Most homeowners will never see the parts of a pool that matter most after the water goes in. The shell is covered by the finish, the plumbing is buried, and the steel is no longer visible. That does not make those decisions mysterious. It means the right pre-construction questions are worth asking before a proposal becomes a contract.
For the broader build-planning framework, explore our Pool Construction guides and our Pool Permits in Pennsylvania guide.
- Gunite and shotcrete are placement terms, not automatic quality grades. Dry-mix and wet-mix can both produce quality concrete when the design, materials, crew, placement, and curing plan are right.
- The shell should follow an engineered plan. Ask how the builder will address shell thickness, reinforcement layout, concrete cover, water features, soil conditions, and inspection—not just a single rebar-spacing number.
- Hydraulics should be designed around the actual pool. Plumbing, pump selection, filtration, returns, features, equipment access, and automation need to work together rather than being treated as disconnected allowances.
- Use the proposal to learn how the work will be checked. A clear builder should explain the scope, the sequence, the documentation, the owner decisions, and who is responsible for answering questions at each phase.
The Straight Answer: A Better Build Starts Before the Dig
A quality custom pool is not one product or one line item. It is a coordinated construction process: site planning, permits, excavation, structural design, steel, shotcrete placement, plumbing, equipment, finish work, safety details, startup, and owner training. Each phase affects the next one. The homeowner does not need to become an engineer to evaluate that process, but you should be able to understand what is being proposed and why.
That is especially true when two proposals use similar words but describe different scopes. “Gunite pool,” “premium equipment,” or “custom design” can mean very different things unless the plans and allowances show the materials, responsibilities, options, exclusions, and inspection steps behind those labels. The useful question is not which sales presentation sounds best. It is whether a builder can explain the work in plain language and document the choices that affect your property.
Scott Payne Custom Pools approaches the construction conversation by starting with the site and the owner’s priorities. A sloped yard, attached spa, multiple water features, mature trees, access restrictions, a tight equipment area, or a particular finish can all change the right technical approach. The goal is to make the tradeoffs visible before construction begins—not to overwhelm a homeowner with jargon after a decision is already locked in.
Gunite, Shotcrete, and the Words That Matter
“Shotcrete” describes a concrete-placing process in which material moves through a hose and is projected at high velocity onto a surface. The American Shotcrete Association distinguishes two common methods. In dry-mix shotcrete, most mixing water is added at or near the nozzle; “gunite” began as a trade name for this dry-mix process. In wet-mix shotcrete, the concrete, including water, is mixed before it enters the delivery hose and compressed air is introduced at the nozzle.[1]
Those definitions are important because they eliminate a misleading shortcut: dry-mix and wet-mix are not opposite categories of “good” and “bad.” The American Shotcrete Association states that both are placement methods for concrete and that either can produce quality concrete with proper materials, equipment, and placement.[2] A homeowner should be cautious when a proposal reduces the entire structural conversation to one method name.
What to Ask About the Shell
Ask which placement method is proposed, who will perform it, how the mix and placement plan are specified, and what quality-control process will be used on your job. The answer should make sense for the design, access, schedule, weather, and engineering requirements of the project. It should also identify who is responsible for observing the shell work and how questions will be handled if site conditions differ from the original plan.
Compressive strength is another example of why context matters. The American Shotcrete Association describes 4,000 psi at 28 days as a recommended minimum for pool shotcrete, while also noting that the required strength depends on the pool design.[2] That is a useful homeowner benchmark, but it is not a substitute for project-specific structural design. A responsible contractor should be prepared to explain the performance criteria and the role of any engineer or plan set involved in the work.
Why Rebound Deserves a Question
During shotcrete placement, some material can bounce away from the receiving surface. The industry calls that material rebound. The American Shotcrete Association defines rebound as material with inadequate cementitious content compared with the original shotcrete.[1] Rather than turning that definition into a dramatic sales claim, use it as a practical question: how will the crew keep loose material out of structural work and how will the work area be managed during placement?
