Installing a spa or hot tub can transform your home into an enjoyable, relaxing oasis. There are quite a few options when it comes to choosing your new spa. One of the most affordable options is an inflatable spa. These sturdy spas are easy to install and can hold up to four people. Wooden hot tubs can give your home a rustic feel. Acrylic spas are an above-ground spa option. Both wooden spas and acrylic spas need a permanent base, such as a deck. Both come in many sizes and styles to hold up to ten people.
