The Mack Daddy by Thursday Pools is Thursday Pools’ most ambitious rectangle pool design, and the first design they have ever produced with a fully integrated spa built directly into the pool shell itself. At 16′ x 36′ with a flat-bottom 4’8″ standing depth, it is a single fiberglass structure that contains a spa with spillway, a tanning ledge with water depth of 8 to 10 inches, wide entry steps flanked by wraparound bench seating, and a wide-open swim lane with room for laps, games, and everything in between. Thursday Pools calls it “a beautiful, crowd-pleasing pool” that offers “something for everybody,” and the design earns that description specifically because the four distinct zones of the Mack Daddy are built into a single shell, not assembled from separate structures placed side by side. If your household wants a pool that does everything, the Mack Daddy was designed for exactly that.

What Is the Mack Daddy Pool?
The Mack Daddy is a rectangle fiberglass pool available in one size: O.D. 16′ x 36′ with a flat-bottom standing depth of 4’8″ throughout the swim area. It is Thursday Pools’ first design to feature a fully integrated spa with spillway as part of the pool shell, not as a separately installed companion structure. Thursday Pools provides specific depth data for the tanning ledge: it is 14 inches in structural depth, with an operating water depth of 8 to 10 inches, large enough for standard Ledge Loungers and wide enough for younger swimmers who are not yet ready for the full pool depth.
Wide entry steps are flanked by wraparound bench seating on both sides, creating an intuitive entry point and a comfortable social zone adjacent to the steps. The open swim lane runs with a consistent 4’8″ flat-bottom sport depth throughout the pool shell, which Thursday Pools identifies as ideal for games, water aerobics, laps, and active entertaining. The Mack Daddy is also auto-cover ready.
What the Mack Daddy Is Not
The Mack Daddy is not a diving pool. Its 4’8″ flat-bottom uniform depth is a sport pool depth, not a variable-depth design with a traditional deep end. If your family’s priority is a Type One diving pool with a deep end, the Thursday Pools Monolith, at 8’6″ in the deep end, is the right model. The Mack Daddy’s uniform depth is a deliberate design choice that makes the entire 36-foot length usable for standing, games, and social activity rather than reserving the deep end for advanced swimmers only.
It is also not a multi-structure installation assembled from separate components. The Mack Daddy’s integrated spa is molded directly into the pool shell, which means it arrives as a complete, single-piece fiberglass structure rather than a pool-plus-separate-spa project. For homeowners who want to add spa functionality to their backyard without the footprint, planning, and cost of a separate standalone spa installation, the Mack Daddy accomplishes that within a single 16′ x 36′ shell.
Why Thursday Pools?
Thursday Pools is the only fiberglass pool manufacturer in the United States to hold ISO 9001 certification for quality management and ISO 14001 certification for environmental stewardship, both independently audited. The Mack Daddy is one of their most recent designs, introduced in early 2025, and it reflects the same manufacturing standards and innovation philosophy that have driven Thursday Pools since their founding.
Three Optional Innovations from Thursday Pools are specifically available for the Mack Daddy:
Backfill Eliminator®: The Mack Daddy’s tanning ledge creates a large, shallow area that is structurally more demanding to backfill correctly than a standard pool wall. The Backfill Eliminator® is a Thursday Pools innovation specifically designed to provide structural support for shallow entry areas and tanning ledges, ensuring long-term stability in areas where conventional backfill techniques can fail over time. Thursday Pools lists it as an Optional Innovation on the Mack Daddy’s page for exactly this reason.
Geo-Anchor Pool Wall® (U.S. Patent No. 9593455): A structural reinforcement system for the pool wall, relevant for any inground fiberglass pool in Ohio where freeze-thaw cycles create seasonal ground pressure against the shell.
Lucky 7 Skimmer®: The first skimmer in the fiberglass pool industry designed specifically for fiberglass pools. The 7-degree angle and purpose-built mounting plate improve skimming efficiency, optimize water level management, and produce a cleaner finished integration at the pool wall.
