We like the USG DUROCK SHOWER SYSTEM
http://www.durockshowersystem.com/interactive-installation-guide.aspx
It is a complete system that leaves no room for installation errors that lead to leaks.
We use Durock on the walls, seam tape on all the joints and paint with Hydro Ban. Pour your mortar bed and let dry for 2 days and tile away.
We use the schluter system and durock backer board.
I live in southern california and have been setting tile for almost 28 years and always hot mop my showers.If a contractor or customer wants something else i usaully let them get someone else to do the job.
hot mop is the only way to go! quality never lets you down
We believe using the complete Noble system (including curb) is the most cost effective way to provide a permanently dry shower.
