The most important light in the bathroom is the natural light. The natural light should be enough, for this purpose there should be a window in the bathroom and it should be in that direction from where maximum light can come in. The natural light is very useful in the daytime. But this natural light does not work in the night therefore artificial lights for bathroom are must.
For the sanitary ware go with wall-hung or standard close-coupled toilet and basin with pedestal with acute angles and a contemporary design. Abstract towel rails and wenge wall-hung furniture fit well in the fantasy bathroom, giving it that calm almost surreal look. The ultimate luxury in a fantasy bathroom would have to be a waterproof TV. You could even think of doubling the bathroom up as gym, complete with exercise bike and rowing machine.
