Here you can see that we use our new Slim Porcelain Panels 71x35in with the thickness being only 6mm, with a gloss finish. We use 4 panels on a standard bathtub surround. We use grout that's similar to Epoxy grout. As well we have Slim Porcelain Tiles 16x32in with thickness of 5mm which are also used for Bathtub Surrounds and Kitchen Backsplashes. We install these in Manitoba, Saskatchewan, Alberta. If you have any questions please e-mail us: cpswpg@hotmail.com
