Hello all,

Sorry for the lengthy description in advance.

I am planning to install a concrete or fiberglass pool in my backyard. Let me first describe my backyard. I have three areas that potentially can be used for the pool. The first area is right in front of the living room, but I have two large trees and a concrete pad (16’x24’) that needs to be demolished for the pool. This area is 24’ x 31’ when cutting one tree and 37’x31’ when cutting two trees (including 16’x21’ of concrete pad). Note that the 31’ dimension is from the face of the house to the face of the fence, and we have a 5 ft easement that we need to consider. This is the best view from the house to the pool. The second area is on the right side of the living room. It still has some view from the living area but not the best. This area is a trapezoid starting from 20 ft and finishing with 30 ft with a distance in between as 41 ft. Again these dimensions are from the house to the fence. Still, one large oak tree shall be cut. The third area is on the left side of the house and has no view from inside of the house. The area is a trapezoid starting 20 ft and finishing with 43 ft and a distance between as 51 ft. Again, all dimensions are from the building to the fence. No need for cutting three or demolishing any other items.

First, I am not sure if demolishing concrete or cutting a tree can cause issues for fiberglass or concrete installation. I have learned that fiberglass pools are very quick to install, have good longevity and require less maintenance, and have a bit less cost of installation compared to concrete pools. The limitation would be the shape, which we are not concerned about since we are looking for a modern rectangular look. I am wondering if there would be any limitations for fiberglass pool handling in our backyard due to trees, etc., since they are prefabricated and will be installed in one piece.

I also noticed that the majority of pool companies do concrete forms and not fiberglass pools. Any reason for that or is it just not a traditional method and fewer companies are getting into it? Any recommendations for companies in the Katy, TX area or companies that would support the Katy area? I have read that the seller of the pool may not be the same as the installer. Can we pick the installer or do we just pick the seller?

As far as features of the pool, we don’t want to have the whole pool to be warmed up, and we just want to have a small tub that can be heated in the winter time. What are the heating suggested systems here? Is the furnace with natural gas a good option? We are looking for saltwater instead of chlorine due to skin sensitivity. Any particular model or system shall be considered? How about the filtration?

I have seen sometimes pools may need to be completely drained for any repair reasons or water contaminations or any other reasons. While I understand that it is not recommended to keep the pool empty for a long time for any type of pool, I have seen that there is a major concern with emptying fiberglass pools due to earth pressure, and they may pop up and structurally damage. Is that a correct statement? If it is, so if needed to empty the pool, are there any solutions?

Do we have control over the slope of the floor on fiberglass pools? Or is it per manufacturer tile on the wall of the pool with saltwater, any consideration should I have? What type of pump do I need? Variable? What is the criteria for choosing that?
What is the realistic size of the pool we can have based on the dimensions I have.

Welcome! :wave: Lots of questions I see. Ha. I'll try to get you started.

First, FG is quicker to install and a bit cheaper. There are no start up issues as with plaster, so that is easier, but from then on taking care of the pool is the same.

Placement is a personal choice really for visual issues. But consider your electrical availability, the direction of the sun in the evening, and wind direction. If you have benches or shelves, you may not want the sun in your face. The typical wind direction is important so that it blows surface debris into the skimmer.

Whomever you purchase a FG pool from should have their own install team, but they may sub out some things like concrete decking. Plaster jobs could see a few more subs all around.

You will want a SWG to make chlorine, and a variable speed pump. If you want automation, that can drive the brand you choose.

As for a spa or hot tub, be sure you want that as part of your pool. To heat it means you are using a lot of energy. Some people elect to go with a separate hot tub for that reason.

Lots of things to consider, but we'll be glad to help.

Do you know of anyone with a fiberglass pool in the area? I suspect most will be gunite (concrete) pools.

While we can argue if it has merit or not, some buyers may be turned off by a fiberglass pool and I would be concerned about the impacts to your resale value. Do you know a realtor that you could ask for their opinion?

I’m aware of dozens of pools in the area online and in person. None of them are FG. On my block 6 of 6 pools are concrete/gunite.

Houston has very expansive soils. I suspect this is a reason FG is not popular. No idea if that concern is warranted, as I never considered FG.

Concrete pools need to be replastered, but a properly designed/constructed concrete shell should last a lifetime. I understand that FG has a usable lifespan. There is essentially no difference in maintenance, after the initial plaster start-up.

That being said, I’ve seen the FG pool supplier off of I-10 for many years, so people must be buying them.

Hopefully someone will respond who has built FG locally.

PM me if you are interested in a referral for a concrete pool contractor that I recommend 100%
 
Great responses already. Thanks for taking time.
I guess the main concern is if fiberglass pool is the right choice for houston and if there are any reliable installers to provide service for Katy, TX area

I would appreciate providing a contact person for concrete pool, incase the path changed to concrete pool
 
I had a Fiberglass pool in Florida and we loved it. When we started looking here in Texas the Fiberglass contractors were dump the the pool in and leave. They were not about anything extra. I did not get the best feeling from them either.
 
We are looking for saltwater instead of chlorine due to skin sensitivity.
I wanted to touch on this. As much as I love my SWG, and had #2 in hand before I even signed the build contract, if you have no issues taking a shower/bath, you'll have no issues in a TFP liquid chlorine pool.

