The use of reclaimed desks and drawer units in bathrooms is a great idea. With all of the tiling and white porcelain bathrooms can look rather cold and clinical. An old piece of furniture used like the one below to mount a counter top wash basin and taps can add a much needed warm lived in feel to a bathroom.
Admittedly it works better in a larger well lit bathroom. You wouldn’t want to try to cram something like this into the average small London Bathroom.
