Best Camping Toilet UK (2026): 4 Top Picks for Every Budget
Let’s be honest: the weakest part of most UK camping trips is the late-night loo situation. Across a rainy week in the Lake District or a muddy festival weekend, nothing kills the mood faster than stumbling around in the dark. The good news? A decent camping toilet costs a fraction of what you’d spend on one night of glamping and transforms the whole trip. This guide compares the best camping toilets to buy in the UK in 2026 — the four models that consistently dominate owner reviews and retailer rankings.
A quick note on how we work: we’re a research-based site. We analysed manufacturer specifications, verified owner reviews and expert commentary from outdoor publications to put this guide together — we haven’t lab-tested these units ourselves, so every recommendation below is grounded in published data and the consensus of people who live with these toilets on real campsites.
Quick Picks
- Thetford Porta Potti 365 — Best overall: pump-flush comfort, 21-litre waste tank, built-in level indicator, brilliant for families. Typically around £150–£175.
- Trelino Evo S — Best dry toilet: no chemicals, separates urine and solids, compact and surprisingly odour-free. Typically around £220–£260.
- Thetford Porta Potti 165 — Best value: the same trusted flush design in a smaller, more affordable package. Typically around £80–£110.
- Separett Weekend 7010 — Best for permanent installations: fan-assisted ventilation sets it apart from rival dry toilets. Typically around £280–£320.
Cassette, chemical or dry: know your camping toilet types
Before we get into the individual models, it helps to understand what’s actually on the market. True cassette toilets are plumbed units fitted into caravans and motorhomes — this guide is about portable camping toilets you can throw in the boot. These fall into two broad families.
Flushable chemical toilets work like a mini version of a domestic loo. A fresh-water tank feeds a hand-pump flush, and waste drops into a sealed lower tank pre-dosed with a chemical formula that breaks down waste and suppresses odour. The Thetford Porta Potti range is the benchmark here — it’s the design every budget rival copies.
Dry separation toilets take a different approach. They’re designed to keep urine and solids apart: liquid drains into a removable container, while solids drop into a chamber where a dry cover material (usually coconut fibre) zaps moisture and smell. The Trelino Evo S and Separett Weekend 7010 are the two most respected names in this category. No water, no chemicals, and the solids can often be composted rather than tipped into a chemical disposal point.
Both systems work; the right one depends on your camping style. Flush toilets feel more familiar and are quicker to empty at campsite disposal stations. Dry toilets win on environmental impact and the fact that you never carry blue chemical fluid around. We’ll cover the practical trade-offs in the buying guide further down.
How to choose a camping toilet
Capacity and the weight trade-off
The most important spec to check is the waste-tank capacity, because it dictates how often you’ll need to find a disposal point. A 21-litre tank will last a family of four a long weekend; a 12-litre tank will likely need emptying daily under the same load. But capacity comes at a cost in weight: water is heavy (a litre weighs exactly 1 kg), and a fully loaded flushable toilet can weigh as much as a small child. Always check the full-load weight, not just the empty figure, if you plan to lift the unit in and out of a vehicle boot.
Chemical vs. dry: the disposal question
Flushable toilets require chemical fluids to break down waste and control odour. Aqua Kem Blue is Thetford’s standard chemical fluid for the waste tank, while Aqua Rinse is added to the flush tank to keep the bowl clean. However, an important shift has occurred in UK camping: formaldehyde-free fluid is now required on many certified UK campsites, following guidance from The Caravan and Motorhome Club, because formaldehyde damages campsite septic systems. Always check the bottle before you buy.
Dry toilets sidestep the chemical question entirely but introduce their own disposal rules. In the UK, portable toilet waste from a chemical flush is legally classed as sewage — it must be deposited at a designated elsan point or CDP (cassette disposal point) found on campsites, and must never be tipped into household bins or hedgerows.
Ventilation: the hidden differentiator in dry toilets
If you opt for a dry separation toilet, ventilation is the feature that separates premium models from budget ones. A basic dry toilet relies solely on a sealed lid and cover material to trap odours. A fan-assisted model actively draws air down through the seat and vents it outside, which prevents smells from escaping into your tent or vehicle when the lid is open. This is the single feature that justifies the price premium of top-tier dry toilets.
