ROAD SHOWER Road Shower 4S (4 gallons)

SKU: RS-4S04

Enjoy the comfort of hot, pressurized water during your vehicle-based adventures. Road Shower is like adding plumbing to your vehicle's rack. With the Road Shower, you can have instant and easy access to pressurized water wherever you go!

The Road Shower has many uses for adventurers and overlanders, beyond just showers. You can use it to assist with washing dishes, as a pressurized jet to rinse off dirty gear, to gently spray off pets, or for extra drinking water.

The folks at Road Shower have been hard at work improving their incredible roof rack-mounted showers and are now at version 4.0! The newest Road Shower 4 lineup comes in three models of varying sizes: 4S, 4, and 4L. Each Road Shower 4 model can be pressurized up to 65 psi, a huge improvement over the earlier showers. For reference, 65 psi is enough pressure to shoot water 45 ft! You'll probably want to tone it down a bit in order to shower comfortably outdoors, but it's a nice option to have if you need to blast mud off your gear!

Road Shower 4S Portable Camping Shower Features

There are no electrical parts to connect or propane to hook up. It is almost maintenance free and should last you many years. The tank absorbs sunlight to heat the water. Each Road Shower 4S has a dedicated, built in air chamber, so you can fill it up all the way, and then pressurize it without having to leave any space for air. You can fill it with water from a jug or hose and pump it up with a compressor or bike pump. Or you can simply fill & pressurize at the same time using your garden hose (note: the pressure achieved with this method will be equal to the pressure of the water line for your hose).

  • Instant easy access to hot pressurized water: no propane, pumps, or set up needed.
  • Black powder coated aluminum absorbs sunlight to heats the water inside.
  • LCD thermometer shows the temperature in F and C. Solar heated water can reach 100-115F!
