Quick answers about this design

Worked out from this design's own model, so they differ from page to page.

How much water does this pool hold?
About 17,500 gallons. It is 40 by 20 ft with about 640 sq ft of water, 3.5 ft deep at the steps and 6 ft at the deep end. The gallons come from adding up the depth over the real floor, steps and shelf included.
How big a yard does it need?
Plan on a clear area of about 58 by 47 ft for the pool, the tub, 4 ft of deck around the water and 5 ft to the fence line. The deck as drawn here is about 60 by 49 ft.
What does this design cost?
A planning range for FL is $125,000 to $320,000 all in: the pool, deck, coping, fence and features listed on this page. Permits and engineering are not in it. It is a range built from published prices, not a quote, and real jobs usually land inside it rather than on its edges.
How long does it take to build?
Plan on about 3 to 6 months from a signed contract to the first swim. Permits take from a few days to several months, depending on the town, before work starts.

The design

What is in this pool, and how it turns in 3D.

The design, spelled out

Every choice in this pool, what it is, and why it suits this house and this part of the country.

Depth profile

The floor is 3.5 ft deep at the steps and stays level for about 11 ft, slopes over about 14 ft, then runs level at 6 ft for the last 15 ft. A sun shelf sits at the other end.

Design notes

Written with AI tools from this design's own measurements and sources, not by a pool builder. How we write

Why it works here

Big lots let the freeform shape stretch, with the loungers on the sun shelf and the round tub on the far side. Travertine stays comfortable underfoot in Gulf sun. The cabana and outdoor kitchen sit close enough that the family can eat without leaving the water for long, while the rock waterfall and bubblers share the soundtrack.

What to watch

This design has no fence, and a pool with a family around it will need a barrier or alarm the town accepts. Ask the town before you fall for the open look.

How it reads

Tan pebble with sea glass tile gives the freeform pool a soft, sandy green that sits easily beside the pale blue house and the palms. Travertine coping and deck keep the whole edge light and warm. The rock waterfall and the round tub add a natural, tumbled look, so nothing feels like a straight line. In midday sun the pebble glitters, and as the light drops the water turns a deep, soft aqua.

Through the year

Naples has long, warm days, so the pool is a daily habit for most of the year. Summer afternoons bring storms, and sea grapes and palms drop fruit and fronds into the water. Keep the rock waterfall and the bubblers on a timer, skim the shelf near the loungers, and check the pump basket after any storm.

Every choice, row by row (15)
ShapeFreeform

A pool with natural, flowing curves. Curves relax a yard and work with planting, a rock feature or a tub, at the cost of a more complicated cover.

Size40 × 20 ft

A pool about 20 ft wide and 40 ft long. A big pool for swimming and entertaining, which needs a generous lot and a strong filtration plan. That is about 640 sq ft of water and about 17,500 gallons.

StepsCurved steps

Curved, wedding-cake steps. A formal, graceful way into a Roman or larger pool. The steps lead into water 3.5 ft deep.

Sun shelfWith loungers

A sun shelf sized for chairs in the water. Lets you sit in the cool water in the sun with a drink, which is why it works well in a hot climate.

Hot tubSpills into the pool, 7 ft round

A hot tub built into the pool and level with the deck, spilling into it. It shares the pool's water and equipment, so one heater and one set of chemistry cover both. The tub holds about 850 gallons.

Pool finishPebble

An exposed pebble aggregate finish, in the Pebble Tec style. Durable and textured, which hides small marks, but rougher on bare feet. Warm, humid water grows algae faster, so a smooth, dense finish is easier to keep clean.

Finish colorTan finish, sandy turquoise water

A tan interior. Gives a green-blue lagoon look.

Waterline tileSea glass

Sea-green glass mosaic at the waterline. A soft, coastal line that warms the water. It runs about 98 linear ft around this pool.

CopingTravertine

Ivory travertine with a rounded edge. Stays cooler underfoot than most stone and gives a warm, classic edge. It runs about 98 linear ft around this pool.

