What is not flush with the tile??? The tiles are 120cm wide, just like the shower - on both sides, as mentioned, the LED strips in the corners as shower lighting are still missing, as well as in the niche.
I also find the handheld showerhead a bit too close to the edge - but purely visually. When showering it is actually very practical because it is never in the way. But visually, I initially criticized it. However, the installer did it deliberately and in hindsight I have to agree with him.
We wanted the stool exactly like this. Not too big so you don't lose space, but big enough to sit on. And we didn't want a hard corner in the area where you stand while showering and could bump into, hence the slope. And it is also very practical just the way it is. My only criticism in hindsight: the rain shower is centered in the shower - with the stool I would have now oriented it rather centered between the stool and the right wall. But how the stool would come was not yet finally decided during the shell construction and when showering it is not a disadvantage that the shower is visually somewhat too far left. The niche: how would you have stored shower gel etc.? I would even make the niche a bit bigger now...
We like the anthracite. We would have liked slate - but as natural stone that was too high-maintenance for us. The tiles are not completely one-colored but, like natural stone, somewhat variegated. As I said, we like it. The electric radiator, which is still to come, will also be anthracite.
That the tiles around the tub are now dark and not white is actually great. Because so much sun comes in through the double casement window - with white tiles it would probably be very glaringly bright.
