   The installation instructions for American Standard tubs would have you lap the backer over the tub flange after fastening the flange to the studs. This makes sense, as it better assures water tightness than stopping short of the flange. In my own bathroom, there wasn't a need to shim out the studs, as the flange was pretty thin.

   *Lap that dude!!and caulk it BEFORE you tile and after. and caulk the corners, and tape and thinset the joints. Water will get into every opening you leave for it and destroy any materials that are not resistant to rot. You can also take a grinder and dado the bottom edge of the backer to allow for the lip. And if you want to be really anal, which I believe is better in the case of moisture barriers, put a bead of caulk into the corner of the lip, before you set the backer onto the tub.trying to stay dry..Scott

   *It's often easier to just recess the tub into the studs when it is being installed. Just a few cuts with a sharp chisel where the flange will go and you're in business!

   A question on the installation of tile backer. Should it be lapped over the edge of the tube and thus require shimming out the studs or should it stop at the top of the rim. I've seen both and wondered is there is any andvantage to one over the other. Thanks
