I had same exact(or almost same exact) color on the walls in our previous home kids/guest bath, and used this shower curtain-tiers range from very very pale yellowish white to deeper turquoise

(sorry cropped the pic since at that time my then 15 year old daughter used to have an abnormal amount of beauty stuff on the countertop..))

it's from Anthropologie-they don't carry it anymore but sometimes you can find it on eBay

main idea though-you find the accents that have warm blue, either by itself or with your creamy white together. It can have other colors/shades as well.

So..shower curtain, towels..and find, say, a nice ceramic mug for toothbrushes etc..they don't have to be in this ready made bathroom ones. Pottery and ceramics adds warmth.

You can put a non-precious art you love on the walls. Something like oil maybe. You can get it in vintage shop, estate sale, flea market..

That's the one I found-it was born to be there, and we loved it..when we moved we made it a part of collection of sea art that my DS likes..so now it lives in his room

btw you can get a small plant too:)

treat it like it's a room..which it is, to a degree

and congrats on your remodeled bathroom!

The brown floor calls for blue-green accents. That color is everywhere in bathroom accessories. Personally I'd use a straight shower curtain because it looks like the toilet crowds the shower. Edit: Now I see the shower curtain reflected in the mirror. That's perfect!

I would get a decorative mirror as my art and hang it over the sink. I'd also have the electrician move the light box so it's centered over the sink and change it to a two-light fixture. That four-light fixture is out of proportion for the room/vanity and throws the whole room off. Then you might have room for a small metal towel shelf for over the toilet. Put a towel hook on the wall between the shower and door. Put a hand towel bar on the wall where the mirror is. I have this cute 8" bar from Ginger.

I love the vanity but I'm confused by the mirror on the side wall. Are you going to put a mirror under the light too? It looks like a mirror under the light is going to really show the light is off centered. Have you considered moving it?
