A friend of mine wants to change his cloakroom toilet into a shower.
The existing toilet pan waste exits vertically downwards into the floor, in almost exactly the same place I'd be fitting the shower tray. Which is handy.
Once I remove the toilet and it's pipe work I am left with the mouth of the sewer at floor level - like a big round hole in the floor. It's an old ceramic waste. So if you can imagine it, I'm left with the mouth of a waste pipe pointing straight up, at floor level.
As it happens, it's almost exactly where then shower trap will exit - so my question is, whats the best way to interface the shower trap to the existing waste pipe?
