Few pool features create more visual impact than a negative edge pool or perimeter overflow pool. These designs create the illusion of water extending to the horizon — perfect for Atlanta properties with views worth showcasing.
This FAQ answers the most common questions from homeowners considering these luxury pool features.
Understanding the Terminology
Q: What is a negative edge pool?
A negative edge pool (also called vanishing edge or infinity pool) has one or more sides where water flows over the edge into a catch basin below. The edge appears to disappear, creating a stunning visual effect.
This design is particularly popular among luxury pool builders in Metro Atlanta for properties with:
- Hillside or elevated locations
- Golf course or lake views
- Wooded backdrops
- Any view worth emphasizing
Q: What is a perimeter overflow pool?
A perimeter overflow pool (also called slot overflow or knife-edge pool) has water that flows over ALL edges into a hidden channel around the entire perimeter. The water surface sits perfectly level with the pool coping.
This creates a mirror-like, ultra-modern appearance — the water appears to have no containment at all.
Q: What is the difference between infinity edge and negative edge?
These terms are interchangeable. Both refer to pools where water overflows one or more edges into a catch basin. Some Atlanta pool builders use "infinity" while others prefer "negative edge" or "vanishing edge" — the construction is identical.
Cost and Construction FAQs
Q: How much does a negative edge pool cost in Atlanta?
Adding a negative edge to a custom pool in Atlanta typically adds $20,000 - $50,000+ to base construction costs. Variables include:
- Edge length: Longer vanishing edges cost more
- Drop height: Greater elevation changes require larger catch basins
- Site conditions: Hillside construction adds complexity
- Finish materials: Premium tile edges vs. standard coping
For a typical infinity pool in Metro Atlanta, expect total project costs of $150,000 - $300,000+.
Q: How much does a perimeter overflow pool cost?
Perimeter overflow pools are the most expensive pool type, typically adding $40,000 - $100,000+ to base construction. The hidden channel system around the entire perimeter requires extensive engineering and precise construction.
These pools are most common in ultra-luxury properties where the dramatic aesthetic justifies the investment.
Q: Why are negative edge pools more expensive?
The cost increase reflects real construction requirements:
- Catch basin: A secondary pool structure must be built below the overflow edge
- Additional plumbing: Water must be pumped from catch basin back to main pool
- Larger pumps: Higher flow rates needed to maintain the overflow effect
- Precise leveling: The edge must be perfectly level for even water flow
- Auto-fill systems: Evaporation is higher and must be automatically compensated
Q: How does negative edge pool construction work?
Experienced swimming pool builders in Atlanta GA follow this sequence:
- Site engineering: Precise surveys establish elevation and catch basin requirements
- Excavation: Both main pool and catch basin are excavated
- Steel and plumbing: Rebar and circulation plumbing for both structures
- Gunite application: Main pool and catch basin shot as integrated structure
- Edge construction: Precise weir (overflow edge) formed and finished
- Equipment installation: Larger pump systems with check valves and auto-fill
- Finishing: Tile, coping, and interior finish application
Design and Planning FAQs
Q: Does my property work for an infinity pool?
Negative edge pools work best on properties with:
- Natural slope away from the home
- Views worth emphasizing (treeline, golf course, lake, city)
- Sufficient space for the catch basin behind/below the edge
- Adequate budget for the construction premium
A pool design consultation with an experienced luxury pool builder in Georgia can assess your property's potential.
Q: Which edge should be the vanishing edge?
The overflow edge should face:
- The best view from inside the pool
- Away from primary entertaining areas (catch basin noise)
- The natural downslope of your property
Most Atlanta negative edge pools place the vanishing edge at the far end from the house, maximizing the visual effect from indoor living spaces and the pool deck.
Q: Can I have multiple vanishing edges?
Yes. Two-sided and even three-sided vanishing edges are possible, though costs increase substantially. Custom pool construction in Atlanta can accommodate virtually any design vision.

Operation and Maintenance FAQs
Q: Are infinity pools hard to maintain?
Negative edge pools require slightly more attention than standard pools:
- Water level monitoring: Auto-fill systems must function properly
- Catch basin cleaning: Debris collects in the basin and needs regular removal
- Pump maintenance: Higher flow pumps require proper maintenance schedules
- Edge inspection: The weir should be checked seasonally for deposits
Our partnership with The Pool Butler ensures infinity pool owners receive specialized maintenance for these systems.
Q: Do negative edge pools use more water?
Yes, moderately. The constant water flow and larger surface exposure increases evaporation by approximately 20-30%. Auto-fill systems compensate automatically, but you will notice slightly higher water bills.
Q: Do infinity pools use more electricity?
Yes. The larger pump required to maintain overflow flow consumes more electricity than standard pool pumps. Variable-speed pumps help manage costs — running at lower speeds except during active use.
Expect 15-25% higher electrical costs compared to a standard pool of similar size.
Q: How loud is the overflow waterfall?
Water noise varies with edge design and drop height. Most Atlanta pool builders design catch basins to minimize splash noise, but some sound is inherent. Many homeowners appreciate the ambient water sound.
During your pool design consultation, discuss noise expectations and positioning relative to outdoor living areas.
Making Your Decision
Q: Is a negative edge pool worth the extra cost?
For the right property, absolutely. Negative edge pools deliver:
- Dramatic visual impact that standard pools cannot match
- Enhanced views from inside and around the pool
- Significant property value increase
- Daily enjoyment of resort-quality design
However, if your property lacks views or significant elevation change, the premium may not be justified.
Q: Should I choose infinity edge or perimeter overflow?
Consider perimeter overflow if you want:
- Ultra-modern, minimalist aesthetic
- Mirror-like water surface appearance
- Level deck-to-water transition
- Budget flexibility for the highest-end option
Choose negative edge if you want:
- Dramatic view enhancement
- Classic infinity pool appearance
- Lower construction premium
- Simpler long-term maintenance
