Wood Fired Hot Tub Coil Kit
Our coil kit can be attached to your own tub to convert it into a wood fired hot tub. Everything is included for quick and easy installation, all you need is a power drill and the tub.

500L Uninsulated Tub - 1.5 hours
800L Uninsulated tub - 2 hours
1,000L Insulated tub - 1.5 hours

2,000L Insulated tub - 3 hours
No Electricity Needed! But How?
You only need two things to work your wood fired hot tub: water and wood. As the water is heated in the coil it begins to rise (hot water rises just like hot air). The water follows the spiral of the coil up and back out into the tub. Cold water from the bottom of the tub is sucked into the bottom inlet of the coil which starts a steady flow without a pump. This scientific phenomenon is called thermosyphon.
Quick and Easy Installation
Installing the Coil Kit to your tub takes about 20 minutes and the only tool you need is a power drill. Simply drill two holes in the side of your tub, screw in our universal through wall ports and connect the coil using the easy to connect fittings. The video below shows a quick overview of the installation process.
BBQ Grill Functionality
Place a grill, hot plate or large wok over the coil to enjoy flame grilled food while the tub heats up.

Customer Reviews
We have had other woodfired hot tubs with a Salty Barrel Hot Tubs kit is absolutely the easiest to install and so efficient. It works great. Even in the temperatures we experience in Alaska. I’ve used it in the dead of winter and we have been using it constantly for nearly a year now since purchase. The installation is so easy that we had ours assembled and fired up within hours of receiving it.
Thank you for making such a great product
With a 100 gallon stock tank, I have an off grid tub that takes just 15 minutes to fill and about 2-3 hours to heat. The physics works just like it should and the quality of the tubing and hoses is excellent.
I attached the coil to an old cast iron bath. Lined up two side by side facing the sunset. The result was an awesome and unique experience for our glamping guests
We have an off grid property on the water and wanted to enjoy a hot tub under the stars without having the noise of a generator. I came across Salty Barrels website. We purchased a 90 gallon stock tank and the set up was dummy proof. The quick connect set up is exactly that in less than 5 minutes we were ready to get a fire going!
With hard wood it takes 2 hours to bring 90 gallons of mountain fed water (which is always ice cold) to a dreamy 105 degrees. The Coil is simplistic and functions without any electricity or propane. We’ve had ours for over a year and use it 4 days a week 12+ hours a day (we keep it going for the wknd) and it’s still as solid and sturdy as the day it was delivered. What are you waiting for??? Go get yourself a Salty set up, you won’t regret it!
