Barrier Reef Pools · Large model
Castaway Fiberglass Pool
The only Barrier Reef shell with a spa moulded into the pool itself, so one pump-and-filter set serves both.

Installing the Castaway in Utah
A 30'–35' long · 15'8" wide shell needs open access for an excavator and a crane or boom truck on set day. On tight St. George infill lots and sloped Utah County foothill lots that access route — not the shell itself — is usually what decides the model. We check it before quoting.
Once permits are issued, most Barrier Reef installs go from dig to swimming in two to four weeks. Utah County builds also get freeze-thaw-appropriate plumbing runs so the pool can be winterized properly each fall; Southern Utah builds are set up for a far longer season and higher evaporation.
