The full story
Frost proves you do not need a backyard to plunge every day. The same 37°F chiller, the same filtration, in a footprint that slips onto a balcony or into a garage corner. If space is the reason you have not started, Frost removes it.
Cold, on demand
The cold is always waiting.
“Fits my tiny apartment balcony”
I did not think a real cold plunge could fit up here. Frost does. Cold, clean, filtered, quiet.
“Balcony setup, zero drama”
Up the elevator, filled with a hose, plunging the same evening. My neighbours still have no idea it is out there.
“Small tub, real cold”
Same 37°F as the big units in half the footprint. Do not let the size fool you - the cold is not compact.
“Brilliant, lid could be lighter”
Use it daily on a small terrace. Only niggle is the lid is slightly awkward in a tight space. Would still buy again tomorrow.
“Garage corner convert”
It lives between the bikes and the shelves. Two minutes every morning before the kids wake up. Life-changing is overused, but still.
“City living finally allows cold”
No backyard, no problem. Standard outlet, no plumbing, and the filtration means I am not hauling water around an apartment.
“Two minutes that run my day”
The chiller pulled the water down to 39°F overnight and it has not moved since. Setup was genuinely under an. The product is great; support took a few days to answer my setup question, hence three stars.
“The chiller is the hero”
Coming from a DIY ice-bath setup, the difference is night and day. Setup was genuinely under an hour from pallet to plunging. Whole household uses it, even the skeptic.
Questions, answered
Do I need a plumber or electrician? +
The plunge runs on a standard 110V outlet in the US (13A UK/EU) and needs no plumbing - you fill it once and the filtration keeps it clean. Saunas plug into a standard outlet; the barrel sauna needs a dedicated 240V line, which we flag before you order.
How cold does the plunge get, and how hot the sauna? +
Every plunge chills to 37°F (2.8°C) and holds any temperature you set. Infrared saunas reach 150°F, the traditional barrel reaches 194°F (90°C).
What does freight and delivery look like? +
White-glove in the lower 48 - we deliver, place and start it for you. UK & EU ship curbside with a two-person crew option. All freight is included in the price you see.
Can I finance it? +
Yes. Affirm and Klarna are built into checkout. Most builds split over 6 to 24 months, from $0 down, with a soft credit check that will not affect your score.
How do I keep the water clean? +
A 20-micron filter plus ozone and UV keep the plunge clear for 3-4 weeks between changes. We send a maintenance kit with every plunge and a simple 2-minute weekly routine.
