WHY JAMES CHOSE THIS

From skeptic to daily plunger in 11 minutes a day

James spent two weeks comparing cold plunges before calling us. Here is what pushed him to the All-In, what the first week was like, and what has changed 6 months later.

Questions we get before people buy this

You can, and we will not talk you out of it. The reason buyers use us is that we carry all three major brands and give you an honest comparison before you commit. If the Sun Home is actually better for your situation, we will tell you that. Plunge's own site will not.

Compared to a gym membership at $120/mo, you break even in about 3 years and own the unit forever. Compared to buying ice ($80-$150/mo for daily plunging), you break even in under 2 years. The financing option at $65/mo makes the math cleaner. Whether it is worth it depends on how consistently you will use it.

The All-In uses a variable-speed fan that adjusts based on load. At full cooling it is similar to a quiet air conditioning unit. At maintenance temperature it is barely audible. Most users run it overnight without it being a problem.

No plumber needed - you fill it with a garden hose. You do need a dedicated 120V 15A circuit, which most homes already have. If you are unsure, call us and we will help you figure out your setup before you order.

Yes. Cold therapy is eligible for HSA/FSA spending under the medical expense category. At checkout you can pay with your HSA/FSA card directly. This effectively reduces the price by 20-30% depending on your tax bracket.
