Things to Consider When Buying an Off-Grid Toilet

A well-made, well-used waterless toilet can turn your waste into manure set for ultimate use in your orchard.

A waterless toilet will also help conserve a significant quantity of water as well as save up some precious dollars if you are on limited or metered water supply.

Unlike the conventional loos, the waterless toilets do require more care and could be very perilous if they are not adequately cared for.

Below are few things to consider, before you buy an off-grid toilet.

Legal Requirements

It will be very thoughtful, if you review the local laws in your location, before making any purchase. Regrettably, waterless toilets are comparatively new and uncommon. Most states and municipalities haven’t made updates on laws guiding and governing hygienically-treated human waste. You could get persecuted or even fined for using a waterless toilet.

Ensure, to double-check with the local authority before you buy one. Normally, if you are in a rural area with an ample amount of land you need not worry. These are made for rural use and cabins. However, most urban and suburban areas won’t permit such, you could imagine the reaction from your neighbor if they find out you are composting feces in your backyard.


Ensure to adequately review the dimension of your desired toilet, and compare them with your available space. Because they do not require piping, they have a larger footprint compared to your conventional loo. For moving homes like trailers, tiny houses, and RVs space is a valuable resource.

Capacity and Maintenance

Some waterless toilet might seem easy to use while others may require you to carefully study the manual to avoid worst-case scenarios. Your attitude towards your toilet waste and byproducts should be considered.

Some loos will require being emptied more frequently than others. You will also have to consider your family size and how long you intend using it. Figure out the right approach that best suits your lifestyle and personal preference.

Availability of Repair Parts

You need to know if the repair parts are available in your country or location. Ensure that your toilets model parts can be easily replaced if broken or spoilt when picking your waterless toilet.

How to Get Rid of the Solid Waste

You need to think carefully about how to get rid of the solid waste because human waste can pollute the environment and make people sick. Ensure to have a sizable compost bin, preferably two compost bin – I always go for the rotating bins. Select a bin sealed enough to prevent leaching of liquid on the ground but not airtight. It takes about a year or more for one bin to get full (depending on the number of users), start using the second bin if the first get filled. When the second bin is full, the contents of the first can be used for manure on non-edible plants.
