I could not find where to start a new thread, so hope you don't mind me posting here.
We are going to tile the bathroom walls. Just a few questions.
We want to do away with the skirting board, would this look okay tiled to the floor?
We have a very small bathroom so are doing away with the bath and putting in a shower cubicle. I have heard say that the bigger the tiles, the bigger it makes the room look. What do you think?
I am going for pure white gloss tiles and was going to use a border as relief but wondered if it would be better without to make the space look bigger?
