We have planned a T-wall for our bathroom. On the long side (2.20 m (7 ft 3 in)), the washbasins will be installed. According to the general contractor contract, a drywall frame wall is planned. In the drawings (2D), only the total wall thickness of 20 cm (8 inches) is indicated.

We had an on-site meeting today regarding the drywall partitions. When the T-wall was mentioned, the site manager said that the wall must be floor-to-ceiling with a thickness of 20 cm (8 inches) for stability reasons. Additionally, he said it is "just" a drywall partition with metal studs and plasterboard (I hope I understood this correctly, sorry, I’m not an expert). He also mentioned that mirror cabinets cannot be mounted on this wall anyway.

We are now a bit surprised because that sounds somewhat questionable. No one really thinks about this when planning a bathroom during a house purchase.

Since the space between the washbasins and the wall behind them is not very generous, we do not want an additional drywall frame in front of the drywall partition.

What I don’t understand: the area above the washbasins doesn’t need to be as wide since no pipes or other installations run there anymore.

Our ideal solution would be: a floor-to-ceiling T-wall. Above the washbasins, a recess of 10 cm (4 inches) to create a shelf. From there up to the ceiling, the wall would only be 10 cm (4 inches) thick. We would only install a mirror and lighting on this thinner section. Since we already have storage space with the shelf, this would also make the T-wall look more open and less massive. What is the professional opinion on this? There is a meeting scheduled with the drywall installer. I wanted to ask in advance what might be possible so I can also gather other opinions. Do you see any problems with my plan? Possibly additional costs, and if so, what would cause them?
