The Freeflow Spas® Collection


Welcome to Hot Spring Melbourne, your ultimate destination for luxurious spa pools designed to redefine comfort and energy efficiency. The Hot Spring Tristar is no exception—a compact marvel built to bring you the perfect balance of luxury, affordability and eco-consciousness.

The name gives you a sense of this hot tub's point of difference, or perhaps more accurately, three points of difference. The unique triangular shape of the Tristar makes it an ideal addition to Melbourne backyards that are becoming ever more compact. The design allows you to capitalise on unused corners in your backyard, or on your deck or balcony. Experience the Hot Spring Tristar today, and discover a way to create your own personal haven, where you can shake off all the stress of the day. Talk to us today, and elevate your lifestyle with the Tristar.

Luxurious Hydrotherapy

With 17 meticulously positioned jets, the Tristar delivers a rejuvenating hydromassage that will help you relieve tension, supporting both your physical and mental health.

By taking our renowned hydrotherapy experience and wrapping it in the space-saving design of the Tristar, we’re aiming to help make hydrotherapy massage available to as many people as possible. 

Shaped uniquely like a triangle, the spa pool fits much easily into more unconventional outdoor areas—it can often fit places you might be surprised by. This includes small decks or balconies, all while accommodating up to three adults.

Effortless Efficiency

With potential daily costs as low as $1, depending on local rates, you can luxuriate in your spa pool without breaking the bank. Our advanced insulation and thermal cover work together to trap warmth more effectively, minimising energy consumption and keeping your spa pool ready to go.

Quick Setup

Experience hassle-free setup with the Tristar—as part of our Freeflow collection it comes equipped with Plug-N-Play technology. No need for any complex electrical installations, just simply fill your new spa pool up and plug it into a standard outdoor power outlet before indulging in near-instant relaxation.

Durability Redefined

Crafted with precision and care, the Tristar's rotomolded unibody is a testament to our focus on exceptional quality control. 

This unique manufacturing technique eliminates the need for internal supports, making the Tristar an affordable option that’s also notably lightweight yet remarkably strong. This means the Tristar will last you for years and is light enough to move when you do too, allowing you to take your ticket to pure relaxation with you wherever you go.

Clean, Clear Water

Enjoy the crystal clear waters of your new Tristar with the optional CD Ozone System. By harnessing the power of concentrated ozone bubbles to neutralise contaminants, this smart system keeps your water pristine and perfect for you to relax in, year round.
