Sauna Stone Supply and Replacement, Nairobi Kenya
Sauna stones are the beating heart of the sauna. When water is ladled onto the heater, it is the stones that store the heat, flash the water into vapour, and release the soft steam Finns call loyly. Over time, however, every stone wears out. Thermal cycling cracks and crumbles even the best rocks, and degraded stones stop producing good steam, strain the heater elements, and can even damage the equipment. Refitec Kenya supplies and replaces sauna stones in Nairobi and throughout Kenya, for home saunas, hotels, gyms, and spas.
Why Sauna Stones Matter
In an electric sauna heater, stones surround the heating elements and serve several purposes at once. They store heat so vapour can be produced when water is thrown, they distribute heat evenly through the room, and they protect the elements from direct splashing, which causes thermal shock and premature failure. When stones crack and fragment, chips fall to the bottom of the heater, airflow is reduced, elements overheat, and the vapour becomes thin and weak. Old stones are one of the most common, and most overlooked, causes of a disappointing sauna.
Types of Sauna Stones We Supply
Refitec Kenya supplies genuine sauna stones selected for high heat capacity and resistance to cracking:
- Olivine diabase stones: The classic heater stone, dense and durable, offering excellent heat storage and good steam yield
- Peridotite stones: Premium stones that withstand repeated water throws and produce exceptionally soft vapour
- Vulcanite and granite-based stones: Economical options for lower-usage home saunas
- Scented and aromatic stone options: Stones paired with essential oil dosing for fragrant steam
All stones are supplied in correctly graded sizes, washed, and ready to stack.
Our Supply and Replacement Process
We begin by identifying your heater model and stone capacity, since manufacturers specify exact stone quantities and diameters for safe operation. We supply the correct graded stones, then, for replacement service, our technicians remove the old stones, vacuum debris and stone dust from the heater, inspect the elements for damage caused by crumbling stones, and restack the new stones with correct density and orientation, tighter around the elements and looser at the top, exactly as the manufacturer requires. The heater is then run through a full cycle to bed the stones and eliminate new-stone odour. Full replacement is recommended annually for heavily used commercial saunas and every two to three years for home saunas.
Signs Your Stones Need Replacement
Replace sauna stones when thrown water produces weak or no steam, stones appear cracked, crumbled, or flattened with visible dust at the heater base, the sauna takes longer to heat, elements fail prematurely, or a faint burning smell develops during heating. Commercial operators should treat stone replacement as scheduled maintenance rather than waiting for failure.

Frequently Asked Questions
How often should sauna stones be changed? Heavily used commercial saunas should have stones replaced annually; home saunas typically every two to three years. Can I buy stones and stack them myself? You can, but correct stacking density and orientation around the elements matter for both steam quality and heater life, which is why many customers choose our replacement service. Which stones give the softest steam? Peridotite and olivine diabase are the premium choices, storing heat well and withstanding repeated water throws. Do you deliver countrywide? Yes, with same-day delivery available in Nairobi for in-stock grades.
