Shower on the Go: a modular water system for van life
Turn a basic faucet into a portable, refill‑ready shower that fits under any van roof rack.
A low‑cost, modular shower adds comfort without sacrificing storage.
What happened
I installed a compact pump, a flexible hose, and a quick‑connect showerhead onto a spare roof‑rack bracket. After a test run at a rest area, the system delivered a refreshing 5‑minute warm rinse using a 20‑liter jug.
Why it matters
Overnight stops often lack proper facilities, and a built‑in shower means you stay clean, save money on campground fees, and extend your range without hunting for a dump station.
How to think about it
Start with a standard 12‑V pump, mount a secure bracket, run the hose to a flexible showerhead, and integrate a water‑proof reservoir that can be refilled at any gas station. Test for leaks before the first road trip.
- Lightweight (<5 kg)
- Easy install in a weekend
- Uses standard 12 V power"
- Limited water capacity
- Needs manual refilling
- Pump can be noisy on low voltage
Secure all connections with hose clamps to avoid leaks while driving on rough roads.
FAQ
Can I run the pump off solar power?
Yes, a 20‑W solar panel with a small battery can handle a short shower if you pre‑charge the bank.
What hose diameter works best?
A ½‑inch flexible hose balances flow and storage space nicely.
How to keep the water warm?
Pre‑heat the water in a sealed container using a 12‑V immersion heater before pumping.
