Best fiberglass pool shapes for families

Less than the depth profile, more than most people expect. Shape decides how the pool sits in the yard and how easily it takes a cover. The depth profile, meaning how much of the pool is standing depth, where it slopes and how deep it gets, decides who can actually use it. With fiberglass both are molded into the shell, so they are fixed once you choose a model.

The usual advice about pool shape leans on looks: rectangles feel modern, freeforms feel natural. That is fair, but a family should start somewhere else. Think about who is in the water on a typical July evening, what they do there and who is watching from the deck. The shape that suits that picture is the right one, and it may not be the one in the prettiest photo.

Liberty Composites, whose shells we install, groups its designs into rectangular, freeform and kidney shapes, plus a set of compact plunge pools.

• Rectangles give the most usable water for the footprint. Liberty describes the Anthem as having a bench entry, a 30 foot swim lane, an end-to-end tanning ledge and exits on both sides. Rectangles line up cleanly with a patio or house wall and take an automatic cover in straight tracks.
• Freeforms trade a little water for curves and built-in seating. The Hero, 12 by 26 feet, has multiple entries, swim-up seating and a tanning ledge. The Devotion is a large freeform at 16 by 40 feet, 3 feet 6 inches to 6 feet 6 inches deep, holding about 17,000 gallons.
• Kidney shapes are the classic curve, often with seating on the inside bend. The Dignity, just under 10 by 20 feet, has swim-up seating and a wading area, and the Merit is a larger kidney at about 14 by 27 feet.

Shallow water with a clear edge. A wading area is the feature to look for. Liberty describes wading areas as similar to tanning ledges but with more water, roughly 14 to 18 inches deep, which is enough for a small child to sit and splash under close watch. The Dignity and the Virtue both include one. Wide, textured entry steps help too, and Liberty's option list includes safety ledges, slim ledges below the waterline that give a child learning to swim a place to hold on and rest.

No shape makes a pool safe for toddlers on its own. The U.S. Consumer Product Safety Commission reports 379 fatal child drownings in pools and spas in 2023, with more than 70 percent of fatal drownings between 2021 and 2023 happening at homes. It recommends a designated adult water watcher who is not on a phone, plus barriers and alarms. Design helps by making supervision easy: put the shallow end nearest the house, keep sight lines from the patio open and choose steps where a parent can sit in the water beside a child.

Kids from about six to twelve mostly want room to throw a ball, race across and play games in water where they can touch bottom. That favors a long, fairly flat shallow area at around 3 feet 6 inches that slopes gradually to a deeper section. Rectangles do this well. The Hero and Victory freeforms do it in a smaller footprint.

Resist the pull toward the deepest shell you can afford. A deep end that nobody can stand in turns a big pool into a small one for this age group. Liberty pools are non-diving, so an 8 foot deep end does not buy you a diving board either.

Teenagers use length and depth. A 16 by 38 or 16 by 40 foot pool gives enough room for friends to spread out and enough deep water to feel like a real pool. The Heavenly 16 is 15 feet 10 inches by 38 feet with a deep end of 6 feet 8 inches and a tanning ledge with integrated swim-up seating. The Virtuous is 16 by 40 feet and goes to 8 feet deep. Liberty's Valiant is a narrower option at 14 by 31 feet 6 inches, running from 3 feet 7 inches to 7 feet.

If you are buying for the family you will have in five years, weigh that against the family you have now. A pool with a big shallow end and a moderate deep end works across more ages than one built only for teens.

Easy entry matters more than anything else. Look for wide steps that run the full width of one end, a bench you can sit on in the water and a second way out on the far side. Liberty's Stature 13.23 has full-width entry steps with built-in swim-up seating, and the Anthem's bench entry and two-sided exits serve the same purpose. Textured, slip-resistant steps are standard on Liberty shells. A handrail at the steps is worth adding if anyone in the family needs one.

Swim-up seating, a molded bench along one wall, is also the feature adults use most in any family pool. It is where people talk while the kids play, and in a short Ohio season that time adds up.

Two ways. First, water warms faster when there is less of it under the same surface. A pool with a large shallow area heats up quicker in the sun and with a heater than one with a deep end that holds a lot of cold water. In a place where the swim season runs roughly Memorial Day to Labor Day without help, that makes a shallow-heavy profile feel warmer, sooner.

Second, covers. An automatic cover keeps heat in overnight, keeps leaves out and adds a layer of protection against a child getting into the water. Automatic covers work most simply on rectangles. Liberty flags many of its models as auto cover ready, including the Anthem, Valiant, Glory and Heavenly 16. If a cover is on your list, and in Ohio it should be, choose a model that takes one without extra work.

A tanning ledge is a shallow shelf, usually around 10 inches of water on Liberty's add-on ledges, that works as a lounge spot for adults and a splash zone for small children. Many Liberty models have one molded in, including the Anthem, Hero and Heavenly 16. For families it often does double duty: parents sit in a few inches of water with a drink while a toddler plays beside them, under direct watch.

Built-in spas show up on the Deluxe versions of several models, such as the Hero Deluxe and Relaxation Deluxe. A spa lengthens the season on both ends, because a small body of hot water is comfortable long after the main pool feels cold. With children, treat the spa as its own safety zone. Hot water is not a place for toddlers, and the CPSC recommends keeping spa water at 104 degrees Fahrenheit or below for anyone.

Either feature takes some water area away from swimming and play in exchange for sitting space. For a young family that trade is usually worth it. For a family of strong teenage swimmers, less so.

Our published packages for family sizes include the Hero 12x26 at $74,900, the Anthem 14x30 at $90,200, the Devotion 16x40 at $97,500 and the Heavenly 16x38 at $101,300.

The fence, extra patio, spoils haul-off, any dewatering and the power run from your panel are priced after the site visit because they depend on the yard. Financing is available through lenders we work with, including PoolLoan.net and HFS Financial.

Put both on your lot in 3D and look at them from the back door. We design every pool that way before anything is dug. Then ask three questions. Where will the adults sit while the kids swim, and can they see the whole pool from there? How much of the water can your shortest swimmer stand in? And will the cover you want fit the shape without a custom track? The model that answers all three well is usually the right family pool.
