Types of RV Toilets and Their Features

Any toilet unit you may choose for your RV will either be plumbed-in or standalone. Plumbed-in units will be mounted to your water supply tank and the black water tank, whereas standalone toilets have their own waste container and are generally more versatile since they can be used not only in RVs.

So, plumbed-in RV toilets can be one of the following:

  • Pedal flush toilets. The most common option with the pedal flushing mechanism. If you press the pedal half-way, it will fill the bowl to create some kind of siphon — that’s why it’s recommended to do BEFORE you do your job — and if you press it all the way through, it will flush the waste in your black water tank.
  • Macerating toilets. These use motor-powered blades to break up waste into smaller particles before discarding it into your black water tank. Also known as waterless toilets, they can be a good pick for long-time camping trips where the water might become scarce.
  • Vacuum toilets. Similar to macerating toilets, these units use a vacuum pump to break the waste and then force it down your black water tank.

As for the standalone RV toilets, you can count on two types:

  • Portable toilets. These toilets have a waste container that you can dump into a residential toilet or public restroom when full. The obvious advantage is portability: these toilets can be used for boating, outdoor camping, and other activities. But you might have to deal with the smells if you plan to use it for long-haul RV trips.
  • Self-containing toilets. Also known as composting toilets, these units use aerobic bacteria to break down waste. These toilets are odor-less and very efficient: they can break not only waste but also toilet paper — the main reason for RV clogs — and food waste. Composting toilets are approved by the US Environmental Protection Agency and, when chosen properly, can break the waste down to 10-30% of its original volume (1).

Thetford 31672 Aqua Magic

We open this review of the best RV toilets with the 31672 model by the Thetford Aqua Magic series. It’s a durable plastic toilet with a high-profile structure and pedal flush that preserves the comfort of home on the go.

So, the pedal flush is straightforward to use: when you press it halfway, it adds water to the bowl. When you press it fully, it flushes everything and covers the entire surface of the bowl, so there’s no waste remained.

Another awesome feature of the 31672 model is that it’s high-profile. The seat height is 17-½ inches, which can suit most users. So, if you travel with your children or parents, this might be useful, although you can also purchase a low-profile option.

Finally, Thetford Aqua Magic is incredibly easy to clean. It’s made of durable plastic with a glossy surface, so no waste will adhere to it. Plus, the lid of the toilet is textured and repels water, which adds to a more comfortable experience.

The Bravura features the same pedal flush system as the whole Aqua-Magic series, but it operates a little differently. Aside from filling the bowl by halfway pressing, and flushing the bowl with a full pressing, this toiled also has a pulse flush mode that instantly covers the whole bowl and rinses all the junk.

Also, the 31122 model is easy to maintain. The seat and cover pod can be quickly removed for cleaning, and the front shroud features a pull-off mechanism to reach the pedal system and mounting bolts, in case you need to replace or repair them.

Also, the 300 series model is built with tall or overweight users in mind. First, it’s higher than the standard RV toilets and doesn’t require a pedestal. Second, it offers a wider, residential-style seat that adds some comfort for the people of large build.

Things to Look for When Choosing the Best RV Toilet


Generally, RV toilets are made of durable polypropylene plastic — the kind that is used for making toilet seats for residential toilets. Polypropylene is hard yet flexible enough to survive the bumps and pits on the bad road without cracking. It’s also relatively easy to clean since polypropylene has a smooth finish and doesn’t stain. However, in a long run, polypropylene plastic might start to soak in odors, and you might start to smell the funky things in your RV.

Also, you can count on ceramic toilets that resemble the feel of a residential unit. Ceramic bowls with a glossy finish are even more resistant to stains and smells than plastic bowls, but they’re pretty fragile, and may not survive an overly bumpy road. Plus, they are 2-3 times more expensive than polypropylene toilets, which can also be a turn-off for some users.

RV Space and Toilet Dimensions

RVs have limited space, especially when it comes to the bathroom, so be sure to make your measurements before going shopping.

It’s advisable to measure the depth, width, and height of your old RV toilet and add 4 inches of space to the sides and 6-inch clearance to the front, so you’ll know the approximate space you need to not feel cramped.

The profile of the toilet also plays a huge role. Although it’s more a matter of preference, we recommend going for standard and taller models simply because they suit most people. Low-profile toilets may occupy less space, but if you’re a tall or overweight camper, they might be uncomfortable to use unless you have a pedestal.

Holding Tank Capacity

If you decided to go with a portable RV toilet, pay attention to a holding tank capacity. Smaller holding tanks require to empty them more frequently, which means more stops on the way. Larger tanks are more recommended for long-hour trips, but they can be difficult to empty single-handedly.

Ease of Maintenance

RV holding tanks used for sewage (the gray and black water tanks) are prone to generating bad odors, which means that you can start to notice funky smells in your vehicle sooner or later, especially if the trip is long. However, if you plan to use deodorants and chemical toilet products to eliminate odor, be sure to choose more eco-friendly alternatives such as enzyme-based or oxygen-based cleansers, as the Department of Toxic Substances Control recommends (2).


The tallest one we’ve reviewed is the Aqua-Magic 31672 by Thetford, which is 17.5 inches high. According to user reviews, Thetford toilets tend to be higher than in other brands, so if you need a toilet for a tall camper, you can choose this brand.

The most common reasons for the toilet odor in your RV include the clog or damage in the black water tank, a leaky toilet, or improper cleaning. You can clean and sanitize the black water tank and fix the leaky toilet by yourself. But if the problem is damage or clogs in the black water tank, it’s better to contact a repair specialist.

Grey water that comes from the kitchen and shower, is perfectly suitable for flushing your RV toilet, and can save you significant amounts of clear water, especially if you go dry camping. However, to be able to use it, you need to install a water recycling kit in your RV, which will reroute the gray water into your flushing system.

Bleach is allowed to use as a cleaning agent for RV toilets, however, during the trip, it’s recommended to use ‘safe’ cleaners, such as enzyme-based or mineral, and leave the bleach solution for sanitation purposes after emptying your black water tank. That’s because the black water tank is an ecosystem of some sort and the bacteria that growths inside can actually break down some waste. When you pour the bleach into the tank that has waste in it, it kills all the bacteria, which may result in clogs. That’s why it’s better to empty your black water tank first, and then use the bleach solution (¼ cups of bleach per 1 gallon of water) and rinse off all the residue.

One of the efficient options for unclogging on-the-road is using a flexible tank wand that can be connected to your water supply line and reach the depths of the tank pipe. The spray attachment on the nozzle will release a high-pressure stream of water that will soak up the clog and break it down into smaller particles.
