I assume you're being a little tongue in cheek here. If that isn't the case whilst I trust a professional's opinion, the subcontractor they got to do the bathroom tiles did a brilliant job. Solid adhesive bed and both floor and wall tiles all flat. His rate was 50/m2. I also asked an acquaintance who renovates homes to sell as a living what his tiler charges and he said around 55/m2. Of course I asked him if his tiler could do my job but he said no. The only place I enquired that charged £80/m2 was stone interiors who did my kitchen surface which cost a fortune
