Return Authorization Form


1) How do I check the water level?

Answer: By the way, you can check the water level using the clear poly hose. Just open the cap and hold the hose nozzle above the top of the shower, and pull the trigger. The water inside the shower will fill the clear hose and show you the water level. Or check with your finger in the top or a stick. If you have an extra outlet installed on your Road Shower, use the uphill one first. As it starts to spray air, switch to the downhill outlet, knowing you have only 1-2 gallons left at that point.

2) How hot will it get?

Road Shower uses the renewable energy of the sun. The sun heats the black surface on the outside which heats the water on the inside. The water temperature rises 12-20 degrees per hour on a warm sunny day. If your water starts at 60 degrees, it should be 90+ degrees in about 2 hours. On a hot sunny day the water can get to 110 F, on a really hot day it might scald you, so be careful. Just feel the tank with your hand. The water will be the temperature of the tank. For added safety, spray some water on your hand to see if it is too hot. Check out our accessory page for where to get a little stick on thermometer. Allow about 10 seconds to drain the hose and get the heated water from the tank. If the water is too hot, wait until it cools or drain some and add a gallon of cool water. It heats up while you are driving down the highway, 4 wheeling, or parked somewhere in the sun. The Road Shower does not heat water as well if the outside temperature is below 70 degrees and/or the sun is low in the sky, or during cloudy days. However, if the water is about 70 degrees in the tank, you can heat 1 gallon of water on a camp stove, add it to 3 gallons of water in the tank, and the water will be about 100 degrees.

We are working on a neoprene cover with a solar collector for those cooler climates. You can use a portable instant hot water heater as well. See it here.

3) Can you ship to Alaska and Hawaii?

Yes via UPS, but you can save money from our Ebay store. There you can choose USPS and get a much better shipping rate.

4) Can you ship to Canada or Europe?

For countries around the world where we have no dealers, we can ship it to you from our ebay store. We do not ship to Canada since we have a dealer there. We do not ship directly from our online store to other countries.

5) Can Road Shower be mounted vertically?

Yes...just make sure it is secure. Fill cap would go towards the top.

Also, due to the flat nature of the bottom, you can take it off your car and put it on a flat table or other flat surface.

6) My Road Shower got a little loose on a rough road. What can I do about it?

It will come loose if it is not tight enough or the mounting brackets are not for your application. Tigthen them really tight. You can't hurt the shower. It is reinforced along the slot. What will damage the slot is if the bolt is loose and bangs around.

Answer: From the current owner's manual.

We recommend using a lube like WD-40 on the nuts and bolts prior to the first install. They are stainless steel and on rare occasions can cold weld or seize...especially if you turn them fast.

Mounting: Use a 1/2” wrench or a socket wrench to tighten the nuts.  They should be very tight. You can tighten them as tight as they go. Once both brackets are secure, push and pull on the Road Shower sideways , and see if it slips along the bar. If it slips, tighten more. If you reuse nylock nuts, they lose their ability to stay locked. Be sure to use your lock washers if you reuse the nylock nuts.

You can tighten the mounting straps to the point of bending, all the way down if you need to like this picture. Even better is to mount it inside your towers, so it cannot slide off.

Be sure to mount the Road Shower securely and tightly. Check  and tighten after driving on rough roads, as it could loosen.
Failure to do so, could result in the Road Shower flying off your vehicle in a quick stop or an accident, causing injury to other people or vehicles. It could also cause damage to your own vehicle. Make sure nozzle and hose are secured to the hose mount prior to traveling.  You can secure the hose with the Velcro straps on both ends of the tank. You can also remove the hose when you are not using the Road Shower, but do not want to remove the tank.

We also suggest putting a hose clamp or some retainer on the end of your bar if your shower is mounted on the ends of your bars. That way if it slips, it won't go over the end. If the included mounts do not work well with your rack, please purchase another mount bracket, such as Yakima Mighty Mounts, or Rocky Mounts Universal wraps. Please see our accessories page.


Bracket holes are 4.25" apart. If you bars are wider than 4" than these will not work.

7) Can I add a longer hose?

Yes. You can screw another hose on the end of the Road Shower 2 hose or the Road Shower 2 elbow. We sell 8' hoses in our online store. You can also add a small compact hose, like a pocket hose, that are 25 - 50' long. They work fine.

8) Can I mount the Road Shower to a roof top cargo basket?

Road Shower 4 comes with a slot on the back side. You can use that to mount directly to your roof top basket. We recommend 3 mounting points at least. So please purchase another set of mounting brackets if you have only 2 and plan to mount to the side of your roof top baske

9) Can I use a compressor to pressurize the Road Shower?

Yes you can. These work much better than a bike pump. Set your compressor to 65 PSI. The pressure relief valve will release at 55-75 PSI, depending on if it got wet, heat of the tank, and other factors. If it is releasing at 55 PSI, then set your compressor to 54 PSI and don't go over that.

