Solar shower for €30 yourself build

March 2026 · 8 min. reading time · from your Tussy

After two weeks on the Atlantic coast without a campsite, it was clear: I want a warm shower without paying €8 for one Campsite shower. The solution has been hanging on my tailgate ever since - and costs less than two pizzas with a sea view.

🛒 Shopping list (approx. 30 €):
  • 20 m garden hose, black (the trick!) - approx. 12 €
  • Shower head with stop button — approx. 6 €
  • 2 hose couplings + end plugs - approx. 5 €
  • Suction cup hooks & cable ties — approx. 4 €
  • Valve adapter for filling - approx. 3 €

The principle

A black hose on the roof is a solar collector: 20 meters hold a good 6 liters of water, and after two hours of sun they are between 35 and 45 degrees warm. No tank, no pump, no electricity — physics does the work.

Construction in 6 steps

  1. Lay the hose into a flat spiral and fix it with cable ties.
  2. Clamp the spiral on the roof or under the rear window - the main thing is sunshine.
  3. Close the lower end with a coupling + end plug.
  4. The upper end is fitted with the valve adapter - this is where you fill in water.
  5. Screw on the shower head, hang the end of the hose over the tailgate.
  6. Fill, wait 2 hours, shower. Done!

My learnings after a summer

First: the water is really hot at midday - test it first, then put it under The stop button on the shower head is worth its weight in gold, 6 liters are easily enough for hair + everything. Third: In Portugal, a neighbor invited me to dinner for the construction. The best test: Start small in the vehicle, work on the road for a few days and honestly observe how you feel with it plus several months of the year traveling.
