There are six main RV toilets and van toilet options to choose from: cassette, hybrid cassette, RV toilet with built-in plumbing, composting, portable, and dry. They differ on six things that actually matter day to day, and this guide compares all six options toon all six variables, so you can decide which one belongs in your build.
At Noovo, we exclusively use the hybrid cassette toilet in our builds due to its convenience, effective odor control, and ease of emptying without requiring a black water tank. However, we often suggest other options for van builders with different requirements, budgets, or eco-consciousness levels, especially for those planning extensive off-grid adventures or prioritizing minimal water usage. Keep reading for a full overview of each style, including ease of installation, water usage, space needed, waste disposal, odor control, cost, and more.
Cassette toilets balance convenience and simplicity with low water usage, high odor control, and easy emptying, without a black water tank.
Composting toilets require no water and provide excellent odor control, ideal for long periods without facilities and minimal environmental impact.
RV toilets offer the most home-like experience with excellent odor control, and are popular for those with regular access to campground hookups and dump stations, and with the stomach and budget for black tank maintenance.
People search for RV toilets and van toilets as if they were the same product category. In practice, the vehicle decides the shortlist.
A Class A or Class C motorhome has room for a residential-style bowl sitting directly above a black water tank of 25 to 50 gallons. That is the classic RV toilet: it flushes like home, it holds a week or more of waste, and it needs a dump station. Nobody in a big rig thinks twice about it.
A Class B camper van has neither the floor area nor the payload for that setup without giving up something you will miss more, usually storage or fresh water capacity. So the van world leans toward self-contained systems: cassette, hybrid cassette, composting, and dry. They hold less, they get emptied more often, and in exchange they free up the space and the plumbing complexity that a black tank demands.
The practical rule: if you can park at a campground with full hookups most nights, an RV toilet with built-in plumbing is a genuinely comfortable choice. If you move often, boondock, or want the simplest possible system, the cassette family is what the van market has settled on. Everything below is organized around that trade-off.
One table, every option, the six criteria that decide the outcome. Prices are typical 2026 street prices for the unit itself and exclude installation and plumbing.
| Toilet type | Installation | Water use | Odor control | How you empty it | Space needed | Typical cost | Best for |
|---|---|---|---|---|---|---|---|
| Cassette | Low, DIY friendly | Low | Moderate, chemical additives | Pull the cassette, empty at a dump point or public restroom | Moderate | $150 to $900 depending on flush type | First builds, short trips, tight floor plans |
| Hybrid cassette | Moderate, basic plumbing | Low | High, advanced sealing | Pull-out cassette, no black tank | Moderate | $600 to $1,000 | Full-time van life that still wants a home-like bowl |
| RV toilet (built-in plumbing) | High, professional plumbing | High | High when maintained | Black water tank at an RV dump station | High, toilet plus tank | $200 to $600 for the bowl, plus tank and install | Campgrounds with full hookups, buyers coming from a larger RV |
| Composting | Moderate, needs a vent | None | High when maintained | Separate liquid bottle often, solids bin every few weeks | Moderate | $1,000 to $1,200 | Long off-grid stretches, minimal environmental impact |
| Portable | Very low, no install | Moderate | Low to moderate | Carry the base tank to a dump point or restroom | Minimal, stows away | $100 to $250 | Weekend trips, backup system, rentals |
| Dry | Low, secure mounting | None | Moderate to high with cover material | Bag or bin removed by hand | Moderate, often very compact | $50 to $350 | Stealth camping, remote travel, minimalist builds |
Cassette toilets are the most popular choice for camper van builds due to their simplicity and compact design. They feature a removable waste tank (the "cassette") that can be easily detached for emptying. With low installation complexity and minimal water usage, cassette toilets are an excellent option for those new to van life or working with limited space.
Key features
Waste cCapacity is the number to look at before anything else. The widely used Thetford C223-CS cassette holds 4.7 gallons of waste, which works out to roughly three to five days for two people before a trip to a dump point. Manual-flush cassettes start around $150; electric-flush models with a rotating bowl and a tank level indicator sit at the top of the range.
