Repairing acrylic tub crack

I have to deal with one big jacuzzi type tubs. It has some small hairline cracks on the floor of it--the base surface you'd lie in. Pic attached.

It looks like acrylic or some similar plastic/vinyl material. I wanted to know if this can mean it will leak? (The material is somewhat thick I assume?)

If it can leak, how/would I patch or repair the cracks? Thanks!

I'm not the pro here. I was just looking over your problem. I've found many videos on you tube that illustrate/explain how to stop/repair cracks. They involve drilling holes, using repair epoxies and then sanding and buffing smooth.

I have to tell you.... I don't think it's something I'd attempt.

The other guys will stop thru. Maybe someone has some DIY experience in that repair.

Time for a new tub.
Main reason they crack is it was installed wrong when new.

I have had some tubs arrive new with cracks but that's shipping damage. Cracks after install and use especially in the bottom means it probably was installed without proper support underneath.

1. Repairing it is a job. If you work in a boat yard it's probably no big deal. Otherwise you'll have to buy some epoxies and other items in addition to learning how to properly use them. There are people/companies skilled in those sort of repairs. I've had tubs repaired under warranty and you truly cannot see where they made the repair.

2. Before repairing the crack I would gain access to the space underneath the tub. You may find that there is a space under the bottom of the tub with nothing supporting it. Every time someone uses the tub the bottom flexes under the weight and it eventually cracks. The bottom will need to be properly supported or you're likely to get more cracks in the future.
