Features to Consider

Size

Before making a purchase, it’s essential to ensure that your garden/house can accommodate the swim spa model that you’re interested in. This includes checking the dimensions, access routes for delivery, and whether there’s sufficient clearance around the spa for safe use, maintenance, and ventilation. Swim spa hot tubs are typically the longest swim spas in the market so bear this in mind when sizing up the space in your garden.

Warranty

When investing in a swim spa, the last thing you want is the added stress of unexpected repairs or breakdowns. Make sure to contact your proposed dealer ahead of time to ensure you’re backed by a solid warranty plan. A comprehensive warranty gives you peace of mind and protects your investment for years to come.

Energy Efficiency

Choosing an energy-efficient swim spa is going to make a big difference when it comes to your energy bills. That’s why it’s important to speak with your dealer in advance about the energy performance of the model you’re considering. Look for features like full-foam wrapped insulation, a high-quality thermal cover, and heat pump compatibility.

LED Lighting & Sound System

Having a range of different lighting options to play around with can really elevate your swim spa experience – especially during evening sessions. The combination of light, sound, and warm water creates a relaxing escape that helps lift your mood and boost your mental wellbeing.
