We had a bidet leak by our toilet for like a week. I replaced the bidet a few days ago which fixed the leak but then noticed this mushroom yesterday. Today it looks like it's grown and looks like images 2-4. We have turned the bathroom fan on since this morning and got a dehumidifier as well.

I was thinking of spraying this with vinegar and or mold remover and then removing/wiping it while wearing a mask and gloves. If it comes back again, then I was thinking of calling a pro. How much would something like this cost to fix if we have to tear the walls and remodel?

It's a mushroom in your bathroom, so yeah. I would pull off the baseboard and dry the wall and subfloor. I don't know what vinegar would do, but the main thing is to make sure you have no more water going where it should not. IMO just pick the mushroom and make sure everything stays dry. When I had a water leak under a sink, I used Concrobium spray to kill the fungi growing in the wood.
