Black Onyx Plunge + Spa Mantra

First Day of the Rest of Your life
Welcome to the first day of the rest of your life when you slip into your new Black Onyx Plunge + Spa co Plunge Pool or Jacuzzi designed and assembled on Sydneys Northern Beaches by a wholly owned Australian Company. The Black Onyx Crystal is known for bringing out the deepest and truest reflection of your soul. It filters the sometimes shallow perception from the people that sometimes surround you and lets them see the depths of your personality. The Onyx is also a mysterious crystal which guides you in your spiritual journey bringing the hope of light in the tunnel of darkness. It is a powerful stone often worn by ancient warriors going into battle and protects the mind and the body from the negative fields that drain that carriers’ energy resulting in a positive emotional and physical well-being. It has countless healing and spiritual properties that date back thousands of years.

Our team is made up of talented tradespeople, designers and developers and we know what it takes to get real results. We keep the focus on providing the best experience for our customers that choose our products and pride ourselves for having an eye for products that are attractive as well as functional.

What We Do

Our Services
At Black Onyx Plunge + Spa co we saw the need for a modern alternative to the dated spa pools that, with the exception of some new jet technology, have changed very little in the last 30 years. In the tradition of the European open plan hot tub our plunge pools and spas are designed to be enjoyed by loved ones, friends and family for a welcome hot soak after a hard day at work, sport and play or alternatively can be operated at lower temperatures to cool off in the summer months with the elixir of your choosing. Aesthetically pleasing and apartment friendly there is no need to book an expensive crane company with council permits to take delivery of a monstrous spa carcass that takes up the majority of your space. Your Black Onyx Plunge + Spa co model is designed to be lightweight, ready to enjoy in 30 minutes from unpacking. Minimum maintenance is required which means more time to enjoy your new outstanding life courtesy of owning a Black Onyx Plunge or Spa.

Our newest additions to our range of health, wellness and leisure products are infrared saunas and ice baths for public use!
