How to Insulate an Outdoor Spa Hot Tub

A hot tub will be more efficient with more insulation.

Insulation your hot tub can save you money each and every month that the hot tub is in operation. The more insulation your spa has, the more likely it will be that you can afford to operate it all year long. For the most part, installing spa insulation is a professional process that embeds additional layers of insulation within the wall of your tub. If you are interested in further insulating your hot tub, then you should seek the expertise of professionals in your area.

Instructions

1. Weigh the possible benefits of adding basic insulation to your hot tub. Basic insulation consists of a layer of polyurethane underneath the hot tub. This layer is thin, so this type of insulation is recommended only for indoor spa hot tubs.

2. Find out the differences between full foam insulation and layered insulation for your hot tub if you operate it outdoors. Full foam insulation is a type of rigid foam that you should install in multiple layers with a closed-cell, high density polyurethane foam. Layered, or blanket, insulation is layers of insulating material that you can easily move aside when removing spa panels for repairs. Both of these insulation types install between the cabinet walls and the spa hot tub shell.

3. Contact your local pool supply store and the manufacturer of you spa to find out if either one offers the service of insulating spas. If so, find out the basic price structure for the type of insulation you have decided on, or ask for recommendations. If not, get recommendations for contractors that provide this type of service.

4. Get price estimates from the contractors recommended if the pool supply store and spa manufacturer don't offer insulation services. Find out the price for the insulation and the labor, and make sure the insulation being used is the type you want. For full foam and layered insulation, apply the insulation in multiple layers for the best results, not just a single layer.
