We’ve covered plenty of swimming pool Top 10’s in Pool Magazine, including the world’s most expensive pools. Today, however, we’re going to be looking at some of the largest pools on Earth. With that said, let’s dive right in!

City Stars Sharm El Sheikh – Largest Swimming Pool in the World

At 23.9 acres City Stars Sharm El Sheikh by Crystal Lagoons; is officially the largest swimming pool project in the world.

In conclusion:

You may have asked the question “what is the largest swimming pool in the world” and gotten 100 different answers. Unfortunately, there is a lot of conflicting information out there and statistics have a tendency to be copied & pasted without much fact-checking these days. Stats also have a way of changing quicker than human beings tend to update their websites.

In fact, the Guinness Book of World Records even still lists the 8.9-acre Orthlieb Pool in Casablanca, Morocco as the largest pool on the planet. Unfortunately, that pool was demolished back in 1986 and hasn’t been around for quite some time. There are also plenty of places that still list the San Alfonso Del Mar as the world’s largest swimming pool, but it was supplanted back in 2015 by the #1 pool on our list. City Stars Sharm El Sheikh is officially the largest swimming pool on the planet – for now.

Blue Wave Recall on Over 13,000 Above Ground Pools

Published

on

Blue Wave Above Ground Pool Product Recall

Blue Wave has issued a recall affecting multiple above-ground swimming pool models after federal safety officials identified a potential drowning hazard involving children.

The recall, announced by the U.S. Consumer Product Safety Commission (CPSC) on December 18, covers approximately 13,400 Blue Wave brand above-ground pools that are 48 inches deep or taller and utilize an exterior compression strap as part of the pool’s frame system.

Reason for the Recall

The affected pools feature a compression strap positioned around the outside of the vertical support poles. While the strap is designed to provide structural stability, the CPSC determined that its placement may unintentionally create a foothold.

According to the agency, this foothold could allow children to climb into the pool, even when the ladder has been removed, creating a risk of unsupervised access and potential drowning.

No injuries or fatalities have been reported in connection with the recalled products at the time of the announcement.

Affected Models

The recall applies to the following Blue Wave above-ground pool models:

• Blue Wave 15-Ft Rd 48-In Active Frame Pool
• Blue Wave 18-Ft Rd 52-In Active Frame Pool
• Blue Wave 18-Ft Rd 52-In Dark Cocoa Wicker Frame Pool
• Blue Wave 24-Ft Rd 52-In Dark Cocoa Wicker Frame Pool
• Blue Wave Rustic Cedar 15-Ft Round 48-In Deep Frame Swimming Pool Package W/Cover
• Blue Wave Rustic Cedar 18-Ft Round 52-In Deep Frame Swimming Pool Package W/Cover
• Blue Wave 18-Ft Round 52-In Gray Rattan Swimming Pool Package W/Cover
• Blue Wave 18-Ft Round 52-In Espresso Wicker Swimming Pool Package W/Cover
• Blue Wave 15-Ft Round 48-In Navy Blue Frame Swimming Pool Package W/Cover
• Blue Wave 18-Ft Round 52-In Navy Blue Frame Swimming Pool Package W/Cover
• Blue Wave 15-Ft Round 48-In Aspen Swimming Pool Package W/Cover
• Blue Wave Mocha Wicker 18-Ft Round 52-In Deep Swimming Pool Package With Cover
• Blue Wave Mocha Wicker 24-Ft Round 52-In Deep Swimming Pool Package With Cover
• Blue Wave Laguna 15-Ft Round 48-In Deep Swimming Pool Package With Cover
• Blue Wave Laguna 18-Ft Round 52-In Deep Swimming Pool Package With Cover

All affected models share a common design feature: an exterior compression strap that encircles the pool’s vertical supports.

Sales Channels and Distribution

The recalled pools were sold nationwide from January 2021 through July 2025 through a mix of big-box retailers, sporting goods stores, and online marketplaces, including:

• The Home Depot
• Lowe’s
• Dunham’s Sports
• Amazon
• Walmart
• Wayfair

Retailers have been notified to halt sales of affected models and to direct customers to the manufacturer’s recall remedy.

What Dealers and Retailers Should Know

For dealers and retail partners, the recall highlights the importance of prompt inventory review and customer outreach. Any remaining unsold stock matching the recalled models should be removed from the sales floor and distribution channels immediately.

