Description
The STS4 profile is a durable alder cladding for sauna walls and ceilings, named for the 4 mm gap between fitted boards. Its slender, angular grooves create a symmetrical, strong aesthetic that has made it a popular choice for modern and contemporary saunas, and it can be used alongside other wood profiles for a distinctive finish. Each board is 15 mm thick and 120 mm wide, with an effective width of 110 mm once fitted, and packs contain six boards in a choice of 2100 mm or 2400 mm lengths. Alder is a popular timber for traditional saunas, light brown with warm pink undertones, and it stays comfortable to the touch in high heat while resisting twisting and warping. The profile also works well beyond the sauna wherever a clean-lined timber wall is wanted.

Timber
Alder is a popular choice in traditional saunas thanks to its natural qualities and low risk of twisting and warping. It has a light brown colour with warm pink undertones, and a subtle scent that resembles freshly cut hay, which many find pleasant in the sauna. Alder does not overheat and has water-repellent properties, so it performs well in hot and humid environments. As a natural product, the timber shows some colour variation between packs and batches.
Profile
The STS4 profile gets its name from the 4 mm gap between each board. Its slim, angular grooves give a symmetrical, strong aesthetic, which has made it a popular choice in contemporary saunas. STS4 boards can be combined with other cladding profiles to create a unique, modern look in the sauna or in other interiors.
Quality & Wastage
Our alder sauna timber is A-grade: durable, knot free and with a low risk of splintering. We recommend a wastage allowance of 15%, which also covers the small risk of damage in transit. General sauna wood grading standards apply to this timber. Contact us if you are unsure how much you need for your sauna build.
Installation & Care
The boards are straightforward to fit and well suited to a DIY sauna build. An Installation and Maintenance Guide is available under the Downloadable Files tab on this page. We recommend treating the wood with paraffin oil, which slightly deepens its colour. Lifestyle images are representational only; the finished look will vary with the width and placement of the cladding.
Ordering & Delivery
Timber orders are shipped on a palletised service due to their size, and may require a kerbside drop. Shipping costs are calculated at checkout and vary between UK Mainland, Highland and Island postcodes. We usually ship lengths of up to 2400 mm; longer lengths cost significantly more to send. If we stock a longer board than you need, our cutting service can cut it to your required length for a small fee, with the off-cut added to the pallet. For longer lengths or the cutting service, contact our team on +44 (0) 20 8050 2895 or support@finnmarksauna.com.
