Description

This alder trim is milled to a 1x1 profile (21mm × 21mm) with smooth faces on all four sides and eased edges — a finish designation known as S4SEE. That milling detail matters inside a sauna: sharp corners trap moisture and can splinter over time, while eased edges shed water cleanly and feel comfortable against bare skin.

Alder is a traditional choice for sauna interiors because it stays relatively cool to the touch even in high heat, accepts the humid environment without excessive movement, and presents a fine, even grain that finishes consistently. This trim is available in lengths from 1 foot through 8 feet, letting you match pieces to your specific framing or casing needs without unnecessary waste.

Key Features

• 1x1 nominal profile milled to 21mm × 21mm actual — consistent sizing makes it straightforward to plan reveals and alignments before you cut.
• S4SEE milling (smooth four sides, eased edges) removes sharp corners that can splinter in a humid heat environment and feel rough against skin.
• Alder species performs well in sauna conditions — it stays cooler than denser hardwoods and resists the surface checking that high heat cycling can cause.
• Available in eight lengths (1 ft through 8 ft) so you can select the stock closest to your cut list and reduce off-cut waste on the job.

1'

• 292mm length — useful for short casing returns, inside corners, and fill pieces

2'

• Suited to narrow panel borders and short header runs

3'

• Common choice for door casing legs on compact sauna openings

4'

• Covers a standard bench-height run in a single unjointed piece

5'

• Spans most wall-panel widths without a seam

6'

• Matches a typical interior door height for continuous casing legs

7'

• Covers ceiling-height trim runs in rooms with 7 ft ceilings without a joint

8'

• Full 8 ft length minimises joints on tall walls and maximises yield per piece

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.