A good answer should be specific enough to show that the builder understands the process, but it does not need to be a theatrical promise. What matters is a documented plan, experienced placement personnel, appropriate preparation, and a clear quality-control conversation. The same principle applies to curing: young concrete needs an appropriate curing plan, and the ASA notes that curing helps control shrinkage issues and supports the concrete’s potential strength.[3]
Steel, Shell Geometry, and Project-Specific Design
Reinforcing steel helps a concrete pool shell manage tensile forces and cracking considerations that concrete alone is not designed to carry. But there is no honest one-number answer to “What rebar spacing should every pool have?” Shell thickness, reinforcement layout, bar size, concrete cover, soil conditions, wall geometry, raised features, attached spas, water tables, and local requirements can all affect the design.
The American Shotcrete Association explains that concrete cover for embedded reinforcing steel is subject to applicable building codes and can be increased by plans and specifications from an engineer or architect for a specific project.[3] That is the standard a homeowner should expect: your builder should be able to explain what governs the plan for your pool, rather than treating a generic online rule of thumb as a substitute for design.
| Question to ask | A useful answer should explain |
|---|---|
| Who prepared or reviewed the structural plan? | Whether a project-specific engineering or plan-review process applies, and how the design responds to the pool’s size, shape, soils, elevations, features, and local requirements. |
| How will steel be placed and checked? | The relevant layout, clearances, supports, penetrations, and inspection steps—not an unsupported universal spacing claim. |
| How will shell changes be handled? | Who must approve a change if site conditions, elevations, access, or a selected feature affects the original design. |
| What will I receive at handoff? | The plans, specifications, warranties, equipment information, and owner guidance that help you understand the finished system. |
Steel is one part of the shell, not an isolated upgrade. Homeowners should also ask about transitions, steps, benches, raised walls, waterline details, penetrations, and any feature that changes the shell geometry. A clean proposal separates the structural work from decorative choices so you can see what is base scope, what is optional, and what requires a design decision before the work reaches the yard.
It is also reasonable to ask how the contractor coordinates steel, plumbing penetrations, and the placement crew. The answer does not need to reveal proprietary methods; it should confirm that the systems are coordinated and that someone is responsible for resolving conflicts before they become buried work.
Hydraulics: Design the Whole Water System
Pool hydraulics is simply the way water moves through the system. The pump draws water through suction points, pushes it through filtration and treatment equipment, and returns it to the pool through returns and features. That system has to account for pool volume, plumbing size and length, elevation, valves, filtration, water features, cleaners, heating, automation, equipment location, and the intended operating schedule.
The pump is not a stand-alone purchase. Pool volume, pipe size and length, feature loads, filter capacity, equipment location, elevation, intended operating schedule, and the selected heater or heat pump all belong in the hydraulic conversation. Hayward’s variable-speed pump technical guide likewise calls for a pump location close to the pool where practical, direct suction lines to reduce friction loss, appropriate pipe and equipment sizing, space for valves, and adequate service access.[4] Hayward’s equipment-manual library spans pumps, filters, automation, heaters, lighting, water features, and sanitization, which is a useful reminder that a pool system must be planned as connected equipment—not as a list of unrelated boxes.[5] A claim about savings, noise, circulation, or “perfect pressure” should therefore be tied to the specific project rather than treated as universal.
What Good Hydraulic Planning Looks Like to a Homeowner
Look for an explanation of the equipment pad and the water path. Where will the pump, filter, heater or heat pump, controls, valves, and electrical equipment sit? Is there working space for service? How are skimmers, drains, returns, and water features being considered? How will the design accommodate an attached spa, tanning ledge, waterfall, in-floor system, salt chlorinator, or future feature if one is part of the plan?
You do not need a page of calculations in a sales meeting. You do deserve a builder who can explain why the proposed equipment package fits the pool, how circulation will be managed, and what assumptions are being made. If a proposal includes an allowance rather than a named component, ask when that decision will be finalized and whether the selection could change cost, electrical needs, service access, or lead time.
