    • Refreshing and Worth Every Penny!
Absolutely A Refreshing Addition To My RV Life. Having an Extra Shower Is So Cool! Simply A Must Have!

    • Works Great!
We love this! Works perfectly! Our bathroom is being replaced and this has been the perfect outdoor shower for our whole family. May never go back to showering indoors! Easy set up and easy for everyone to use. Highly recommend.

    • Water heater is good, does the job.
Got this heater for my pool area. We have a small pool house for changing clothes but no hot water. This solves that! And one tank of gas with this heater lasts a long time for us. The water heater is easy to connect, easy to hang and easy to vent out with a B-vent. The hot water is decent. It can be plumbed to a fixture, that is what I did. I used pex and a threated fitting to connect it to the water heater. If you just want to be basic, then there is a shower want included with it for at the point use. Overall the quality is very good. Highly functional and simple. It's really a point of use system for maybe one or two hot water fixtures, max. It's for small runs. If you have a 20 to 30 ft run with 3 or 4 fixtures that are always on, this won't be for you. It's on the pricer side of this type of product. So I will leave it for you to decide if it is a good value or not. ... show more

Once we had the heater installed and hooked up properly, it forked up instantly and provides endless hot water. It’s great for our outdoor shower.

    • A real treat for camping!
I ordered this for camping and cannot begin to describe how nice it is to be able to camp off grid outside of a park in truly peaceful natural settings AND be able to take a warm shower and wash dishes with hot water! It is like the best of both worlds! I have had no issues with operating this and it functioned perfectly straight from the beginning. It is super easy to set up and can simply be secured to a tree branch. The water pressure isn't what you get at home from your shower, but it is still good enough to wash your body and hair and rinse everything away, and far better than the gravity fed bag showers. ... show more
