Composting toilet comparison

Let’s get into the details and let you see some of these bad boys in action!

1. Most Residential Feel: Separett Villa Composting Toilet

The Separett Villa is a waterless, urine-diverting composting toilet that operates on AC and DC power. It comes with a single-speed fan and all the necessary parts for venting and draining.

It doesn’t have a liquid waste tank as it diverts liquids to a holding tank or greywater system. The solid waste is collected in a compostable bag.

Key Benefits

Solid Capacity: 60-80 uses – About 2-3 weeks with four people

Liquid Capacity: Unlimited!


  • It uses composting bags, so there is no need to empty and clean a solid compartment.
  • Similar size to residential toilet
  • There is no need to empty the urine container!


  • Requires liquid drain hose
  • Have to buy composting bags

Power: 12-Volt for Fan

Check Price –> Amazon

My Thoughts

The Separett is cool with its residential vibes. The compostable bag is convenient but leaves little room for composting in the unit. Not having a urine tank could be good or bad, depending on your setup and how hands-off you want to be. Overall, this toilet seems perfect for those who want a more traditional, homey experience. It’s a bit pricier, but the features might make it worth it.

2. Best Higher Capacity: Nature’s Head Composting Toilet

The Nature’s Head Toilet is a versatile choice and one of the more well-known toilets on the market in the alternative housing space. At least half the video tours I have seen online mention this toilet.

This toilet offers separate containers for solids and liquids and a unique spider handle agitator for efficient composting.

Key Benefits

Solid Capacity: 60-80 uses – About 2-3 weeks with four people

Liquid Capacity: 2.2 gallons

Read the Full Review on the Nature’s Head Composting Toilet


  • Separates urine from solids
  • Easy to Clean & a five-year warranty
  • Big enough for everyday use


  • Won’t fit under a seat in a van
  • Men need to sit (so the urine can make it in the front)
  • You have to unbolt the entire toilet to remove the solids container, as the back of the composting unit holds all the solids
  • It is somewhat bulky in size, and Can’t place it against the wall as the lid needs space to fully open

Power: 12-Volt for Fan

Check Price –> Amazon

My Thoughts

This toilet does a good job in the capacity and composting departments. The spider handle is a neat feature that helps speed up composting. But, emptying the urine bottle could be easier, and the need for a drawer for the solids might be a drawback for some. This is one of the more expensive composting toilet brands on the market and is definitely not one of the more portable composting toilets.

3. Best Budget: Sun-Mar GTG Composting Toilet

The Sun-Mar GTG composting toilet is a compact and portable unit that is well-known in the tiny house world. It features two separate chambers for separating liquids from solids. It has an elongated seat for comfort and a small fan for odor control.

Unlike other models, it doesn’t have a crank for churning solids.

Key Benefits

Solid Capacity: 60-80 uses – About 2-3 weeks with four people

Liquid Capacity: 1.85 gallons


  • Stand or sit! Yay for the guys!
  • The urine and solid buckets are easy to access
  • Sleek and modern-looking


  • The handle on the urine container is a fabric – it could get icky
  • The urine catch bowl may be a bit shallow
  • It has less capacity than others, so may need to empty it more often

Power: 12-Volt for Fan

Check Price –> Amazon

My Thoughts

The GTG is all about convenience and versatility. Its small size makes it a go-to for tight spaces, which might mean you’ll be emptying the liquids more often. The lack of a crank for the solids is something to consider, depending on how hands-on you want to be with maintenance. I must say, it is also very sleek looking.

4. Best Compact for Van Life: OGO Composting Toilet

The OGO compact composting toilet has a modern, square design with rounded edges. It is super compact, making it a snug fit for tight spaces. A Big Win in the van life world!

One of its features is an electric solids agitator activated by a button. It weighs just 28 lbs and is easy to install in small campers or off-road vehicles. The unit also offers flexible venting options.

