Bathtub Types and Sizes: Guide to Standard Tub Sizes

White bathtub

In any bathroom, the bathtub is one of the most important elements. It’s not just a functional fixture – it’s also the focus and centerpiece of the room, and choosing the right one can greatly enhance the overall visual effect of the space, adding an extra level of style and elegance. 

For anyone looking for a new tub or thinking of replacing an old one, a kitchen and bathroom remodeling expert, Villwell Builders, LLC  shares the standard bathtub sizes and dimensions – as well as the different types of tubs available.

1. Alcove

The most common type of bathtub. It is often a built-in tub shower combo that is surrounded by three walls to save space in small bathrooms. 

The standard tub size for an alcove fixture is 60 inches long, 32 inches wide, and 18 inches deep. 

2. Corner

A corner tub is a triangular bathtub that is inserted into the corner of your bathroom. You’ll often find cabinetry surrounding a corner bathtub on the sides that are not connected to a wall, or glass walls may stand in for sheetrock walls in some cases. 

Corner bathtubs usually have two sides of the same length with a width ranging anywhere from 48 to 72 inches and a depth of 18 to 20 inches.

3. Drop-in

A drop-in tub is built into a large frame that is set into an alcove. They often come with their own rim that is larger than the limited rims in alcove tubs. Drop-in tubs require a significant amount of space and are usually found in larger bathrooms. 

Drop-in tubs can be customizable in their size but they generally have a length of 60 inches, a width of 30 inches, and a depth of 16.

4. Walk-in

A walk-in tub has a door built along its side that lets you walk into the tub without having to step over the lip or climb in.

Walk-in bathtubs come in a variety of sizes ranging from 48 to 60 inches long, 28 to 36 inches wide, and 38 inches deep.

5. Freestanding

A freestanding tub is a large stand-alone tub that is not built into the walls of a room. The most important feature of a freestanding bathtub is that it’s not attached to any wall and siding. They are elegant and attractive, as well as being easy to maneuver around. 

Freestanding bathtubs are usually between 15 to 20 inches deep, 55 to 72 inches long, and 27 to 32 wide.

6. Soaking

A soaking tub is a kind of freestanding bathtub that you can place anywhere in your bathroom. Japanese soaking tubs are a popular choice for modern bathrooms. 

Soaking tubs can come in a range of depths, usually at least 27 to 34 inches. Since they are made for soaking upright, they can have a diameter as small as 40 to 50 inches.

7. Undermount

An undermount tub is similar to a drop-in tub except that its rim is covered with tile or stone framing. 

An undermount tub is usually 60 inches long, 30 inches wide, and 16 inches deep.

8. Whirlpool

A whirlpool tub is an acrylic bathtub that takes up a similar amount of space as an alcove tub. It uses air or water jet streams for a hydrotherapy effect that can keep your water warmer for longer amounts of time. 

Whirlpool bathtubs average about 60 inches in length, 32 to 36 inches in width, and 18 to 24 inches high.
