Hello Ice, We recently had a fair bit of tiling done, Porcelain floor tiles in the kitchen running in to the utility room and downstairs toilet, Cream in colour and impossible to keep clean for more than five minutes, The dust shows up very easily so my wife follows me around with a brush when I come in from the back, The darker they are the more obvious the dust is according to our tiler. We used ceramic for the bathroom and they look great , When you say durable we were told again by our tiler that if you were to drop something on a tile and it cracked you can see the reddish colour coming through on a ceramic but not on porcelain. If you dont have anything very heavy in your bathroom that would crack a tile on impact I would go with ceramic for a bathroom. Maybe straying away from the point a bit but our tiler who is an old friend told us to purchase our tiles wherever suited us but say no when asked if we want grout and adhesive with our tiles, If your tiler is as straight forward as ours he can save you a lot of money by you buying tiles only and getting the grout and adhesive himself.
