A caravan bathroom is roughly the size of a phone booth, and yet it needs to handle showering, toilet, storage, and sometimes laundry duties for months or years on end. The good news: it works. The caveat: it works a lot better with the right products.
Your caravan’s bathroom came with the fixtures (toilet, shower, basin) but almost certainly didn’t come with the consumables, chemicals, cleaning products, and small accessories that make daily use comfortable and hygienic. This guide covers everything you need to stock your caravan bathroom properly, from toilet chemicals to the small products that make a disproportionate difference to daily comfort.
What Your Caravan Bathroom Already Has
Most new caravans with an ensuite include a cassette or swivel toilet, a shower (often combined with the toilet space), a small basin, a mirror, and basic storage. Some higher-end vans separate the shower from the toilet, and a few have a dedicated vanity area. What none of them come with is the consumable products you’ll need from day one: toilet chemicals, suitable cleaning products, toilet paper that’s septic safe, and the accessories that make a small bathroom functional.
If your van doesn’t have an ensuite (common in smaller caravans, camper trailers, and pop-tops), you’re not out of luck. There are portable and external solutions that work surprisingly well, covered in the final section of this guide.
Cleaning Products
Standard household cleaning products can damage caravan bathroom surfaces, seals, and particularly toilet cassettes. The plastics, rubbers, and sealants used in caravan bathrooms are different from household fixtures, and harsh chemicals (bleach, ammonia based cleaners, abrasive products) can cause cracking, discolouration, and seal failure over time.
Caravan specific cleaning products are formulated to clean effectively without damaging these materials. They’re also typically more concentrated (so you carry less), biodegradable (important for grey water disposal), and designed for the specific challenges of caravan bathrooms: mould in damp conditions, calcium buildup from hard water, and the rubber seals on cassette toilets.
Toilet Chemicals & Maintenance
If your caravan has a cassette toilet, you’ll need toilet chemicals. They serve two essential functions: breaking down waste and controlling odour. Without them, emptying the cassette becomes significantly more unpleasant, and the smell inside the van can become noticeable, particularly in warm weather.
The market has shifted significantly, with biodegradable and eco friendly formulations now performing as well as or better than traditional chemical heavy options. Given that you’ll be emptying waste at dump points, often in environmentally sensitive areas, choosing biodegradable chemicals is both responsible and increasingly expected at many campgrounds.
A solid starting point is Thetford Aqua Kem Green Concentrated (750ml). It’s one of the most widely used biodegradable cassette toilet treatments in Australia, available at most caravan and camping retailers, and a 750ml bottle goes a long way when used as directed.
Products That Make Life Easier
Caravan bathrooms are functional but rarely comfortable out of the box. A handful of inexpensive products and accessories can transform the experience from “I can cope with this” to “this actually works well.” The list below covers the products worth buying before you leave, organised by what problem they solve.
Towels
Standard bath towels take forever to dry in a small, often poorly ventilated bathroom and quickly develop that musty smell. The Sea to Summit Tek Towel is the go-to recommendation for caravanners. It dries fast, packs small, and doesn’t hold odour the way cotton towels do. Available in multiple sizes; most people find a large or extra large works well as a main towel.
Bathmats
Wet floors in a confined space are a slip hazard. The Stone Dry Bathmat and Tray Set from Kmart is a popular choice: the diatomite stone mat absorbs water almost instantly and dries quickly, the tray keeps water contained, and the whole thing takes up minimal floor space. At Kmart prices, it’s hard to argue against.
Suction Storage
Drilling into caravan walls is not the answer. Suction cup accessories are the practical solution for adding storage and organisation to a tiled or smooth walled bathroom without permanent fixtures. A few products worth having:
- Companion Suction Shelf (White) from Anaconda: a flat shelf that sticks to the wall for toiletries, soap, or a phone.
- Wanderer Suction Storage Shelf from BCF: similar concept, useful for keeping things off the basin or floor.
- Wanderer Suction Soap Holder: keeps soap dry and off surfaces where it tends to leave residue.
- Companion Suction Hook (White) from Anaconda: useful for hanging a towel, washcloth, or bag.
- Wanderer Suction Toothbrush Holder: keeps toothbrushes off the basin and out of the splash zone.
- Wanderer Suction Toilet Roll Holder: a simple fix for one of the most common complaints about caravan bathrooms (nowhere to put the toilet paper).
- Wanderer Suction Toilet Brush: holds itself to the wall rather than sitting on the floor taking up space.
Shower Screens and Splash Protection
In wet bath setups where the toilet and shower share a space, keeping water contained is a constant challenge. The Shower Guard from Tie Gear is a purpose built splash shield designed specifically for caravan wet bathrooms. It clips to the toilet to stop water getting where you don’t want it. A small thing that makes a real difference.
Travel Bottles
Carrying full size shampoo, conditioner, and body wash bottles is a waste of space and weight. The Go Travel Duo Squeezy Bottles are a compact solution: two squeezable bottles in a dual holder, colour coded so you don’t mix them up. They’re designed to be refilled from larger containers kept in your storage bay, which is the most practical approach for extended travel.
Buy your shampoo and body wash in bulk (2L refill bottles) and keep them in an external storage bay. Refill small travel bottles as needed. You save money, reduce plastic waste, and free up precious bathroom shelf space.
Bathroom Solutions Without An Ensuite
Not every caravan has an ensuite, and not every Big Lapper wants one. Smaller vans, camper trailers, and pop-tops often skip the bathroom entirely to maximise living space. That doesn’t mean going without. Portable toilets, external shower setups, and clever use of campground facilities can provide perfectly adequate bathroom access on the Big Lap. For some travellers, particularly those who stay primarily at caravan parks, the shared amenities block is actually preferred.
The SOG System
If your caravan has a cassette toilet and you’re tired of chemical costs, odour issues, or the environmental impact of traditional toilet chemicals, a SOG ventilation system is worth considering. It’s an electric fan system that fits to the cassette and extracts odours directly outside, potentially eliminating the need for toilet chemicals entirely. It’s not for everyone, but for those who find it suits their setup, it can simplify toilet management considerably.
- Never use household bleach or abrasive cleaners in your caravan bathroom. Caravan specific products protect seals and surfaces.
- Biodegradable toilet chemicals like Thetford Aqua Kem Green perform as well as traditional options and are better for the environment at dump points.
- A few inexpensive accessories (fast drying towels, suction storage, a stone bathmat, septic safe toilet paper) make a disproportionate difference to daily comfort.
- Suction cup fittings are the practical way to add storage and organisation without drilling into walls.
- No ensuite? Portable toilets and external showers provide practical solutions for smaller setups.
- Consider a SOG ventilation system if you want to reduce or eliminate toilet chemical use.
