I'd go with a deeper green... or bluish green

You've got plent of light with the board and batten.

sample a few to see what will work. Your black accents look great, but a bright brass would look great too.

or BM Bavarian Forest if you want to push it more blue, depending on the greens in the countertop.

Urban bronze or iron ore. Paint the ceiling too. Using one of these deep colors will highlight the green in your countertop and make it pop more than if you try to compliment it with another green.

I love the Bavarian Forest recommended by Lyn Nielson. I think, it would add a lot to your bathroom, which is very blah right now.

How about a fabulous wall paper like this Midsummer Fern from Graham and Brown? It would really make your dark hardware look great!

Yes, go with a dark green, striking! Or go a with an undertone of the counter.

Monitors are fickle, but here are a couple of ideas:

Consider a green with blue undertone. It could be a winner. This color scheme..

You have options

Thank you all for the suggestions - so many options! I think I like the bolder options, but I'm not sure I'm brave enough to go for it. I'll try and follow up once I get back to this room :)

A small bathroom is an excellent place to be brave and bold. They are great rooms to go outside of your comfort zone. Plus, guests really love going into a small room that is such a departure from the rest of your home. It is where I always experiment outside of my comfort zone and it pays off.

Well Hale navy would be bad........: (

I'd paper it in a heartbeat.

Either......

lol

Photos are NOT loading....of course, .It's HOUZZ.

Iron Ore to the rescue! Still contemplating the ceiling, but so much better already!

Love it!!
