Silky Smooth Aspen for Your Sauna Bench

Crafted from premium, straight-grained Aspen, this 68 × 68 mm bench material delivers a satin-smooth surface that feels genuinely comfortable against bare skin. The S4SEE profile — smooth on all four sides with softened, eased edges — means no sharp corners, no splinters, just a refined finish that invites you to sit back and relax.

A Natural Choice for Sauna Environments

Aspen is prized as a sauna material for good reason: it does not secrete resin, does not splinter, and its low heat conductivity keeps it comfortable to the touch even in the intense heat of a sauna. Its very good dimensional stability and resistance to splitting make it equally well suited for benches and floors alike.

Light, Elegant, and Built to Prosaunas Standards

Aspen's characteristic light, creamy tone and uniform texture give any sauna a clean, contemporary look — and its smooth surface takes paint beautifully if you want to customize the finish. Backed by more than 55 years of sauna craftsmanship, Prosaunas sources only the finest wood from Northern Europe and Canada, so every 292 mm length meets their stringent quality standards before it reaches you.

Description

This Aspen S4SEE profile is milled to a 3x3 nominal dimension (68mm × 68mm actual) with all four sides smooth and edges eased, giving you a clean, splinter-free surface that is well suited to the high-humidity environment of a sauna interior.

Aspen is a traditional Nordic sauna wood chosen for its low resin content, which means it stays cool to the touch on benches and walls even as temperatures climb. The smooth four-sided finish reduces the finishing work required on site and keeps the visual result consistent across every surface it covers.

Key Features

3x3 nominal profile, 68mm × 68mm actual — a substantial thickness that resists warping across the humidity and temperature cycles typical in sauna use
Smooth 4 Sides Eased Edges (S4SEE) mill finish — all faces are planed and edges are slightly relieved so installation is clean and the assembled surface is comfortable against skin
Aspen species — naturally low in resin and tannins, so the wood will not exude sticky pitch or leave dark staining on contact at sauna temperatures
Available in 1-foot and 8-foot lengths — allowing you to plan cuts efficiently and minimise waste for your specific wall, ceiling, or bench layout

1'

1-foot (292mm) length — useful for filling short runs, trimming around vents or fixtures, and reducing offcut waste in tightly dimensioned spaces

8'

8-foot length — covers standard wall and ceiling runs with fewer end joints, keeping the finished surface visually consistent

SHIPPING & DELIVERY

Sauna wood is not free shipping. Length, piece count, profile, and weight set the rate. These are the Bathing Brands contiguous-US flat rates. Canada is the same table plus $100. Alaska, Hawaii, and remote addresses are quoted.

Checkout charges the 8' piece-count table (contiguous US). Canada is the same table plus $100. Boards over 8' use that same checkout rate; dock or liftgate extras are a follow-up. Alaska, Hawaii, and remote addresses are quoted.

BOARDS UP TO 8'

Under 40 pieces generally ships FedEx Ground in cardboard. Over 40 pieces generally ships LTL with a liftgate on a wood pallet. The longest board in the order sets the rate tier.

Under 19 boards — $195
20–39 boards — $395
40–99 boards — $495
100–299 boards — $695
300–499 boards — $895
500–799 boards — $995
800–999 boards — $1,295

BOARDS OVER 8' UP TO 10'

These lengths ship LTL on a wood pallet. They do not qualify for a liftgate — you need a dock, machinery, or hand offload on site. Carriers allow about one hour to unload before extra fees.

Under 19 boards — $295
20–39 boards — $495
40–99 boards — $595
100–299 boards — $795
300–499 boards — $995
500–799 boards — $1,095
800–999 boards — $1,395

HOW THIS SHIPS

We pack for a safe arrival at the lowest rate that fits the order.
Boards over 8' carry a surcharge because long crates cost more to move than a standard skid.
Heaters, doors, or accessories on the same order can offset some of that freight.

Great Cold Plunge Tub

This is a great cedar-sided cold plunge tub. I spent a considerable amount of time researching cold plunge tubs and wanted one with real ceder wood to fit my sauna room. It also has a durable heat pump, compared to lower-quality chillers. I have had it a few months and no issues. Also, in the pics below, I have the chiller, which is about a 2' x 2' cube plumbed to a different space for a clean sauna room look. I would highly recommend this tub and the price is less than some on the market.

These guys are AMAZING!

These guys are AMAZING! I’d leave 10 stars if I could. We purchased a barrel sauna and cold plunge from them in fall 2025. They were absolutely terrific to work with! Our contractor and electrician had many (many) questions, all were promptly and kindly answered. They even customized our order by selling an extra long cord so we could install control panel inside for extra protection in MN winters. Shipping and delivery was a breeze. We are using our sauna daily and love it! Zero hesitation recommending this company! Thank you Johnny and Mitch for all your help!!!

Harvia Cilindro Half Series 6kW Sauna Heater

What a wonderful sauna!

Researched many saunas for many months. Finally landed on this one. Only complaints i have are the instructions weren't very well written and the trim on the outside was very difficult to put together. We use it almost daily.

Great service, great sauna

Super stoked about the new sauna. I ended up with a beautiful 2-3 person cedar sauna with a huum heater. It’s perfect. These guys were helpful in choosing the right size, type, etc.
very glad I used the cold plunge guys.
