All you need to do is connect a standard garden hose to the plumbing located at the rear of the tiny house, just as you would with a caravan, and you're ready to go. Off-grid options are available with compostable toilets and water tanks. Chat to us about the best option for you. The sinks and shower will need to be plumbed into a septic tank. Please speak to your local plumber about this. Speak to us about your off-grid drainage solutions.
