[upfront]

Thanks,
now on a different note, I found a drawing on a different thread. "New tub instalation" posted 02-08-2007. I tried to attach the drawing but i keep getting an error message."You are only allowed to post URLs to other sites after you have made 15 posts or more".
The diagram shows tile going down past the tub flange. What holds the grout in where the tile goes down past the backer? I have a new tub here, the flange is 1/4" thick, The backerboard is 1/2" thick. that leaves 1/4" space behind the tile, the grout will fall out.
