Description

Aspen Midnight Black 1x4 nickel-gap tongue-and-groove paneling brings a deep, dramatic finish to sauna walls and ceilings. The blackened aspen retains the wood's natural grain character while shifting the visual tone from traditional pale blonde to a rich, matte dark surface — a look that pairs well with both modern and rustic sauna interiors.

At 15mm x 90mm (nominal 1x4), each board offers a sturdy profile without adding unnecessary bulk to your wall assembly. The nickel-gap profile creates a consistent, narrow reveal between boards as they interlock, producing clean shadow lines that add depth and visual rhythm to the finished surface. The tongue-and-groove joinery keeps edges aligned and the installation tight.

Key Features

• Blackened aspen finish — the dark treatment works with aspen's natural grain to create a matte, contemporary aesthetic without concealing the wood's character.
• 15mm x 90mm profile (nominal 1x4) — this thickness provides a solid, stable panel that holds fasteners well and resists warping through sauna heat cycles.
• Nickel-gap tongue-and-groove joinery — boards interlock precisely while leaving a narrow reveal between each course, adding subtle shadow lines and allowing for natural wood movement.
• Available in lengths from 1 ft to 10 ft — having multiple length options lets you minimize waste and match your specific wall or ceiling run without unnecessary cuts.

1'

• 292mm finished length — suited for accent sections, borders, or areas with tight horizontal spans

2'

• Short-run length useful for framed sections and feature walls with limited span

3'

• Mid-short length that works well for lower bench walls and partitioned areas

4'

• Common length for smaller sauna enclosures where full-length boards would require significant trimming

5'

• Versatile mid-length suited to compact to mid-size sauna wall runs

6'

• Covers standard ceiling heights in a single board run, reducing seams on vertical installations

7'

• Accommodates taller sauna walls or angled ceiling runs without piecing together shorter boards

8'

• Full 8 ft run spans typical wall heights end-to-end, keeping seam count low for a cleaner finished surface

9'

• Extended length for longer horizontal runs or oversized sauna interiors where fewer joints are preferred

10'

• Maximum available length — minimizes the number of boards and seams across long uninterrupted wall or ceiling spans

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.