Retailers that sold affected units during the recall period may see an increase in customer inquiries regarding eligibility, repair kits, and interim safety measures. Clear communication at the point of contact will be critical, particularly around the distinction between structural components and ladders, which many consumers assume are the primary access risk.

Service professionals and retail staff should also be prepared to explain that the recall does not involve a full product replacement, but rather a manufacturer-provided modification designed to eliminate the foothold while maintaining frame integrity.

Manufacturer Remedy

Blue Wave is offering a free repair kit to affected pool owners. The kit replaces the exterior compression strap with a lower-profile system installed closer to ground level. Once the repair is completed, the original strap can be removed.

Until the repair is installed, the manufacturer and CPSC recommend that pool owners prevent unsupervised access to the pool area or drain the pool temporarily.

Dealers and service professionals should advise customers not to remove or cut the compression strap prior to installing the repair kit, as doing so could compromise the pool’s structural stability.

Latham Group Appoints Sean Gadd as Chief Executive Officer

Latham Group, Inc. (Nasdaq: SWIM), the largest designer, manufacturer, and marketer of in-ground residential swimming pools in North America, Australia, and New Zealand, appoints Sean Gadd as the company’s new President and Chief Executive Officer as part of a CEO transition that will take effect on January 5, 2026. The appointment follows a comprehensive search as part of a succession planning process led by the Board and current CEO Scott Rajeski, who will be retiring from Latham and will serve as a special advisor to the company.

Sean Gadd comes to Latham following a 21-year career at James Hardie. He most recently served as President of North America since 2022, where he has had full P&L responsibility for James Hardie’s largest regional business. Prior to his role as President of North America, Sean served as Executive Vice President, North America, Commercial (2018-2022) and Executive Vice President, Markets and Segments, North America (2015-2018) at James Hardie, leading the front end of the business across product, marketing, and sales. Sean has been instrumental in spearheading James Hardie’s substantial organic net sales growth since 2022, driving material conversion and deeper market penetration through a refined go-to-market strategy targeting end-users via channel partners. Sean brings experience that is directly comparable to Latham’s material conversion and Sand State initiatives, and his demonstrated success in driving strategic growth will be invaluable for Latham and its shareholders.

James E. Cline, Chairman, commented, “Sean is known as a strong leader and brand-builder and has an impressive track record of driving growth at James Hardie. We are thrilled that he has accepted the CEO role at Latham, and the Board believes Sean will be able to leverage his robust commercial experience, sector knowledge, and branding expertise to accelerate our ability to continue to gain share and further the conversion to fiberglass from concrete pools.”

“I am pleased to be joining Latham and am looking forward to building on its achievements to date. This is an excellent opportunity for me to utilize my experience in the building products category to drive further market penetration and adoption of Latham’s top-quality products and greater recognition for its superior service standards,” Mr. Gadd commented.

Mr. Gadd will also become a member of Latham’s Board of Directors, replacing Mr. Rajeski, who is resigning from the Board concurrently with his retirement.

Mr. Cline commented, “On behalf of the Board of Directors, I want to express our deep appreciation for the contributions that Scott Rajeski has made to Latham during his long tenure at the company, first as Chief Financial Officer and, since 2017, as President and Chief Executive Officer. Under his leadership and that of his executive and operating teams, the company went public in April of 2021 and has experienced substantial growth, demonstrated resilience within a difficult industry environment, and built a strong financial position.”

Mr. Rajeski noted, “It has been a privilege to serve as the President & CEO of Latham alongside the talented executive and operating teams that we have at the company. Together, we have advanced the awareness and adoption of fiberglass pools and autocovers, while implementing production and related efficiencies that have streamlined our operations. I am proud to be retiring as CEO of Latham with the company in a strong financial position and in very capable hands. Throughout my conversations with Sean, I have been very impressed with his leadership capabilities and background, and I am confident that he will bring a unique skillset that will allow Latham to continue to outperform the industry, gain further traction in the important Sand States, and remain an acquirer of choice.”

About Latham Group, Inc.

Latham Group, Inc., headquartered in Latham, NY, is the largest designer, manufacturer, and marketer of in-ground residential swimming pools in North America, Australia, and New Zealand. Latham has a coast-to-coast operations platform consisting of approximately 1,850 employees across around 30 locations.
