Gunite (shotcrete) pools offer unlimited shape customization, 50+ year lifespan, and deep spa integration but take 8-14 weeks to build and require plaster resurfacing every 10-15 years. Fiberglass pools install in 2-3 weeks, feature a smooth algae-resistant surface, and need minimal maintenance — but come in pre-set shapes with a 16-foot width limit. Most Northeast Georgia homeowners with unique yard layouts choose gunite; those prioritizing speed and low maintenance prefer fiberglass.
