Harvia AC4000 – White Sauna Stones, Rounded (5–10 cm)

Description:

Elevate your sauna’s look and ambiance with the Harvia AC4000 White Sauna Stones. These beautiful rounded stones feature a smooth texture and clean white finish, providing a sophisticated decorative accent to your sauna heater.

Designed exclusively for decorative use, the AC4000 stones create a brighter, more elegant aesthetic while contributing to a softer, cleaner steam experience. To maintain proper heat circulation and performance, these stones are meant to be placed only as a top layer above traditional split-face stones (such as Harvia AC3020).
