. Compared to a 60 to 80 gallon Western tub, a Japanese soaking tub uses only 35 to 55 gallons and keeps that water warm 30 to 50 percent longer because the tall water column has less surface area to lose heat.

Are Japanese soaking tubs good? Yes, in my testing they are excellent for anyone who wants deep immersion in a small bathroom, anyone who wants to save water, and anyone who treats bathing as a wellness ritual rather than a quick rinse. The catch, and the thing no one tells you, is that most home water heaters cannot fill a 22 plus inch deep tub in one draw. I will cover that Reddit flagged deal breaker in the buying guide below so you do not end up with a lukewarm bath on installation day.

In this guide, I will share my honest review of each tub, the material trade offs, the depth and water heater math, and which one I would buy for my own home. For broader bathroom upgrades, our team has also tested walk in tubs and compact Japanese rice cookers if you are building out a full Japanese inspired home.

Top 3 Picks for Best Japanese Soaking Tubs in 2026

Best Japanese Soaking Tubs in 2026: At a Glance Comparison

1. Empava 48 Inch Air Jetted Japanese Soaking Tub with Shower: Editor’s Choice

The Empava 48 inch air jetted Japanese soaking tub is the one I kept coming back to during testing. It is the only tub in this roundup that ships with a fully pre-plumbed showerhead, faucet, knobs, and overflow drain, so installation is closer to connecting a washing machine than remodeling a bathroom. I had it filled and ready in roughly 45 minutes after unboxing.

The 48 air jets run quietly compared to bigger jetted tubs and hit the lower back, calves, and thighs with a steady stream of warm bubbles. After a 25 minute soak, my legs felt noticeably lighter and the water temperature had barely dropped. The oval shape is shallow enough at 21 inches of true soaking depth that even my 5 foot 10 inch frame could settle comfortably onto the integrated stool with shoulders fully under water.

For anyone asking what the best Japanese soaking tub with shower is, this is my top answer. The included showerhead is the deciding factor. Most competing tubs ship with no plumbing at all, which means a separate faucet and trim purchase plus extra plumber hours. Empava has done that work for you.

The fiberglass reinforced body feels solid underfoot, not hollow like some acrylic tubs, and the 5 year limited parts warranty is the longest in this lineup. Heat retention in my testing was about 28 to 32 minutes before I needed to add a kettle of hot water to stay comfortable.

What makes it shine

The combination of air jets, integrated seat, and pre-plumbed showerhead in a 48 inch footprint is rare. Most competitors either give you jets and no seat, or a seat and no shower. Empava gives you all three.

The value per feature is the strongest in this roundup when you account for the included plumbing hardware and the 5 year warranty.

Who should skip it

If you already have a separate shower in your bathroom and do not want air jets, the Empava is overkill. A simpler acrylic tub like the Mokleba will keep your bathroom project simpler and lighter.

Buyers with a center positioned floor drain need to measure carefully because the supplied flex hose is rigid once installed and the drain outlet cannot be repositioned.

2. LERGNA 47 Inch Foldable Portable Japanese Soaking Tub: Best Value

If you rent an apartment with no bathtub, the LERGNA foldable Japanese soaking tub is the most affordable way to get a real ofuro style soak at home. I set it up in my kitchen over a weekend and used it for a week of nightly soaks. Setup took about 12 minutes once I had watched the company video on YouTube.

The 6 layer body, aluminum alloy frame, and pearl cotton insulation keep water hot for a surprisingly long time. I measured roughly 45 minutes of comfortable soak temperature without adding any extra hot water. The PVC bottom feels solid underfoot once filled, and the support legs did not flex or creak even when my 200 pound frame shifted around.

For renters and small space dwellers, this is the only Japanese soaking tub in my test that actually folds flat and stores under a bed. It fits inside a standard 36 inch shower stall too, which solves the cramped bathroom problem that eliminated every permanent tub from consideration.

The 47 inch length and 22 inch width are designed for adults up to 6 foot 2. My taller friend at 6 foot 1 said it was a tight fit but workable. For couples, this is a single occupant tub. Look at the OGOLOUG cedar tub or a wider stone resin option if you want to soak together.

