# Rooftop plunge pool with a skyline view in Miami

A glass-fenced plunge on a Brickell penthouse terrace, cool underfoot and made for a sunset swim. Drawn for a glass-and-concrete high-rise with a private penthouse terrace and floor-to-ceiling sliding doors, with a roof terrace with planters of silver buttonwood and sabal palms, the Miami skyline and Biscayne Bay behind.

A design idea for Miami, FL. Florida, urban rooftop, Tropical. Updated 2026-10-06.

## The numbers

- Size: 16 × 8 ft (3.5 to 5 ft deep)
- Water surface: 130 sq ft
- Water: about 2,000 gal
- Coping: 32 linear ft
- Deck: 630 sq ft

## The design, spelled out

The floor is 3.5 ft deep at the steps and stays level for about 4 ft, slopes over about 5 ft, then runs level at 5 ft for the last 6 ft. A sun shelf sits at the other end.

### Shape: Rectangle

A rectangle with square corners. It is the simplest to build, covers neatly and fits a modern or formal house.

### Size: 16 × 8 ft

A small pool about 8 ft wide and 16 ft long. A plunge pool is for cooling off, soaking and a small yard, not for swimming laps. That is about 130 sq ft of water and about 2,000 gallons.

### Steps: Steps and a bench

Steps with a bench along one wall. Gives adults a place to sit and talk in the water while the kids play. The steps lead into water 3.5 ft deep.

### Sun shelf: Sun shelf

A shallow ledge a few inches under the water. Kids play and adults lounge on it, and bubblers or a chair fit there.

### Pool edge: Vanishing edge

One edge where the water spills over a wall into a hidden catch basin. It makes the water look like it runs into the view, and it needs a slope or a retaining wall, a catch basin and more engineering.

### Pool finish: All tile

A fully tiled interior in small mosaic tile. The most durable and the most striking, and it asks the most from the budget. Warm, humid water grows algae faster, so a smooth, dense finish is easier to keep clean.

### Finish color: White finish, bright light blue water

A white interior. Gives the brightest, lightest blue water.

### Coping: Porcelain

Large-format grey porcelain with a square edge. Crisp and low maintenance, ideal beside a modern house. Check it is rated for exterior use where it freezes. It runs about 32 linear ft around this pool.

### Deck: Porcelain tile

Large-format light grey porcelain tile. A modern, low maintenance deck that resists stains and fading. The deck is about 630 sq ft here. Choose a texture that stays safe when wet, because this deck will be damp often.

### Planting: Modern

Ornamental grasses, gravel strips and square planters. A tidy, low-maintenance frame that suits clean architecture. Choose planting that tolerates storms and keep it a few feet from the water to limit debris.

### Pool fence: Glass

A frameless glass pool fence. It keeps the view open. Your town's barrier code sets the height, the gate and the latch, so ask before you design around it.

### Water features: Sheer descents

Sheer descents: Sheets of water pouring from a wall into the pool. A calm, modern sound that masks street noise. It needs a pump sized for the flow.

### Furniture: Umbrella, Outdoor sofa

Umbrella: A market umbrella. Cheap shade that you can move with the sun. Outdoor sofa: An outdoor sofa and lounge chairs. Makes the deck feel like a living room outside.

### Light: Golden hour

Shown in golden-hour light. Low sun is when the finish, the tile and the planting look their best.

## Why it suits this house

The yard: a roof terrace with planters of silver buttonwood and sabal palms, the Miami skyline and Biscayne Bay behind. A rooftop pool is a structural and access project before it is a design project. A roof has a weight limit, and water is heavy. A structural engineer signs off on the load, the pool is often built as a lightweight shell, and every piece comes up by crane or stairs. That is why rooftop designs stay compact.

The house is a glass-and-concrete high-rise with a private penthouse terrace and floor-to-ceiling sliding doors. A tropical design leans on lush planting, soft curves and water you can hear. Freeform curves, a rock waterfall or sheer descent and layered palms make the yard feel like a resort while still working as a family space.

