Cold plunge · all in one
Edge Tub Elite
A portable insulated tub bundled with a 1 HP Wi-Fi chiller that cools to 37 F or heats to 105 F, with micron filtration. Note: Edge Theory Labs has gone out of business - its own homepage now states so and points owners to a third party for replacement chillers. Treat this as a discontinued unit with no factory warranty or parts support; the price shown is the last-known figure.

How it scored
Cooling
10.0/10 · 30%Whether the unit actively chills, and how cold it gets. An ice-only tub is not a self-chilling plunge.
- +6Built-in chiller Apowered chiller included - Cools the water actively, with no need to buy or add ice.
- +2Reaches 45 F or colder B37 F - Reaches at least the 45 F range used in most cold-immersion protocols.
- +2Reaches ice-bath cold B37 F - Reaches 39 F or colder, true ice-bath territory.
Water Care
3.0/10 · 20%Ozone, UV, and filtration that keep the water clean between changes.
- +3Filtration / circulation Bfilter + pump - A circulating filter keeps debris out and water clear.
Build & Insulation
10.0/10 · 15%Insulation (holds temperature, lowers running cost) and full-immersion capacity.
- +6Insulated Binsulated shell/cover - Insulation holds temperature and lowers the chiller's running cost.
- +4Full-immersion capacity C80 gal - Large enough for full-body immersion.
Value
7.0/10 · 20%Running cost - the chiller electricity brands rarely put on the box.
- +5Chiller running cost vs class A~$300/yr electricity (below class median) - Estimated annual chiller electricity, scored against the chiller-unit median. The cost brands rarely disclose.
- +2Insulation lowers running cost Binsulated - Insulation reduces the electricity needed to hold temperature.
Practical
3.0/10 · 15%Warranty, electrical-safety listing, and plug-and-play convenience.

What to know before buying
- · Edge Theory Labs has reportedly ceased operations; confirm the unit is still sold and that warranty and replacement parts are available before buying.
- · Includes a built-in chiller that holds a set temperature without ice; manufacturer lists a minimum around 37 F.
- · Positioned as a more portable, relocatable tub than fixed-install premium units, at a mid-premium price near $4,990.
- · Confirm exactly which water-care components are included, since you reuse the same water between sessions.
- · Runs on standard power; factor in ongoing electricity to run the chiller.
FAQ
- Can I still buy the Edge Tub Elite and get support?
- Per our catalog, Edge Theory Labs has gone out of business, with its own homepage saying so and pointing owners to a third party for replacement chillers. We treat it as a discontinued unit with no factory warranty or parts support, and the listed price is the last-known figure.
- What did the unit include when it shipped?
- It bundled a 1 HP Wi-Fi chiller that cooled to 37 F or heated to 105 F, with micron filtration and an insulated PVC tub, so in our scoring it earned its Cooling credit as a self-chilling plunge. The warranty risk, not the cooling, is the main reason for caution here.
