If you despair over the half-bath, and have concluded that there is nothing that can be done to make it desirable, think again!
There is a lot that can be done with tile – use the small wall behind the toilet as a tiled accent wall. Dramatic patterns will take your eye off the dimensions, and direct it to the colors and pattern.
Mirrors are always a good way to make a room seem, well, roomier. How about compact fixtures as well? One of the compact toilet designs can give you inches of space, and in that tiny bath, that means a lot.
The lighting you choose can make a marked improvement as well. Include mood lighting with warm light wall sconces and a brighter functional light with cooler bulbs that will brighten up the room.
