How Fast Can Your Hot Tub Go?

Most hot tubs stay in one place. And most carpools keep you dry. Two enterprising young men brought the two together, taking “carpool” to a whole new level and the hot tub on the road.

The Guinness Book of World Records reports that Canadiens Duncan Foster and Phil Weicker, enlisted a Los Angeles, California, USA-based crew to convert a 1969 Cadillac DeVille into a hot tub on wheels. They named it Carpool DeVille.

The 472-cubic-inch V-8 convertible had its chassis strengthened and interior replaced with a single-piece fiberglass tank especially molded to fit in the classic car.

The steering column was made watertight, and a liquid-to-liquid heat exchanger with engine coolant ensured that the water could be heated to 102°F in about 35 minutes.

On 10 August 2014, the two inventors tested Carpool DeVille near the Bonneville Salt Flats in Utah, driving an average speed of 52.28 mph in their two best runs, reaching a maximum speed of 54.8 mph in the third and best run.

Fitted with 11 water jets, a spa filter and an overflow tank, the tank can sit five and carry up to 375 gallons of water.

The car was bought for $800 from eBay in 2008. Its conversion took six years to complete, with some of the funds crowd-sourced through Kickstarter.

Jay Leno took a spin in it in 2017. And it’s even got its own Twitter page!

In 2018, the Carpool sold at a Barrett-Jackson auction, fetching $26,500.

The only suggestion we have is this: They should’ve used FROG^® @ease^®. They would have had Cleaner, Clearer, Softer^® water that was Easier to care for. Plus, they would’ve used up to 75% less chlorine*. Next time guys, FROG would like to go on a ride with you!

*Compared to the minimum ANSI recommended chlorine level of 2.0 ppm for a hot tub.
