I repaired our oddball tub by welding the plastic and then adding a 
repair sheet sold just for that.
Prior to doing this I had tried some spray on sealer and I used the 
expanding foam under it, thinking to reinforce the pan.
I ended up with the foam pushing up a bubble under the tub as suggested
After that I decided to do a "proper repair" I pulled the tub out and 
cleared off all the foam that was above the ribbing under the tub. Then 
I cleaned out the areas under the break and welded them up and roughed 
up the area and added stainless wire between the ribs. Then filled those 
spots with epoxy. Then I added some marine plywood and then sheet foam 
until the bottom of the tub was flat and the weight was on the floor.

The reason for all this is because we have a short tub that they don't 
make a replacement for.
