What to Consider When Designing Your Pool

Eight Decisions That Shape the Pool You’ll Live With for Decades

You may be eager to jump into pool ownership, but before the shovel hits dirt, the design phase is where the long-term value of your investment is either built in — or lost.

Thoughtfully designed pools maximize the use of the yard, accommodate the family that lives there, integrate with the rest of the outdoor space, and age well. Pools that are designed in a hurry — picked from a catalog without thinking through how you’ll actually use them — are the pools homeowners regret a few summers in.

Here are the eight factors we walk every customer through during the design phase at Seasonal World.

1. The “Who” — Who Is Going to Use This Pool?

This is the question we ask first because it shapes almost every other decision.

Examples of “who”:

• A family with young kids (safety, beach entries, shallow play areas)
• An empty-nester couple (lap-friendly geometry, spa integration, lower maintenance)
• A family that loves to entertain (swim-up bars, in-pool seating, deck space for crowds)
• A serious swimmer (length over feature integration, current systems, depth for diving)
• A multi-generational household (mixed depths, easier ingress for older swimmers)

The “who” answer drives shape, depth profile, feature priorities, and whether the pool is built for solo lap mornings or weekend birthday parties.

2. The “What” — What Is It Going to Be Used For?

Closely related, but distinct. Two families with the same makeup can use a pool completely differently.

Common “what” answers:

• Sport — basketball, volleyball, water polo
• Lounging — tanning ledges, in-pool loungers, daybeds
• Hanging out — sun shelves, swim-up seating, raised spa with view
• Exercise — lap swimming, swim-jet system, current generator
• Therapeutic — spa integration, hydrotherapy seating, warm-soak design
• Casual diving — depth requirements, slide integration
• Combination of all of the above — and this is most homeowners

The “what” determines size, depth, and feature integration. Get this wrong and the pool you wanted to swim laps in turns out to be 4 feet deep, or the pool you wanted for parties has nowhere for guests to sit.

3. Yard Dynamics

The yard speaks first. We’ve designed pools where the yard practically dictated the shape, and we’ve designed pools where the homeowner’s vision worked against the property and we had to push back.

Yard factors that drive pool design:

• Lot shape and dimensions — long-and-narrow, square, irregular, sloped
• Existing structures — the home, garage, deck, mature trees, fence lines
• Setbacks — NJ municipalities have specific setback requirements from property lines, septic, wells
• Grade — sloped yards may require retaining walls, raised pool decks, or a raised pool wall
• Soil and water table — high water table affects construction type choice (steel-wall vinyl is a poor fit; concrete vinyl liner or gunite is better)
• Sun exposure — where will the pool catch sun in summer? In spring/fall?
• Sight lines from the home — what do you see from the kitchen, the family room, the primary bedroom?

A 20×40 rectangle that works perfectly in a square back lot may be the wrong choice for a wedge-shaped yard where a freeform pool fits the contour and adds usable lawn back.

4. Size and Effective Square Footage

Size matters — but in a way most homeowners don’t think about until we explain it.

The freeform-vs-rectangle math:

A 20×40 rectangular pool is 800 square feet of swimming surface.

A 20×40 freeform pool — with the same outer dimensions but rounded corners and curved edges — is typically 650 to 750 square feet, depending on how aggressive the curves are.

That’s 50–150 square feet of effective swim area you give up for the visual softness of a freeform shape.

For some yards and some families, that trade-off is exactly right — the freeform looks better, fits the yard better, and 700 square feet is plenty. For others (lap swimmers, basketball players, families with 5+ kids), it’s a hidden cost.

The shopping tip we tell every customer: when you’re comparing pool quotes from different builders, ask for the square footage of the swimming surface, not just the outer dimensions. That’s the apples-to-apples comparison.

5. Specialty Features and Options

Features don’t get added to a pool — they’re built into the structure of the pool. Decide what you want before construction starts, because retrofitting is expensive and sometimes impossible.

Features that significantly affect pool design:

• Tanning ledges / sun shelves — reduce swim area, add lounging area
• Attached spas — the spa shares a wall with the pool (spillover edge)
• Detached spas — separate structure, often gunite, with its own equipment pad
• Raised spas — elevated above pool deck, often with sheer descents into the pool
• Rock waterfalls — built into the shell or set on the deck edge
• Sheer descents — clean linear water features off a raised wall or spa
• Bubblers — water jets that emerge from a tanning ledge
• Slides — affects shell shape, depth, and clearance
• Beach entries — gradual zero-entry transition (only works in specific shell types)
• Swim-up bars — built into the pool wall with seating on the dry side
• Negative edges — gunite-only, requires specific yard grading and a catch basin

A large sun deck either grows the overall pool footprint or shrinks the swim area. Build it into the design, not on top of it.

