People can definitely remodel their bath in a weekend.
If your bath has an outdated medicine cabinet, consider replacing it with a simple, wood framed mirror. It's amazing what a difference this little change will make in the room. Then carry that wood theme even further to spice up the bath with the look of furniture. Add an armoire, a small cabinet for towels, an accent table or even a bookshelf. All these items will add a special touch and warm up your bath.
