The east portion of the house is best for constructing a bathroom. The morning rays of the Sun are believed to be extremely beneficial for health, hence proper windows (of course with due provision for privacy) should be provided in the bathroom. The slope of the bathroom floor should be towards north and east so water drains to the north-east side of the bathroom.

A geyser can be installed in south-east of the bathroom. Taps and shower can be in north so the water drains to the north-east. Bath tub can be on the west side with head-side in south. Avoid a door on the south-west of bathroom. A washing machine can be placed in the northwest or southeast portion of the bathroom.
