Had similar situation in a rental once. Drilled several 3/8 holes and filled with Great Stuff can. Then used FlexSeal paint with a brush a couple coats.
Lasted from summer into winter when had more time to replace shower stall. May have lasted a lot longer!
The FlexSeal is really stinky, need good ventilation for a few days.
