I wanted to do the design of my en-suite bathroom myself because having re-fitted 2 previous bathrooms I knew what I wanted, and what I did not. The awful brown bathroom suite in a room with no window or door(!) has now been replaced with a sleek, semi-frameless 1100x900mm shower enclosure, statement basin, designer tap, LED lit cabinet and a new window and door. I got great advice from a local tiling showroom (http://www.decortiles.co.uk ) about the colour of tiles for such a small space. They dissuaded me from going for slate grey.
