Clear answers to help you get the
most
out of your Sauna
Plunge Infrared is indoor only. If you’re building an outdoor sauna setup, Plunge Traditional Sauna is the better fit.
Both deliver the same full-spectrum infrared experience — the difference comes down to heat, speed, and power. Standard reaches up to 160°F and runs on a common 120V outlet, making it the easy-install choice for most homes. Pro climbs to 175°F, heats up faster, runs on 240V, and can add the optional red light therapy panel. Want maximum heat and red light? Go Pro. Want the simplest setup? Standard is your sauna.
Up to 175°F.
The Infrared Sauna Pro runs on a 240V 20A outlet.
Approximately 1 hour.

Yes. The Plunge app lets you set your temperature, start a session, and schedule heat-ups in advance — so your sauna is hot and ready the moment you are. No standing around waiting for it to warm up.
Yes — it just works differently. A traditional sauna heats the air around you; infrared uses light to warm your body more directly. The result is a deep, satisfying sweat at lower room temperatures, which makes infrared especially comfortable and practical for indoor home use.
An optional upgrade on the Pro model, built right into the sauna door. It delivers seven therapeutic wavelengths of red and near-infrared light (480, 630, 660, 810, 830, 850, and 1060 nm) and is engineered to perform in high heat — so you get red light and infrared in a single session.
Yes. The panel lifts out of the sauna door and works as a standalone red light therapy device. It comes with a door-hanging hook for easy use anywhere in your home, and you can add an optional floor stand if you'd rather set it up freestanding. So you get red light during your sauna sessions — and targeted therapy on its own, whenever you want it.
Yes. Premium Nakamichi Bluetooth speakers come built in, engineered to handle the heat. Pair your phone and fill the cabin with your favorite playlist, podcast, or guided session.

"Lucky to test out the new Plunge All-In. I am now, without a doubt, completely spoiled and will never be able to plunge any other way."
