Tanking? No need for that my friend. Not with cement based grout.Thanks, never thought about the photos. I wanted a roman style bathtub. The idea
was to make it with the blocs and tank it with Ardex s7 then tile it. probably crazy I know,
wished I just bought a bath now. Well, it will be quite an excitement to rip it all out if I
don't succeed.
(Only kidding, make sure you tank it!)
