Hi - If you want a response to this you'll need to post a little sketch of your room, showing all the things that need to be worked around - doorways, windows, radiators etc. :)

I agree with Amanda, add a drawing and we can help! Go for big tiles in a small room though, it will make it feel more spacious as you will have less grout lines...plus less grout lines means less maintenance! ;)

A wet room doesn't need to break your budget. We have kits including Tray, Drain and tanking starting from £195. Take a look at: https://www.wetrooms-online.com//wet-rooms-online-store/wet-room-kits/wetbase-standard-wet-room-kits
