Overflow pool (also known as vanishing edge or infinity pools) have a unique design where the water flows over one or more edges of the pool, creating a visually striking effect. This type of pool is popular for aesthetic purposes, particularly in locations with scenic views.
How it works
- The pool is designed so that water flows over one or more of its edges (usually one side or the entire perimeter), creating a seamless transition between the pool water and the surrounding environment.
- The water that overflows is collected into a catchment area or trough, which is located below the level of the pool.
- The collected water is then pumped back into the pool, making it a continuous flow system.
- Overflow pool require a special system that includes a series of gutters, channels, and sometimes a secondary filtration system to handle the overflow water.
Advantages
- Offers a dramatic and beautiful visual effect, particularly with a backdrop such as the ocean, mountains, or other scenic vistas.
- Provides a more efficient means of surface water removal since water is continuously spilling over the edge, preventing debris buildup.
- Often used in luxury or high-end pools to give an “endless” or “infinity” appearance.
Disadvantages
- More expensive and complex to build due to the specialized design and additional components.
- Requires more maintenance to ensure the overflow system remains functional.
- A higher level of expertise is needed for installation.
- It can be less practical in certain climates or locations due to the amount of water required to maintain the overflow effect.
Key Differences
- Water circulation: Skimmer pools pull water in from specific points, while overflow pools have water continuously flowing over the edge.
- Maintenance: Skimmer pools require more frequent debris cleaning in the skimmer baskets, whereas overflow pools manage surface debris better, but the overflow system needs to be checked regularly.
- Aesthetics: Overflow pools are often chosen for their visual appeal, especially when creating a seamless edge with a scenic view, while skimmer pools are more standard and functional.
Both designs serve different purposes, with skimmer pools being more practical for regular residential use, while overflow pool are often chosen for their beauty and luxury appeal.
About Overflow Pool Design and Pool Type
1. Types of Pools
Pools come in several forms, and choosing the right type depends on your space, budget, and desired features:
- In-ground Pools: These are permanent installations, dug into the ground. Common types include:
- Concrete Pools: Durable, highly customizable in terms of shape and design, but more expensive.
- Vinyl Liner Pools: Affordable, easy to install, and available in various shapes but require liner replacement every 5-7 years.
- Fiberglass Pools: Pre-manufactured, quick to install, and require minimal maintenance but less flexible in terms of shape.
- Above-ground Pools: These are temporary or semi-permanent structures placed above the ground, usually easier and cheaper to install but may not offer the same luxury or aesthetic value as in-ground pools.
- Infinity Pools: These pools create a visual effect where water flows over the edge, often with scenic views, giving the illusion that the pool blends with the horizon or landscape.
- Plunge Pools: Small, shallow pools designed for relaxation or cooling off. These are ideal for small spaces or urban settings.
2. Pool Shapes
Pool shapes play a significant role in both the functionality and look of the pool. Popular shapes include:
- Rectangular Pool: Classic and functional, ideal for lap swimming.
- Freeform Pool: More natural and organic in shape, often used to mimic a lagoon or a natural body of water.
- Oval or Round Pools: Curved shapes often used for aesthetic appeal and in smaller yards.
- L-shaped Pool: Combines the best of both worlds with a rectangular area for swimming and a shallow area for lounging.
- Geometric Pools: Sharp angles and clean lines, offering a modern, architectural style.
3. Depth of Pool
The depth of the pool should be considered based on its intended use. Typical depths for pools are:
- Shallow End: Usually around 3 to 4 feet deep, ideal for wading, lounging, and shallow swimming.
- Deep End: Ranges from 6 to 9 feet, great for diving and swimming laps.
- Gradual Depth: Many modern pools are designed with a gradual slope, starting shallow and deepening progressively, offering versatility for all ages and activities.
