It's not a bad match. It is a lot of brown tile in a small space to start, so I would not have done floor/ceiling there. And the vanity is very big and very dark for the size of the room. But as colors go, they go together well enough.
But you have installed it yes? So...I'd work on accents (hardware, towels, etc.) in bright contrast. Crisp white towel, tissue box on the vanity, architectural white light switch plates, etc. Definitely no gold.
And good lighting - nothing that casts a yellow shade, go with daylight type. You don't appear to have sconces - but I like the new style of bathroom mirrors with the built in LED framing that goes around about 1" in from the edge of the mirror?
