A mid-size gunite pool (about 16×32) with a standard plaster finish in Rockville typically runs $86,500–$138,000. Spas, premium finishes, features and decking are where custom pools climb from there:
| Job | Typical Rockville price |
|---|---|
| Small gunite pool (about 12×24), plaster finish | $63,000–$92,000 |
| Mid-size gunite pool (about 16×32) | $86,500–$138,000 |

| Attached gunite spa with spillover | $17,500–$40,500 |
| Pebble or quartz finish upgrade | $6,000–$14,000 |

| Water features, lighting, fire bowls | $2,500–$17,500 |
| Decking and coping | $9,000–$28,500 |
| Rock or hard-dig excavation allowance | $3,500–$17,500 |
| Permits, engineering, soils report | $900–$4,600 |
Maryland pricing is above the national baseline used for these estimates, mainly on labor and permitting. Gunite bids vary more than any other pool type because every element is custom — compare the shell thickness, steel schedule, finish, feature and equipment lines, not just the bottom number.
Spas, ledges, benches, lighting niches and water features are cheapest when they are shot into the shell — adding them later means cutting concrete.

Piedmont clay west of the Bay needs good drainage and properly compacted backfill; the Eastern Shore has sand, high water tables, and hydrostatic planning. Sloped Montgomery and Baltimore County lots often add retaining walls, while mature-tree suburbs make access and root management part of the bid. Gunite with spas and paver decks leads the DC-side counties; vinyl liner holds strong value share elsewhere. Salt systems, heat pumps, and automatic covers are all mainstream, and compact luxury builds are rising on smaller infill lots.

Ask for the shell engineering and the gunite crew's track record, read the structural, finish and equipment warranties separately, and compare at least three itemized bids for the same design. Maryland licenses home improvement work through MHIC — verify the license number and insurance before signing. County permitting (and it varies meaningfully county to county) covers the pool, electrical, and residential-code barrier requirements; waterfront lots can add critical-area review. Builders who work your county weekly will quote realistic timelines.
A mid-size gunite pool with a plaster finish in Rockville, MD typically runs $86,500–$138,000; small pools run $63,000–$92,000 and large custom designs $138,000–$287,500+. An attached spa adds $17,500–$40,500, a pebble or quartz finish $6,000–$14,000, and decking $9,000–$28,500.

Both are concrete sprayed over a steel cage. Gunite is a dry mix with water added at the nozzle; shotcrete is wet-mixed concrete pumped through the hose. Each produces a strong shell when applied by a good crew — the nozzleman's skill, the mix design and proper curing matter more than which method is used. Ask which your builder uses and what thickness is specified.
Plan on eight to sixteen weeks from excavation to swimming: dig and steel in the first week or two, the shell shot and cured for about four weeks, then tile, coping, plumbing, equipment, decking and finally the plaster and fill. Permits add two to eight weeks before the dig. Freezing weather pauses shell and plaster work, so most builds are scheduled for the warm months.
The concrete shell can last 50 years or more. The plaster finish lasts about 10 to 15 years (quartz and pebble 15 to 20 or more), waterline tile and coping 15 to 25 years, and equipment 8 to 15 years. Balanced water, especially calcium hardness and pH, is what protects the finish.
The outdoor season in Rockville runs mid-May through September — about 4 months unheated. A full professional winterization each fall protects plumbing and equipment through the freeze, and spring openings cluster into the same few weeks. Mid-May through September, humid through the middle and stretched by heaters on both ends. Winters freeze properly, so a full close remains the standard even in milder Bay-side microclimates.

Usually, for the same size: the shell is built on site, the finish is a separate trade, and custom features add up. The gap narrows for large pools and designs with spas and ledges, where fiberglass models are limited. Over 20 years a gunite pool also needs at least one resurfacing, which is part of its true cost.
