Wide entry steps and built-in benches on both ends encourage gathering and conversation, while the center swim lane leaves plenty of space for laps, games, or a peaceful float. With its blend of beauty and practicality, Titus is a popular pick for families who want both fun and function in a medium-sized pool.

How Your Pennsylvania Property Can Influence Your Pool Installation Costs
Before breaking ground on your dream pool, you should be aware of how your Pennsylvania yard’s natural characteristics could affect installation. The Keystone State’s diverse terrain includes everything from rocky Appalachian foothills to soft river valley soil—and what’s underground matters just as much as what’s above.
In regions like the Poconos or Western Pennsylvania, rocky soil may require more intensive excavation efforts, adding time and labor to the project. Heavy-clay soil pockets around Central Pennsylvania and parts of the Lehigh Valley can complicate drainage and demand more site preparation. Meanwhile, properties near the Susquehanna River or Delaware Valley may feature looser, sandy soil that needs reinforcement to ensure the fiberglass pool shell’s long-term stability.
Sloped lots are typical in regions like the Lehigh Valley and along the Allegheny Plateau and may require additional grading. Older neighborhoods in cities like Harrisburg or Scranton may present access challenges for large equipment, impacting installation logistics.
Topography is another key consideration. Sloped yards in the Lehigh Valley, along the Allegheny Plateau, and in hillside communities near Reading or Altoona might need extensive grading or retaining walls to provide a flat, safe surface for your shell and surrounding pool deck.
Accessibility also plays a significant role in both planning and cost. Older neighborhoods in cities like Harrisburg or Scranton may present access challenges for large equipment, impacting installation logistics. In densely populated areas, narrow sideyards, tight lot lines, or overhead utility lines may make transporting and positioning a one-piece fiberglass pool shell difficult. In some cases, a crane rental or other specialty equipment may be necessary. Local permitting rules, HOA guidelines, and township-level zoning ordinances—often stricter in historic and densely developed areas—can also affect your timeline and budget.

Fencing, Safety, and Pennsylvania’s Pool Rules: What You Need to Know Before You Make a Splash
Installing a fiberglass pool in Pennsylvania requires understanding and exceeding local legal regulations or building codes regarding safety barriers. The Keystone State enforces residential pool safety through its adoption of the Building Officials and Code Administrators (BOCA) National Building Code and the International Swimming Pool and Spa Code (ISPSC), both of which set minimum requirements for fences, gates, and other protective barriers. These codes apply statewide to prevent pool accidents or unauthorized access by children and pets.
Under Pennsylvania regulations, a barrier at least 48 inches high must surround any pool deeper than 24 inches. The barrier must not have any openings large enough to allow a 4-inch sphere to pass through, and any gates must be self-closing, self-latching, and open outward away from the pool. If the latch is less than 54 inches above the ground, it must be on the pool-facing side of the gate.
Local municipalities across Pennsylvania often have their own building codes, permit requirements, and barrier regulations that build on these baseline rules. In Philadelphia, for example, residential pools must be in the rear yard and follow strict setback and fencing requirements.
Failing to follow these requirements can result in fines or delays in getting your pool up and running. To avoid surprises, check in with your local municipality, HOA, or a knowledgeable pool professional who understands the applicable laws and codes specific to your area.
Costs vary with layout and materials, but Pennsylvania homeowners pay an average of $11,028 for a 300-linear-foot fence, according to our dealer survey.

Not all fiberglass pool models are suitable for diving or slide use. It is the responsibility of the homeowner and installer to ensure proper installation and usage.
