We don’t have a demo budget and are just going for paint right now. In 10-15 years we’ll do a demo but there isn’t anything functionally wrong with it right now except the peeling paint and some rusting on the hardware (esp. the towel bar which I might just remove). I’m just looking for something a little brighter. The tile is SUPER grouted in there...

I’m thinking maybe I should take it in a neautral “spa” direction since it seems like that’s the closest fit. I just need a different wall color (not sand or beige).

I might use the warm beach glass blue-green color that you have in in your accent tile..only make it deeper, somewhat darker color..such tile plays well either with colors drawn from it, where it blends(such as now)-or it needs something stronger next to it but still keeping same warmth of shade of a color chosen.

Would you consider this direction? Of coure one needs to make samples first etc. To see how looks in the space

I also think deeper warm blue-green like that will be a nice background for dark vanity. Will play well with gold too if you go forward with redoing the pulls etc.

The wall tile is fighting with everything else in the room, it looks like to me.

As Aprilneverends says going with the greenish glass color from your listetto might work. There is a lot of pink in the mosaic. Pink and green do go together. You could go very light bluish green gray.

here are 2 paint options I made. one is a gray/blueish green the other is a taupe/gray color, in my estimation.

original:

grayish greenish

taupe/gray:

here's a lighter version of your existing color:

I like all of the options everyone has listed. I really like lighter/brighter bathrooms but would consider doing a darker shade of the sea foam green tile, maybe as an accent wall though.
