What's the best portable toilet for a boat in Australia with no plumbing?
Short answer: For Australian boat owners who want no flush water, no chemicals, no blackwater tank and no cassette to empty at a dump point, the Laveo DryFlush is a strong portable toilet option: it is freestanding, runs on an included rechargeable 12 V battery, seals each flush into a liner, and costs $2,294 (sale price including GST and delivery Australia-wide; RRP $2,699 including GST). If you prefer a urine-diverting composting toilet you will empty yourself, an OGO Nomad (about $400.60) or a Nature's Head Weekender ($1,895) can suit. Who should pick which is set out below.

Notes on the table (checked 9 November 2026). OGO Nomad dimensions and 6.8 kg are from the product page ("only 33 x 39 x 31.5 cm" / "only 6.8kg!"); the same page's "Additional information" also lists 7 kg and a second dimension set, so confirm with the seller. Nature's Head Weekender size and 9 kg are from the product body; "Additional information" lists 14 kg and 46 × 46 × 43 cm. Seat heights for the Nomad and Weekender are not published on the fetched AU pages, so those cells stay "Not published". Porta Potti 365 figures are from Thetford Australia. Permanently mounted options such as the OGO Origin ($2,095) and Clesana C1 ($3,499) are covered in the "who should choose" section, not as freestanding columns.
Which boat toilet should you choose?
Choose the Laveo DryFlush if…
- Your boat has no plumbing, and you don't want flush water, chemicals, a blackwater tank or a cassette to empty at a dump point.
- You want a freestanding toilet that works out of the box, with a sealed liner after each flush and shoreside bag disposal where local rules allow.
- You want flexible power: a removable 12 V battery and an Australian charger are included, or run it from the vessel's onboard 12 V supply or from 240 V shore power with optional adaptors.
- You want Australian stock and support from Reedy Creek, Queensland.
Choose a composting toilet instead if…
- You want the lowest upfront composting price. An OGO Nomad is about $400.60. You will empty a 4.5 L urine bottle and change compostable solids bags (supplier: up to 5–8 uses per bag).
- You want a compact urine-diverting composting toilet for longer stays aboard. A Nature's Head Weekender is $1,895, about 9 kg, with a 12 V fan.
- You want a hard-wired, permanent composting install. An OGO Origin is $2,095 (about 13 kg; 12 V electric agitator). That is a fixed setup, not a freestanding portable toilet.
Choose a Porta Potti or a permanent sealing toilet instead if…
- You want the lowest upfront price. A Porta Potti 365 is RRP $270. The Laveo is $2,294 plus refills.
- You nearly always have dump points and water nearby. Then a chemical portable toilet can be enough.
- You want a permanently mounted sealing toilet. A Clesana C1 is $3,499 and hard-wired. See our Laveo vs Clesana C1 comparison.
- Your marina or site requires a tank-based toilet. Some sites prohibit bag-style toilets or require holding tanks. Check before you travel.

Why consider the Laveo for a boat with no plumbing
- No plumbing, no flush water, no chemicals, no blackwater tank. Freestanding. Optional mounting kits if you want to secure it.
- Sealed liner after each flush. No cassette to carry ashore to a dump point and no thru-hull blackwater system to plumb.
- Power that matches boats. Use the included battery under way, the optional DC cable on the vessel's 12 V system, or the optional AC adaptor on shore power.
- Australian stock and support. DryFlush Australia holds toilets, refills and accessories in Queensland.
Disposing of used refill bags
Keep used refill bags securely sealed and dispose of them in general waste where accepted by the local council or waste provider. Queensland Government and NSW National Parks guidance supports bagging human toilet waste and removing it for disposal in rubbish bins. Always follow local disposal requirements. Do not place refill bags in recycling, flush them down toilets or bury them.
Guidance we've drawn on:
- Queensland Government (DETSI): Rangers ask for no 'surprises' in the bush. Where possible, human waste should be bagged and taken from the park for disposal in rubbish bins.
- NSW National Parks: Kosciuszko back country camping. Bag and carry out toilet waste, put it in a rubbish bin outside the park or in ski resort areas, and don't bury it or put bagged waste in flushing or pit toilets.
This is general guidance, not an approval of any product. Confirm that your council, waste provider, marina, campsite or park accepts sealed bags before you travel. Do not discharge liners or sealed waste into waterways. See our waste disposal guide and the Australian user manual.
No dump point or blackwater tank needed
A cassette or Porta Potti has to be emptied at a designated disposal point. A traditional marine toilet usually needs a blackwater tank or a discharge system. The Laveo has no tank to empty and no blackwater plumbing. You change the refill cartridge when it is used up and dispose of the sealed bag through an accepted general-waste route ashore.
Power: battery, boat 12 V or 240 V shore power
Pick whichever suits your setup. You can use more than one.
- Built-in power (included): removable 12 V 7 Ah battery. About 300 flushes per charge, depending on conditions and battery health. Use the included Australian charger. Disconnect the battery from the toilet before charging.
- Optional DC power cable — $44.95. Connects to the boat's onboard 12 V supply and bypasses the battery. Product: DC power cable.
