Yes, you can use your hot tub all year long! In fact, hot tubs are designed to be used year-round. Insulation helps to keep heat in so you can enjoy your hot tub even when the weather is cold.
During the summer months, you can turn down the temperature of your hot tub to make it more refreshing. A temperature around body temperature (around 98-100°F) can be particularly refreshing on a hot summer day. In the cooler months, you may want to keep the temperature a bit higher to help you stay warm, although this will depend on your personal preferences.
Overall, hot tubs are designed to be used year-round, and with proper insulation and an insulating cover, you can enjoy your hot tub no matter what the weather is like outside. Whether you want to relax in a warm, soothing hot tub on a cold winter day, or cool off in a refreshing hot tub on a hot summer day, a hot tub can provide a welcome retreat all year round.
