Can You Add a Spa to an Existing Pool During a Renovation?
Yes, a spa can be added to an existing gunite pool during a renovation. For homeowners in League City, Pearland, Friendswood and throughout Greater Houston, a pool renovation is often an ideal time to add one because structural, plumbing, equipment and finish work may already be taking place.
Whether you’re envisioning a raised spillover spa connected to your pool or a standalone spa incorporated into a larger outdoor living space, completing both projects together can create a more cohesive result. McKinney Custom Pools regularly helps homeowners throughout League City, Pearland, Friendswood and Greater Houston incorporate custom spas into pool renovation projects.
Why Add a Spa During a Pool Renovation?
Pool renovations typically involve replacing finishes, updating plumbing, modifying decking and upgrading equipment. Since these systems are already being evaluated or replaced, a renovation can be a natural time to incorporate a spa into the overall design rather than opening up the pool and backyard again in the future.
Combining both projects offers several advantages:
- A seamless design that looks like the spa was always part of the original pool
- One construction timeline instead of two separate projects
- The opportunity to upgrade equipment to support the pool and spa together
- Improved functionality and expanded outdoor living space
Attached Spillover Spa vs. Standalone Spa
Most homeowners choose one of two spa configurations when renovating an existing pool.
Attached Spillover Spa
An attached spillover spa shares a wall with the pool and typically features a spillway where water flows from the spa into the pool. It’s a popular option because it can create a unified appearance and an attractive visual focal point.
Benefits can include:
- Continuous spillway water movement
- Shared equipment in many designs
- Seamless integration with the existing pool structure
- A clean, cohesive appearance
Standalone Spa
A standalone spa offers more flexibility in placement and can become its own destination within the backyard.
This option may work well when:
- Space limitations make an attached spa impractical
- Homeowners want additional privacy
- The spa will be used independently from the pool
- The backyard layout naturally lends itself to separate gathering spaces
During a renovation consultation, McKinney Custom Pools helps homeowners determine which option best complements their existing pool, backyard and lifestyle.

What Does Adding a Spa to an Existing Pool Involve?
Adding a spa during a pool renovation may involve:
- Structural modifications to the existing gunite pool
- New or modified plumbing for spa jets and circulation
- Heating and equipment modifications
- Electrical work for spa controls and equipment
- Concrete and steel reinforcement
- Tile, coping and interior finish updates
- Deck modifications to accommodate the new spa footprint
Depending on the design, adding a spa may require new or modified plumbing, heating, circulation and control systems, making equipment planning one of the most technical parts of the project.
Many homeowners also use the renovation as an opportunity to consider upgrades such as:
- Pool automation systems
- LED lighting
- Variable-speed pumps
- Saltwater systems
- Water features
- Energy-efficient equipment
These upgrades can improve convenience, efficiency and the overall backyard experience.
How Much Does It Cost to Add a Spa to an Existing Pool?
The cost of adding a spa to an existing pool depends on the spa design, structural modifications, plumbing and equipment requirements, finishes, decking changes and other upgrades included in the renovation.
The existing pool and backyard can also affect the scope of the project. Access, available space and the condition of the current pool and equipment all need to be considered.
Because every existing pool and backyard is different, an on-site evaluation is the best way to determine the scope and cost of adding a spa.

Does the Spa Have to Match the Pool’s Existing Finish?
No. A new spa does not necessarily have to match the pool’s existing finish.
Many homeowners choose to match the existing tile, coping and interior finish so the spa appears as though it was always part of the original design.
Others use the renovation as an opportunity to update the finish, tile and coping throughout both the pool and spa for a fresh, cohesive appearance.
Can a Spa Be Added to Most Existing Gunite Pools?
In many cases, yes. Gunite pools offer flexibility for renovation projects because their steel-reinforced concrete structures can often be modified to accommodate a custom spa.
However, the existing pool structure, available space, plumbing, equipment and site conditions all need to be evaluated before determining whether and how a spa can be incorporated.
Every renovation begins with a thorough evaluation of the existing pool, equipment and backyard before the spa design is finalized.

What Are the Benefits of Adding a Spa to an Existing Pool?
A spa can provide much more than another place to relax.
Homeowners who add a spa during a renovation may enjoy:
- Year-round relaxation, even when the swimming pool isn’t in use
- Hydrotherapy and muscle recovery
- A dedicated space for entertaining family and friends
- Increased enjoyment of the backyard
- A natural complement to a custom outdoor living space
A professionally designed spa can also become a focal point that complements the existing pool and overall backyard design.
Is a Pool Renovation the Best Time to Add a Spa in Greater Houston?
If you’re already planning to resurface your pool, replace tile or coping, update decking or upgrade equipment, it’s worth discussing a spa addition as part of the same project.
For homeowners in League City, Pearland, Friendswood and Greater Houston, combining a spa addition with a planned pool renovation can create a more complete backyard transformation while avoiding separate construction projects over time.
It also gives your pool builder the opportunity to consider the pool, spa, equipment and surrounding outdoor space together rather than treating the spa as a separate project later.
Does Adding a Spa to an Existing Pool Require Permits?
Typically, yes. Because adding a spa can involve structural modifications, plumbing, electrical work and equipment installation, permits may be required depending on the scope of the project and local jurisdiction.
An experienced pool builder can coordinate the permitting process and make sure the project complies with applicable local building requirements.

Frequently Asked Questions About Adding a Spa to an Existing Pool
Can you add a spa to an existing pool?
Yes. In many cases, a custom spa can be added to an existing gunite pool during a renovation. The existing pool structure, available space, plumbing and equipment should be evaluated to determine the best way to incorporate the spa.
What’s the difference between an attached and standalone spa?
An attached spillover spa is incorporated into the pool design and typically includes a spillway between the spa and pool. A standalone spa is built separately, providing greater flexibility in placement and independent use.
Does adding a spa require new plumbing?
Typically, adding a spa requires new or modified plumbing to accommodate jets and circulation. The exact plumbing and equipment requirements depend on the spa design and how it will operate with the existing pool.
How much does it cost to add a spa to an existing pool?
The cost depends on the spa design, structural modifications, plumbing and equipment requirements, finishes, decking and site conditions. An evaluation of the existing pool and backyard is the best way to determine the scope and cost of the project.
Will adding a spa increase operating costs?
Operating costs may increase when the spa is heated and used. Equipment selection, automation and how frequently the spa is heated can all affect ongoing operating costs. During your renovation consultation, McKinney Custom Pools can recommend equipment based on how you plan to use your pool and spa.
Does a spa addition require permits?
Permits are typically required when a spa addition involves structural, plumbing or electrical work. Requirements can vary by jurisdiction, so the permitting needs should be determined based on the specific project and location.
Do you have to renovate the whole pool to add a spa?
No. A spa may be added without completely renovating every part of the pool. However, many homeowners choose to update finishes, tile, coping, decking or equipment at the same time because related construction work is already underway.
