Description
Thermory's dark thermo alder bench boards bring a deep chocolate brown colour and a strong, toasted scent to the sauna bench. That character comes from intense, fully natural thermal modification, which makes this a premium timber: durable, stable and easy to keep clean. Each pack contains four boards in the SHP profile, 27 × 115 mm with smoothly radiused R3 corners, in a choice of 1800 mm, 2100 mm or 2400 mm lengths. The boards are well suited to a DIY bench build, or our bench fabrication service can craft them into a complete sauna bench system.

Timber
Dark thermo alder has a striking dark chocolate brown colour and a strong, toasted scent, the result of intense, fully natural thermal modification. It is a premium timber: elegant, easy to keep clean and well suited to saunas with a contemporary look. As a natural product, timber shows some colour variation between packs and batches.
Profile
SHP is the standard profile for sauna bench boards: a rectangular section with radiused corners, usually R2, R3 or R4 (a 2 mm, 3 mm or 4 mm radius on each edge). These boards are finished with an R3 edge. The 27 mm thickness is important, helping to prevent warping and twisting over time.
Quality & Wastage
Our dark thermo alder timber is A-grade: durable, knot free and with a low risk of splintering. We recommend a wastage allowance of 20–25% for these bench boards, which also covers the risk of damage in transit. Our wastage allowance guide and interactive calculator on finnmarksauna.com will help you work out quantities. The general sauna wood grading standards apply; grading rules for each timber type are published on finnmarksauna.com.
Bench Fabrication
These boards suit DIY bench building. Alternatively, our sauna bench fabrication service can design and build your ideal bench system from them.
Brand
Thermory, founded in Estonia in 1997, is the world's largest manufacturer of thermally modified wood. Its fully natural, chemical-free thermal modification sits alongside a wide selection of untreated sauna timber.
Ordering & Delivery
Timber orders travel on a palletised shipping service and may require a kerbside drop. We normally ship lengths of up to 2400 mm. If you need a shorter length than we stock, our cutting service can cut a longer board down for a small fee; the off-cut is added to the pallet. For longer lengths, the cutting service or advice on quantities, contact support@finnmarksauna.com or call +44 (0) 20 8050 2895.
