Best Splurge: The Plunge

The Shark Tank–endorsed Plunge is a definite investment, but one regular plungers told us is worth every penny. At about 75 gallons, the capacity isn’t as high as some other models, but it’s designed more like a sleek bathtub for comfort. And for style points, which is important if you’re giving your plunge tub a prominent and permanent spot in your home or backyard.

We love that the acrylic and fiberglass tub boasts a heater and a chiller, making it a highly versatile pick. You can set the temp to as low as 39°F and as high as 103°F. It’s even equipped with a sanitation system to keep the whole thing clean. “I love the recirculating water, consistent temp, and the quality/size of the tub,” says Courtney Fisher, a fitness expert and regular plunger. The tub comes with everything else you need to enjoy the experience, such as a cell phone holder and a cute little rubber ducky. “My Plunge unit lives outside, and it has survived snow, rain, wind, and shine. I’ve had my plunge for over a year and it looks brand-new,” says Fisher. Adding to peace of mind? You get a one-year warranty—just in case.
