I'm doing a bathroom and would like to put one of those thin electric heating mats under the floor. The floor is going to be vinyl with integrated underlay (William Stone Silver SPC from Wickes) on a concrete slab. I don't want to increase the floor level compared to the other rooms much, so I was hoping to get away without burying the mats in screed of any sort. Ideally just a DPC, thin insulation (5 mm Diall polystyrene?), the heating mat, and the floor (6mm including the underlay). Is that going to work? Can I put the heating straight on top of the PS underlay? Can I put the vinyl floor straight on top of the heating?
Wherever I look on the internet, I find bathroom heating always in a layer of self-levelling compound or under tile adhesive. I know the vinyl flooring isn't exactly mainstream, but I can't believe nobody has done this before... Thanks in advance!