Every pool you've ever been in likely was not sanitary. They all needed more chlorine, not less. The gross smell and feel is from the chlorine neutralizing organics and nasties, and if it it was properly sanitized in the first place, there'd be no chemical reaction going on.

I fought HARD against a pool for years because all my friends pools were gross and I ran home to shower after. They also spent hundreds, several times a season with green water. You will have none of that. Zero. Zip. Nada.

We'll get to the long chemistry details later, but the Cyanuric Acid / stabilizer in the water buffers the chlorine so properly balanced pool water is less harsh than tap water. You'll love it either way.

The SWG adds the same chlorine to the pool, just a different way and automatically so you don't have to. They are the bees knees but fair is fair and using liquid chlorine instead is a non issue. I always thought my first pool was special being salt. Friends with skin conditions loved it too and some would only swim at my house. For pool #2 I had to be a liquid chlorine pool for a bit at first and it was no different than my old pool feel wise. The TFP protocols made amazing water both ways. I noticed no improvement when I converted pool # 2 to salt.

Also, you'll need liquid chlorine at times even with a SWG. Look up Patriot cleaning supplies in Katy. They sell the good stuff for CHEAP ($3.25 for a gallon of 12.5%). Home Depot for example gets $9+ for 10%

A few members confirmed last year they were legit.

Thanks for your responses.... I am a bit concerned about the installation and issues that can happen for fiberglass. I am wondering if you know good installers in Katy or Houston area.

I'm afraid I don't have any experience with installers over there. You might reach out to Gary's Pools & Patio here in San Antonio. Maybe they can refer you to someone they are familiar with in the Houston area.

Have you made contact with any installers of FG pools in Houston? I see signs for FG pools near the Bucees on I-10 going west from Katy.
Everyone I know has installed concrete pools in the area but that is not to say that FG would not be good. One issue is to ensure there is sufficient room for a crane to lift a FG pool into place.
 
Hello Everyone,
I am learning about how I can add a pool to my backyard the cheapest way and have a good quality pool. I am still thinking both concrete and FG pools.
I ran into info about "DIY Pools" and seems they are charging about $3200+/- fee for consulting and desiging the pool you need and helping you with finding contractors and support you during bid, during construction, etc. They claim that they can reduce cost of the pool by 25-30% going through them. Because we will be basically general contractor, which makes sense. I am wondering if anyone had experience with that and for me that doesnt have experince in pool, does it makes sense to do it?
They seem to be more toward concrete pools. I guess they have more experience with that and the contractors they know probably are more concrete contractors.
Any thoughts?
I would appreciate any comments. I live in Katy, Tx.
 
T,

If you are not getting a saltwater pool, you need to find another pool builder... :mrgreen:

Have you ever been in a gunite spa before?? Is so, and you liked it, great!! If not, you really, really need to try one before you buy one.

I'm am a Pentair fan...

Thanks,

Jim R.
@Jim

I am new to pools and doing research to have a pool in my backyard. Having the first company for free consultant, they mentioned that salt water will cause corosion on the windows and other things on the house that is exposed to the pool (pool is within 5-7 ft from the the house wall). Also, mentioned that the coping and tiles cannot be certain material because of salt. Are these correct?
 
Nima,

Saltwater pools are not like the ocean, which has 35,000 ppm of salt. The water in a saltwater pool only has about 3,500 ppm of salt. About the same as your tears..

Your pool builder is just full of bull feathers. Here is my personal experience...

I have three saltwater pools, that all have been saltwater for over 10 years.. I have had ZERO corrosion issue, with the equipment, or any of the surrounding buildings, decking or material. That would be NONE...

One of the pools needed to be replastered, new waterline tile installed and new coping. We went with Flagstone.. The installer said we could not have a saltwater pool because it would 'eat' the flagstone. For the first two years after the upgrade, the pool was maintained using chlorine tablets. Within a few weeks of the Flagstone being installed, about half of the stones started shedding very thin layers of sand. Some stones shed and some did not. Good and bad stones were right next to each other. After two years of this, I got tired of tablets and we converted to saltwater.. That was over 10 years ago and the shedding is the same today, as it was before we converted to saltwater. The point being that the saltwater did not make it any better, or any worse. The problem is the cheap stone... not the saltwater. Keep in mind that this has been going on now for about 12 or 13 years and the Flagstone coping, although still shedding, does not appear to be any thinner than when it was installed. I am sure it is somewhat thinner, but not enough that anyone would notice.

I will never own a pool again that is not a saltwater pool. I'd just as soon fill them full of dirt... :mrgreen:

Thanks,

Jim R.

Salt doesn't evaporate and your builder is ignorant.

Will all said things occasionally get hit with a drop from a cannonball ? Sure. But it's no worse than a liquid chlorine pool.

Poor quality materials weather in the elements. The pool is irrelevant besides that its wet. Ask alot of questions at patio time because TX has some weak stones locally and they get misused on pools.

To add...."chlorine" pool owners would be shocked to find out their pool has as much salt as "salt water" pools. All the junk you'll end up putting in your pool if you use those tabs will add a little bit of salt. After a year or two, that little bit each time adds up to a whole lot. Pool owners who have salt chlorine generators have a stable level of salt as they don't manually add anything that adds salt.

Thanks Jim,
So, would you recommend the salt water system instead of chlorine then? What slat water system(specification) would you recommend for below pool size. I'll have a 31 square foot spa as well

I am looking to install a 93 ft pool perimeter(14'x33' and 3 to 5.5 deep)
