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 north-west or south-east portion of the bathroom.