The 4 best camping toilets in the UK for 2026
Thetford Porta Potti 365: best overall for families
If you want the closest thing to a real toilet that you can carry, the Thetford Porta Potti 365 is the model most UK campsite owners recommend, and for good reason. This is the full-size version of the legendary Porta Potti design, with a 21-litre waste tank and a 15-litre fresh-water tank according to manufacturer specs. Thetford states this capacity is sufficient for approximately 50 flushes per full waste tank — enough for a family of four to get through a long weekend without a dreaded middle-of-the-night empty.
The ergonomics are what set it apart. The piston pump flush delivers a strong swirl of water with each push, and the LED level indicator on the waste tank lights up in green and red so you know when it’s time to empty — no lifting the lid to check. A swivel spout makes pouring the waste tank out at the campsite elsan point genuinely easy, and the sturdy carry handle copes fine with the load.
The critical caveat is weight. The 365 weighs approximately 4.2 kg empty, but once you add around 15 kg of fresh water and a potential 21 kg of waste, the total full-load weight approaches 40 kg. That is a serious mass to lift into a vehicle boot — anyone without a boot trolley or a second pair of hands should plan their loading strategy carefully.
Owner consensus strongly backs the purchase. On Amazon UK, the 365 holds approximately 4.6 out of 5 stars from over 2,000 ratings, and forum threads on UKCampsite.co.uk frequently cite the model’s odour-seal reliability as their primary purchase driver. It typically retails for around £150–£175, with an RRP of approximately £175, though it is frequently discounted at Go Outdoors sale events.
Where to buy: Amazon UK, Go Outdoors.
Verdict: The gold standard of portable flush toilets — if you have the boot space and the muscle to handle a 40 kg full load.
Thetford Porta Potti 165: best value portable flush toilet
The Thetford Porta Potti 165 is the smaller sibling of the 365, offering the same trusted flush-and-seal architecture in a more compact and affordable package. According to Thetford’s official product page, it features a 12-litre waste tank and a 15-litre fresh-water tank, and measures 38.5 × 38.5 × 35 cm (H×W×D). It is lighter and shorter than the 365, making it far easier to manoeuvre in a cramped tent or vehicle.
The decisive trade-off is that 12-litre waste tank. At roughly half the capacity of the 365’s 21-litre tank, it means a family will likely face daily emptying runs to the elsan point rather than enjoying a whole weekend of autonomy. For solo campers, couples, or those who don’t mind a daily walk to the CDP, this is a perfectly acceptable compromise. The 165 also makes do with a simpler non-illuminated indicator, rather than the LED level display found on the 365.
Typically priced around £80–£110, it represents significant savings against the larger model while retaining the core Thetford seal quality that keeps odours at bay.
Where to buy: Amazon UK, Go Outdoors, Halfords.
Verdict: The smart choice for couples and solo campers who want Thetford reliability without the £175 price tag.
Trelino Evo S: best dry separation toilet for festivals
The Trelino Evo S takes a completely different approach to campsite sanitation. It is a urine-diverting dry separation toilet, meaning it uses no water and requires no chemical fluid. Instead, urine is channelled into a separate removable bottle with a capacity of approximately 1.5 L, while solid waste drops into a bag-lined solids container. The solids are covered with coconut fibre cover material, which absorbs moisture and neutralises odour through natural decomposition rather than chemical masking.
The specs are impressive for a dry toilet. It measures approximately 37 × 35 × 40 cm and weighs just 3.5 kg empty — a fraction of a full-load chemical toilet. Because it separates liquids and solids, there is no sewage to dispose of in the traditional sense. The liquids bottle can be emptied into a normal toilet, and the bagged solids can be composted (compostable bag options are available), though the bags themselves are sold separately.
This is where the Trelino shines for festival campers. Sentiment on Reddit’s r/UKcamping consistently praises dry toilets for festival use, specifically because festivals often lack an elsan point for chemical waste disposal. Without the need to hunt down a CDP, festival-goers can simply pack out their bagged waste.
The caveat is the ongoing cost of consumables: you will need to buy coconut fibre cover material and replacement bags (compostable or otherwise) as ongoing running costs, which chemical toilet owners avoid after the initial fluid purchase.
Typically priced around £220–£260, it is stocked by specialist UK outdoor retailers including Winfields Outdoors and Blackthorn Bushcraft.
Where to buy: Winfields Outdoors, Blackthorn Bushcraft.
