Fiberglass pool brands compared: Liberty, Latham, Leisure, River

Start shopping for a fiberglass pool and a handful of names come up again and again. Everything below comes from each manufacturer's own website or published warranty, not from dealer claims or forum posts. Where a manufacturer describes itself in marketing terms, we say so.

One thing they all share: none of these companies installs pools for homeowners. Each builds shells in a factory and sells them through independent dealers, builders or franchisees who handle the dig, the set and everything after. That shapes how you should compare them, and we come back to it at the end.

Liberty is the brand we install. Its 2025 warranty document describes Liberty Pool as a branded product line of Latham Pool Products, Inc., and the Liberty website notes that its pools are manufactured by Latham. The shells use Latham's Crystite gelcoat.

The lineup runs from the 9 by 17 ft Enrichment to 16 by 40 ft shells like the Devotion and Virtuous, including Deluxe models with a spa molded into the shell. Liberty lists every model as non-diving unless stated otherwise and notes dimensions can vary up to 3 percent.

Liberty's marketing calls its coverage a limited lifetime warranty. The written 2025 warranty covers the shell against leaking due to structural failure from manufacturing defects for 25 years and the gelcoat against osmotic blistering for 20 years, on conditions that include keeping the pool full of water and maintaining the water chemistry the owner's manual calls for. We explain it clause by clause in our Liberty warranty guide.

Latham sells fiberglass pools under its own name as well as through the Liberty line, along with vinyl liner pools, liners and covers. The company says it has more than 70 years of history and describes itself as the largest manufacturer of pools in North America. Its fiberglass pools use its proprietary Crystite gelcoat and what it calls Advanced Composite Technology, which it says resists fading, stains and scratches.

Latham advertises industry-leading limited lifetime warranties on its fiberglass pools, and says a fiberglass pool can last 50 to 60 or more years with proper care. As with any brand, the written warranty that comes with a specific pool sets the actual terms. We install Latham vinyl liners, including its UltraSeam liner technology, on our vinyl liner pools.

Leisure Pools USA says more than 150,000 of its pools have been installed. Its shells are built around what it calls a patented Composite Armour Core of Strength, which embeds carbon fibers in vinyl ester resin reinforced fiberglass. Leisure states that it uses vinyl ester resin throughout the laminate rather than as a single barrier layer, and explains that vinyl ester bonds layers well and resists the water absorption that leads to osmosis.

The gelcoat is Aquaguard X, which Leisure imports from the coatings company Allnex, and Leisure states each pool's gelcoat is covered by a 10 year gelcoat warranty. Its site advertises lifetime warranties overall. Leisure notes its dealers are independently owned and operate under a license from the company.

River Pools manufactures fiberglass shells and, in its own words, does not install pools. Shells are installed by locally owned dealers and franchisees. River describes its build as a vinyl ester resin barrier coat behind the gelcoat, followed by chopped fiberglass, hand-laid woven roving, stitch matting and honeycomb core in areas like sidewalls, steps and benches, all laid up indoors with molds kept level.

River also publishes a great deal of consumer education on fiberglass pools, and its site notes that some of that content is years old and that buyers should confirm specifications with their installer.

Thursday Pools started in 2010 and builds its shells in a 150,000 square foot climate-controlled plant on 100 acres in Fortville, Indiana. Its lineup includes multi-level designs and a walk-in beach entry, which it describes as one of a kind. Like the others, it sells through independent dealers. Thursday notes that its listed dimensions can vary by about 2 to 3 percent and that the delivered shell governs.

San Juan says it has been building fiberglass pools since 1958, starting as a small Washington-based company and growing into a group of manufacturing plants across the U.S., each with its own network of independent authorized dealers. The warranty is issued by the specific San Juan plant that made the pool.

San Juan's published warranty covers the shell for 25 years from installation against leaking caused by structural failure from manufacturing defects. It is non-transferable, applying only to the original retail buyer. The same document states that the gelcoat is a cosmetic finish and is not warranted against cracking, bubbling, discoloring or fading, and it requires the registration card to be returned within 10 days of purchase.

The gelcoat is the colored outer layer you see and touch, and every brand has its own. Latham's Crystite line includes finishes with shimmer embedded under a smooth surface, which Latham says resists fading from wear, chemicals and UV. Leisure markets its Aquaguard X colors for their sparkle and for UV, blister and chemical resistance. Liberty uses Latham's Crystite gelcoat, and you choose the color from its collection.

Two practical points apply to every brand. First, color reads differently under Northeast Ohio's softer, often cloudy light than it does in a sunny catalog photo, so look at real installed pools or large samples before you decide. Second, a finish with several layers or embedded shimmer can be harder to match if a spot ever needs repair. Ask the installer how a gelcoat repair would be color matched on the finish you pick.

Finish coverage is also where warranties differ the most. Some cover osmotic blistering in the gelcoat for years, some for a shorter term, and some treat the gelcoat as cosmetic and leave it out. Both the Liberty and San Juan documents exclude ordinary fading and discoloration, so read how any warranty treats a finish that changes color over time. Good water chemistry does more to keep a gelcoat looking new than any warranty clause.

Brochures from every maker talk about strength and beauty. The useful comparisons are more specific:

• The written warranty. Read the document, not the headline. Check how long the structure is covered, whether the gelcoat finish is covered against osmotic blistering and for how long, whether the warranty transfers to the next owner, the registration deadline, and who pays to drain and brace the pool during a repair. Liberty's 2025 warranty, for example, puts draining, bracing and groundwater removal on the buyer.
• The resin. Several makers describe vinyl ester resin as a barrier or throughout the laminate to resist water absorption and blistering. Ask what is used where.
• The models. Every brand has shells that fit some yards better than others. Width, depth, steps, benches and ledges matter more than the brand name for how you will use the pool.
• The installer. Every warranty above requires proper installation. Liberty's excludes failures caused by installation that does not follow codes, the industry standard for residential inground pools, the owner's manual and the maker's procedures.

Because the manufacturer builds the shell, and the installer builds everything that keeps it level, dry and leak-free. Liberty's warranty is blunt about it: Latham does not warrant the installation and disclaims responsibility for damage caused by improper storage, transportation or installation by a dealer.

In Northeast Ohio that point carries extra weight. Our clay soils hold water, and seasonal groundwater sits close to the surface in much of the region. A shell set on a poor base, backfilled with the wrong material or left without a way to relieve groundwater pressure can move no matter whose logo is on it. Ask any installer how they handle the base, backfill and groundwater, and how long they have been setting shells in this ground.

It is the fiberglass line we have chosen to build around. The range covers what Northeast Ohio families ask for, from a 9 ft wide Enrichment to a 16 by 40 ft Virtuous, with Deluxe spa models in between. The shells come from Latham, a large, long-established manufacturer. The written warranty is clear about its terms. And because we install one brand, we know every model's layout, depths and quirks, which helps when we design your pool in 3D on your lot. Our installed Liberty packages run from $68,400 to $103,900.
