The Real Cost of Owning a Pool in St. Louis: A Year In
Pools are for people who love work and hate money.
That about sums up the real cost of owning a pool in St. Louis, and it was great expectation-setting on the part of our pool inspector.
Undeterred, we bought the pool. It came with a house.
Halfway into the first full season, here are some things I’ve learned about pool ownership.
The Real Cost of Owning a Pool: Opening, Closing, and Maintenance
We left our pool open through the end of October last year. Mistake. It was way too cold to use it. We opened the pool in March. We were tired of looking at the cover. But March was way too soon to open a St. Louis pool. For the first month, I never got in, just skimmed and skimmed and skimmed. Filthy trees just kept dropping pollen in the pool.
This year we will close at the end of September and wait until late April to re-open it.
OPENING: $385–$500
CLOSING: $150–$300
ONGOING MAINTENANCE: If you hire it out, expect to pay between $200–$500 a month in St. Louis for regular service, with an average around $330. Weekly basic care (chemical checks, filter cleaning) runs lower, closer to $30–$95, while more comprehensive weekly or biweekly service climbs toward $150. Concrete pools cost noticeably more to maintain than fiberglass, mostly because of chemical use. The Pool & Hot Tub Alliance Maintenance Checklist can help keep you on track.
EQUIPMENT & REPAIRS: Pumps, filters, heaters, liners — they all have a lifespan, and none of them are cheap when they go. A vinyl liner replacement alone can run $3,000–$7,500. This is the line item that catches new pool owners off guard: it’s not the big splashy expense, it’s the slow drip of smaller ones.
INSURANCE & TAXES: A pool is an insurable asset, which usually means a bump in your homeowner’s premium. And because an inground pool can add roughly 5–7% to your home’s value, don’t be surprised if your property assessment — and your tax bill — reflects that too.
ENERGY: Pumps and heaters run on electricity, and if you’re not on a variable-speed pump, you’ll feel it on your utility bill from Memorial Day through Labor Day.
TOTAL: Add it up, and a realistic annual cost of pool ownership in St. Louis lands somewhere between $2,000 and $5,000+ once you factor in opening/closing, routine maintenance, chemicals, and the occasional repair. That’s real money — the kind that deserves a line in your household budget, not an afterthought.
The Pros of Owning a Pool (Because There Are Real Ones)
IT GENUINELY CHANGES YOUR SUMMER
Before having a pool, swimming as a family was an ordeal: find swimsuits and sunscreen, make a plan, coordinate schedules. After all that effort, we’d spend hours or a full day just to make the prep worthwhile. Now we go for 20 minutes here and there. We hop in to cool off after taking care of the lawn or going for a walk. Night swims under the stars — that’s an evening game changer.
IT’S A GATHERING PLACE
Neighbors, kids, friends, book club — a pool has a way of pulling people toward your house instead of away from it. In a season where a lot of us are craving more in-person connection, that’s not nothing.
Does a Pool Add Value to Your Home in St. Louis?
In luxury and move-up markets like Ladue, Kirkwood, and Webster Groves, a well-maintained pool is often expected, not optional. It can meaningfully widen your buyer pool when it’s time to sell, particularly for homes priced above $750K.
But it’s not a universal value-add. In more modest or starter-home price points, a pool can actually narrow your buyer pool rather than widen it, especially for buyers with young kids who see it as a liability rather than a feature. This is very price-point and neighborhood dependent, which is exactly the kind of thing your realtor should be able to walk you through before you list — or before you buy.
The Downsides of Pool Ownership (Said With Love)
IT’S A SECOND YARD TO MAINTAIN
Between skimming, chemical balance, and equipment checks, a pool asks for attention on a schedule — not when it’s convenient for you.
THE COSTS ARE ONGOING, NOT ONE-TIME
Whatever the sticker price was to install it, budget for it to keep asking for money, every single season, for as long as you own it. That’s the real cost of owning a pool — it doesn’t stop after installation.
Worth It?
So far, YES! With the learning curve behind us, we’ll definitely do some things differently, but overall it’s been a real joy for all of us.
