Before: Too Purple and Young
First, she created a board-and-batten look by nailing up medium-density fiberboard (MDF) strips spaced 10 inches apart, then used 5-inch strips of the same material to replace the room's wimpy baseboards. When she couldn't find mirrors with the look she wanted, Diane framed the existing ones with MDF and crown molding. She caulked all the seams where the boards meet the walls, re-primed everything with a formula made to resist moisture, then finished it all in satin white; she painted the rest of the walls to match the tan tub/shower insert.
Shown: Vivid violet walls were the only uplifting note in this plain space.
