One of the most crucial yet often overlooked design elements is the pool edging, which significantly impacts the pool’s appearance, safety, and durability. So, what is pool edging called? The terminology can vary depending on the design, material, and function of the edge.
In this in-depth guide, we will explore the various types of pool edges, their functions, the terminology used in the industry, and the materials commonly employed in pool edging. Whether you’re a pool owner, contractor, or a DIY enthusiast, understanding the role of pool edging will help you make informed decisions for your next pool project.
Understanding the Terminology: What Is Pool Edging Called?
The edge of a swimming pool goes by several names, depending on its design and application. Some of the most commonly used terms include:
- Coping – The most widely recognized term in the pool industry.
- Bond Beam – The structural component over which coping is placed.
- Pool Curb or Pool Deck Edge – Often used colloquially for the border around a pool.
Of these, the term coping is the most accurate and technical name for the edging that surrounds the top rim of a swimming pool. It serves both decorative and functional purposes, forming the visible border between the pool structure and the surrounding deck.
What Is Pool Coping?
Definition and Purpose of Coping
Coping is a structural and decorative element that functions as a protective cap for the top edge of a swimming pool. It seals the junction between the pool wall and the deck, offering both aesthetic appeal and functional benefits. Coping typically extends slightly over the edge of the pool, known as a “nosing,” to help prevent water from running down the pool walls.
Material Choices for Pool Coping
Coping can be made from a wide range of materials, each offering different looks, performance, and durability. Common materials include:
| Material | Advantages | Disadvantages |
|---|---|---|
| Concrete | Durable, customizable | May crack over time, needs sealing |
| Stone (Natural) | High-end look, long-lasting | Expensive, needs regular maintenance |
| Brick | Classic appearance | Requires skilled installation |
| Tile | Matches pool interior, stylish | Slippery when wet, not very durable for edges |
The material choice for coping is not only a matter of design but also influences safety, slip resistance, and water drainage.
The Structural Side: Understanding the Bond Beam
What Is a Bond Beam?
Before coping is installed, the structure known as the bond beam must be in place. The bond beam is a reinforced concrete component at the top of the pool wall that provides critical structural support.
It serves as the foundation onto which coping is laid. The bond beam must be properly formed, reinforced with steel rebar, and poured with high-quality concrete to ensure the strength and longevity of the pool edge.
Importance of the Bond Beam in Pool Construction
The bond beam:
- Provides a stable surface for coping installation
- Helps prevent the expansion and contraction of pool walls
- Enhances overall structural integrity of the pool
In other words, while coping gives your pool its visual finish, the bond beam is the backbone that ensures durability, safety, and longevity.
Types of Pool Edging: Design and Performance
Depending on the architectural style and functional needs, pool edges come in various designs. Here’s a breakdown of the most popular types:
1. Overhang (Nosing) Coping
This is the most common type of pool coping. It features a slight overhang or nosing that directs water away from the pool deck and into the pool. The overhang also adds a smooth, aesthetic finish and reduces water staining on the surrounding surface.
2. Flush Coping
Flush coping sits level with the pool edge without any overhang. It’s often chosen for contemporary designs and integrates well with modern pool decks, especially in vanishing edge or infinity pool setups.
3. Water-In-Glass Edge
Also known as a zero-edge or infinity edge, this design allows water to spill over into a catch basin, creating the illusion that the pool extends into the horizon. The edging is typically made from granite or stainless steel for a sleek look and durability.
4. Tile Coping
Using pool coping tile, often made of ceramic or glass, offers continuity between the pool interior and the edge. Though visually appealing, tile coping may lack the durability of stone or concrete and requires careful installation to avoid cracking.
5. Natural Stone Coping
Made from limestone, travertine, sandstone, or granite, natural stone coping offers a luxurious touch. It is slip-resistant, aesthetically pleasing, and long-lasting when properly sealed and maintained.
Functions of Pool Edging: More Than Just Decoration
While pool edging enhances the visual appeal, its purposes extend far beyond looks. Here are some of the key functions:
Water Management
Coping with a nosing directs splashed water back into the pool or away from the pool structure, reducing water accumulation around the pool deck. This helps prevent erosion, staining, and slip hazards.
Safety and Accident Prevention
A properly installed coping edge offers a safe, slip-resistant surface around the pool. Rounded or beveled edges also reduce the risk of injury during poolside activities.
Structural Integrity
By covering the bond beam and protecting it from moisture and wear, the edge coping plays a critical role in maintaining the structural soundness of the pool wall.
