Being a pool owner, let me first say we know that boats are holes in the water you throw money in. Pools are holes in the ground you throw money AND water in.

Moving on.

Fiberglass is limited in size. Gunite/concrete can be completely customized and whatever size you want. However, with concrete you have to keep a good eye on calcium levels or it will leech out of the concrete itself. I have a vinyl lined pool myself but only because the house had it installed already. Next time the liner tears it will get filled in. One thing you have to realize is the costs involved are not just the install. The water, chemicals, and power to run the pool add up very quickly. Mine was about $100 a month during peak season (south Alabama) and now it's a frog pond because pools are DA DEBIL.

Yeah , my last house had a concrete pool , so I get what you're saying .
We are buying a house and want a small pool put in , maybe 12 x 26 , and it seems like the initial install is cheaper and a lot faster with a fiberglass pool .
I don't know of anybody who has actually owned one , I was hoping for some real time experience with fiberglass pools , but thanks !

Have a geo analysis done of your soil. See if it’s good and stable or Poor soil.

Had a fiberglass pool in Charleston SC and now have a gunite pool in FL. Both excellent. $100 a month to maintain pool? What a crock of shit. Run a salt system, It costs me about 2 bags of salt @ $6 a bag every couple of months. 1 gal of acid @$7 will last me a month. That's it.

Had both, and recently installed a fibreglass pool, way better than concrete (in my opinion) of course you are limited in size and design, but almost any style is available, had a pool since the 70's, they are not expensive to maintain or time consuming. Once you get the hang of keeping it right it's easy, big costs come in when you take water to be tested at a pool shop, they will sell you a warehouse full of over priced chemicals, most are not needed or can be sourced elsewhere for a quarter the price.

^^ This...
We installed a fiberglass pool 5 years ago. Heated, Salt water. About the same size you’re considering (12x30). I bet I haven’t spent $1500 in 5 years maintaining it. Biggest expense was replacement of the salt ionizer cell (about $450-550).

A couple of planning issues to consider for fiberglass:
1. It’s going to be delivered in one piece. Can the pool company get something that size into your yard? We have a gate at the front of our neighborhood and it wouldn’t fit through on the flatbed. Major pita.

2. If you have a high water table, plan on additional expense to backfill with gravel to support the exterior walls of the pool.

Looking back - I wouldn’t do anything different. We love our pool and use it often.

Thanks guys ! We have a small yard , thats about the only size we can fit in there . But the width won't be an issue , should be able to back it right to the hole .

Fibreglass pools are really quite light, mine was lifted over my garage from the street behind, and straight into the hole, the crane operator couldn't see the hole, it was all done by radio.

I took care of pool as a kid
i wouldnt want to do again.

Vacuuming, skimming leaves, removing dead frogs, adjusting chemicals, scrubbing algae periodically.

Keep it. Unless its an indoor pool. Or that you have kids you can make take care of it. Or you just have a lot of time on your hands.

at the very least, don't consider it if you have trees in your yard....And you're going to pay a little more for your insurance also...

If you're the kind of person that sweeps their driveway twice a day then go for it.... It'll be right up your alley.

friend of mine bought a house once with the pool and the first thing he did was fill it in.

there's a real reason there's pool companies that specialize in taking care of them for people...... If you want to use it Saturday you got to be cleaning it all week

Then, if you got a big dog haha....more work. Then there's the constant worry about small kids or grandkids etc if you've got any of them around..... Even smaller pets can get stuck in them and drown.

Indoor enclosure..... Makes it a lot easier.

Fiberglass all the way....feels SOOO much nicer on your feet than any cement pool I have been in, no matter how fancy of a surface it was.

Concrete with Pebble Tech or similar.

We have a small pool (6,000 gal) in a pool cage and it only needs minimal effort to keep it nice, even with a yellow lab swimming in it.

One thing I’ve learned about having a smaller pool is that it’s much, much easier to maintain. Especially if it’s screened in.

X3 on fiberglass. Ours is 19 years old. Since it’s screened, we don’t get many bugs or leaves. The salt system makes care easy and inexpensive. We have a solar heating system and can use it almost year round in Northeast Florida.

Second going with fiberglass. I had a fg pool installed about 5 yrs ago. I had limited experience with concrete pools as a teenager.

Gunite pool. I can't remember the last time I saw a plastic pool here. If you pump all the water out of a plastic pool, often they will float out of the ground.

Gunite pool with pebbletec finish will cost a little more but will have a better resale value; not that pools have a great ROI.

FG pools popping is a very real thing. I have witnessed several. IMO you should never fully empty a fg pool or even empty too far below the skimmer if you choose to do so for "winterizing".

At the time I had the fg pool installed, I was not aware, or maybe it wasn't available then, of the hydrostatic valves that can be placed on the bottom of the fg pool if you are in an area with a high water table. The concept is if the pressure becomes to great below the pool, they will open and allow the ground water into the pool so the pool will stay put. Easier to clean out the pool versus resetting or replacing the pool.

I had some pipework installed to allow for a well pump to be placed below the pool to pump groundwater/remove pressure if the pool ever needs to be emptied. I don't really know how effective that would be, but that was supposedly a standard practice at installation time.

Current home has a fiberglass pool, the first I've had. Direct comparison to gunite, I'd say the fiberglass needs brushing more often but it's easier to maintain water balance.
I still use chlorine and tablets are $100, shock about another $100, and probably $300 in various other chemicals like soda ash and stuff like that.
I've always had DE filters with my gunite pools, but this one has a sand filter and it's easier to maintain than DE.

Smittys ground water level is pretty high.
