For Master Bath - To add a little interest to the plain walls, add some 1" by 4" boards to one wall. Adds a little architecture to the room...a coastal cottage feel, no? :) Just glue and nail gun the boards on the wall (easy), then paint everything (possibly a cool white, like Dunn Edwards, Swiss Coffee) to expand, lighten, and freshen-up a small, windowless space.
shelving wrapped around the couch (doubles as a short console table) -- put together low shelves (bookcases): allows room for a bigger couch in the future. though i prefer a closed shelf for this one so it won't look clutter-ish.
