There is nothing better than a soothing massage while listening to your favourite music, radio station, podcast or even a book and achieving this has never been easier thanks to our Platinum Melody system.

This high-quality Bluetooth system is fitted as standard to all models and is very simple to use. Simply search, then connect your smartphone or model device to the hot tubs Bluetooth and away you go.


With the Platinum Premium Shield, the heat is reflected back inwards and the wasted heat created by the pumps and other components can be recycled. The heat is then used to help maintain the temperature through heat transfer via the vast amounts of plumbing; this assists in reducing overall running costs.

The use of the new foil-coated cabinet panels also reflects the cold air out of the hot tub, whilst bouncing the heat back inwards, giving a double advantage.

You should notice a considerable difference in the heat retained in the hot tub, as well as a reduction in energy costs.


WIFI enabled controls is an optional extra and can be added to any Larry's Pool and Spas hot tub.

The Balboa Worldwide App (bwa™), is an app for your smart device (Android™ or iPhone®) that allows you to access your hot tub via a direct connection. Either connect to your local Wi-Fi network, or anywhere in the world where you have an internet connection to your smart device via 3G, 4G, or Wi-Fi hot spots.

* With the bwa™ app, you can ensure that your hot tub will be ready whenever you want to take a dip.

Instead of going outside and pressing buttons on the topside panel, the app lets you start the hot tub and change settings from your smartphone or tablet. The app provides full interface control, so you can set the temperature, turn pumps on and off, and even set filtration cycles.


We use high-quality Aristech Acrylic on all Larry's Pool and Spas hot tubs. The Aristech Acrylic brand has been supplying acrylic sheets from the world’s leading brands for the manufacturing of spas, swim spas, and hot tubs.
