We know your dream sauna or cold plunge kit is a big purchase. That’s why we partnered with Affirm to finance your purchase with interest rates as low as 0% APR.
Rates from 0–36% APR. For example, a $6500 purchase might cost $271/mo over 24 months at 0% APR. Payment options through Affirm are subject to an eligibility check and are provided by these lending partners: affirm.com/lenders. Options depend on your purchase amount, and a down payment may be required. See affirm.com/licenses for important info on state licenses and notifications.
Use Your HSA/ FSA Funds to Purchase a Sauna
Unlock the potential of your HSA/FSA funds with Redwood Outdoors! To further support your investment in health and relaxation, we’ve partnered with TrueMed to make it easier for you to use your Health Savings Account (HSA) or Flexible Spending Account (FSA) funds for your purchases.
Please double-check your shipping address at checkout—any errors may result in re-routing fees.
Once your order ships, you'll receive two tracking links to monitor its journey: one for transit to the local depot and another for final curbside delivery.
All freight orders include an “appointment required” service. Carriers will typically call ahead to schedule delivery, though some may call when already en route. If you’re unavailable at that time, you may reschedule—just note that missed deliveries without prior arrangement can result in extra fees.
Delivery timelines are estimates and may be affected by weather, carrier delays, or other unforeseen events. Shipping rates may vary over time, but you’ll always see the full cost before placing your order.
Any adult at the delivery address is considered authorized to accept the shipment.
