The Thetford Porta Potti 365 is a portable camping toilet with a piston pump, plastic body and plastic seat. Its dimensions are 16.81 x 15.08 x 16.3 in, and it weighs 8.8 lb.
It suits a camper who can make room for its height and prefers a manual piston flush. The available capacity and indicator details are limited, so buyers who need to plan emptying intervals or see the waste level should compare models with those features stated.
Is the Thetford Porta Potti 365 a good fit?
The 365 is a sensible choice when its footprint, height and pump style fit your space and routine. It is less suitable if you need confirmed tank capacities or a stated waste-level indicator before you buy.
Thetford Porta Potti 365: Best for piston-pump simplicity
- Piston pump flushing system
- 16.81 x 15.08 x 16.3 in
- 8.8 lb
- Plastic construction
A portable toilet with a piston pump and plastic construction. Check its dimensions against your available space.
Pros
- Piston pump
- 16.3 in height
- 8.8 lb weight
Cons
- Tank capacities not stated
- Waste-level indicator information not stated
The dimensions give you a concrete starting point for checking storage and use areas. Measure the floor space, storage opening and route through doors, then leave enough room to position the toilet and move around it.
Don't treat a product that fits in storage as automatically easy to use. The spot where it will sit, the path to carry it and the place where it can be emptied all matter.
The 365 weighs 8.8 lb, which is less than the Camco at 11.5 lb and the Kohree at 14 lb. If you regularly move the toilet by hand, weight is one useful point of comparison, along with the shape and size of the carrying route.
Who should buy the Porta Potti 365, and who should skip it?
Buy the 365 if you want a piston-pump toilet, its 16.3 in height works for your space, and its unspecified tank capacities are acceptable for your plans. Skip it if a low seat height, stated capacity or waste-level indicator is a deciding requirement.
A compact camper or boat setup may benefit from a portable toilet that has a defined footprint and can be moved between use and storage. Still, compare the actual measurements with your available space instead of relying on labels such as “compact.”
For a shorter Thetford option, the 345 stands 12.99 in high and has stated flush-water and waste-holding capacities. If you want to track waste level, the 345 and Kohree have stated waste-tank indicators.
If detachable tank design matters more than staying with Thetford, compare the Camco and Kohree. Both have detachable holding tanks, though their pump systems, dimensions and weights differ.
How do you choose between these portable toilets?
Choose by matching clearance, capacity information, emptying design and pump preference to your trip. The 365 focuses the decision on fit and a piston pump, while the other options offer more stated tank details or a different flush style.
| Model | Useful distinction | Check before choosing |
|---|---|---|
| Thetford Porta Potti 365 | Piston pump; 8.8 lb | Tank capacities and indicator are not stated |
| Thetford Porta Potti 345 | 15 L flush-water tank; 12 L waste tank | Flush-water tank has no level indicator |
| Camco 5.3 Gallon | Detachable 5.3 gallon tank; bellows flush | 11.5 lb weight and 17 in height |
| Kohree 5.8 Gallon | Waste-level indicator; detachable tank | 14 lb weight and 16.3 in height |
The Thetford 345 is the clearest alternative when you want a shorter model with stated capacity details. Read the full Porta Potti 365 vs 345 comparison if those two are your finalists.
Camco is a fit for buyers who want a detachable holding tank and a bellows-style flush. Its 2.5 gallon top tank and 5.3 gallon holding tank are distinct capacities, so compare each one with your expected use.
Kohree suits buyers who want a visible waste-level cue and stated fresh-water and waste capacities. Its listed fresh-water capacity is 3.2 gallons and waste capacity is 5.8 gallons, but its 14 lb weight may matter if you'll carry it often.
What should you measure before buying the 365?
Measure the storage opening, usable floor area and full path from storage to the toilet's intended location. For the 365, allow for its 16.81 in depth, 15.08 in width and 16.3 in height, plus room to position it.
Check the route with other gear in place if you plan to keep the toilet in a packed camper or vehicle. A narrow turn or crowded doorway can be a bigger obstacle than the storage footprint itself.
Think through where the toilet will sit during use and where it will be stored between stops. Avoid placing it where a door, drawer or main walking path will be blocked.
If you need capacity figures to plan how often you'll empty it, confirm model 92820's tank capacities with Thetford before buying. The 365's capacity and indicator information are not stated here, so don't assume that another model's figures apply.
How do you set up and use a portable camping toilet?
Set up a portable toilet on a stable, level surface with enough space to sit, operate the flush and move it afterward. Read the model instructions before adding water or preparing the waste tank, because the details vary by model.
For the 365, use the piston pump as directed by its instructions and keep the toilet upright while moving it. Choose a location that gives you privacy and a clear route to the toilet; the guide to using a portable camping toilet walks through the basic routine.
Have your emptying plan ready before the tank needs attention. Know which disposal point is appropriate for your setup, and follow local rules and the toilet's instructions.
How should you care for a Porta Potti 365?
Follow Thetford's care instructions for cleaning and handling the 365, and use products that the manufacturer approves for the toilet. Keep the toilet upright during transport and clean spills promptly.
Avoid guessing at its capacity or waiting for a level indicator that may not be present. Since the 365's indicator information is not stated, use the manufacturer’s guidance for knowing when to empty it.
Plan a place to clean the toilet that has suitable drainage and won't contaminate a water source or campsite. The portable toilet emptying guide explains the steps to plan for and supplies that may help.
What mistakes should you avoid with the 365?
The biggest buying mistake is assuming the 365 has the same tank capacities or indicator as another Porta Potti model. Confirm any details that affect your trip with Thetford before purchase.
Another common mistake is measuring only the spot where the toilet will sit. Check the storage opening, doorway turns, usable floor area and access for cleaning and emptying.
Don't choose solely by weight or height. A lighter toilet can still be awkward to move through a tight route, and a shorter model can be a poor fit if its tank information or flush setup doesn't meet your needs.
Is the Thetford Porta Potti 365 the right choice for you?
Choose the Thetford Porta Potti 365 if its dimensions work, you want a piston-pump flush and you can make your plans without confirmed tank-capacity or indicator details. Choose the 345 for a shorter Thetford option with stated capacities, Camco for its detachable tank and bellows flush, or Kohree for its waste-level indicator and stated capacities.
Before deciding, measure both the storage spot and route, then make an emptying plan. For a broader comparison across formats, see the portable camping toilet guide.
