How much does it cost to install a vinyl swimming pool versus fiberglass pool?

Well first of all there is no such thing as a fiberglass pool. You can have fiberglass walls instead of steel but your pool is still vinyl because you need a liner. These are the usual combinations of inground pools.

1. Sand floor, steel walls, vinyl liner

2. Sand floor, fiberglass walls, vinyl liner

3. Vermiculite floor, steel walls, vinyl liner

4. Vermiculite floor, fiberglass walls, vinyl liner

5. Concrete floor, steel walls, vinyl liner

6. Concrete floor, fiberglass walls, vinyl liner

7. Concrete floor, concrete walls, no liner

Concrete pools have to be painted with epoxy paint or if you want tile installed then usually you plaster over the concrete.

Now a days 3 and 4 are the most common inground installs. 1 and 2 are usually pools that are 30 + years old although you can still have them done that way.

In South Alabama the cost of a 20 *40 vinyl pool will cost around 18 to 22 thousand