Why Fiberglass, and Why the Mack Daddy?
The Mack Daddy’s four integrated zones, spa, tanning ledge, bench seating, and swim lane, exist in fiberglass because fiberglass manufacturing makes them possible in a single structure. A concrete pool with a built-in spa, a tanning ledge, and wraparound benches requires custom formwork for every zone, a months-long construction process, and eventual resurfacing across all surfaces as the concrete ages. The Mack Daddy arrives as a precision-molded one-piece shell that installs in approximately 2 to 3 weeks and carries the same lifetime structural warranty and algae-resistant gel coat as every other Thursday Pools design.
The flat-bottom 4’8″ standing depth also reflects a deliberate design philosophy that fiberglass manufacturing enables cleanly. The uniform depth makes the entire pool equally accessible for all users regardless of height or swimming ability, allows the swim lane to run the full length without a shallow-to-deep transition restricting activity at one end, and supports the tanning ledge and integrated spa at their respective depths without requiring structural transitions between zones.
Thursday Pools estimates approximately $1,800 per linear foot as a ballpark installation figure for fiberglass pools. At 36 feet, the Mack Daddy’s all-in-one design replaces what would otherwise require a primary pool plus one or two separate structures, and that consolidation has real value for the homeowner who wants everything built as a single project.

Mack Daddy Pool FAQs
What makes the Mack Daddy's integrated spa different from a separately installed spa?
Thursday Pools specifically identifies the Mack Daddy as their first design to feature a fully integrated spa with spillway built into the pool shell itself. This means the spa is not a separate fiberglass structure placed beside the primary pool and plumbed independently. It is molded directly into the 16′ x 36′ shell as one of the pool’s defined zones. The practical difference is significant: the integrated spa shares the same continuous gel coat surface as the rest of the pool, creates a visual unity between the spa and swim areas that separate structures rarely achieve, and eliminates the gap or transition between the primary pool and a separately installed spa. Thursday Pools describes the integrated spa as “the perfect space for parents to watch over splashing children and connect with friends and family,” positioning it at the end of the pool near the entry steps where adults can soak and supervise simultaneously.
How does the tanning ledge work, and what is its water depth?
Thursday Pools provides specific depth data for the Mack Daddy’s tanning ledge: it is 14 inches in structural depth, with an operating water depth of 8 to 10 inches in use. This depth is standard for sitting on a Ledge Lounger chair in shallow water, where the water covers your calves while you recline in the sun. The ledge is wide enough for multiple Ledge Loungers and also functions as a wading area for younger swimmers who are not yet ready for the pool’s full 4’8″ depth. The tanning ledge is a dedicated shallow zone built into the Mack Daddy’s shell, not a tacked-on feature, and it is positioned to give younger swimmers a safe, visible, and clearly bounded area within the overall pool structure.
What is the swim area like, and how does the flat-bottom depth affect pool use?
The Mack Daddy’s swim lane carries a flat-bottom uniform depth of 4’8″ throughout the entire pool shell. This is classified as a sport pool depth, meaning adults of average height can stand comfortably throughout the pool, games and water aerobics can happen across the full length, and there is no shallow-to-deep transition that divides the pool into functional zones by depth. The swim lane is open and unobstructed, giving swimmers a clear path for laps, water aerobics, or casual floating. Thursday Pools also notes the flat-bottom design as ideal for entertaining and active family use where everyone in the water should have equal access to the full pool area.
Why is the Backfill Eliminator® specifically listed for the Mack Daddy?
