New construction bathroom floor plan upper floor - feedback?

that you have an unrestricted view outside while bathing.

Eight, nine, ten - yes, what is there to see?

T-walls with washbasin must be floor-to-ceiling to be stable, as far as I know. Darkness in walk-in showers can be solved with lighting (oh wonder ;-)). For this reason, I wouldn’t tie myself to glass, glass partitions only cause work.

T-walls with washbasins must, to my knowledge, be room height to be stable.

I can give your knowledge some new experiences:

We built our T-wall ourselves, which ends about 30cm below the ceiling.
It is ultra stable.

For this we used:
- vertical wooden beams made of KVH at the ends and at the T-junction for stabilization
- completely clad with OSB and a layer of drywall panels on top
- you can literally throw yourself against it and nothing happens.
- for safety, one could weld and insert a suitable T-iron at the top (which is unnecessary)

Podest for bathtub?
Bathtubs are recessed into the screed in new buildings so that you can also easily get into the tub...

If you can look out, you can also be seen.... firstly, when bathing you lie down, so you mostly look at the ceiling, 2. I would want to move naked in front of the window (laugh, in full shot: man gets into the tub, lifts his little leg, wow, what a sight, woman comes along, leans over, wow, gets caught with her knee, falls against the window, wow, ... oh no, we still have the roller shutters down... they are only opened when you are sitting in the tub... and then? Somehow I have Loriot in my head now [emoji1]
You will then only see the height of the upper floor when looking out the window... or yourself ;)

Edit: 3. who cleans the window... it's already annoying when a tub of normal height stands in front of the window, but one with a podium?

P.s. Always plan a false wall on load-bearing walls for water pipes!

T-walls with washbasins must be room-high to be stable, to my knowledge.

Then the T would have missed its shape ;-) As long as the longitudinal and crossbars of the "T" are firmly connected to each other, I see no stability concerns.

Because of the ventilation pipe from the toilet flush, a wall covering is created which I consider not to be optimal. What do you think, how could this be arranged optimally?

Is there already an optimal solution for this?