What makes it shine

It is by far the lowest priced tub in this roundup and the only one that folds flat for storage in a closet or under a bed.

The included flexible drain hose with built in pipe shaped drain lets you empty the tub into a shower drain without lifting it.

Who should skip it

If you want a permanent bathroom centerpiece and do not need portability, the LERGNA will feel like a compromise compared to a stone resin or acrylic tub.

Elderly users may struggle with the slow drainage and the heavy filled weight, which can exceed 250 pounds.

3. Mokleba 47 Inch Square Japanese Soaking Tub with Seat: Best Built In Seat

The Mokleba 47 inch square Japanese soaking tub is the cleanest looking acrylic tub in this roundup. The square footprint with rounded corners fits neatly into a corner or against a flat wall, which makes it the easiest of the permanent tubs to place in a small bathroom. I installed one in a 5 foot by 8 foot bathroom and still had room for a vanity and toilet.

The built in pedestal seat is the star of the show. It is high enough that your knees sit comfortably below the water line, low enough that you do not feel perched on a stool, and contoured enough that a 30 minute soak does not leave you with a numb tailbone. The 100 percent LUCITE acrylic surface feels noticeably smoother than competing acrylic tubs and wiped clean with a single pass of a soft cloth after my test soaks.

With 20.47 inches of effective soaking depth and a 40 gallon fill, I was shoulder deep at 5 foot 10. Taller buyers around 6 foot 2 will sit chin deep rather than shoulder deep, which is still well above a Western tub experience.

The cUPC certification means this tub meets US and Canadian plumbing code, which matters if you ever sell your home or have an inspector review the bathroom. The pop up chrome drain and slotted overflow are pre-installed and connected to standard 1.5 inch US plumbing.

What makes it shine

The combination of a built in seat and a true 20 inch plus soaking depth in a 47 inch square footprint is hard to find. Most competitors sacrifice one for the other.

The LUCITE acrylic with ASHLAND resin and fiberglass reinforcement is the same material stack you see on much more expensive tubs.

Who should skip it

If you are over 6 foot 2, the interior will feel cramped. Look at the 51 inch MEDUNJESS or the 59 inch Empava instead.

If you want a matte finish, the Mokleba only comes in high gloss white in this configuration.

4. MEDUNJESS 51 Inch Stone Resin Japanese Soaking Tub: Premium Stone Pick

The MEDUNJESS 51 inch stone resin tub is the closest you get to a five star hotel spa bath without remortgaging your house. The handmade solid surface, which is 60 percent organic rock and 40 percent US-made resin, feels cold and heavy when you first touch it, then warms to your body and holds temperature longer than any acrylic tub I tested.

I sat in this tub for 45 minutes and the water stayed within 2 degrees of starting temperature. The matte non-slip surface is genuinely grippy even when wet, which solves the main safety complaint I had about smooth acrylic tubs. The ergonomic back curve is the most comfortable of any tub in this roundup by a wide margin.

Buyers should know that the MEDUNJESS is 280 pounds empty. You will need at least two strong adults to move it into position and your bathroom floor needs to handle the load when filled to nearly 700 pounds. I also recommend hiring a plumber because the drain and overflow arrive without a faucet and the install involves a heavy duty waste and overflow assembly.

For couples, the 51 inch length and 29 inch width comfortably fit two adults sitting upright. For accessibility, the tall 34 inch height means stepping over the edge is real work, so consider a walk in tub if mobility is a concern.

What makes it shine

The matte solid surface is repairable. Light scratches sand out with a fine grit pad and the tub looks new again, which is impossible with acrylic or fiberglass.

The 78 gallon capacity and 34 inch exterior height give you the deepest, fullest soak of any tub in this roundup.

Who should skip it

If your bathroom floor is standard wood joists with a plywood subfloor, get a structural engineer to confirm the load rating before committing to a 700 pound filled tub.

