Most shower stalls are between 32 and 36 inches wide. However, there are a few things to keep in mind when deciding on the width of your shower stall. First, the type of shower you have will dictate the minimum width required. For example, a walk-in shower will need to be at least 36 inches wide to accommodate the door swing. Second, the amount of space you have in your bathroom will also play a role in determining the maximum width for your shower stall. If you have a small bathroom, you may not be able to accommodate a larger shower stall. Finally, consider who will be using the shower stall and their needs when deciding on the width. For example, if you have young children who need assistance bathing, a wider shower stall may be necessary to make sure they can safely move around inside.
