Sometimes the bathroom gives you undesirable leakage and blockage. Generally containing a toilet, a sink (basin) and either a bathtub, a shower, or both. Bathrooms often have one or more towels bars or ring. Some bathrooms contain a bathroom cabinet for personal hygiene products and medicines, and drawers or shelves (sometimes in column form) for storing towels and other items. The design of a bathroom must account for the use of both hot and cold water, in significant quantities, for cleaning the body. The water is also used for moving solid and liquid human waste to a sewer or septic tank. Water may be splashed on the walls and floor, and hot humid air may cause condensation on cold surfaces.

Bathroom lighting should be uniform, bright and must minimize glare. For all the activities like shaving, showering, grooming etc. one must ensure equitable lighting across the entire bathroom space.
