A lap pool, but not as you know it. In our Fastlane Pools swim spa range, Hot Spring has been able to condense the traditional lap pool down into a space-saving, money-saving swim spa that offers a superior experience. There’s a reason why lap pools are seen as the ultimate in residential luxury - they are expensive and need space until now. With Fastlane Pools swim spas you can enjoy a lap pool that is infinitely long but that also fits neatly into your backyard or even onto your deck.