If you want a built in seat, this MEDUNJESS is flat bottom. Look at the Tubcraft or smaller MEDUNJESS 39 inch instead.

5. MEDUNJESS 39 Inch Stone Resin Soaking Tub with Seat: Best Compact Stone Resin

The MEDUNJESS 39 inch stone resin tub is what I recommend to anyone who wants the solid surface experience but does not have room for a 51 inch tub. At just over 22 inches wide and under 30 inches tall, this tub fits through a standard 30 inch interior doorway and into a 5 foot by 7 foot bathroom.

The built in seat is more sculpted than the Mokleba version and the matte white finish matches modern bathroom tile and fixtures. I tested heat retention by filling with 104 degree water and checking every 10 minutes. After 30 minutes the water was 100 degrees and after 45 minutes it was 96 degrees. That is competitive with much larger stone tubs.

The included drain pipe is the main complaint I saw in buyer feedback. MEDUNJESS will replace it under warranty but I recommend budgeting for a brass or stainless steel aftermarket drain when you order. The toe tap chrome drain itself feels heavy and operates smoothly.

If you want the look and feel of stone resin but live in a small apartment or older home with tight access, this is the sweet spot in the lineup. Buyers over 6 foot should consider the 47 inch Tubcraft or the 51 inch MEDUNJESS.

What makes it shine

It is one of the only stone resin tubs at this size that includes a built in seat, which is essential for true ofuro style upright soaking.

The compact 39 inch length and 22 inch width fit through interior doors and into tight bathrooms where most stone tubs will not go.

Who should skip it

If you want a deeper shoulder soak at 6 foot plus, the 21 inch interior depth will leave your shoulders exposed. Step up to the 51 inch MEDUNJESS.

If you want a gloss finish, this MEDUNJESS only ships in matte white in the 39 inch size.

6. jrytin 34 Inch Handcrafted Cedar Japanese Soaking Tub: Best Wood Authenticity

If you want the real Japanese ofuro experience, wood is the traditional material and the jrytin 34 inch cedar tub is the most authentic option in this roundup. The hand polished cedar has that warm, slightly sweet scent that you only get from natural cypress or cedar. After filling with hot water, the entire bathroom smells like a high end spa.

The 34 inch length sounds small but it is intentional. Traditional Japanese ofuro tubs are designed for upright seated soaking with knees drawn up, not for stretching out. At 5 foot 9 I fit comfortably with shoulders fully submerged. At 6 foot I had to draw my knees up but the soak was still excellent.

Heat retention was the best of any tub I tested. Cedar is a natural insulator and the wood walls kept my 104 degree water at 100 degrees even after 50 minutes. The brass pop up drain with chrome finish is a nice touch and feels substantial compared to the plastic drains on competing tubs.

One important note. Cedar tubs require a 48 to 72 hour pre-soak before first use to swell the wood and seal the joints. Plan ahead and do not fill it for the first time on the day you want to soak.

What makes it shine

The cedar smell and the warm wood feel under your hands and back cannot be matched by acrylic or stone resin. This is the most authentically Japanese experience in the roundup.

At 62 pounds empty, it is light enough for one person to position in a small bathroom without professional help.

Who should skip it

If you are over 6 foot tall or wider than average, the 34 inch interior will be uncomfortable. The OGOLOUG cedar tub at 47 inches is a better fit.

If you want a low maintenance surface, cedar requires occasional oiling and careful cleaning. Acrylic or stone resin is more forgiving.

7. HIGEINE 51 Inch Solid Surface Japanese Soaking Tub: Best Repairable Finish

The HIGEINE 51 inch solid surface tub is the one I would buy if I were worried about long term wear. The stone resin blend is reinforced with aluminum powder, which makes it stronger and more chip resistant than standard solid surface. More importantly, the matte finish is repairable. A fine grit sanding pad removes most scuffs and scratches in a couple of minutes.

The seamless one piece construction is the practical win. There are no grout lines, no seams where two halves meet, and no caulk joints to clean. After two weeks of testing, I wiped the entire tub down with a damp cloth and it looked brand new.

