Shower Window: Question about timelines

6 years ago

Hey all,

I’m remodeling my bathroom and am installing new tile around the tub, to the ceiling. I have everything stripped down to the studs and I’m ready to put up Durock 1/2” backer to prep for tiling. Here’s my problem:

I have a window in the shower that I need to replace. Tile will surround the window, with the sill/frame being PVC trim. I haven’t ordered the window yet, and it’s a 4 week lead time. Am I able to remove this old window, tape or seal it off from the exterior side, and do my tiling before installing the new window? Will any tile be damaged during installation? Without the window my project is at a standstill, and I want to keep moving to finish as efficiently as possible.

I have pictures I can post tomorrow to help with the dilemma. Thanks in advance!

What the frame thickness? I would imagine 3 1/4", and then your wall is 4 9/16" so you would need cement board returns which would need to be taped , as well as the window to cement board transition, then the whole enchilada covered with Aqua Defense. I do not know how it would possibly to do all of that after the tile was installed. Personally I would wait since you obviously cannot plan it out better at this point and this point of the waterproofing stage is crucial as you really do not want your exterior wall system getting water infiltration (insulation wet = mold = rot).

All the materials must be on site. The window must be installed right after demo of the old. You can’t properly install, or integrate the waterproofing to it if you tile first. What waterproofing system are you using?

You MUST have new the window installed as the waterproofing must be tied in to the new window and tied in extremely well at that. Please tell me it is vinyl? Also as LWO asked what waterproofing system will you be using? Would be a good idea to contact that manufacturer and get their recommendations on tying in the window to the shower waterproofing system.

Thanks for the advice, I’m using AquaDefense paint-on waterproofing. The current window is aluminum and I’m replacing it with vinyl. The previous contractor that did work in the house obviously cut a lot of corners. (I just bought this house as a foreclosure and I’m fixing up a lot of things).

Am I able to prime and waterproof the window frame and then tie the window waterproofing to the frame instead?

For theory sake, would the waterproofing system be the only thing that gets screwed up if someone were to do it this way?

I think I’ll go to the store today and see if I can buy a window that’s in stock instead of the 4 week lead time window! I also am remodeling the floor (previous contractor did a crappy job tiling and they’re popping up) so I can work on that while I wait for the window as well. Seems like there’s no getting around this error and i don’t want my haste to result in serious damage down the road.

could be done , methodically. Millworkman is correct the board returns need to be flashed/sealed to the window FRAME. your better off utilizing a waterproof foam board in the window jamb returns and seal the entire 1/2" of foam directly to A vinyl or fiberglass frame. I would strongly suggest all the trim be azek or similar and sealed to the waterproofing w/ hydroban sealant /kerdifix or similar NO NAILS THRU waterproofing. then abut tile to the azek leaving 1/8" gap minimum. and finish w/100% silicone.

thats how the pros do it. Smart build.
