Infinity Edge & Custom Pool Features

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.

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:

1. The weir — the precisely leveled edge over which water flows; must be engineered to exact elevation across its full length
2. The catch (surge) basin — a hidden reservoir below and behind the vanishing edge that collects the overflowing water
3. 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
4. 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.

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.

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

In the DMV area, a constructed water feature wall — a built vertical wall with water sheeting down its face through a sheer descent, scuppers, or a rain curtain — typically runs $15,000 – $25,000+. The range is driven by the wall's height and length, the facing material (stone veneer, tile, or porcelain), the number of scuppers or the width of the sheer-descent, and whether integrated LED lighting is included. It's most cost-effective when designed into the gunite shell from the start, since the structure, plumbing, and catch trough are built with the pool rather than retrofitted.

Yes — a water feature wall is one of the more retrofit-friendly premium features, because it's built adjacent to the pool rather than into the original shell. The most efficient time to add one is during a larger pool renovation, when the pool is already drained and the crew is on-site for resurfacing, coping, or decking work — combining the scopes saves mobilization cost. The wall still needs its own footing, dedicated plumbing, and a catch trough engineered for the flow, so it's a planned construction item, not a drop-in accessory. We'll assess your deck layout and equipment capacity and put the scope in writing.
