Oh my, wow! That is a whole lot of look, haha! Yes, I think a clean slate is the way to go. I don't think I've ever seen dark green bath fixtures before. That shower is like a black hole!

Well, it was groovy at one time, just not this century.

It might be worth priming carefully and painting out the orange, to see what you really have. Not that I dislike orange, but right now you have so much of it!

If you do gut it, try to salvage the sink and tub. Someone will treasure them. I agree with jlc712 about the shower.
