We like the mix of wood accessories with the white ceramic fixtures and tiles used in many bathrooms. We used a wooden mirror and bathroom faucet detail, as well as a tall, narrow wooden dresser (intended for use in a bedroom) for storage in our bathroom which really warms up the dark slate grey flooring and white fixtures. The recent posting of reader Keisha Kornbread's bathroom shows off a wooden spa bench in an all white minimal space to great effect.
But even if you don't want to add "furniture" to your bathroom, it is possible to add a bit of the texture and color of wood with a bath rug or mat made from wood. West Elm makes two options: A wood block rug (shown above) is $49. for the 2'x3' size. The Waterbury bath mat (right) is made from teak and is $79.
