Where Do You Shower? Hygiene When You Sleep in Your Car
Hygiene on the road is two things: a handful of accessories that live in one drawer, and picking stops that have facilities. Neither is complicated once someone tells you what to buy and what the rules are.
Three separate problems, and people conflate them:
- Washing — a paid network exists nearly everywhere, and it's cheaper than you think.
- The toilet — the one that needs planning, and in several countries the one that decides where you're allowed to sleep at all.
- Waste water — dishes, teeth, washing. This is the one that carries fines.
The one thing to buy first, before anything else on this page: a water container. Everything below assumes you're carrying your own water.
This is the question that stops people at the kitchen table. Not "will I be comfortable" — that one gets answered by a night in the driveway. Where do I wash? is the one that goes unanswered, and unanswered questions turn into never getting round to it.
So: the kit, the stops, the rules — with real numbers and no guessing.
0. Water: the first accessory to buy
A car carries water in a container rather than a tank, and how you carry it decides how easy everything else on this page is. Get this one right and washing, dishes and teeth all stop being a problem.
- 5–10 litres is the useful size. Ten litres weighs 10 kg — enough for two people to wash, brush teeth and do dishes for a couple of days, and still liftable with one hand.
- Rigid beats collapsible. A collapsible bag packs smaller and is worse at everything else: it won't stand up, it's awkward to pour from, and it fails at the seams eventually. A rigid jerry can with a tap you can turn on and leave running is what makes hand-washing work when you're alone.
- A second small bottle for drinking, kept separate. Once a container has had dishes rinsed near it, you'll stop wanting to drink from it.
- Refill where you empty. Campgrounds, aires and service points nearly always have a fresh water tap next to the disposal drain. Fill up every time you pass one, not when you run out.
Under a platform it lives in the drawer, upright and strapped, instead of rolling around the boot — which matters more than it sounds, because 10 kg loose in a boot is a projectile in a hard stop.
1. Washing
The realistic pattern for most people is a proper shower every two or three days and a wash at the sink in between. That isn't roughing it — it's what the network of paid facilities actually supports, and it's how most long-distance travellers end up doing it.
| Where | Cost | Notes |
|---|---|---|
| Holiday parks and campgrounds | Site fee | The default everywhere. An unpowered site is usually less than a takeaway meal, and it solves the toilet and the water at the same time. |
| Truck stops (US) | Around US$12, roughly $10–17 by chain and location | Open to anyone, not just drivers. Pilot Flying J and Love's rewards give a free shower credit per ~50 gallons of fuel — worth nothing to you if you drive an EV. |
| Public baths, sentō (Japan) | Tokyo: ¥600 adult | Capped by prefectural ordinance rather than set by the business. Tokyo's cap rose from ¥570 to ¥600 on 1 August 2026; children 6–11 ¥200, under 6 ¥100. Cheap, everywhere, and better than any campground shower. |
| Public pools and aquatic centres | Entry fee | Common across Australia and New Zealand. You pay for a swim and get a hot shower with it. |
| Gyms with multi-site membership | Monthly | Only worth it if you're travelling for weeks and the chain has branches on your route. Check the map before the trip, not during. |
| Beaches and surf clubs | Free | Cold, outdoors, in swimwear. Fine in summer, useless in April. |
Portable showers: buy one for what it's actually good at
A 12 V pump shower or a solar bag works well, and it's worth having. Just buy it for the right job.
What it's excellent at: rinsing sand and salt off after a swim, washing a dog's paws before they get on the bed, cleaning muddy boots and gear before it all goes back in the drawer. That's most weekends, and it saves your bedding.
What limits it as a full shower: not the hardware — where you're standing. Washing properly means several litres of soapy water on the ground and standing in the open, and most car parks, rest areas and council-managed land don't allow either. The places that do — campgrounds and motorhome service points — already have shower blocks and drains.
So: a rinse tool you'll use constantly, alongside a shower every few days somewhere with hot water. Both, not one instead of the other.
The in-between days
A litre of warm water and a flannel does more than people expect. What makes it workable is having it organised rather than improvised — a dedicated bag that lives in one drawer, not spread through three.
Hygiene kit — the full packing list
One bag, one drawer. Buy it once and it lives in the car — that's the difference between a routine you keep and one you abandon on night three.
- Rigid water container, 5–10 L, with a tap — the single most useful item here
- Microfibre towel — it dries; a cotton towel in a car does not
- Collapsible bowl or basin — for washing, for dishes, and for catching waste water instead of tipping it on the ground
- Biodegradable soap — one bottle that does body, hands and dishes
- Dry shampoo — so hair isn't what forces the timetable
- Wet wipes — the in-between-days item; pack them out, they are not flushable whatever the packet says
- Toothbrush, toothpaste, and a cup — the cup is the point, see below
- Hand sanitiser — kept in the door pocket, not the drawer, so it's reachable
- Dry bag for damp things — separate, and kept away from bedding
- Toilet paper in a zip bag — plus a second zip bag to pack out used paper where required
- Small bin bags — for everything above that has to leave with you
- Nail clippers, plasters, any medication — the things you only notice missing at 10pm
Optional, depending on where you're going:
- Portable toilet — for emergencies and for regions that require pack-out; note it does not make you self-contained in New Zealand
- WAG bags — required in some US desert and alpine areas rather than optional
- Trowel — only where burying is permitted, which is less often than people assume
- Portable shower — 12 V pump or solar bag, for sand, salt, dogs and gear
Brushing your teeth
Small thing, asked about constantly, and it has a wrong answer that most people default to.