Equipment Access Is Part of Ownership
Equipment works best when it can be maintained safely. Ask whether there is room to open a filter, inspect valves, read labels, remove a pump basket, winterize lines, service a heater, and reach electrical controls. A clean-looking equipment pad is helpful, but the more important test is whether the system can be understood and serviced without dismantling other parts of the installation.
That planning matters in Pennsylvania and New Jersey, where winterization and spring startup are real ownership events. The exact procedure depends on the equipment and the project. Your builder or service professional should give you manufacturer-specific instructions and explain who will be responsible for the first closing, opening, or owner training.
Plumbing, Features, and the Details Behind the Finish
Most of the work that homeowners call “the pool” is actually a group of connected systems. The shell supports the vessel. Plumbing moves water. Filtration, treatment, and heating support water quality and comfort. Tile, coping, interior finish, decking, drainage, lighting, and safety elements all have their own materials, sequencing, and care requirements.
That is why a proposal should describe what is included rather than relying on a single “standard package” label. Ask about pipe material and the locations where different components will be used; valve and union access; penetrations for lights and features; drainage around the pool and deck; electrical scope; automation; and the approved selections for finish, tile, coping, and decking. Where a choice is still open, ask who owns the decision and what it could affect.
Interior finishes deserve the same direct conversation. A finish is both an aesthetic choice and a care consideration, but no finish makes water chemistry, circulation, cleaning, or proper startup irrelevant. Review the manufacturer’s care guidance for the product selected for your pool. If a builder recommends a particular finish, ask why it suits the design, the color goal, the owner’s maintenance plan, the water features, and the expected use of the pool.
Build Questions Are Better Than Shortcut Labels
A builder does not earn trust by promising that every alternative will fail. Trust comes from explaining the plan for your property, identifying what is included, documenting decisions, and answering technical questions without hiding behind vague allowances.
Use the construction conversation to understand the work sequence, who is accountable at each stage, and how the finished pool will be handed over to you. Those details are more useful than a generic “premium” label.
What to Watch During Construction
Homeowners should not be asked to supervise a construction crew. You hired a contractor to manage the work. But it is healthy to know the major decision points and to ask for a clear communication plan. Before the project begins, identify who you contact with a question, how change decisions are documented, what the normal update cadence will be, and when you should be available for selections or approvals.
During early work, you may see layout, access preparation, excavation, forms, steel, plumbing, and shell placement. Later, the sequence may include tile, coping, finish work, equipment startup, decking, landscaping coordination, and final owner orientation. The precise order changes with design and conditions. Your builder should explain the sequence for your specific project rather than promising a generic schedule that ignores weather, permitting, inspections, material availability, or site conditions.
Keep a written record of selections, changes, and questions. Confirm the approved finish color, tile, coping, equipment package, feature details, and any change order before related work moves forward. This is not adversarial; it is how a major custom project stays understandable for everyone involved.
A Builder-Meeting Checklist
Bring these questions to an initial meeting or proposal review. The purpose is not to trap a contractor. It is to make sure you understand the plan before you commit.

How We Help You Evaluate the Build
The right pool is not built from one stock answer. It is planned around the property, the design, the intended use, the selected features, access, service needs, and the decisions that need to be made before work begins. As a Hayward dealer, Scott Payne Custom Pools can discuss a Hayward equipment path as part of that complete system—rather than treating the pump, filtration, heat, automation, and water care as disconnected selections. Our job is to make the conversation clearer: what the proposed scope includes, what choices remain, what the build sequence looks like, and what questions should be settled before the ground is opened.
If you are comparing approaches or beginning a custom-pool conversation, start your journey with Scott Payne Custom Pools. We will discuss your yard, priorities, and the construction decisions that matter for your project—without asking you to accept a one-size-fits-all answer.
