Pool Service Industry Fragmentation: Why No Company Owns More Than 10%

The pool service industry is one of the most fragmented sectors in home services. Despite a $62 billion total market, even the largest national players—Pool Corporation and Leslie's—hold less than 10% market share in their respective categories. The industry remains dominated by approximately 125,000 small, family-owned businesses.

The Scale of Fragmentation

Pool Corporation, the industry's largest wholesale distributor, serves approximately 125,000 professional customers—the vast majority being small, family-owned independent contractors.[1]Pool Corporation 10-KFiscal year ended December 31, 2024SEC Filing

Most of these businesses operate with no more than 10 employees; many are "one-man-and-a-truck" operations. This structure has remained remarkably stable even as the industry has grown.

Market Share Reality

Even the industry giants command surprisingly modest market shares. Pool Corporation reported $5.3 billion in 2024 net sales within a total industry valued at $62 billion by the Pool & Hot Tub Alliance—representing just 8.5% of the total market.[3]Pool Corp Q4 2025 Earnings CallFebruary 2026Transcript[4]PHTA Industry Revenue Report2025 Press ReleasePHTA Website

The chart below visualizes this market share reality—even the largest players command less than 10% of their respective markets, leaving the vast majority of industry activity distributed among thousands of smaller operators.

The Independent Advantage

Leslie's operates 1,021 branded retail locations—making it the largest national specialty pool care retailer.[2]Leslie's, Inc. 10-KFiscal year ended September 28, 2024SEC Filing Yet independent retailers still outnumber Leslie's stores by nearly 8 to 1.

This means there are approximately 7.8 independent pool retail locations for every 1 Leslie's store—a ratio that has remained relatively stable over the past decade.

Why Fragmentation Persists

Several structural factors explain why the pool service industry has resisted consolidation:

1. Local Relationship Model

Pool service is inherently local. Customers prefer dealing with technicians they know and trust, who understand their specific pool and equipment. This relationship-driven model makes it difficult for national chains to replicate the service quality of established local operators.

2. Low Barriers to Entry

Starting a pool service business requires relatively modest capital investment—often just a truck, basic equipment, and chemicals. The low startup costs enable constant new market entry, maintaining competitive pressure.

3. Route Economics

Pool routes have natural geographic boundaries based on drive time efficiency. A single technician can typically service 12-18 pools per day within a tight geographic area. Expansion beyond these boundaries requires adding trucks and technicians, which replicates the small-business model rather than achieving economies of scale.

4. Labor Intensity

Unlike product distribution (Pool Corp) or retail (Leslie's), pool service cannot be easily automated or centralized. Each pool requires physical on-site work, limiting the scalability advantages that drive consolidation in other industries.

Wholesale Support Density

Pool Corporation operates 456 sales centers across the country, serving those 125,000 professional customers. This translates to approximately 274 service/retail businesses per wholesale location.[3]Pool Corp Q4 2025 Earnings CallFebruary 2026Transcript

PHTA Membership Context

The Pool & Hot Tub Alliance reports approximately 4,000 member organizations worldwide.[4]PHTA Industry Revenue Report2025 Press ReleasePHTA Website This represents just 3.2% of the estimated 125,000 professional businesses—suggesting the vast majority of pool service operators remain unaffiliated with the industry's primary trade association.

What This Means for Pool Service Businesses

The fragmented market structure creates both challenges and opportunities:

• Opportunity: Small operators can compete effectively against national players through superior local service and relationships
• Challenge: Limited buying power compared to larger competitors—though chemical pricing strategies can help
• Opportunity: Technology can help small operators achieve efficiency gains without losing their local advantage
• Challenge: Recruiting and retention remain difficult when competing with larger employers for talent
