The shower area is the most essential part of the bathroom. When it comes to investing in new upgrades or remodeling your bathroom; one important factor to consider is knowing the standard shower sizes depending on the enclosure style and design.

Standard Shower Dimensions

This article aims to help you decide what size of bathroom shower dimensions you can accommodate in your home, as well as other fixtures and details you may want to incorporate.

Standard shower sizes

Square-shaped Shower

The smallest and most compact shower unit measures 32 x 32 inches and can go up to 34 x 34″ and 36 x 36″.

These types of shower can be installed in the corners of your bathroom, and for floorplans that don’t have enough space, this square-shaped design can also be installed along one wall.

Shower and Tub Combo

The most common and typical standard size for a shower and tub combo is 60 x 30 x 72 inches. This includes the measurements of the porcelain tub and the space around the tub’s basin, which is required when installing a combo unit. 

Usually, a shower and tub combo is installed, having a glass enclosure for a much more modern and clean look. The height of glass stall enclosures varies from 79 inches to 81 inches and 87 inches.

Stand-alone Shower Stall

A stand-alone shower stall size, usually varies based on the space allotted in the bathroom for the showering area.  The standard size for a stand-alone stall area without the tub is 48 x 36 inches.  This layout has the minimum space, which gives you more room to move around.

Steam Shower

The dimensions for a standard steam shower measure 60 x 48 inches. An 8ft ceiling or 96 inches is the best height for a steam enclosure, according to Mr.Steam [a manufacturer of steam units].

In many instances, a steam generator is added to a regular enclosure, and in this case, it would vary based on the design.

Shower Base Sizes

Shower base sizesA base is often called a “shower pan,” but they don’t mean the same thing. 

Standard shower base size

A shower base is a structure installed underneath the stall itself; it is a substructure typically made of concrete that is slightly sloped to allow water to flow properly into the drain. 

With standard bases, the drain is either located in the center or an offset drain hole.

A solid base surface can also be made of natural or cultured marble, tile laid over a mortar base, acrylic, or fiberglass.

It can even be made of various types of metal, such as cast iron or copper, which are extremely durable and a very luxurious design concept.

Standard Rectangular Show BaseStandard bases are usually in the shape of a square or rectangle, which ranges from 32 x 32 inches to 36 x 36 inches.

The standard size for a rectangular orientation is 60″ x 42″. 

For corner showers, the neo-angle base pans’ size ranges from 36 inches to 60 inches in diameter. 

Custom bases, which are built-in-place and constructed with a waterproof membrane, have made to order sizes.

A comfortable walk in enclosure size would have an average dimension of 48 inches x 36 inches and goes up to 48 inches x 48 inches to give a little bit of extra room. 

A large walk in shower can measure up to 60 inches x 36 inches and can accommodate a bench.

ADA Shower Size

The Americans with Disabilities Act (ADA) has established guidelines for the minimum dimensions of bathing facilities for people with disabilities.

ADA shower size

The ADA guidelines for a shower size:

ADA Transfer ShowerADA guidelines require that showers must have an inside dimension of 36 inches x 36 inches for accessibility and functionality. Thresholds in the transfer stalls should have a height maximum of ½ inch above the finished bathroom floor.

There should be a 36 inches minimum opening at the entry of the enclosure. Mounted L-shaped seats should be placed no more than 3” from the front entry, and a back wall grab should be 18 inches from the control wall.  There should also be a 36 inches (wide) x 48 inches (long) minimum clearance from the control wall.

ADA Roll-in Shower – designed as wheelchair accessible, ADA guidelines require a minimum inside enclosure dimension of 60 inches x 30 inches.

This would allow enough room for a wheelchair or chair.  Thresholds in the transfer stall should have a height maximum of ½ inch above the finished bathroom floor.  There should be a 60 inches minimum opening from top to bottom. 

Mounted L-shaped seats should be placed no more than 3” from the front entry, and a back wall grab should be 18 inches from the control wall.  There should also be a 30 inches (wide) x 60 inches (long) minimum clearance adjacent to the opening.

Size of a Two-person Shower

When designing a double shower, remember that the width is more important as the bathing area needs to be wide enough to accommodate two people. 

You also need to consider the shape of your wet room area and if you prefer an enclosed or open design.  It is all about what makes the couple most comfortable and have enough space to move around freely.

Two of the most common two-person (double) shower sizes are 3 feet x 5 feet and 4 feet by 6 feet; or some are even larger measurements depending on the space available. 

The shower curb, which keeps the water in the stall, should be at least 2 inches above the drain’s top but not more than 9 inches.

Shower Door Sizes

Shower Bench Size

Built-in shower benches can be incorporated when designing the bathroom layout.  They make a great and functional feature for a bathroom design.  The seat of the bench should be comfortable enough and, at the same time, should leave enough space for the bathing area. 

The height of the shower bench should be 1 inch lower than the back of your knees.  ADA recommends 17 inches to 19 inches from the floor as the best bench height.

ADA also recommends depth should be a minimum of 15 inches to 16 inches from the seat wall, and the seat rear edge should have a maximum of 2 ½ inches. 

A corner L-shape seat usually requires 14 inches to 15 inches seat depth.  A foot stool can be 10 inches to 13 inches minimum surface up to a maximum of 15 inches.

Shower Shelving and Niches

Shelving and niches are the perfect options for that extra storage space you may need in your bathroom area since it’s convenient, functional, and doesn’t take up much space.  A good location for the bathing accessories niche is on a wall opposite or adjacent to the showerhead.

Shower Niche Sizes

  • 12 inches (wide) x 24 inches (height) with a shelf in the middle 12 inches high is the best size recommendation
  • Shower niche depth: 2.5 inches minimum to 3.5 inches maximum
  • The recommended standard position of the niche should be at chest to eye level; at around 48 inches to 60 inches high. The bathtub niche should be placed lower; this means placing it just a little higher than the tub.
  • Other wall niche dimensions:
    • 6″ x 6″
    • 12″ x 12″
    • 24″ x 12″ (Best Recommendation)
    • 35″ x 12″
    • 47″ x 12″

An alternative to using a niche is to install a ledge. This is generally a half-height wall that protrudes several inches and allows room to sit shampoo, conditioner, and soap.

When renovating your bathroom, it is often practical to install your shower stall where the current footprint is rather than moving its location. You will need a good plumbing contractor and bathroom door installer to achieve favorable renovation results.
