Dump (you did ask!)

It's very dated, and I would get rid of it in a remodel. It does have one feature going for it: it looks entirely waterproof...;-)

I don't know but it kind of reminds me of a 1950's space capsule-inspired design. I think it is cool and would resurface if I just wanted another 5 to 10 years out of it. If you want to spend your money on something more permanent, then look at a tearout.

If I kept it, I'd add a second shower curtain on the outside of the tub to hide it. Wouldn't have to be a waterproof one because you have to have that inside the tub, but could be something cloth and pretty.

Brass is back in style!

Depends on your budget and other needs for your home, but seems like it might be time to update.

Replace if budget allows. Hide with closed curtain if not.
