Last month dd and son-in-law decided to renovate the powder room. I don't have a before photo which is such a shame, as it's night and day to what it was. The floor was a beige and brown linoleum. The walls were beige and there was a cheap wooden and sink.
First thing they did was pull up the floor and get rid of the vanity. They painted the room a dark grey including the ceiling. and put in the white wainscotting at the bottom. The put in a pedestal sink and little mosaic tiles on the floor. Changed the light fixture and added new accessories. They figured all in all this cost them around $700.
This is the floor tile, sorry the photo turned on me. The floor vent is also a silver colour.
Dd is a huge fan of Young House Love and gets lots of ideas from them.
