Celotex insulation

[ShaunCorbs]

Doing a bathroom atm, it's got a tiled floor I have a feeling there going to be a pita to come off, as you can see below is where I removed for the shower tray (level ax) and the screed is soft







Now one the question the gap between the levels are 2 3/4 inches (approx) I have two options

1 try and take the tiles of and self lev the floor 2-3mm then spark can put elec heat mat down (he's happy with no ins under) and self lev again to cover mat + 5mm

2 rip out screed and tiles and put 50 mm celotex ins down and self lev 8mm approx spark to lay mat then about another 8mm self lev

also another q does any one know if celotex would hold a 60 kg toilet + person (me don't think so, so would need a pad )

O and just to make things worse it's the only bog in the bungalow

thoughts ?

If you are going to finish with tiles why not use marmox, jacoboard, wedi etc. It comes in various thickness, or you can build up in Meyers. You can use flexi tile adhesive to stick it down, underfloor wire, self level and tile. Celotex is not structural and you would have fun fastening it down.

No vinyl floor and was thinking of just laying it down tight like they do for wet underfloor

this is the stuff I'm on about

self level it if its only 2-3 mm,cellotex would be a bodge

I would rip the lot out, then use 40mm marmox ufh, self level and tile to required height. this way would give you a level height finish to your adjoining room.

Fair enough lads (did email celotex and they said there product would be suitable) will look around

Looking online, Celotex FI5000 would be suitable but this starts at 75mm, too big for your needs.
You wont go wrong with marmox.
