Fiberglass Pools
Fiberglass inground pool installation for Davis and Weber County homeowners. Faster to install than gunite, lower maintenance surface, and a wide range of shapes and sizes — installed by one crew from excavation to water-in.
How fiberglass pool installation works and why it's faster
Fiberglass pools are manufactured at a factory — a single-piece shell molded from fiberglass and gel coat. The shell is shipped on a flatbed truck and craned over the house or fence into the excavated hole. Because the shell arrives complete, there's no in-ground construction phase (no rebar, no shotcrete, no plaster cure time). Once the shell is placed, leveled, and plumbed, the backfill and deck work can begin almost immediately. This makes fiberglass the fastest path from permit to water-in — typically 6 to 10 weeks versus 12 to 16 weeks for gunite or shotcrete.
In Utah's clay-heavy soils, fiberglass installation requires specific backfill procedures. The space around the shell must be filled with pea gravel (not native soil) to prevent the shell from being pushed up or distorted by soil movement and hydrostatic pressure. This is a non-negotiable part of a correct fiberglass pool installation — skipping it leads to shell movement. We use the correct backfill on every job.
Fiberglass surface advantages and shape limitations
The gel coat surface of a fiberglass pool is smooth, non-porous, and naturally algae-resistant compared to plaster. Plaster pools require brushing and more aggressive chemical maintenance to prevent algae; fiberglass pools are easier to keep clean. The smooth surface is also gentler on skin compared to plaster that's aged and roughened. Fiberglass surfaces don't need to be replastered every 10 to 15 years as plaster does — with proper water chemistry, a fiberglass surface lasts the life of the pool.
The limitation is shape selection. Fiberglass pools come in the shapes the manufacturer offers — typically a range of rectangles, ovals, kidneys, and freeform shapes in various sizes. If you want a specific custom freeform design, a vanishing edge, or features not available in a shell model, gunite or shotcrete is the right choice. We discuss both options honestly so you choose the one that fits your priorities, not the one with a higher margin for us.

Fiberglass Pool Questions
Common questions about fiberglass pools, installation, and Utah soil conditions.
Yes, with the right installation. Fiberglass pools perform well in Utah's climate — the smooth gel coat surface holds up through freeze-thaw cycles better than plaster (which can crack and spall). The key is proper backfill: fiberglass shells in Utah's clay-heavy soils must be backfilled with pea gravel, not native soil, to handle soil movement and hydrostatic pressure. Done correctly, fiberglass is an excellent pool choice here.
From permit approval to water-in, a fiberglass pool installation typically takes 6 to 10 weeks. The shell itself goes in within 1 to 2 days of delivery. The remaining time is backfill, plumbing and electrical, decking, and equipment installation. This is significantly faster than gunite or shotcrete custom pools (10 to 16 weeks).
No. Fiberglass pools don't have plaster — the gel coat surface doesn't need to be resurfaced on a regular schedule the way plaster does. Plaster pools typically need replastering every 10 to 15 years. Fiberglass gel coat lasts the life of the pool with proper water chemistry. This is one of the significant long-term cost advantages of fiberglass over plaster.
Fiberglass shells are flexible, which is actually an advantage — they flex under soil movement rather than cracking like concrete. Spider-crack gel coat issues can occur but are typically cosmetic and repairable. Structural cracking of fiberglass shells is uncommon with proper installation. The shell manufacturer provides a warranty, and proper installation is essential to ensure the warranty remains valid.
Fiberglass shells come in the shapes the manufacturer produces — typically a range of rectangles, L-shapes, kidneys, ovals, and freeform shapes in various sizes. The selection is wide enough that most homeowners find a shape they like. If you need a specific custom freeform design, a vanishing edge, or features not available in any standard shell, then gunite or shotcrete is the right path. We carry shell options from reputable manufacturers and can show you available shapes for your target size.
