How to use it in the sauna
- Fill the reservoir with cool water before the Zone goes into the hot room. Never pour boiling water into it.
- Set it on the lower bench, where SaunaLife says it lasts longest; the water keeps its electronics under 140°F.
- Bring it out of the hot room once you no longer need it there, and never submerge it.
- Do not leave it somewhere below freezing while it is switched off.
The reservoir holds about 0.8 gallon. Fill it with ice instead and the Zone keeps drinks cold.
Sound and light
Two side-facing speakers handle the highs and mids, and a 360-degree subwoofer handles the bass, 2 x 10 W plus 20 W at peak. The design also sends sound into the surface underneath, so the bench becomes part of the speaker; the five-mode equalizer adjusts that effect. The lights run red, green, blue, white, alternating or in time with the music, and a bottom light with a twilight sensor comes on as the room gets dark.
Phone, voice and charging
Pair it over Bluetooth 5.0 or plug in through the AUX jack, and charge your phone from its USB port. A built-in microphone lets you answer or dismiss calls, and your phone’s voice assistant works through it. Two Zones link as a true wireless stereo pair. Charge it only with its own 18 V charger; it will not charge from a lower-power adapter.
Need a ladle to go with it? The KOLO Ladle 2 has a black aluminum cup on a bamboo handle.
