What is the OGO Compost Toilet?
The OGO Compost Toilet is a small, portable composting toilet that offers seamless separate liquid and solid waste. It's perfect for your tiny home, RV, boat, or off-grid lifestyle.
Every OGO Compost toilet is assembled by hand in the USA and is made of strong materials like polypropylene and HDPE that are easy to clean. The OGO Compost Toilet allows for 25-30 uses before emptying the urine bottle or solids bin. OGO provides the most features and tiny size to ensure an easy transition to going off-grid.
How does the OGO Composting Toilet Work?
The OGO Composting Toilet is simple to use and easy to install. The first step is to mix your medium, we highly recommend Coco Coir by OGO, in your solids bin. Mix with water and “fluff,” check your manual for details. Next, open the trap door by pulling straight on the pull handle; close using the same motion. Toilet paper can be discarded in the solids bin, we suggest single ply or biodegradable to prevent clumping. Press the button on the side and walk away. OGO will get to work, starting the compost process.
The OGO may look different, but with one of the largest urine bottle capacities and custom engineered bowl seats, we offer an easy to use product. Sit towards the back of the seat and relax. Our urine diversion technology helps keep liquid waste contained. Refer to your manual for full details.
How do you install the OGO Composting Toilet?
To install the OGO Composting Toilet, you'll want to make sure the vent is installed correctly.
First, locate a spot where you can connect your vent hose. You can use any exterior vent such as our Shell Vent (with an 1-1/4″ PVC pipe) to allow air to exhaust outside, each unit comes with 5-foot hose and a swivel vent to ensure it can be vented with any build. We can also offer custom hose lengths upon request.
OGO’s fan pulls moisture and odor from inside the toilet and pushes outside. We also offer Charcoal Filters which can vent solution without pipes or hoses!
OGO works on a 12V system. It comes with a power cable that you can plug into the power jack (back corner next to the venting T-Bar). The cable has two open leads where one end is marked positive. Plug your positive wire into the positive of your 12V system and the negative wire into your negative. If you have access to 110V (normal wall outlet) then we have another model that comes with a 110V power adapter.

Does the OGO work in a wet Bath?
The OGO works for wet baths, you will have to cover the top of the toilet, we suggest a plastic bag or OGO's wet bath cover. We also recommend that you install at the highest point in the shower or on a raised ledge. Water may collect towards the bottom.

Have to confess that it hasn’t been used yet. But, it fits perfectly where we installed it, and it was so easy to install, I was sure I missed something. We had a small technical issue, but the company took care of it fast.
The OGO has been a great addition to my tiny home. The OGO has clearly stood out as the most visually attractive option available, in my opinion. I’m impressed by this product. It's attractive, easy to use and clean, and serves its purpose well.
We very intentionally waited 3 months to write this review, and we’re glad that we did! If you’re committed to installing a composting toilet but stuck with whether to choose OGO vs Nature’s head, this should help. I will address the positives as well as the negatives and what was necessary to overcome them here. The biggest value-adds of the OGO are the motor driven agitator and the really attractive, smaller form factor. The hardest part is the learning curve that is inherent to dealing with your own waste – no different than any other composting toilet or even your first bad experience at the dump station.
To begin, installation was very easy. We had a Dometic macerating toilet in our 2018 Airstream Classic, which means we already had 12v wired to the toiler for the fan and motor in the OGO. Additionally, the macerating toilet drained out of the back into plumbing that was the same size as the vent tube for the OGO, so we’re able to vent into the black tank, which then vents through a pipe and out of the roof of the Airstream. If you choose to do the side vent offered as an option by OGO, be sure to put a very fine mesh over the vent outside your rig, as we have heard of others who had bugs come in the vent and do their thing in the solids bin. After setting up venting, we simply screwed the unit into the floor (it comes with 4 wood screws) and were good to go.
One concern for us was a reduction of comfort, as the Dometic macerating toilet was porcelain and overall very nice. Both my wife and I agree that the OGO is very comfortable and we’re happy to have made the change.
The solids bin is now in a place where it gives us no trouble whatsoever. We simply dump out the old mixture (choose your disposal method carefully and with respect for your environment) add 8 ounces of dry coco coir and a couple of cups of hot water (expands coir more effectively) to the bin around once per week. The used mixture comes out clean with very little smell and no trouble. Wear gloves if you like, but the process is very easy to do without coming into contact with any solids.
Here’s what NOT TO DO: At first, we added FAR too much liquid to the solids bin. As we learned, the mixture is intended to be rather dry. If you add more than 3 cups of water to the appropriate amount of coir (we added 6) you will create “compost soup.” Use your imagination, then imagine it leaking around the agitator seal and onto the floor. Not pretty. We promptly got in touch with Kevin (the owner, who has graciously worked through us and always sent us same-day replies… He has our name on speed dial at this point) who notified us that the seal is intended to handle a dryer mixture, but cannot handle that volume of water. If you do your research, you’ll find some individuals in forums saying that the side-entering agitator in Nature’s head makes more sense for this reason. Perhaps, but if you get your mixture correct, you’ll never have a problem.
The next adventure we had was that in adding too much water to our mixture, we over-stressed the gear box and caused a failure to the agitator. Kevin (ever the hero) mailed us a new gearbox promptly and shared how they’ve since increased the strength of their cogs to avoid this issue. No problems whatsoever. Again, we caused this failure due to improper use.
Liquids: One of the really attractive features of the OGO is that liquid waste is diverted to a separate container that can be emptied without having to mess with solids. The first iteration of the OGO had a seal on the liquids bin that had to be kept perfectly in place to ensure that no liquids could slosh out if you forgot to empty before driving/if you live on a boat, but Kevin (if for no other reason, we recommend this product simply because it has an amazing team behind it) let us know that they moved to 3-D printing a new seal that filled the space entirely and required no adjustment. This problem is sorted on ours and your unit. Otherwise, no issue with liquids. We’re very active and drink a lot of water, so we empty this once per 24 hours – takes less than 2 minutes.
Durability: We live in Alaska, so it’s not all smooth roads and easy going. All the components of the toilet have held up incredibly well so far, are easy to clean, and appear to have what it takes to last for years.
For the price, you’re getting solid engineering, peace of mind, and a really easy solution. Kevin and his team are working to make the product the best it can be, and will definitely take care of you if you have feedback along the way. The motor driven agitator works excellently and we still laugh at the line every time we go past the dump station. Make sure you know how to properly prepare your compost and you’ll be good to go. Highly recommend!
Better to have a separate toilet!
The patience to wait for the OGO has paid off in full for us. The Thetford chemical toilet has finally been replaced, as far as the OGO is concerned, the conversion was extremely easy: measure, stop, install, connect. The big “but” is only because we didn’t install a composting/separating toilet right away in 2015, but instead trusted in the old classic. Now we had to deal with the conversion as a receipt with more than eight holes from former screw connections in the shower walls, an unused hole in the floor and a useless, poorly insulated flap to the outside. So tip: go for a well thought-out, high-quality urine-diverting toilet like the OGO if you can design your motorhome cabin to a certain extent yourself or according to your own wishes. We have been using our OGO continuously for around two weeks and are extremely satisfied, the details are well thought out, the mechanics work, the technology works – everything is very simple, convenient and completely odorless, at most a pleasant smell of forest soil from the moist coconut substrate.
I just received my OGO composting toilet and until now I am impressed by the design, the simplicity of usage. It is not yet installed in my RV but soon it will. I am especially grateful for the service I got when buying, The courtesy and friendliness as well as the fast and uncomplicated service! All was perfect and I will definitely share more once installed! Thank you OGO Team.
