Can a Acrylic bath tub crack be repaired

[Joe A M]

I have a small crack about 5/8" long on the floor of my acrylic bathtub . Can this be repaired? if so How do I do it.
Thanks for any help anyone can offer. new tub is not in the budget right now.

I believe it can. I had one repaired on our fiberglass enclosure but it wasn't DIY. There was a guy who specialized in such repairs, I found this out by talking to a local builder who apparently has a lot of these repairs done. this was some years ago, but he charged $75.

I tried to buy a cracked showerstall at BORG, for a project, but they told they had a guy who came round, and fixed any damaged ones, so you might check with local building supply places, as well.
FWIW, state inspector told me to cover my compressor with an upside down shower stall, to muffle noise-that was the project.

I fixed one once. But I was able to get underneath and brace the spot that originally cracked to prevent flexing. This is the first thing to consider- why and how did it crack?

Drilled a hole at each end of the crack to isolate it, used fiberglass bondo and feathered it out and painted it with epoxy paint. It looked good, but to be truthful- wouldn't want it in my house. A pro I'm sure could match it up much better.

Your local Plumbing Supply House should have the name(s) of a few guys that do the repairs. if the tub needs more support, and you have access to the floor from below, you can drill holes and spray foam to fill any voids. I drill extra holes to see how far the foam goes and also to give it a place to expand. Fill the tub with water so it won't lift the bottom up.

Yes it can be repaired, if you choose the right way.

 Well I don't know if I choose the right way or not but I did find a fiberglass tub repair kit at Menards. I gave it a try & seems like it should work ok.  We've been using the shower for 4 days now and it's not leaking. Hopefully the repair will last long term.

Yes, definitely it can get repaired, but for the perfect finish you may need to call some specialist in bathtub repairing, who knows everything about the bathtub in depth. As in our case the bathtub was getting worn out and the water releasing knob had got chocked so very first they tried to seal the pipeline and started working on the bathtub coating as to give a new glossy and shiny look to the tub. Likewise you can also try out contacting to such bathtub refinishing experts and get the work done in a perfect way.

Hmmmm....On the surface it starts to make sense.  However....I can't pin point it, something in this plan doesn't seem to jive.

I am in the process of re-finishing my bathroom.  It has a blue (blue!) 1950s bathtub.  Cast iron and porcelain. 

The options were fiberglass (not too durable and seemed to flex too much).

Acrylic, more expensive than fiberglass with an acrylic finish.

Cast iron, expensive and too heavy for me to do on my own.

Re-glaze with acrylic finish (professional).  The least expensive option, and I've been told that the applied acrylic finish will mimic the durability of an acrylic tub.

I settled on the re-glaze option.
