How a coastal North Carolina beach resort retrofit a 1980s pool into a modern splash pad at Carolina Shores
A composite case study of an Outer Banks family resort converting an underused 50,000-gallon pool into a beach-themed splash pad — capital math, guest experience, and post-retrofit revenue impact.
Summary
An Outer Banks family resort converted a tired 1980s 50,000-gallon pool into a 5,000-square-foot beach-themed splash pad for $880,000, recovering the capital through an insurance premium reduction, eliminated lifeguard payroll, a measurable family-segment booking lift, and a year-round operating window. The retrofit is now the resort's most-photographed amenity and has become the template for two sister properties in the same hospitality group.
Key metrics
Background: an underused pool, mounting compliance costs, and a slipping family segment
Carolina Shores is a composite of mid-tier family resorts on the Outer Banks of North Carolina — a 78-room property with a small clubhouse, an oceanfront restaurant, and a 50,000-gallon outdoor pool built in 1984. By 2022, the pool had become a quiet line-item problem. Annual operating costs had climbed past $142,000 (driven heavily by chemistry, lifeguard payroll, and an aging filtration plant), the state health-department inspection regime had tightened in ways that consumed roughly 90 staff-hours per year of compliance time, and the property's family-segment bookings had been slipping versus competing properties that had added newer aquatic features. The general manager presented three options to ownership in the FY2023 capital cycle: refurbish the existing pool ($420,000), replace the pool with a larger zero-depth family pool ($1.3M), or retrofit the pool into a splash pad ($880,000). Ownership chose the splash pad path, citing the lower operating cost trajectory, the elimination of lifeguard payroll, and the year-round operating potential.
Capital math: not just the build cost
The $880,000 retrofit budget was the headline number, but the capital math worked because of three offsetting line items that the GM had to surface for ownership. First, the pool would have required roughly $420,000 in deferred-maintenance work over the next five years even with a refurbish-and-keep approach — so the marginal incremental cost of the splash-pad retrofit over staying-with-pool was closer to $460,000. Second, the property's commercial general liability carrier offered a $24,000 annual premium reduction once the pool was permanently decommissioned and replaced with a zero-depth pad (lifeguard-required pools sit in a higher actuarial bucket). Third, eliminating four seasonal lifeguard FTEs saved approximately $86,000 per year in fully-loaded labor costs. Stacked together, the payback period on the marginal incremental capital was roughly four years, which fit comfortably inside the property's 7-year capital-amortization framework.
Design choices: beach-themed and Instagram-conscious
The aquatic-design firm proposed a beach-and-marsh themed pad with three signature elements. First, a 'lighthouse' centerpiece — an 18-foot stylized concrete lighthouse with three water-jet decks that doubles as a photo backdrop. Second, a 'tide pool' zero-depth area at the toddler end with embedded fiberglass sea-life sculptures (turtles, fiddler crabs, starfish) that double as bench seating for parents. Third, a 'wave wall' interactive feature where guests can press a chrome button to trigger a two-second 30-gallon water sheet down a shaped concrete wall, with an audio cue that mimics a small ocean wave. The Instagram angle was deliberate — the GM had reviewed property review patterns and noticed that aquatic-amenity photos drove a disproportionate share of OTA conversion. The final design intentionally produced three distinct photogenic spots within the pad, each with a different time-of-day light profile.
Construction timeline: an off-season retrofit
The retrofit ran during the property's slow season — pool closed mid-October 2023, demolition and decommissioning ran through December (the existing 50,000-gallon vessel was structurally drained, the plumbing was capped, the deck was removed, and the basin was filled and re-poured as a slab), mechanical-building construction ran January–February 2024, feature installation ran March, and the pad opened on April 15, 2024 — three weeks before Memorial Day weekend, which is the Outer Banks' first major demand peak of the year. The off-season retrofit was critical to the financial case; running construction across an active summer season would have cost roughly $200,000 in lost room revenue, which would have flipped the project's payback math. The contractor's ability to commit to a hard April 15 opening date was a non-negotiable in the contract negotiation.
Opening reception: the photo wall and the off-season surprise
Opening weekend drew strong onsite engagement, but the property's marketing team was caught slightly off-guard by the off-season demand pull. The pad's year-round operating capability — possible because of the moderate Outer Banks winter climate and a heated mechanical building — meant that February and March 2025 were stronger family-segment months than they had ever been. The property added a 'shoulder-season splash weekend' marketing package in November, December, and February that bundled a discounted room rate with private 'pad hour' early-morning access; the package sold out for the first three weekends it was offered. Online reviews shifted measurably — the pad was mentioned in roughly 38% of post-stay reviews in summer 2024 (versus the pool's 14% mention rate in summer 2022), and 'splash pad' became a dominant search term in the property's owned-channel attribution data.
