The deck around a swimming pool isn't a regular deck. It looks like one, but it lives a different life. It gets splashed constantly. It cycles wet-dry-wet-dry on summer afternoons. It absorbs chlorine and pool-chemistry residue every time someone climbs out. It sits in direct reflected sun (water reflects more UV up than most homeowners realize). And it has to grip wet bare feet, every step, every time, because slipping at the edge of a pool is how people get hurt.
A lot of contractors will quote you a pool deck using the same playbook they'd use for a back yard deck. Same materials, same fastener spacing, same drainage thinking. That works for the section of the deck 12 feet out from the water. It doesn't work for the four-foot band right at the coping, and getting that band wrong is what makes a pool deck a problem rather than an asset.
This page is for homeowners with a pool already, or with a pool going in, who want a deck that handles all of that without becoming a maintenance burden. We work on pool decks in Pepperwood, Hidden Valley, the Cottonwood Estates corridor in Holladay, and in newer subdivisions across the south end of the valley where pools have become standard at the higher price tiers.
What chlorine, sun, and water do to deck materials
Three forces act on a pool deck constantly. Knowing how each material responds tells you most of what you need to pick the right one.
Chlorine. Bleaches wood. Discolors aluminum railing systems over time if the finish isn't pool-rated. Mostly doesn't bother composite, but the joists underneath the boards still need to be selected with chemistry in mind (galvanized fasteners corrode faster around pool chemistry than they do on a dry deck).
Reflected sun. Water reflects roughly 10% of incoming UV back upward, on top of the direct UV hitting the boards. That means pool deck boards get roughly the same UV exposure top and bottom in the sections close to the water. Composite handles this without changing color. Wood fades faster on pool decks than on regular decks for this exact reason.
Constant wet-dry cycling. Wood absorbs water during pool use, dries out between sessions, swells, shrinks, and develops the kind of micro-fissuring that turns into rot in five years instead of fifteen. Composite doesn't absorb water. Concrete and pavers don't either, but they crack in freeze-thaw if water sits in surface pores through winter, which is why pool deck drainage matters more in Utah than in milder climates.
Each of these materials have specific behaviors around chlorine that we walk through during design. There's no one-size answer, but there are clear winners and clear losers depending on the pool's chemistry and exposure.
One note on this year specifically. Utah's 2025–26 winter delivered statewide snowpack at just 60% of median, per the NRCS, and Salt Lake City logged its fewest snow-cover days in recent memory. Pool decks across the valley got more direct UV exposure than usual through what should have been protected months. Composite was the only material on this list that didn't see additional stress.
The materials that work for pool decks in Utah
Composite. The most common material we install for pool decks in 2026. It handles chlorine without issue, doesn't fade in the reflected UV, doesn't splinter on wet feet, and the textured-surface lines (most major brands offer one) provide real slip resistance. The price runs about 30 to 50 percent more than concrete and roughly the same as mid-grade pavers installed.
Pavers. Concrete pavers or natural-stone pavers (travertine in particular) are common on higher-end pool builds. They handle Utah's freeze-thaw if properly bedded with the right drainage underneath, they look right with most pool aesthetics, and they're easy to repair individually if a section shifts. The downsides are upfront cost and the joints, which can grow weeds and grow uneven over time without maintenance.
Concrete. Stamped or broom-finished concrete is the budget pool deck and what gets poured around most builder-grade pool installations. It works. It's also the surface that gets hottest in July sun, sometimes hot enough to hurt bare feet, and it cracks predictably along control joints. Re-staining or re-sealing concrete every few years is the only way to keep it looking finished.
Wood. Not recommended for the band immediately around a pool, period. We've replaced too many wood pool decks that rotted out in seven to ten years to recommend it for anyone. If you specifically want wood for the broader patio area set back 8 to 10 feet from the water, that can work. Right at the coping, choose something else.
Slip resistance is the most important spec
Slip resistance is the most important spec on a pool deck, more important than color, more important than board profile, more important than price.
And here's where the slip issue gets serious. The board that looks beautiful in the showroom may be the board that puts a child or a grandparent in the ER. Smooth composite, sealed concrete, and polished pavers can all become hazardous wet. The fix is in the surface texture, not the material itself. Capped composite with a directional grain pattern, broom-finished concrete with the right brush angle, and pavers with a tumbled or textured finish all provide grip when soaked.
We've turned down pool deck installs where the homeowner insisted on a smooth flat polished surface for the look. Not because we didn't want the work. Because the deck they wanted was going to hurt somebody, and we didn't want our name on it when it did. Choose the right slip rating for a deck that gets wet, and choose it before you choose the color.
Frequently asked questions
How much does a pool deck cost in Salt Lake City?
For an installed pool deck around an existing 16-by-32 in-ground pool (roughly 500 square feet of decking), composite runs $20,000 to $35,000, pavers run $18,000 to $30,000 depending on stone type, and stamped concrete runs $10,000 to $18,000. Pricing varies with coping detail, drainage requirements, and access. Custom shapes (curved coping, raised lounge areas, swim-up bars) add cost.
Can I use Trex or TimberTech for a pool deck?
Yes, both work well around pools and we install them regularly. Look for capped composite specifically (avoid uncapped older composite, which can absorb pool chemistry over time). The textured surface lines in both brands provide the slip resistance pool decks need. Lighter colors stay cooler underfoot in midsummer.
Does the deck need to drain away from the pool?
Yes. Salt Lake County building code requires positive drainage away from the pool coping, typically a quarter-inch per foot slope. This keeps pool water and pool-chemistry from pooling on the deck surface, prevents ice sheets in winter where any water freezes, and protects the substrate underneath the deck. We grade and detail drainage during the design phase.
What about winter? My pool closes in October.
Pool deck materials in Utah have to survive freeze-thaw whether the pool is open or closed. Concrete is most vulnerable (cracking along control joints from ice expansion). Composite is essentially unaffected. Pavers depend entirely on the bedding and drainage underneath them. Winter cover the pool itself and keep the deck clear of standing water, and any of these materials handles the season fine.
Are you licensed and insured?
Yes. We're a licensed and insured custom deck builder serving Salt Lake County. General liability and worker's comp coverage are in place on every project, and we provide certificates of insurance on request before work begins.
