Best Portable Toilets for Wild Camping and Off-Grid Adventures

Wild camping strips away the conveniences of a serviced campsite — including toilet blocks and chemical disposal points. If you regularly camp off-grid on remote Scottish hillsides, along coastal paths or at dispersed moorland spots, your toilet setup needs to be self-sufficient, lightweight and environmentally responsible. Here is what works best for wild camping in 2026.

The Off-Grid Challenge

When wild camping, you cannot rely on a nearby Chemical Disposal Point. This changes the equation in two ways:

1. You need to carry sealed waste with you until you reach a disposal facility, which may be days away.
2. The environmental impact of your toilet setup matters more — you are camping in sensitive, often protected landscapes.

Both factors influence which type of toilet suits off-grid use.

Composting Toilets — The Off-Grid Ideal

For van lifers, overlanders and anyone with a vehicle-based setup, a composting toilet is the strongest off-grid option. It uses no water, requires no chemicals, and produces no liquid black-water waste that needs disposal at a CDP. Solids decompose in a coconut-coir medium, and liquids are diverted to a separate container that can be diluted and disposed of responsibly in remote locations.

The main brands — Nature's Head, Separett and others — produce units designed for vehicle installation. A 12V fan vents the composting chamber, keeping the interior odour-free. The compost material needs changing every few weeks to months depending on use, and the result is a dry, inoffensive substance.

Pros for Wild Camping

• No chemical waste to dispose of at a CDP
• No water consumption
• Minimal environmental impact
• Long intervals between servicing

Cons for Wild Camping

• Requires vehicle installation (vent hose, 12V connection)
• Higher upfront cost
• Not practical for tent-based wild camping due to size and ventilation requirements

Compact Chemical Toilets — Practical for Tent-Based Wild Camping

If you wild-camp from a tent, backpack or kayak, a compact chemical toilet remains the most practical option. The Thetford Porta Potti 145 is the lightest in the Porta Potti range, with a 12-litre waste tank that is manageable to carry when sealed.

Blue Diamond's Standard portable toilet is even lighter and cheaper, making it a reasonable choice for occasional off-grid use where you accept the need to carry waste out.

Managing Waste Without a CDP

• The sealed waste tank on any quality portable toilet — Thetford, Dometic or Blue Diamond — is leak-proof when the spout cap and blade valve are closed. It can be transported safely in a vehicle boot.
• Plan your route to pass a campsite, service station or public facility with a CDP on your way home or at regular intervals.
• Use eco-friendly chemicals (Thetford Aqua Kem Green or Natural) to minimise the environmental impact of the chemicals within the sealed tank.

Dry Bag and Liner Systems

For ultra-lightweight wild camping where every gram counts, bag-and-liner toilet systems offer the simplest possible sanitation. These are essentially a folding frame with a seat that holds a lined bag. After use, add absorbent granules or powder, seal the bag and pack it out with your rubbish.

They are not as comfortable or hygienic as a flushing chemical toilet, but they weigh under a kilogram and take up almost no space. For high-mountain camping, multi-day hikes and kayak touring, they fill a genuine niche.

Leave No Trace Principles

Wild camping in the UK — particularly in Scotland, where it is a legal right under the Land Reform Act — comes with a responsibility to leave no trace:

1. Never bury or leave chemical toilet waste in the wild. Always carry it to a proper disposal point.
2. If using a cat-hole method (digging a hole for human waste without a chemical toilet), dig at least 15cm deep and at least 50 metres from any water source. Cover and disguise the hole afterwards.
3. Pack out all toilet paper and hygiene products — do not bury them.
4. Use biodegradable, eco-friendly products wherever possible.

Recommended Off-Grid Setup

• Vehicle-based: composting toilet permanently installed, supplemented by a lightweight Porta Potti 145 for use outside the vehicle with a toilet tent from Kampa.
• Tent-based: Thetford Porta Potti 145 or Blue Diamond Standard, eco-friendly chemicals, a pop-up toilet tent and a plan for waste disposal.
• Ultra-light: bag-and-liner system with absorbent granules and sealed bags for packing out.