We use an inexpensive 12 volt tire compressor. There are dozens to choose from. They cost around $30. This one is good. Air pumps that are rechargeable are nice. You don't need to plug them into the cigarette lighter. This one is good. The little cheap ones won't work.

If you want a higher quality rechargeable compressor, you can get a Ryobi air pump. And you can use it as a drill as well. Very nice to carry on a camping trip. Click below to see the video on how that one is used.



10) Can you cover up the Road Shower for insulation and keep the water warm?

Yes...if you fill it with warm water and put your cover on, it will stay warm for several hours. (This cover was custom made by a local upholster. We do not sell them at this time. However we should have a cover by summer of 2018.

11) Can you mount the Road Shower to the gutter of a vehicle.

Rocky Mountain Westy and GoWesty both make mounting brackets for the Westy's to mount your Road Shower to the gutter.

Here was an older work around. Mike in France did it this way.

Here's how to install you road shower to a T4 camper: Buy the standard T4 awning support brackets about 50€. Bend them back with a hammer and work bench. Follow instructions to install awning normally. Hey presto you can now enjoy using your roadshower even when you're wild camping, or at the beach with your pop up, up or down!

Here is another:

11b. Can you mount to the hood of a Jeep. Yes. Contact 4x4Fabworks for the brackets.





12. I can't reach the top of the Road Shower very well in order to pump it up. Is there some kind of air hose extension avaialable?

Yes there is. You can buy a 10' air hose extension for about $20.

Here is the photo and the link.

13.One question, has anyone frozen one and does the tank split?

Good question. I have had one freeze many times. It got down to about 18F. The tank did not split. The elbow did split. I have also had the nozzle split. All easily replaceable.

It will take a light freeze for sure. If the tank was completely full, it might split or bend the tank during a hard freeze. I would treat it like any other RV plumbing in the winter. Drain or insulate when expecting a hard freeze.

14. Can you mount it vertically?

Yes you can. The fill cap will need to be on the high end. Please see photos below.

15. Can you fill and pressurize with a hose like Rinsekit without pumping?

Yes, just attach your garden hose to the end of the Road Shower hose using a female coupler available from Lowes for $2. See our video here on how to do it.

A garden hose connector comes with the Road Shower 4. Just check your pressure on the tank and don't go over around 60 PSI...or you wil blow water out the pressure relief valve. If you water supply pressure under 65 PSI, you don't have to worry about it.

16. Can you put more water in than the stated capacity?

Road Shower 4S - 4 gallon - hackable to 5.5 gallons.
Road Shower 4 - 7 gallon - hackable to 9 gallons.
Road Shower 4L - 10 gallon - hackable to 13 gallons.

By hackable, we mean it could carry the extra water, if you fill the air chamber with water. To do that, you fill with a garden hose and drain air from the Shrader valve at the same time. This is only recommended for long trips with no water access.

If you hack for more water storage what’s the max pressure you recommend to get the water back out?
You would drain some water from the tank first...maybe a gallon and then start pressurizing. You would need to drain it by opening the fill cap to allow air in as you press open the spray nozzle. After draining a little you can then pressure to 65 PSI. However, unless you drain the entire hacked air space you would not be able to pressurize once and empty the tank.

17. How long does the water run?

You can get longer run times by dialing the pressure back with the black handle on the elbow and/or the nozzle adjustment on the tip. Up to 10-15 minutes.

The high pressure is good for cleaning gear. Dial the pressure back for showering.

The optional shower head will run much longer because it is a low flow shower head. Pressure can be controlled by the black handle on the elbow.

18. What if I am parked on a hill and the outlet is on the uphill side?

A 2nd outlet is designed to be used when the RS is tilted one way or the other to get the most water out. You can use it if you buy another on/off elbow (hose bib).



19. I experienced some fading with Road Shower 2. What can I do?

Any finish will fade or discolor over the months or years in the sun. Road Showers will still function well with a faded powder coat. To prevent or slow down fading in the first place, use a high quality auto wax. We use a spray on kind, and rub it in. It will protect the finish. If your old Road Shower is already faded, you can spray paint it black with High Temp black grill paint. We recommend removing the hose when not in use (between camping trips), to prevent discoloration.

20. How can I mount a Road Shower 4 to a Frontrunner rack? This technique should work with the T-Slot on the Sprinter van. You can buy the mount from the link below for about $50.


See this video. What he does not show is the actual mounting of the Road Shower. You would slide the carriage bolt into the T-slot of the Road Shower 4 to where you want it positioned. Lift the Road Shower and drop the threaded end of the bolt through the single hole in the tent mount kit. Repeat for the other bolt and mount. Then use the included nylock nut to secure the bolt to the mounting bracket.

22. The water from the Road Shower has a hose taste. What is wrong?

We use non-toxic food grade hose similar to the brewing industry. Heat and sunlight hitting the hose when the hose is full of water can cause some hose taste. Heat causes the same issue in the brewing industry. It won't hurt you. To avoid it, turn the water off at the tank and drain the hose after use. To get drinking water, turn water on at the tank and run some water through the hose and discard. Then use the water for drinking or cooking.
