SAUNARI by Sieraj 02 Indoor Sauna — 4 Persons, Heater Included

A sauna that keeps to itself — no glass facade for show, just every centimetre designed around the ritual. SAUNARI by Sieraj 02 is a four-person interior where what matters is heat, silence and wood under your hand — not a backdrop for Instagram.

Who it's for

For those who want an indoor sauna — for the garage, utility room, basement or a dedicated room in the house — rather than another garden structure on the plot. The signature by Sieraj line means refined detail: battens, benches, lighting and proportions carefully considered for the comfort of four people at once.

What's included

• Four-person sauna cabin, thermally modified wood construction
• Harvia electric heater with a full set of sauna stones
• Control panel and interior lighting
• Two-level benches with backrests
• Assembly manual and warranty card

Material and craftsmanship

Built from thermally modified wood — timber treated with heat to increase its resistance to moisture and high temperatures and to minimise movement over time. Made in the EU, under the quality supervision of the by Sieraj line. Lead time: 4–6 weeks from order.

The sauna ritual is more than heat — it's 15–20 minutes in which you slow down before returning to the rest of your day. SAUNARI by Sieraj 02 gives you that space in your own home: no stepping outside, no weather, no compromises in the middle of winter.