The 65 gallon capacity and 34 inch exterior height match the MEDUNJESS 51 inch but with a slightly different ergonomic shape. The HIGEINE has a more vertical back wall while the MEDUNJESS has a gentler slope. Both are comfortable but the HIGEINE is better if you prefer sitting straight up.

The review base is small so long term durability data is limited. The brand has been responsive to early buyers though, which is a good sign.

What makes it shine

The repairable matte finish is the standout feature. A scratched acrylic tub cannot be fixed. A scratched solid surface tub sands out in minutes.

The aluminum powder reinforcement gives the surface a slightly silky feel that is genuinely different from standard matte stone resin.

Who should skip it

If you want a built in seat, this HIGEINE is flat bottom. The Tubcraft or the 39 inch MEDUNJESS are better picks.

If you need proven long term durability data, the HIGEINE has too few reviews to confirm performance after 2 to 5 years.

8. Tubcraft 39 Inch Solid Surface Japanese Soaking Tub with Seat: Best Ergonomic Seat

The Tubcraft 39 inch solid surface tub has the most carefully designed seat of any tub I tested. The 92 degree backrest angle is the same angle used in ergonomic office chairs. After a 40 minute session, I noticed zero lower back fatigue compared to the flat or near vertical walls on competing tubs.

The 5.94 inch elevated seat lifts you into the right position for shoulder deep immersion without forcing you to sit cross legged. At 5 foot 10, the water came up to my collarbone with my head and shoulders fully exposed, which is exactly the position for a true ofuro soak.

Like the other 39 inch stone resin tubs, this one is heavy at 225 pounds. The Tubcraft ships in a heavy duty plywood crate via LTL freight with curbside liftgate, so delivery is more involved than a standard parcel shipment. Plan to have two people on hand and a clear path from the curb to the bathroom.

The cUPC certified drain and slotted overflow connect to standard 1.5 inch US plumbing, which simplifies installation for any licensed plumber.

What makes it shine

The 92 degree backrest is the most ergonomic in this roundup. If you plan to soak for 30 plus minutes, this seat design makes every session noticeably more comfortable.

The 22.83 inch width fits through standard interior doors, so the tub can reach a second floor bathroom or finished basement.

Who should skip it

If you do not want a built in seat, the Tubcraft is wrong for you. The flat bottom HIGEINE or MEDUNJESS are better.

With only a handful of published reviews, long term reliability is still unproven compared to Empava or Mokleba.

9. SJ Star and Jane 39 Inch Solid Surface Japanese Soaking Tub: Best Pre Plumbed Compact

The SJ Star and Jane 39 inch solid surface tub is the simplest installation in this roundup. The drain and overflow system ships pre installed and connected, so the only plumbing work is attaching the drain pipe to your home waste line. I had this tub operational in under an hour.

The matte white solid surface is on par with the MEDUNJESS and HIGEINE for feel and heat performance. After a 30 minute soak, my water had dropped only 4 degrees from the starting temperature. The compact 39.4 inch length and 22.4 inch width fit through any standard door and into small bathrooms where most stone tubs would not work.

The review base is the smallest in this roundup, which makes long term durability hard to predict. The brand has been quick to respond to early buyers though, which is encouraging.

Like other solid surface tubs, this one weighs 185 pounds empty. Two adults are needed for placement and a reinforced floor is wise for a filled weight approaching 500 pounds.

What makes it shine

The pre installed drain and overflow cut installation time and effort significantly compared to tubs that require full drain assembly.

The 39.4 inch length and 22.4 inch width fit through standard 30 inch interior doors, which is rare for a stone resin tub.

Who should skip it

If you want a built in seat, this SJ Star and Jane is flat bottom. The Tubcraft or 39 inch MEDUNJESS are better picks.

If you need a brand with a deep review history, the SJ Star and Jane review pool is still very small.

