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.
The reason that 24'' is approved for baths and powder rooms is because of doorswing into the room. If you are going to widen the doorway make sure that you have the clearance inside the bathroom to open the door all the way.
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. Normally with smaller single frameless shower doors, the glass thickness is 8mm, this keeps both the weight and cost down.

Being able to comfortably access your shower is the first important point, who wants to have to awkwardly side-step into their new luxury shower because the doorway is too narrow? I would recommend a minimum opening of 550mm, depending on the person's stature and mobility, I may increase the dimension.
How Big Should a Doorless Shower Be? A doorless shower layout requires a larger footprint than a standard tub or shower stall. Building codes may specify that a standard shower stall must be a minimum of 36 inches by 36 inches while the average doorless shower is about seven feet by four feet with many much larger.
A 30-inch x 48-inch clear floor space must be provided at shower stalls, parallel to the fixture and flush with the control wall. In 36-inch x 36-inch showers, the clear floor space must be positioned exactly as shown in the upper right diagram, with 12 inches offset behind the wall opposite the control wall.
The minimum size for a shower enclosure is 28” x 28” (700 mm x 700 mm), according to the International Building Code Association (IBCA). The standard shower enclosure size begins at 30″ X 30″ (700 mm x 700 mm), which is generally the smallest available to purchase.
What is the smallest recommended size for a shower? A shower should be 36 inches square (36 inches x 36 inches). For tiny spaces, 30 inches square (30 inches x 30 inches) is the smallest space that can be used for a shower.
The smallest allowable opening is 24 inches but this is only allowed if existing walls prohibit any type of modifications. How to measure a clear opening of a door?
If you have a small shower the sideways entry may be required but in general the most common straight in entry for people walking in is 24” wide.
24-inch shower doors are compact. They are suitable for small bathrooms or shower enclosures. The compact dimensions make these doors ideal for bathrooms with limited space. These doors offer a minimalist and sleek look to achieve a modern bathroom interior.
From the smallest shower sizes of 30 inches by 30 inches (the smallest allowed by the International Residential Code) to showers bigger than the already generous 48 inches by 60 inches, the shower size you choose will impact your comfort, lifestyle, and more.
The gap between a shower door and the wall depends on the type of shower door and the installation method. Generally, a gap of about ¼” to ⅜” allows for proper clearance, preventing the door from rubbing against the door frame or wall.
A 30 inch (760 mm) wide minimum by 60 inch (1525 mm) long minimum clearance shall be provided adjacent to the open face of the shower compartment.
Typically, the smallest shower size is 32 inches wide by 32 inches deep. However, the International Residential Code (which regulates houses, duplexes, and townhouses) allows for showers as small as 30 inches x 30 inches. Measurements go up incrementally from there, usually to about 36 inches by 60 inches.
Furthermore, the entry to the shower must be considered. ADA standards mandate that shower doors should not reduce the access width to less than 60 inches when the door is open. This ensures that entry and exit are possible without any barriers that might hinder a wheelchair user or someone requiring assistance.
Tip. The minimum allowable shower door width is 22 inches wide: Anything narrower than that may not be up to code.
Doorless showers offer several benefits that make them a smart choice for many homeowners. One of the main advantages of a doorless shower is its accessibility. With no threshold or glass barrier, these showers are easy to enter and exit, making them ideal for homeowners of all ages and mobility levels.
Don't underestimate your door size. Space may be limited but if your shower has a door make sure you can still fit through it! I would aim for 550mm at an absolute minimum, but just make sure it's designed with the main user in mind. You don't want to walk sideways into your shower everyday.
If you plan to apply some of the principles of “universal design” in your shower project, the stall should be at least 36-by-36 inches, or optimally a minimum of 42-by-60 inches. This no-threshold walk-in shower was designed for an individual with compromised mobility.
Keep in mind that the shower enclosure should be wide enough to allow easy movements. So 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.