Operating costs and labor model
Year-one operating costs settled at approximately $58,000, broken down as $11,000 water and sewer, $6,000 chemistry, $13,000 electricity (year-round operation including heated mechanical building), $19,000 in pooled labor (the property's existing facilities-and-grounds team absorbed routine pad maintenance without adding headcount), $5,000 supplies and minor repairs, and $4,000 insurance allocation. Compared to the pool's $142,000 baseline, this represented an $84,000 annual savings even before the lifeguard-payroll elimination. The labor model is critical to replicability: a hospitality property with an existing facilities team can usually absorb pad maintenance into existing roles, while a standalone aquatic facility would need a dedicated attendant. The property did add a 'pad concierge' shift on summer weekend afternoons — a front-desk staff member rotating through the amenity area for soft hospitality presence (towel distribution, photo assistance, water-bottle hand-out), which guests rated highly in reviews.
Revenue impact: family-segment bookings and ADR
Year-over-year family-segment booking pace lifted approximately 18% in summer 2024 versus summer 2022 (the last full pre-construction comparable summer, since 2023 was disrupted by the off-season retrofit announcement). The property's average daily rate (ADR) for family-segment rooms also lifted roughly 6% in the same window, which the revenue management team attributed in part to the amenity differentiation. Total amenity-attributable incremental room revenue across the first 12 months post-opening was estimated at approximately $310,000, which combined with the operating-cost reduction and insurance reduction brought the actual payback period inside three years rather than the four-year underwriting case. Ownership has since approved the retrofit template for two sister properties in the same hospitality group, both targeted for off-season completion in the next two capital cycles.
Lessons learned and the off-season pad opportunity
Three lessons stood out. First, the year-round operating capability of a splash pad in a moderate coastal climate is a category-defining advantage over a pool — most coastal resort competitors are still seasonal, and a year-round pad creates a marketing wedge that compounds over time. Second, design the pad with three distinct photo backdrops rather than one centerpiece — the Instagram conversion compounds when guests can capture three different photos rather than one. Third, the lifeguard payroll elimination is real but needs to be communicated honestly to staff well in advance — the four lifeguard FTEs were given priority hiring consideration in adjacent property roles (front desk, food and beverage, facilities), and the property's hospitality reputation among local seasonal staff networks survived the transition cleanly. A poorly-handled lifeguard-elimination conversation could have damaged hiring for years.
Replicability for coastal and resort properties
The Carolina Shores model is highly replicable for coastal and resort properties in USDA Zones 8 and warmer with aging pool infrastructure. The single biggest replicability filter is climate — properties in colder climates lose the year-round operating advantage and the financial case becomes meaningfully tighter. The second filter is family-segment positioning — properties with primarily adult or business clientele will not see the same family-segment booking lift and may be better served by a different amenity refresh. The third filter is insurance carrier flexibility — not all commercial general liability carriers offer the same lifeguard-required-pool premium reduction, and the $24,000 annual savings should be confirmed with the actual carrier underwriting team before being included in the financial case.
Voices from the project
“The pool was a line item we kept defending in budget meetings. The pad is a line item we point to in marketing meetings.”
“Year-round operation flipped the entire family-segment calendar. February became a real month for us for the first time.”
“We re-hired three of our four lifeguards into other roles. The fourth retired. The story we tell our seasonal hiring network is that we take care of our people, and that mattered.”
Lessons learned
- Underwrite the retrofit against deferred pool maintenance, not against doing nothing.
- Confirm the insurance-premium reduction with your actual carrier before relying on it in financials.
- Design three distinct photo backdrops rather than one centerpiece feature.
- Run construction off-season; in-season retrofit costs swallow the project payback.
- Communicate lifeguard-elimination plans to staff well in advance and offer transition roles.
- Capture the year-round operating advantage in coastal/Sun Belt climates with shoulder-season packages.
- Track amenity mentions in post-stay reviews as a leading indicator of OTA conversion lift.
FAQ
How much does it cost to convert a pool into a splash pad?
Pool-to-pad retrofits typically run $700,000–$1.1M for a 4,000–5,500 square foot pad, depending on existing infrastructure, deck removal scope, and feature density. Carolina Shores landed at $880,000.
Will my insurance premium drop if I replace a pool with a splash pad?
Often yes — zero-depth pads sit in a lower actuarial risk bucket because they remove drowning risk and the lifeguard-required exposure. Confirm with your specific carrier before relying on the savings.
Can a splash pad operate year-round?
In moderate coastal and Sun Belt climates (USDA Zone 8+), yes, with a heated mechanical building and a careful drain-down protocol on cold snaps. Colder climates require a winterization shutdown.