4. Pool Materials
The materials you choose for the pool surface, coping (the edge of the pool), and decking influence both the aesthetics and longevity of the pool. Common materials include:
- Concrete: Popular for custom designs. Can be finished with plaster, pebble, or tile for a smooth or textured surface.
- Tiles: Used for lining the pool or creating custom mosaics, tiles offer durability and can enhance the aesthetic appeal of the pool.
- Pebble/Exposed Aggregate: A textured surface made from small stones that offer a more natural look and feel.
- Vinyl Liners: Used in vinyl pools, liners come in a variety of patterns and colors and are replaced periodically.
- Fiberglass: Durable, non-porous, and low maintenance; fiberglass pools come pre-fabricated in set shapes.
5. Water Features
Adding water features can elevate your pool design, making it more attractive and relaxing. Popular features include:
- Waterfalls: From simple to elaborate designs, waterfalls add both visual interest and soothing sounds.
- Fountains: Located at the pool’s edge or center, fountains can create a dramatic effect.
- Geysers or Jets: For added fun, water jets can be installed for a more dynamic experience, including spa jets or bubblers.
- Scuppers or Spillways: Water flowing out of a scupper or spillway can create a visually appealing feature, often in overflow pool designs.
6. Lighting
Proper pool lighting is essential for both safety and ambiance, especially if the pool will be used at night:
- LED Lights: These are energy-efficient and come in various colors and intensities to create different moods.
- Fiber Optic Lighting: These can be used for under-water lighting, or around the pool’s perimeter, offering a more dramatic effect.
- Underwater Lights: Typically placed along the pool’s floor or steps, illuminating the pool’s depth.
7. Decking and Surrounding Areas
The deck area is as important as the pool itself, and choosing the right materials for it enhances both functionality and aesthetics. Materials include:
- Concrete: Versatile and customizable, concrete is a popular choice for pool decks.
- Wood or Composite Decking: Wood provides a natural, warm look but requires regular maintenance. Composite materials are low-maintenance alternatives.
- Stone or Pavers: Flagstone, slate, or pavers create a luxurious and natural atmosphere but can be more expensive.
- Tile or Brick: For a sophisticated and clean design, tiles and bricks can be used for the deck.
8. Pool Equipment
The proper pool equipment is essential for ensuring your pool stays clean, safe, and functional:
- Filtration System: Helps remove debris and keeps the pool water clean.
- Pumps: Circulate water through the filtration system.
- Heating System: To keep the water at a comfortable temperature, especially in cooler climates or for extended pool use.
- Chlorination System: Either traditional chlorine or saltwater chlorination can be used to maintain water hygiene.
- Automation System: Allows you to control pool features such as heating, lighting, and water circulation remotely.
9. Safety Features
Safety is a key consideration in pool design. Common safety features include:
- Pool Covers: Automatic or manual covers to prevent accidents, particularly for families with children or pets.
- Fencing: A secure pool fence can prevent unauthorized access.
- Non-slip Surfaces: Especially around the pool deck and steps.
- Handrails and Pool Ladders: For safe entry and exit.
10. Landscaping Around the Pool
Landscaping can significantly enhance the pool’s overall look:
- Plants: Adding plants like palm trees, shrubs, or ornamental grasses around the pool creates a tropical feel.
- Grass: Surrounding the pool with grass can help keep the area cooler and provide a comfortable, soft surface.
- Privacy Screens or Fencing: Installing plants, screens, or walls can add privacy and help define the pool area.
Example Overflow Pool Designs
- Classic Rectangular Pool with tile finishes, surrounded by a stone deck and modern, minimalist landscaping.
- Infinity Pool on a cliffside, overlooking the ocean, with sleek, dark tiles and a waterfall feature.
- Natural Freeform Pool surrounded by tropical plants, rocks, and a waterfall feature, with a sandy beach entry.
A well-designed pool is a combination of functionality, safety, and beauty. Make sure to tailor the design to your specific needs and space to create a relaxing and enjoyable oasis.