Cassette toilets are particularly suitable for shorter trips, and for smaller vehicles where space is at a premium. The ability to empty the waste tank at public restrooms or campground facilities adds convenience for travelers who prefer not to deal with full-size RV dump stations. However, the moderate odor control and need for frequent emptying, especially on longer trips, are the key trade-offs to weigh.
Hybrid cassette toilets combine the best features of traditional cassette toilets and RV toilets, offering improved functionality and convenience. These units typically feature a more permanent installation with a pull-out cassette for easy waste disposal.
At Noovo, we've chosen this option for our van builds due to its balance of ease of use and effective waste management. The hybrid cassette gives our customers a similar experience to a plumbed RV toilet but without the drawbacks around maintenance, black water management, and all the costs accompanying RV toilets. Both the Noovo Lite and the Noovo Plus ship with a full-time toilet and shower built around it.
Key features
In summary, hybrid cassette toilets are an excellent choice for camper van living when you want a more permanent solution without the need for a black water tank. They offer improved odor control and a more home-like experience compared to standard cassette toilets, while still maintaining the ease of emptying.
RV toilets with built-in plumbing offer the most home-like experience in a van conversion. These systems are permanently installed and connected to a black water tank, mimicking the functionality of a residential toilet. While they require more complex installation and maintenance, they provide a high level of comfort for full-time van dwellers. They are particularly popular with retirees since they require no adjustment for someone coming from a full-size RV experience.
Key features
Gravity-flush models are the standard here. A Dometic 310 gravity flush toilet is the archetype: a full-size ceramic bowl, a residential seat height, and a foot pedal with an adjustable water level. Two variants matter when you measure your bathroom. Standard height feels like home and suits taller people; low profile buys back a few inches of headroom in a van where every inch is contested.
RV toilets are ideal for those who frequently stay at campgrounds with full hookups or have regular access to dump stations. They offer excellent odor control and the most familiar user experience. However, they require more water, space, and maintenance than other options, including regular black tank cleaning and monitoring.
Composting toilets are an eco-friendly option that separates liquid and solid waste, using natural processes to break down solids into compost. These toilets are popular among environmentally conscious van lifers and those who spend extended periods off-grid.
Key features
Two units dominate the van market and they trade off against each other in a useful way. The Nature's Head is the larger of the two, and its solids bin typically runs 60 to 80 uses for a couple before it needs emptying. The OGO Origin has a noticeably smaller footprint and an electric agitator instead of a hand crank, but the smaller bin means emptying every 25 to 35 uses. Both sit in the $1,000 to $1,200 range, which is the highest entry price of any option here.
The liquids bottle, not the solids bin, is what dictates your rhythm. It fills in one to two days for two people and it has to be emptied before it does, which is the part most first-time owners underestimate.
Composting toilets are excellent for long-term off-grid living and minimizing environmental impact. They require no water and produce usable compost, but need more frequent maintenance and user involvement in the waste management process. Some users may need time to adjust to the different use and maintenance routines.
Portable toilets are simple, self-contained units that don't require permanent installation. They're a popular choice for weekend warriors or those who want a flexible toilet solution in their van.
Key features
The classic is the Porta Potti style two-part unit: a fresh water reservoir on top, a waste tank below, typically 2.6 to 5.5 gallons. Sizing matters more than brand here. The smallest models are light enough to carry one-handed when full, the largest are not, and that single detail decides whether you actually use it or resent it.
Portable toilets are ideal for occasional use or as a backup solution. They're easy to move and require no setup, making them versatile for various van layouts. However, they typically have smaller waste capacities and may require more frequent emptying, especially on longer trips or with multiple users.
Dry toilets, also known as waterless toilets, are simple systems that collect waste without the use of water. They often use biodegradable bags or a bucket system, making them a low-tech but effective solution for basic waste management in a van.
Key features
The range runs from a bucket with a seat and a bag of sawdust at around $50, to purpose-built separating units with a sealed liner system in the $250 to $350 range. The expensive ones are not better at the job, they are better at not looking and smelling like a bucket, which in a space the size of a van is worth real money.
Dry toilets are well-suited for remote and off-grid locations where water conservation is crucial. They offer effective odor control when properly maintained and are relatively simple to use. However, they require more hands-on waste management and may not provide the same level of comfort as water-based systems for some users.
