A modern Japanese soaking tub is designed for a deep, upright bath rather than a long, stretched-out soak. The right choice depends on more than style: check the tub’s outer dimensions, interior seating space, water depth, material, and drain setup before you buy. These five freestanding options range from a compact stone-resin oval to larger tubs with built-in seats, so you can compare their features against your bathroom and bathing preferences.

Our Picks: Best Modern Japanese Soaking Tub reviews
1. Weibath 40-Inch Stone Resin Tub: Best for a Small Footprint
The Weibath is the shortest option in this group, with exterior dimensions of 39.37 inches long, 22.83 inches wide, and 29.53 inches high. Its deep oval shape is intended for a full-body soak in a space-saving freestanding design. The matte-white stone-resin finish gives it a clean, modern look.
A drain and step stool are included, which is useful when planning the initial setup. The tub is described as accommodating one bather. Its compact size may suit a bathroom where a standard-length tub is not practical, but be sure to check the interior dimensions and usable bathing depth against your needs; the listed exterior measurements alone do not show how much room you will have inside.
Compared with the larger picks, this Weibath is easier to consider for a tight floor plan, while the HIGEINE and MEDUNJESS tubs with built-in seats make their upright seating more explicit. The product information does not state a water-depth measurement, so confirm the depth and drain connection details before ordering.
Pros:
- Compact exterior dimensions compared with the other options here
- Stone-resin construction and matte-white finish
- Drain and step stool are included
- Deep oval design intended for one-person soaking
Cons:
- Interior dimensions and water depth are not specified in the supplied product details
- Its narrow exterior width may feel limiting for some bathers
Verdict: Choose the Weibath if a compact stone-resin tub matters most and its interior fit works for your body and bathroom.
2. MEDUNJESS 46-Inch Acrylic Tub: Best for a Raised Seat
This 46-inch freestanding tub pairs glossy white acrylic with contours inspired by bamboo joints. Its integrated raised seat supports an upright bathing position, a defining feature for shoppers looking for a more traditional ofuro-style soak. The seat may also be useful for a foot soak or for anyone who prefers sitting upright instead of reclining.
The product information describes the acrylic as non-porous, stain-resistant, and designed to retain heat. Four hidden adjustable leveling feet help stabilize the tub on slightly uneven floors. A chrome pop-up drain is included but arrives uninstalled, and the listed package does not include a drain pipe.
Unlike the Weibath, this option has a built-in seat rather than a separate step stool. Its dimensions beyond the 46-inch length are not provided in the supplied details, so measure your floor space and confirm the full width and height before making a decision. Also check that your plumbing plan accounts for the missing drain pipe.
Pros:
- Integrated raised seat for upright soaking
- Glossy acrylic surface described as easy to clean
- Adjustable leveling feet for balancing the tub
- Chrome pop-up drain is included
Cons:
- Drain pipe is not included
- Full exterior dimensions are not specified in the supplied product details
Verdict: This is a strong option if an integrated seat and bamboo-inspired styling matter more to you than a stone-resin build.
3. MEDUNJESS 43-Inch Square Acrylic Tub: Best for a Certified Compact Pick
This freestanding MEDUNJESS model measures 43.31 inches long, 27.5 inches wide, and 25.59 inches high. It has a square profile, a glossy white finish, and an integrated seat. The listed weight is about 110 pounds, so include the tub’s weight in your delivery and installation planning.
The acrylic construction is described as durable and easy to maintain. The product listing also identifies the tub as cUPC certified and says it has an integrated overflow and drain system. Those details make this a practical choice for shoppers who want a clearly specified compact footprint and a built-in seat, though the interior bathing dimensions are not given.
Its width is greater than the Weibath’s listed width, while its overall length is shorter than the 46-inch MEDUNJESS model. Compare the full footprint with your bathroom layout, and confirm exactly what drain hardware is included for your installation. A freestanding tub still needs compatible plumbing and enough access for setup.
Pros:
- Specific exterior dimensions make space planning easier
- Integrated seat and overflow-and-drain system
- Glossy white acrylic finish
- Listed as cUPC certified
Cons:
- Interior dimensions and water depth are not provided
- The listed weight may require planning for delivery and placement
Verdict: Consider this tub if you want a compact acrylic option with a seat, a defined footprint, and listed cUPC certification.
4. HIGEINE 47-Inch Stone Resin Tub: Best for Deep Seated Soaking
The HIGEINE is a freestanding stone-resin tub measuring 47.2 inches long, 27.6 inches wide, and 26 inches high. Its molded seat is about 22.8 inches wide and 12.2 inches deep. The listing gives a water depth of 18.66 inches, making this one of the more clearly described choices for shoppers focused on an upright, deep soak.
Its one-piece construction has a matte-white finish and rounded corners. A toe-tap drain and an integrated overflow are included, and the listing describes the drain connection as a standard size for US plumbing setups. Routine care is described as wiping the surface with a soft cloth, warm water, and mild soap; avoid assuming that any cleaner is suitable without checking the manufacturer’s care instructions.
This model is wider than the 43-inch MEDUNJESS tub and is not as short as the Weibath, so compare its full footprint with your available space. The product title refers to a 20.5-inch depth, while the detailed description specifies 18.66 inches of water depth. Because those figures may refer to different measurements, verify the exact interior and fill-depth specifications before purchase.
Pros:
- Integrated molded seat for upright bathing
- Listed water depth of 18.66 inches
- Stone-resin, one-piece construction
- Toe-tap drain and overflow are included
Cons:
- Conflicting depth figures in the supplied product information should be clarified
- Its 27.6-inch width needs careful floor-space planning
Verdict: Pick the HIGEINE if a built-in seat and stated deep-soak water depth are priorities, after confirming the depth measurement with the seller.
