ᐅ Walk-in shower: What is the recommended width for the entrance?

Hello forum,

once again, we need your collective expertise. Our shower measures 1.40 x 1 meter (4 ft 7 in x 3 ft 3 in). The entrance is planned on the 1.40 meter (4 ft 7 in) long side. Since the quote from our plumber for a glass panel/door seems too expensive, we are wondering if a walk-in shower would be enough?

We understand that some splashing may occur. However, we have sufficient slope for drainage, and a small towel in front should be enough.

How wide should the shower entrance be? 70 cm (28 in) ↔ 70 cm (28 in), or would 80 cm (31 in) – 60 cm (24 in) be better? Currently, we have an old corner shower with a 40 cm (16 in) wide entrance.

Good luck
