I have a Hot Springs Grandee that has a crack as seen in the pictures below. I am wondering if it is repairable and if so what is recommended to do the repair. I believe it is acrylic but not sure if it is fiberglass backed or not. I believe the tub was hit somehow when empty and that caused the crack. I saw the tub one day and don't think it had a crack and then 2 days later it had the crack. it was empty the entire time but did have another tub on top of it. Should be 3 pictures. One of the top, one from a distance so you can see where the crack is, and then one that is a little more close up on the inside.
