Best Camper Van Toilet: 10 Options for Different Van Builds

#1 · Best Overall

1. OGO Origin Composting Toilet

• Weight: 28 lb
• Material: Polypropylene High Density Polyethylene
• Seat Material: Polypropylene (PP)

Best for: Compact 12V composting toilet.

Why it ranks #1: Its listed 15-by-16-inch footprint targets tight van builds; a 12V agitator, urine-diverting trap door, and venting hose support a fixed composting setup.

A 15-by-16-inch footprint lets the OGO Origin fit tight van layouts, while its push-button electric agitator mixes solids without a hand crank. A urine-diverting trap door routes liquid to a front bottle, keeping solids dry as part of its composting workflow.

The 12V fan vents the system, and the listed draw of about 0.48 amps a day for the fan gives off-grid owners a concrete power consideration. A push-button agitator churns solids with composting medium, avoiding manual cranking after use. The unit is floor mounted and includes a venting hose and power cable, so installation needs space for ventilation and a 12V connection. Gloves and a mask are advised when handling waste, and local disposal rules apply.

Skip it if you want a portable, water-flush toilet without a ventilation hose; the Porta Potti Thetford 365 uses a piston pump and sealed holding tank.

The OGO Origin suits van builders with a compact floor-mount location, 12V power, and space for ventilation. Its composting workflow and waste-handling precautions are important fit considerations before installation.

#2 · Waterless Pick

2. modiwell LE-310 Dry Flush Toilet

• Dimensions: 17"D x 17"W x 11"H
• Weight: 17 lb
• Material: Engineering Plastics, Stainless Steel
• Seat Material: Polypropylene (PP)

Best for: One-touch dry-flush convenience.

Why it ranks #2: This 17-by-17-inch dry-flush unit is aimed at van life and seals waste bags at the touch of a button without using flush water.

One press starts automatic thermal waste disposal and seals the bag, giving van travelers a waterless toilet workflow without manual tank emptying. The modiwell LE-310 measures 17 by 17 by 11 inches, a low-profile shape for an off-grid setup where toilet height and water use matter.

Because flushing does not require water, the LE-310 avoids a freshwater flush tank; the automatic bag sealing instead makes waste containment central to each use. Included coagulant and bags provide the listed consumables for getting started, and the product description says the bags are tested to seal and prevent odors. The 17-inch square footprint needs floor space, while the guidance to switch off the rear power switch after use makes power management part of the routine.

Skip it if you prefer a hand-pumped water-flush toilet with tank indicators; the Porta Potti Thetford 365 provides that setup.

Pick the LE-310 if waterless use and one-button bag sealing suit your van routine. Its 17-inch square footprint, electrical operation, and need to switch off the rear power switch after use are important practical boundaries.

#3 · Adjustable Bag Length

3. modiwell R1808 Dry Flush Toilet

• Dimensions: 17 x 14 x 18 in
• Weight: 21 lb
• Material: Polypropylene, Stainless Steel, Silicone

Best for: Adjustable-angle fixed dry flush.

Why it ranks #3: Its waterless one-touch sealing and adjustable refill-bag length modes suit different waste amounts; the toilet can also rotate 90 degrees for layout flexibility.

A toilet body that rotates 90 degrees left or right lets van owners adjust its angle to suit tight cabin layouts. The modiwell R1808 combines that positioning flexibility with one-touch heat-sealed waste bags, offering waterless use in a 17-by-14-by-18-inch unit.

After use, the lid and lower sliding door must be fully closed before pressing the button; the system then wraps and heat-seals waste into a refill bag. Adjustable bag-length modes offer settings for small and large waste loads, so the bag operation can be tailored rather than limited to one stated length. Its waterproof-when-closed construction protects internal components from moisture, while the 21-pound weight and fixed installation designation make placement a more considered decision than for a lightweight portable bucket.

Skip it if you need to reposition a lightweight toilet often; the VINGLI Portable Toilet weighs 5.5 pounds and nests for storage.

The R1808 suits van or boat owners who want waterless sealing and a body angle adjustable to the available space. Account for its 21-pound weight and follow the lid-and-sliding-door closure sequence before starting.

#4 · Piston-Pump Flush

4. Porta Potti 365

• Dimensions: 16.8"D x 15"W x 16.3"H
• Weight: 8.8 lb
• Material: Plastic
• Seat Material: Plastic

Best for: Level-indicator portable toilet.

Why it ranks #4: A portable 16.8-by-15-by-16.3-inch design includes a sealed valve, tank level indicators, and a piston pump averaging 56 flushes per fill.

