Crack in fiberglass shower

honestly, that's not a good situation. is it on slab? Fiberglass shower manufacturers patch them but that's on the floor and it has texture. plus like you said it feels like it's not supported so the repair will be under a lot of stress.

I hate to tell you but the proper fix would be to replace it

If it's not on a slab, i highly doubt you don't have rot issues below.

The good news is it's not terribly hard to tear out a shower and install a new one.

good luck.

shite man, I don’t know what to tell you. I would contact the manufacturer and explain the issue to them. They have repair guys that fix cracks. We had a hairline crack in one of the walls of a new shower once and they sent a repair guy to fix it good as new. But I think your circumstance is a bit more extreme.

Which bathroom? If it's one that will get any reasonable use, I'd rip it and replace. As others have said not terribly difficult to do. Not a bad time to tile it if you think you'll want that at some point. If not, with it being so new, you should be able to find the same size insert to replace.

When installed the plumber should have put something under the shower, like drywall mud to prevent the floor from flexing

As said it likely cracked due to not being supported, so I'd cut a big enough hole out of that to where you can put a piece of wood under it to support it. Then do a fiberglass repair from there.

It seems to be kind of a "soft" place where its gently sloping toward the drain. I'm guessing the foam didn't make it there.

Think I will try to make a small hole, squirt some foam in, patch it, then see what happens. Can always replace if it doesnt work.

Should have been noted in pre-inspection and had previous owners fix as a condition on the sell.

I got in contact with the owner, he's going to have someone professionally fix it.

I have a corner bench left to install still, but not sure we actually want it.

Yes you want it!

Thanks. If you did do it yourself, give yourself about a full week unless you can focus on it for 10 hours a day. I though the tiling would go much quicker than it did. You can save a day by skipping the niche, but I love having it.

The estimates I got to have a pro do it were $650 for demo and then another %5300 to do the install (glass not included), and about a week from start to finish. I used the same Kerdi system they were going to use for waterproofing, pan, drain, etc.

It was a learning experience and tedious for sure, but I'm glad I did it myself. I have two more bathrooms left to redo now

To be safe epoxy it just mix a epoxy and fill it in with a squeegee like you would use doing body filler. That protects you from shower leaking and Damaging your home. That buys you time to get estimates and a solution. If you have access to the underside glass that thing up and go!
