A factory-molded shell with a smooth gel coat, selected from available shapes and placed after site preparation. Scheduling depends on access, permits, weather, decking, and site work.

A factory-molded shell with a smooth gel coat, available in defined shapes and placed after the site is prepared.
A fiberglass pool is a one-piece shell, molded in a factory and finished with a smooth gel coat before it ever reaches your property. We excavate, set the shell on a prepared base, plumb it, and build the surround. Tri-Star State Pools offers shell options from Imagine Pools and Latham.
Because the pool arrives already built, the project looks nothing like a concrete build. The shell is delivered to the property and craned into the prepared excavation. That one difference drives most of what makes fiberglass worth considering.
A gunite pool is built in place through several shell and finish stages. A fiberglass shell arrives already molded and gel-coated, so shell placement has fewer on-site stages. The complete project schedule still depends on access, excavation, permitting, weather, utilities, decking, and startup.
Gel coat provides a smooth, non-porous interior surface. Water chemistry, cleaning, and equipment care still matter, and the manufacturer supplies the care requirements for the selected shell.
Fiberglass does not use a plaster interior or a replaceable vinyl liner. Owners still balance water, clean the pool, maintain equipment, and follow manufacturer guidance for the gel coat and any repairs.
Middle Tennessee freeze-and-thaw conditions affect plumbing, equipment, drainage, backfill, and seasonal care. The site plan and winterization approach should follow the shell manufacturer's requirements and the conditions of the property.
Manufacturer coverage varies by shell and product. Review the written terms, exclusions, registration steps, water-chemistry requirements, and which party handles a future claim before choosing a model.
Tanning ledges, benches, and steps are molded into the shell at the factory, so the places you actually lounge arrive finished in the same smooth gel coat as the rest of the pool.
Every fiberglass shell starts in a manufacturer's catalog of available shapes and sizes. The shell choice sets the basic outline, steps, benches, ledges, depths, and gel-coat options before excavation begins.
If your plan calls for an outline or dimensions outside those molds, gunite may offer more flexibility. Explore gunite pools on their own page and compare the construction sequence as well as the shape.
We do not publish hard prices because the pool is only one part of the scope. Access for equipment, excavation, grading, drainage, the shell, utilities, equipment, decking, barriers, and site restoration all affect a proposal. The planning guide explains what information to gather before a site conversation.
We review the yard, choose a shell, confirm the permitting path and site constraints, then plan excavation and grading for the selected model.
Your one-piece shell is molded and gel-coated at the factory, then trucked to the site and craned into the excavation in a single lift.
The shell is set, plumbed, and backfilled according to the project specifications. Decking, equipment startup, inspections, and handover follow as the written scope requires.
Tri-Star State Pools project photos are shown as general design references. Their placement on this page does not identify a construction type.
Shell placement is one stage of the work, not the full backyard schedule. Access, excavation, weather, permitting, utilities, inspections, decking, drainage, equipment startup, and restoration all affect the completion date. A proposal should state what the schedule covers and which dependencies can move it.
Service life depends on the selected shell, installation, drainage, water chemistry, maintenance, environment, and manufacturer requirements. Review the specific written warranty and care documentation rather than relying on a single lifespan claim.
The smooth gel coat creates a different cleaning surface than plaster or vinyl. You still balance water, clean the interior, maintain equipment, and follow the manufacturer's chemistry limits. Ask what recurring care and possible repairs are included in the ownership plan.
Within the manufacturer's catalog, yes: lengths, depths, tanning ledges, steps, benches, and finish colors. Shells travel by highway, so width tops out at what a truck can carry. And if a one-of-a-kind outline is the dream, that is exactly what our gunite builds are for.
The shell, backfill, drainage, plumbing, equipment, and water level all need a climate-appropriate plan. Ask how the selected manufacturer's instructions apply to your property and what winterization or cold-weather monitoring the written handover requires.
The contractor credential above is held by Tennessee Home Builders and is not presented as a Tri-Star State Pools license. The contracting and permitting parties belong in the written proposal.
