If you’re living in or frequently using a static caravan, doing laundry off-site can quickly become a chore—hauling clothes, paying for laundromats, or relying on hand-washing just isn’t sustainable. It’s no wonder many caravan owners ask: “Can you plumb a washing machine into a static caravan?” The good news? Yes, you absolutely can—but it requires careful planning, the right setup, and awareness of site rules and local regulations. In this guide, we’ll walk you through everything you need to know to install a washing machine safely and efficiently in your static caravan.
What Is a Static Caravan (and Why Does It Matter)?
A static caravan is a prefabricated mobile home permanently sited on a holiday park or residential park. Unlike touring caravans, static caravans are designed for long-term or year-round use and often come with more robust electrical and plumbing systems.
However, not all static caravans are plumbed for appliances like washing machines. Many are built for seasonal use and may lack proper drainage, water pressure, or waste management for high-volume appliances. That’s why understanding your caravan’s infrastructure—and the park’s rules—is the first critical step.
💡 According to the National Caravan Council (NCC) in the UK, over 60% of modern static caravans on licensed residential parks now include provisions for white goods—but older or holiday-only models often don’t.
Is It Legal and Allowed by Your Park?
Before you buy a washer or call a plumber, check your site agreement. Most caravan parks have specific rules about modifications, especially those involving plumbing or drainage.
- Residential parks (for year-round living) are more likely to allow permanent appliance installations.
- Holiday parks may prohibit permanent plumbing to avoid greywater contamination or strain on shared systems.
Always get written permission from park management. Unauthorized modifications can void your insurance or lease.
Key Requirements for Plumbing a Washing Machine in a Static Caravan
To successfully plumb in a washing machine, you’ll need three core connections:
- Cold water supply (most caravan washers only use cold fill)
- Waste water (greywater) drainage
- Electrical power (typically 13A UK socket or 120V US outlet)
Let’s break these down:
1. Water Supply
Most static caravans have a mains cold water feed. You’ll need to tap into this using a tee connector and a dedicated isolation valve. Always use flexible braided hoses rated for appliance use—standard garden hoses aren’t safe.
✅ Pro Tip: Install a pressure-reducing valve if your site’s water pressure exceeds 3 bar (43 psi). High pressure can damage caravan pipework.
2. Drainage (The Trickiest Part)
This is where most installations fail. Washing machines discharge 50–70 liters per cycle. Your caravan’s existing sink waste pipe (usually 32–40mm) is not sufficient for this volume.
You have two safe options:
- Connect to the caravan’s black/greywater tank (if it has one and is regularly emptied)
- Plumb directly into the site’s drainage system (only with park approval)
Never drain greywater onto the ground—it violates environmental regulations in most states and the UK.
🌍 According to the EPA, improper greywater disposal can contaminate soil and groundwater. Always follow local wastewater codes.
For more on greywater systems, see Wikipedia’s overview on greywater.
3. Electrical Setup
Washing machines draw 1,800–2,200 watts. Ensure your caravan’s circuit can handle it:
- Use a dedicated 13A radial circuit (UK) or 20A circuit (US)
- Install a GFCI/RCD-protected outlet near the machine
- Never use extension cords
Step-by-Step Installation Guide
Follow these steps for a safe, compliant install:
- Get park approval in writing.
- Choose a compact, low-water machine (e.g., 6–7kg capacity, cold-fill only).
- Turn off main water and electricity before working.
- Install tee connector on cold water line + isolation valve.
- Run waste hose to approved drainage (use 40mm pipe with slight downward slope).
- Mount machine on anti-vibration pads to reduce noise and movement.
- Test for leaks—run a rinse cycle and check all connections.
- Label isolation valves for emergency shut-off.
⚠️ Warning: Never connect the waste hose to a sink trap without an air gap—it risks siphoning dirty water back into your caravan.
Best Washing Machines for Static Caravans (2025 Picks)
Not all machines are caravan-friendly. Look for:
- Compact depth (<55cm)
- Low water consumption (<50L/cycle)
- Cold-fill only (saves energy)
- 120V compatibility (for US sites)
| Model | Capacity | Water Use | Depth | Ideal For |
|---|---|---|---|---|
| Beko WMF621021 | 6kg | 48L | 52cm | UK parks |
| LG WM1388HW | 1.5 cu ft | 12 gal | 24″ | US RV parks |
| Siemens WT45HVS9 | 7kg | 45L | 53cm | Year-round use |
Pros and Cons of Installing a Washing Machine
| Pros | Cons |
|---|---|
| ✅ Saves time & laundromat costs | ❌ Requires park approval |
| ✅ More convenient for families | ❌ Adds weight & vibration stress |
| ✅ Increases caravan usability | ❌ Risk of leaks if poorly installed |
| ✅ Better hygiene vs. public machines | ❌ Ongoing water/electricity costs |
Common Mistakes to Avoid
- Using sink waste pipes for drainage → causes backups and overflows
- Ignoring water pressure → leads to burst hoses or leaks
- Skipping RCD protection → fire/electrocution risk
- Installing without ventilation → mold and condensation
FAQ Section
Q1: Can I use a portable washing machine instead?
A: Yes! Portable (12V or compact electric) washers are a great low-impact alternative. They use less water and don’t require permanent plumbing—but they hold only 2–4kg of laundry.
Q2: Do I need planning permission?
A: No—plumbing a washing machine is considered a minor internal modification. However, park rules still apply, and unauthorized changes can result in fines or eviction.
Q3: How much does installation cost?
A: DIY: $100–$200 for parts. Professional: $300–$600, depending on drainage complexity. Always get quotes from caravan-certified plumbers.
Q4: Can I install a washer in a holiday-only caravan?
A: Technically yes—but many holiday parks ban permanent appliances. Check your license agreement. For occasional use, a portable unit is safer and more compliant.
Q5: What if my caravan has no greywater tank?
A: You’ll need to connect to the site’s main drainage—but only with written permission. Never discharge greywater into soakaways or gardens without approved filtration.
Q6: Will a washing machine damage my caravan’s structure?
A: Only if poorly secured. Use anti-vibration pads, level the machine properly, and ensure the floor can support 60–80kg when full. Reinforce subfloors if needed.
Conclusion
So, can you plumb a washing machine into a static caravan? Absolutely—if you follow safety protocols, respect park regulations, and use the right equipment. Doing so transforms your caravan from a weekend escape into a truly functional, comfortable home—whether you’re retired, remote-working, or raising a family on-site.
Don’t let laundry logistics hold you back. With the right prep, your static caravan can offer all the comforts of a traditional home—right down to fresh, clean clothes.
