 With the Road Shower 4S you can have pressurized water wherever you go. If sunny, it can heat the water while you drive or are parked and can be ready to give you a high pressure hot shower. Hot or cold, the Road Shower has many uses: from the camp hose for dishes, a pressurized jet to rinse off dirty gear, a gentle spray for the pets, or for extra drinking water. There are no electrical parts to connect or propane to hook up. It is almost maintenance free and should last you many years. The water is there when you need it.

On cloudy days it is possible to add hot water from your sink or camp stove, or use a small instant hot water heater under accessories, and still enjoy a hot shower.

If you are going to mount to the side of a rack using the side T-slot, we recommend at least 3 mounting brackets. Since the Road Showers come with 2 brackets you will need to purchase an extra set.  If you purchase them at the time you buy your Road Shower, use the coupon code 12off to get $12 off the cost.

Model Comparison Chart

Here is a video of the Road Shower 4S.

Road Shower 4S model features and comes with these parts except those listed as optional:

  • Powder coated aluminum that absorbs sunlight and heats the water inside.
  • Holds 4 gallons of water…enough for 2 showers.
  • 3 hose clips and 2 velcro straps to hold the hose while driving.
  • Sleek design and high end components look great on your vehicle.
  • On/off valve at elbow so you can easily remove the hose or attach a longer hose while pressurized.
  • Shrader style air valve so you can pressurize on the go.
  • There is a locking loop to lock your unit with a cable style bike lock to your rack.
  • LCD thermometer shows the temperature in F and C.
  • 2 Beefy universal mounting brackets mount to most racks including 4 short bolts and 4 long bolts and 4 nylock nuts.
  • Female to female hose connector for filling and pressurizing from your garden hose
  • Built in 1 gallon air space. So after you fill it there is still room for pressurized air.
  • Can take up to 65 PSI.   There is some air space built in even if you fill it all the way up. Full tanks may require 1 extra re-pressurization depending if your car was level or not when you filled it up. It helps to fill just shy of full to drain the tank with 1 pumping.   This gives about 3-9 minutes of pressurized water depending on if you are using it full blast or dialing it back  with the black handle to conserve water.
  • The optional low flow flex neck shower head also helps regulate and reduce excess flow and makes for  a great shower.  If you get that, I recommend getting the optional extra on/off elbow.  You can install it on the other end of your Road Shower and use the quick connect on the shower head to attach when needed and remove when leaving the beach. Also, having 2 outlets allows you to use the downhill end to drain the tank completely without moving your vehicle. 

For one year from date of purchase, if defective in material or workmanship  —  Road Shower will  troubleshoot and repair with your assistance,  or replace or refund if not reparable, free of charge.  See our full warranty policy here.
