It’s also worth mentioning

This is a liquid propane-powered shower, but the best part is that it comes with a CSA approved regulator as well as a 9 foot long hose, designed to work with a 20lb propane gas tank. 

Another feature that we also loved (and one that you’ll definitely love too) is the high BTU’s that this unit delivers. With an impressive 74,500BTUs, it packs in enough power to deliver impressive performance.

Better yet, the hose is made using stainless steel, and with an upgraded chrome showerhead, both designed to give you lasting service and top-notch performance.

Best For Energy Efficiency – GASLAND Outdoors 6L Portable Gas Water Heater

Questions and Answers

Question: How long does it take to warm water?

Answer: This comes down to the model you go for, some units will have your water hot enough as fast as in a few seconds while others take several minutes. Make sure to decide depending on what your personal needs are.

Question: Can I purchase additional components?

Answers: Some portable hot showers don’t come with all the components included in the package, so you might need to pick up some.

However, if in case a component is broken, the best thing to do is contact the manufacturer to find out if they have a replacement before heading for the store down the road to pick one.

Question: Does it hold water?

Answer: This will depend on the design of the unit you are after. Some come with a water reservoir, while others do not.

However, it’s worth keeping in mind that most of these units are “tankless”, which means you will need to have a water source, and all they do is heat it.  

Question: Is there an inbuilt filter for the water?

Answer: Well, some of the units we’ve listed here come with filters, but that’s not to say that all of them do, it’s thus best to check carefully if the one you have your eyes set on comes with this feature.

Also, keep in mind that a filter only holds back the debris, but it won’t clean any chemicals or bacteria in the water.

 Buyers Guide To Choosing The Best Tankless Gas Water Heater

Now that you have been exposed to some of the best options around and some of the ins and outs of portable hot showers, here are some other things you need to be keen on when buying.

The material

It’s by far one of the most important factors you need to consider when making your final decision since some materials are not ideal when it comes to handling hot water.

Also, such materials as plastic on the components of these units could be prone to breaking easily. So it’s advisable to look for anti-rust material if you want to get the best out of your purchase for long.

Power

Another important aspect that you need to be keen on is just how powerful the unit is, and this usually comes down to the BTU/Hr that it can deliver.

This will determine how fast it can get the water hot, which could mean all the difference when it comes to saving those precious minutes in the morning. Also, check the level of gallons per minute that your shower of choice can deliver.

Weight and portability

These units are ideal for car campers, but other campers could also make the most of them. Whichever your case, however, you need to ensure you get a unit that you can move around or transport with ease.

The more lightweight the better, and thankfully, most of them are quite lightweight enough. Also, such features as a compact design and a carry bag also come in very handy, so yeah, be on the lookout for those too.

These are not really suited for overnight stays outdoors these units are for staying in one place for several days. A handy small item for overnight stays somewhere and you want a hot shower is a solar-powered shower pack like the Advanced Elements Solar Shower

Ease of installation

While portable hot showers make a great addition to your camping fun and convenience, the installation turns out to be one of the things that hold back most people.

A unit that is complicated, or doesn’t come with all the parts and components necessary for the installation isn’t the best bet.

And if the installation is too complicated and you are not a handy person, you might be in for some serious frustration. It’s best to read a few reviews to find out how others have fared with this part.

Final thoughts

If you’ve had it with cheap and crappy knock offs when buying portable hot water showers, then it’s time to put an end to that with a reliable unit that offers the value you pay for.

This list has all the units you want to give your family and friends that hot morning shower when in the outdoors. And since you’ve also learned what makes a good portable hot water shower and what to expect out of your unit, you can shop with confidence.

Get your ideal shower and bring back the fun to your outdoor adventure.
