Japanese soaking tubs have become increasingly popular in modern bathroom design, particularly among homeowners seeking relaxation, wellness, and space-efficient solutions. Unlike traditional Western bathtubs, Japanese soaking tubs prioritize deep immersion, heat retention, and mindful bathing, transforming everyday routines into a spa-like experience.
In this guide, we’ll explore what a Japanese soaking tub is, why it’s designed differently, how to choose the right size, and whether it’s the right fit for your bathroom.
What Is a Japanese Soaking Tub?
A Japanese soaking tub—often referred to as an ofuro—is a deep bathtub designed for upright sitting rather than reclining. It originates from Japan’s long-standing bathing culture, where soaking is meant for relaxation and recovery after washing.
These tubs are typically shorter in length but significantly deeper than Western bathtubs, allowing the entire body to be submerged in warm water.
How a Japanese Soaking Tub Is Different From a Western Bathtub
The biggest difference lies in bathing posture and water depth. Western bathtubs are long and shallow, designed for lying down, while Japanese soaking tubs are short and deep, designed for vertical soaking.
This difference results in better heat retention, reduced water splashing, and a more meditative bathing experience.
Why Japanese Soaking Tubs Are Deeper but Shorter
Japanese bathrooms are traditionally compact, so tubs evolved to save floor space while still offering full-body immersion. Depth replaces length, making the design both practical and comfortable for small rooms.
Why Japanese Soaking Tubs Are So Popular
Full-Body Soaking in a Compact Space
Despite their smaller footprint, Japanese soaking tubs allow users to soak up to the shoulders, promoting circulation and muscle relaxation.
Better Heat Retention and Relaxation
The deep water column holds heat longer than shallow tubs, which means less hot water needs to be added frequently, resulting in a more relaxing experience.
Ideal for Urban Homes and Small Bathrooms
For apartments, townhomes, and modern condos, Japanese soaking tubs deliver luxury-level comfort without taking up excessive bathroom space, making them an ideal small bathroom bathtub solution for urban homes and compact layouts.
Japanese Soaking Tub Sizes Explained
Typical Length, Width, and Depth
Most Japanese soaking tubs range from 40–55 inches in length, with depths that often exceed 24 inches—much deeper than standard tubs.
Why Depth Matters More Than Length
Depth determines how fully your body can be submerged. A deeper tub improves heat retention and relaxation far more than extra length.
Japanese Soaking Tub Sizes for Small Bathrooms
Compact models are available specifically for tight layouts, often under 48 inches long, while maintaining generous soaking depth.
Japanese Soaking Tub vs Western Bathtub
Water Usage and Soaking Experience
Although Japanese tubs are deep, their smaller surface area often means they use similar or even less water than standard bathtubs or some large freestanding tubs while delivering a superior soaking experience.
Space Requirements and Bathroom Layout
Western tubs require long wall space, while Japanese tubs can fit neatly into corners or compact layouts.
Which One Is Better for Small Bathrooms?
For small bathrooms, Japanese soaking tubs are usually the better choice due to their compact footprint and ergonomic design.
Do Japanese Soaking Tubs Need a Heater?
Traditional Soaking vs Modern Heated Tubs
Traditionally, hot water is simply added as needed. Modern designs may include electric or built-in heaters to maintain water temperature.
Pros and Cons of Built-In Tub Heaters
Pros:
- Maintains consistent temperature
- Extends soaking time
Cons:
- Higher upfront cost
- Requires electrical planning
When a Heater Is Worth It
If you enjoy long baths or live in colder climates, a built-in heater can be a worthwhile upgrade.

Installation Considerations
Floor Load and Bathroom Structure
Because soaking tubs are deep and hold a significant volume of water, ensure your floor structure can support the weight, especially in upper-floor installations.
Drainage, Plumbing, and Ventilation
Proper drainage and ventilation are essential to prevent moisture buildup and ensure long-term durability.
Freestanding vs Built-In Japanese Soaking Tubs
- Freestanding tubs offer design flexibility and visual impact.
- Built-in tubs provide a cleaner, integrated look and may save space in narrow bathrooms.
