Delivery Day: What to Expect

Redwood Outdoors saunas and cold plunge tubs are shipped using freight delivery to ensure safe, secure transport from our warehouse to your home. Below is everything you need to know about shipping and what to expect on your delivery day.

How Redwood Outdoors Products are Shipped

Our saunas and cold plunge tubs are shipped in durable wooden crates designed to protect the product during transit. 

With the shipment of a sauna, the heater, rocks and accessories will either arrive in a box strapped to the top of your crate or arrive separately.

We partner with multiple trusted freight carriers to ensure your order arrives safely and efficiently at your curbside.

Once your shipment leaves our warehouse, you’ll receive an email with a tracking number and link to follow your delivery.

If you’ve ordered multiple large products—such as a sauna and a cold plunge—they may arrive in separate shipments. 

Freight Delivery

Our shipments are delivered by a large freight truck, typically equipped with a liftgate. This allows the carrier to lower the crate to ground level upon arrival. 

If your delivery location has limited access for large trucks—such as steep, unpaved, gated, or restricted roads—please contact our customer service team before shipment so we can review access requirements and help you prepare.

Delivery Day

Your shipment is on the way, here's how to prepare.

Once your order arrives at the carrier’s local depot, they will contact you to schedule a delivery appointment.

Appointments are typically scheduled within 2–3 business days of arrival at the depot. 
Please ensure that someone is available to receive and sign for the delivery when it arrives at your home.
- If your heater is shipped separately, a signature will be required for that shipment as well.

All freight shipments are curbside delivery, meaning the crate is placed at the end of your driveway or nearest accessible location. 

For liability reasons, freight carriers are unable to move shipments beyond the curb or into backyards, garages, or other areas of the property.  If you need help relocating your crate after delivery, we recommend arranging assistance in advance.

Choose the Right Location
