Wet underfloor heating laid under wc position

[Jothetaxi]

Contractors have laid underfloor heating everywhere in a cloakroom and have screeded the floor. They have undertaken all the first fix for pipe work and cistern.

They have not considered there will be a floor standing toilet, as well as a floor standing vanity unit.

 

What are the option here? is this still acceptable?   Our architect has outlined it will be an issue drilling into the floor because of the pipework. 

 

Thank you.

Are you a new build? What did your plans say?

Alot of times the pan doesn't even need mechanically fixing down. I think resident plumber expert @Nickfromwales was just saying the other week he uses ct1 to stick his down. I didn't fix mine in last place. One was back to wall and stuck to wall, other was close coupled but fine stuck  ontop of floating floor

Just incase, we did that also. Was also concerned about drilling holes through tiles etc. 5 years later no issues.

As above. Bonding the WC pan down is my go-to. I just cut the screws down if they have decorative caps that are needed to blank off the holes, and bond those it too, for cosmetics.

 

The floor standing vanity will be fine with just a bit more CT1 behind each side, where it meets the wall, in conjunction with whatever other proprietary fixings are stated to use in the manufacturers installation instructions.

 

If you want any further advice for how to do that, have a search here for mine and others previous posts, or just reply here and we’ll talk you through it.
