A 24-foot round pool kit runs $2,500–$7,000 and professional installation in St. Louis adds $1,500–$3,900, so a complete installed pool with pump and filter typically lands between the two kit prices plus labor. Semi-inground pools and decks are the big step up:
| Job | Typical St. Louis price |
|---|---|
| Round pool kit (about 24 ft), walls, liner, pump & filter | $2,500–$7,000 |
| Oval pool kit (about 15×30) | $4,000–$10,000 |
| Semi-inground pool, installed | $7,500–$19,000 |
| Professional installation (kit assembly, liner, equipment) | $1,500–$3,900 |
| Site prep and leveling | $500–$1,950 |
| Electrical (GFCI circuit, bonding) | $500–$1,450 |
| Deck or platform around the pool | $3,000–$14,500 |
| Equipment upgrades (heater, salt system, robot) | $600–$3,500 |
| Liner replacement, later (every 5–9 years) | $600–$1,950 |
Missouri labor is close to the national baseline used for these estimates; pool kits are priced nationally. Wall gauge and resin-versus-steel frames, a sloped yard that needs leveling, and the deck decide most of the spread between quotes.
A pool set within an inch of level lasts; one set on a slope stretches the liner and buckles the wall. Pay for the site prep.

Above-ground pools are the practical choice across much of Missouri: the season is May through September, the pool is winterized each fall, and a resin or heavy-gauge steel wall shrugs off the freeze-thaw that cracks cheap kits.

Buy from a dealer that installs what it sells or hires a crew that does: a level base, a wrinkle-free liner and a correctly sized pump are what separate a 15-year pool from a two-season one. Check your city's permit and fence rules before the pool is ordered.
A 24-foot round kit runs $2,500–$7,000 and an oval kit $4,000–$10,000; professional installation in St. Louis, MO adds $1,500–$3,900 plus $500–$1,950 for site prep and $500–$1,450 for the electrical. A semi-inground pool installed runs $7,500–$19,000, and a deck $3,000–$14,500. Missouri labor is close to the national baseline used for these estimates.
A quality steel or resin pool lasts 10 to 20 years; the liner is the wear item at five to nine years, and the pump and filter last eight to twelve. Keeping the water balanced, the pool full and the frame away from sprinklers and chemicals stored nearby is what extends it.
Most crews level the site and assemble a round pool in one day, with the liner set and the pool filling by evening; ovals and semi-inground pools take two to three days, and a deck is a separate job afterward. Filling takes 12 to 36 hours depending on size and water pressure.
Many cities require a permit and a barrier for any pool more than 24 inches deep, and nearly all require the electrical to be permitted and bonded. Walls over 48 inches often count as part of the barrier if the ladder is removable or lockable. Missouri handles residential contractor licensing at the city and county level, so check insurance certificates and references and confirm a licensed electrician handles the equipment permit. Pool permits and residential-code barrier requirements run through the municipality.
The outdoor season in St. Louis runs May through September — about 5 months unheated. A full professional winterization each fall protects plumbing and equipment through the freeze, and spring openings cluster into the same few weeks. May through September with hot, sticky midsummers that make the pool the family HQ. Winters freeze properly statewide, so October closes and April openings frame the year.

Only pools built for it — semi-inground models have reinforced walls designed for backfill. Burying a standard above-ground pool voids its warranty and can collapse the wall when it is drained. Semi-inground pools cost more than above-ground kits but far less than a full inground pool.
A handy owner can assemble a round kit on a level site in a weekend, but leveling, liner setting and the electrical are where most DIY pools go wrong. Professional installation is a fraction of the pool's price and most dealers' warranties assume it.