This is the question that decides whether you enjoy your system or dread it, and it gets skipped in most comparisons.
Cassette and hybrid cassette:. Any RV dump station, but also any public restroom, campground toilet, or marina facility, because the cassette is a sealed portable tank you carry. That flexibility is the whole argument for the format. Practically, plan on emptying every three to five days for two people.
Black water tanks:. RV dump stations only, and you need the hose, the gloves, and roughly fifteen minutes. Sanidumps and campground directories map them; most state parks, many truck stops, and a large share of private campgrounds have one. If your travel style takes you far from those, a black tank stops being a comfort and starts being a constraint. Our guide to camper van overnight parking covers where to commonly find dump stationsthose facilities cluster.
Composting and dry:. Solids go into a trash receptacle in a sealed bag, which is legal and standard practice in most of the United States. Liquids can be diluted and dispersed away from water sources, or emptied into a toilet. Where you are far from facilities, the Leave No Trace waste guidance is the reference: solid waste buried in a cathole 6 to 8 inches deep, at least 200 feet from water, camp, and trails, and toilet paper packed out or buried with it. Some alpine and desert areas require packing everything out, so check the land manager's rules before you rely on burying anything.
Portable. Same as cassette, with the caveat that a full, 5-gallon base tank weighs close to 45 pounds.
Every water-based system in this comparison can freeze, and the consequences differ sharply.
A black water tank that freezes with waste in it can crack, and replacing it means pulling apart the floor of the van. A cassette that freezes is a nuisance, not a repair bill: you carry it inside and it thaws. Composting and dry toilets do not care about temperature at all, which is one of the quiet reasons they show up so often in ski-season builds.
If you plan on winter travel, the toilet decision and the insulation decision are the same decision. Our guide to winterizing a camper van walks through winterizingthe rest of the water system for those storing their van in colder months.
There are a lot of toilet options, many of which are easy to use, clean, and store. Another thing to decidesettle is where to put the toilet in the vanin the van the toilet goes. Depending on which one you choose, some can be stowed away in a cabinet or bin, or for more full-time use they can be built in combination with your shower set-up. Check out the Noovo bathroom options for ideas.
If you still aren't sure which one is right for you, think about what length of trips you will be taking in your van.
Consider either a hybrid cassette toilet or an RV toilet with built-in plumbing. These options offer the best balance of comfort, odor control, and waste capacity for extended travel. The hybrid cassette provides easier emptying, while the RV toilet offers a more home-like experience if you have regular access to dump stations.
Portable or standard cassette toilets are excellent choices. They're easy to install, use, and maintain for weekend getaways or brief road trips. These options don't require permanent installation, saving space when not in use.
Prioritize compact, self-contained options like dry toilets or composting toilets. These use minimal space, require no water hookups, and can be easily concealed. They're ideal for boondocking or urban stealth camping where discretion and self-sufficiency are key. If that is your plan, our list of off-grid camper van essentials covers the rest of the system.
Capacity per person can be the determining factor in toilet choiceis what breaks first. A 4.7-gallon cassette that lasts a solo traveler a week lasts a couple three days. Either accept the rhythm, carry a spare cassette, which is the trick most full-timers land on eventually, or move up to a plumbed system with a real tank.
Every Noovo build gets a hybrid cassette toilet paired with a full-time shower, in the Noovo Lite, the Noovo Plus, and the Noovo Next.
The reasoning is the same one we would tellgive a customer standing in the factory. A black water tank in a Class B van costs you storage volume and payload you will want back within a month, and it ties your route to dump stations. A composting toilet is a genuinely good system, but it asks the owner to manage a process, and most people buying a finished van are buying their way out of managing processes. The hybrid cassette sits between them: it looks and flushes like a home toilet, it seals well enough that the bathroom does not announce itself, and emptying it is a five-minute job you can do almost anywhere.
Because our vans are built in-house and RVIA certified, the toilet, the water system, and the ventilation are engineered as one system rather than assembled from parts that happen to fit. That is also why we do not offer a black tank option: it would compromise the rest of the layout more than it would add.
