Crack in one piece tub/shower.

[HeelSpur]

Got an old plastic one piece with a crack in it and have been watching do it yourself video's on youtube.
Anyone have any recommendations on a quick temporary fix til a new one can be installed?
Tub floor does have give to it so I reckon the insulation has shrunk so whatever I seal the crack with needs to give a little.

Silicone....the problem will return though if the bottom isn't brace properly.

By plastic you probably mean fiberglass and resin construction. V it out and dab some resin or epoxy with a few strands of FG or some cotton. Look at it very closely, the crack may extend further than what appears. It has to be bone dry. That will hold with some flex.

I used JB weld on mine and it held fine.

I was thinking JB weld for plastic or silicone. Probably be a couple months before a new one goes in. Lady down the road said she duct taped hers and it holds well and made it non skid at the same time. Thanks.

Depending on the size of the crack, super glue will work.
A couple years ago I discovered a 6-inch long hairline crack in the floor of my shower... super glue dots the full length of it. Not only didn't it grow any further, but I can't see where the crack was anymore.

^^^^^This. Place the new tub on a bed of mortar to eliminate the flex.

That happened to a friend of mine, he had a 10 inch crack that was leaking into his basement, i told him i will temporary fix it...I used a fiberglass kit i bought at the auto store, and it stopped the leak, and that was 10 years ago and he never got the tub replaced, and to this day its still in use...

I have had excellent results from JB WaterWeld. It dries white.

One of my rental properties had a hole punched in the shower surround.
The tenant was using the shower to rinse his surfboard and when it slipped out of his hand, the fin punched a hole through the plastic wall.

In some applications, drilling a tiny hole at the end of the crack will relieve the stress and prevent it from growing longer.

Don't use Silicone. Nothing will ever stick to it again.

Look up getting a small G-Flex kit from West System Epoxy. It will be your best bet at a long-term fix. Sure it will be a bit more expensive than superglue or JB, but replacing the whole one piece will be a lot more expensive!

Do it right - I think you will be impressed by the stuff.

I found a crack in mine when I bought my house. Epoxy cured it for awhile then it managed to pop loose so I went to the shop, grabbed some fiberglass mat and resin and went to town. Ugly as sin but it sure is functional!!
