While hot tubs can be enjoyed pretty much anytime of the year, for most it’s a summertime activity. Here are some of the weirdest ones on the planet.

The Bug Tub

We’re not sure what’s up with Europeans and unusual hot tubs, but if you’re looking for a unique one that can enjoyed at lower elevations, you might want to have a look at the Bug Tub. This one was built out of a red Volkswagen Beetle. While it’s only currently available for rent over in the Netherlands, it could be only a matter of time before its owners decide to build more to sell around the world. Since its debut in the summer of 2014, the Bug Tub has appeared at various music and food festivals around the Netherlands.

The HotTug

Have you ever wanted to enjoy Jacuzzi jets while aboard a boat but you can’t afford a yacht? Well, then a HotTug might be right for you! These wood-fired watercrafts combine the pleasures of pure bathing culture with the steadfast reliability of a tug boat. The HotTug was developed by a Dutch designer named Frank de Bruijn. The first ones could be spotted cruising up and down the canals of Amsterdam back in 2012. Other HotTugs can be rented in cities like London where bathers use them to buzz down the Thames for £120 an hour. If you don’t want to travel all the way to Europe to try one out, de Bruijn recently announced plans to start selling them in the United States. Cost: They start at $16,587.

The Daredevils’ Jacuzzi

In 2011, a group of 25 fearless individuals decided to build a hot tub and suspend it off the side of the Gueuroz Bridge in Valais, Switzerland (it’s one of the tallest in the world). It took them around six hours to attach a wooden platform to a series of cables and place the tub, a heating unit, and bubbling water on top of it. Then they all lowered themselves down into the tub from the bridge and had one of history’s most daring group photos taken of themselves enjoying a 2.5-hour soak 500 feet over the canyon below. (This isn’t the first time they built an “extreme jacuzzi” either—they plopped one on the peak of Mont Blanc, the highest mountain in the Alps, in 2007.)
