Sun Home's Cold Plunge Pro pays off where several people plunge every day, and the Luminar depends on whether your pad and your panel can carry it. Alongside two lines of infrared cabin, the brand sells an outdoor flagship and a blanket, plus a cold plunge that competes with equipment gyms buy. We priced and specified all five from the current range, starting with the two that draw the most attention.

Sun Home runs two cabin lines under an outdoor flagship

Two cabin lines run alongside each other. Solstice is far-infrared only, and on Sep 29, 2026, Sun Home listed it at $6,199 for the two-person and $8,599 for the four-person. Equinox trades some of the far-infrared panels for a pair of 500W full-spectrum heaters. It costs $6,799 for two people and $7,699 for three.

The Luminar sits above both as a weatherized five-person outdoor cabin at $14,499. Two products belong to neither line, and they get most of the search traffic. They're the $499 infrared blanket and the $14,599 cold plunge.

Try the options

Outside

  1. It's one sheet of glass on two hinges, with a pull handle inside and out.

  2. Sun Home builds it from kiln-dried eucalyptus with a black finish outside. The cabinet measures 50.9 by 45.9 inches and stands 77.7 inches tall on its feet.

  3. Sun Home put it outside so the cabin can warm up before you get in. The main controls are on the inside wall.

  4. It's 10 feet long and needs a dedicated 120V, 20A outlet (NEMA 5-20), so put that outlet on this side of the room.

  5. Give it a level, dry floor indoors with 4 inches clear on every side and a foot above the roof. It weighs 522 pounds.

Inside

  1. They sit behind wooden slats across the back wall, along both sides and in a narrow panel beside the door. Sun Home rates their EMF output at virtually zero.

  2. It's 45.2 inches long and 20.2 inches deep. Inside, the cabin measures 45.4 by 39.9 inches and 70.3 inches high.

  3. It sets the temperature and the length of the session. The Solstice runs at 130 to 140°F.

  4. Two chromotherapy lights sit in front of a pair of Bluetooth speakers, so your own music can play through a session.

We built this model from Sun Home's 3D tour and spec sheet, so small details can differ from the sauna that arrives.

The Cold Plunge Pro pays off when several people plunge daily

The Cold Plunge Pro deserves the attention it gets. It holds 150 gallons, and Sun Home rates its 1 HP chiller down to 28°F, which is far colder than you'll need to plunge. Sun Home doesn't publish how fast the Pro pulls the water back down after someone climbs in, and that recovery rate decides whether two people can plunge back to back. Its spec sheet gives only the first cool-down, about eight hours to 38°F.

The rest of the money goes into filtration. A 20-micron sediment filter catches what coarser cartridges pass, and ozone injection and UV sanitation work behind it. Between them they set how often you drain and refill a tub that weighs the better part of a ton when full. For all that cooling, the Pro plugs into a standard 120V outlet. Sun Home asks for a dedicated 15-amp circuit with GFCI protection, so check the breaker before it arrives. Leave 3 feet clear at the chiller's vent end and a foot on each side too.

At $14,599 the Pro is priced for a household or gym where several people go in every day. Business Insider named it the best plunge it tested. One person plunging once a day is buying capacity they'll never reach. We'd point that buyer to the entry tier in our cold plunge guide, which gets the same cold water for a fraction of the price.

Where to buy

At $14,499, the Luminar hinges on weight and wiring

The Luminar packs ten full-spectrum heaters into a cedar-lined shell of what Sun Home calls aerospace-grade aluminum. Four of them stand against the front glass, and the other six sit behind the backrests. Five far-infrared panels add heat lower down. Three sit at calf height under the benches, and two lie under the floor grates.

Sun Home's warranty page covers the exterior cabin for three years, and the cabinetry and heaters for a lifetime it defines as seven years. We'd still call a five-person cabin an excellent one-person cabin, so if the footprint and the budget both fit, the seat count shouldn't hold you back.

Its weight and its circuit decide whether you can have one. Sun Home lists the cabin at 1,070 lbs and asks for a level pad that supports at least 1,270, so plan the pad and the freight together. It also wants 240V/30A on a NEMA L6-30 outlet, and an electrician prices that work from your panel's spare capacity. Sun Home's quote can't tell you what it'll cost.

