Best Cassette Toilet For Van: 7 Models Compared

#1 · Best Overall

1. Thetford C224-CW

• Weight: 8 kg

Best for: Swiveling manual-pump layouts.

Why it ranks #1: Its swivelling form, hand pump, 18 L waste tank, and 9 L fresh-water tank give van builders clear installation and capacity details.

A swiveling bowl gives the Thetford C224-CW a positioning option that can help when planning a tight van bathroom. It pairs a hand pump with an 18-liter waste-water tank and a 9-liter fresh-water tank, all in a unit listed at 8 kilograms and about 72.7 by 39.4 by 58 centimeters.

The swiveling design gives the bowl a way to change orientation within the installation, a useful consideration when mapping the available bathroom space. Its hand pump provides manual operation, while separate 9-liter fresh-water and 18-liter waste-water tanks define the capacities to plan around for trips and servicing. The listed 8-kilogram weight and 72.7-by-39.4-by-58-centimeter dimensions offer concrete checks for handling and placement before choosing it for a van.

Skip it if you prefer an electric bowl-water button; the Thetford 32812 adds one, though its bench-style installation and 22-pound weight call for more space and handling.

The C224-CW is a fit for van owners who need a swiveling toilet and are comfortable with hand-pump operation. Check its stated dimensions and tank capacities against your installation area and servicing routine.

#2 · Easiest Tank Handling

2. Thetford 32812

• Weight: 22 lb
• Dimensions: 29 x 17.25 x 21.75 in

Best for: Bench-style van installation.

Why it ranks #2: The bench-style toilet has an electric water button, a left- or right-installable LED level indicator, and a wheeled tank with retractable handle.

A bench-style layout gives the Thetford 32812 a different footprint and setup from a freestanding portable toilet, with a level indicator and left-or-right installation option. Its electric push button adds water to the bowl, while the waste holding tank’s wheels and retractable handle provide a way to move that tank.

The left-or-right installation option gives buyers flexibility when planning the toilet’s position, and the LED level indicator provides a visible way to monitor tank level. Bowl water is added with an electric push button, so the flush workflow differs from a hand-pumped portable model. The waste holding tank has wheels and a retractable handle, which can make moving it for emptying more manageable. At 29 by 17.25 by 21.75 inches and 22 pounds, it calls for a deliberate space and weight check.

Skip it if you need a lightweight portable unit rather than a bench-style toilet; Kohree’s 11.6-pound KR3126 is listed at roughly half this model’s weight.

Choose this Thetford for a van layout that can accommodate its bench-style form and where the left-or-right option helps placement. Its 29-inch length and electric water button are important installation and operating considerations.

#3 · Floor-Mounted Option

3. Thetford C223 CS

• Weight: 17.7 lb
• Material Type: Plastic

Best for: Floor-mounted Thetford installations.

Why it ranks #3: Its listed floor-mounted installation type suits buyers seeking a fixed van toilet, though the supplied listing gives few operating or tank details.

A floor-mounted installation type makes the Thetford C223 CS a candidate for van layouts planned around a fixed toilet position. The listing identifies a plastic unit weighing 17.7 pounds, with package dimensions of 29 by 21.75 by 17.25 inches; those details help assess placement and handling before installation.

The floor-mounted classification points to an installation approach different from a portable toilet that can simply be moved around the van, so the available floor area and intended position matter. Its 17.7-pound listed weight is a practical handling consideration during setup, while the 29-by-21.75-by-17.25-inch package dimensions give a reference for space planning. The listing specifies plastic construction but supplies no tank capacities or flushing details, so buyers should use the listed installation type and dimensions as their available planning facts.

Skip it if you need wheels to move a toilet when empty; Kohree’s KR3129 lists them, although its guidance cautions about tipping when water is inside.

This Thetford suits van owners planning a floor-mounted toilet position and able to accommodate the listed package dimensions. Consider that its listing identifies a mounted installation, not a wheeled portable unit.

#4 · Largest Waste Tank

4. YITAHOME Portable RV Toilet

• Weight: 14 lb
• Material Type: HDPE+PP
• Dimensions: 16.3"D x 14.4"W x 16.5"H

Best for: Higher-load portable toilet users.

Why it ranks #4: The portable design lists a 20 L waste tank, 12 L fresh-water tank, and 441 lb maximum load, useful when a fixed installation is unsuitable.

A stated maximum load of 441 pounds is the YITAHOME’s clearest differentiator for buyers choosing a portable van toilet for adult use. Its 12-liter freshwater tank and 20-liter wastewater tank set out the two capacities, while the HDPE-and-PP body measures 16.3 by 14.4 by 16.5 inches.

