I'm trying to help my parent's out and I have zero bathtub experience.
This is a jacuzzi tub that's approx 15-20 years old. Everything works fine except as long as my parents have owned the house (about 8 years), the tub has never had a proper drain plug. They've always used that plastic piece you slap over the drain and that stops the water.
Mom wants to replace the drain with a lever type deal. Looking at the tub, I'd likely have to pull the whole dang tub out to replace a drain. There's zero room to work off the access panel, even if I cut the drywall out.
But I was looking, there appears to be a threaded hole in the drain. I was wondering, was this a plug of some sort? Can someone give me a name or description of what I'm looking for? l What are my options going from here?
Some pictures. Sorry they're so crappy.
