Quick Tips
Add a capful of RV holding tank treatment before the first use — it breaks waste down and kills odor at the source, not just masks it.
Empty the waste tank before it hits 75% full; a nearly-full tank is heavy, awkward, and much more likely to splash on the dump.
Store your portable toilet with the slide valve open and the tanks dry — a closed damp tank breeds mold and permanent odor in less than a week.
Use RV-safe toilet paper only — standard paper doesn't break down and will clog the slide valve on piston-flush models within a few uses.
Thetford Porta Potti 565E Curve Portable Toilet
Best for car campers who want a real home-toilet experience
Thetford Porta Potti 565E Curve Portable Toilet
Best for car campers who want a real home-toilet experience
What we like
- Battery-powered electric flush delivers consistent bowl coverage with almost no effort from the user.
- Tall, home-like seat height makes it genuinely comfortable for extended basecamp use.
- Integrated toilet paper holder keeps paper clean and within reach without a separate holder.
- Built-in level indicators for both the fresh water and waste tanks eliminate guesswork on multi-day trips.
What we don't
- Electric flush requires 6 AA batteries that drain faster than you expect in cold temperatures.
- Premium price puts it out of reach for campers who only go out a few times a year.
- At 5.5 gallons of waste capacity, it still needs emptying every 2-3 days for two adults.
The 565E is the toilet that makes first-time users forget they're camping — the electric flush, tall seat, and paper holder combined feel closer to a home bathroom than any other portable unit at this price. If your camp setup includes a tent or screen shelter with an actual toilet area, this is the one that earns its footprint.
This is built for car campers, overlanders, and basecamp hunters who aren't counting ounces and want to stop thinking about the bathroom situation entirely. If you're splitting the cost between two or more people on a regular camping group, the price-per-use math works strongly in its favor.
Camco 5.3-Gallon Portable Toilet (41541)
Best for budget-conscious campers who want a proven flush system
Camco 5.3-Gallon Portable Toilet (41541)
Best for budget-conscious campers who want a proven flush system
What we like
- Bellows-type flush system has no moving parts to break and works reliably in any temperature.
- 5.3-gallon waste tank handles a full 3-day weekend trip for two adults without emptying.
- Detachable holding tank with sealed slide valve locks odors in completely during transport.
- Comes with TST orange drop-in tank treatment samples so you're ready to use it on day one.
What we don't
- No tank level indicator means you're guessing how full the waste tank is without checking manually.
- Bellows flush is less thorough than electric or piston flush and may need a second pump on solid waste.
- Older design means the seat height is lower than modern competitors, which some adults find uncomfortable.
The Camco 41541 has been the default recommendation in RV and camping forums for over a decade because it simply works — the bellows flush is reliable, the 5.3-gallon tank lasts a weekend, and the sealed slide valve doesn't leak. At roughly half the price of the Thetford 565E, you're giving up the electric flush and the level indicator but not much else that matters in the field.
This is the pick for anyone who wants a functional flush toilet without overthinking it. If you camp a few weekends a year and want something that lives in the truck without taking up mental space, the 41541 is it.
Thetford Porta Potti 365 Portable Toilet
Best for campers who want Thetford quality without the electric flush price
Thetford Porta Potti 365 Portable Toilet
Best for campers who want Thetford quality without the electric flush price
What we like
- Piston pump flush is more powerful and thorough than bellows-type flush for better bowl cleaning.
- Built-in level indicators for both tanks make it easy to manage on multi-day trips.
- Same reliable Thetford sealing system and build quality as the premium 565E at a lower price.
- Pivoting pour-out spout makes dumping the waste tank cleaner and less awkward than most competitors.
What we don't
- Piston flush is more work per use than the electric 565E, which some users find annoying over time.
- No integrated toilet paper holder requires a separate solution to keep paper accessible and dry.
- Seat height is slightly lower than the 565E Curve, which makes a noticeable difference on longer use.
The 365 sits in the exact middle of the Thetford lineup — you get the same sealed slide valve, level indicators, and pivoting dump spout as the flagship 565E, but the piston flush replaces the electric motor, dropping the price by about $70. That's the entire value proposition, and for most campers it's a genuinely good trade.
If you want the Thetford build quality and the tank indicators but don't want to rely on batteries in the field, the 365 is the smarter buy than the 565E. Families or groups who camp regularly and want one toilet that handles everything without fuss will find it covers every situation.
Dometic 5.0-Gallon Portable Toilet
Best for RV campers and van lifers who want a compact pressurized flush
Dometic 5.0-Gallon Portable Toilet
Best for RV campers and van lifers who want a compact pressurized flush
What we like
- Push-button pressurized flush delivers a powerful one-handed rinse with under 1 pint of water per flush.
- Prismatic level indicator reads accurately even in low light, which matters inside a van or dark tent.
- Compact footprint fits tighter spaces than comparably specced Thetford models.
- Low water use per flush extends fresh tank life significantly on longer trips.
What we don't
- Heavier than comparable 5-gallon options at 13.1 lbs empty, which matters if you're moving camp frequently.
- Higher price than the Camco for similar tank capacity puts it in a more competitive tier.
