Medium Fiberglass Pools: The Sweet Spot for Most Backyards

Medium fiberglass pools hit the sweet spot for most Kansas City Metro homes: long enough for real swimming and pool games, deep enough for a diving-type deep end, yet still manageable for typical suburban lots in Blue Springs, Independence, Lee’s Summit, and Grain Valley.

The Sun Pools medium shells we install range from 13 to 14 feet wide and 28 to 35 feet long, with depths up to 7 feet. Every model is a one-piece fiberglass pool installed by Hydro Pool & Spa — quick to build, gentle on maintenance, and backed by the durability fiberglass is known for.

Why Homeowners Pick a Medium Shell

  • Room to actually swim — 28’+ lengths give you a genuine swim lane without dominating the yard.
  • Deeper water — depths to 7’ open up more games, dunking, and diving-ring fun.
  • Built-in seating — benches, tanning ledges, and swim-outs are molded right into the shell.
  • Cover-friendly — rectangular models like St. John and Tahiti work well with automatic pool covers.
