Style factor: The style factor of a white themed bathroom is no less, especially when a bit of black or grey is used. It is contemporary and yet stands the test of time.
Flexibility: A white themed bathroom lends itself to house accessories of most other colour combinations, whereas the same cannot be said about a bathroom with strong colours.
Bigger: Bathrooms are small places and the use of white colour makes the space look bigger.
Cleaner: When the upkeep is good, a white themed bathroom usually looks cleaner than multi-coloured cousins.
