# Coastal estate lagoon pool in Naples

A big freeform lagoon with a shelf for loungers, an outdoor kitchen and a cabana for the whole family. Drawn for a sprawling pale-blue coastal estate with white trim, a standing-seam metal roof and deep porches, with a large manicured lot with queen palms, sea grapes and a golf course fairway fading into the distance.

A design idea for Naples, FL. Florida, large estate, Coastal. Updated 2026-10-06.

## The numbers

- Size: 40 × 20 ft (3.5 to 6 ft deep)
- Water surface: 640 sq ft
- Water: about 17,500 gal
- Coping: 98 linear ft
- Deck: 2,140 sq ft
- Hot tub: 7 ft round (about 850 gal)

## The design, spelled out

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.

### Shape: Freeform

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.

### Size: 40 × 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.

### Steps: Curved 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 shelf: With 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 tub: Spills 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 finish: Pebble

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 color: Tan finish, sandy turquoise water

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

### Waterline tile: Sea 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.

### Coping: Travertine

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.

### Deck: Travertine 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.

### Planting: Tropical

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 features: Bubblers, 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 yard: Cabana, 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.

### Furniture: Loungers, 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.

### Light: Midday sun

Shown in midday sun. Shows the true color of the water and the finish.

## Why it suits this house

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.

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 fit your yard?

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.

## 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.

## Quick answers

**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.

## 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 long it takes

3 to 6 months from contract to first swim. Permits take from a few days to several months, depending on the town, before work starts.

- 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

- Interior: Pebble, tan (about 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 tile: Sea glass (about 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.
- Coping: Travertine (about 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.
- Deck: Travertine pavers (about 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.
- Planting: Tropical. Palms, big leaves and lush planting. It needs water, wind and cold protection, and it drops leaves in the pool.
- Water feature: Rock 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 feature: Bubblers. 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 addition: Cabana. A small open-sided shelter beside the pool: shade, a changing spot and somewhere to keep towels.
- Yard addition: Outdoor kitchen. A built-in grill and counter. It needs gas, power and drainage run to it, and a spot away from the water.
- Hot tub: Spills into the pool, round (about 850 gal). Built with the pool, with its own jets, heater share and cover. Tile and coping match the pool.

## Keeping it up

- 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).

## Questions to ask a builder

- Which parts of this design need a hurricane tie-down, and does the screen enclosure change the pool layout?
- With a rock waterfall, bubblers and a spilling tub on one pool, how many pumps does it need and can they run on a schedule?
- Do the pool and the tub share a heater, and can the tub run alone in cold weather?
- How deep is the sun shelf, and can a chair sit on it without tipping?
- Where do the gas, power and drain for the outdoor kitchen run, and is it permitted with the pool?
