Harvia's olivine-diabase sauna stones are the gold standard for anyone serious about their sauna ritual. Cut to a generous 5–10cm size, these dense volcanic rocks are prized across Scandinavian wellness culture for the way they absorb intense heat and release it slowly and evenly — producing that characteristic soft, enveloping steam that defines a truly restorative sauna session. Whether you are loading a home electric heater or a traditional wood-fired stove, these stones deliver a consistent, luxurious experience every time.
Available in sizes from a handy 20kg bag right up to a 1,200kg bulk pallet, they are ideal for individual homeowners replacing worn stones, sauna installers stocking up, or wellness businesses furnishing multiple rooms. Every batch is delivered to the UK with free shipping, and we recommend a quick rinse before first use to clear any dust and ensure a clean, odour-free first heat.
All orders are delivered free to mainland UK addresses. Smaller quantities (20kg–200kg) are dispatched via courier, whilst the 1,200kg pallet is delivered kerbside by pallet freight — please ensure suitable access. Delivery typically takes 3–7 working days from dispatch. We recommend rinsing the stones thoroughly before placing them in your heater to remove any dust or surface residue prior to your first session.
At The Warm Living, we supply only the sauna products we would use ourselves — sourced from trusted Nordic and Baltic manufacturers with a proven track record. Our UK-based team is on hand to advise on stone quantities, heater compatibility, and everything else you need to create your perfect sauna.
