How a Dry Flush Toilet Works

A traditional toilet is not always the best answer when nature calls. For example, when your cabin has no running water. Fortunately, there are now other options that can do the job without the need for indoor plumbing. A dry flush toilet takes away the mess without any water and is even portable to provide more options. If you’re not familiar with dry flush toilets, here’s some information about how they work, along with some pros and cons to consider about dry flush toilets.

How Dry flush Toilets Work

Dry flush toilets look like a regular toilet and are about the same size, minus the water tank on the back. They have a lid and toilet seat. Inside the bowl looks like foil lining. Once you’ve done your business, a push of the flush button puts the space age machine into action. It’s a little hard to describe, but if you’ve ever used a Diaper Genie it will look familiar. The toilet first inflates the foil bag and then sucks it to the bottom, twisting it off to seal in the contents and the smells. When it is done twisting and pushing, you are left with a clean, dry foil-looking bag for the next use.

When you run low on bags you will see a red or blue stripe on the bags as a warning. Once your bags are gone you can replace the entire cartridge easily and without a mess by simply inserting a new one.

How to Install a Dry Flush Toilet

Dry flush toilets do not require any water hook-up so they can sit on any level surface where you choose to place it. This can be in a tiny home, an RV, a car, or a tent, as examples. The toilet is sturdy and able to hold up to 500 pounds. It can be mounted to the ground for added security if you choose. The dry flush toilet does not require any sort of venting so installation is basically just removing it from the box. At only 26 pounds, it truly is a portable option.

Powering Your Toilet

Plugging a cord into an outlet

The dry flush toilet is battery powered with a rechargeable battery that sits near the bottom of the toilet base. Although the battery will last for around 300 flushes, you can easily recharge it at any time by plugging it into a 120v outlet or using a solar option.

Dry Flush Toilet Pros

The dry flush toilet is a nice option when you don’t have running water. Although a little expensive for an emergency toilet, it is versatile and would store easily for that purchase.

Another benefit of the the waterless toilets is that they also do not use any chemicals like other toilets commonly used in RVs. Because you don’t have to worry about the septic system, you can use any type of toilet paper that you prefer.

The design is well-made and sturdy, plus there are no odors, no leaks, and no messy emptying process.

Dry Flush Toilet Cons

The bags of waste from the dry flush toilet are not currently biodegradable. In most areas, it is acceptable to throw them out with the regular garbage. However, if you don’t have garbage service you will find yourself hauling them off or burying them on your property.

The actual toilet costs less than a compostable or chemical option, but the long-term costs well exceed the other options after factoring in the frequent cost of replacement bags. At over $1 each, it’s better to limit uses if you plan to put a waterless toilet into service.