The Mack Daddy’s tanning ledge creates a large, shallow area that presents the same backfill challenge Thursday Pools identifies for their Sandal Beach Entry pool. The Backfill Eliminator® is a Thursday Pools innovation specifically designed to provide structural support beneath shallow tanning ledge and beach entry areas, where conventional backfill techniques can produce voids or settling over time if not executed correctly. Thursday Pools lists the Backfill Eliminator® as an Optional Innovation on the Mack Daddy’s page specifically because of this structural consideration. Ohio Paradise Pools has experience with the precision backfill work the Mack Daddy’s tanning ledge requires and handles this as a standard part of every Mack Daddy installation.
Is the Mack Daddy suitable for children of different ages?
Yes, and the Mack Daddy’s four-zone layout is specifically designed with this in mind. The tanning ledge at 8 to 10 inches of water depth gives very young children and non-swimmers a clearly bounded shallow area. The entry steps and wraparound bench seating allow parents and grandparents to sit in the water at a comfortable depth and remain physically close to younger swimmers. The open swim lane at 4’8″ gives older children and adults full use of the pool. And the integrated spa gives adults their own therapeutic space while keeping everyone in the same structure and in clear visual contact. Thursday Pools describes the Mack Daddy as “a beautiful, crowd-pleasing pool” with “something for everybody,” and that is exactly how the zone structure supports a family with a wide range of ages and abilities.
Is the Mack Daddy auto-cover ready?
Yes. Thursday Pools specifically designed the Mack Daddy to accept an automatic pool cover. Thursday Pools notes that auto covers help ensure no one can enter the pool without the owner’s knowledge and keep the pool clean to lower maintenance costs, both of which are important for a structure with the Mack Daddy’s complexity and investment level. In Ohio, an auto cover on the Mack Daddy also protects the integrated spa and tanning ledge through the extended offseason, keeping water chemistry stable and debris out from October through May, and dramatically reducing the startup effort each spring.
What is the Mack Daddy's warranty?
Thursday Pools backs the Mack Daddy with a lifetime structural warranty on the fiberglass shell and a 15-year surface warranty on the gel coat finish. The structural warranty covers the entire shell, including the integrated spa, tanning ledge, and bench seating zones, against defects in materials and workmanship for the life of the pool. The surface warranty covers the gel coat throughout the pool against delamination and structural coating failure for 15 years. Ohio Paradise Pools adds over 32 years of Northeast Ohio installation experience, an A+ BBB rating, and three consecutive Cleveland swimming pool contractor of the year awards (2022, 2023, 2024) to that manufacturer coverage.
How does the Mack Daddy compare to building a primary pool plus a separate standalone spa?
Thursday Pools themselves positions the Mack Daddy as an all-in-one alternative to a pool-plus-spa installation. The integrated spa is molded into the Mack Daddy’s 16′ x 36′ shell, which means the total footprint of a pool with a built-in spa is contained within the Mack Daddy’s dimensions rather than expanded by the footprint of a separate Square, Round, or Grand Spa installation beside the pool. For homeowners who want both a pool and a spa and have a yard that accommodates a 16′ x 36′ footprint, the Mack Daddy consolidates both into one installation with one shell, one project scope, one warranty, and one cohesive design. The tradeoff is that the integrated spa cannot be repositioned or replaced independently the way a separately installed spa can.
How does the Mack Daddy compare to the Spirit, which also has a flat-bottom sport depth?
The Spirit and the Mack Daddy are both flat-bottom sport pool designs, but they differ significantly in what they provide beyond the swim lane. The Spirit (13.5′ x 40′) is a pure sport pool with full-length entry steps at both ends and bench seating at both ends, designed entirely around active family use across the full pool length. There is no integrated spa, no tanning ledge, and no dedicated conversation zone in the Spirit. The Mack Daddy (16′ x 36′) is the multi-zone design that adds an integrated spa with spillway, a 14-inch tanning ledge, and wraparound bench seating to a sport pool foundation. If your priority is active play across the full pool length without additional zones, the Spirit is the more focused design. If you want the sport pool depth paired with spa, lounge, and social zones all in one structure, the Mack Daddy is the design that was built for that combination.