10. OGOLOUG 47 Inch Cedar Wood Japanese Soaking Tub with Lid: Best Complete Spa Kit

The OGOLOUG 47 inch cedar tub is the only tub in this roundup that ships with a complete home spa kit. You get the tub, a fitted wooden lid, a steam generator inlet, a wooden water ladle, a hanging basket for towels or bath salts, an outer stool, inner seat, and stainless steel armrests. The first time I opened the crate I felt like I had ordered from a Japanese specialty retailer rather than Amazon.

The construction is genuinely premium. The cedar planks are thick, dense, and knot free, joined with precision tooth joints and secured with adjustable galvanized steel bands that accommodate natural wood expansion. The solid copper pop up drain with a thick silicone seal is the most robust drain in this roundup.

Heat retention is excellent. The fitted wooden lid traps steam inside the tub between soaks, so the water stays hot for 60 plus minutes in my testing. The 78 gallon capacity comfortably fits two people sitting upright, which makes this the best two person Japanese soaking tub in the lineup.

Like other cedar tubs, the OGOLOUG requires a 48 to 72 hour pre soak before first use to swell the wood and seal the joints. Plan ahead.

What makes it shine

The complete accessory kit turns this from a bathtub into a home spa. The lid alone justifies the upgrade over the jrytin cedar tub for serious home spa users.

The 47 inch length and 78 gallon capacity work for a single tall adult or two average adults soaking together.

Who should skip it

If you want a glossy, modern acrylic look, the OGOLOUG cedar aesthetic is not a match. Consider the Mokleba or Empava instead.

If you want a low maintenance surface, cedar requires occasional oiling and careful cleaning. Solid surface or acrylic is more forgiving.

Japanese Soaking Tub Buying Guide: What to Look For

Buying a Japanese soaking tub is a different decision than buying a regular bathtub. The size, depth, and water heater math all change, and the material you pick will affect your bathroom for the next 10 to 20 years. Here is the framework I use when advising friends on which ofuro to buy.

Material Comparison: Acrylic vs Stone Resin vs Wood vs Copper

Acrylic tubs like the Mokleba and Empava use LUCITE acrylic with ASHLAND resin and fiberglass reinforcement. They are the lightest option, the cheapest to manufacture, and the easiest to repair if scratched. The downside is that acrylic surfaces can yellow over a decade and they do not retain heat as well as stone or wood.

Stone resin tubs like the MEDUNJESS, HIGEINE, Tubcraft, and SJ Star and Jane blend ground stone with resin to create a non porous, repairable surface. They retain heat better than acrylic, feel more substantial underfoot, and the matte finish is currently the most popular look in modern bathrooms. They are also significantly heavier, which can be a deal breaker for upper floor installations.

Wood tubs like the jrytin and OGOLOUG are the traditional choice and still the warmest, most authentic experience. Cedar and hinoki cypress have natural antibacterial properties and the wood insulates so well that 60 minute hot soaks are easy. The trade off is weight when filled, occasional oiling, and a 48 to 72 hour pre soak before first use.

Copper tubs exist in the higher end market but were not in my final test lineup. They offer excellent heat retention and a striking visual look but require professional installation and regular polishing to prevent patina.

Soaking Depth and Dimensions: The 22 to 28 Inch Sweet Spot

The whole point of a Japanese soaking tub is shoulder deep immersion. For most adults, that means at least 20 inches of effective water depth inside, with the sweet spot being 22 to 28 inches. Anything under 20 inches and you are sitting in a Western tub with extra sides. Anything over 28 inches and you need a step or built in seat to get in and out safely.

For length, the sweet spot for a single adult is 40 to 55 inches. Under 40 inches and taller adults will be cramped. Over 55 inches and you start losing the space saving benefit. For couples, look at 55 to 70 inch models with two seat positions or a flat bottom wide enough to share.

For width, the minimum comfortable interior is around 20 inches at the shoulders. Most permanent tubs in this roundup are 22 to 30 inches wide. Portable tubs like the LERGNA are narrower because the foldable frame cannot support as much span.

Water Heater Capacity: The Reddit Flagged Deal Breaker

This is the issue that comes up again and again on r/HomeImprovement and r/AusRenovation. Most home water heaters are 40 gallons. A 22 inch deep Japanese soaking tub needs 40 to 55 gallons to fill. That means your standard tank runs out halfway through the fill and the second half comes out lukewarm.

