to a friend
Heavy-gauge stainless and a footprint that doesn't budge. Climbs to temperature quickly and the heat off the stones is mellow, never scorching. Shipped well-protected and the delivery update emails were genuinely useful.
Lovely even heat and a generous rock tray. It's a hefty thing, so have a friend handy for placement. The crate arrived on schedule and intact, and support answered my weight question honestly before I bought so I could plan the lift.
No app, no screen, just a reliable hot room every evening. The floor stand makes loading rocks easier on my back too. Communication from the team was prompt and plainspoken from order to doorstep.
Going with the floor-standing FLB let me keep my bench layout exactly as I wanted. Sturdy base, no wobble, and it heats every bit as well as the wall units. Sauna Co.'s rep actually recommended this configuration after I described my small room — good advice I wouldn't have found myself.
What I ordered is what arrived, performing exactly as the listing promised. The radiant warmth is even and the steam is soft. Freight was a touch slow but a quick email got me a clear, honest delivery estimate.
Holds temperature through a long session without fading. Build quality is obvious the moment you uncrate it. The pre-shipment confirmation call was a nice, old-fashioned touch.
From the first session it's been flawless — quick warm-up, gentle heat, dead silent. Sauna Co. kept me informed every step and the heater landed without a mark on it.
