Hello everyone,
I’m an enthusiastic reader of this forum and have already gathered some helpful tips.
We bought a house built in 1979 and are in the process of modernizing it. The bathrooms are next on the list. I’ve attached a plan. Since the bathroom upstairs is quite small and the adjacent room is not in use, the idea is to combine both rooms. At the same time, we want to keep the changes to the plumbing as minimal as possible. The wooden ceilings on the sloped areas will be completely removed, and we want to include a walk-in shower, a bathtub, two sinks, and a toilet. Additionally, we would like to fit a washing machine into the bathroom!
We have already come up with some ideas and created an initial sketch. However, there are always very knowledgeable users here on the forum, so I wanted to reach out to get some ideas and suggestions.
Looking forward to your replies!!!
Best regards,
Jan

That could cause issues depending on how the screed is constructed. Usually, you need a 50mm (2 inch) drain pipe for the shower. If the shower is going to be flush with the floor level, a floor drain box will also be required. Additionally, the pipe needs to have a slope. This can easily add up to a depth of about 100mm (4 inches). Whether the ceiling structure allows for that much depth needs to be checked. However, there are certainly experts here who can help with that.

I assume there is no screed under the current shower and bathtub... ultimately, with your desired layout, it doesn’t matter because the bathtub is going back where it is now. Otherwise, you could make use of these openings for the wastewater pipes.

Now then: behind a partition wall, quite a few pipes can of course be hidden; you can also create a platform or half-height shelf along the exterior wall by installing the pipes there.

For the shower, I would generally recommend building a platform from wall to wall, but this idea probably won’t help much in your case since the wastewater pipe is most likely located at the bottom left, making the distance too long.
What is located under the current bathroom?
You mentioned two rooms that you don’t need... is it possible that the second room is on the other side of the bathroom? Then you would have a more centrally located wastewater pipe 😉

Edit: I forgot to mention the suggestion: break out the screed, then everything will be possible 🙂

Here, too, the question is how thick the screed is. If it is thick enough, then it is, of course, perfect.

Even with the concrete screed removed, not everything is possible.
In my case, the screed had to be removed anyway, but a walk-in shower couldn’t be installed in the desired location for that reason.
My screed was/is 7cm (3 inches) thick including insulation.

The screed can only be raised to a limited extent because the door threshold sets a measurement that must be observed. In most cases, the new screed will therefore be the same height as the old one.

Thanks for all your great suggestions and the many things I need to consider! Unfortunately, it’s not that simple 😉
