The pool deck is the most important hardscape surface on any property with a pool. It is where everyone walks barefoot, where water splashes constantly, where patio furniture sits year-round, and where kids run regardless of how many times you tell them not to. In St. Louis, the deck also has to survive freeze-thaw cycles from December through March, intense summer heat that makes some surfaces too hot to walk on, and the occasional hailstorm that damages inferior materials.
Choosing the right paver for your pool deck is not just about looks. It is about safety, durability, maintenance, and long-term cost. Here is what we recommend after building pool decks across St. Louis, Jefferson County, and St. Charles County for over 20 years.
Why Pavers Beat Poured Concrete for Pool Decks
Poured concrete is cheaper upfront, but it cracks. In St. Louis, the ground freezes and thaws 40 to 60 times per season, and every cycle pushes hairline cracks wider. Within three to five years, a poured concrete pool deck in the St. Louis area shows visible cracks, heaving at joints, and surface spalling where water has penetrated and frozen inside the slab.
Paver decks handle freeze-thaw differently. Because each paver is an individual unit with flexible sand joints between them, the surface can shift microscopically with ground movement and resettle without cracking. A properly installed paver pool deck in St. Louis will outlast poured concrete by 15 to 20 years with minimal maintenance.
The other advantage is repair. If a single paver cracks or stains, you pull it out and replace it in 10 minutes. When poured concrete cracks, you either live with the crack, pay for an expensive overlay, or demolish and repour the entire section.
Best Pool Deck Paver Materials for Missouri
Concrete Pavers (Interlocking)
Concrete interlocking pavers are the most popular choice for pool decks in the St. Louis market. They come in dozens of colors, shapes, and textures, and modern manufacturing produces pavers that convincingly mimic natural stone, brick, and even wood plank patterns. As an authorized Unilock contractor, we install commercial-grade concrete pavers that carry a lifetime structural warranty.
For pool decks specifically, choose pavers with a textured or tumbled finish rather than a smooth surface. The texture provides slip resistance when the surface is wet, which is the single most important safety factor for any pool deck. Unilock's EnduraColor Plus technology maintains the color integrity for decades without fading, even under constant UV exposure and pool chemical splash.
Cost: $18 to $30 per square foot installed.
Natural Stone (Travertine)
Travertine is the premium choice for pool decks because of one unique property: it stays cool underfoot even in direct summer sun. While concrete pavers can reach 140 to 150 degrees on a 95-degree day, travertine typically stays below 100 degrees because of its natural porosity and light color. In St. Louis, where July and August bring sustained 90-plus-degree days, that difference matters for barefoot comfort.
The trade-off is cost and maintenance. Travertine needs sealing every two to three years to prevent staining and maintain its appearance. It is also softer than concrete pavers, making it more susceptible to scratching from metal furniture legs and chipping from dropped objects.
Cost: $25 to $45 per square foot installed.
Porcelain Pavers
Porcelain pavers are a newer option that is gaining popularity for pool decks. They are extremely dense (less than 0.5 percent water absorption), which means they resist staining, algae growth, and freeze-thaw damage better than any other paver material. They also come in large format sizes (24 x 24 inches and larger) that create a sleek, contemporary look.
The challenge with porcelain is that it requires a different installation method than standard interlocking pavers. Porcelain pavers are typically set on pedestals or a mortar bed rather than a sand-set base, which increases installation complexity and cost.
Cost: $30 to $50 per square foot installed.
Pool Deck Paver Patterns That Work
Running Bond
The simplest and most classic pattern. Pavers are laid in offset rows like a brick wall. It works with any paver shape and creates clean sightlines that make small pool areas feel larger. Running bond is also the fastest pattern to install, which keeps labor costs down.
Herringbone
Pavers are laid at 45 or 90-degree angles to create a zigzag pattern. Herringbone is the strongest pattern for areas that receive heavy foot traffic because the interlocking angle distributes weight across multiple pavers simultaneously. It is the pattern we recommend most often for pool decks that will also support outdoor furniture, grills, and entertaining traffic.
Random Ashlar
A mix of two or three paver sizes laid in a seemingly random pattern that actually follows a repeating module. This pattern mimics the look of natural flagstone and works particularly well with tumbled or textured pavers. It hides imperfections and creates visual interest that a uniform pattern cannot match.
Border and Field
A contrasting paver color or size runs around the perimeter of the pool deck while a different paver fills the interior field. This pattern defines the space architecturally and can be used to create a visual safety border around the pool edge -- a practical benefit that also looks intentional and designed.
Pool Deck Design Considerations for St. Louis
Drainage slope. Every pool deck must slope away from the pool at a minimum of 1/4 inch per foot. Water that drains into the pool carries dirt, fertilizer, and debris that increases chemical demand and filter load. Proper slope directs deck runoff to landscape areas or drain channels at the perimeter.
Coping integration. The pavers at the pool edge (coping) need to be a specific shape -- bullnose or rounded edge -- to provide a comfortable grip for swimmers holding the edge and to prevent sharp edges on bare skin. Many paver manufacturers offer matching coping pieces that integrate with their standard pool deck pavers.
Color selection. Lighter colors reflect more heat and stay cooler underfoot. In St. Louis summer sun, this matters. Dark pavers look dramatic but can reach 150-plus degrees on a July afternoon. A medium-toned paver in the tan, sandstone, or light gray range provides the best balance of aesthetics and thermal comfort.
Expansion space. The pool deck needs a gap between the pavers and any fixed structure -- the pool coping, house foundation, or retaining walls. This gap allows the paver field to expand and contract with temperature changes without buckling or lifting. A 1/4-inch gap filled with flexible caulk is standard practice.
How Much Does a Pool Deck Cost in St. Louis?
| Pool Deck Size | Concrete Pavers | Travertine | Porcelain |
|---|---|---|---|
| Small (300 sq ft) | $5,400 - $9,000 | $7,500 - $13,500 | $9,000 - $15,000 |
| Medium (500 sq ft) | $9,000 - $15,000 | $12,500 - $22,500 | $15,000 - $25,000 |
| Large (800+ sq ft) | $14,400 - $24,000 | $20,000 - $36,000 | $24,000 - $40,000 |
These prices include demolition of existing surface (if applicable), base preparation, paver installation, polymeric sand joints, and coping. Add 10 to 15 percent for complex shapes, radius cuts around the pool, or integrated features like fire pits or seat walls.
Maintaining Your Pool Deck
A properly installed paver pool deck needs minimal maintenance to look great for decades. Here is the annual checklist.
Spring. Pressure wash the entire surface to remove winter grime, algae, and any salt residue. Inspect joints for polymeric sand washout and refill as needed. Check for any pavers that have shifted or settled during freeze-thaw.
Summer. Keep the deck clear of standing water (if your slope is correct, this happens automatically). Clean chemical spills or splash marks promptly to prevent staining. Apply a paver sealer every 3 to 5 years for enhanced stain protection and color retention -- our paver cleaning and sealing service handles this.
Fall. Clear leaves and organic debris before they stain the surface. Leaf tannins can permanently discolor light-colored pavers if left sitting through the wet fall season.
The Bottom Line
Your pool deck is an investment that should last 25 to 30 years with the right material and installation. Concrete pavers offer the best balance of durability, aesthetics, and value for St. Louis's climate. Travertine is the premium choice for barefoot comfort. Porcelain is the low-maintenance option for homeowners who want the least upkeep.