DeckTravertine pavers

Ivory travertine pavers. Light and cool underfoot, and a natural fit with Mediterranean and French styles. The deck is about 2,140 sq ft here. Choose a texture that stays safe when wet, because this deck will be damp often.

PlantingTropical

Palms, bird of paradise and big-leaf plants. Creates a resort feel and screens the neighbors in a warm, humid climate. Choose planting that tolerates storms and keep it a few feet from the water to limit debris.

Water featuresBubblers, Rock waterfall
  • Bubblers: Small domes of water rising on the sun shelf. A soft sound and a cooling touch on a shelf, with little plumbing.
  • Rock waterfall: A natural rock waterfall. Gives a lagoon look and a strong sound, and uses more space than a wall feature.
Add to the yardCabana, Outdoor kitchen
  • Cabana: A small, open-sided cabana beside the pool. A shady place to change, nap or stash towels. It needs a footing and often a permit.
  • Outdoor kitchen: An outdoor kitchen with a built-in grill and counter. Keeps the cook near the pool. It needs gas or power, water and a drain, and usually a permit.
FurnitureLoungers, Umbrella, Dining table
  • Loungers: A pair of chaise loungers. The first thing people want on a pool deck.
  • Umbrella: A market umbrella. Cheap shade that you can move with the sun.
  • Dining table: An outdoor dining table and chairs. Turns the pool into the place where meals happen.

Why it fits the large estate

The yard: a large manicured lot with queen palms, sea grapes and a golf course fairway fading into the distance. An estate lot can hold a large pool, so the design is about scale, views and a place to gather. Space lets the pool, the pergola, the outdoor kitchen and the lawn each have room. The risk is a pool that looks lost, so scale the deck and the planting with the house.

Why it fits the coastal house

The house is a sprawling pale-blue coastal estate with white trim, a standing-seam metal roof and deep porches. A coastal house wants light colors, natural wood and a view that stays open. A clean rectangle, a glass fence, pale coping and a wood-look deck keep the yard bright and let the ocean air and light do the work.

Will it work for you

Your yard, your climate, and what the pool asks of you after the build.

Will this fit your yard?

A planning estimate, built from the model's own dimensions. Your town's setbacks decide the real answer.

Clear area to plan on

58 × 47 ft

About 2,726 sq ft. The pool and tub alone is 40 × 28.5 ft.

Plan on a clear area of about 58 by 47 ft for the pool, the tub, 4 ft of deck around the water and 5 ft to the fence line. The deck as drawn here is about 60 by 49 ft.

The 4 ft walkway and 5 ft setback are our planning allowances, not code. Towns set their own distances from the water to the lot line and the house, so ask yours before you commit to a layout.

Florida: what the climate asks of this pool

A Florida pool is used most of the year, so heat, storms and screens shape the design.

  • Many Florida pools sit under a screen enclosure, which keeps out bugs and leaves but changes how much sun and breeze the deck gets. Plan planting and furniture around the cage lines.
  • Afternoon storms and hurricane season mean equipment pads, pergolas and loose furniture need to be anchored or easy to stow.
  • A high water table is common near the coast. Builders usually fit a hydrostatic relief valve so the shell does not float when the ground is saturated.
  • Near salt water, salt air is hard on metal fences, light fittings and some stone. Ask which materials are rated for it.

Keeping it up

What this pool asks of its owner, by finish, climate, deck and feature.

  • Pebble in this climate

    Warm, wet weather feeds algae. Pebble's texture gives algae something to hold on to, so brush it and keep the sanitizer steady.

  • When it is resurfaced

    Pebble is usually redone every 15 to 20 or more years, depending on the water and the builder (Shasta Pools, plaster versus pebble and Pebble Technology, support). On this pool that is about 1,000 sq ft of interior.

  • Travertine pavers deck

    Seal the travertine as the maker says and rinse it after salt or chlorine splashes. Use a stone-safe cleaner, never an acid wash.

  • Rock waterfall

    A rock waterfall collects algae and leaves in the crevices. Plan on a spring clean and a check of the pump.

