Custom Inground Pools in Bethesda, MD

Custom inground pools make the most sense where a stock shape will not fit. In Bethesda that is common: a back yard bounded by setbacks on three sides, a mature tree you want to keep, a slope that drops toward the rear lot line, or a house addition that left an odd-shaped patch of lawn. A custom design starts from those limits and works inward, so the final pool uses the space well instead of fighting it.

Starting with measurements, not a catalog

Our first visit is a survey of the yard. We locate property lines from your plat, measure the house, patio and existing structures, note tree trunks and drip lines, and check how the ground falls. We also walk the path from the street to the back yard, because an excavator, dump trucks and possibly a concrete pump or crane all have to get in. On older Bethesda lots, a 9-foot side yard or a retaining wall can rule out some build methods before design even begins.

Choosing the shape and depth

Geometric pools, rectangles or rectangles with a rounded end, are a common choice here because they suit Colonial and Tudor architecture and make the most of a narrow yard. Freeform shapes work on larger lots in Potomac or where the landscape is more natural. Depth is a lifestyle choice: a flat 3.5- to 5-foot pool is better for volleyball, lap swimming and young kids, while a deep end needs more length and excavation and usually raises the cost. A sun shelf or a wide entry step adds a shallow lounging area without enlarging the footprint much.

Building the spa, equipment and fence into the plan

A spa attached to the pool shares plumbing, heater and excavation, and HomeGuide's inground pool guide prices a spa built alongside the pool at $6,000 to $15,000, less than adding one afterward. The equipment pad needs its own spot, inside zoning setbacks, where noise will not bother you or the neighbors and where an electrician can bring power. The 60-inch barrier DPS requires also has to go somewhere: we draw the fence line and gate swing at the design stage so it frames the space instead of cutting through it.

Gunite or fiberglass for a custom pool

Gunite (sprayed concrete over a steel cage) is the usual choice for a fully custom pool because it can be any size, shape or depth and can include built-in benches, spillover spas and vanishing edges. Fiberglass shells are factory-made in fixed shapes, so they are custom in their placement and finish rather than their form. Many Bethesda designs end up gunite because of the odd dimensions, but if a standard fiberglass shape fits and access allows a crane, it can save weeks.

Permits and sequencing

Custom work has to match the approved site plan. DPS has said that if a pool's orientation, location or equipment changes during construction, the owner should come back to confirm setbacks, and one pool had to be moved after a change pushed it over a line. We lock the design before filing, then build in sequence: Miss Utility locate, sediment controls, excavation, steel and plumbing, bonding inspection, shell, deck bonding inspection, coping and decking, barrier, fill and final.

Planning for the long term

A pool lasts decades, so think about how you will use it in ten years: will kids outgrow a shallow play pool, will you want a heater for spring swimming, would an automatic cover replace door alarms and cut heat loss? Each is listed as a separate option on the quote with its own price.
