ᐅ Walk-in Shower, Splash Water, Do I Need a Door?

Hello everyone,

I need your advice 🙂. We are currently planning the bathroom in a new build. I have attached the bathroom layout.

The shower area is L-shaped, measuring 160x100cm (63x39 inches). The "open wall" is 80cm (31 inches) long, and the entrance to the shower is also 80cm (31 inches).

Question: Is the 80cm (31 inches) wall length enough to prevent water splashing outside the shower area? Or would it be better to install a door?

According to a consultant at the sanitary supply store, this should be sufficient. However, I have read online that a minimum length of 120-140cm (47-55 inches) is recommended.

P.S.: The thick wall between the toilet and shower likely contains the service shaft.

Well, doors and especially the hinges have always involved more cleaning effort... So if it’s possible to avoid them, I would rather do without.

I also think 80 cm (31.5 inches) is too narrow. And if you decide that it has to be a door in the end, it should definitely open inward, folding up against the wall. That way, you avoid the problem of dripping water on the outside.

I could imagine dimensions of 95/65 cm (37.4/25.6 inches). It might also be worth checking the standard widths available for shower doors and trying it out without one at first, so you can consider adding it later if needed.

I sketched the shower on the floor with the dimensions of 100x100cm (39x39 inches). Looking at it now, 100cm (39 inches) will never be enough to prevent water from splashing out. I believe at least 120cm (47 inches), preferably 140cm (55 inches), is needed. This is also confirmed by what I found in my online research. I should have "mapped it out" earlier 🙂. On paper, it’s quite misleading.

Well, basically there is nothing wrong with water splashing up to the 160 cm (63 inches) range. It only becomes critical when it ends up outside the 100x160 cm (39x63 inches) area. You should consider using a bath mat in front of the shower area. That’s why I suggested splitting the 160 cm (63 inches) into something like 95/65 cm (37/26 inches).

We are not worried about the 160 cm (63 inches); I am quite certain that 95 cm (37 inches) will not be sufficient and water will splash out.

I wouldn’t be so sure about that.

My bathroom has a walk-in shower with no raised threshold... very small, which is why the shower is pentagonal.

I’ve had a folding shower door that opens inward for over 10 years now. Usually, only the lower part shows water splashes. If my right shower wall were 95 cm (37 inches) long and the shower extended across the full width towards the bottom of the plan, I’m quite certain only a few splashes would land outside the shower area. And those would reasonably be caught by a shower mat.

Therefore, based on my current experience, I would plan with 95/65 (which should fit a standard shower door) in your case and initially try it without a shower door.
