A camping toilet is a containment problem with a comfort overlay. The type decides how many uses it holds; the bag or cassette decides how you get rid of it; the odour control decides whether anyone uses it on day three. Choose by trip length and disposal options, not by seat height.
Types and where they fit
| Type | Capacity | Best for | Disposal |
|---|---|---|---|
| Bucket + wag bag | 5–15 uses | Backpacking, river trips | Pack out |
| Folding toilet | 5–10 uses | Car camping, emergencies | Pack out |
| Cassette (porta-potty) | 15–25 uses | Car camping, RV | Dump station |
| Composting | 30–50 uses | Cabins, long stays | Compost or dump |
| Chemical portable | 20–30 uses | Groups, events | Dump station |
For a family of four on a weekend, a cassette toilet is the practical choice: it holds the volume and dumps at a station. For backpacking, only a wag bag qualifies.
Capacity in uses
| People | One night | Two nights | Three nights |
|---|---|---|---|
| 2 adults | 8–10 uses | 16–20 | 24–30 |
| 2 adults + 2 kids | 12–16 | 24–32 | 36–48 |
| 4 adults | 16–20 | 32–40 | 48–60 |
Capacity figures assume liquid and solid combined, and they are optimistic: coffee and beer double the liquid volume. Add 30% to any estimate for a group that drinks in the evening.
Bag systems
| System | Cost per use | Notes |
|---|---|---|
| Wag bag (gel powder) | $1.50–3 | Absorbs liquid, seals |
| Double-bag with cat litter | $0.50–1 | Cheap, bulky |
| Compostable liner | $1–2 | Only where accepted |
| Cassette (no bag) | $0 | Needs a dump station |
Gel powder is what makes a wag bag work: it turns liquid into a solid so the bag can be sealed and carried without leaking.
Disposal
| Where | Rule |
|---|---|
| Developed campground | Dump station or vault toilet |
| Dispersed land | Pack out; burial only where allowed |
| River corridors | Pack out, always |
| Alpine and desert | Pack out |
| Composting toilet | Follow the host’s instructions |
Never put wag bags in a campground dumpster unless it is marked for it. Never bury a bag. The whole point of the bag is that it leaves with you.
Odour control
| Method | Effect |
|---|---|
| Gel powder | High |
| Baking soda layer | Medium |
| Ventilated seat | High |
| Keep the lid closed | High |
| Separate liquids | Very high |
| Empty daily | Very high |
The single biggest improvement is separating liquid from solid. A urine-diverting setup or a separate bottle for night use roughly halves the smell and doubles the usable capacity.
Leave No Trace rules
- Pack out all waste where required, which is most public land.
- Bury only where regulations allow, 6–8 in deep, 200 ft from water.
- Do not burn toilet paper.
- Use unscented products near the toilet, and store it away from the tent.
- Sanitise hands after every use; a bottle of gel lives with the toilet.
Cleanup steps
| When | Action |
|---|---|
| After each use | Close the lid, wipe the seat |
| Daily | Empty or check the bag, add powder |
| End of trip | Empty, rinse, disinfect, dry fully |
| Storage | Lid open, no bag, dry |
A cassette left closed and damp between trips grows mould in the seal and smells permanently. Dry it open, in shade, for a full day.
Setting it up at camp
| Step | Action |
|---|---|
| 1 | Choose a spot 200 ft from water and 50 ft from the tent |
| 2 | Level the ground or use a flat board |
| 3 | Set privacy: a tarp, a windbreak, or a dedicated corner |
| 4 | Put paper, powder, and hand gel in a sealed box next to it |
| 5 | Mark it clearly so nobody walks into it at night |
| 6 | Agree on the night-time procedure before dark |
The night-time procedure is the detail that decides whether the toilet gets used. A headlamp left on top of the box and a clear path are worth more than a better seat.
Winter and long stays
| Situation | Adjustment |
|---|---|
| Below freezing | Cassette freezes; use bags |
| Rain | Shelter the seat, keep paper dry |
| Long stay (5+ nights) | Plan an emptying trip |
| Group of 6+ | Two units, or a cassette plus a bucket |
| High altitude | Liquid expands; empty more often |
A cassette that freezes cracks at the valve. In winter, either keep it inside a heated space or switch to wag bags.
Cost of the options
| Setup | Cost |
|---|---|
| Bucket + 20 wag bags | $40–70 |
| Folding toilet + bags | $60–110 |
| Cassette toilet | $130–250 |
| Composting toilet | $300–900 |
| Chemical portable, group | $150–300 |
The cassette is the break-even point: at 20+ uses a trip, bags cost more than the cassette within two seasons.
Where to place it in camp
Downhill from the water and the tent, screened from the main path, and within easy reach at night. Fifty feet from the tent is the usual compromise between privacy and willingness to use it in the dark.
What people get wrong
| Mistake | Consequence |
|---|---|
| Buying capacity by seat comfort | Emptying twice a day |
| No gel powder | Leaks in the car |
| Burying wag bags | Animals dig them up |
| Using scented chemicals | Attracts animals, masks nothing |
| Leaving it in the sun | Plastic warps, smell increases |
