Appel200031 May 2020 19:31Hello and good evening!
In our bathroom, we will be building the wall structure described below as a lightweight/drywall construction. It was supposed to be a solid wall originally, but that’s a long story—solid isn’t an option, so better not ask.
On the right side of wall "2," the toilet will be mounted. It is a Geberit UP 320.
The drywall installer says that the load from the toilet needs to be transferred to the side walls because the entire wall does not reach the ceiling and therefore lacks sufficient stability. He recommends using a GIS system to transfer the toilet’s load to the side walls, which makes sense to me.
The plumber says that if an OSB board is installed at the back of the wall, it will hold without a GIS.
It’s easy enough to find out what a GIS is.
But I haven’t found any information yet about the cost of such a construction for our desired location or where to order one. Could a construction made from suitably sturdy wooden beams be built instead, which would then also be covered with drywall?
What do you think?
GIS, wood, or nothing at all?
Regards
Appel

The answer is relatively simple: nothing is impossible. Wood definitely works, but, well... You can’t avoid GIS, which is why it exists. Every plumber has it, and it is available at every hardware store.

Thanks for your opinions!
Well, you still need to fix the Duo Fix in place. On the floor and on the back wall. However, the back wall doesn’t hold much, so the idea/opinion was to attach the DuoFix to the side walls. But to do that, I have to extend the structure all the way to the side walls first...