Toothpaste spit is grey water. Spitting it on the ground beside the car in a car park is antisocial where it's tolerated and a waste-water offence where it isn't, and a storm drain is the worst option of all — those usually run straight to a river or the sea untreated.
- At a campground or service point: use the basin. Obvious, and it's most nights.
- Anywhere else: brush over your collapsible bowl or into a cup, and empty it at the next proper drain. One mouthful of water, so this costs nothing.
- In the wild, where burying is permitted: the accepted practice is to use very little toothpaste, spray the spit widely rather than in one spot, and stay well away from water. Best avoided altogether if a drain is within an hour's drive.
- Never into a storm drain, a stream, or a lake.
Same logic applies to the water you wash your face in. It's small enough that people don't think of it as waste, which is exactly why it ends up in the wrong place.
2. The toilet — country by country
Daytime is a solved problem: service stations, supermarkets, public toilets, cafés. It's the night that needs a plan, and the plan is mostly about where you park: a campground or a rest area with facilities means you walk twenty metres instead of driving twenty minutes.
Where the rules differ is whether a toilet on board is required — and that's a legality question, not a comfort one.
| Country | Is a toilet on board required? | Where to empty |
|---|---|---|
| New Zealand | Yes, and it must be fixed. Freedom camping on council-managed land requires a certified self-contained vehicle with a toilet permanently secured to the floor and usable with the beds set up. A car platform can never qualify — see the box below. | Dump stations at holiday parks, DOC campsites and many town facilities. |
| Australia | No national rule, but many councils require self-containment for free camping and each defines it differently. Read the signage where you are — a beach that's fine in one shire is a fine in the next. | Dump points at most campgrounds, usually free or a small fee. |
| USA | No certification system. On BLM and dispersed land the rule is about disposal: bury 15–20 cm (6–8 in) deep, at least 60 m (200 ft) from water, trails and campsites. Desert and alpine areas require packing waste out in a WAG bag rather than burying it — check the field office for the specific area. | Dump stations at RV parks, many campgrounds and some rest areas. |
| France, Germany, Italy, Spain | No, but overnight parking is concentrated on aires / Stellplätze / aree di sosta, most of which have a service point. That's where the infrastructure is, so that's where you end up. | Chemical disposal point at the service area. Typically free to about €5, and usually with a fresh water tap alongside. |
| UK | No, but there's very little legal wild camping in England and Wales without the landowner's permission, so you'll be on campsites anyway. | Chemical disposal point (often signed "Elsan") at campsites. |
| Japan | No. Roadside stations and 24-hour convenience stores are the practical network, and they're dense. | Campgrounds and RV parks. Far fewer public dump points than in Europe or Australasia. |
Under the Self-contained Motor Vehicles Legislation Act 2023, certification requires a fixed toilet — permanently secured to the floor, and usable while the beds are set up. Portable toilets no longer qualify, and only green warrant cards are valid evidence; the old blue cards have been phased out.
This is a rule about plumbing, and it applies to every car-based setup in the country — no car can be certified, whoever built the bed. So freedom camping on council-managed land isn't the plan in New Zealand.
The plan that does work: DOC campsites, holiday parks, and any area a council designates for non-self-contained vehicles. There are hundreds, most cost very little, and they all have toilets, showers and a tap to refill from. Details: MBIE — freedom camping changes and DOC campsites.
The portable toilet: worth having
Legal to own everywhere and genuinely useful at 3am, in bad weather, and with kids who can't wait. It's the accessory most people add after their first trip. One thing to know: it doesn't count towards self-containment in New Zealand, so it's for comfort rather than for unlocking places to park. Empty it at a proper disposal point — never into a public toilet's floor drain, a hedge, a storm drain or a rubbish bin. The cassette goes into a chemical disposal point and nowhere else.
3. Dump points and waste water — the part that gets fined
Washing-up water, shower water and toothpaste spit all count as grey water: soap, grease, food particles. It's the least glamorous item on this page and the one most likely to cost you money.
The rules, wherever you are
- Never into a waterway, a drain or a storm drain. Storm drains usually run straight to a river or the sea untreated. In Australia this is illegal in many places, and tipping grey water onto the road while driving is prohibited.
- Never near a water source you'd drink from, even with biodegradable soap. "Biodegradable" describes what happens in soil over time, not what happens in a stream tonight.
