To determine the ideal walk in shower opening size for your space, consider the width of the shower itself. A typical shower width is around 30 to 36 inches.
The National Kitchen and Bath Association recommends a minimum of 30 inches of clear space in front of the shower opening for safe entry and exit. This allows for comfortable movement and reduces the risk of tripping or slipping.
For larger showers, consider a wider opening to match the shower's dimensions. A shower that's 60 inches wide, for example, would require an opening of at least 60 inches to accommodate the space comfortably.

The Space Needed
When planning a walk-in shower, it's essential to consider the space needed. A full bath with a walk-in shower requires at least 40 square feet of space, allowing for both a shower and a bath without constraint.
Interior designers recommend 40 square feet for a full bath with a walk-in shower. This is because it provides ample space for both a shower and a bathtub.
If the bathroom will only have a shower, you can go smaller. A three-quarter bath with just a shower can fit in about 27 to 30 square feet of space.
Measuring the space accurately is crucial to ensure the shower door fits properly.

Considering Bathroom Size
The standard shower size is 60 x 30 inches, typically found in a 5 x 8 feet bathroom, but you can size up to 60 x 42 inches for a rectangular shower or 42 x 42 inches for a square one.
A 30 x 30 inches walk-in shower is the smallest size allowed by building code, but it's not practical for every situation, especially where there is only room for a small shower.
For small bathrooms, the smallest possible walk-in shower dimensions for a square shower layout is 32” by 32”, while 30” to 35” is the smallest size for a rectangular walk-in shower.
In large bathrooms, you can opt for a large enclosure, with an average walk-in shower measuring 60″ x 42″ for a rectangular shower.
For standard-sized bathrooms, a square walk-in shower with a size of 36″ by 36″ or 38″ by 38″ is considered optimum, allowing easy movements during showering.
Here are some recommended walk-in shower sizes based on bathroom size:
Dimensions and Measurements
To choose the right walk-in shower, you need to consider the bathroom size, budget, and available shower area. A standard shower stall is 36 inches by 36 inches, but the walk-in shower dimensions can vary.
You should measure the entrance, height, and width of the shower area to determine the best size for your walk-in shower. The average and common dimensions for walk-in shower doors are about seven feet by four feet, which is much larger than the standard shower stall measurements.
The entryway of doorless walk-in shower enclosures is typically 2 feet. You can size up your walk-in shower, with dimensions going up to 60 x 42 inches for a rectangular shower and 42 x 42 inches for a square one, according to Kohler.
