Give your sauna a classic, natural finish with our 18mm spruce cladding boards. Crafted from premium Finnish spruce, these boards are smooth-planed, durable, and designed to withstand the heat and humidity of regular sauna use. The pale colour and fine grain of spruce create a bright, inviting atmosphere, while the sturdy 18mm thickness offers long-lasting performance.
Each board is cut with a tongue and groove profile, making installation straightforward and ensuring a seamless finish on both walls and ceilings. Sustainably sourced and carefully prepared, this cladding is a reliable and authentic choice for any sauna project.

SAUNA WOOD CLADDING DIMENSIONS
18mm thickness x 95mm width (including 6mm overlap) 13 lengths required per linear meter.
Available in half meter packs of 7 x 2093mm or 4 x 2400mm
CALCULATING THE NUMBER OF LENGTHS OF CLADDING REQUIRED
Work out the number of lengths for each wall and ceiling individually
Number of lengths of cladding = Wall length in meters x 13
Length of cladding for walls = Internal ceiling height
IDEAL CEILING HEIGHT
If using an Oceanic Sauna Door the external height of the door frame is 1875mm. If building a free standing structure with frames and a base a typical height for the cladding is 1895mm.
A lower ceiling height makes a more efficient sauna as heat rises. If you prefer a taller sauna you will need to consider the area above the door also needs cladding.
For the ceiling cladding work out which direction you want the cladding to be fitted, normally along the longer distance for fewer fixings. Note longest cladding length Oceanic Saunas can supplu is 4.2m, lengths longer than our standard 1.895 or 2.1m will require a bespoke shipping quotation.
