Are we just talking wall tiles here? What are you looking at for floor tiles? I'm thinking in terms of mixing gloss and matte in both rooms to tie them together and keep your customer happy but giving each bathroom its own character without being too different ................ if that makes sense.

Subway Tiles make great splach backs. Capping the subway tiles with an Atrim aluminium trim would add the finishing touch, nothing looks worse than the raw edge of tiles being exposed. (It just looks unfinished) You could use powdercoated white trim which would finish the tile while blending into the tiles or you could get a much bolder look by using the anodized matt silver which will match your grout and frame your splash back.

My vote is for matte as well. Especially in the bathroom. If the tiles are near the shower, the glossy ones seem to lose their shine to the soap scum and need constant cleaning like glass screens, whereas it doesn't seem to happen on the matte tiles which are quite easy to clean. The stove and the sink are really the only places needing a spashback in the kitchen and my vote would be for matte finish there, even if you use the same tiles in gloss every where else.

Hi there, tiles on the floor of a bedroom? It sounds a bit cold underfoot unless you are having underfloor heating installed, but then perhaps you are renovating in warmer climes than where I live! I would recommend going for a matte or satin finish in the bedroom as the gloss could look a little sterile.also If you have a connecting ensuite, you wouldnt want to run the risk of slipping on the floor if you have wet feet :o
