Hole under shower and mice
How have you closed up the giant hole under the shower to prevent mice? I can’t believe they cut such a large hole under the shower for the drain pipe. Due to mice, we started hunting for the entry...

If they can get up through the floor, guaranteed they'll have been nesting and playing in the underbelly space and making a mess of the insulation or damaging wiring and other things. Maybe the underbelly material should be pulled down for inspection.
Trying to reach under a shower can be difficult depending on if you have a walk-in shower or tub/shower combo and how large the access opening is. I sealed up all of the holes in our floor (and there were lots). Worst was the duct from the furnace went down into the underbelly and where they hacked a hole about 8x8". I used a piece of plywood to patch that one and foam elsewhere except under the shower I had to use Tuck tape due to restricted access.
A piece of sheet metal is a good idea or a piece of plywood (1/4" - 1/2") should also work. Could glue either down with PL400 construction adhesive. If the hole needs to be an oblong/oval shape, you could cut the metal or plywood as close as you can against the P-trap and then use spray foam to finish it off. If you have enough clearance, you might be able to use a stubby screwdriver to screw the patch in place.
Remember, you should be able to get the P-trap out some day. Maybe just use a few small dolops of glue so you can use a chisel or screwdriver to get the patch off if ever needed. If you have enough clearance, you might be able to use a stubby screwdriver to screw the patch in place.
Mice can squeeze through a hole as small as the size of a dime so you want to seal it well. I'd also seal up any other holes you can find in the floor.
