Large & swim-lane pools
31 to 40 feet. A full swim lane, a real deep end, and room for a crowd. These need open excavation access and a wider deck budget.

Not sure which model fits?
The shell is only half the decision. Excavation access, setbacks, slope and where your equipment pad can go often rule models out before you ever pick a colour. We measure all of it on site, free, before you commit to anything.
Every shell listed here is manufactured by Barrier Reef Pools and installed by us in Southern Utah and Utah County. Specifications above are the manufacturer's published figures.
