When building your very own dream swimming pool, the finish is something that you need to consider. This is a huge part of the construction process and it is up to the contractor to help guide you on this. Aside from building a gunite swimming pool, another option is a vinyl pool. These are most popular up north. Craig Cohen, owner of Treasure Pools, would not recommend them at all, however; you should be informed on all of the options you have when constructing your own swimming pool.
First, off most Florida homeowners go with gunite as their finish due to the weather and ground conditions. Vinyl liners are made of polyvinyl chloride, a stretchy plastic, and are fitted over pool walls made of steel, rigid polyvinyl panels or cement. Because of its ability to flex with temperature changes, vinyl is better suited to cooler climates because it will expand and contract more easily than gunite. The typical vinyl liner is about 20 mils thick, nearly three times thicker than a heavy-duty lawn and leaf trash bag.
Aside from this type of swimming pool finish, vinyl liners typically lock their top edge, called a bead, into track located on the bottom of the coping, which is at deck level. Under the liner is a cement-like floor. Additionally, these types of pools are known to be flexible and do not generally crack like a concrete pool. Because of this flexibility, there are many design possibilities. You will also never need to repaint or re-plaster a vinyl pool. The cost will vary on multiple factors and we always encourage you to do your own research as well as speak to your own certified contractor to know what is best for you.