5. MEDUNJESS 51-Inch Black Stone Resin Tub: Best for a Dramatic Finish
This 51-inch MEDUNJESS tub stands out with a black matte finish and a solid-surface construction described as a blend of acrylic and natural minerals. Its one-piece design is intended to create a seamless look, and the listing describes the surface as non-porous and resistant to stains, scratches, and chipping. The product information also describes a slightly matte, silky texture.
The tub is presented as an ergonomic soaking design, but the supplied details do not give its width, height, seat layout, or exact water depth. That makes it harder to judge fit and bathing position from the listed length alone. The faucet is not included, so plan for that separately and confirm what drain components come with the tub.
Compared with the white options, this model is the clearest choice for a dark focal point in a modern bathroom. Its larger stated length may suit shoppers with more room, but do not assume it will fit based on length alone. Ask for the complete dimensions and installation requirements before committing.
Pros:
- Distinctive black matte finish
- One-piece solid-surface design
- Construction is described as a blend of acrylic and natural minerals
- Listing describes a non-porous surface
Cons:
- Full exterior dimensions and exact water depth are not provided
- Faucet is not included
Verdict: Choose this model for its black finish and solid-surface style only after confirming the complete dimensions, bathing layout, and included plumbing parts.
How to Choose a Modern Japanese Soaking Tub
Measure the Full Footprint
Measure the space where the tub will sit, including room to walk around it and access the drain. Compare the listed length, width, and height with your bathroom measurements, and leave room for the faucet and plumbing where needed. Some product details provide only a length, so request the complete exterior dimensions before buying if width or height is missing.
Check the Interior Seating and Water Depth
Exterior dimensions do not tell you how much usable bathing space is inside. Look for interior measurements, seat dimensions, and the stated water depth. If you want a traditional upright soak, an integrated seat can help define the bathing position. Confirm whether a depth figure describes the tub’s inside depth or the actual water level; those measurements are not always the same.
Choose a Material and Finish That Fit Your Priorities
The options here include acrylic and stone-resin or solid-surface designs. The listings describe acrylic as easy to clean, while the stone-resin choices emphasize a substantial, seamless appearance. Finish also affects the look of the room: glossy white, matte white, and black matte each create a different effect. Follow the manufacturer’s care instructions, especially when selecting cleaning products.
Plan for Drainage and Faucet Parts
Check whether the tub includes a drain, overflow, drain pipe, and faucet. These products vary: one listing includes a drain and step stool, another includes a pop-up drain but not a drain pipe, and the black tub listing says the faucet is not included. Confirm the drain location and connection requirements with your plumber before ordering so the tub works with your bathroom’s plumbing.
Consider Entry, Stability, and Installation
A raised seat may suit you if you prefer sitting upright, but consider the tub’s height and how you will step in and out. Adjustable leveling feet are specified on one acrylic model, while other options may need a different approach to leveling. Ask your installer about floor support, delivery access, and how the freestanding tub will be positioned and connected.
Match the Tub to Your Bathing Habits
Think about whether you want a short foot soak, a deep upright bath, or more room to shift your posture. A smaller exterior can save floor space, but it may also mean less room inside. A longer tub is not automatically more comfortable for every bather, so compare interior shape and seat placement with your own preferences before choosing.
Frequently Asked Questions
What makes a Japanese soaking tub different from a standard bathtub?
Japanese soaking tubs are generally designed for a deeper, upright bathing position rather than stretching out lengthwise. Several options in this selection include built-in seats, while others rely on a deep tub shape or a separate step stool. Check each model’s interior dimensions and water depth to see whether it suits the way you want to bathe.
Which tub in this selection is the most compact?
The Weibath has the shortest listed exterior length at 39.37 inches, and it is also the narrowest by the supplied measurements. Its listed dimensions are 39.37 inches long by 22.83 inches wide by 29.53 inches high. Confirm the interior size and water depth before deciding whether it will be comfortable for you.
Which options include a built-in seat?
The 46-inch MEDUNJESS acrylic tub, the 43-inch MEDUNJESS acrylic tub, and the HIGEINE stone-resin tub are described as having integrated seats. The Weibath listing mentions a step stool, not a built-in seat. The supplied information for the 51-inch black MEDUNJESS tub does not specify a seat.
Are drains and faucets included?
Included parts differ by model. The Weibath includes a drain, the 46-inch MEDUNJESS includes an uninstalled pop-up drain but no drain pipe, and the HIGEINE includes a toe-tap drain and overflow. The 43-inch MEDUNJESS is described as having an integrated drain and overflow system. The black MEDUNJESS listing says its faucet is not included. Check the product details and confirm compatibility with your installer.
Which tub has the clearest stated water-depth information?
The HIGEINE listing specifies a water depth of 18.66 inches. Its title also mentions 20.5 inches, so ask the seller to clarify which measurement applies before buying. The supplied details for the other models do not state an exact water depth.
Can these freestanding tubs fit in a small bathroom?
Some are designed with compact dimensions, but fit depends on more than the tub’s length. Check width, height, access routes, space around the tub, and plumbing clearance. The HIGEINE listing describes its footprint as suitable for compact spaces, while the MEDUNJESS black tub has a stated length of 51 inches but lacks full dimensions in the supplied details.
Final Recommendation
For a compact stone-resin option with a clearly stated footprint, the Weibath is the easiest fit to assess, though you should confirm its interior size and water depth. If you want a built-in seat, compare the 43-inch MEDUNJESS, 46-inch MEDUNJESS, and HIGEINE based on their dimensions and drain details. The HIGEINE provides the most specific stated water-depth figure, but its listing has conflicting depth measurements. For a black focal point, the 51-inch MEDUNJESS may appeal, provided you first verify its full size and installation requirements.
