The Therasage Thera360 Plus and the Peak Saunas Mini are both one-person infrared saunas that run off a normal household outlet, and that is roughly where the overlap ends. The Thera360 Plus is a 24 lb tent that folds into a carry bag, with your head outside the top, at $1,428 (verified 2026-08-24), or about $1,285 with our code LIFESPANVAULT. The Peak Mini is a 31 by 32 inch Canadian hemlock cabin with a front-wall red light panel, at $5,450 (verified 2026-08-17). The direct answer: buy the Therasage if you rent, travel, or want to prove the habit before committing cabin money; buy the Peak Mini if you have a permanent corner, want to sit inside an enclosed head-in cabin, and want a red light panel with published wavelengths and irradiance in the same purchase.
The $4,022 between them is a format gap more than a quality gap. One is fabric that lives in a closet between sessions; the other is furniture that arrives in a crate and stays where you build it. Both are full-spectrum infrared by their makers' descriptions, both are single-person, and both skip the electrician. Below we walk the specs each brand publishes, flag which figures are brand-stated rather than independently measured, and give verdicts by buyer type. There is no single winner here, only a right answer for your space and budget.
Quick answer
- Renters, travelers, and first-time sauna buyers: the Therasage Thera360 Plus at $1,428 (about $1,285 with code LIFESPANVAULT), because it folds into a bag, weighs 24 lb, and draws 900W from any standard outlet.
- Solo users with a permanent corner who want a real cabin: the Peak Saunas Mini at $5,450, because it is an enclosed, head-in hemlock cabin in a 31 by 32 inch footprint on a 120V/15A plug.
- Buyers who want infrared heat plus a red light panel they can compare on paper: the Peak Saunas Mini at $5,450, because Peak publishes the panel's eight wavelengths and a stated 175 mW/cm2 at 6 inches.
At a glance
Prices come from each merchant's own Shopify product feed on the date shown. Every spec below is as the brand publishes it; neither unit has independent measurements in our data.
| Product | Verified price | Format | Heat (brand-stated) | Power | Footprint | Red light |
|---|---|---|---|---|---|---|
| Therasage Thera360 Plus | $1,428, verified 2026-08-24; about $1,285 with code LIFESPANVAULT | Fold-away tent, head out | Full spectrum, 3 full-spectrum panels plus 2 red/near-infrared panels, 100°F to 170°F | 900W, standard 110V outlet (220V variant, same price) | 33" x 33" x 46" set up, 24 lb, folds into a carry bag | 2 red/near-infrared panels; wavelengths and irradiance not in our verified data |
| Peak Saunas Mini | $5,450, verified 2026-08-17 ($7,295 is Peak's own compare-at) | Hemlock cabin, head in, seated | Full spectrum, 8 panels (carbon far plus halogen and quartz near and mid), up to 150°F | 120V/15A standard outlet (NEMA 5-15P) | 31" W x 32" D x 67" H, about 7 square feet; weight not in our verified data | 9" x 12.6" front-wall panel, 8 wavelengths, 175 mW/cm2 stated at 6" |
The two rows that decide most purchases are Format and Footprint. One of these is a 24 lb bag you can put in a closet or a car; the other is a 67-inch-tall cabin that arrives in a crate. Everything else is detail, and the detail follows.
What $1,428 buys: the Thera360 Plus
The Thera360 Plus is a tent-style infrared sauna that sets up to 33 by 33 by 46 inches, folds back into an included carry bag, and weighs 24 lb as a unit (the 63 lb figure you may see on the product feed is the shipping weight). It runs 900W on a standard 110V to 120V outlet, with a 220V to 240V variant sold at the same $1,428; you pick the voltage at checkout. Heat is adjustable from 100°F to 170°F in 5-degree steps on a 90-minute timer.
Inside, Therasage runs three full-spectrum infrared panels (near, mid, and far) plus two red and near-infrared panels, and quotes 98% emissivity for the emitters. The brand builds in what it calls EMF, ELF, and RF remediation, plus an earthing mat and tourmaline-infused panels. The low-EMF engineering is a genuine differentiator against the no-name infrared tents this unit competes with. The rest of the wellness vocabulary attached to those features, the negative ions, detox, and cellular-charge language, is Therasage's own positioning and should be read as marketing rather than a measured outcome.
The design that defines it: your head stays outside the tent. Some buyers prefer breathing room-temperature air while the body heats; purists who want the whole-body enclosed experience do not. It is a difference in kind, not degree, and it is the first thing to decide before you look at prices.
On price, the code LIFESPANVAULT takes 10% off any Therasage product at checkout, which brings the Thera360 Plus to about $1,285. That is a partner code we hold, not a merchant sale, so the $1,428 list stands on the site and the discount lands in the cart. Our Is Therasage worth it piece covers the rest of the brand's catalog if you want the wider context before buying.
