Room to stretch out, share, and unwind.

The Finnleo Sentinel 3 is a roomy three-person infrared sauna that still installs like an appliance. It runs on a standard 120V household circuit, needs no special wiring or plumbing, and fits along a wall in a basement, home gym, bonus room, or primary suite. At more than six feet wide, there's space for the whole family, or for one person to really spread out.

Warmth from every angle. Wall-to-wall far infrared panels are joined by an in-bench emitter, calf emitters, and a floor emitter, so heat surrounds you rather than coming from one side. Finnleo's Pure Infra™ emitters are engineered for low EMR/EF output, so you can relax without worrying about what's in the air around you.

Beautiful inside and out. The cabinet is crafted from smooth, light-toned Okoume wood, and the all-glass front wall gives the sauna an open, airy feel instead of a boxed-in one. Six-color LED chromotherapy lighting along the walls, bench, and exterior entry floor lets you set the mood, whether that's a bright morning session or a calm evening wind-down.

Easy to control, easy to enjoy. The SaunaLogic2®-IR control panel and companion app put temperature, timing, and lighting at your fingertips, and you can preheat before you even walk in the room. Built-in Bluetooth® speakers let you stream your favorite playlist, podcast, or guided meditation.

Simple assembly. Finnleo's pin-and-hook wall locking system makes setup straightforward, and every Sentinel 3 is backed by a 5-year warranty on the IR emitters, wood cabinet, and controls.
