A very simple porcelain tile in a color from the vanity and I like 12 x24 for both the floor and the shower walls

What does the balance of the bathroom look like? Materials used and there colors and patterns?

The bathroom's fully gutted. No walls, flooring or other material yet. That's what we're trying to decide now. I was thinking of going with simple white walls because the space is so small. We've only purchased this vanity and sink (a slightly longer version than the picture), a matching linen tower (the grey wood color) and bathroom hardware in chrome. We've also purchased a simple mirror with LED lighting all around.

I’m a big fan of white. Where u don’t have a large space, it’ll help ur eye move about the room, feeling more expansive.

Marvin, this vanity is from Vanico Maronyx. The base colour is called "urban gray" and the counter is "concrete".
