Different between Skimmer and Overflow type pool:

Skimmer Type Pool and Overflow Type Pool are two common designs for swimming pools, each with its own mechanism for water filtration and circulation. Here’s a breakdown of each:

Feature	Skimmer Pool	Overflow Pool
Water Level	Lower than the edge of the pool.	Same level as the edge, with overflow.
Design Appearance	Traditional pool look.	Sleek, modern, and luxurious appearance.
Filtration Efficiency	Relies on skimmers for surface debris.	Continuous overflow ensures better debris removal.
Cost	More affordable.	Higher construction and maintenance costs.
Installation Complexity	Easier and quicker to install.	Requires precise leveling and engineering.
Usage	Common in residential pools.	Preferred for luxury or commercial setups.

1. Skimmer Type Pool

A skimmer pool is the more traditional and common pool design. In this setup, the pool has a skimmer (or multiple skimmers) installed along the pool’s edge, usually near the waterline. The skimmer works to remove debris from the surface of the water by drawing water into the filtration system.

How it works:

• The skimmer is a box-like device placed at or slightly below the waterline, typically on the sides of the pool.
• Water is drawn into the skimmer through a grate, where debris such as leaves, insects, and dirt are collected in a basket.
• The water then flows through plumbing into the pool’s filtration system (e.g., pump, filter), which cleans and returns the water to the pool.
• The skimmer helps to maintain the cleanliness of the water surface by constantly removing debris as it floats on the surface.

Advantages:

• Easier and less expensive to build compared to overflow pools.
• More common, with a well-understood system for maintenance.
• Easier to install and requires less specialized equipment.
• Usually, there’s no need for an external overflow channel or tank.

Disadvantages:

• Debris can gather in visible spots near the skimmer, requiring more frequent cleaning.
• It can be less efficient at removing debris compared to an overflow system.
• Water level can fluctuate with evaporation or splash-out, so maintenance is needed to ensure the skimmer is functioning properly.

2. Overflow Type Pool (or Infinity Pool)

Overflow pools (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 pools 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 pools are often chosen for their beauty and luxury appeal.
