Introducing our newest addition. 

The Nautilus: A Vessel of Universal Design

The Sulis Nautilus Hot Tub is more than a sculptural marvel, it’s a physical embodiment of one of the most profound patterns found in nature: the golden ratio.

This ratio appears in the spiral of galaxies, the twist in animal horns, the structure of DNA, and the arrangement of leaves, flowers, and pinecones. It’s how sunflowers optimise sunlight, how the body balances, and how storms breathe across the sea.

Across cultures, this ratio has been revered as a sign of cosmic order, a sacred geometry that reflects the intelligence of nature, building complexity through simplicity. 

Artists, architects, and mystics have used it to express divine harmony. It's a reminder that everything, from the smallest shell to the largest storm system, follows patterns and those patterns are beautiful.

By entering the Nautilus Hot Tub, you are immersing your own vessel into one of those patterns.

You soak not just in water, but in a space whose form mirrors the intelligence of the universe, a shape echoed in your own biology, in the spiral of your ear, in the geometry of your heartbeat.

Behind its flowing lines lies cutting-edge performance: the Rakaia Nautilus Hot Tub is equipped with state-of-the-art heat pump technology. Offering seamless and efficient heating and cooling.  

Whether nestled into a landscape or standing as an architectural feature, the Nautilus is more than a hot tub. It’s a living expression of the universe’s design code, an invitation to immerse, unwind, and return to source.
