The Bathroom is a home extension in Harvest Moon 64. It can be purchased from the Head Carpenter by visiting his shop in the Carpenters' Clearing. The player must have 3000G and 300 Lumber chopped and in the storage bin when the Head Carpenter comes for the appraisal.
The bathroom contains a hot tub and a toilet. Each can be used once a day to restore fatigue and prevent sickness.
