Converting wetroom - access shower drain in floor

[jacko555]

Existing bathroom is a wetroom with wet underfloor heating and a wheelchair accessible large shower with a drain in the floor.

I want to remove the shower screens and put a freestanding bath here, sitting on top of the drain.

I need to somehow remove the drain cover and attach the waste from the bath to the waste pipe that must be under there, without compromising the wet underfloor heating.

I think i just need to go slow, drill, chisel, dig it out so I can solvent weld a bit of pipe, then, fill it in with cement.

Is there anything obvious I am missing, or, a simpler way to do this?

If it's an upstairs room, go from beneath, cut a hole in the ceiling.
If it's ground floor, rather you than me

Ohhhh cracking idea. Yes, upstairs. Much easier to try and push the whole thing up then dig it out.
Genius
