Description
Thermory's STEP cladding in dark thermo alder pairs a deep chocolate brown colour with broad, angular grooves that give sauna walls real depth. The tongue and groove boards are straightforward to install, whether you are lining a whole sauna, creating a feature wall or finishing another interior space. Fitted vertically, the finely repeating profile helps a room feel wider; run horizontally, it makes the space feel taller. Each pack contains four boards at 27 × 64 mm with a 56 mm effective width, in 2100 mm or 2400 mm lengths, and the profile combines well with our other cladding options for contrast.

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
STEP has broad grooves for an angular look and considerable depth. Installed vertically it helps a room feel wider; horizontally, it makes a room feel taller. The texture comes alive on feature walls, where lighting creates contrasting shadows in the wells between the raised sections. STEP can be combined with our other timber profiles for contrast and detail.
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 cladding 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.
Installation & Care
The tongue and groove boards are easy to install and well suited to DIY sauna projects, as well as other interior finishes. An installation and maintenance guide for our sauna wood cladding is available in the Downloads section of this page.
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.
