What is the Therasage sauna?

The Therasage sauna (Thera360 Plus) is a soft-sided personal sauna you sit inside on a chair with your head out. Instead of heating the air like a traditional sauna, it warms you with infrared panels around your body, which is why it can feel comfortable at lower temperatures. The “Plus” adds two Tri-Lite panels with red and near-infrared light.

How it feels to use

You sit inside, zip up to the neck and let the panels warm you while your head stays in room air, which many people find easier to breathe than a hot cabin. Therasage suggests starting with 15 to 30 minute sessions and building up, with most people using a sauna 3 to 5 times a week; hydrate before and after, and put a towel on the chair and footpad.

Total setup cost with add-ons

The sauna itself is $1,428; optional comfort add-ons bring a complete setup to $1,602.

Item Price Why add it
Thera360 Plus (110V) $1,428 The sauna
Upgraded Bamboo Sauna Chair $80 Sturdier seat for daily sessions
Bamboo Footpad (110V) $79 Spa-like wood feel under your feet
Sauna Collar $15 Keeps heat in around the neck
Full setup $1,602 Code covers the entire order

What is the “Perfectly Imperfect” Thera360 Plus?

It is a brand-new, never-used Thera360 Plus with minor cosmetic marks such as small scuffs or stitching variations; Therasage says performance is identical and each unit passes the same quality control. On the day we checked it was listed at the same $1,428 with about two weeks to ship, so the standard model is the better pick unless the price changes.

Who the Therasage sauna suits

It suits people who want regular sauna sessions in a small space and like the idea of red light in the same session.

  • Great for: apartments, home gyms, renters, anyone who wants to fold the sauna away.
  • Consider a cabin instead if: you want to sit with your head inside the heat or share with a partner.
  • Tip: ask your doctor first if you are pregnant or have a heart condition, and keep sessions comfortable.
