Description

Thermo-Aspen bench boards bring the stability and comfort of thermally modified aspen to your sauna build. The heat treatment process drives out moisture and resins, producing a board that stays dimensionally stable in the wet-dry cycles of a sauna environment and remains cool enough to sit on even at high temperatures — two qualities that raw aspen alone cannot reliably deliver.

Each board is milled smooth on all four sides with eased edges, so you get a finished, splinter-free surface straight from the package. At 28mm × 90mm (a true 2×4 profile), these boards provide the seating depth and structural rigidity that bench construction requires. Available in ten lengths from 1 foot through 10 feet, you can cut your material list precisely and minimize waste for benches of virtually any layout.

Key Features

• Thermally modified aspen: the heat treatment process reduces moisture content and stabilizes the wood so it resists warping and cracking through repeated sauna heating cycles.
• Stays cool to the touch at sauna temperatures — a critical property for any surface that will be in direct contact with skin.
• True 28mm × 90mm cross-section provides the thickness and width needed for solid, comfortable bench construction.
• Smooth 4 Sides, Eased Edges (S4SEE) finish means all faces are ready to install without additional sanding, and rounded edges eliminate sharp corners on seating surfaces.
• Ten lengths (1 ft – 10 ft) let you match boards to your bench dimensions, reducing offcuts and keeping the build efficient.

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.
