Common Questions About Choosing a Fiberglass Pool Shape
Honest answers to the questions homeowners actually ask before committing to a model.
Which River Pools fiberglass pool is best for a small backyard?
The N Series (N16) is the smallest model at 8 feet 4 inches by 16 feet, designed as a plunge pool for tight backyards. The R20 (10×20) is the next step up. The R Series and D Series both offer 12×24 sizes that fit comfortably in yards under 40 feet of usable length. Allow 8 to 10 feet of patio around the pool when calculating yard fit.
Which River Pools fiberglass pool has a deep end for diving?
The T40 is the only fiberglass model in the River Pools catalog with depth designed for diving. It is a 16×40 rectangular model with a true deep end. Most fiberglass pools, including the popular R Series, M Series, and D Series, are built with sport-bottom or flat-bottom designs that prioritize swimming and play over diving depth.
Which River Pools fiberglass pools come with an integrated spa?
Two series offer integrated spa options. The X Series (X32 and X36) includes the spa as a standard built-in feature alongside a tanning ledge. The I Series offers two specific sizes with integrated spas: the I25S (12×25 with spa) and the I30S (14×30 with spa). All other models can have a separate spa added as an add-on rather than integrated into the pool shell.
Which River Pools fiberglass pools are auto-cover compatible?
Five series are designed with auto-cover-friendly construction that hides the cover tracks under the coping: the A Series (A36), D Series (D24-D40), M Series (M25, M30, M35), R Series (R20-R40), and X Series (X32, X36). Auto covers can sometimes be retrofitted to other models with custom work, but the listed series are built for it from the factory.
Which River Pools fiberglass pool is best for a family with kids?
The A Series (A36) is built specifically for family play, with a flat-bottom design that gives consistent depth for games, volleyball, and kids splashing. The D Series and R Series are also strong family choices: rectangular shapes with bench seating, multiple size options to fit different yards, and auto-cover compatibility for safety. Families who also want a tanning ledge for adults often pick the D Series or M Series.
What is the largest River Pools fiberglass pool available?
The largest available size is 16×40, offered in four series: the C40 (freeform), D40 (rectangular with tanning ledge), R40 (rectangular with swim lane), and T40 (rectangular with diving depth). 16×40 is the practical maximum for fiberglass pool shells because the shell has to be transported in one piece by truck.
Do I need a swim lane for lap swimming?
For serious lap swimming, look for the M Series, R Series, or T40, all of which have an open swim lane built into the design. Most fiberglass pools max out around 40 feet, which is shorter than a regulation lap pool but long enough for fitness swimming. If you want a true lap pool longer than 40 feet, fiberglass is not the right pool type and you should look at concrete instead.
