I cleaned-up, painted and organized the large built-in shelves behind the bathroom door:
I also painted the oak vanity and replaced the hardware. I chose Sico melamine cabinet paint in pale grey, which actually has a green-grey hue.
In the meantime, I also painted the small built-in shelves next to the vanity in the same green-grey colour (obviously I'm still working on populating it with our things):
I love these cute little jars I found at Value Village for just 70 cents each.
As you can see, there's still lots to do, but we're getting there, bit by bit. I'm still trying to figure out a colour for the walls, so don't hestiate to leave your suggestions in the comments!
