Waterfall Feature

All Sparkling hot tubs are equipped with MP3/Bluetooth music system's with a standard 3.5mm jack allowing virtually any MP3 device to be plugged in. You can sit back and relax in the spa whilst listening to your favourite songs through the two mounted speakers which come as standard.

On the Premium range all our hot tubs come with Bluetooth connectivity! Music is another way to increase the users enjoyment whilst using their hot tub! Downtempo music can cause the brain to synch up with the beat and create alpha brain waves. These waves are often present when we're awake, but relaxed. Listening to smooth jazz, especially combined with nature sounds like waterfalls or thunder, can be especially soothing.

Scientists have claimed that the amount of lighting affects the regulation of emotions, such as happiness and sadness, through the nervous and endocrine systems. At Sparkling Spas we have used LED lighting in our hot tubs to enhance the users pleasure whilst using a Sparkling hot tub, by selecting lighting that only enhances the persons mood.

All Sparkling hot tubs come equipped with water level lighting, large LED in the footwell, corner skirt lights and the diverter lights. This gives the hot tub a very modern look but also improves the mental mood of the user.
