Shower Size

Most prefabricated showers come in standard sizes from 32 inches (813 mm) to 48 inches (1219 mm) square, but in recent years expanded options are becoming more common.

• The recommended interior shower size for one person is at least 36 inches by 36 inches (914 mm by 914 mm) (see Figure 6.46). This allows one person to comfortably stand in the shower with arms raised to wash their hair. The IRC building code states that the minimum in­terior shower size is 30 inches by 30 inches (762 mm by 762 mm), but this is a tight space for most adults.

• Check angled showers to make sure a 30-inch (762 mm) disc will fit into the shower floor. This will meet minimum code requirements. A larger disc area should be specified when user needs require more space.

• A 36 inch by 36 inch (914 mm by 914 mm) size is acceptable for a transfer shower to be used by a person transferring from a mobility aid. See chapter 8, "Accessibility in Practice," for more discussion.

• It is recommended that a roll-in shower used by a person with a bathing wheelchair should be at least 36 inches by 60 inches (914 mm by 1524 mm). Access Standards allow for a 30 inch (762 mm) minimum width, but 36 to 42 inches (914 to1067 mm) makes it easier to contain the water in the shower.

For a person to move out of the shower spray inside the shower, a 36 inch by 42 inch (914 mm by 1067 mm) shower should be considered (see Figure 6.47). Larger prefabricated showers are avail­able, and custom showers can be designed to meet the needs of the user. (Check that any prefab­ricated shower will fit through the bathroom door.) In a shower at least 60 inches (1 524 mm) deep, it is possible to control the spray within the shower. In a two-person shower, make sure there is room for both people.
