Tiny House Bathrooms

Tiny House Bathroom

One of the bigger tiny space design challenges tiny house owner-builders face are bathrooms. A typical small residential bathroom will measure 5′ x 9′, or 45 square feet. That’s too much space to use when the house is just 120 square foot tiny house.

In a tiny house you’ll find normal flush toilets, RV toilets, commercial composting toilets, incinerating toilets, and lots of Lovable Loos (sawdust toilets). Sometimes the shower shares the same space with the toilet – a wet bath – other times it’s curtained-off. Sinks seem to be optional when folks are comfortable using the kitchen sink – but others prefer a tiny dedicated sink in the bathroom.

    In the last picture, how does one turn the water on/off on that toilet top sink?

  2. I dont think you do. It runs when the tank is filling so no water is wasted – you’re just using it as it fills the tank.

    Ah, so good if you only wash your hands after using the toilet, bad if want to wash your face or brush your teeth without flushing.
