We're having trouble deciding what kind of material to use for our raised bond beam and spa. We want something to match our ivory travertine coping, but we're not all the happy with the waterline tiles that are made to imitate the look of the travertine. Has anyone ever seen basic 4x4 or 2x2 tumbled travertine tile that is typically used for kitchen backsplash, used for a raised bond beam or spa. This would not be used at the waterline, but it would certainly get wet often with splashing and the spa spillover.
We are going to have glass tile at waterline. I'm thinking I would have to use the same method on the travertine. waterseal/membrane, mortar, thin set, travertine. Would this be significantly different from the tumbled travertine that is being used for coping? Any big risk with doing this?
