Sanitation is the emergency-prep category people forget until the water main breaks, the sewer backs up after a flood, or a multi-day power outage knocks out the well pump. A portable toilet bridges that gap: it lets your household stay clean and disease-free when the plumbing is down, and it does double duty for camping, van life, RVs, boats, and job sites the rest of the year.

We tested and compared the leading models across flush type, holding-tank capacity, odor control, weight, and how well each one fits an emergency preparedness kit. Below are the six that earned a spot, each chosen for one clear role.

Why You Need a Portable Toilet for Emergencies

Modern flush toilets are useless the moment they lose water pressure or a sewer line backs up. According to the EPA, standard toilets use about 1.6 gallons per flush (older models up to 6 gallons), so even one "normal" flush wastes scarce stored water during an outage — and if the sewer itself is compromised by flooding, flushing can push contaminated water back into your home.

The CDC's emergency-sanitation guidance is explicit: if your toilet is not working, use a portable camping toilet, or line the toilet bowl with a heavy-duty plastic bag, and never dispose of human waste where it can contaminate drinking water. FEMA's Ready.gov disaster-supply lists similarly recommend storing a plastic bucket with a tight lid plus garbage bags as basic sanitation backup. A purpose-built portable toilet simply does this job better — with a real seat, a sealed tank or bag, and odor control.

Good emergency sanitation pairs naturally with the rest of your kit: store it alongside your emergency water storage, portable power station, and blackout kit so everything is in one place when the grid goes down.

Best Portable Toilets Compared

Top Portable Toilets Reviewed

1. Thetford Porta Potti 565E Curve — Best Overall

The Thetford Porta Potti 565E Curve is the model most camping and RV reviewers treat as the benchmark, and it's our top pick for emergency use too. Per Thetford, it carries a 5.5-gallon (21-liter) sealed waste-holding tank and roughly 4 gallons of fresh water, good for about 56 flushes before you need to empty it.

Key Features:

• Battery-powered electric flush (push button, even rinse)
• 5.5 gal waste tank with sealed slide valve and pressure-release vent
• Tank-full level indicator so you don't overfill
• Comfortable near-residential seat height
• Rotating pour-out spout for clean emptying

Best for: Households that want a genuinely comfortable, low-odor toilet for both camping and a multi-day water or sewer outage. The level indicator and sealed tank make it the easiest to live with day to day.

2. Camco Portable Travel Toilet (5.3 gal) — Best Value

The Camco Portable Travel Toilet is the perennial Editor's-Choice value pick. It uses a simple, durable bellows pump flush, a 5.3-gallon detachable waste tank, and a sliding gate valve for odor control — all at a price well below the electric units.

Key Features:

• Manual bellows pump flush (no batteries to die)
• 5.3 gal waste tank, 2.5 gal fresh-water tank
• Sealing slide valve locks in odor between uses
• Side latches secure the upper tank to the base for carrying

Best for: Budget-minded preppers and campers who want a real flush toilet without electronics. The manual pump is one less thing to fail in an emergency.

3. Reliance Luggable Loo — Best Budget / Emergency Bucket

When the priority is dead-simple reliability during a grid-down event, the Reliance Luggable Loo is hard to beat. It's a 5-gallon bucket with a snap-on toilet seat lid, weighs about 3 pounds, and costs under $50 — and it needs zero fresh water.

Key Features:

• Standard-size snap-on seat and lid on a 5-gallon bucket
• Works with double liner bags + a solidifying gel or kitty litter
• Nests inside other gear; stores flat with your supplies
• Doubles as a storage bucket until needed

Best for: Home shelter-in-place sanitation and pack-out trips. Because capacity is limited only by how many liner bags and absorbent packets you store, it scales to long, open-ended outages better than any tank toilet. Stash a box of waste bags with solidifying gel next to it.

4. Dometic 972 Portable Toilet — Best Premium

The Dometic 972 Portable Toilet upgrades the experience with an easy push-button pump flush that's far less stiff than the cheap bellows pumps, plus the rugged construction Dometic is known for. It pairs a 2.5-gallon waste tank with a 2.5-gallon fresh tank in a compact, sturdy shell.

Key Features:

• Smooth push-button water pump (low effort to flush)
• 2.5 gal waste / 2.5 gal fresh, detachable lower tank
• Heavy-duty latches and reinforced base
• Sealed valve and ergonomic carry handle

Best for: Buyers who value build quality and an effortless flush over maximum tank size — great for boats, vans, and frequent campers who'll use it year-round.

5. Cleanwaste GO Anywhere Toilet System — Best for Pack-It-Out / Go-Bag

For wilderness trips, disaster go-bags, and any place you must carry waste out, the Cleanwaste GO Anywhere Toilet System is the standard. It's a sturdy folding frame at normal seat height that holds a sealable "WAG" waste bag containing a gelling and deodorizing powder.