Verdict: A clean, chemical-free solution that shines at festivals and off-grid sites without elsan access — provided you stay on top of the bag supply.
Separett Weekend 7010: best for fan-assisted odour control
The Separett Weekend 7010 is the premium dry toilet in this line-up, and its key differentiator is fan-assisted ventilation. Unlike the Trelino, which relies on its lid seal and cover material alone, the Separett actively draws air down through the seat and vents it via a 12 V or USB connection. This continuous negative pressure means odours are pulled out of the cabin before they can escape into your tent, van, or awning — a significant upgrade for enclosed spaces.
Like the Trelino, it is a urine-diverting design. The waste container has a capacity of approximately 15 L and fits standard bin liners, which simplifies the consumable situation compared to models requiring proprietary bags. It measures approximately 44 × 38 × 40 cm, making it slightly larger than the Trelino Evo S but still manageable for a portable setup.
The caveat is that the fan requires a power source. You need a 12 V supply or a USB power bank to run the ventilation, which means you must plan for battery capacity if you are camping off-grid. If your power runs out, the toilet reverts to being a basic dry toilet without the active odour extraction that justifies its premium price.
Typically priced around £280–£320 in the UK, it is available via Separett UK direct and Amazon UK.
Where to buy: Separett UK direct, Amazon UK.
Verdict: The most sophisticated dry toilet here — the fan ventilation makes it the clear pick for van conversions and enclosed tents, as long as you have the power to run it.
UK practical and regulatory notes
Understanding the legal and practical landscape of camping toilet disposal in the UK is just as important as choosing the right model. As mentioned above, portable toilet waste from a chemical system is legally classed as sewage. This means it must be deposited at a designated elsan point or CDP (cassette disposal point) provided by campsites. It must never be disposed of in household bins, public drains, or hedgerows. Doing so is not only antisocial but can result in penalties.
Furthermore, the chemical fluid you use matters. Aqua Kem Blue is Thetford’s standard waste-tank fluid, and Aqua Rinse is the flush-tank additive. However, The Caravan and Motorhome Club guidance now stipulates formaldehyde-free fluid on many certified UK campsites, because formaldehyde breaks down the bacteria that campsite septic systems rely on. If you buy a chemical toilet, check that your fluid is formaldehyde-free before you travel.
Frequently asked questions
What is an elsan point?
An elsan point, also known as a CDP (cassette disposal point), is a designated waste-disposal station found on UK campsites. It consists of a raised basin with a rinse tap where you empty your portable toilet’s sealed waste tank directly into the campsite’s sewage system. You must use these stations for chemical toilet waste, as it is legally classed as sewage.
How often do I need to empty a portable camping toilet?
It depends on the waste-tank capacity and the number of users. The Thetford Porta Potti 365, with its 21-litre tank, offers approximately 50 flushes before emptying. The smaller Porta Potti 165 has a 12-litre tank — roughly half the capacity — meaning a family will likely need to empty it daily. Dry toilets like the Trelino Evo S have a 1.5-litre liquids bottle that will need emptying daily, while the solids container lasts longer depending on usage.
Can I use a camping toilet at a festival?
Yes, but a dry separation toilet like the Trelino Evo S is usually the better choice. Festivals frequently lack elsan points for chemical waste disposal. Because dry toilets separate urine and solids, you can empty the liquids bottle in a normal toilet and pack out the bagged solids. Reddit’s r/UKcamping community frequently praises dry toilets for exactly this festival use case.
Do I need to buy chemical fluid for a camping toilet?
If you choose a flushable chemical toilet like the Thetford Porta Potti range, yes. You will need a waste-tank fluid like Aqua Kem Blue to break down waste and control odour, and a flush-tank additive like Aqua Rinse to keep the bowl clean. Many UK campsites now require formaldehyde-free fluid. Dry toilets like the Trelino Evo S and Separett Weekend 7010 require no chemical fluid at all.
How heavy is a full camping toilet?
A full chemical toilet is surprisingly heavy. The Thetford Porta Potti 365 weighs approximately 4.2 kg empty, but once you add around 15 kg of fresh water and up to 21 kg of waste, the total full-load weight approaches 40 kg. This is a critical consideration if you need to lift the toilet into a vehicle boot. Dry toilets are significantly lighter — the Trelino Evo S weighs just 3.5 kg empty and does not carry water.
