Re: Shower tile chocies porcelain vs. ceramic & tile size
Generally speaking, porcelain tile is not glazed but very hard. requires proper sealing, and care must be taken not to get the grout into the pores of the tile. I believe you would find it a little more difficult to to care for properly. Ceramic has a non porous surface and is easier to clean.