Built-in freshwater and wastewater level indicators let you check both tanks before setting out, while the Porta Potti 365’s piston pump averages 56 flushes per fill. Its portable format and ergonomic carrying handle suit camper van owners who need a self-contained toilet they can maneuver and monitor between trips.

The separated body gives access to the holding tanks, and the pivoting pour-out spout supports emptying and cleaning without lifting the whole unit as one piece. A sealed valve helps contain holding-tank odors, while the removable seat and cover make routine cleaning more accessible. At 16.8 by 15 by 16.3 inches and 8.8 pounds, it is a manageable option for a van, though the listed dimensions still call for a dedicated storage spot.

Skip it if you need a toilet that seals waste into disposable bags; the modiwell LE-310 uses one-click dry-flush sealing instead.

Choose the Porta Potti 365 if you want a portable, water-flush toilet for van trips and value tank-level checks and a pivoting pour spout. Allow room for its 16.8-inch depth and plan to empty its holding tank.

#5 · Smallest Flush Unit

5. Porta Potti 135

• Dimensions: 13.54"D x 15.12"W x 12.13"H
• Weight: 8 lb
• Material: Plastic
• Seat Material: Plastic

Best for: Compact dual-tank flush toilet.

Why it ranks #5: At 13.54 by 15.12 by 12.13 inches, it is a compact portable flush option with 2.6-gallon fresh- and wastewater tanks.

At 12.13 inches tall, the Porta Potti 135 offers a compact, portable water-flush option for camper vans where a taller unit is difficult to place. Its separate 2.6-gallon fresh-water and waste-water tanks provide a self-contained flush setup without relying on a vehicle plumbing connection.

The bellows pump adds water to the bowl, while the sealed valve keeps odors in the holding tank, linking a straightforward flush action with contained waste storage. Its rotating pour-out spout supports emptying, and the removable seat and cover help with cleaning after use. The listed dimensions—13.54 by 15.12 by 12.13 inches—and 8-pound weight help buyers assess carrying and storage, though both tanks share a 2.6-gallon capacity.

Skip it if you want a larger listed waste tank for fewer emptying stops; the Camco portable toilet holds 5.3 gallons.

Choose the Porta Potti 135 for a compact van setup that needs a portable flush and self-contained tanks. Its 2.6-gallon waste capacity is the key boundary if you expect long stretches between emptying.

#6

6. Camco Portable RV Toilet

• Dimensions: 16.25"D x 14"W x 17"H
• Weight: 13 g
• Material: Blend, Polyethylene (PE)
• Seat Material: Plastic

Best for: Larger-tank portable flush toilet.

Why it ranks #6: Its detachable 5.3-gallon waste tank and 2.5-gallon fresh-water tank offer substantial capacity in a portable flush design for camping and road trips.

A 5.3-gallon detachable waste tank gives the Camco portable toilet more holding capacity than compact units with smaller tanks, making it a practical candidate for longer camper van outings. Its 2.5-gallon top-mounted freshwater tank supplies the flush, so the unit operates as a self-contained toilet.

The upper section holds the bowl, seat, lid, and 2.5 gallons of fresh water; a removable cap provides access for filling the flush tank. Below, a sliding gate valve opens for waste and closes to create an odor- and water-tight seal. Detaching the 5.3-gallon holding tank supports separate emptying, but that capacity also means planning how to handle the tank when full. Its 16.25-by-14-by-17-inch dimensions define its storage footprint.

Skip it if you need a lightweight toilet that nests into itself for storage; the VINGLI Portable Toilet weighs 5.5 pounds and separates into two parts.

The Camco suits van campers who want a portable flush toilet with a detachable, 5.3-gallon waste tank. Check that its 16.25-inch depth fits your storage area and that you can manage the tank at emptying time.

#7

7. Kohree 6.34-Gallon Portable Toilet

• Dimensions: 16.3"D x 13.7"W x 17.5"H
• Material: High-Density HDPE and PP
• Seat Material: Polypropylene (PP)

Best for: High-capacity portable cassette.

Why it ranks #7: The portable cassette design lists a 6.34-gallon waste tank and 5.3-gallon fresh-water tank, reducing emptying frequency for users who have room to store it.

The Kohree KR3128 pairs a 6.34-gallon waste tank with a 5.3-gallon freshwater tank, giving camper van users substantial listed capacities in a portable toilet. Its elongated, comfort-focused seat targets adult use, while its 16.3-by-13.7-inch footprint suits layouts that can spare the floor space.