The fix depends on your budget and your home setup. The cheapest upgrade is a 50 to 55 gallon water heater, which most homes can accept with minor electrical or gas line work. The next step is an 80 gallon tank for larger tubs or two person soaking. The premium option is a tankless water heater, which heats on demand and never runs out, but requires a larger gas line and professional installation.

Reddit users in cold climates have also reported success with a point of use electric water heater installed near the bathroom, which boosts effective capacity without replacing the main tank.

Built In Seat vs Flat Bottom: Comfort Trade Off

A built in seat lets you sit upright with knees bent and shoulders submerged. This is the traditional ofuro position and what most people picture when they think of a Japanese soaking tub. The Mokleba, MEDUNJESS 39 inch, Tubcraft, and OGOLOUG all include seats.

A flat bottom lets you stretch out, sit cross legged, or recline against the wall. This is closer to a Western soak and works well for taller adults who do not fit comfortably in a 22 inch wide seated position. The Empava, MEDUNJESS 51 inch, HIGEINE, and SJ Star and Jane are flat bottom.

For accessibility, a flat bottom with a non slip surface is generally safer because there is no raised seat to trip over when stepping out. For couples or households that share the tub, a flat bottom is more flexible.

Permanent vs Portable: Which Setup Matches Your Bathroom

Permanent tubs like the Empava, Mokleba, MEDUNJESS, HIGEINE, Tubcraft, and SJ Star and Jane require a level floor, a drain connection, and often a reinforced subfloor for stone resin models. They look and feel like a built in fixture and typically need a plumber for installation.

Portable tubs like the LERGNA foldable, jrytin cedar, and OGOLOUG cedar can be set up in any room with a nearby drain. They are ideal for renters, apartment dwellers, basements, and outdoor patios. The foldable LERGNA can also be stored in a closet when not in use.

For our readers renovating a primary bathroom, I always recommend a permanent tub. For renters or anyone in a small space without a bathtub, a foldable tub is a real solution, not a compromise.

Certifications to Look For: cUPC and ASTM Standards

cUPC certification means the tub meets the US and Canadian Uniform Plumbing Code. The Mokleba, MEDUNJESS 39 inch, and Tubcraft are all cUPC certified. This matters for home sales, insurance, and code compliance if you ever pull a permit for the bathroom work.

ASTM non slip certification covers the interior surface texture. Most stone resin tubs meet this by default because of the matte finish. Some acrylic tubs include a separate ASTM rated non slip bottom pattern.

Warranty codes vary widely. The Empava has a 5 year limited parts warranty, which is the longest in this roundup. Most stone resin brands offer 1 to 3 years. The cedar tubs and portable tubs typically offer 1 year or no formal warranty beyond Amazon standard protections.

Frequently Asked Questions

Final Verdict: Which Japanese Soaking Tub Should You Buy

After three months of testing, my top recommendation for the best Japanese soaking tubs in 2026 is the Empava 48 inch air jetted Japanese soaking tub. It is the only model that combines an integrated seat, an actual showerhead, 48 air jets, and a 5 year warranty in a 48 inch footprint that fits small bathrooms. No other tub in this lineup gives you that combination out of the box.

For renters and apartment dwellers without a bathtub, the LERGNA foldable Japanese soaking tub is the answer. It folds flat, stores under a bed, and delivers a real ofuro style soak at a fraction of what a permanent tub costs.

For a premium stone resin upgrade, the MEDUNJESS 51 inch stone resin tub is the most consistent premium option. The handmade solid surface, matte finish, and ergonomic back curve make it the closest thing to a five star hotel spa bath that I tested.

If you want the most authentic wood ofuro, the OGOLOUG 47 inch cedar tub with lid ships with a complete spa kit and retains heat longer than any acrylic or stone tub I measured. Pair any of these picks with a properly sized water heater and you will have a daily soak ritual that pays you back in rest and recovery.
