Yes! You should definitely keep your cover on when not using your hot tub. Not only is this a good idea for safety, it’s also helpful for protecting your spa from direct sunlight.
Be aware, a cover that is not properly secured is a safety risk to children and could cause injury if blown off by the wind. You should also always remove the entire cover before using your spa.
It’s also important to avoid sitting, standing or placing heavy items on cover to avoid damage. Any snow accumulations over 2″ should also be removed.