The 441-pound maximum load gives buyers a stated capacity to consider, while the HDPE-and-PP construction is described as a precise-molded, strong structure. Separate 12-liter freshwater and 20-liter wastewater tanks clarify the water supply and waste storage available for trip planning. The product guidance says to fill the fresh-water tank before use and keep the instant valve open during use to avoid air bubbles, so setup and operation require following those steps. Its 16.3-by-14.4-inch footprint helps with placement checks.

Skip it if you want wheels for moving the toilet when empty; Kohree’s KR3129 lists wheels, with guidance to watch its angle when water is inside.

The YITAHOME fits buyers who prioritize its stated load limit and want separate freshwater and wastewater capacities. Allow for its listed footprint, and follow the stated fill and valve steps before and during use.

#5 · Best for Mobility

5. Kohree Wheeled Portable Toilet

• Material Type: High-Density HDPE and PP
• Dimensions: 17.7"D x 14.1"W x 17.7"H

Best for: Wheeled toilet for empty transfers.

Why it ranks #5: Wheels help move this portable model when empty; its stated tanks hold 20 L of fresh water and 18 L of waste.

Integrated wheels let the Kohree KR3129 roll more easily when empty, making repositioning or transport less dependent on lifting. It also lists a 5.3-gallon fresh-water capacity and a 4.8-gallon sewage tank, pairing movable handling with sizable stated tank volumes in a portable 17.7-inch-high unit.

The wheels support moving the toilet when empty, and Kohree specifically advises attention to the angle to prevent tipping if it contains water; that makes the distinction between empty transport and filled use important in a van. The 5.3-gallon fresh-water capacity and 4.8-gallon sewage capacity can reduce emptying frequency according to the product information. Its 17.7-by-14.1-by-17.7-inch dimensions and HDPE-and-PP construction help buyers evaluate storage and handling needs.

Skip it if you need a familiar elongated seat and do not need wheels; Kohree’s KR3126 lists a 13-inch seat length and a handle-pump flush.

This KR3129 fits van owners who want wheels for empty transfers and value the listed tank capacities. Plan where it will be stored, and follow the stated caution about angle and tipping when it contains water.

#6

6. Kohree Diagonal Portable Toilet

• Weight: 11.6 lb
• Material Type: High Density Polyethylene (HDPE)
• Dimensions: 14.5"D x 16.5"W x 17"H

Best for: Home-seat comfort in compact vans.

Why it ranks #6: Its 13-inch elongated seat and 11.6 lb weight may suit a removable setup, but the supplied details do not establish tank capacities.

An elongated 13-inch seat gives the Kohree a familiar, home-toilet-like seating length, which can make daily use feel less cramped in a camper or travel trailer. Its portable HDPE body measures 14.5 by 16.5 by 17 inches, while a T-type flush nozzle and high-pressure handle pump provide the flushing setup.

The diagonal seat shape and extended 13-inch length prioritize a familiar sitting position, while the listed 14.5-by-16.5-inch footprint helps shoppers assess whether it can occupy their van’s available floor area. A 2.64-gallon water tank and T-type flush nozzle work with the high-pressure handle pump for manual flushing, so operation does not rely on an electric flush button. Its HDPE construction and 11.6-pound weight are useful considerations when planning to move or store the portable unit.

Skip it if you want a wheeled unit for moving it when empty; the Kohree KR3129 adds wheels, though its guidance cautions against moving it filled with water.

This Kohree suits van travelers who value a longer, familiar-feeling seat and manual flushing. Check the 14.5-by-16.5-inch footprint against your available floor space, and account for operating the handle pump for each flush.

#7

7. Dometic Cassette Toilette

• Weight: 2.58 kg
• Material Type: Plastic

Best for: Dometic cassette replacement buyers.

Why it ranks #7: The listing describes a replacement cassette for a CT4110 rather than clearly establishing a complete van toilet, making compatibility especially important.

A stated 30-liter capacity distinguishes this Dometic cassette, while its listing identifies it as a replacement for the CT4110 product. The plastic cassette has a listed lightweight, impact-resistant, high-gloss surface, making compatibility with the intended Dometic setup the first practical consideration for van owners.

The CT4110 replacement reference makes this listing relevant to buyers maintaining a specified Dometic cassette toilet rather than choosing a generic portable unit. Its 30-liter capacity gives a concrete volume to consider for the system’s waste-handling needs. The plastic material is described as lightweight and impact-resistant, and the high-gloss surface is another stated construction detail. Listed dimensions are 270 by 275 by 465 millimeters, so measuring the existing cassette helps assess whether this replacement is the intended match.

Skip it if you need a complete portable toilet rather than a cassette replacement; the Kohree KR3126 is listed as a portable toilet with an elongated seat and handle-pump flush.

This Dometic suits owners replacing a cassette in the specified CT4110 context who want the listed 30-liter capacity. Treat it as a replacement component, and check its stated dimensions against the cassette being replaced.
