    I have to fix a new toilet to my daughter's downstairs toilet.She has just had the floor retiled. The house has piped underfloor heating. I am just a bit concerned about screwing the pan to the floor and whether the pipes will be far enough down not to worry. The previous wc was plugged and screwed down in the normal way.Any thoughts please.

    Shouldn't be any pipes under the pan so check it first.

    Shouldn't but wouldn't trust somebody else.

    Drilled to wall and silicone to floor.

    How can I check it, the pipes are under a tiled floor so I can't see if there are any there or not?

    Turn it on, does it become warm in the area. If in doubt then don`t use screws however if the pan fixings use`s L brackets with horizontal screws I`ve seen blocks of wood stuck to the floor to replace the brackets. ;)

    Epoxy resin. Or change the toilet to a wall mounted toilet.

    Not easy to take out again if I epoxy it. Toilet already bought and wall mounting not possible anyway.

    I agree with simong and bogrodder; screw cistern to wall and then run a nice bead of silicone around base of pan (use leveling packers first to ensure no rocking of the pan - cut them off flush with the porcelain). I've done this many times, can easily take out in future if needed but is rock solid for normal use. DO NOT consider screwing into floor.

    If there is a toilet there already surely you should be fine? I personally wouldn’t be too worried if there was a toilet there already.

    I really wouldn't. The previous pan fix could easily have just been a lucky miss of the UFH. If you know it's there why would you risk it when other viable alternatives exist?

    You could switch on UFH and use your elbow, it's quite sensitive.. or is that for babies' baths?

    A joiner has put some boxing behind where the previous toilet was so the new fixings would be about 200mm away from the previous so I think it would be taking a big risk to drill new holes.
