Is it possible to fasten door moulding over Durock? I’m building a new bathroom. One side of the neo-angle shower ends about 5 inches from the door opening. My initial thought was to extend the Durock on that wall past the shower edge to the door opening. But then will I be able to nail the door trim moulding (3″ wide) over it? Or maybe glue it? I plan to have the door trim butt up against the tile, so there won’t be any painted bit of wall.
The alternative is to end the Durock at the shower’s edge ( just past the inside of the shower pan) and then have a 5″ wide vertical strip of drywall between it and the door opening. There would be solid backing for the drywall/Durock transition, since there’s a stud there to provide a nailing surface for the shower enclosure frame.
Thanks for any suggestions and recommendations.

Ending durock "just past the inside of the shower pan" is at a critical area of both the pan liner and possible shower door. I'd go behind the trim and spot glue to the durock, nail off on the jamb.
Trim over Durock
Hi Lisa. I've been a tile installer for 19 years. I agree that the Durock should be extended behind the door trim. This will eliminate the problems from moisture present (gypsum will disintegrate, mold). Also, whether hand nailing or gun nailing, you should have no problem nailing through Durock. Unless it is totally sealed off with a membrane, gypsum drywall in a shower assembly is just a ticking time-bomb of trouble! Hope this helps!

re: Trim over Durock
Thanks Jjj and Calvin for your very helpful advice. I'll go ahead and extend the cbu all the way to the doorway.
BTW, the Durock I'm using is the NextGen stuff, not the original. I just hung it yesterday and was surprised by it's lack of stiffness at the seams (where two panels meet) between the studs. You can press on it and it flexes a bit. The studs are 12" OC and 16" OC. This worries me. So does the fact the NextGen product has only been out a year and isn't time tested yet. I'm wondering if it would be a good idea to put add'l backing behind the seam. What's been the experience of you tile guys?

You'll be applying mesh tape over that seam, bedding it in the thinset. I don't know that I have ever given the seam between studs a good push, but I'm thinking your movement won't be a problem. If you think so, then for sure back it up.
No direct experience with the board you call the next generation