- Some users report the slide valve requires more force to open than Thetford equivalents after extended use.
The Dometic earns its place for one specific reason: the pressurized push-button flush uses less than a pint of water per flush, which extends how long you go between refilling the fresh tank — critical in a van or truck camper where water is limited. The prismatic level indicator reading clearly in low light is a small detail that matters more than it sounds when you're using this inside a dark vehicle.
This is the pick for van lifers and truck campers where space and water efficiency matter more than seat height or premium features. Weekend car campers will be happy with the Camco at half the price — but if you're living out of a vehicle, the Dometic's efficiency math works in your favor over a season.
SereneLife Portable Toilet 5.3 Gal
Best for first-time buyers who want maximum capacity at minimum cost
SereneLife Portable Toilet 5.3 Gal
Best for first-time buyers who want maximum capacity at minimum cost
What we like
- Lightest option in the roundup at 9.5 lbs empty, easy to pull out of storage and move around camp.
- Push-button flush is simple to use and provides reasonable bowl coverage for the price tier.
- 3-way rinse system helps clean the bowl more thoroughly than single-outlet flush designs at this price.
- No-splash rotating disposal spout makes emptying less unpleasant than on toilets without one.
What we don't
- No tank level indicator means you have to remember how many times you've flushed or open the tank to check.
- Build quality is noticeably less robust than Thetford and Camco options — not a lifetime purchase.
- Slide valve seal on some units is reported to loosen over time with heavy use.
The SereneLife is the entry ticket — if you've never camped with a flush toilet and want to find out if it's worth the upgrade before spending $150 on a Thetford, this is where to start. The 5.3-gallon waste tank is legitimately useful, the push-button flush works, and the no-splash dump spout makes emptying tolerable.
Buy this if you camp a couple times a year and aren't ready to commit to a premium unit. If you camp six or more weekends a season with a partner, the Camco 41541 is worth the extra $20 for better build quality and a more reliable seal — but the SereneLife handles occasional use cleanly.
What to Look For
Tank capacity is the first number to look at before anything else. A 5-gallon waste tank handles roughly 50 flushes, which covers two people for about 3 days without emptying.
Drop below 3 gallons and you're emptying every day — fine for solo overnights, miserable for groups. Flush type determines how well the bowl actually gets clean.
Electric flush (battery-powered) delivers more pressure and a more thorough rinse, closer to a home toilet feel. Piston and bellows flush are manual, quieter, and never need batteries — the better choice for remote trips where you can't recharge.
The seal system is what separates a usable toilet from a tent-ruining disaster. Look for a double-sealed slide valve on the waste tank — it holds odors in when closed and releases cleanly when you rotate the pour spout to dump.
Cheap single-seal valves start leaking by trip three.
Who Should Skip This
If you're doing ultralight backpacking, none of these belong in your pack — even the lightest option here weighs 9 lbs empty and isn't designed for trail carry. Canoe-in or horse-pack basecamp hunters with strict Leave No Trace rules in designated wilderness areas should check local regulations before assuming a portable toilet is the right solution.
Anyone planning to camp exclusively at developed sites with vault toilets or full hookups probably doesn't need to spend money here.
What the Community Actually Uses
On r/CampingGear, the flush toilet question comes up constantly in pre-season threads — the consensus is almost always that the Thetford Porta Potti line is the benchmark everything else gets measured against, but members in the budget threads regularly point out that the Camco 41541 delivers 90% of the experience at half the price. The one thing the community agrees on universally: never skip the holding tank treatment.

Check Price on AmazonFrequently Asked Questions
How often do I need to empty a portable camping toilet?
For two adults, plan to empty a 5-gallon waste tank every 2-3 days. Solo campers can stretch it to 4-5 days. The level indicator on most modern units tells you when you're approaching full — don't ignore it, because a full tank is heavy and difficult to carry without spilling.
Can I use regular toilet paper in a camping toilet with flush?
No — use RV-safe or marine-grade toilet paper only. Standard toilet paper doesn't dissolve and will clog the slide valve or piston pump after a few uses. RV toilet paper is widely available and dissolves in minutes on contact with water.
Do portable flush toilets smell?
A properly maintained portable toilet with a sealed slide valve and holding tank treatment is effectively odor-free during use. Most odor problems come from skipping the tank treatment, not emptying before the tank is full, or storing the toilet with a wet, closed tank between trips.
What's the difference between an electric flush and a piston flush?
Electric flush (like the Thetford 565E) uses battery-powered pressure for a more thorough bowl rinse with less effort. Piston flush is manual — you pump a handle to push water through. Piston flush works without batteries and tends to last longer, but requires a bit more effort per flush.
Where do I empty a portable camping toilet?
The best options are campground dump stations, RV dump stations, and vault toilet waste receptacles — many are designed to accept portable toilet waste. Never dump into a regular trash can or on the ground. Check the campground's regulations before your trip, as some areas restrict dumping locations.
Buying Guide
You want a tank big enough to last the trip, a flush that actually cleans the bowl, and a seal that locks odors in when you close the valve. For two people on a 3-day trip, a 5-gallon waste tank hits the sweet spot.
Electric flush adds comfort but needs batteries. Piston flush works anywhere.
