Is UFH for bathrooms worth it?

True . Always best to blame the cat in my experience. Which reminds me , I should get a cat 

 

If you get a dog they'll eat it for you. The cat poo that is, not the cat.

@joe90 or @Bitpipe if you had to guess, how much height would you leave for the electric UFH and accompanying self levelling compound?

 

For me this would be on top of a screed over concrete. I'm guessing I need to allow 6mm for the electric UFH and self levelling combined, but would value your experiences there. That would mean on top of the screed I'd have roughly:

  • 6mm self levelling compound including electric UFH wires
  • 3mm tile grout
  • 6-12mm tiles

So up to 21mm.

Don't bother - you will be heating the screed and not the tiles. You need some sort of decent insulation under electric mat.

As per @PeterW you need some insulation under it or the screed/concrete will just suck the heat out of it, it’s not like UFH which heats the concrete slab like a huge storage heater. The online sellers of electric mat also sell the insulation sheets. With mine the elements were in a self levelling compound about 8mm thick then LVT.
