I guess they do things differently wherever you are. Your "waterproofing" behind the cement board isn't doing much good if it doesn't actually cover the studs which are still in plain view.

I didn't see this last post. I did cover the studs, the strip on the inside corner is a strip of 1/4" I decided to add after I had put up the felt. To shim it out a bit. I know it would have been better under the felt, but I figured as long as the actual studs were covered I would be ok.I did shim the back wall under the felt. The uncovered outside stud is an uncovered 1 1/2 " of a double which is actually outside of the tube.
