If anyone is interested in fitting 15sqm of marble in a hall through to kitchen including warm up electric underfloor heating, please get in touch. I'm in Whitstable, Kent
Was thinking of doing the it myself, but it's probably a bit too much for a first time tiling job!
Floor is a mix of concrete, timber in the kitchen and floor boards in the hall. All seem pretty solid. I was going to use 6mm warm insulation boards over the whole area.
If you need any further info please let me know.
