Cracked Shower Floor

My fiberglass show pan on my 1969 Avion was cracked. It was very thin and had support on the bottom, but it was too thin. I removed the pan and had it reinforced on the bottom and encased the bottom in fiberglass. I then had it painted with a decent color. It certainly is strong now, and not much heavier than it was originally.

Excellent repair idea on a fiberglass pan. Trouble is, for many years now, showers are made of Vitron molded plastic. I think that is what the OP has.
The repair I did was in my '87 30' Award Columbia TT 20 years ago. They were notorious for soft delaminating floors (another repair story, that turned out well) and lightweight builds which came to haunt me in the shower pan.

Be sure to drill a small hole at each end of the crack to keep the crack from getting longer.

I supported my cracked pan using Great Stuff low expansion foam . find it in any building supply. Devcon Plastic Welder epoxy & fiberglass window screen fixed the crack, Rust Oleum acrylic epoxy tub refinish paint made all look like new.
Good Luck!

Brilliant minds.... yours, not mine.

Happy trails,

That said, blow in foam would insulate and support. Service down the road might be a problem though.

Also, bear in mind that the only structural support under the pan is the drain pipe, which is why it cracked in the first place. If you can, shove some 2x4's and shims under it, if accessable through a hatch door. Then repair as described. If you need to replace the pan, it's fairly simple. Still provide support under the pan.

Good advice. I would replace the pan and give it proper support while it is out. My pan was not supported at all along one side.

We have used this kit on two different tubs. Works well, easy to apply and inexpensive.
