I'm quite lucky that we have quite a large bathroom for over here. There all normally so small in older homes! I have a a lot of space to fill and was only going to use the tiles in the bath and on the floor. I find fully tiled bathrooms very very confining. White wall for the rest, apparently, according to the design guru. But it's ok, I've been told when it comes time to decorate the garage I can have whatever I want!!!!

try going to Hamilton Parker on Lenard ave. off 670 it is in downtown area and will give you great ideas.

I think, like you said, due to the fact that there's a larger space when it comes to the hotel lobbies is the reason as to why it works. I think that no matter what you put on the walls (whether it be concrete or marble) will result in tiles not working out. The industrial look tends to be exposed brickwork anyway, or cream or white colours so maybe that's an option you could look into. What did you end up doing?

Hope post shows, got some weird error message