Aesthetic Enhancement
Pool edging can complement the overall look of your backyard oasis, tying together the pool, decking, landscaping, and lighting elements for a cohesive design.
How to Choose the Right Pool Edge for Your Project
Selecting the right coping or edging design involves considering multiple factors:
Climate and Environmental Conditions
In areas with extreme temperatures or frequent freeze-thaw cycles, durable and weather-resistant materials like concrete pavers, granite, or composite stone are ideal choices.
Maintenance Requirements
Some natural stones may require periodic sealing, while tile edges may crack over time. Consider the long-term maintenance before making a selection.
Design Aesthetics
The edge should complement your overall style:
- Modern designs may prefer flush concrete or stainless steel edges.
- Traditional or rustic backyards may benefit from natural stone or brick edges.
Budget Considerations
Coping costs vary widely depending on the material:
- Tile and pre-cast concrete are generally more affordable.
- Natural stone and custom edges may carry a premium but add long-term value.
Installation Considerations: Professional vs. DIY Pool Edging
Proper installation of pool coping is essential for durability and performance. While DIY projects can work for small or cosmetic changes, professional installation is recommended for the following reasons:
Structural Expertise
Coping covers the bond beam, which is part of the pool’s structural system. Professional contractors ensure that the coping is installed correctly and securely.
Material Compatibility
Coping materials must be compatible with the surrounding deck, weather conditions, and pool structure. Professionals can advise on the best material combinations that provide both beauty and durability.
Sealing and Drainage
Professionals apply appropriate sealants and ensure water is properly redirected away from the structure, preventing long-term water damage or cracking.
Warranty and Long-term Value
Professional installations often come with labor and material warranties, which DIY efforts typically cannot offer.
Alternative Edging Styles for Unique Designs
In addition to the standard coping styles, several edging types stand out due to their unique design elements:
Vanishing Edge (Reflecting Edge)
A vanishing edge creates a visual illusion of a pool blending with the surroundings by allowing water to spill into a trough behind the edge. The edging must be made of durable, water-resistant materials like stainless steel or natural stone.
Infinity Edge
Similar to a vanishing edge, infinity pools often feature edging that seamlessly integrates with the horizon or landscape. The coping here must be meticulously crafted to maintain structural integrity while offering an unobstructed view.
Beaded or Cove Edge
This decorative style features a curved or beaded edge that offers a smooth transition between the pool wall and the coping surface. It adds a touch of classical elegance and improves slip resistance.
Steel or Metal Edging
Used in some contemporary pool designs, steel edges offer a modern and sleek look. They must be professionally installed and properly maintained due to the potential for rusting.
Common Mistakes in Pool Edging and How to Avoid Them
Poor Material Choice
Selecting an inappropriate material for the local climate or pool use can lead to cracking, stains, and safety hazards. Always consult with a professional or do thorough research before installation.
Skimping on Sealing
Many natural stones and concrete coping options require periodic sealing to protect against moisture absorption and staining. Failure to seal can lead to mold, slip issues, and deterioration.
Incorrect Slope or Water Drainage
Improperly sloped coping can allow water to pool on the deck or run down the pool walls. The ideal slope should direct water away from the structure and into the catch basin or gutter system.
Ignoring Safety Features
Slippery or sharp edges can pose injury risks. Always opt for coping with slip-resistant surfaces and ensure edges are rounded or beveled for safety.

What is pool edging called?
Pool edging refers to the materials and design elements used along the perimeter of a swimming pool to finish the edge and provide a transition between the pool structure and the surrounding deck or landscape. It is commonly known by several names, including pool coping, pool capping, or pool tile edging, depending on the specific material and installation method. Coping is the most widely used term and typically involves a cap or trim installed along the edge of the pool’s shell.
Coping serves both aesthetic and functional purposes. It provides a clean, finished look to the pool while also protecting the pool structure from water infiltration and erosion. It often extends slightly beyond the edge of the pool to allow for water to spill over into a gutter system. There are several types of coping, such as concrete, natural stone, pavers, and precast options, each offering unique benefits and visual appeal.
What are the main types of pool copings available?
There are several main types of pool coping, each with distinct properties and stylistic advantages. The most common include concrete coping, which can be formed and colored to match the surrounding design; natural stone coping like travertine or limestone, which offers a luxurious appearance and cooler surface underfoot; and paver coping, which provides durability and a modular aesthetic. There’s also precast concrete coping, which offers consistency in shape and color and is easy to install.
