Installers use vinyl liners to create inground pools without pouring concrete. Here's an overview of the topic http://www.poolandspa.com/page232.htm.
Yes it can be done
Steel walls are currently the lowest quality wall for a swimming pool, with the exception of Cyprus wood (if still available). Concrete (not gunite) is superior to any other wall, but a pool with concrete walls generally also has a concrete bottom. In other words, it is a concrete swimming pool. The most popular wall today for vinyl liner pools is fiberglass and, with the possible exception of concrete, is the best possible choice.
The reality is that the average inground pool liner will last 8-12 years.
Fiberglass pool shells are shipped in a single piece directly from the manufacturer. As a result, you don't actually linea pool with fiberglass the way you would with concrete or vinyl. Instead, installing a fiberglass pool simply means digging a hole in which to place the already completed shell.
As long as the vinyl liner pool is inground, it can be converted. But you'll probably have to remove all of the vinyl pool elements until you have reduced the pool to a big hole in the ground and then start from there. All it takes is time and money!
Yes you can but you would be replacing the liner every 3-4 years when you can build a gunite pool using the old pool as a base and get another 30-40 years of enjoyment out of it.
Ya can do anything ya desire if ya got the money
You can use the same hole in the ground for both a vinyl liner pool and a gunite pool. You should not need a new hole dug.
by taking the liner away!
is it a liner or concrete?...if it's a liners DON'T drain it any more then about 6 in. in the shallow end the liner will shrink...if concrete.....it should be fine as long as you don't have a high water table close to the pool.good luck
No. Replace the liner.
