Choose the pool experience before choosing the equipment.
The edge, entry, spa, hydraulics, heating, lighting and deck must be designed together. Equipment should be sized from the actual water volume and features—not selected by brand popularity alone.
Infinity edge vs. zero edge
| Type | What you see | What it requires |
|---|---|---|
| Infinity / vanishing edge | Water appears to disappear over one or more edges toward a view. | Catch basin, balance tank/volume, second hydraulic system, waterproofing and precise edge elevation. |
| Perimeter overflow / zero edge | Water meets the surrounding deck plane and overflows around much or all of the perimeter. | Level perimeter, concealed gutter, surge capacity and careful deck/drainage detailing. |
| Beach entry | A sloped walk-in entry instead of steps at one area. | More pool footprint, slip-resistant finish and careful depth/transition design. |
| Traditional skimmer pool | Water sits below the coping and enters wall skimmers. | Simpler hydraulics, correct skimmer placement and normal water-level management. |
Pool and spa equipment
- Variable-speed pump: programmed for filtration, heating, spa jets and water features at different flow rates. Size from hydraulic calculations, not horsepower alone.
- Filter: cartridge, sand or diatomaceous-earth systems have different filtration, cleaning and water-use characteristics.
- Sanitation: chlorine feeder, salt-chlorine generator, UV/ozone supplemental systems and automation require a complete water-care plan.
- Gas heater: useful when fast heat-up is important.
- Heat-pump heater: efficient for maintaining temperature in suitable weather, but usually slower and sensitive to air temperature.
- Solar thermal: can reduce heating energy when roof/site and usage pattern fit.
- Automation: coordinates pump speeds, valves, heater, spa mode, lighting and water features.
Spa jets and color-changing lights
Jet performance depends on pump flow, pipe sizing, number/type of jets, air induction and balanced plumbing. More jets do not guarantee a stronger spa. Underwater color-changing LED lights should be listed for pool/spa use, placed to limit glare, coordinated with automation and designed with service access.
Outdoor concrete finishes
| Finish | Appearance | Best question |
|---|---|---|
| Broom finish | Linear texture made while concrete is plastic. | How coarse will the broom be and in which direction? |
| Sand finish / sand wash | Fine aggregate texture with a softer, refined appearance. | What sample panel, sealer and slip resistance are specified? |
| Exposed aggregate | More stone is intentionally revealed. | What aggregate color/size and exposure level? |
| Smooth or hard-trowel | Minimal surface texture. | Is it appropriate and slip-resistant for this outdoor/wet location? |
| Integral color | Pigment is mixed through the concrete. | How will batch variation, curing and sealer change the final color? |
| Topical stain / “blue” or custom color | Color treatment applied to or near the surface. | Is the named finish a contractor-specific sample rather than a universal industry standard? |
“Blue finish” is not one universal specification. Require a labeled physical mockup showing mix/color system, texture, joints and sealer. Approve it in exterior light and understand that concrete naturally varies and can crack.
Pool cost questions to answer first
Geometry, excavation/access, soils, retaining walls, infinity/overflow systems, spa, finish, coping/deck, equipment, utilities, automation, landscape restoration and permits drive cost. Obtain a soils/site review and concept plan before relying on a budget from length × width.
Design the pool as part of the property
DG Builders can coordinate pool, structural, drainage, utilities, hardscape and outdoor living into one construction sequence.
