Your opinion on bathroom planning

Hello, attached are the drawings of our bathroom planning... one of them from a professional (with the round bathtub).
What do you think about it?
And, I have attached the measurements of the bathtub... do you think it is really comfortable and big enough?!
What is important to us is a 120*100 shower and a comfortable bathtub.
Best regards

I once had the Kaldewei Studio/Studio Star corner bathtub, you can google it, it is very comfortable because it is deeper. However, I am 165 cm tall, my husband is only 178 cm, he also found it great. However, it was a bit cramped for two, especially for one, because the foot area was narrow - that is not the case here.

I do not find the last 3 bathroom designs successful, as the location of the bathtub does not match with the windows. It looks absolutely arbitrary and unplanned. What is the function of the small window?

Can recommend the Kaldewei Mega Duo - very comfortable; also for two people. Additionally, water-saving

Hello, the second window is still a leftover because there used to be two rooms. Without the second window, it is unfortunately very dark. What do you mean by the position of the bathtub not fitting the window?

The tub is placed there in the corner, and somehow there is a small window also quite in the corner..., another one simply starts at about the last fifth of the tub and extends beyond the tub’s edge.

Is it an old building that has been renovated? What are the sill heights of the windows?

Here’s a tip: the 105 next to the door will be very tight with a 20 cm platform depth if the door frame still needs space. Or is the frame already included? This comes down to centimeters in the planning; an 80 cm tub, when tiled, is then 83 cm, and the platform of 20 cm must have a raw construction depth of less. When it comes to the platform, keep in mind that it becomes relatively high at the toilet – for the tub, however, I would make the platform at the tub height. That would mean you have an offset.

I would go with the version from the planner. The washbasin belongs next to the door for me. I always need to access it and want quick access, not having to go unnecessarily to the end of the room first. The toilet is the second most important for me; I also want to get there quickly and without obstacles. Currently, my toilet is behind the door, and I find that totally annoying. Many want the toilet out of sight. It's all a matter of taste. I like having the shower behind the door. The door is always closed when showering anyway, and if it fits space-wise, it’s the optimal use of space. Having the shower next to the bathtub is, in my opinion, a bit old-fashioned and often looks cramped in small bathrooms. That’s why I think the diagonal arrangement is great. Additionally, I can well imagine looking out the window while bathing. I once had a skylight above the bathtub and found that pretty awesome.

Which bathtub to choose, I unfortunately cannot say, as this problem will come up later and I find the selection and price range very confusing.
