The term 'water closet' takes on a truer meaning in a piece like La Cabine by La Fonction and Line Art. A bedroom space can certainly benefit from a vanity setup and a small sink for personal grooming, and few designs would provide these features as effectively and beautifully as this surprising item of furniture.
When La Cabine is closed, it takes the look of a slatted oak wood cabinet that likely contains the inhabitant's clothing. However, when you open both doors, you'll discover a whole washing basin with a modern faucet, a generous mirror and plenty of storage in the form of drawers and shelving. A compact unit like this water closet would certainly supplement contemporary urban apartments with only a single bathroom.
