We usually recommend a minimum of 1300-1400mm in shower base length for a Walk-in shower and would probably require a bypass panel up until around 1700mm length shower base. A gap or around 500-600mm is suggested for the entrance to allow easy access.
You're looking at a minimum of 30 to 36 square feet. But before you grab the sledgehammer, make sure to check your local building codes because rules can vary. If a ¾ bath is more your style (just a shower, sink, and toilet), you can get away with 26–30 square feet.

The good news is that most people have at least that much space for a shower in their bathroom! The International Residential Code deems 30” by 30” as the smallest permissible footprint for a walk-in shower. The National Kitchen and Bath Association recommends a larger size; 36” by 36”, to be exact.
For Small Bathrooms

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.
For a small space, you might choose a walk-in shower with dimensions of around 35 x 35 inches (90 x 90 cm). This is considered a bare minimum as anything smaller than this can lead to water splashing outside of the shower itself.
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.
