Choosing a pool type is the single most important decision you will make — it affects your budget, timeline, maintenance routine, and how the pool looks in your backyard a decade from now.
Fiberglass pools arrive as a single pre-molded shell that a crane lowers into the excavated hole. The gelcoat surface is smooth and non-porous, which means algae has a harder time taking hold and you use fewer chemicals. Installation is fast — 4 to 6 weeks from dig day to swim day. The tradeoff: you're limited to factory shapes (usually 14'–16' wide rectangles, freeforms, and Roman-end designs) and transport logistics to your site must be viable. Fiberglass now represents roughly 22% of new in-ground pool installations in the Southeast according to the Pool & Hot Tub Alliance (PHTA).
Vinyl liner pools use structural wall panels (steel, polymer, or aluminum) with a custom-fabricated vinyl sheet that forms the watertight interior. The liner feels soft underfoot — no scraped toes — and comes in dozens of patterns. Shapes are more flexible than fiberglass but less than concrete. The liner itself must be replaced every 8 to 12 years at a cost of $4,000–$6,000, which is the primary long-term expense to factor in. PHTA data shows vinyl liners account for about 18% of new Southern installations.
Concrete/gunite pools are the gold standard for permanence and customization. Every dimension, depth profile, and edge detail is built to your specification on-site with reinforced steel and pneumatically applied concrete. A well-built gunite pool will outlast the house. You can integrate spas, tanning ledges, beach entries, swim-up bars, and vanishing edges — design elements the other types cannot match. The cost and timeline are highest, and the plaster or pebble interior needs resurfacing roughly every 10–15 years at $6,000–$12,000.
For Milton's specific conditions — clay soil, freeze-thaw cycles a few nights per winter, and sloping lots — we typically recommend concrete/gunite for buyers planning to stay 10+ years and fiberglass for those who want a quicker, lower-maintenance option. Every Milton Pool Crafters project starts with a free site evaluation where we walk your property and discuss which type makes sense for your goals and landscape.
