Staying hydrated is one of the simplest yet most important aspects of van life health. In a van, your water supply is limited, so you need to be intentional about hydration — you can't just open the tap when you're thirsty.
This guide covers practical hydration strategies for UK van lifers.
Daily Water Needs
The NHS recommends 6–8 glasses (1.2 litres) of water per day for adults. In a van, plan for:
- Drinking: 2 litres per day (minimum)
- Cooking: 0.5 litres per day
- Cleaning: 1–2 litres per day
- Total: 3–4 litres per day
Water Storage
Water tank
A 20–40L water tank (like the Shurflo Fresh Water Tank, £30–£50) is the most reliable solution. Mount it securely and include a water pump for easy access.
Collapsible water containers
Hydra Rhino or Aquapac collapsible containers (£15–£25) are space-efficient and portable.
The water tap method
Keep multiple 1.5L bottles in the fridge, drinking one per half day. Simple, zero cost, and easy to stock up on at supermarkets.
Water Filtration
Brita filter
A Brita jug or bottle filter (£10–£20) improves tap water taste and removes impurities.
Grunfeld water filter
A simple gravity water filter (£15–£25) is excellent for rural UK water sources.
LifeStraw
A single-use personal water filter (£5–£10) for emergency drinking water.
Electrolyte Balance
In summer or during exercise, you lose electrolytes through sweat. Add:
- Electrolyte tablets — Mio, Nuun (£3–£5 for 10 tablets)
- Coconut water — High in potassium
- Bananas and nuts — Natural electrolyte sources
Final Verdict
The simplest hydration strategy: carry 2L of water in the fridge + fill a reusable bottle daily. For extended off-grid stays, invest in a water tank and filter. Keep electrolyte tablets handy for summer.

Pro Tips from Real Van Lifers
- Always keep a spare key fob for your van's doors and locks
- Invest in a good quality multi-tool — it's the most used item in any van
- Label everything with masking tape during build, then permanent markers later
- Keep a small first aid kit accessible, not buried in storage
- Have a backup power source (portable battery) for phone navigation
- Keep wet wipes and a small towel in the glove box for quick cleanups
- Use door wedge chocks on uneven ground for extra stability
- Keep a small dictionary of local Welsh/Cornish words if traveling to those regions
Seasonal Considerations for UK Van Life
Spring (March-May): Great time for wild camping as days get longer. Still possible to get rain — keep waterproofing gear handy.
Summer (June-August): Peak season — campsites fill fast. Can get very warm in vans — invest in roof vents and fans. Late sunset (10pm) means more light for exploring.
Autumn (September-November): Fewer crowds, great for solitary camping. Leaves fall making single-track roads slippery.
Winter (December-February): Shortest days (sun sets by 4pm in December). Condensation management is critical — vent windows slightly. Keep de-icer in the glove box.
