your best bet is to use a sprayer

I always use a high quality sash brush, like Wooster, or Purdy. They are more expensive then some others, but it is worth it and the brush will last. The sash brush is tapered and allows you to control the flow of the paint. Here is a picture of the bead board in my kitchen. It is similar to yours except it's 5 1/2 feet tall.

I think its a duravit mirror (with the lighting as part of the mirror)

Thank you!

Martha Stewart's Magnetite is a similar charcoal gray.

Try Creek Bend 790F-4 by Behr.

It's a bit hard to see in the photo. Not sure what that is made of, but it is lovely.

You can find vintage-style pedestals just like that one at www.vintagetub.com. They are one of my favorite online retailers - have bought stuff for almost all of my projects from them and have never had an issue.

SW6239 Upward by Sherwin Williams is similar:

This is not the same mirror but it has integrated lighting- http://www.qualitybath.com/product~name~Electric%2BMirror%2BASC%252D19%252E25x40%252E00~ID~130584.htm. Electric Mirror makes a few mirrors and medicine cabinets with lighting.

Benjamin Moore has a color called Chelsea Gray that's very similar.
