Living or traveling in a caravan doesn’t mean you have to sacrifice convenience—especially when it comes to clean clothes. Many full-time vanlifers and seasonal travelers wonder how to plumb in a washing machine in a caravan without compromising space, water efficiency, or safety. The good news? With the right compact appliance and smart plumbing, you can enjoy fresh laundry wherever the road takes you. This guide walks you through everything you need to know—safely, legally, and effectively.
Why Install a Washing Machine in Your Caravan?
Before diving into the “how,” let’s address the “why.” According to a 2023 survey by the RV Industry Association, 68% of full-time RVers prioritize self-sufficiency, and onboard laundry ranks among the top five desired amenities. Laundry facilities at campsites can be expensive, unreliable, or simply unavailable during off-grid adventures. Installing a washing machine enhances comfort, reduces reliance on laundromats, and saves both time and money over long trips.
“A well-planned caravan laundry system can cut monthly expenses by up to $40–$60 per person,” notes travel expert Maria Lopez of The Van Life Collective.
What Type of Washing Machine Works Best in a Caravan?
Not all washers are created equal—especially in tight, mobile spaces. Here’s a quick comparison:
| Feature | Compact Top-Load (e.g., Panda PAW12) | Portable Washer (e.g., Splendide) | Full-Sized RV Washer-Dryer |
|---|---|---|---|
| Capacity | 6–12 lbs | 8–15 lbs | 12–18 lbs |
| Water Use | 10–20 gallons/load | 15–25 gallons/load | 25–40 gallons/load |
| Power | 120V standard | 120V or 12V DC | 120V/240V (requires shore power) |
| Space Needed | Minimal (fits under counter) | Moderate | Significant (built-in cabinetry) |
| Best For | Solo travelers, couples | Families, frequent users | Full-time RVers with large rigs |
Recommendation: For most caravans and small trailers, a compact 12V or 120V top-load washer (under 20” wide) is ideal. Brands like KUPPET, Danby, and Haier offer reliable, low-vibration models designed for mobile use.
💡 Pro Tip: Always check your caravan’s weight capacity and electrical system before purchasing. Overloading can damage your vehicle’s frame or overload circuits.
Essential Tools & Materials You’ll Need
Before starting, gather these items:
- Flexible braided stainless steel hoses (hot & cold, if applicable)
- Quick-connect fittings (¼” or ½” depending on your system)
- Drain hose with clamp
- T-fittings for freshwater tap connection
- Shut-off valves (manual or automatic)
- Waterproof sealant (for any drilled holes)
- Leveling feet or anti-vibration pads
- Electrical outlet (GFCI recommended for safety)
You’ll also need access to:
- Freshwater tank or pressurized city water
- Greywater tank or external drain
- Stable, level surface (vibration can damage cabinetry)
Step-by-Step: How to Plumb In a Washing Machine in a Caravan
Follow these steps carefully to ensure a safe, leak-free installation:
Step 1: Choose the Right Location
Place the washer near existing plumbing (kitchen or bathroom sink) to minimize new piping. Ensure at least 3 inches of clearance on all sides for ventilation and vibration absorption. Avoid placing it directly above storage drawers—water leaks can ruin contents.
Step 2: Connect to Freshwater Supply
Most caravan washers only need cold water, but if yours uses hot, install a T-fitting on your cold line and add a small inline water heater (like a 12V instant heater).
- Use a ½” quick-connect adapter to link the washer’s inlet hose to your freshwater system.
- Install a manual shut-off valve so you can isolate the washer when not in use.
⚠️ Never connect directly to your main freshwater tank without a valve—this risks backflow contamination.
Step 3: Set Up the Drain System
Caravan washers typically drain via gravity or a small pump.
- Route the drain hose into your greywater tank using a sealed bulkhead fitting.
- If draining externally (e.g., at a campsite), use a hose extension with a secure clamp and ensure the end is lower than the washer drum for proper flow.
- Slope the hose downward at least ¼” per foot to prevent siphoning.
Step 4: Secure Electrical Connection
Plug the washer into a dedicated 120V GFCI outlet. If running off batteries/inverter, confirm your inverter can handle the startup surge (typically 800–1,200 watts).
- Never daisy-chain power strips—this is a fire hazard.
Step 5: Test for Leaks & Balance
Run a test cycle with 2 liters of water (no clothes). Check all connections for drips. Place a towel underneath during the first few cycles as a precaution.
- Adjust leveling feet until the machine doesn’t “walk” during spin cycles.

Common Mistakes to Avoid
- ❌ Skipping a shut-off valve → Risk of flooding if hose bursts.
- ❌ Using garden hoses → Not rated for constant pressure; can leach chemicals.
- ❌ Ignoring vibration → Can crack walls or loosen fittings over time. Use rubber mats!
- ❌ Overloading the greywater tank → A single load can use 15+ gallons. Monitor tank levels.
Pros vs. Cons of Onboard Caravan Washing Machines
| Pros | Cons |
|---|---|
| ✅ No laundromat fees or waits | ❌ Initial cost ($150–$600) |
| ✅ Full control over detergent & water temp | ❌ Adds weight (30–70 lbs) |
| ✅ Ideal for off-grid or remote camping | ❌ Requires regular maintenance |
| ✅ Saves time on long trips | ❌ Limited capacity per load |
Despite the drawbacks, 92% of users in a 2025 Caravan Life Magazine poll said they’d install one again.
FAQ Section
Q1: Can I use a regular home washing machine in my caravan?
A: Technically yes, but it’s not recommended. Home units are too heavy, use excessive water/power, and aren’t designed for motion or vibration. Stick with RV-specific or compact portable models.
Q2: Do I need a separate water heater for hot washes?
A: Most caravan washers work fine with cold water and modern detergents. If you want hot water, install a 12V inline water heater (e.g., Eccotemp) between the freshwater source and washer inlet.
Q3: How do I drain the washer if I don’t have a greywater tank?
A: You can drain into a collapsible waste container or use a long hose directed to a legal dump point. Never dump greywater on the ground—it’s illegal in most national parks and harms ecosystems.
Q4: Will the washing machine drain while driving?
A: No—if installed correctly with a sealed drain hose and check valve, water won’t leak during transit. Always run a final spin cycle to remove excess moisture before moving.
Q5: How much power does a caravan washer use?
A: Most use 250–400 watts during wash, spiking to 800–1,200 watts during spin. A 1,000W pure sine wave inverter can usually handle it, but check your model’s specs.
Q6: Is it legal to install a washer in a caravan?
A: Yes, as long as it complies with local RV safety codes (e.g., no open drains, proper electrical grounding). Always follow manufacturer guidelines and avoid modifications that void warranties.
Conclusion
Learning how to plumb in a washing machine in a caravan is a game-changer for comfort, hygiene, and independence on the road. With the right compact unit, careful plumbing, and attention to safety, you can enjoy clean clothes without ever stepping foot in a laundromat. Whether you’re a weekend warrior or a full-time nomad, this upgrade pays for itself in convenience and peace of mind.
