Pro D Bluetooth - Black | Harvia
Pro D Bluetooth - Black | Harvia

Forty minutes into a long session, when the heat has settled, and you're not going anywhere for a while, the right playlist makes the difference between a good sauna and a great one. The Harvia Pro D Bluetooth is a wall-mounted sauna amplifier designed for exactly that environment — rated for temperatures up to 100°C and humidity up to 99%, so it lives inside the sauna room where you can actually reach it from the bench. Pair up to three devices simultaneously over a 30-meter Bluetooth 4.0 connection, adjust volume without standing up, and use the built-in microphone to take calls or talk to your voice assistant without touching your phone. The anthracite housing is compact enough to disappear into the wall and matches the design language of Harvia's Pro D control series. External speakers are required and sold separately — pair it with sauna-rated speakers and the sound you get is clean, room-filling, and built to last in conditions that would destroy standard audio equipment. For anyone building a sauna they plan to spend real time in, this is the piece that makes the room feel finished.

Rated for 100°C, built for the sauna interior. IPX4-certified and tested to operate at temperatures up to 100°C with relative humidity up to 99% — this is a genuine sauna-interior unit, not a bathroom speaker mounted near the door.

Three devices, one player. Pair up to three phones or tablets simultaneously over Bluetooth 4.0 with a 30-meter range, so guests can queue music from the bench without passing a phone around or asking anyone to disconnect.

Volume control from the bench. The wall-mounted control panel adjusts volume without requiring you to stand up, step toward the heater, or touch a phone — the point of a sauna is staying on the bench, and this keeps you there.

Integrated microphone, hands-free calls. The built-in mic handles phone calls and voice assistant commands (Siri, Google Assistant) directly, so you can answer a call or set a timer without leaving the room or breaking the session.

High-end amplifier, clean output. The onboard amplifier is designed for crystal-clear audio rather than the distorted, tinny output of consumer moisture-resistant speakers — pair it with quality sauna-rated external speakers for the difference.

Requires external speakers — sold separately. The Pro D is an amplifier and Bluetooth receiver, not a self-contained speaker. Sauna-rated external speakers must be purchased and installed separately. Wiring requires cables rated to at least 150°C.
