Where We Ship
We currently ship everywhere in the continental United States. We can also ship to Alaska and Hawaii which will incur an extra cost – to get a quote for your order, contact us directly at sales@selectsaunas.com or via our chat or contact page. Unfortunately, we do not ship internationally yet. If for some reason you are unsure whether we can ship to you, please contact us and we will let you know.

Shipping Timeline
Due to the custom nature of some of our saunas, some will take at least 6-8 weeks before they are ready to ship, and this may be extended if the sauna is particularly specialized or customized.
The exceptions to the rule are sauna accessories and prefabricated saunas (such as infrared, for example), If they are in-stock they should be delivered within 14 business days after payment is processed.
Handling, Transit & Cutoff Times
After you place your order, we will process it, confirm stock levels, confirm your shipping address, and get your order ready to be shipped. This means handling times generally take 2-7 days, with orders placed before 2:00 PM. We use FedEx, USPS, and UPS for delivery in the contiguous United States. Transit times range from 3-14 days, usually taking less than a week to get delivered.
If we are experiencing a high volume of orders, shipments may be delayed by a few days. Please allow additional days in transit for delivery. If there will be a significant delay in shipment of your order, we will contact you via email or telephone.
If there is a delay to your order due to unforeseen circumstances, such as extreme weather or unavailability or price change through the supplier, a dedicated customer support specialist will reach out to you using your contact details listed in the order form. We will inform you of what happened, why, and any changes in the item ordered. If the new conditions are unacceptable to you, you have the right to cancel the order at that time.

a. Check if there are any visible signs of damage, such as dents, scratches, or punctures and make sure to note this when signing the delivery receipt. A signed delivery receipt, without notations of damage, represents your acceptance of the complete order in perfect condition. Failure to report the damage may result in delaying or refusing freight claims.
2. Count all the pieces of your package and ensure they’re accounted for.
a. Immediately report any missing pieces within 48 hours by emailing directly at sales@selectsaunas.com or via our contact us page. This 48-hour window is vital as we will not be able to replace missing pieces after this window

Taking Delivery of Your Product
Saunas & Sauna Kits
These products will ship LTL (Less-Than-Truckload) and will be delivered on a pallet. These shipments require a delivery appointment, which the last mile carrier will call to schedule with you. Delivery is curbside only, which means that the carrier will not carry the shipment to your door. In some cases, you can a add door-to-door service with the carrier – simply contact them when scheduling and say that you want to add door-to-door service. Door-to-door (also known as white glove) will be an additional charge, so make sure you ask the carrier what they charge for this service.
Due to the size of some of our larger cabin and barrel saunas, they will ship via a flatbed truck and will not fit on a liftgate. This means that you will be responsible for offloading the sauna. We recommend gathering 3-4 people to offload the sauna piece by piece or renting a forklift. Alternatively, you can add a Driver Offload service at checkout if you would like a hands-off offloading experience.
Here's what taking delivery of your sauna kit can look like:
Heaters & Stoves
These products will generally ship to your door, and do not require a delivery appointment, unless your shipment is very heavy (large stoves with a high stone capacity, for example). In this case, the heater or stove will ship LTL – see above. Otherwise, you will be notified by the carrier via text message when your order has been delivered to your door.
Accessories & Small Shipments
These products will ship to your mailbox or to your door. You will be notified by the carrier via text message when your order has been delivered.
Found a lower price? We'll match it!
We work very hard to ensure that we offer the absolute lowest sauna prices online.
We work with our suppliers to ensure that they set Minimum Advertised Pricing (MAP) guidelines for all of our competitors. This means that everyone else selling the same product online is required to be selling it at the same price or higher. If you find another online store that offers a lower price than us, please contact us and we will make sure they are not breaking the MAP policy. If they are not, we can match their price for you! In that case, we can send you a custom discount, or you could simply purchase and we will refund the price difference.
Our Price Match Guarantee has some limitations:
- The item must be of the same brand and model.
- The item must be in stock on the competitor's website.
- You must be able to document the lower price, for example by showing us a a screenshot and a link to the competitor with the lower price.
- If the competitor is charging for shipping, their shipping cost will be included in the calculation of the price match.
- The competitor must be an online-only store, i.e. they can not have a retail location.
- The website can not be a discounter or auction website.
- The competitor must be an Authorized Retailer of the product in question.
- Promotions such as rebates and "buy one, get one free" offers are not eligible.

So far so good
Was alot of work to put together but instructions were clear for the most part. Some issues around the door installation but was able to eventually figure it out but instructions were not clear even after figuring it out. I wonder if the door seal could be more substantial. There is a challenge getting temp consistant across the unit even with a 9kw heater. Feel as if a lot of heat is lost right at the door. I would recommend this product as it looks great and enjoying having it up and running.

Nice stuff
Harvia WZ115100 Smoke Pipe, Sauna Wood Stove , 1.0m, 115mm, Stainless Steel
Anisa Khandkar
Perfect size sauna, amazing price … THANK YOU!
The sauna took two days to build. Read the instructions carefully. Then read them again. You will be fine putting this together with two able - bodied people. Delivery was curbside-only in my area. Over 1100 lbs total, but no single part in excess of ~ 60 lbs, if I had to guess.
Okay now to the good part: this sauna is GREAT. With the base heater offering (Harvia 80B), it takes about an hour to heat from 65F to 160F. It easily goes up to 200F and that’s when we turn it off. From there it holds over 180 for another 35 - 40 minutes. I love the design. I am 5’5, my husband is 5’8, we both fit comfortably laying down on the top bench (minimal contact). If one of us props up on the backrest, then no contact. There’s about a 30 degree F temp difference from the top to bottom bench. The bottom bench is a great relief when it’s too hot on top and allows a third person to lay flat. We immediately sealed the sauna with oil to give it a protective coat and a lovely cedar smell. I could not be happier!!

Maybe we got lucky but our assembly was easy and only took a few hours. After the electrician set up the electrical we put the rocks in and did some final touches and it was ready to go. The whole process was easier than expected.

Perfect Wood Fired Hot Tub
After looking at several types of wood fired hot tubs we chose the SaunaLife S4N. It is the perfect size. It was easy to assemble and heats up quickly. I love the fiberglass liner. It also includes a cover and steps, which are an extra cost on other models.
We are very satisfied with our hot tub and highly recommend it.

Solid sauna
Nice sauna so far, delivery was smooth and installation was fairly easy. Only needed a second person to hold up the door while attaching a second wall. Sauna itself works well and will get to 120 F in about 15-20 minutes or so. Would be a tight fit for two American sized individuals but wasn't planning for two people anyway. Overall good purchase providing it lasts a while.
