The picks first
No long preamble — here's what to buy. The Thetford Porta Potti 565E is the comfort gold standard: a real flushing cassette toilet with a sealed waste tank, a proper seat height and minimal odor, the one reviewers and long-trip campers keep recommending when comfort matters. If that's more toilet than you need, the Camco Portable Travel Toilet is the value flushing cassette — the same idea for less money.
If you want the cheapest, simplest, no-plumbing option, the Reliance Luggable Loo is a sturdy bucket with a real seat lid that takes biodegradable bags — under $30 and bombproof. Tight on cargo space? The TRoad Folding Commode collapses nearly flat and uses bags, packing into a gap a Porta Potti never would. And the TripTips unisex urinal is the cheap add-on that saves you the 2 a.m. trip into the rain.
If you're new to this, the whole category splits into two honest camps and almost everyone lands in one of them. Either you want a flush toilet that feels like home and you'll empty at dump stations (the Thetford or Camco), or you want a bag system that's cheap, light and disposable and you'll never have to empty a tank (the bucket or folding commode). There's no universally right answer — it depends on your trip length, your cargo space, and frankly your tolerance for the chore — but knowing which camp you're in narrows the whole decision to two products in about ten seconds.
- Flush cassette: Thetford Porta Potti 565E (comfort) or Camco (value).
- Bag/bucket: Reliance Luggable Loo (cheap) or TRoad folding commode (packs small).
- Add-on: a TripTips unisex urinal saves the 2 a.m. trip.
Why each earns its spot
The Thetford Porta Potti 565E is the comfort standard for a reason. It's a true flushing toilet in miniature: a fresh-water tank up top flushes into a sealed waste cassette below, a level indicator tells you when to empty, and the seat sits at a near-household height so it's comfortable for adults rather than a squat. With tank treatment, odor is genuinely a non-issue. It's the toilet long-trip campers and van dwellers stop complaining about, which is the highest praise in this category.
The Camco Portable Travel Toilet takes that same flush-cassette concept and trims it to a friendlier price. You give up a little refinement and seat height versus the Thetford, but the core experience — flush, sealed tank, dump-station emptying — is the same, which makes it the value pick for someone who wants a real flush toilet without the flagship cost.
The Reliance Luggable Loo is the honest budget answer and, for a lot of weekend campers, all the toilet they'll ever need: a sturdy five-gallon bucket with a proper snap-on seat lid that takes biodegradable waste bags. There's nothing to flush, nothing to empty at a dump station, and nothing to clean if you bag it — you simply seal the bag and pack it out. It's bulky in its bucket form, but you can store gear inside it in transit, and at around $25 it's almost free.
The TRoad Folding Commode solves the one problem the bucket can't: packed size. It collapses nearly flat into a slim case and unfolds into a sturdy seat frame that holds a waste bag, fitting into a cargo gap a Porta Potti or a bucket never would — the pick when trunk space, not money or comfort, is your binding constraint. And the TripTips unisex urinal is the cheap companion piece everyone's glad they brought: a sealed, spill-proof bottle that saves the cold, rainy 2 a.m. walk and takes the pressure (literally) off your main toilet so its tank or bag lasts longer.
The buying criteria that matter
Three things decide which is right for you:
- Flush cassette vs bag/bucket. A flushing cassette (Porta Potti, Camco) is the most comfortable and lowest-odor but needs emptying at a dump station and takes more space. A bag/bucket (Luggable Loo, folding commode) is cheaper, lighter and you toss the bag — simpler, slightly less pleasant.
- Packed size vs your cargo. A Porta Potti is a real box that eats trunk space; a folding commode disappears. Be honest about what your vehicle can spare.
- How long and how often you camp. Weekend trips and the occasional emergency suit a bucket or folding commode; longer trips and people who want genuine comfort justify the flushing cassette.
- Seat height and stability. A toilet you have to squat over or that tips when you sit is a toilet you'll dread. The Porta Potti's near-household seat height is its quiet advantage; a bucket sits lower and a folding commode needs a stable, locked frame. If anyone in your group has knee or mobility issues, this is the spec that matters most.
