Description

This alder lumber comes milled to a 2x2 nominal profile — finished to 28mm × 36mm — with smooth faces on all four sides and eased edges (S4SEE). That surface preparation matters in a sauna environment: smooth, splinter-free faces reduce the risk of skin contact irritation on benches, backrests, and trim, while the eased edges eliminate sharp corners that can telegraph through finish work.

Alder is a traditional North American sauna wood valued for its low resin content and relatively low thermal conductivity, meaning it stays comfortable to the touch even when the room is fully up to temperature. We carry this profile in both 1-foot and 10-foot lengths so you can source the right quantity for your project — whether you are filling out a small detail run or framing a full interior.

Key Features

28mm × 36mm finished dimensions — a compact, versatile profile suited to bench supports, trim, and interior framing details
Smooth 4 sides, eased edges (S4SEE) — factory-milled surfaces reduce splinter risk and deliver a clean, ready-to-install finish
Alder species — low resin content keeps the wood from becoming tacky or releasing irritating compounds at sauna temperatures
Low thermal conductivity — alder stays cooler to the touch than denser hardwoods, improving comfort on contact surfaces
Available in 1-foot and 10-foot lengths — lets you match your order closely to the linear footage your project requires, minimizing waste

1'

1-foot (approximately 292 mm) length — practical for short infill runs, patch work, or detailed trim sections where longer boards would create excess offcut waste

10'

10-foot length — suited to continuous runs on benches, backrests, or wall trim where fewer joints mean a cleaner finished appearance

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.

Awesome!

I ordered my heater on a Thursday and it arrived the following Tuesday.
The price was by far the lowest I was able to find. I am super impressed with this company.
