Frequently Asked Questions

The iHKA outdoor sauna measures 226cm (width) × 245cm (depth) × 232cm (height) externally, with approximately 5.5m² of interior space. It comfortably accommodates 3 to 4 people with two-tier ergonomic benches. Full specifications live on the sauna page.

Plan for at least 260cm × 280cm of clear, level floor space, with safe clearance around the cabin and from any combustible material. We confirm exact site requirements as part of the quotation, including the chimney clearance for the wood-burning option.

Yes — the modular design works indoors or outdoors. Indoor installations need adequate ceiling height (we recommend at least 240cm), suitable flooring and, for the Mini IKI wood-burning option, a compliant chimney route. Get in touch and we will assess your space.

Approximately 850kg fully assembled. The cabin ships on a single pallet and we lift it onto its prepared base on installation day. The base must be flat, level and able to support the weight — typically a concrete slab, paving on compacted hardcore, or a structural deck designed for the load.

Professional assembly is completed in a single day. The sauna ships fully prefabricated on one pallet, and our trained team handles the complete installation including setup and usage training.

iHKA saunas are manufactured in Masku, Finland and distributed from Antwerp, Belgium. We deliver to Belgium, the Netherlands, Germany, France, Austria, Sweden, Ireland, Italy, Romania, Spain, and the United Kingdom.

The sauna is shipped fully prefabricated on a single pallet and delivered by truck to your site. Our team takes responsibility for transport, lifting the cabin onto its prepared base, full assembly, commissioning and a usage walkthrough.

Lead times vary by configuration and season, but a typical iHKA is delivered and installed eight to twelve weeks after order confirmation. We confirm exact dates once your configuration is finalised.

Every iHKA includes a full one-year warranty covering manufacturing defects in the cabin, the heater, and our installation work. Harvia and IKI heaters carry their own manufacturer warranties on top, and we extend support beyond year one for owners who maintain the sauna per our care guide.

After every session: open the door fully, wipe pooled water from benches and floor, leave the door slightly ajar for one to two hours so the cabin dries completely, and switch off the electric heater (or wait for ashes to cool before closing the wood-stove damper). Five minutes of airing after use is the single most important habit. Our seasonal care guide covers weekly, quarterly and annual tasks.

IKI recommends sweeping every three years for occasional holiday use, and annually for any regular or year-round use. In Belgium, sweeping by a registered specialist is a regional regulatory requirement and is normally a condition of household insurance. Always use a flexible nylon brush, never a metal one.

Both Harvia and IKI recommend rearranging stones at least annually and discarding any that are cracked or disintegrated. For typical private use, plan a full refresh every three to five years; for intensive use, an annual full replacement is the standard. Our owner's care guide walks through the full annual stone check.
