What is the difference between a gunite and liner pool?

Dear Theresa, there are a lot of advantages for those who appreciate innovation and comfort. This kind of pools are a new technology mostly in steel and concrete structure with vinyl liner in different qualities. The liner has better behaviour with high temperature changes,the pool structure is auto-portable this means that a soil movement won't afect it, it's faster set up, the liner is easier to clean, the liner is easier and cheaper to repair and also replaceable (new pool! new design!), liner is more comfortable for the step, and you won't think in fixing ceramic tiles or painting the pool every year,... The selection of your pool should also take in consideration the right equipment for the volume of your pool (heart of the pool). Good luck! Xavier

Gunites are nice because of the "free-form" designs that can be generated. They are solid vessel structures made of a reinforced steel cage sprayed with high pressure gunite, then coated with plaster, or tile, or combination of both. They're great in hot wether areas such as Arizona, Texas and California.

However, as mentioned in the previous answer, todays vinyl liner pools are more agile when exposed to extreme weather fluctuations. Vinyl liner pools have developed a bad rap over the years due to poor materials, or craftmanship, of many kits in the early years (70's and early 80's). But, technology has made its mark on today's vinyl pool kits. You can get walls made of high-grade galvanized steel or thick, honey-combed polymer walls that are strong enough to handle the pressure of a Hummer rolling over them. Todays floors are usually made of vermiculite (an oatmeal-like aggregate) mixed with portland cement. Suggestion: opt for dual-track aluminum coping. The lower track for the liner to snap into, and the upper track made for optional fiber-optic lighting. Even if you don't want the lighting right away, you'll have the receiver for it pre-installed incase you want it in the future.

The above answer has some incorrect information in it. The Polymer, honey-combed, pool walls are NOT strong enough to withstand a Hummer driving over it. Polymer (structural foam) panels are about as strong as anything else made out of plastic.. that's what they are... plastic. If the above information is true, I'd love to see a video of it.
