Everything you need—nothing you don’t

From the heater to the chimney, base, and stones, this bundle delivers the full ritual. No guesswork, no scrambling for parts. Just add fire (and maybe a plunge pool).

Save $163 by bundling

Individually, it adds up. Together? You pocket $163 and get every critical component in one click.

Engineered in Finland, built to endure

CE-marked, soot-fire resistant, and freeze-thaw tested. If it can survive a Nordic winter, it can handle your backyard.

Heat that holds its own

The Harvia M3 wood-burning heater packs 16.5 kW of power and an 88 lb stone bed—so you get steady, saturating steam every time.

Safety that disappears into design

A protective sheath and heat-shielded base reduce clearance requirements without ruining the view. Black. Sleek. Solid.

Vertical, smart, and scalable

The chimney system installs vertically, extends easily, and includes everything down to the rain cap and insulation kit.

Setup

Home Ready: No – Professional installation recommended for chimney, fire shielding, and clearance

Electrician required: No – Fueled by wood; no power source needed

Assembly: Ships with full installation manuals; chimney system designed for vertical installation only
