How much does an infinity pool cost in Maryland?

The Short Answer: Add $15,000–$40,000 to Your Base Pool Cost

Infinity (vanishing edge) pools cost more than standard in-ground pools because of the precision engineering required for the edge detail, the catch basin, and the recirculation system. Expect to add $15,000–$40,000 to your base pool cost for a properly engineered vanishing edge. The total project cost for a Maryland infinity pool — pool, edge, deck, and equipment — typically runs $120,000–$250,000+ depending on size, lot, and finishes.

What Makes an Infinity Pool More Expensive

A vanishing edge pool is not just a regular pool with one wall cut lower. It requires several engineering elements that a standard pool does not:

• The vanishing edge wall: The edge wall must be engineered to an extremely precise elevation — typically within ¼ inch — so water flows evenly across the entire edge without dry spots or overflow irregularities. This requires careful surveying and precision concrete work.
• The catch basin: Water flowing over the edge falls into a catch basin (also called a balance tank or surge tank) below the edge. This basin must be sized to capture the volume of water in the pipeline and handle surge during heavy use. It adds significant excavation and concrete cost.
• The recirculation pump system: A separate pump is required to move water from the catch basin back to the main pool. This is in addition to the standard filtration pump. The recirculation system must be sized for the volume of water moving over the edge and the elevation difference between the pool and catch basin.
• Additional plumbing: Return lines between the catch basin and the main pool add significant linear footage of plumbing, increasing both material and labor costs.
• Precision deck and coping at the edge: The coping at the vanishing edge is a finished architectural detail, often in natural stone, that must align perfectly with the pool’s water line. Any variation in elevation is visible and aesthetically unacceptable.
• Structural requirements: The edge wall is a cantilevered structural element. On sloped lots, the pool shell may also require additional engineering to account for uneven soil bearing on the high and low sides of the excavation.

When Is a Maryland Lot Right for a Vanishing Edge?

An infinity pool works best when there is a natural grade drop — or an engineered one — on the side where the edge will be. The visual effect requires sightlines beyond the edge: water appearing to merge with a distant view. The ideal Maryland conditions are:

• Waterfront properties: Lots along the Chesapeake Bay, Severn River, Spa Creek, or Eastern Shore tidal water where the pool edge can align with the water view are the classic Maryland infinity pool setting. The visual effect of water appearing to flow into the Bay is genuinely dramatic.
• Elevated lots with a view: Properties on elevated ground overlooking a wooded valley, golf course, or distant landscape work well. Howard County and parts of Anne Arundel County have elevated lots that create this condition without waterfront access.
• Engineered grade changes: On lots where the grade has been deliberately created (retaining walls, terracing), a vanishing edge can be designed into the grade change. This adds retaining wall cost on top of the edge premium but can produce the effect on lots that are not naturally sloped.
• Lots that don’t work: Flat lots with no view beyond the pool edge. The vanishing edge effect requires something to “vanish” into — a flat suburban lot where the edge looks directly at a fence or neighbor’s yard produces a disappointing result and does not justify the additional cost.

Infinity Pool Cost Breakdown for Maryland

• Vanishing edge engineering premium over a standard pool: $15,000–$40,000 depending on edge length, catch basin size, and recirculation system complexity
• Total project cost for a 16×32 infinity pool with paver deck: $130,000–$175,000
• Total project cost for an 18×36 infinity pool with spa, natural stone deck: $180,000–$260,000
• Additional cost if significant grading or retaining walls are required: $15,000–$60,000 on top of the above ranges

These are realistic ranges for Maryland projects. Wade does not publish fixed prices because every infinity pool project is site-specific — the lot, the view, the edge length, and the basin design all affect cost.

One-Edge vs. Two-Edge Infinity Pools

Most residential infinity pools have a single vanishing edge on the side with the view. Two-edge (corner) vanishing pools — where water flows over two adjacent walls — are more dramatic but significantly more expensive because the catch basin must be sized for double the water volume and the recirculation system is more complex. Wade has built both configurations.
