Hot showers, like electricity, are a luxury that’s easy to take for granted. That all changes after a few nights camping at a music festival, a week toiling at a backcountry job site, or overlanding all summer in the great unknown. An itchy scalp and the vague smell of warm clams suddenly make the idea of spending hundreds on a portable shower seem less absurd.
I’ve been testing the Hottap Go from Australia-based Joolca while vanlifing to shower after surfing and to wash up after cooking. It features a 12L integrated water tank which is an improvement on other portable showers that require an external container and long, cumbersome hose that’s easy to trip over. The Hottap Go also recirculates the water until it reaches your chosen temperature. This slows things down a bit, compared to “instant” portable showers, but it doesn’t waste water since it won’t produce an initial shock of cold water that’s usually sprayed into the ground.
The $554 Hottap Go requires an external 12V power source, but in the US Joolca sells a 12V / 5A $165 power bank that attaches magnetically to the case. In Europe I had to roll my own with an €85 (about $100) power bank found on Amazon. The result is a true, fully self-contained hot water system that can be taken anywhere.
$554
The Good
- All-in-one solution for hot showers anywhere
- Water tank large enough for two showers
- All accessories and attachments store inside the unit
- No water wasted unlike competitors
- Temperature remains steady
The Bad
- Very expensive
- Battery is optional and attaches to the outside of the case
- Have to wait a few minutes to heat up
- Water pressure is just okay
To clear up any confusion right away: the Hottap Go requires electricity to power the integrated water pump and display but it heats the water with propane gas. It works with standard 1lb propane canisters out of the box, and larger tanks with a hose and regulator you must provide.
One thing I love about the Hottap Go is that the hoses, battery, showerhead, and gas canister can all be stored inside the water tank when not in use for easy portability and storage. I also like that the flow-adjustable showerhead comes with a magnetic holder. Taken together with its approach to preheating the water through recirculation, it’s clear that Joolca’s product designers have learned from the shortcomings of the current crop of portable propane showers.
To shower, you first attach the quick-release hoses for the gas and showerhead, plug the shower into a 12V power source (power bank, power station, or the cigarette plug inside your car), set your desired temperature and wait. The unit will begin heating and recirculating the water until a series of beeps indicates that the target temperature is reached. I brought tap water up to a hot 47C / 117F (per the display) in exactly four minutes, which was just enough time to gather everything I needed to shower outside my van with my modesty preserved.
My makeshift shower stall between the rear doors of my van. The Hottap Go is hot and ready to go by the time I hang the towel.
It also serves as an outdoor cleaning station to keep the messy dishes outside my living space.
The magnetic showerhead holder is super convenient. It attaches to the body of the Hottap Go or pretty much anywhere and any angle on my van.
The on/off button on the showerhead lets you conserve water as you lather. The grey dial adjusts the flow rate.
On one windy day at the beach, I noticed the Hottap Go had to keep reigniting, despite its leeward venting. It failed so often that I saw an E3 error message on the display. Repositioning the shower out of the wind kept the flame lit. The handle on top makes it easy to move, and the seal around the lid ensures that water won’t slosh onto the ground or your power bank. Otherwise, the Hottap Go always lit and stayed lit without issue during my testing.
Joolca says the Hottap Go is good for two “great showers” or a single “long, luxurious one.” I was able to take two functional yet satisfying showers from its full 12L (3.2 gal) water tank, making liberal use of the on/off switch on the showerhead to conserve water while lathering.

Water flow is just okay, even at maximum setting. It’s strong enough to penetrate long, thick hair when shampooing but it’s not going to jettison grime from my mountain bike, for example. The magnetic holder is strong and the showerhead feels good in the hand with a nicely positioned on/off switch. Adjusting the flow rate dial is a two-handed operation, but mostly I just left it on max.
If you’ll only use it once or twice a year, then spending over $554 for the Hottap Go portable shower doesn’t make much sense, especially when tankless portable showers like BougeRV’s cost half that. I much prefer the Hottap Go’s recirculating water tank, performance, and overall convenience, though I do wish the optional $165 magnetic power bank was included in that price. Still, for vanlifers like me or anyone who regularly spends days away from plumbing, $719 can be easily justified for what could be the best portable hot water shower available.
