*** WE DO NOT BUILD, SELL OR SERVICE ABOVE GROUND POOLS. In-Ground Pools Only *** Prestige Pools & Spas is St. Louis’ number one award-winning pool and hot tub company. We have served St. Louis and its surrounding communities proudly for over 40 years. We specialize in vinyl liner pools by Latham, fiberglass pools by Trilogy, and gunite in ground pool construction. We also offer a variety of premier hot tub and swim spas.We have an A+ BBB rating. We are a year round full service and In-ground pool and spa installation company. We have a full time staff for both service and showroom. WE DO NOT BUILD, SELL OR SERVICE ABOVE GROUND POOLS.

"Horrible! Prestige pools promised the world when selling us the pool and fell short at every turn. I own a home renovation company so know the game. Signed contract because they promised it would be built before the winter. Mid June after many calls they finally started. They worked a day here....a day there....never letting us know when or why . I made many calls asking when the guys would build because of what was promised and I needed to get more concrete done around the pool once they were done. Secretary every time was like talking to a recording, saying the same bull they tell everyone on why pool wasn’t done. I ended up hiring my own crew to backfill ditch in yard and grade yard that had huge piles of dirt for months left . They left a massive pile of gravel in middle of yard no where close to pool for me to get rid of. My pump pipes leaning so bad I have to re do. Concrete around the pool is undermined all over . Left concrete dust in pool and made us vacuum up. Cracks in concrete, tape , caution tape, and trash left all over the place. No matter how many calls I make they never show to finish. They take half the money on start, almost half half way through, and never show up to finish. They take as many jobs as they can to sell and once they get money you will wait forever to get started and they will put you on the back burner to finish if they even do. Worse experience ever. If I ran my business like prestige I wouldn’t have a business"

Pool Construction and Installation questions, answered by experts

Check with your local laws, which might state that you have to build a fence around your plunge pool. If you have children or pets or live in an area with abundant wildlife, you should consider building a fence around your pool for safety. Pools can present a drowning hazard, and while plunge pools are not very deep, younger children can get hurt if they try to dive into them. A fence can help protect your family and visitors from injury.

When designing your dream pool, it's important to leave enough room for safe walkways, patios, and extras such as outdoor kitchens and fire pits. Your local building codes may specify the minimum space between your pool and your house, utility lines, and property line. In most cases, the area of the patio around the pool should be equal to or greater than the surface area of the pool.

Depending on your budget, wants, and needs, a pool enclosure can be a worthwhile investment. It all comes down to how much you use your pool, and what it would mean to you to have year-round access to it.

If you know that you'll swim in your pool a lot, then having an enclosure means you don't have to worry about the weather. It's also a lot easier to maintain the water, because you don't have to deal with leaves falling into the pool, and the water's chemical levels tend to be more stable.

There are many factors to consider when building an in-ground concrete pool. This includes the pool’s primary purpose (relaxation or exercise) if you live in a warm or cold climate (how often it’ll be used), and if you have the budget for chemical treatments and pool maintenance. In-ground pools are often more costly than aboveground pools, but they’re considered more luxurious and hold more value.

The best way to heat a swimming pool depends on your pool and location. Those living in sunny environments may find that a solar-powered heater works just fine, but you may need something more reliable, like a gas or electric heater if it’s often cloudy where you live. When in doubt, try a few lower-cost options first to see if they meet your needs before going all in on a more expensive heater.
