Product Description

All of our 'Classic Light Duty Commercial Finnish Sauna Cabins' are manufactured in our UK factory using traditional Grade A Scandinavian kiln dried spruce from managed and replanted forests, timber selection is crucial to the correct performance of the sauna cabin.  Spruce, which has both low heat absorption and low resin content is ideal. 

Our products are tested in the UK by the independent testing house 'Nemko' to meet British and European Standard. 
With over 40 years experience in Traditional Sauna Cabin manufacturing, we pride ourselves on quality at exceptional prices.

C4040 Light duty commercial Finnish sauna cabin 2500 x 2600 x 2000mm is supplied with a 12kw Floor standing sauna heater with OCSB digital remote controls.  
Peridotite rocks, these rocks are very dense and contain an extremely low number of air pockets, an igneous rock that is rich in iron and magnesium which posess a relatively high heat capacity making them ideal for use in saunas.
Reinforced 5 slat benches with supports, an extra duty base which lifts the walls panels off the floor, back rests, slatted floor mat (all supplied flat packed), a modern full height safety glass door with polished chrome & Ash wood handle and polished chrome hinges, optional upgrade to our larger 940mm disabled access door, heater guard, towel and fragrance rack, four 125ml bottles of Saunaroma (Lavender, Eucalyptus, Rosemary, Orange) headrests, traditional water bucket with liner and sculpted ladle, sand timer, thermometer, and lighting.  Assembly instructions, caution plate, operation and maintenance manual, water resistant bathing rules card and all fitting and fixings.

All panels are fully insulated with rockwool fibre, and are clad on both the exterior and interior faces allowing the cabin to be assembled free standing in almost any location without the need for brickwork, plastering or fixing to walls .
The door mounted in its frame is the same size as a panel and entirely symmetrical allowing its position on the to be readily interchanged, though the door must for safety reasons be opened outward it can be hinged either left or right. In many cabins it is possible to have more than one bench layout, we are happy to advise on individual circumstances.

Behind Bench Heater

The Oceanic behind bench heater with OCS-B controls is a wall mounted unit that is located behind a false wall at the rear of the cabin. There are many advantages of this model of heater


  • Built for heavy duty use
  • Protected heating elements
  • Rocks do not come into contact with heating elements 
  • Drip and eveporation trays control the water dosing. This prevents water being splashed directly onto the elements which is a common cause of element failure in standard sauna heaters.
  • A water dish and hose are fitted with the behind bench heater, users pour water into this dish mounted behind the false wall and the water is distributed evenly across the rocks.
  • Safer to use - prevents any accidental injuries from users being able to come into contact with the hot surfaces of the heater
  • More energy efficient

Extra Duty Base

We have increased the size of the base of the sauna making it more robust and lifting the panels off the ground providing a little more cabin height, lifting the wall panels off the ground also protects them from any water laying on the ground prolonging the life of the sauna.