Key Benefits

Solid Capacity: 30 uses – 2-3 weeks with two people

Liquid Capacity: 2.4 gallons


  • Electric mixing of solids – 2 min run time
  • Smallest footprint on the market – 15″ deep x 16″ wide – the smallest composting toilet mentioned
  • The urine sensor lights up when it is almost full


  • You Will need to empty it more often
  • The seat is smaller, so it may not be comfortable for long sittings.
  • Men need to sit

Power: 12-Volt for Fan

Check Price –> Amazon

My Thoughts

The OGO has a unique design and electric agitator. It’s more comfortable than it looks, but don’t expect to sit on this thing and watch an entire Netflix show. The electric agitator is a big win for me because it makes composting a breeze.

However, the compost bucket is smaller, so you must empty it more frequently to avoid overflow. The urine plumbing options are a nice touch. It’s a top pick for a compact, easy-to-use, modern, portable composting toilet.

What Is an RV Composting Toilet?

buying a toilet

An RV composting toilet is a type of toilet that uses the natural process of composting to break down waste into usable and environmentally friendly material.

Unlike traditional flush toilets, composting toilets do not require water or plumbing.

Most composting toilets separate the solid and liquid waste.

They use a mix of organic materials such as peat moss or coconut coir in a solid waste container to treat human waste to aid in composting. 

4 Advantages of Composting Toilets in your RV or Camper Van

1. Eliminate the need for a Black Tank and increase the Gray Water Tank Capacity

When you eliminate the need for the RV’s black tank, you can use the space to store the gray tank, which is water from sinks and showers.

This increases your overall tank capacity and allows for longer periods between dumping. You also do not have to be on the lookout for a dump station.

2. Composting toilets Reduce Water Usage

One of the biggest advantages of composting toilets is their ability to conserve water.

Traditional flush toilets can use up to 2 gallons per flush while composting toilets require no water.

This not only saves on your water bill but also helps to conserve this valuable resource. Even the most resourceful toilets on the market will still need at least a gallon of water.

3. Less Maintenance and Repairs

An RV Compost toilet has few moving parts and does not require plumbing or electricity, making it much simpler to maintain than a regular toilet.

They also have a longer lifespan and are less likely to need repairs.

4. Composting toilets are Eco-Friendly

Composting toilets are a sustainable and environmentally friendly option for waste disposal.

They do not require using harmful chemicals found in regular toilets, which can pollute the environment.

Who is buying a composting toilet?

Rv with a family

Composting toilets are great for those living in alternative housing options such as tiny houses, ADUs, RVs, van conversions, off-grid cabins, pool houses, houseboats, and guest houses.

These thrones can even accommodate larger families.

These structures only sometimes have access to water to install a traditional toilet.

They may also easily access a compost pile or a portable composting system to empty the solid waste container.

How To Use a Composting Toilet for Camping or Van Living?

You will have to sit down on the toilet if it will separate the urine from the solid.

You may have to sit further back to ensure you get the solid waste in the right compartment.

Rv life

Once you are finished using the toilet, it is advised to spray the toilet seat with vinegar.

If the toilet has a manual crank to mix the solids, you must turn it a few times to fix the newest solids.

How Do RV Composting Toilets Work

Composting toilets are considered dry toilets and break down solid waste through decomposition.

Many composting toilets separate liquids and solids. The solid waste is mixed with a compost medium, such as sawdust or peat moss, to aid in composting.

This creates a more hospitable environment for aerobic bacteria to break down the waste into nutrient-rich compost. The toilet tank is a holding tank and evaporation chamber where a fan helps remove moisture from a vent hose.

What do you do with composting toilet waste?


Most of the time, you can safely dispose of the composted waste in your compost pile.

Be sure to follow proper guidelines and regulations for disposal in your area.

A normal trash can could work if you empty your solids bin into a composting or regular trash bag.

Some may bury the waste a few inches deep in the dirt if they are more remote.

The liquid waste container can be dumped in a public restroom or the shower, which goes to the gray tank.

You need to consider the capacity of the toilet, how many people will use it, and how often you are willing to dump it. Consider a higher capacity if you have a larger family or want to go longer between dumps.
