Can You Get a Custom Inground Pool with Built-In Spa Features?

Yes, you can absolutely build a custom inground pool with integrated spa features. Modern pool construction allows spas to be fully incorporated into your pool design, sharing plumbing and equipment while operating independently. These combinations offer hydrotherapy benefits, year-round use, and can increase your home's value by 7–10%.

Many Central Ohio homeowners assume a custom pool and spa combination is either too expensive or too complicated to pull off. The reality is that integrated pool-spa systems have become one of the most popular requests we receive at Aquatic Creations Ohio. With the right design approach and an experienced pool contractor, the results can be seamless—both visually and functionally.

This post covers everything you need to know: what a pool-spa combination actually involves, the design options available to you, the real benefits of building one, how the installation process works, and what it takes to maintain it long-term.

Key Takeaways

• Custom inground pools with built-in spa features are fully achievable and increasingly common among Central Ohio homeowners.

• Integrated spa features add therapeutic value, year-round enjoyment, and measurable property appeal.

• Professional design and installation ensure seamless functionality between your pool and spa systems.

• Financing options through Aquatic Creations Ohio make this level of customization accessible to more homeowners.

What Does a Custom Inground Pool with Integrated Spa Features Actually Include?

A pool-spa combination is exactly what it sounds like: a built-in spa (sometimes called a hot tub or spill-spa) that is permanently connected to your inground pool.

Unlike a freestanding hot tub sitting on a patio, an integrated spa shares the same structural design, materials, and often the same plumbing and filtration equipment as your main pool. Each zone—the pool and the spa—can be controlled independently for temperature, jets, and lighting.

Spa features typically included in a custom build are hydrotherapy jets, dedicated heating systems, blowers for air-jet pressure, LED lighting, and separate bench seating. The spa can also be designed to overflow into the pool, creating a spillover or cascade effect that looks stunning and adds the soothing sound of moving water.

What Are the Design Options for a Custom Pool and Spa Combination?

There is no single standard layout for pool-spa combinations. The configuration you choose depends on your yard size, aesthetic goals, and how you plan to use the space.

The most common design styles include:

• Level spa: The spa sits flush with the pool on the same plane. It's often the most affordable configuration and works well for a clean, modern look.

• Elevated spa with spillover: The spa is raised above the pool deck, with water cascading down into the main pool. This creates a dramatic focal point and is one of the most popular choices for custom builds.

• Detached spa: The spa is built as a separate but adjacent structure, giving both zones their own defined space within the backyard.

• Perimeter spa: Water runs over the spa's edge on all sides, creating a sophisticated, rimless appearance that works especially well with contemporary designs.

Beyond configuration, you can customize materials, tile work, interior finishes, and lighting to match the rest of your outdoor living space. Whether your style leans toward clean geometric lines or a freeform, organic layout, both can accommodate a built-in spa without compromising the overall design.

What Are the Real Benefits of a Pool and Spa Combination?

The appeal of a pool-spa combination goes beyond aesthetics. There are concrete, practical reasons Central Ohio homeowners choose this setup.

Hydrotherapy and physical wellness: Warm water and jet pressure offer well-documented health benefits. According to research published by the National Institutes of Health (PMC4049052), hydrotherapy supports muscle recovery, reduces pain, and improves range of motion. This makes a built-in spa particularly valuable for anyone dealing with joint pain, chronic soreness, or post-workout recovery.

Extended use throughout the year: Ohio winters are cold. A heated spa means you can still use your backyard water feature in the colder months when the main pool is closed. It extends the season considerably and gives your investment more value across twelve months, not just the summer.

Property value: A well-maintained inground pool can increase a home's value by 7–10%, according to HFS Financial (2026). Adding spa features further increases the appeal, especially in upscale Columbus-area neighborhoods where buyers expect premium outdoor amenities.

Versatile entertainment: A pool handles active recreation—swimming, playing, cooling off. A spa handles something different: winding down, socializing in small groups, or recovering after physical activity. Having both in one space means your backyard can serve a wider range of purposes and guests.

What Does the Installation Process Look Like for a Pool and Spa?

The process begins long before any digging happens. We start with a consultation to understand your goals, yard dimensions, soil conditions, and budget. Central Ohio's clay-heavy soil requires careful excavation planning, and Columbus city permits must be obtained before construction begins.

A standard building permit in Columbus runs approximately $300, with additional electrical and plumbing permits required depending on your setup.

Once planning and permitting are complete, the process moves through these phases:

1. Excavation: Digging out the area for both the pool and spa according to the engineered plans.

2. Structural work: Installing the shell, whether fiberglass, vinyl, or gunite. Fiberglass pool installation is the most popular choice in Central Ohio due to its durability against Ohio's freeze-thaw cycles.

3. Plumbing and electrical: Running the lines that will connect your spa jets, heaters, blowers, and lighting to the main equipment pad.

4. Finishing: Applying interior surfaces, coping, decking, and any tile or water features.

Timeline varies based on design complexity, material selection, and weather. Most custom inground pool projects with integrated spas run between 6 and 12 weeks from excavation to final walkthrough.

How Do You Maintain a Pool and Spa System Long-Term?

Maintaining a pool-spa combination follows the same core principles as maintaining any inground pool, with a few additional considerations for the spa zone.

Water chemistry needs to be monitored regularly. The spa runs at higher temperatures than the pool, which means it can burn through sanitizer faster and require more frequent testing. Keeping pH, alkalinity, and sanitizer levels balanced protects both the equipment and the people using it.

Filters should be cleaned on a regular schedule, and the spa jets and blower lines should be inspected seasonally. Heating systems need annual checks to ensure efficiency, especially heading into winter. Ohio's freeze-thaw conditions mean proper winterization of both the pool and spa is not optional—it protects your plumbing, equipment, and shell from frost damage.

Our pool contractor services include ongoing maintenance support so that routine care doesn't fall entirely on your shoulders. Whether you want a seasonal service plan or help troubleshooting a specific issue, having a trusted local partner makes long-term ownership much easier.
