We're sorry we didn't remember this little gem during bathroom month, but from a house tour ages ago comes this amazing hand painted flower mural in a classic pink and yellow tiled bathroom:
Covering the walls and ceiling, Mara handpainted these flowers in a complementary palette and instantly updated the feeling of waht could be a seriously outdated bathroom. Instead all of the charm of the bathroom's original intention remains while the bold painting adds some newer life. Maybe a bit involved for a renter (that has permission to paint) but something similar could be done with decals or just painted on a smaller scale.
