Heat-treated spruce that resists decay and barely moves with the weather

Thermowood starts as the same Nordic spruce as our standard spruce enclosure, then goes through a thermal modification process: heat and steam only, no chemicals. The treatment changes the wood's cell structure, so it resists decay and barely expands or shrinks with changes in moisture and temperature, unlike untreated spruce. It's built to the Square 1700L hot tub shell's exact shape. Made by Plastprofiil, a composite factory in Riisipere, Estonia, manufacturing since 2012.

Key Features

  • Decay-resistant - Heat treatment removes the moisture and nutrients rot, fungi and insects need to thrive.
  • Dimensionally stable - Panels stay flat and joints stay tight outdoors, unlike untreated spruce.
  • Square design - Follows the square shape of the shell exactly, matched to the Square 1700L tub.
  • Heat and steam only - No chemicals used in the modification process.
  • Arrives assembled - Ships fully built and ready to position as standard; unassembled delivery is available on request.