Where the Thera360 Plus gives ground
It is a tent. Fabric walls, a head-out collar, and a 46-inch profile mean you will not get the enveloping, head-in feel of a wooden cabin, and it will never read as furniture in a room. The two red and near-infrared panels have no published wavelengths or irradiance figures in our verified data, so you cannot compare them against a standalone red light device the way you can with the Peak. Warranty terms are not in our verified data either, and neither is shipping cost. And while the 170°F stated ceiling is higher than the Peak's, that number describes the enclosure around your body while your head sits in room air, which is a different session than a 150°F enclosed cabin. Treat the two temperature figures as describing two different environments rather than as one unit being simply hotter.
What $5,450 buys: the Peak Saunas Mini
The Peak Saunas Mini is a one-person, seated, full-spectrum cabin in Canadian hemlock, 31 inches wide, 32 inches deep, and 67 inches tall, which puts it at about 7 square feet of floor and a foot under a standard 80-inch doorway. Eight heating panels combine carbon far-infrared with halogen and quartz emitters for near and mid coverage, which Peak describes as 700 to 25,000 nm, reaching a stated 150°F. It plugs into a standard 120V/15A outlet (NEMA 5-15P), the lightest electrical requirement in our cabin coverage.
The red light panel is the part of the spec sheet worth reading twice. Peak publishes a 9 by 12.6 inch front-wall panel with dual-chip LEDs, a 30-degree beam angle, eight wavelengths (630, 650, 660, 670, 810, 830, 850, and 1060 nm), and stated irradiance of 175 mW/cm2 at 6 inches, 107 at 12 inches, and 80 at 24 inches. Peak values the panel at $1,299 on its own. These are manufacturer figures, not third-party measurements, but they are complete enough to line up against standalone red light panels on paper, which integrated sauna red light almost never allows.
The rest of the build: interior and exterior touchscreens plus a WiFi app for iOS and Android, two 6-inch Bluetooth speakers, chromotherapy lighting, an oxygen-ionization air mode, and a foot-reflexology heater. Assembly is clasp-together, about an hour with two adults per Peak. The warranty is described as lifetime with lifetime US-based support, which we report as the brand states it since no term lengths are published. Delivery is free in the continental US, crated, in one to two weeks. Our desk review scores it 8.2. For the brand's full lineup, see the Peak Saunas hub or our Peak Saunas review, which sets the Mini against the two-person Fuji.
Where the Peak Mini gives ground
It is one seated person, full stop; there is no second seat and no stretching out. The 150°F stated ceiling is modest for a cabin. Peak is a young direct-to-consumer brand, and the Mini was first listed on 2026-06-23, so there is no long-term reliability record and no independent review of this specific model yet. EMF is described as ultra-low without a published figure or third-party test. The $7,295 compare-at is Peak's own anchor: the observed price was $5,950 at launch and $5,450 at our 2026-08-17 check, so read any discount against those numbers, not the anchor. The cabin's shipped or assembled weight is not in our verified data. And once it is built, it stays built; portability is zero.
Heat and spectrum: two full-spectrum claims, two different rooms
Both brands describe their units as full spectrum. Therasage does it with three full-spectrum panels and two red and near-infrared panels; Peak does it with eight panels mixing carbon far-infrared with halogen and quartz near and mid emitters. Neither publishes an independent spectral measurement in our data, so on emitter type the honest comparison is this: Peak has more panels and a stated wavelength range, and Therasage has a stated 98% emissivity and a higher stated ceiling of 170°F against Peak's 150°F.
The bigger difference is the room. In the Therasage your torso and legs sit inside a fabric enclosure and your head is out in ambient air. In the Peak you sit inside a closed hemlock cabin, head included. If you have used both formats you already know which one you want. If you have not, the head-out design is the thing most likely to surprise a first-time buyer, in either direction, and it is worth trying a tent sauna somewhere before you rule it in or out.
Power and footprint: both plug in, only one folds
Neither needs an electrician. The Therasage draws 900W from a standard 110V outlet, and its 220V variant sells at the same price for 220V regions. The Peak runs on a 120V/15A outlet, which is a lighter requirement than the 20A circuits some plug-in two-person cabins call for. That is a real point in the Peak's favor among cabins, and a non-issue for the tent.
Footprint is the decider. The Therasage stands 33 by 33 by 46 inches set up and folds into a bag at 24 lb, so it can live in a closet, a car trunk, or a hotel room. The Peak occupies about 7 square feet at 31 by 32 inches, stands 67 inches tall, and arrives in a crate for a roughly one-hour, two-adult assembly. It fits corners and low-ceiling rooms that exclude every two-person cabin, but it does not move again without taking it apart.