The larger waste reservoir is intended to reduce how often it needs emptying, and the freshwater capacity is listed to provide approximately 130–140 flushes. Those capacities support longer use between service tasks, but the combined tanks mean owners must plan for filling and waste disposal. At 17.5 inches high, the unit stays portable rather than relying on fixed plumbing; its HDPE and polypropylene construction specifies the tank and body materials.

Skip it if you need wheels to move a portable toilet when empty; the Kohree KR31210 listing specifically includes a wheeled design.

The KR3128 suits van users who want a portable flush toilet with larger stated tank capacities and an adult-focused seat. Make sure its 16.3-by-13.7-inch footprint fits and plan for full-tank handling.

#8

8. Kohree Portable Toilet with Wheels

• Dimensions: 18.3"D x 14.1"W x 17.71"H
• Material: High-Density HDPE and PP
• Seat Material: Polypropylene (PP)

Best for: Wheeled large-capacity toilet.

Why it ranks #8: This 6.34-gallon portable toilet adds wheels for moving the unit when empty and a lengthened seat, though the listing cautions about tipping when filled.

Wheels help move the Kohree portable toilet when it is empty, a useful handling feature for camper van owners who need to roll a toilet between storage and use. Its 6.34-gallon capacity and lengthened seat target adults seeking a roomier portable option.

The listed 18.3-by-14.1-by-17.71-inch dimensions give buyers a concrete sense of the floor space this portable unit needs, while its longer seat is intended to improve adult comfort. Wheels assist movement when empty, but the product advises attention to the usage angle when it contains water to prevent tipping. That caution matters in a mobile setup: plan its parking and movement around whether the tank is empty or filled.

Skip it if you want a smaller portable toilet with stated tank capacities and flush count; the Kohree KR3128 lists both.

The wheeled Kohree suits van users who value a longer seat and easier movement while the unit is empty. Its 18.3-inch depth and the filled-unit tipping caution should guide where and how you use it.

#9

9. VINGLI Detachable-Bucket Commode

• Dimensions: 18"D x 15.5"W x 30.9"H
• Weight: 5.5 lb
• Material: Polypropylene (PP)
• Seat Material: Polypropylene (PP)

Best for: Lightweight nested commode.

Why it ranks #9: Its 5.5-pound weight, detachable inner bucket, and nested storage suit occasional or emergency use, but the listing gives a tall overall height of 30.9 inches.

At 5.5 pounds, the VINGLI Portable Toilet separates into two parts and nests together, making it easy to carry and store between camper van uses. Its removable inner bucket supports direct emptying, while the dual-lid seal helps reduce odors during use.

The polypropylene body keeps the listed weight low, and nesting the detached sections helps reduce the space needed for storage when the toilet is not in use. The removable inner bucket provides access for emptying; the product also says a toilet bag can be used in the barrel so cleaning is not needed in that use pattern. A paper holder is included, and the 18-inch depth and 15.5-inch width still need to be accounted for in a van layout.

Skip it if you want a water-flush toilet with a detachable holding tank; the Camco Portable RV Toilet has a 5.3-gallon tank.

Choose the VINGLI if portability, nesting storage, and a removable bucket matter more than a flush system. Its 18-inch depth and bucket-based waste handling are important considerations for a compact van bathroom.

#10

10. SEAFLO Gravity-Flush RV Toilet

• Dimensions: 11.71"D x 15.27"W x 18.4"H
• Weight: 12 lb
• Material: Polypropylene (PP)
• Seat Material: Polypropylene (PP)

Best for: Residential-height RV replacement.

Why it ranks #10: This is a fixed RV plumbing toilet rather than a self-contained van unit; it requires a floor flange, and its listed dimensions and installation differ from portable options.

An 18.4-inch residential-height seat makes the SEAFLO RV Toilet a fit for camper owners who want a taller fixed toilet rather than a portable cassette. The foot-pedal gravity flush and standard RV plumbing connection support familiar, hands-free flushing in a connected bathroom.

Pressing the foot pedal operates the gravity flush, leaving the user’s hands free, while the oversized anti-stick bowl and soft-close seat add specific usability touches. The lightweight plastic body weighs 12 pounds, and the included gasket seal, mounting screws, and screw covers support a two-bolt installation. It fits standard RV plumbing, but the floor flange is sold separately, so installation planning must account for that component and the listed 9.5-inch rough-in.

Skip it if you need a standalone portable toilet without RV plumbing installation; the Camco Portable RV Toilet has a detachable waste tank.

Choose the SEAFLO for a camper bathroom with compatible RV plumbing and a preference for residential seat height and pedal flushing. Check the 9.5-inch rough-in and source the separately sold floor flange for installation.
