One of the bigger tiny space design difficulties tiny home owner-builders face are bathrooms. A typical small residential bathroom will measure 5′ x 9′, or 45 square feet. This is too much space to use if the home is just 120 square foot tiny home.
In a tiny home you will find regular flush toilets, RV bathrooms, industrial composting toilets, incinerating toilets, and lots of Lovable Loos (sawdust bathrooms ). Sometimes the shower stocks the specific same space with the bathroom — a moist tub — other times it is curtained-off. Sinks seem to be optional when folks are familiar with all the kitchen sink — though others prefer a tiny dedicated spout in the bathroom.