The Equinox adds near- and mid-infrared to the Solstice

The indoor choice comes down to whether you want near- and mid-infrared at all. Solstice is far-infrared only, with nine heaters drawing 2,006W in the two-person and ten drawing 2,750W in the four-person. A seven-year warranty covers its cabinetry and heaters.

The Equinox cuts the far-infrared panels to 4 in the two-person and 5 in the three-person, and it adds a pair of 500W full-spectrum units in either size. Both lines come with Bluetooth audio and chromotherapy lighting.

The most argued question in infrared marketing is whether the extra bands are worth $600 on the two-person, and our decoder takes those claims apart one at a time. The clinical literature rests on far-infrared, so we read the near- and mid-infrared additions as extra capability and don't count on them to multiply the benefit.

The circuit deserves more of your attention. Everything up to the three-person Equinox runs on 120V, though Sun Home wants a dedicated 20A circuit with a NEMA 5-20 outlet. The four-person Solstice steps up to 240V/20A and needs an electrician.

Where to buy

The blanket suits renters and anyone still testing the habit

For $499, Sun Home sells a 500W far-infrared blanket that reaches 167°F, with a timer that sets up to an hour. It unfolds to 71 inches square over a wipe-clean PU interior. Rolling Stone called it the best infrared blanket of 2025, and it undercuts HigherDOSE by $200.

A blanket presses heat against your skin with no hot room around you, so you give up löyly and hot air to breathe. The gap to a cabin runs larger than the price difference suggests. For a renter, or for anyone finding out whether the habit survives three months before committing five figures, we'd call it the cheapest real way in.

Where to buy

Read Sun Home's EMF figures as a manufacturer's floor

Sun Home gives an EMF figure on two product pages, 0.5 mG for the Eclipse and 0.4 mG for the blanket. Its Equinox and Solstice pages say ultra-low or virtually zero without a number, and so does the Luminar's. The safety page cites a Vitatech summary that reads 0.6 to 4.0 mG at a foot and names no model. We read any published EMF reading as a manufacturer's floor. It's taken at a stated distance from a stated panel, and a few inches in any direction changes it. So the number tells you the company designed for shielding without telling you what your body sees. If low EMF is the spec you're shopping on, that design still counts for something.

Before ordering, we'd settle the circuit first and the delivery second. Price in the electrical work, since it's the cost that gets forgotten, and expect freight on a 1,070 lb cabin to run higher than a first guess. Then ask what promotion is live that week. Sun Home discounts often enough that the first number you're quoted is rarely the last one.

Common questions

Is the Sun Home Cold Plunge Pro worth $14,599?
Yes. The Sun Home Cold Plunge Pro earns its price in a household or gym with several daily users, since its 1 HP chiller and 20-micron filter with ozone and UV are built for water that never gets a rest. It runs on a 120V outlet. One person plunging once a day won't reach that capacity, and an entry chiller holding 39°F costs a fraction and delivers the same cold.
How cold does the Sun Home Cold Plunge Pro get?
Sun Home says the Cold Plunge Pro gets down to 28°F across its 150 gallons. Its spec sheet puts the first cool-down at about eight hours to 38°F, and Sun Home doesn't publish how fast the water recovers after each use. Most cold adaptation happens anywhere from about 50°F down into the high 30s.
What is the difference between the Sun Home Solstice and Equinox?
The Sun Home Solstice runs far-infrared heaters only. The Sun Home Equinox adds two 500W full-spectrum units for near- and mid-infrared and carries fewer far-infrared panels. The two-person Equinox has 4 where the Solstice has 9, and it costs $600 more. The infrared studies people cite, like the Waon trials in heart-failure patients, used far-infrared heat in supervised clinical sessions. So we'd count the Equinox's extra wavelengths as a feature to weigh and wouldn't assume a bigger health payoff.
Does the Sun Home Luminar need special electrical work?
Yes. The Sun Home Luminar runs on 240V/30A through a NEMA L6-30 outlet, so an electrician has to run a dedicated circuit priced on your panel's spare capacity. Plan for freight and the pad too. Sun Home lists the Luminar at 1,070 lbs and asks for a level pad rated for at least 1,270.
Is the Sun Home sauna blanket better than HigherDOSE?
On specification we'd call the two closely matched, and the Sun Home blanket costs $200 less at $499. It reaches 167°F on a 500W far-infrared element, and Rolling Stone rated it the best infrared blanket of 2025. Price is the clearest reason to pick one. Neither replaces a cabin.
