I have a fiberglass shower leak drain leak. It is caused by the fiberglass cracking around the drain. I need to confirm my process for fixing this problem.
1. Remove old drain. It is a metal with a nut on the bottom. Can't unscrew it because the drain is so loose that it turns in the drain opening so I will cut it out.
2. Repair the fiberglass opening either with a kit or get a professional to do it?
3. Put new drain in probably a Wingtite?
4. The drain problem was caused by faulty installation of the shower, no support. To support the drain and shower I plan on using insulation foam since it would be difficult(tight space) to support with wood structure or concrete?

Anyone see any problems with process?
Thanks

I'm agreeing with everything except using foam to bed the shower floor. Since foam is mostly air it will not give the support needed. Isn't there something you could shore up the shower floor with that would give it more support? If it's the same foam insulation that I used to caulk my wall AC with then you can push it in with your finger, think what the weight of a 180 pound guy stepping on it will do? I would really look for something more substantial to bed the shower floor with. Regards, Tom

Thanks,
I only have a 6" opening to try and pour or stick something between the subflooring and the shower bottom. I could cut small 2x4 blocks and force them between shower bottom and subfloor?

Anything would be better then foam. I could puddle mortar or patching cement in a 6' opening. It would be tight and take a while but unless I'm missing something it could be done. All you'd have to do, if you can get your hand on there, is keep shoving cement or mortar through the opening until you have built up support pads. Regards, tom
