Your sauna ships via freight carrier — a more personalized delivery experience than standard parcel shipping, with scheduled appointments and hands-on coordination. Here's what to expect:

1. Pick Up From Warehouse (Days 1-3)

Once your order is placed we request a freight carrier to pick up your sauna from Finnmark's warehouse outside of Chicago. We use all of the major freight carriers, including Saia, Estes Express, Custom Companies and ACF Freight. Pick up usually happens within 1-3 business days.

2. Transit to Your Local Terminal (Days 3-8)

Your sauna travels to the freight terminal closest to you. Once it arrives, the carrier will call you directly to schedule a delivery appointment — your sauna won't be delivered without one. Depending on your location, a last-mile carrier with a smaller truck may handle the final leg. We'll let you know if that's the case.

3. Delivery Day (Days 8-10)

On your scheduled date, the carrier will arrive with your sauna and lower it off the truck via liftgate, placing it at your driveway or as close to your home as your space allows. Free shipping includes curbside delivery.

When your sauna arrives, take a moment to inspect the packaging before signing. If you notice any damage, note it on the delivery receipt and email us photos at info@sunvalleysaunas.com — we'll handle it from there.

Total estimated delivery time: 5–10 business days from order placement, depending on your location. Some deliveries take a little longer.

Not the right fit? Every sauna is backed by our 30-day 110% Money Back Guarantee. If you decide it isn't for you, we'll arrange the pickup and refund 110% of your purchase price. See our Shipping & Returns Policy for the full details.

Questions about delivery? Give us a call or text at 1-855-963-5665 — we're happy to walk you through it.

This Finnmark sauna comes with our comprehensive ten year warranty, which covers workmanship and parts on the entire sauna, including the infrared heaters, wood and electronics and the included Harvia heater, plus reasonable labor where a repair requires it. Coverage starts on your delivery date. It also comes with a ten year Finnmark Designs warranty and an Unlimited Lifetime Warranty on the Spectrum Plus Infrared Heaters.
