Why choose Cleanstone™?
100% Recycled, Locally Made
Made from waste. Never ends up as waste. Every Cleanstone sheet is manufactured in New Zealand using waste diverted from landfills.

Custom Built & Customisable
Match any vision. Any palette. Any vibe. Whether it’s a feature wall, retail display, or branded office fit-out, we tailor it to your space and story.

Unique, and Functional
Our panels are made to last, with rich colours, textures, and patterns you won’t find anywhere else.

Ridiculously Durable
Smash it. Soak it. Drop it in the ocean—seriously. It still won’t rot. Use it in high-traffic spaces. Cleanstone keeps showing up.

Designed for Impact
Not just aesthetically, but environmentally. 1,250x less carbon than traditional building materials so every project reduces plastic waste and contributes to a circular future.

End-of-Life Buyback
We take it back, reprocess it, and make it new again. Forever.
