Fixed glass shower doors come in a variety of widths, from 22 inches to 36 inches. The width of your fixed glass shower door will depend on the size of your shower opening. A 22-inch fixed glass shower door is a good option if you have a small shower opening, perhaps in a guest bathroom.

Homeowners often ask if a 24-inch shower door is too small. The answer depends on your bathroom and shower sizes.

These doors are typically used for narrow shower stalls and can be a smart choice for ensuite or guest bathrooms.
The realistic minimum shower door width tends to be 550mm, when the space is perhaps tighter, but when the customer still wants to make the most of the opening into the shower space.

For Small Bathrooms

The International Residential Code stipulates that showers must have at least 30 inches by 30 inches of space as a minimum requirement. Yet many people prefer roomier configurations such as those measuring 48 inches by 36 inches due to the comfort level they provide during use.

Shower doors come in a variety of sizes and dimensions to fit your walk-in shower. However, the standard shower door size is between 22 inches and 36 inches wide and 72 inches high. If the width is more than 36 inches, an extra panel may be needed to support the extra weight.
