Shower easy to care for and still beautiful

It doesn’t matter whether you clean a tiled wall or a glass wall/door. I would probably prefer the glass walls. They are easier to maintain than "rotting" grout. Besides, you’re creating a dark hole. P.S. With the hand-drawn version you made, water splashes vigorously through the tiny and impractical passage. My conclusion: terrible idea, dark and too high-maintenance.

No, that’s not true, you don’t have to squeegee or clean a shower wall after every shower, otherwise unsightly water drops remain. That does make a difference. And there are also large tiles, so there are only a handful of grout lines in the entire shower. The dark hole can be illuminated; the lack of a view doesn’t bother me when showering, although I don’t want to make the bathroom feel cramped...

I would definitely not build a shower with an entrance measuring only 50cm. An alternative to the glass door, if you do not want one, would be a shower curtain.

the children and also for quickly washing feet, etc.

We have always washed our children and feet in the shower...

No, that's not true, you don't have to wipe down or clean a shower screen after every shower, otherwise unsightly water droplets remain.

If you don't want unsightly (lime) spots, you have to do it. For me and probably most people, it is a matter of course to wipe down the shower after use. And when I see your shower vs. water droplets/wiping down, your shower loses by a mile. But as always, this is just an individual perspective. However, you haven't received any agreement so far; maybe this will encourage you to think about it.

We had built this once, but without this small corner. In general, I prefer a half-high masonry wall with a glass part set on the outer edge, creating a storage surface for shower gel etc. on the inside. Currently, we have a full glass wall with 140 cm, and water goes minimally around the corner. But since there are tiles everywhere and underfloor heating, I don’t see a problem there. Everything longer feels too big to me again. In the newly planned bathroom, it will be half-high again and without any rods etc., which I don’t like that much. Therefore, a small kink is enough to be able to install it without mounting. With full glass, you always have to kneel down to wipe off, despite having a longer squeegee... with tiles, it’s okay for me if it’s not wiped off every time. I find a 50 cm passage borderline, but you have a live example at your place to estimate that. Here with us currently (not in the picture), the passage is exactly 70 cm, and at the lower end, there is a kind of privacy wall for the toilet, so there is freedom around the upper body. That is extremely comfortable to walk through. I would actually reconsider the topic of bidet and foot washing etc., because you lose shower comfort with that. In the tub or shower, you can also briefly wash your feet in my opinion. Our second shower here is 120 cm deep with full glass and at the end a 30 cm fixed glass part, so there is also a 70 cm passage. Some water goes out there too, but really very manageable and also on tiles with underfloor heating, so no problem. After various versions, the optimal size for me would be 90-100 cm wide and 140 cm long; half wall and half glass, period. Passage about 70-80 cm.

Unfortunately, I didn’t quite understand the 120 deep and the additional 30 fixed glass part? Fixed glass part around the corner or where exactly is the 30 cm glass? I can’t imagine the passage now. You still have a fixed glass on the open side? Could you please draw that for me again? Our second idea was also to build a 120-130 half-high wall and leave it open towards the toilet, because in the architect’s drawing the toilet and bidet are already very far apart, nobody needs that. My brother has 120 space requirement for both and that’s more than enough, meaning for the shower + freedom of movement there would then still be almost 2 meters, with a 130 cm shower still 70 cm to the toilet.
