Japanese Bathroom Ideas

A Japanese bathroom is built around one routine: wash first, then soak in a deep tub. That shapes the room, from the open washing area beside the tub to the separate rooms for undressing and for the toilet. These ideas cover traditional wooden tubs, onsen and ryokan styles and modern versions in concrete and slate. For a softer mix of Japanese and Scandinavian design, see the Japandi bathroom ideas. These bathrooms are design concepts rendered with AI; try one on a photo of your bathroom.

How a Japanese bathroom is laid out

According to Japan Guide, the bathroom in a typical Japanese home is two rooms: an entrance room where you undress, which has the sink, and the bathroom itself, with a shower and a deep tub. The toilet is usually in an entirely separate room.

Keeping the sink and towels in the dressing room lets the bathroom be a wet room from wall to wall: the whole floor can get wet and drains away, and the tub and the washing area share one space.

A typical Japanese home bathroom starts with this room: a place to undress, with a sink, shelves of towels and a laundry basket. A frosted sliding door leads to the bathroom with the tub.

Wash first, then soak

Japan Guide describes the routine: you rinse your body outside the tub with the shower or a washbowl, then get into the tub, which is used for soaking only. Wikipedia adds that washing is done in the same room as the tub, seated on a small stool with a hand-held shower. Because no soap goes into the tub, the water is usually left for the next person in the house.

So the washing area needs its own floor and drain, a hand shower mounted low, a stool and a bucket, and a mirror and shelf at seated eye level.

This is where you wash before soaking: a low wooden stool and bucket face a hand shower and a small mirror mounted at sitting height, on a tiled floor with its own drain. The tub waits just to the side.

The ofuro tub

Ofuro is the Japanese word for the bath. Wikipedia describes a traditional tub as square and deep enough that the water covers the bather's shoulders, and Japan Guide notes the water is typically hot, between 40 and 43 °C. A square tub also saves length in a small room.

Wooden tubs are often hinoki, a cypress that Wikipedia lists among materials for baths and describes as highly rot-resistant and lemon-scented. Stone, tile and modern acrylic tubs are common too. A full deep tub is heavy, so check the floor, and ask your supplier how to care for wood.

A deep square wooden tub, filled almost to the rim, fits into the corner of a small room under a little square window. A stool and bucket in front mark the washing area.

The toilet room

With the toilet in its own small room, the bathroom stays a room for washing and bathing. The toilet room can be simple and still feel finished: a wall-hung toilet, a small hand basin, a shelf and one quiet detail such as a branch in a vase or a latticed window.

In many Japanese homes the toilet has its own small room, apart from the bath. This one has a wall-hung toilet, a stone hand basin on a wooden shelf, clay plaster walls and a latticed window.

Color

The palette comes from the materials: pale hinoki and cedar, grey stone and slate, plaster and the green of a garden view. Darker versions use charcoal plaster and black stone, with warm light from a lantern or wall lamp.

Black slate covers the floor and walls, and a wall of vertical cedar slats warms one side. A deep wooden tub, a low cedar stool and a hand shower complete a darker, modern version.

Japanese or Japandi?

A Japanese bathroom follows the Japanese routine: a deep soaking tub, an open washing area with a stool, and separate rooms for undressing and for the toilet. A Japandi bathroom borrows the look, light wood, stone and calm, but usually keeps a Western layout with a vanity, a toilet and a walk-in shower in one room. For that version, see the Japandi bathroom ideas.

Common mistakes

A deep tub with no washing area beside it, which breaks the routine the room is built for.
A shower head mounted too high to use from a stool.
Wood or paper finishes in the wet area without checking how they are protected.
Too many accessories when a stool, a bucket and one shelf are enough.

Frequently asked questions

What is a Japanese style bathroom?

A bathroom built around washing first and then soaking: an open washing area with a stool and a hand shower, a deep soaking tub, often in wood or stone, and natural materials. In a typical Japanese home, the sink is in a separate dressing room and the toilet is in its own room.

Why are Japanese bathrooms different?

Because of how the bath is used. You wash and rinse outside the tub, so the tub is only for soaking, and the water is usually left for the next person in the house. That is why the bathroom has an open washing area beside the tub and, in a typical home, the toilet is in a separate room.

What do you call a Japanese bathroom?

The bath or tub is called the ofuro. The whole room is usually just called the bathroom; in a typical home it is entered through a separate room for undressing, which has the sink.

What is special about a Japanese soaking tub?

It is deep rather than long. A traditional tub is square and deep enough that the water covers your shoulders, and it is used only for soaking, after washing. Wooden versions are often made of hinoki, a rot-resistant, lemon-scented cypress.

Can I have a Japanese bathroom in a small space?

Yes. A short, deep square tub needs less length than a Western bathtub, and the shower and washing area can share the same wet floor beside it, as in the Small Japanese Apartment Bathroom idea above.

What is the difference between a Japanese and a Japandi bathroom?

A Japanese bathroom follows the Japanese routine and layout: a deep tub, an open washing area and a separate toilet room. A Japandi bathroom takes the materials and calm of Japanese design but usually keeps a Western layout, with the vanity, toilet and shower in one room.
