Product description

Alder Sauna Wood Cladding STP 90mm by Thermory (Pack of 6) 


Alder Sauna Wood Cladding (STP)


Our Thermory STP sauna wood cladding is a refined choice for the walls and ceiling of your sauna. The easy to install tongue and groove cladding is also suitable for other interior finishes. The STP profile has narrow grooves and rounded edges that create a soft finish once installed. The grooves behind each panel allow condensed steam to run down and drain to the floor. The STP cladding can be used with other sauna wood profiles to create contrast in the space for a unique finish.   


The STP tongue and groove cladding are great for fitting in a DIY sauna.   


About our Alder Sauna Wood Cladding 


Alder is a popular wood choice in traditional saunas because of its natural qualities and a low risk of twisting and warping. Alder has a beautiful light brown colour with warm pink undertones. The subtle scent resembles that of freshly cut hay that many find pleasant in the sauna. Alder does not overheat and has water repellent properties, making it suitable to be used in hot and humid environments.

Information on our STP Profile 


Choosing sauna panels is all about your personal preference and we have styles to fit the atmosphere and interior specs you wish to create. The STP profile offers an elegant wall surface for your sauna, with narrow gaps between each cladding board. STP’s rounded front edges can have a “softer” appearance than Kallio or STS4 cladding. Like all our cladding profiles, STP boards can be combined with other options to achieve your own unique look.

Wastage Allowance for Alder Cladding  


Our alder sauna timber is of A-grade quality, characterised by their durable, knot- free and low risk of splintering properties. As such, we recommend a wastage allowance of 15% for our alder wood sauna cladding. This also takes into account any potential risk of damage that can occur during transportation.

Shipping Information on Sauna Timber 


Depending on the size and quantity of your sauna timber order, the shipping costs may vary and will be calculated at checkout. Shipping costs also differ between UK Mainland, Highland and Island postcodes. Many of our timber products will be shipped using a palletised shipping service due to their big and bulky nature and may require a kerbside drop or handballing off the freight vehicles. Please take time to read our Shipping and Delivery Information carefully before placing an order for our alder cladding. 
Please note that due to certain constraints of our shipping networks, we usually ship timbers of up to 2400m lengths, beyond those lengths the costs for shipping will increase quite significantly. If you do require longer timber lengths, our shipping calculator will indicate associated costs for such shipping. 

If we do not have your required length, but have a longer length available, to avoid higher shipping rates, it is worth considering our cutting service. You will still need to purchase the full length, but for a small fee, we can cut this down to your desired length to help reduce shipping costs. The off-cut will be added onto the pallet. 
For longer lengths or our cutting service, please call or email our Customer Service Team who will be happy to arrange alternatives (+44 (0) 20 8050 2895 or
