How Deep Can Preformed Inground Pools Be?

Size and Depth Restrictions

• Fiberglass swimming pools must be ordered and trucked in by a manufacturer, so they are limited to transport and production restrictions. Generally, these swimming pools are no deeper than 8 feet and no wider than 16 feet. Many are as shallow as 5 feet and are not appropriate for diving. But if you decide to purchase an inground vinyl pool liner, you can request a depth greater than 8 feet. Vinyl liners are manufactured to your specifications. Both types of preformed pools can be constructed to be quite long, as much as 40 feet or more, and can look and function just like real pools.

Styles

• There are a variety of styles to choose from when ordering a fiberglass or vinyl pool. A standard rectangular shape, with various depth options, is a classic look. Odd shapes, such as kidney shapes or those with wavy and curved edges, offer an interesting appearance and can sometimes help you to better fit your pool within the size restrictions of your yard. With a fiberglass pool, you are limited to manufacturer designs. But with a vinyl liner, you can create your own design and shape.

Advantages

• Recent advances in fiberglass pool design allow for an aesthetic appearance that looks closely like a real inground pool. Color finishes and new design techniques allow for fiberglass pools that look sophisticated rather than tacky. They last longer than vinyl pools. Vinyl liners are smooth on the feet and the cheapest type of pool installation you can find. But they will probably need multiple replacements and are less cost efficient over time. In any case, preformed pools are also easy to install, without the need for pouring concrete.

Installation

• Select a preformed inground pool that fits in with your existing landscape. Based on the shape you choose, you should designate areas for swimmer traffic to prevent a crowded yard. Dig a hole to the dimensions of the pool, measuring frequently. Ensure you set a grade so that it slopes away from the pool. This is essential before you begin pouring concrete for a deck around the edges.