- Capacity for your group and trip. A cassette's waste tank is rated for a number of uses before it needs emptying — fine for two people over a weekend, tighter for a family or a longer trip. Bag systems sidestep this since you just add a bag, but you then carry more sealed bags. Match the system's between-empties capacity to how many people use it and how far you are from a dump station or trash.
A fifth factor people forget until they're at camp: privacy. A toilet you won't use in the open is no toilet at all, so plan where it goes. Many car campers pair any of these with a cheap pop-up privacy/shower tent, or use the tailgate with the hatch up and a towel for a screen. The folding commode and bucket are easy to carry a few steps from camp for privacy; the Porta Potti is heavier to relocate, so people tend to use it inside a privacy tent or the vehicle. Sort the privacy plan when you buy the toilet, not at the campsite.
How to actually use and empty one (the part nobody explains)
For a flushing cassette (Porta Potti, Camco): add water and a dose of tank treatment to the waste cassette before the trip — the treatment is what breaks down waste and kills odor, and skipping it is the number-one reason people think these toilets smell. Use it like a normal toilet, flush with the bellows or pump, and watch the level indicator. To empty, detach the cassette, carry it to an RV dump station or an approved toilet, and pour through the rotating spout (press the vent button so it doesn't glug back at you). Rinse, re-dose, done. Never empty cassette waste in nature or a storm drain.
For a bag system (bucket or folding commode): line it with a heavy-duty waste bag, and — this is the trick — add an absorbent gelling agent or even cheap cat litter, which solidifies liquid and controls odor so the bag isn't a sloshing mess. After use, twist, seal, and store the bag in a sealed container until you reach a trash receptacle that permits it. Double-bag for longer trips. The whole system lives or dies on the gelling agent; with it, a bag toilet is clean and nearly odorless, and without it, it's exactly as grim as people fear.
One universal tip across both types: keep a dedicated kit with the toilet — extra bags or a spare cassette-treatment bottle, hand sanitizer, a roll of toilet paper in a waterproof bag, and a few nitrile gloves for emptying. Having that kit packed means the toilet is genuinely ready to use the moment you need it, which is the difference between a system you rely on and one that becomes a problem at the worst possible time.
Common questions
How do you empty a Porta Potti? The waste cassette detaches and empties at any RV dump station or approved toilet; a flush of water and tank treatment keeps odor down. Do the bags smell? Bag systems with a gelling/odor agent control it well for short use; seal and pack out. Is a bucket really fine? For weekends, yes — millions of campers use one happily; comfort and odor are the only things you give up.
Verdict
Buy the Thetford Porta Potti 565E if comfort and low odor matter and you have the space — it's the toilet long-trip campers stop complaining about. Save money with the Camco if you want a flush for less. Go with the Reliance Luggable Loo if you want cheap, simple and bombproof, or the TRoad folding commode if your cargo space is the binding constraint. Add the TripTips urinal regardless — it's the cheapest comfort upgrade in this whole category. Match the type to your space and trip length and any of these solves the one problem no one likes to talk about.
If I had to pick a single best buy for the average car camper, it's the Porta Potti 565E — the comfort and low odor genuinely change how you feel about camping without facilities nearby, and people who buy a bucket first often upgrade to it later. But that's a real-money, real-space commitment, and there is zero shame in the bucket-and-bags route: it's what most weekend campers happily use, it costs almost nothing, and with a gelling agent it's cleaner than its reputation. Buy the level of comfort your trips justify, sort out a privacy plan, and you've quietly solved the thing that keeps a lot of people from camping where there's no restroom at all — which is the whole point.
Buy it, set it up once at home so it isn't a mystery in the field, pack the little kit of bags, treatment and sanitizer alongside it, and you'll forget it was ever an awkward subject. A portable toilet is one of those unglamorous purchases that quietly expands where and how long you can comfortably camp — far more than its modest price suggests.
Best single buy for most: the Thetford Porta Potti 565E. Tightest on space or budget: the folding commode or the Luggable Loo. Add a urinal regardless.
