How much does it cost to add a spa to a pool?

Adding an attached spillover spa to a custom pool typically costs $12,000–$25,000 additional. A detached spa may cost $15,000–$30,000 depending on size and features. The spa is most cost-effective when built simultaneously with the pool.

Can you add a spa to an existing pool?

Yes, though it's more complex than building them together. We can design and build an attached or detached spa that integrates with your existing pool's plumbing and equipment. We'll assess your current setup during a free consultation.

Overview

Pool-spa combos are our most popular design configuration, with an attached or detached spa providing a warm-water retreat alongside your swimming pool. Attached spas typically feature a raised spillover edge where heated water cascades into the pool, creating a beautiful visual and audible effect. Detached spas offer more design flexibility and can be positioned as standalone features with their own aesthetic. In Houston's climate, a spa extends your pool season significantly—many homeowners use their spa year-round, even on the coolest winter evenings.
