The right RV toilet depends on your caravan’s layout and how you travel. Portable units suit caravans without a fixed bathroom or travellers who camp away from dump points, while permanently installed and macerator pump toilets suit caravans with existing plumbing and a dedicated bathroom space. Each type has different maintenance needs and capacity limits worth considering before you buy.
Choosing the right RV toilets can make a noticeable difference to comfort and convenience on the road. It’s one of those decisions that seems minor until you’re parked somewhere without facilities and realise your setup doesn’t quite work for the way you travel. The best option depends on your caravan’s layout, how often you’re away from powered sites or dump points, and how much space you actually have to work with.
At Boat Hut, we stock caravan toilets from trusted brands, with a range of options to suit different budgets and travel styles. This guide walks through the main types available, how to decide between a portable and an installed unit, and what’s involved in keeping a caravan toilet clean and functional over time.
What Types of Caravan Toilets Are Available?
There are three main categories of caravan toilet on the market, and each suits a different kind of setup.
Portable Caravan Toilets
Portable caravan toilets, sometimes called Porta Pottis, are self-contained units with a freshwater flush tank on top and a waste tank on the bottom. They don’t require any plumbing connection, which makes them straightforward to position wherever there’s space and easy to move if your needs change.
Most portable caravan toilets weigh under 5kg when empty, so one person can generally carry and empty the unit without assistance. This makes them a practical choice for smaller caravans, camper trailers, or anyone who prefers not to commit to a fixed bathroom fitout.
Permanently Installed Caravan Toilets
Permanently installed caravan toilets are fixed units that connect to your caravan’s existing water supply and an external waste cassette. They function much closer to a household toilet, both in appearance and day-to-day use.
These units are better suited to caravans that already have a dedicated bathroom space and the plumbing in place to support a fixed fixture. If your caravan was built with a bathroom in mind, an installed toilet is usually the more natural fit.
Macerator Pump Toilets
Macerator pump toilets use a separate toilet bowl and waste tank, with waste moved through the system via a macerator pump. They’re commonly available in 12-volt or 24-volt versions and share similarities with the toilet systems used on boats.
Some models include quiet flush options, which can be worth considering if noise is a concern in a shared caravan space. Because they rely on a pump system, macerator toilets tend to suit caravans with reliable power access.
Portable vs Installed: Which One Suits Your Setup?
Deciding between a portable and installed toilet comes down to your caravan’s existing layout and how you actually use it.
A portable toilet can be a good option if:
- Your caravan doesn’t have a dedicated bathroom space
- You regularly camp away from dump points or powered sites
- You want the flexibility to store the toilet when it isn’t needed
Larger-capacity portable models are particularly useful for longer stays, where emptying the tank frequently isn’t practical or convenient.
An installed toilet makes more sense when your caravan already has a bathroom fitted out for it. It offers a permanent fixture that functions more like the one you use at home, which some travellers find more comfortable for extended trips. Installation is generally straightforward, whether you handle it yourself or have a professional fit it for you.
Neither option is inherently better than the other. The right choice depends on your caravan’s existing setup and your travel habits, not on which toilet has the most features.
How Do You Maintain and Clean a Caravan Toilet?
A caravan toilet is easy to maintain with the right routine. Regular cleaning, suitable toilet chemicals, and a bit of care with the seals and valves will keep most units in good working order for years.
The most important consideration is using the right products for the toilet. A suitable toilet chemical in the waste tank helps break down waste and control odours, while a freshwater treatment helps keep a separated flush tank clean between uses. Using the wrong products, or skipping them altogether, can shorten the life of seals and valves over time.
After each trip, it’s worth emptying and rinsing the waste tank and flushing the freshwater tank to remove any residue. If the toilet is going into storage for a while, leaving the tanks open to air can help prevent unpleasant smells building up inside the unit.
A few maintenance habits worth building into your routine:
- Rinse the waste tank thoroughly after each emptying
- Use a dedicated RV or marine toilet chemical, not general household cleaners
- Check seals periodically for wear, particularly on portable units that get moved often
- Air out tanks before long periods of storage
These steps are simple, but skipping them is one of the more common reasons caravan toilets develop odour issues or valve problems earlier than expected.
What Should You Consider Before Buying?
Before choosing a caravan toilet, it helps to think through a few practical factors rather than focusing only on price.
Space and layout. Measure the area where the toilet will sit, particularly for installed units where plumbing connections need to line up with existing fittings.
Tank capacity. If you travel for extended periods without access to a dump point, a larger waste tank reduces how often you need to empty it.
Power availability. Macerator pump toilets need a reliable 12-volt or 24-volt power source, so check your caravan’s electrical setup can support one before buying.
Ease of use for your travel group. Portable units are generally easier for one person to manage, which matters if you’re travelling solo or with limited mobility in the group.
Choose a portable toilet if your caravan lacks a bathroom or you value flexibility over permanence. Choose an installed or macerator toilet if your caravan already has the plumbing and you prefer a setup that feels more like home.

Frequently Asked Questions
What’s the difference between a portable and an installed caravan toilet?
A portable caravan toilet is a self-contained unit with no plumbing connection, making it easy to move or store. An installed toilet connects to your caravan’s existing water supply and an external waste cassette, functioning more like a household toilet.
How often should I empty a portable caravan toilet?
This depends on the tank capacity and how many people are using it, but most portable units need emptying every few days during regular use. Larger-capacity models extend the time between emptying, which suits longer stays away from dump points.
Do macerator pump toilets need a lot of power?
Macerator toilets run on 12-volt or 24-volt power, so they do draw from your caravan’s electrical system each time they’re flushed. It’s worth checking your power setup can handle this before choosing a macerator model.
What chemicals should I use in a caravan toilet?
Use a toilet chemical designed for RV or marine use in the waste tank to help break down waste and control odour. A separate freshwater tank treatment can help keep the flush tank clean between uses.
Can I install a caravan toilet myself?
Installing a fixed caravan toilet is generally straightforward if your caravan already has the plumbing in place, and many travellers do it themselves. If you’re unsure about the connections, having it professionally installed avoids the risk of leaks or faulty fittings.
Choosing the right RV toilets comes down to matching the unit to your caravan’s layout and your own travel habits, rather than picking the option with the most features. Whether you need a portable unit for flexibility or an installed system for a caravan with a dedicated bathroom, taking the time to consider tank capacity, power needs, and maintenance requirements will help you make a choice that suits your trips for years to come.
