Designer-B 6KW Sauna Heater
Overview
The Designer-B 6KW Sauna Heater puts control right inside your sauna — ideal for installs where an external controller isn't an option. Wall-mounted and finished in stainless steel, it heats rooms from 100–425 cubic feet and holds up to 50 lbs of sauna stones for a rich, even steam.
Built-in "9+1" controls offer a 9-hour time-delay start so your sauna is hot when you are. Controls mount on the bottom-front (standard) or either side. Includes sauna rocks.

I expected the slim profile to mean weaker heat, but it fills my room beautifully and the stones hold warmth long after. The finish is genuinely handsome. Arrived a day early, perfectly packed.
It actually looks like a design object on the wall, and it heats like a workhorse. Couldn't ask for more. Communication from order to doorstep was excellent.
Up to temperature in about half an hour and silent the whole time. The modern look fits my contemporary build perfectly. Sauna Co. shipped fast and kept me posted.
I paired this with a SaunaLife X2 for my basement and as a total beginner I was nervous about getting it right. The Designer 6kW looks sharp against the cedar and heats my indoor room evenly and quietly. What sealed it was Sauna Co.'s patience — they helped me match the heater to the room size and arranged both items to land together. Genuinely kind people.
Perfect for my smaller room where wall space was tight. The heat is even and gentle, never harsh. Tracking was accurate and a follow-up note checked everything arrived safely.
Elegant, efficient, and dead reliable through two months of near-daily use. The rocks throw a fine steam. The purchase felt personal thanks to clear, prompt replies whenever I had a question.
Heats fast and looks the part. As with any 6kW unit you'll want proper electrical service, which the listing did note. Their support confirmed the breaker rating when I emailed, so install day went without a hitch.
No complaints on heat or build. Just have help on hand for placement. The crate was sturdy and the delivery window text was accurate to the hour.