Key Features:

• Folds flat to roughly a briefcase size; sets up in seconds
• Holds up to ~300 lb on a stable steel frame
• GO Anywhere bags gel liquid, kill odor, and are landfill-approved
• No water, no tank to dump — bag in, seal, pack out

Best for: Backpackers, overlanders, and anyone who wants a compact sanitation option in a bug-out bag. Pairs well with the rest of your 72-hour kit.

6. SereneLife Outdoor Portable Toilet — Best Compact Flush

The SereneLife Outdoor Portable Toilet is a lightweight, lower-cost flush unit with a 3.2-gallon waste tank and matching fresh tank. It's a good middle ground for people who want a flush toilet that takes up less space than the full-size Thetford and Camco models.

Key Features:

• Bellows pump flush with a 3.2 gal waste tank
• Compact, light shell for small tents, cars, and closets
• Level indicator and sealed slide valve
• Easy-detach lower tank with pour spout

Best for: Apartments, small vehicles, and storage-limited homes that still want a true flush toilet for occasional outages and weekend trips.

How to Choose a Portable Toilet

Flush Type

• Bucket (no water): Most reliable in a true emergency — nothing to break, no water needed. Relies on liner bags + absorbent.
• Manual bellows / piston pump: Simple, no batteries; can be stiff on cheaper units.
• Battery/electric flush: Most comfortable and consistent, but keep spare batteries with your kit.

Capacity vs. Users

A 5+ gallon waste tank gives two people 2-3 days between dumps; smaller 2.5-3 gal tanks fill in about a day for a couple. For long or open-ended outages, a bucket toilet with a deep supply of bags often beats a fixed tank because you're never stuck waiting for a dump station.

Odor Control & Chemicals

Look for a sealed slide valve (flush units) or a tight-snapping lid (buckets), and always use the matching holding-tank deodorizer or a solidifying gel. Skipping the chemical is the number-one cause of smell complaints.

Disposal Plan

Decide in advance where waste goes: flush units empty into a sewer-connected toilet or RV dump station; bucket/WAG-bag systems get double-bagged and trashed per local rules. Following the CDC's guidance keeps your household and water supply safe.

Frequently Asked Questions

What kind of portable toilet is best for a power or water outage at home?

For shelter-in-place emergencies, a bucket-style toilet like the Reliance Luggable Loo is the simplest and most reliable option. It needs no fresh water, uses a heavy-duty liner bag plus a solidifying or kitty-litter-style absorbent, and stores flat with your other emergency gear. If you want more comfort for a multi-day outage, a flush-style cassette toilet such as the Thetford Porta Potti 565E adds a sealed holding tank and odor control.

How long does a portable toilet holding tank last before it needs emptying?

It depends on tank size and the number of users. A 5.5-gallon (21-liter) waste tank like the one on the Thetford Porta Potti 565E delivers roughly 56 flushes per fill, which is about 2-3 days for two people using it only for the essentials. Bucket-style toilets are limited only by how many liner bags and absorbent you have stored, which makes them better for long, uncertain outages.

Do portable toilets smell?

A quality portable toilet with a sealed waste valve and the correct holding-tank chemical (or a solidifying gel in bucket models) controls odor very well for days at a time. Smell problems almost always come from skipping the chemical, leaving the seal valve open, or letting the tank get overfull. Empty the tank before it reaches capacity and rinse it after each dump.

What chemicals do I need for a portable flush toilet?

Add a holding-tank deodorizer (liquid or drop-in sachet) to the lower waste tank to break down solids and control odor, and optionally a rinse/blue additive to the upper fresh-water tank. Many newer formulas are biodegradable and formaldehyde-free, which matters if you plan to dump into a septic system or an approved dump station rather than a sewer.

Where can I legally empty a portable toilet?

Empty cassette and flush portable toilets into a regular flush toilet connected to a sewer or septic system, or at a designated RV dump station. Never dump waste on the ground, into storm drains, or near any water source. For bucket toilets that use sealed bags and solidifier, double-bag the waste and dispose of it in the trash where local rules allow, following CDC emergency-sanitation guidance.

Are portable toilets okay for backpacking and pack-it-out areas?

For trips where you must pack out human waste, a folding frame system like the Cleanwaste GO Anywhere with WAG-style sealable waste bags is the standard choice. The bags contain a gelling and deodorizing powder, seal airtight, and are landfill-approved, so you can carry waste out without odor or leakage.

The Bottom Line

If you want one toilet that handles both weekend camping and a multi-day emergency, buy the Thetford Porta Potti 565E — its big sealed tank, level indicator, and clean flush make it the most livable choice. If your only goal is grid-down readiness on a budget, the Reliance Luggable Loo plus a stash of gel waste bags is the cheapest insurance in prepping. Either way, store it now: the CDC and FEMA both list emergency sanitation as a core supply, and it's the one item you can't improvise comfortably once the water is off.
