I've got the same question except my pool is 20 years old. It's 18' by 38'. Bill

I did this about 2 years ago. It was more than I wanted to do but well worth it. The vinyl liner was needing replaced and I originally wanted a fibreglass coat put in. When we emptied the pool we discovered that the floor of the pool was not built for a gunite frame. So we had to take out the sides and floor and rebuild the frame and put on the gunite. It was about $17,000 all inclusive in 2002. New steps and a light were included.

As a professional pool builder that has shot gunite pool shells inside existing vinyl liner pools, I can tell you that the job is actually harder than building a pool from scratch. If your just going to shoot inside the existing hole the pool will end up being smaller and shallower as well to accommodate for the 6 inches of gunite that will be added. All of the existing returns have to be cut out and extended to allow for this, the main drain should be dug up and replaced with a gunite drain, and the skimmer should be cut out and replaced with a gunite skimmer. the deck should be cut back, but alternately coping can be installed to line back up with the existing deck. The deck will have to be cut out around the vinyl skimmer to make way for the gunite skimmer replacement, I have seen people not replace the skimmer but this leaves a good place for a future leak, I wouldn't recommend it. The plastic steps will have to be removed as well. You may want the bottom dug out so it can be made deeper and larger as the hopper area on most vinyl pools are small and tapered. It's a job to say the least, but it is possible. Cost wise it will probably run more than building a gunite pool from scratch. The only things you are using over is the deck, the hole, and the plumbing.For more information howtobuildaningroundpool.com

If you are talkin about a vinyl lined pool the answer is yes you can.

An inground pool is typically lined with either gunite (concrete), fiberglass, or vinyl. Gunite and fiberglass are roughly the same cost, whereas vinyl is considerably cheaper. With the lower price comes less durability, as vinyl lining has to be replaced every 8-10 years or so, whereas the other two can last for decades. Vinyl is also much easier to puncture or otherwise damage. That said, many people still prefer vinyl inground pools due to the lower cost.

u can NOT convert one into another.... ud have to rip it out and start over... either gunite or fiberglass

Gunite is covered with plaster. It is sprayed on concrete sorta. They mix it in the hoses and it is blown on. You can go to youtube and see them gunite a pool. I am only aware of plaster, vinyl or painted pool surfaces. The vinyl is just like thin rubber.

Yes, this can be done however, basically the only thing you can use from your vinyl pool is the actual 'hole' and maybe equipment. The cost is not much less than having a new gunite pool built.

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.

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!

Swimming pool types include above-ground pools, fiberglass pools, vinyl-lined, gunite and poured-concrete pools. Learn the pros and cons of each type of pool.

Gunite is a type of cement mix used in the walls of the pool, whereas a vinyl lining is just a layer on the walls, generally used for waterproofing purposes. So, either of them will do, but my personal opinion is that using a lining is always better (hence vinyl lined pools are very common in England and other countries)

I have not heard of it being done before I have heard of fiberglass conversions however

The in-ground pools are prefabricated. The bodies are made of fiberglass-reinforced plastic. This is an alternative to vinyl-lined, gunite and poured concrete pools.

All day long. Concrete pools have real tile instead of the fake liner tile look. You can update a concrete pool later on as styles change: with vinyl it's final.

Inground vinyl is better, their is less exposed part to the oxigene, therefore, last longer.

Depends on the type of pool, i.e. inground or above ground pool. * My brother has had an inground vinyl lined pool for at least twenty years. He ives in an area which is southwest of New Orleans. That pool has survived more pool parties, hurricane parties, followed by hurricanes themselves (including Katrina) without a tear nor a leak. My above ground pool is a Doughboy and it has the side walls concreted into the ground. It is now eight years old. It survived hurricanes Lily, Katrina, and Rita in just the past 4 years. However, if you can afford it, gunite is probably the best. Around this area, fiberglass is often too light in weight and will float up with floods.

I say gunite for the ability to create any shape pool you desire. Otherwise, you are stuck with the pre-fab design of the vinyl variety.

Expensive. The dig is probably one of the least expensive parts of the inground pool process. Essentially when you pull the vynal out that is what you have. a hole. You can plan to have the gunite shot in, replumbing, coping and decking. Then the diamon brite plaster is shot at the end. In most markets you can count on approximate costs of over $20,000.

The average cost of installing a medium-sized concrete/gunite in-ground pool is roughly $30,000 (in 2004) with no frills (such as waterfalls, flagstone, inlaid tiles, etc.). That depends on whether you are willing to take the task on yourself or whether you'd prefer to hire someone. We saved thousands on ours by doing it ourselves - thanks, The Windsor-Browns You can also save alot on the cost by going with a vinyl lined inground pool.

We used Garrett Vinyl Pools they have been around for years.

In the frost belt Vinyl is better..Gunite is one of the strongest pools but when it freezes it can crack.. I agree. Vinyl is better and it will feel so soft and smooth on your feet.

what you can do in this situation depends on what is under the vinyl liner now.

Vinyl lined pools require less chemical treatment to use since it is not a porous material unlike cement lined ones require more chemical treatment (more porous material). Cement lined ones form more algae than vinyl.

The gunite pool is basically what most people refer to as the in-ground concrete pool. Because this pool will shape to the contours of your yard, it is a great choice for those who want something more unique than the typical vinyl lined pools. The tile on the gunite pool can be cleaned with household tile cleaner when you are doing your deep cleaning of your pool. This requires that the pool be drained and rinsed thoroughly.
