Standard Shower Bench Size

As a general rule of thumb, the standard shower bench size is 17 to 20 inches high, with a depth of between 15 to 16 inches. This will have any length needed to fit the shower wall and be able to sit comfortably.

Adding a bench inside your enclosure could change your daily shower routine, not just for your hygiene but also for adding a self-care system on a stressful day.

Safety is also a significant factor. As the National Council for Aging Care studied, people aged 65 and over are prone to head traumas and broken hips when an accidental slipping happens in the bathroom

When choosing your next seat, the standard size is always available.  Check out some of these considerations.

Bench Depth

The depth for the seating area should be between 15 and 16 inches from top to bottom for maximum comfort while seating. 

Bench Height

The standard or usual shower benches available on home depots or warehouses have a dimension of about 17 to 20 inches in height, from the floor to the seat. Tall enough for an average person to sit with his feet firmly placed on the floor.

Corner Shower Bench Dimensions

When you have a smaller shower and would like a seat but don’t have the space for a standard-size product, a corner shower bench is perfect. Corner-sized benches are great for any size of shower, but they are especially efficient for smaller ones. 

Side benches are usually smaller, triangular in shape, and sometimes have one curved corner. They offer functionality that takes up little space in the bathroom

A usual corner shower bench is 15 to 16 inches long from the floor to the seat and 18 to 24 inches wide. 

There are many advantages to corner seats, but there are also some downsides. 

Nearly all are smaller and do not meet the ADA’s recommended dimensions for seating products. An alternative to a corner shower bench that has ADA specifications is a folding L-shaped seat.

It should be, at best, 24 inches in length and has a minimum width of 24 inches, and it could be rectangular. This type of chair could be folded or mounted on the wall for added stability.

A 36″ x 36″ interior space in the shower is advisable to install a built-in bench with a height of 17″ to 19″ and a depth of 15″ to 20″ for the ordinary standard size seat. 

There are also various built-in seating styles you could adopt and install in your bathrooms— for example, a built-in corner seat for maximum shower space for a smaller bath.

Another alternative is the built-in sitting ledge, which can run along the total length of an interior wall. They are often installed near wall niches to keep bathroom accessories within easy reach.

The L-shaped design can also be wrapped on two wall sides of your layout. Additionally, there’s the U-shaped design to run along three sides of your shower or a floating bolt-on style that is space-efficient but still highly functional.

A built-in floating shower bench not only adds to your bath’s aesthetic appeal, acts as seating for comfort and functionality, but also doubles as an added storage unit. This type is also practical and space-saving, a plus for smaller bathrooms. The space on the bottom of the seat can easily be used for storage and extra leg space. 

An array of materials can be used on your seat, from granite and marble tile to bamboo and teak, which are water–resistant wood. 

Dimensions depend on the homeowners, but the ADA standard is a floating shower bench with a minimum height of 17 inches to 19 inches. It should have a depth of 15 to 16 inches, not too deep to make it hard to stand up, especially for a person with disabilities. 

Homeowners need to ensure that the floating structure will hold a weight of as much as 400 pounds. Read more about floating shower bench here.