6. Hardscape, Coping, and Deck Materials

The pool itself is half the project. The hardscape around it is the other half — and it’s what you actually walk on, sit on, and look at most of the time.

Coping is the cap material at the pool’s edge — typically 12 inches wide, where you’d sit with your feet in the water. Options include: – Natural stone (travertine, limestone, bluestone) – Cast concrete – Brick

Deck materials at Seasonal World include: – Rinox hardscape pavers — premium concrete pavers, broad style range, color stability that holds up in NJ freeze-thaw – Del Conco porcelain pavers — the European porcelain standard. Frost-proof, stain-proof, slip-resistant, dimensionally precise. The premium pick. – Natural stone — travertine, bluestone, limestone (matched to coping) – Stamped concrete — budget-friendly, stylistically limited – Wood / composite decking — typically used as a transitional element rather than full pool surround

The coping-to-deck transition is one of the hardest details to get right. A great pool builder thinks about it the same way they think about the pool shell — at the design phase, not the punch list.

7. Outdoor Living Integration

Your pool is the centerpiece of your backyard, but it’s rarely the only piece. The pool’s design should account for:

• Pool house or cabana — siting, plumbing, sight lines from the pool deck
• Outdoor kitchen — distance to the pool, prevailing wind, smoke direction
• Fire feature — fire pit, fire bowls on a raised wall, fireplace
• Pergola or covered patio — shade location, integrated lighting
• Pool equipment pad — usually hidden, but its location affects plumbing runs and sound
• Lighting plan — pool lights, deck lighting, landscape lighting all work together

The properties homeowners love five years in are the ones where the pool, the deck, the kitchen, the fire feature, and the lighting were all planned in the same design phase — not added one at a time.

8. What 2026 Looks Like — Current NJ Backyard Trends

Pool design moves slowly compared to interior design, but a few clear trends have settled into mainstream NJ work over the last few years:

Hardscape integration over deck-and-grass

Older designs put pool, concrete deck, then lawn. Current designs treat the entire backyard as a single hardscape composition — paver patios, walkway integration, multiple seating zones, transitions to garden beds rather than lawn.

Hot tub pairings (separate from spa-on-pool)

Beyond the traditional attached spa, more homeowners are pairing the pool with a separate hot tub on the deck — typically a four-to-six-person hot tub that gets used year-round, while the pool sleeps from October to April.

Outdoor kitchens as standard, not luxury

Five years ago an outdoor kitchen was a custom add-on. Now it’s a baseline expectation in mid-tier and premium builds — built-in grill, refrigerator, prep counter, and a covered seating area.

Fire features

Fire bowls on the raised pool wall, sunken fire pit lounges off the pool deck, and fireplaces in covered patios. Fire is the strongest single design element for extending pool-deck use into the shoulder seasons.

Self-cleaning systems

Built-in floor jets that push debris to the main drain are no longer a high-end novelty — they’re the way most premium NJ pools are being built. Less skimming, less brushing, less time spent on maintenance during the season you actually want to swim. (Self-cleaning systems are a Seasonal World specialty — ask us about it.)

3D design as standard, not optional

The biggest change. Five years ago, customers picked a pool from sketches and a sample book. Now we render your pool, in your yard, in 3D — before construction. You see what it’ll actually look like from the kitchen window, from the deck, at sunset.

How We Make Design Decisions Easier

This is a lot of factors. Most homeowners haven’t designed a pool before, and they shouldn’t be expected to make all eight decisions in a vacuum.

Here’s what we do at Seasonal World:

Visit our Clarksburg, NJ Design Studio

Touch the materials. Compare liner patterns side by side. See coping options against deck options. Look at fiberglass color samples next to gunite finish samples. The showroom turns abstract decisions into concrete ones in about an hour.

See your pool in 3D before construction

We render your pool in your yard, in 3D. Different shapes, different finishes, different feature configurations — all visualized before commitment. → 3D design rendering →

Sample kits

Liner patterns, paver samples, coping samples, tile samples — physical samples we’ll bring to your home so you can see them in your light, against your house.

One team, start to finish

The team that designs your pool is the same team that builds it, services it, and stands behind the warranty. In-house Service and Warranty department, factory-trained technicians, ongoing continuing education. No subcontractor handoffs, no “that’s not our department” answers when something needs attention five years in.

Designing a Pool Starts With a Conversation

Visit our Clarksburg, NJ showroom or request a 3D design consultation. Bring a rough sketch of your yard if you have one — even a phone photo helps. We’ll talk through the eight factors above and start narrowing in on the pool that fits your family, your yard, and the way you actually plan to live in your backyard.
