Concrete, Vinyl or Fiberglass Pool? How to Choose a Shell

Each type of pool shell has a personality, and the best one depends on your yard, your plans and how long you'll stay.

Concrete, Vinyl or Fiberglass Pool? How to Choose a Shell

If you ask ten pool owners which type of pool is best, you'll get ten confident answers, and most will describe the one they happen to own. The honest answer is that it depends. Admiral Pools builds all three kinds, concrete, vinyl and fiberglass, so we have no reason to push you toward one.

What we can do is lay out how they differ, so you walk into the conversation knowing which questions matter.

Vinyl: a liner over a built frame

A vinyl pool is built from a frame of walls with a custom-cut vinyl liner stretched inside. The liner is what holds the water and gives the pool its color and pattern. Because the walls are assembled to your dimensions, vinyl is flexible about shape and size, and it tends to be the quickest of the three to bring online.

The tradeoff is that the liner is a wear item. Sunlight, chemistry and years of use eventually mean a replacement, so it helps to think of that as part of the long-term picture. The surface is smooth and comfortable underfoot, which many families like.

Fiberglass: a pool that arrives as one shell

A fiberglass pool is manufactured off site as a single shell, then lifted into a hole prepared for it. Because the shell is made in a factory, the shapes come from a catalog of designs. You choose from what exists rather than drawing something from scratch.

That also means your yard has to accommodate the whole shell, including a path for it to get to the hole. The surface is smooth and the installation is typically fast, since the shape arrives finished.

Concrete: shaped on your lot

A concrete pool is formed and finished on site, which is why it's the most customizable. Odd shapes, built-in benches, sunshelves, spas that spill over, steps that wrap a corner: if you can describe it, concrete can usually make it. The interior is finished with plaster, in white or in upgraded options like quartz or pebble.

That freedom comes with a longer build, and the surface will want attention over the years. When a concrete pool gets tired, re-plastering brings it back, and we'll cover that in another article.

Cost and timing, in plain terms

Cost is the question everyone asks first, and there's no single answer. Many variables go into the price of a pool. To give you a sense of the range, a small vinyl pool can start in the lower 20,000s, while other pools can be well over $100,000. The spread between those two numbers is the combination of size, shape, features, deck and the shell you choose.

Timing varies just as much. Vinyl and fiberglass pools take a considerably shorter time to complete than concrete, and they can be finished in as quickly as a week in some circumstances. Weather and your contractor's schedule play a big part, so treat any quick number as the best case rather than a promise.

What each one asks of your yard

  • Vinyl: a lot of design freedom, so it adapts well to odd lots, though you'll need room and access for the excavation
  • Fiberglass: space for the full shell to be delivered and set, and a design that fits within the available shells
  • Concrete: room for forms and equipment, and patience for a longer build in exchange for a pool shaped around you

Slope, a high water table, tight access past the house and mature trees can all change which option makes sense. That's why the lot walk comes before the decision. If you're still checking whether a pool fits at all, read our piece on plot plans, setbacks and septic systems first.

How long will you stay, and what will you use it for?

Two questions we ask every family: how long do you plan to stay in this home, and what do you want the pool to do? Lap swimmers, kids who live in the water, and people who mostly want a place to sit with a drink and a view are all building different pools.

There's also the matter of long-term care. Every pool needs preventative maintenance, and each type has its own habits. A liner gets replaced, plaster gets refreshed, and a fiberglass surface has its own routine. Ask what upkeep looks like at year ten, not just at the ribbon cutting.

The right pool is different for everyone, and a builder who only works in one material will naturally lean that way.
