Can a hot tub be left unused for a long time?
Essential maintenance should continue even if your hot tub is not being used. If this is not possible it should be winterized. This is also recommended for any hot tub or swim spa are not being where temperatures below freezing point are likely. To winterize a hot tub, first the water is drained away, then the internal plumbing system is drained, then the hot tub is covered.