Red light: two panels versus a published spec sheet
If integrated red light is part of why you are shopping, this section decides it. The Peak Mini's panel comes with the numbers a red light buyer asks for: eight wavelengths from 630 to 1060 nm, a 30-degree beam, and stated irradiance at three distances, on a panel Peak prices at $1,299 separately. The Therasage includes two red and near-infrared panels, and that is where our verified data stops; no wavelengths, no irradiance, no beam angle. Both sets of claims are brand-published. The difference is that one brand published enough to be checked and compared, and the other did not.
Price: a $4,022 gap, and what closes it
At list, the Peak Mini costs $4,022 more than the Therasage. Apply LIFESPANVAULT and the Therasage lands near $1,285, widening the gap to about $4,165. Neither carries a subscription or a recurring fee. The Peak ships free and crated in the continental US; Therasage's shipping cost is not in our verified data. What the extra money buys is specific and listable: a wooden enclosure you sit inside, eight panels instead of five, a spec-published red light panel, touchscreens and an app, speakers, and a brand-stated lifetime warranty. What it does not buy is portability, a higher stated temperature, or a track record, since the Mini is a few months old. If those last three matter more to you than the first six, the cheaper unit is the better purchase, not the compromise.
Verdicts by buyer type
- You rent, move, or travel: the Therasage Thera360 Plus. 24 lb, folds into a bag, 900W on any outlet, and about $1,285 with LIFESPANVAULT. Nothing in this comparison touches it on portability.
- You are testing whether the sauna habit will stick: the Therasage. Proving three sessions a week at about $1,285 before spending $5,450 is the rational order of operations, and the tent keeps its use afterward as the travel unit.
- You have a permanent corner and want head-in cabin heat: the Peak Saunas Mini. Hemlock, 8 panels, 150°F stated, on a 15A plug, in a footprint that clears a doorway with a foot to spare.
- You want infrared plus red light you can compare on paper: the Peak Mini. Eight published wavelengths and 175 mW/cm2 stated at 6 inches, versus two panels with no published figures on the Therasage.
- You want a published EMF figure or third-party measurements: neither, yet. Both brands describe low-EMF construction without a number in our verified data, and no independent measurement of either unit exists in our data. See the best 1-person saunas guide for the wider single-seat field.
- You want the brand context first: our Is Therasage worth it piece covers the whole Therasage catalog, and the Peak Saunas review covers the Mini against the Fuji.
Bottom line
The Therasage Thera360 Plus at $1,428, or about $1,285 with LIFESPANVAULT, is the pick for anyone whose living situation, travel schedule, or uncertainty about the habit makes a permanent cabin a bad bet. The Peak Saunas Mini at $5,450 is the pick for a solo user with a permanent corner who wants an enclosed head-in cabin and a red light panel whose specs are on paper. The $4,022 between them buys a wooden room and a spec sheet, not a hotter stated session or a longer track record. Decide on format first, head out or head in, and the price question mostly answers itself.
Which gets hotter, the Therasage Thera360 Plus or the Peak Saunas Mini?
On paper the Therasage, which the brand rates adjustable from 100°F to 170°F in 5-degree steps, against the stated 150°F ceiling Peak gives the Mini. Both figures are brand-stated. The Therasage number describes a fabric enclosure with your head outside it, while the Peak number describes a closed hemlock cabin you sit inside, so they describe two different sessions rather than one simply hotter unit.
Do the Thera360 Plus or the Peak Mini need an electrician or a special outlet?
No. The Thera360 Plus draws 900W from a standard 110V to 120V household outlet, with a 220V variant sold at the same $1,428 for 220V regions. The Peak Mini runs on a standard 120V/15A outlet (NEMA 5-15P), a lighter requirement than the 20A circuits many plug-in two-person cabins specify. Neither needs a dedicated circuit or an electrician.
How much space does each one-person sauna take up?
The Therasage Thera360 Plus sets up at 33 by 33 by 46 inches, then folds into its carry bag at 24 lb, so it stores in a closet between sessions. The Peak Saunas Mini is a fixed cabin at 31 inches wide, 32 inches deep, and 67 inches tall, about 7 square feet of floor, and it clears a standard 80-inch doorway with a foot to spare.
How much does the LIFESPANVAULT code save on the Therasage Thera360 Plus?
Ten percent. The Thera360 Plus lists at $1,428 (verified 2026-08-24), and code LIFESPANVAULT at checkout takes about $143 off, netting roughly $1,285. It works on any Therasage product. It is a partner code we hold rather than a merchant sale, so the site shows full list price until the code is applied in the cart.
Does the Therasage Thera360 Plus include red light like the Peak Mini?
Partly. The Thera360 Plus includes two red and near-infrared panels alongside three full-spectrum panels, but no wavelengths, irradiance, or beam angle are in our verified data. The Peak Mini publishes all three for its 9 by 12.6 inch front-wall panel: eight wavelengths from 630 to 1060 nm, a 30-degree beam, and 175 mW/cm2 stated at 6 inches. Both are brand figures.
