Crack Along Edge of Shower

5 Replies

Hello BP Do It Yourselfers! 

The shower wall in one of my rental units has started to separate from the wall. See photos below (note they should be rotated 90 clockwise). How would you recommend I fix this? 

I was thinking about filling with composite sheet rock, waiting for it to dry, and re-sealing with latex caulk 


Filling the crap out of it with Gorilla glue, waiting for it to dry, and then re-sealing with latex caulk. 

Do either of those sound like a good idea? 

Thanks in advance for the help!


Just bumping this up. Any contractors experts in bathrooms that might be able to help?



I'm having trouble picturing it in my head from your pictures.  Is this a one piece shower surround, the kind you mount directly to the studs?  Or is this one of those cheap glue up shower panels that glues to a backer board?

@Randy Landman

I believe it is closer to the later. I didn't have it installed, but I think it was one of those new shower in a day installs. The ones where they just put a plastic tub over the old and then adhere the plastic to all the walls of the shower.

I'm just not sure what type of glue / epoxy I need to adhere to the plastic of the shower and the sheet rock of the wall. 

Thanks for the help!

How big is the gap? It is rather hard to visualize from just the closeups. Do you have a pic that is taken a little ways farther back so we can see the "big picture"?

If it isn't too big, you'll have better luck using a good caulk that will stretch a bit rather than packing drywall compound in it. The product "Big Stretch" comes to mind. You may be able to find a construction adhesive (make sure it is compatible with the plastic tub wall) that you could squeeze in the joint and then brace it with something to hold it against the wall until the glue sets. Alternately, if you have something solid behind it like a stud behind the drywall, you could predrill a couple holes and use a cabinet screw (exterior grade, we use GRK from Home Depot) to gently pull it back against the wall. Key word is "gently", you don't want to crack the shower. Then you may be able to cover it with a piece of trim or whatever if you don't like the looks of the screws.

Hopefully this helps...
