Quick Answer: Smartmak sells two very different products under one name: a Portable Far Infrared Tent at $198.99 (140°F max, 110V outlet, ships flat and folds away) and the Refresh 2 full-spectrum wood sauna room at $3,999 (2-person Canadian Hemlock cabin, 120°F in about 15 minutes, per Smartmak’s own 2026 pricing). Most first-time buyers should start with the tent — it’s the cheapest way to try infrared heat on a nightly basis before committing to a full cabin. Buyers with the floor space and budget for a real 2-person room should go straight to the Refresh 2.

Unlike JNH Lifestyles or Sun Home, which sell tiered wood cabins at every price point, Smartmak’s catalog is really two separate product categories: a budget portable tent that made it one of Amazon’s best-selling infrared saunas, and a pricier full-spectrum wood room sold mostly direct. Here’s how the two compare and which one actually fits your situation.

1. Portable Far Infrared Tent — Best Budget Pick

Smartmak Portable Far Infrared Sauna Tent

Best budget · $198.99 · 1 person
  • Cotton exterior with a waterproof interior lining, folds down to store flat when not in use, and weighs about 27.5 lbs.
  • Runs on a standard 110V outlet, hits its 140°F ceiling in roughly 20 minutes per Garage Gym Reviews' testing.
  • Includes a foldable chair, heated foot pad, remote control, and built-in timer — head and arms stay outside the tent through an arm-pocket cutout.

Sauna time is story time — start a free Audible trial and get your first audiobook free. A 20-minute infrared session is exactly the kind of downtime that pairs well with an audiobook chapter, and the tent’s seated, hands-free design makes it easier to actually listen than a cabin where you’re more likely to be adjusting settings.

2. Refresh 2 Wood Room — Best Full-Spectrum Pick

Smartmak Refresh 2 Full-Spectrum Infrared Sauna Room

Best full-spectrum · $3,999 · 2 people
  • Canadian Hemlock cabin with full-spectrum heaters — near- plus far-infrared — reaching 120°F in about 15 minutes, per Smartmak's own spec sheet.
  • Adds an oxygen ion generator, Bluetooth speakers, and 7-color mood lighting, none of which the portable tent includes.
  • The HARVIA heater carries a 1-year warranty, but Smartmak states its warranty "only applies to saunas purchased directly from Smartmakshop.com" — worth confirming coverage before buying a Refresh 2 through an Amazon third-party listing.

At $3,999 the Refresh 2 lands below JNH Lifestyles’ comparable Tosi 2-Person Cedar ($5,199) and Sun Home’s Equinox 2-Person ($6,099), making it one of the cheaper full-spectrum 2-person rooms in our best full spectrum infrared sauna roundup — though neither JNH nor Sun Home restricts warranty coverage by sales channel the way Smartmak does.

How the tent and wood room actually compare

The choice here isn’t really about picking a “best” Smartmak model — it’s about deciding which product category you need. The Portable Tent at $198.99 is a low-commitment way to build a daily infrared habit in an apartment or rental where a permanent cabin isn’t practical; its 140°F ceiling and seated-only design are real tradeoffs, but at one-twentieth the price of the wood room, it’s a reasonable way to test whether infrared heat is worth the routine before spending four figures. The Refresh 2 at $3,999 is a genuine 2-person cabin with full-spectrum coverage and a faster heat-up, but it needs floor space, a dedicated purchase from Smartmak’s own site to keep the warranty intact, and a much larger budget.

The bottom line

First-time buyers and anyone short on space should start with the Portable Tent at $198.99 — it’s the cheapest legitimate way into infrared heat therapy on this site. Buyers who want real 2-person capacity, full-spectrum wavelength coverage, and a faster heat-up should go straight to the Refresh 2 at $3,999, but buy it direct from Smartmakshop.com rather than a third-party Amazon listing to keep the 1-year heater warranty valid.
