The bags are sealed afterwards with a drawstring. He then double-bags them and keeps them in an old flare box until he’s ashore and can dispose of them in the household waste – as you would a child’s nappies. The robust Blue Diamond Nature Calls Composting Toilet takes loads up to 200kg. It has an integrated composter under the seat, which collects solids and allows them to decompose and slide downwards, to be removed via a flap as compost. A flushable camping toilet is on the more luxurious end of portable toilets. The Thetford’s Porta Potti range has some great portable flushing camping toilets that consist of two parts. The upper section is a combined flush-water tank and toilet bowl with a detachable seat and cover, and the lower section is the waste holding tank. The two sections come apart easily, allowing you to empty the waste conveniently and hygienically.

With the outer lid up, there is a proper toilet seat available inside which can be also lifted up if required. It then rests inside the outer lid neatly. If you’re limited on space, a collapsible camping toilet such as the Carplife Bivvy loo is a good idea, as this will fold up easily and include a seat and a waste bag. As mentioned many times on Camping Secrets, we love our little Mercedes campervan . However it does not have an on-board loo which can limit the places we can stay – step forward the Thetford Porta Potti Qube 335 which measures only 31.3 x 34.2 x 38.2 cm and works really well.Urine gets pumped out with a diaphragm pump but could go to a bottle if in a boatyard. Poop goes to separate container with bag and I use sawdust. No smell and easy to use and dispose of,” says Andrew. Space is a premium in boats and tents, so if you’re willing to squat a little lower, and empty/ fill the tanks more frequently, the Thetford Porta Potti 335 is about as compact as you can get for a flushing loo.

The toilet leaks as the rubber seal between the tank and seat don’t seal very well. If this is an issue, you can buy a Folding toilet. So, whether you’re weekending in a marina, alone on an anchorage, DIY-ing in a boatyard or camping with a trailer-sailer there’s a portable toilet for you. They are supplied in boxes of 20 and work out at just over 50p per bag,” he says. “The liner fits perfectly around the rim of the toilet bowl and comes with an absorbent gel pad which will absorb up to 600ml of urine.”At the top end of the market, Thetford’s Porta Potti 565 has an electric (battery-powered) flush or manual. They can be heavy when full, especially if you go for a camp loo with a large waste holding tank, you can pop them on a rolling trolley though if the carrying weight is a real problem. You must wear a mask on your face and gloves on your hands. These types of protective equipment will keep you safe from any infection and intolerable odors.
