Consider softening the square shape with a round basin and an interesting finish or colour. Also wall–hung vanities maximise the use of bathroom space.
All-in-one easy to use and streamlined units are best.
Internally rounded basins are becoming more popular, with the freestanding version best for smaller bathrooms.
The key to maintaining a bathroom that is both functional and attractive is storage. Minimalist free-standing storage and vanity units can be teamed with most bathroom features to great effect. One clever idea is to install shelving behind the vanity mirror.
