Description
Thermory's SHP bench boards are the standard choice for sauna seating: a rectangular profile with radiused corners that is stable and comfortable in equal measure. These thermo aspen boards are 28 mm thick and 120 mm wide with an R3 edge, a 3 mm radius on each corner that smooths the board edge; the 28 mm thickness helps prevent warping and twisting over time. The timber itself is heat-treated aspen, honey-brown in colour with a straight, knot-free grain and a pleasant, toasted scent. Boards come four to a pack in 2100 mm and 2400 mm lengths, well suited to DIY benching; for a fully bespoke system, our Bench Fabrication Service builds to order.

Timber
Thermo aspen is created by heat-treating soft timber. The treatment reduces the wood's moisture content, giving it a tough, rot-resistant structure that releases no resin in the heat and humidity of a sauna. It has a honey-brown colouration, a pleasant, toasted scent and a straight, knot-free grain, which makes it an easy timber to keep looking its best.
Profile
SHP is the standard profile for sauna bench boards: rectangular with radiused corners, usually R2, R3 or R4 (a 2 mm, 3 mm or 4 mm radius on each corner). The radius value describes the smoothness of the board edge; these boards are R3. The 28 mm thickness is important in preventing warping and twisting over time.
Quality & Wastage
This thermo aspen is A-grade: durable, knot-free and with a low risk of splintering. We recommend a 15% wastage allowance, which also covers the small risk of damage in transit; our interactive Bench Board Calculator can help estimate quantities. As a natural product, timber shows some colour variation between packs and batches, and general sauna wood grading standards apply.
Benching options
These boards are well suited to DIY bench building. For a fully bespoke bench system built from market-leading materials, ask about our Bench Fabrication Service.
Brand
Thermory AS, founded in Estonia in 1997, is the largest manufacturer of thermally modified wood in the world, known for fully natural, chemical-free heat-treated timber.
Ordering & Delivery
Timber orders travel on a palletised shipping service owing to their size, and may require a kerbside drop or handballing off the vehicle. Costs are calculated at checkout by order size and quantity, and differ between UK Mainland, Highland and Island postcodes. We normally ship lengths up to 2400 mm; beyond that, shipping costs rise significantly. If we stock a longer length than you need, our cutting service can cut a full-length board down for a small fee, with the off-cut added to the pallet. For longer lengths, the cutting service, or advice on sizes and quantities, call +44 (0) 20 8050 2895 or email support@finnmarksauna.com.
