How long can you leave a spa without water?

A spa can typically be left without water for a short period, generally no more than a few days, depending on the model and materials used. Without water, the components can dry out, leading to potential damage, especially to seals and pumps. It's advisable to refill the spa before it sits dry for an extended time to maintain its integrity and longevity. Always refer to the manufacturer's guidelines for specific recommendations.