  • Bubblers

    Bubblers are low upkeep. Check the nozzles for scale and keep the shelf free of debris.

  • The hot tub

    A hot tub is a second body of water with its own chemistry. Keep it covered between uses and drain and clean it on the maker's schedule.

  • Algae and storms

    Warm, damp weather grows algae fast, so keep the sanitizer steady and circulation running. Secure loose furniture before a storm.

  • Yearly running cost

    Owners commonly budget $3,000 to $5,000 a year for chemicals, power, service and repairs (HomeAdvisor, in-ground pool cost, 2026).

Cost and timeline

A sourced range to plan with, and how long it takes.

What this design costs: a planning range

Built line by line from this design's own measurements and published prices. It is a range to plan with, not a quote.

Planning range, FL

$125,000 to $320,000

Everything on this page, built: the pool, the deck, the coping, the fence and the features. It is a range, not a quote. Every line is at its lowest published price for the low end and its highest for the high end, so a real job lands inside it rather than on an edge.

Prices are scaled for FL by a damped regional factor of 1.02 (the state's cost of living is 103.4 against 100 for the US, and we use half the gap). Land clearing, landscaping beyond what is listed, a pool house's interior and financing are not in it.

Outdoor kitchen
$6,000 to $27,000
A built-in outdoor kitchen.
How we built this range, and the sources

We measure this design in the 3D model (water area, shell area, coping, deck, tub, what stands on the deck), multiply each quantity by a published price range per unit, add the lines and scale them for the state. The prices are from the pages below, collected in October 2026. Where two sources disagree the range spans both, and the line says so.

The method is written out, with every rate, at docs/POOL-IDEAS-COST-MODEL.md in our repository, and one file holds the rates, so a change of price changes every page at once.

How to get a number you can trust

Ask two or three local builders to quote the same scope in writing: the pool, the deck, the fence, the electrical, the permits and the landscaping, each on its own line. Then compare the lines, not the totals. Share this page with them: the size, the choices and the 3D model give a builder a starting point. To see how the published prices are built up and where they disagree, read inground pool cost, line by line.

How long it takes to build

From a signed contract to the first swim, before the yard additions.

Contract to first swim

3 to 6 months

Permits take from a few days to several months, depending on the town, before work starts. Weather, inspections and the builder's schedule move every date.

  • The yard additions are usually built after the pool is finished, so they add weeks that are not in this range.
  • The hot tub is built with the pool, so it adds days of plumbing and tile rather than weeks.

What it is made of

The materials list for this design, with its own quantities from the model.

The materials list (10 lines)
InteriorPebble, tanabout 1,000 sq ft of shell
Small stones set in cement. It is textured, hides wear and holds color well, and it is rougher on bare feet than the other finishes.
Waterline tileSea glassabout 98 linear ft, 10 in. band
Sea-green glass adds color without matching the water, and it needs the same regular wipe as any glass tile.
CopingTravertineabout 98 linear ft
Natural stone with a rounded edge. It stays comfortable underfoot but should be sealed, and it needs a gentle cleaner rather than an acid wash.
DeckTravertine paversabout 2,140 sq ft
Natural stone pavers. Cooler than most paving in the sun, but porous: it needs sealing and a quick rinse after salt or chlorine splashes.
PlantingTropical
Palms, big leaves and lush planting. It needs water, wind and cold protection, and it drops leaves in the pool.
Water featureRock waterfall
A natural stone waterfall. It needs space, a strong base and a pump sized for the flow, and it is the feature that most changes how the yard looks.
Water featureBubblers
Small domes of water on the shelf. They are quiet, they run on the pump or a small one of their own, and they take little room.
Yard additionCabana
A small open-sided shelter beside the pool: shade, a changing spot and somewhere to keep towels.
Yard additionOutdoor kitchen
A built-in grill and counter. It needs gas, power and drainage run to it, and a spot away from the water.
Hot tubSpills into the pool, roundabout 850 gal
Built with the pool, with its own jets, heater share and cover. Tile and coping match the pool.
