Infinity Edge & Custom Pool Features
What We Can Build Into Your Pool
Every feature below is available when designed into your gunite pool from the start. Most cannot be retrofitted efficiently — which is why we discuss them during your first design consultation.
Infinity / Vanishing Edge
One edge of the pool sits flush with the water surface so it appears to merge with the horizon or landscape. A catch basin and return pump are engineered into the shell. Best suited for sloped lots with a view.
Tanning Ledge (Baja Shelf)
A large, shallow platform — typically 6–9 inches deep — at one end of the pool. Ideal for loungers, young children, and umbrella placement. Sized and positioned during the layout phase of design.
Beach Entry
The pool floor slopes gently from dry land into the water, replicating a natural beach approach. Requires careful grading and additional surface area in the design. Fully accessible, visually dramatic.
Water Features
Waterfalls, deck jets, bubblers, sheer descents, and grottos are integrated into the shell structure during construction. Each has specific plumbing and engineering requirements that must be specified before excavation.
Color LED Lighting
Pentair IntelliBrite and similar fixtures deliver full RGB color-changing light in the water. Niches are formed into the shell during gunite application. Outdoor and landscape lighting can be coordinated simultaneously.
Pool Automation
Full integration with Pentair IntelliCenter, Jandy iAqualink, or Hayward OmniLogic lets you control filtration, heating, lighting, and water features from a smartphone. Automation wiring is planned before the equipment pad is set.
Premium Features Are Design Decisions — Not Add-Ons
Nearly every feature on this page requires structural and mechanical decisions made before a single shovel of dirt is moved. An infinity edge requires a specific catch basin and return system engineered into the shell. A beach entry changes the surface area calculation and grading plan. Automation needs dedicated conduit runs before decking is poured.
Retrofitting these after construction is either impossible or exceptionally expensive — it typically means draining the pool, breaking out concrete, and rebuilding sections of shell.
The right time to decide on custom features is your first design consultation — before anything is finalized on paper.

Budget & Financing
Premium features typically add $15,000–$60,000+ to base pool cost
Infinity edges, water features, and tanning ledges are designed in from day one. See our cost guide and explore financing options.
What Each Feature Adds to Your Build Cost
These are incremental cost additions on top of the base gunite pool price. Features planned during design are significantly cheaper than retrofitting after construction is complete.
Includes catch basin, return pump, and edge engineering
Larger ledges and Ledge Lounger mounting add to the upper range
Slope, grading, and additional surface area are the primary drivers
Most pools install 2–6 jets; LED lit jets run higher
Natural rock waterfalls run higher; architectural sheer descents lower
Most pools need 2–4 niches; automation control adds separately

Shared or dedicated equipment; size and jet count are main drivers
All ranges reflect current DMV-area market rates. Final pricing is confirmed in your construction contract after the design phase. Combining multiple features in one build is more cost-efficient than adding them individually over time.

What Our Customers Say
April 2023
“I reviewed multiple proposals on rebuilding a pool upon the purchase of our new house. The previous owner had deferred maintenance on literally every aspect of the pool. Our pool required 100% replacement of the filtration system, heater, skimmers and reconstruction of the drainage system, pool floor, tile and coping. Beltway Pools was by far the most responsive of the bidders with the most reasonable and easiest to understand pricing. Anything that I required clarity on they provided. We now are almost a year past the initial work and they did not deviate one penny from their original pricing. They continue to support us with weekly visits (incremental cost but well worth it) for cleaning and chemical balancing. We are very pleased with our service from Beltway Pools. -Andrew T.

How much does an infinity edge pool cost?
In the DMV area, an infinity edge pool typically costs $50,000 to $100,000 more than a comparable standard pool design, due to the structural complexity, catch basin engineering, and additional equipment required. Total project costs for a well-executed infinity edge pool with premium finishes commonly run $175,000 to $350,000+. Key cost drivers include the length and height of the vanishing edge, catch basin size, recirculation pump system, site elevation change, and the finish choices for both the pool and the weir wall. Request a consultation for a site-specific estimate.
How does a negative edge pool work mechanically?
An infinity (negative/vanishing edge) pool creates the visual illusion that the water extends to the horizon by keeping the water level exactly at the rim of one or more edges, so water continuously flows over the edge rather than stopping at a conventional wall. The mechanics require:
- The weir — the precisely leveled edge over which water flows; must be engineered to exact elevation across its full length
- The catch (surge) basin — a hidden reservoir below and behind the vanishing edge that collects the overflowing water
- A dedicated recirculation pump — returns water from the catch basin back to the pool; this is a second pump system in addition to the main circulation pump
- Leveling and site grading — the pool must be positioned so the vanishing edge drops toward a meaningful view — a slope, valley, or landscape feature
The weir elevation is the most critical construction detail — it must be perfectly level across all infinity edges or the water flow will appear uneven.
Can an infinity edge be added to an existing pool?
In most cases, no — at least not practically. Adding a true infinity edge to an existing pool requires fundamentally restructuring the pool's shell and bond beam at the vanishing edge, excavating and constructing a catch basin below the edge, adding a second recirculation pump system, and re-engineering the hydraulics. The cost and disruption of this modification typically approaches or exceeds the cost of building a new pool with the infinity edge designed in from the start. The rare exception is a specific pool geometry where one wall is accessible and the site layout accommodates a catch basin retrofit economically — we'd assess this case by case. In nearly all scenarios, infinity edge is best planned during new pool design.
What custom features are most popular for high-end pools in the DMV?
Based on our project work across Northern Virginia, Maryland, and DC, the most requested premium custom features are:
- Vanishing/infinity edge — the definitive luxury statement for properties with an elevation change or view
- Tanning ledge (baja shelf) — a shallow entry ledge, 6–12 inches deep, for lounge chairs or young children
- Full automation + LED color lighting — smartphone control and dramatic color shifts at night; now nearly standard on high-end builds
- Natural rock waterfalls — custom-built architectural element; often serves as the pool's focal point
- Swim-up bar or seating ledge — in-pool bar stools at a raised shelf or sunken area for entertaining
- Outdoor kitchen and fire elements — increasingly treated as part of the pool project rather than a separate scope