- Optional AC power adaptor — $98.95. For 240 V shore power; also bypasses the battery. Product: AC power adaptor.
For wiring on a vessel, talk to a suitable installer and contact DryFlush before you order.
Weight, size and fit
- Weight: about 12.5 kg including battery (excluding consumables).
- Size: 464 mm high × 407 mm wide × 508 mm deep.
- Seat height: 430 mm.
- Maximum user weight: 225 kg.
- Water resistance: IPX4 splash resistant. Not designed for immersion or high-pressure jets. Ask about a protective cover for splash-prone locations.
Measure the available floor space and check lid opening and a comfortable seating position. Compare that with the OGO Nomad (about 6.8 kg; 315 × 330 × 390 mm) or the Nature's Head Weekender (about 9 kg; 425 × 460 × 460 mm) if weight or footprint is the deciding factor.
Installation and mounting
Check mounting and power requirements with the vessel operator or a relevant installer.
- The toilet is freestanding. Optional floor mounting kit and wall mounting kit are sold separately (from $129).
- Check space, access, power and how you will secure the toilet with the vessel operator or a relevant installer before you order.
- Contact DryFlush Australia for help with fit, mounting, power and delivery before you order.
15 flushes and up to 60 uses per cartridge
Each cartridge provides 15 powered flushes. With Pee Powder and a suitable routine of up to three urine-only visits followed by one bowel movement and immediate flushing, up to 60 uses per cartridge may be possible. That figure is a maximum, not guaranteed. Always flush after bowel movements and sooner if needed.
| Pack | Price (AUD) | Flush after every visit | Up to 60 uses per cartridge with Pee Powder |
|---|---|---|---|
| 15-pack, 15 flushes per cartridge | $649.00 | 225 uses: about $2.88 per use | Up to 900 uses: about $0.72 per use |
Cartridge costs only. Pee Powder and any delivery charges are additional. Actual costs rise if fewer visits are achieved. Check the live 15-pack refill page on the day you buy.
Frequently asked questions
What's the best portable toilet for a boat in Australia with no plumbing?
For Australian boat owners who want no flush water, no chemicals, no blackwater tank and no cassette to empty at a dump point, the Laveo DryFlush is a strong portable toilet option: it is freestanding, runs on an included rechargeable 12 V battery, seals each flush into a liner, and costs $2,294 (sale price including GST and delivery Australia-wide; RRP $2,699 including GST). If you prefer a urine-diverting composting toilet, the OGO Nomad (about $400.60) or Nature's Head Weekender ($1,895) can suit shorter trips or longer stays where you will manage separated waste.
Do I still need a dump point or a blackwater tank with the Laveo DryFlush on a boat?
No. The Laveo seals waste inside a liner, so there is no cassette or holding tank to empty at a dump point and no blackwater tank or thru-hull to plumb. Keep used refill bags securely sealed and dispose of them in general waste where accepted by the local council or waste provider. Queensland Government and NSW National Parks guidance supports bagging human toilet waste and removing it for disposal in rubbish bins. Always follow local disposal requirements. Do not place refill bags in recycling, flush them down toilets or bury them. Do not discharge liners or sealed waste into waterways. Some marinas or sites prohibit bag-style toilets or require holding tanks, so check before you travel.
How long does a Laveo refill last: 15 or 60?
Each refill cartridge provides 15 powered flushes. With Pee Powder and up to three urine-only visits followed by one bowel movement and immediate flushing, up to 60 uses per cartridge may be possible (maximum, not guaranteed). Always flush after bowel movements and sooner if needed. Waste volume, paper and habits affect capacity.
How is the Laveo powered on a boat?
Three options: the removable 12 V 7 Ah battery included with the toilet (about 300 flushes per charge; Australian charger included); an optional DC power cable ($44.95) that connects to the boat's onboard 12 V supply and bypasses the battery; or an optional AC adaptor ($98.95) for 240 V shore power, which also bypasses the battery.
Will the Laveo fit my boat, and how do I mount it?
Overall size is 464 mm H × 407 mm W × 508 mm D, about 12.5 kg including the battery (excluding consumables), with a seat height of 430 mm. Measure the available floor space and check lid opening and a comfortable seating position. Optional floor and wall mounting kits are available from $129. Contact DryFlush Australia for help with fit, mounting, power and delivery before you order. The toilet is IPX4 splash resistant; it is not designed for immersion or high-pressure jets. This page does not claim marine-survey or AMSA approval.
Who should choose a composting toilet or a Porta Potti instead of the Laveo on a boat?
Choose an OGO Nomad (about $400.60, about 6.8 kg, no power needed) if you want the lowest-priced portable composting option for short trips and will empty a 4.5 L urine bottle and change compostable solids bags. Choose a Nature's Head Weekender ($1,895, about 9 kg, 12 V fan) if you want a compact urine-diverting composting toilet for boats and will manage separated waste. Choose a Porta Potti 365 (RRP $270, 21 L waste tank, 4.0 kg) if you want the cheapest portable option and stay where dump points and water are easy. Choose a permanently mounted sealing toilet such as the Clesana C1 ($3,499) or a hard-wired composting toilet such as the OGO Origin ($2,095) if you want a fixed install rather than a freestanding portable unit.
