ᐅ Open Shower – How Deep Should It Be?

Hi,

in our bathroom (the developer is currently building the house), the shower is to be installed in a corner. On the bathroom side (right side, see photo) no partition is planned. This can/should be done by us.

There are two options:
Either just a glass panel on the right, leaving the shower open on one side, or
a glass panel on the right plus a door on the remaining side.

The shower has a floor-to-wall drain, so there is no shower tray.

Question:
How deep/long should the right side be to prevent the bathroom from flooding when using a rain shower?

And second question:
If we have this done by a glazier (area Munich), what is a fair price? According to Google Maps there seem to be thousands of glaziers offering this, and I obviously cannot contact them all.

Ours is 1.20m (4 feet) and it is only slightly wet outside after showering...

Our masonry side wall is 1.30 m long (4 feet 3 inches), and the rain showerhead is attached to it. There is only minimal splashing; we always place a bath mat or a towel in front of it anyway. I find that with the rain showerhead, there is significantly less splashing compared to a regular showerhead, since the water streams are directed straight downward.

By the way, if the open shower is properly installed, you will not flood the bathroom, as a slope is planned so that the water flows back into the shower instead of outside.

In my opinion, an open shower should be at least 140 cm (55 inches), preferably 150 cm (59 inches) deep. Instead of going to a glazier, I would recommend visiting a bathroom supplier who offers suitable shower partitions and doors. We received a quote for a folding pivot door, 100 cm by 200 cm (39 by 79 inches), made of tempered glass with polished silver fittings, including delivery and installation, costing about 900 euros. With a corner solution, you can roughly estimate between 1500 and 2000 euros. It’s probably significantly cheaper at a DIY store. If the glazier can offer it for less, please let me know.

We once asked a HVAC/plumbing specialist who regularly installs bathrooms, and he said that from 1.20 m (4 feet) width onward, you can do it without a door. Of course, it also depends somewhat on how you shower.

You can always retrofit later, right? If the floor plan allows it. Also, behind the 1.20 m (4 feet) space, you should of course place a towel on the floor.

Our glass wall in the walk-in shower is one meter wide. Originally, it was planned to be 1.20 m (4 feet) wide, but then it would no longer be easy to access the shower with a wheelchair. Still, no water splashes out, and both my men are around 1.90 m (6 feet 3 inches) tall.
