We have an under-stairs toilet that we are replacing. The toilet was quite old, so the drain was 20cm from the wall. Apparently newer toilets require the drain to be pretty much flush with the wall, so we need to put a stud wall in place. It's such a small wall (1.3m high by 0.9m wide) that I don't really want to get a carpenter out to do it.
I've read up on stud walls and the advice is to attach it to the joists above. In this case there is just a plaster ceiling and the stairs above. I don't really want to attach it to the stairs (imagine if the nails / screws went through!) and I think the plasterboard ceiling probably isn't sturdy enough.
So, a few questions
- What's the best way to attach the top horizontal wooden stud? I'm wondering if no more nails will suffice onto the ceiling plaster if the rest of the frame is well secured.
- How many (if any) vertical and horizontal studs/noggins do I need for a small wall like this, considering I need to run some pipes through it and potentially hang the toilet cistern on it. I'm thinking maybe one vertical and one horizontal?
- Any other advice?!
As ever, all advice welcomed :)
