Finnmark Cedar Combination Barrel Sauna FD-6 - 4 Person
The Ultimate Cedar Sauna Experience — Traditional Heat Meets Advanced Infrared
Step into the world's finest cedar combination barrel sauna, where infrared and traditional unite for an unmatched wellness experience. Reach temperatures up to 185°F, and enjoy the invigorating ritual of pouring water over hot stones for a rich, steamy session—all while enjoying the deep, penetrating warmth of infrared heat. This is sauna enjoyment at its most luxurious.
Every detail of this sauna reflects premium craftsmanship and thoughtful design. Built with thick, 1.5” full-length Canadian Cedar staves, it offers unmatched beauty, durability, and a naturally aromatic ambiance. Dual-level benches and backrests, also crafted from Canadian Cedar, are naturally antimicrobial and satin-smooth, remaining cool to the touch even in high heat.
Stunning Design, Built to Last
An 8 mm-thick tempered glass door and window panels create an open, upscale aesthetic while providing lasting strength. A complete shingle kit ensures your sauna stays dry and protected, no matter the weather.
Get Hot, Fast — Inside and Out
Equipped with Finnmark Spectrum Plus™ Infrared Heaters, this sauna delivers both mid- and far-infrared waves that deliver deep, penetrating warmth, triggering up to 25 times more sweat than standard carbon heaters. Choose your traditional 4.5kW heater for fast, powerful heat and satisfying steam.

Shipping & delivery
Shipping cost: Shipping on this item is free within the contiguous US.
Most in-stock orders ship within 3–5 business days of confirmed payment, and delivery is typically 5–15 business days after shipment. Made-to-order saunas and custom-configured rooms need production time on top of that, which we confirm before the order is released. We ship within the contiguous United States.
Large items ship LTL freight on a pallet, delivered curbside — to the curb or the end of your driveway, often from a trailer up to 53 feet long. Curbside does not include unpacking, assembly, installation or electrical connection. The carrier calls to book an appointment and someone must be there to receive the shipment. Tell us at the time of order if access is limited — narrow or rural roads, steep driveways, gated communities — and ask for liftgate service if you have no dock or forklift.
Inspect the shipment before the driver leaves and before you sign. Count the cartons and pallets against the paperwork, check glass doors and panels, write any damage or shortage on the Delivery Receipt, and photograph it. Email info@plungeintosaunas.com within 48 hours of delivery with your order number, photos and the noted receipt — the same window covers concealed damage and missing items. Keep the packaging while a claim is open.
Cancellations & returns
Cancel before the order has been submitted for fulfillment and it is refunded in full — email info@plungeintosaunas.com with your order number. After that point manufacturer, carrier, return-freight or restocking fees may apply. Every return must be approved by us in writing first: products ship from different manufacturer warehouses, so the correct return address varies, and anything sent back without authorization may be refused.
Return requests are made within 30 days under our general policy; some brands run that window from the date of purchase rather than delivery. Items must be unused, uninstalled, never heated or filled, complete in their original packaging and in resalable condition. Restocking fees run up to 25% depending on the manufacturer, while Harvia, HUUM, SaunaLife, Saunum, Narvi, ThermaSol, Delta, Kohler and Mr. Steam charge no restocking fee at all, only a re-boxing fee of roughly $20–$50 if the original packaging does not come back intact. On a change-of-mind return you pay return shipping and the original outbound shipping is not refunded.
If the item arrived damaged or a manufacturer error is at fault, return shipping is covered for you. Custom, made-to-order and special-order items already in production, clearance and open-box items, heaters that have been wired or fired, tubs and generators that have been filled, assembled or heated rooms, opened consumables and all Canadian Timber Collection products cannot be returned. Ask us before you buy if you are unsure.

Setting up
What happens between checkout and your first session.
-
The FD-6 ships at 1,005 lbs. Curbside delivery by appointment, palletized. The driver's job ends at ground level — they lower the pallet and leave it at the end of your driveway, so line up two people and a clear path to move the pieces from there.

-
What you need at the panel depends on the heater you pair with the room, and on extras like lighting. Electric heaters take a dedicated 240 V circuit sized to their output, with the breaker and wire gauge set by that heater's manual, and final hookup is a licensed electrician's job. Wood-burning stoves need no power at all — just a chimney kit and the clearances the manual specifies.

-
Its footprint is 75" x 79" x 75", so size the base to that and a little beyond. A level, load-bearing base is the part worth getting right: a concrete pad, patio stones over compacted gravel, or a deck rated for the loaded weight all work, as does an interior floor that carries the load. Leave the heater clearances from the manual and room for the door to swing, and check local permit rules before you build.
