The right components are essential for a safe, high-performance sauna experience. This is your headquarters for all the critical sauna heater accessories you need to perfect your installation and get the most out of every session. From high-density sauna stones that produce the perfect steam to essential safety components like heater guards and heat shields, our collection features premium, manufacturer-approved parts to complete your wellness sanctuary.

Your guide to choosing the right heater accessories...

Do I really need special sauna stones?

Yes, absolutely. This is a critical safety rule. You must only use high-quality sauna stones that are specifically designed to withstand extreme, repeated temperature changes. Using regular landscaping rocks is incredibly dangerous, as they can contain hidden moisture that can cause them to crack or even explode when heated.

What is the purpose of a heater guard rail?

A heater guard rail is an essential safety feature for any traditional sauna. It's a simple wooden fence that creates a protective barrier around the hot stove, preventing accidental contact and burns. It’s a non-negotiable component for a safe sauna environment, especially in homes with children.

When do I need a heat shield or floor protection?

Proper heat shields and floor protection are required when installing a heater close to wooden walls or on a combustible floor. They reflect the intense radiant heat away from the surfaces, preventing scorching and reducing the required safety distances. They are a crucial component for a safe and code-compliant installation.
