Reveal by KOHLER makes bath remodeling simple—without sacrificing comfort, safety, or style. No matter what your reason is for upgrading to a walk-in bath, understanding the right dimensions helps you move forward with confidence. You don't need to measure anything. We'll take care of the measurements and make it simple.

 

The KOHLER walk-in bath is thoughtfully engineered, making it an ideal solution for homeowners converting an existing tub or shower combo without major structural changes. 

Average Walk-In Tub Dimensions

The average walk-in tub size is typically 60 inches long by 32 inches wide, with a height of 38 inches. Smaller walk-in tubs may measure 36 inches long by 32 inches wide, while larger options can reach 60 inches long by 40 inches wide. Most experts recommend that you leave extra room around the bath for improved ease of use and accessibility.

31 ½" Bathing Depth for Maximum Comfort

 

Designed for a deeply relaxing soak, the KOHLER walk-in bath features a 31 ½-inch bathing depth. Most standard 50-gallon water heaters can comfortably fill the bath, though water heater age and condition may impact performance.

 

This generous depth makes the bath especially appealing for seniors seeking full-body comfort.
