Open shower - how deep?

Hello,
I would make the wall so that you can still comfortably enter from the front left (passage at least 80cm). So if the bathroom is 2.40m from top to bottom, I would make the shower wall about 1.40 to 1.60m.
For our old bathroom in the apartment, I found a shower wall from a dealer on the large platform with the A.... It cost half as much as the local hardware store at the time, including timely delivery up to the apartment. Installing it was no problem with two people with some technical know-how.

. I wouldn’t go to the glazier, but to the sanitary equipment supplier who offers suitable shower partitions and doors. We have an offer here for a pivot-folding door, 100 cm by 200 cm, real glass, silver shiny fittings, with delivery and installation about 900 euros. With the corner solution, you therefore need roughly 1500 to 2000 euros. Certainly much cheaper at the hardware store as well. If the glazier also offers it cheaper, let me know.

Why should one go to the sanitary equipment supplier? They are MUCH more expensive than glaziers and have a crucial disadvantage: they (almost) only know standard sizes.

It only splashes out minimally, we always place a shower mat or a towel in front anyway.

Likewise, one should of course place a towel on the floor behind the 1.20m.

I find that terrible and would always try to avoid it. Especially with underfloor heating where the floor can be comfortably walked on barefoot. Better to extend the shower wall by 10-20 cm.

why? When I get out of the shower or bathtub, I want to first place my dripping wet feet on an absorbent surface and not flood half the bathroom and then continue getting ready in a flooded bathroom. And such a cozy warm towel under the feet is more pleasant than bare tiles?

That wouldn’t be for me, constantly handling the wet cloth. Since the towel rack is located near the shower in our place, my idea is that after turning off the shower, I leisurely walk to the towel, with most of the water already dripping off my body, and then I rub off the rest with the towel. From my perspective, there shouldn’t be any puddles. The cozy warmth doesn’t come from the towel but from the underfloor heating.

Addition to the current discussion: I would then install the towel holder on the bottom wall. That way you can grab your towel right when you come out of the shower. Whether you put down a mat or not is then up to you.
