Seasonal Considerations for UK Van Life
Proper plumbing is the difference between a comfortable van life experience and one where you're constantly fetching water or struggling with condensation. This guide covers everything from basic water tanks to full pressurized systems.
Before buying anything, you need to answer:
- How many people will use the system?
- How long between water fills?
- What's your water consumption per person? (Average: 10-15 litres/day)
- Where will the tank go? (Floor area, weight distribution)
- Will you need heating for winter use?

- Capacity: 20-100 litres
- Pros: Lightweight, affordable, widely available
- Cons: Can develop odours over time
Stainless Steel Tanks (Premium)
- Cost: £80-200
- Capacity: 30-100 litres
- Pros: Durable, no odour, food-grade
- Cons: Heavy, expensive

- Capacity: 100-200 litres
- Pros: Massive capacity, cheap
- Cons: Not food-grade unless certified, heavy
Plumbing System Types
Basic Gravity Feed
Water flows from a raised tank through a tap. Simple, reliable, no power needed. Drawback: limited pressure (about 0.1 bar).
Pressurized System
A 12V diaphragm pump pressurizes the system like a house. Requires:
- 12V water pump (5-8L/min)
- Pressure switch or manual valve
- Hot water option (Webasto or 12V electric)
- Expansion vessel (for pressurized systems)
Cost: £80-200 for basic system
Shower System
Options include:
- Gardena shower bag: £5-10, solar-heated
- 12V electric shower: £40-80, fast hot water
- Manual pump shower: £20-40, no power needed
- Outdoor shower kit: £50-100, warm water tank
Winter Plumbing Tips
- Use antifreeze in freshwater tanks (food-grade propylene glycol)
- Wrap pipes with self-regulating heat tape
- Keep water moving (don't leave stagnant water overnight)
- Install a diesel heater specifically for the plumbing area
