Make it accessible. Your spa could be on a deck, a step or two from patio doors. Or, maybe on a terrace outside French doors, landscaped with shrubs or a small tree. Just remember, when it's cold out you won't want to go far in your towel and flip flops. Is privacy an issue? Add fencing, shrubbery or small trees for a sense of seclusion. You’ll need access to water, electricity, as well as your home.
