I found a pink worm in my shower about 2 weeks ago and yesterday I found 3! My shower is in a corner and the worms are found in the place which mainly acumulates water and has a little black mold. How can I get rid of the worms? Cause they're freaking me out!

I would remove the worms then maybe bleach the mold. Try to get rid of the moisture. Perhaps you could take up Fishing, I'm sure the price for worms has gone up like everything else.
Do you have a bath exhaust fan or window?

Yes I do have the window and a fan but still its still moist

And you say you don't like Fishing.

No haha. I just want to get rid of them

You'll need to take it up if you don't solve the moisture problem in your shower stall. That is the cause of both the fungus and the worms. It's possible the pan under your shower has deteriorated and the shower is actually in contact with the ground.

So I should remove everything and fit in a new pan?

It's a bit more complicated than that. I'm going to refer your question to a home repair expert who can better explain.

What material was used to build your shower pan? The moisture problem must be improved with more evntilation.
