I've seen those mirror heaters in posh hotels. A lovely touch!
Meanwhile I just had my builder suggest to get my carpeting done AFTER my tiling (we're doing both post-handover). She said she had her carpets laid first (in her own house) and then the tiling, and there was tiling dust and grout and dirty boots all over her new carpet. I was very grateful for the advice because I would never really have consider the order of laying to be important.
