Six Great Small Fiberglass Pool Designs

Not all yards have the space for a massive swimming pool. Bummer, I know. But did you know there are tons of great options for smaller pools as well?

If you’re looking for a pool that delivers beauty, durability, and low maintenance in a compact size, small fiberglass pools are an excellent choice. These pools offer all the advantages of larger fiberglass pools, but with dimensions perfect for smaller backyards, tighter spaces, or homeowners who want less upkeep. A well-crafted fiberglass pool shell can last for decades, providing a smooth, nonporous surface that resists algae growth and requires fewer chemicals to maintain.

At Royal Pools G2 Landscaping, we install inground fiberglass pools all summer long in Northwest Indiana. From 40-foot-long pools to small pools like the ones below, we have seen fiberglass pools transform hundreds of backyards over our 25 years. In no particular order, below are six outstanding small fiberglass options from top manufacturers, offering a blend of classic and contemporary designs.
