Explore guniteThree ways to build an in-ground pool, compared honestly. Gunite, fiberglass, and vinyl liner each have real strengths. Here is how to find the one that fits your yard.

Start with the property and how you expect to use the water. Gunite is formed on site, fiberglass arrives as a factory-molded shell, and vinyl liner uses wall panels with a replaceable interior surface. Each construction method changes the design choices, build sequence, and long-term care plan.
Read each type in depth, then use the comparison below to see them side by side. The pool planning guide explains the site and scope factors needed for a useful proposal.