Each type of coping serves specific design and practical purposes. For example, travertine is popular in warm climates due to its naturally cool surface and elegant appearance. Pavers are often favored around family pools for their slip-resistant finish. The selection of coping material allows homeowners to customize the look of their pool edge while balancing practical considerations such as maintenance, cost, and safety needs. Choosing the right type depends on climate, pool style, and budget.
What is the purpose of pool coping?
The primary purpose of pool coping is to provide a safe and attractive transition between the pool structure and the deck or landscape. It acts as a cap for the pool wall, preventing water from seeping into the shell and causing damage over time. Coping also helps manage water runoff and supports the integration of safety features like handrails or gutter systems. Its design often determines the visual “frame” of the pool, which heavily influences overall aesthetics.
Beyond its structural role, pool coping enhances user experience by offering a comfortable surface to walk on around the pool edge. It also provides flexibility in design—homeowners can choose from a variety of textures, shapes, and colors to complement their outdoor living space. Whether a pool has an infinity edge, a classical tiled top, or a spill-over spa, the coping provides the final touch that blends form and function seamlessly into the architecture.
How does pool coping differ from pool tiles?
Pool coping and pool tiles serve different functions but often work together to enhance both the aesthetics and durability of a swimming pool. Coping is typically the material used along the top rim of the pool wall, extending slightly over the edge to channel water away and define the pool-to-deck transition. It is usually made from more durable, weather-resistant materials such as stone or concrete.
On the other hand, pool tiles are typically installed on the interior walls of the pool, just below the waterline, and sometimes on water features or spa overflows. These are usually ceramic, glass, or porcelain tiles designed to withstand constant immersion and protect against chemical exposure. While both elements contribute to the style of the pool, they are distinct in their placement, material composition, and functional priorities, such as coping for protection and tiles for decorative and waterproofing purposes.
What are the benefits of using natural stone coping around a pool?
Natural stone coping, such as limestone, granite, or travertine, brings a refined and timeless appeal to a pool area. These materials naturally resist fading, staining, and scratching, making them durable choices for high-traffic zones around the water. Additionally, many types of natural stone maintain a cooler surface temperature under prolonged sun exposure, which adds to the comfort of swimmers and loungers when compared to concrete or darker-colored materials.
Another key benefit of natural stone is its versatility in design. It can be cut and finished in various ways—flamed, tumbled, or honed—to suit different aesthetic preferences. A tumbled finish offers a rustic look, while a honed finish provides a smooth, elegant appearance. Natural stone coping can seamlessly blend with other stone elements in the landscape, such as walkways and patios. Despite its higher initial cost, many homeowners choose natural stone for its long-term value, durability, and superior visual qualities.
Can I install pool coping myself, or should I hire a professional?
While DIY installation can be tempting for cost-saving purposes, pool coping is a task best left to professionals. The process involves precise leveling, sealing, and placement to ensure longevity and performance. Improperly installed coping can lead to water infiltration, structural damage, and slip hazards. Each material type—concrete, stone, pavers, or precast—has specific installation requirements related to cutting, sealing, and joint spacing that require expert knowledge and tools.
Moreover, professionals ensure that coping integrates correctly with the pool’s gutter or drainage system, which is crucial for proper water management. They also handle the necessary adhesives, sealants, and mortar mixes to ensure a secure bond between the coping and the pool structure. Hiring a qualified pool contractor or masonry expert helps avoid costly mistakes and ensures that the coping will withstand years of weather exposure and frequent use while maintaining its visual appeal and functionality.
How do I maintain and clean pool coping?
Maintaining and cleaning pool coping regularly is essential to preserve its appearance and functionality. The cleaning method varies depending on the material used—natural stone may require pH-neutral cleaners to avoid etching, while concrete coping might benefit from a mild acid wash every few years to remove mineral deposits. Rinsing the coping after pool use, especially in areas exposed to splashing and chemical treatments, helps prevent staining and buildup.
In addition to cleaning, ongoing maintenance includes checking for cracks, loose pieces, or erosion in the sealing joints every few months. If water starts to penetrate between the coping and the pool shell, it can lead to costly repairs due to shifting or damage to the structure. Sealing porous materials like travertine can provide an extra layer of protection. Regular inspections and gentle cleaning routines can go a long way in maintaining a pool edge’s aesthetic appeal and structural integrity.
