Whether you’re planning to go off-grid for environmental reasons, cost savings, or personal preference, building an off grid toilet system is a must for getting rid of human waste. Thankfully there are a number of off grid toilet solutions and ideas you can test out, this guide explores 21 innovative off the grid bathroom solutions that cater to various needs and preferences.

1. Compost Toilet

Compost toilet

Compost toilets are one of the most popular off-grid solutions. They use a dry composting method to turn waste into compost, which can be used to enrich soil.
