Tiny house. Tinier bathroom.
There's no arguing that this bathroom is tiny. At about 36" wide and just under 8' long, there isn't much space, but there's enough to house a Separett composting toilet, a sink and a stand up shower. We use a small 10 gallon electric water heater, which, unlike the popular tankless water heaters, is able to keep up water temps in the colder months (as long as guests give it enough time to heat back up).
We don't want guests to worry about packing a bunch of toiletries, so we supply hand soap, shampoo, conditioner, body wash, cotton balls and lotion. We also supply clean towels and wash clothes. There is also a blow dryer in the cupboard for your convenience.
