Description

ProSaunas Alder 2x4 Sauna Bench Wood is alder lumber, milled smooth on all four sides with eased edges, which ProSaunas recommends for sauna surfaces and will remain comfortable to the touch even in the extreme heat of a sauna. Each piece is 1.1 in thick and 3.54 in wide and is sold by the piece in lengths from 1 ft to 10 ft.

Why alder for a sauna?

ProSaunas selects alder with a light color and a subtle grain pattern. ProSaunas describes alder as durable and naturally water resistant, with a uniform pore structure and even color, and its low heat conductivity keeps it comfortable to the touch in a hot sauna.

Smooth four sides, eased edges

ProSaunas mills this 2x4 smooth on all four sides (S4S) and eases the edges, softening them for comfort against bare skin. ProSaunas recommends it for sauna surfaces and will remain comfortable to the touch even in the extreme heat of a sauna.

Nominal 2x4 vs. actual size

"2x4" is the nominal size: the piece's size when it is cut from the log, before drying and surfacing. The finished piece is 1.1 in thick and 3.54 in wide.

Matching paneling, bench wood and trim

Most saunas are built in one wood. Alder Sauna Wood collects every Alder paneling profile, bench size and trim piece, so the paneling and trim can be matched to this bench wood. Sauna Bench Wood lists every bench wood profile in all species.

Cleaning and care

ProSaunas recommends wiping benches, walls and floors with a mild detergent solution to remove sweat, oils and dirt, and ventilating the sauna after each use so moisture does not build up and lead to mold or mildew.

Shipping

ProSaunas sauna wood from Topture ships to the 48 contiguous US states at a flat freight rate. Checkout calculates it from two things: how many boards are in the order, counted across all sauna wood in the cart, and the length of the longest board. It appears at checkout as "Insured Shipping": every Topture shipment is insured.

How much does shipping cost for sauna wood?

Freight per order to the contiguous US, by number of boards (rows) and longest board (columns)
Boards	Up to 8 ft	Over 8 ft, up to 10 ft
1–19	$195	$295
20–39	$395	$495
40–99	$495	$595
100–299	$695	$795
300–499	$895	$995
500–799	$995	$1,095
800–999	$1,295	$1,395

The rate is for the whole order, not per board: 30 boards of up to 8 ft ship for $395 in total. One board longer than 8 ft moves the whole order to the right-hand column, so 30 boards of 8 ft plus one 10 ft board ship for $495. If the order also contains other products, their shipping is calculated separately and added at checkout.

Which sauna wood orders are quoted after checkout?

Boards longer than 10 ft, orders of 1,000 boards or more, and deliveries to Alaska, Hawaii, US territories or Canada ship by freight quoted for the delivery address. Topture sends the quote after you order, and it is paid separately.

How is sauna wood delivered?

Boards up to 8 ft: smaller orders usually ship by parcel in cardboard, and larger orders on a pallet by LTL freight with a liftgate.
Boards over 8 ft: on a pallet by LTL freight without a liftgate, so unloading needs a dock or hand offloading at the delivery address. The carrier allows one hour before extra charges apply.
Freight is delivered curbside by appointment.
Some remote addresses don't qualify for the flat rate; Topture confirms any extra charge with you before the order ships.

We thought about buying a sauna for years and finally did. We absolutely love it, especially in the winter. It’s incredibly easy to assemble with two people the whole family uses it.

Verified buyer

Ordered this sauna fall 2024 and we love it. No better feeling during a Minnesota winter. Lastly, I have to mention the customer service for this purchase has been like no other. Any questions or requests I had were addressed immediately by Topture. I got more than I expected from them and have already recommended them to several people looking for saunas. SO if you're thinking about it, JUST DO IT already..

Frequently Asked Questions

What is the ProSaunas Alder 2x4 Sauna Bench Wood used for?

It is milled smooth on all four sides with eased edges for comfort against bare skin, and each piece is 1.1 in thick and 3.54 in wide.

What does "smooth four sides, eased edges" mean on the Alder 2x4 Sauna Bench Wood?

Smooth four sides (S4S) means the ProSaunas Alder 2x4 Sauna Bench Wood is planed smooth on every face, and eased edges means its corners are softened rather than left sharp. ProSaunas uses this profile for sauna benches and similar surfaces because the smooth faces and softened edges are more comfortable against bare skin.

How is the Alder 2x4 Sauna Bench Wood shipped, and what does shipping cost?

The ProSaunas Alder 2x4 Sauna Bench Wood ships to the contiguous US at a flat freight rate that checkout calculates from the number of boards and the length of the longest board: 1–19 boards up to 8 ft ship for $195, 20–39 boards for $395 and 40–99 boards for $495, with higher tiers up to 999 boards.

General Topture Questions

Where are you located, and where do you ship from?

Topture is an online retailer serving customers in the contiguous United States. The company is Topture LLC, a Wyoming limited liability company, and its registered business address is 30 N Gould St, Ste N, Sheridan, WY 82801.

Orders ship from manufacturer and distributor warehouses in the U.S. and Canada, and some products ship directly from the manufacturer in Europe. Each product page shows its estimated delivery time.

How much is shipping?

Orders over $200 ship free within the contiguous United States. Orders under $200 carry a small shipping fee.

Four exceptions: SaunaLife and ThermaSol products carry a freight charge at any order value, ProSaunas sauna wood ships at a flat freight rate set by the number of boards and the longest board, ProSaunas sauna doors and windows ship at a flat rate per order shown on their product page, and sauna stones ordered without a heater ship at $60 per box because of their weight.

Every charge is shown at checkout before you pay.

Do you provide financing?

Absolutely! To view your financing offer, simply select Shop Pay Installments as your payment method at Step 3 of checkout.

You'll need to enter a debit card to receive your offer, but don’t worry—you can still back out before completing the purchase.

How long will it take for my items to arrive?

If your order is in stock, most orders ship within 2–7 business days of purchase. Transit time then depends on the distance from the warehouse and, for freight, on booking a delivery appointment.

For custom, pre-order or made-to-order items, the estimated delivery time frame is listed on the product page. Delivery dates are estimates, so please don't book installation labor until your order has arrived and been inspected.

What happens after I place my order?

As soon as you place your order, you'll receive a confirmation email with your order details—be sure to keep it for your records. Once your order ships, you'll receive another email with tracking information.

For freight deliveries, the carrier will call or text you to schedule an appointment once the shipment reaches their local terminal. Someone needs to be there to inspect the shipment and sign for it. Smaller parcels arrive by UPS or FedEx without an appointment.

Is there a warranty?

Yes. Products purchased through Topture include the applicable manufacturer’s warranty, subject to the manufacturer’s terms. You’ll find the warranty details for each product under the "Warranty" tab on its product page, and we help with troubleshooting and warranty coordination if an issue comes up.
