Built with quality materials

We don’t cut corners — literally or figuratively. Every custom sauna is crafted with premium, durable materials chosen to withstand New Zealand conditions and deliver that timeless sauna heat. From sustainably sourced timbers to precision hardware, we balance form and function so your sauna not only looks incredible but performs for years to come.

Our Build Process

Bringing your sauna to life is simple. We start with a design consultation to understand your space, style, and goals. From there, we provide a clear plan and transparent quote. Once you’re happy, our team takes care of the build — either on-site or in our workshop for delivery. We handle the details, keep you in the loop, and make sure every step is stress-free. All you need to do is step inside and relax.

Investment

A custom sauna is more than a purchase — it’s an investment in your health, lifestyle, and home. Prices vary depending on size, materials, and design, but every project includes our commitment to quality craftsmanship and longevity. Think of it as wellness that pays you back: better recovery, deeper relaxation, and a property feature that adds serious value.