- Grey and black go to different places. Grey water into the drive-over drain; toilet cassette into the chemical disposal point. Don't improvise the order at a busy aire.
- Spain is the strict end of Europe. Emptying waste water outside a designated point attracts penalties starting in the low hundreds of euros, and considerably more in protected coastal and natural areas.
Where the dump points are
| Region | What to look for |
|---|---|
| Australia & New Zealand | "Dump point" or "dump station" — at most campgrounds and holiday parks, at many town facilities, usually free or a small fee. Widely mapped. |
| France | "Aire de service" — often at aires, but also at motorway services, supermarket car parks and town car parks. Drive-over grey drain, chemical disposal point, fresh water tap. |
| Germany & Austria | "Ver- und Entsorgungsstation" at Stellplätze. Same three services, usually coin-operated. |
| UK | Chemical disposal point at campsites, commonly signed "Elsan". |
| USA | "Dump station" at RV parks, many state and national park campgrounds, and some interstate rest areas. |
The practical fix is upstream: generate less of it. Wipe plates with a paper towel before washing, cook things that don't leave grease, and use one collapsible bowl rather than tipping water on the ground. One bowl of washing-up water travels fine to the next proper sink.
Where it all lives
A wash kit is small. What makes it work is that every piece has a fixed home, so nothing is being hunted for in the dark or left where it gets wet.
| Item | Where it goes |
|---|---|
| Water container | In the drawer, upright and strapped. Reachable from the tailgate without moving anything else, and not rolling around at 100 km/h. |
| Wash bag | One drawer, one bag. The reason people abandon a routine on the road is that the toothbrush is in a different place every night. |
| Damp things | Dry bag, in the drawer under the bed — deliberately away from bedding. Wet bedding stops insulating, which turns a mild night into a cold one. |
| Getting changed | On the bed, lying down, with the windows covered. Blackout covers are what make this private rather than theoretical — ours are cut for the Model Y; for other cars, buy to fit. |
| Dishes and the stove | Their own module, separate from the wash kit. BOX keeps cooking gear out of the same drawer as your towel. |
And the part that matters most on a bad evening: when the bed is already made and nothing is unpacked on the ground, driving twenty minutes to a campground with hot showers costs you the drive and nothing else. That's what makes "stay somewhere with facilities" the easy default instead of a compromise.
Facilities and legality are the same question. Where are you actually allowed to stop?
New Zealand's fixed-toilet rule is the sharpest example, but every country ties overnight stays to whether the place is serviced. It's national law, then state, then council — and it changes between neighbouring towns.

Where do you shower when you sleep in your car?
Campgrounds and holiday parks are the default. Beyond that: truck stops in the US at roughly $12 a shower, public baths in Japan capped at ¥600 for an adult in Tokyo, public pools and aquatic centres across Australia and New Zealand, and gyms with multi-site membership if you're travelling for weeks. Most people shower properly every two or three days and wash at a sink in between.
Are portable car showers worth buying?
Yes, for rinsing — sand and salt after a swim, a dog's paws before they get on the bed, muddy boots and gear. You'll use it most weekends. As a full shower it's limited by where you're standing rather than by the hardware: soapy water on the ground and washing in the open aren't allowed in most car parks and rest areas, and the places that do allow it already have shower blocks. Carry one and shower properly every few days.
What water container should I get?
A rigid 5–10 litre jerry can with a tap is the useful size — enough for two people for a couple of days, still liftable, and it stands up so you can run water hands-free. Refill at campgrounds and service points every time you pass one.
Do you need a toilet in the car?
It depends where. In New Zealand, freedom camping on council-managed land requires a certified self-contained vehicle with a fixed toilet, so a car with a platform must use campsites, holiday parks or designated non-self-contained areas. In Australia many councils require self-containment for free camping and define it differently. In the US the rule is about disposal rather than equipment, and some desert and alpine areas require you to pack waste out. In Europe, aires and Stellplätze mean the infrastructure comes to you.
Where do you brush your teeth?
At a campground or service point, use the basin. Anywhere else, brush over a collapsible bowl or cup and empty it at the next proper drain. Toothpaste spit is grey water — never into a storm drain, a stream or a lake.
Where do you empty washing-up water?
At a dump point. Most campgrounds in Australia and New Zealand have one, aires in France and Stellplätze in Germany have a drive-over grey drain, UK campsites have a chemical disposal point, and US RV parks and many campgrounds have dump stations. Never into a waterway, a storm drain, or onto the road while driving. In Spain penalties start in the low hundreds of euros and rise sharply in protected areas.
Is car camping unhygienic?
It's as hygienic as your routine and your choice of stops. Three things make it easy: a container of water, a wash kit with a fixed home in the drawer, and a habit of picking sites with facilities. People who improvise it are the ones who find it hard.
Start with the drawer everything lives in
A bed that's already made, water and wash kit in a drawer that stops where you put it on a slope — so moving to a site with hot showers is a two-minute decision instead of a repack.
