My parent's house was built in the mid 70's. It's a Bi-Level on a slab so there is no basement or crawlspace.

Downstairs is a small bathroom with s shower. The shower floor (I believe it's called the pan) has some cracks. A "handyman" "fixed" them with some waterproof paint like material. Well the "fix" is now gone.

Is there any way to permanently seal the cracks? They would prefer not to have to have a professional come in and replace the shower pan because that would require the removal of the sink and toilet to gain access.