## Will it fit your yard?

Plan on a clear area of about 34 by 26 ft for the pool, 4 ft of deck around the water and 5 ft to the fence line. The deck as drawn here is about 33 by 25 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 plunge pool hold?** About 2,000 gallons. It is 16 by 8 ft with about 130 sq ft of water, 3.5 ft deep at the steps and 5 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 34 by 26 ft for the pool, 4 ft of deck around the water and 5 ft to the fence line. The deck as drawn here is about 33 by 25 ft.

**What does this design cost?** A planning range for FL is $50,000 to $140,000 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 2 to 4.5 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

On a roof terrace, the glass fence keeps the skyline and the bay in view while still guarding the edge. Porcelain deck and coping stay cooler than dark surfaces in strong sun. At 2,000 gallons the pool weighs far less than a large one, which matters when water sits on a building. The bench and sun shelf give you a place to sit in the shallows.

What to watch: The model leaves out the building and its structural frame. A roof has to carry the water, the shell and the deck, and an engineer decides whether yours can. That may limit the size, the depth or the vanishing edge.

## What this will cost: a planning range

$50,000 to $140,000 for FL, a range from published prices and not a quote.

- The pool: $20,000 to $41,000. 128 sq ft of water at $90 to $250 a square foot (shell, excavation, plumbing, equipment, plaster), held to the small concrete pool price. Steps and the sun shelf are part of the shell.
- All-tile interior: $2,000 to $7,000. 227 sq ft of shell at $8 to $30 a square foot above plaster. Tile is priced $4 to $30 a square foot as a finish, plus the extra labor over plaster.
- Coping: $500 to $1,500. 32 linear ft at $20 to $40 a foot.
- Vanishing edge: $10,000 to $31,000. Pool Research's premium over an average inground pool, and it can run higher.
- Sheer descents: $1,500 to $4,000. Two descents. Each, installed.
- Wall for the water: $2,000 to $8,000. The wall that sheer descents and scuppers pour from, where none exists.
- Pool fence: $11,000 to $24,000. 114 linear ft around the deck as drawn, at $95 to $210 a foot installed.
- Rooftop structure: $5,000 to $20,000. Structural changes to the building ($5,000 to $20,000 or more). The crane lift has no published pool price and is not in this number.

## How long it takes

2 to 4.5 months from contract to first swim. Permits take from a few days to several months, depending on the town, before work starts.

- A vanishing edge needs the catch basin and its wall built to level, so the schedule runs to the long end. One builder source puts an infinity pool at 12 to 20 weeks.
- No source gives a rooftop schedule. The structural review, the crane lift and the building's own rules come before the pool, so ask for a written schedule.

## What it is made of

- Interior: All tile, white (about 230 sq ft of shell). Small glass or porcelain tile over the whole shell. It is the most durable and cleanest looking interior, and the one with the most grout joints to keep tight.
- Coping: Porcelain (about 32 linear ft). Large, flat porcelain slabs with a square edge. Very modern, and the joints and the edge profile need a careful installer.
- Deck: Porcelain tile (about 630 sq ft). Large porcelain tile. Very clean and modern. Check its slip rating for a wet area and keep the joints sealed.
- Pool fence: Glass (about 115 linear ft around the deck as drawn). Frameless glass keeps the view open and needs wiping to stay clear. Its height, gate and hardware have to meet your town's barrier rules.
- Planting: Modern. Ornamental grasses, gravel strips and square planters. Tidy and low water, with the beds kept away from the skimmer.
- Water feature: Sheer descents. Thin sheets of water that pour from a wall. They run on the pool pump and can be loud or quiet, so ask to hear one.

## Keeping it up

- All tile in this climate: Tile is the easiest interior to keep free of algae. The grout is the weak point, so ask how it is sealed.
- When it is resurfaced: An all-tile interior is not replastered. The upkeep is in the grout and the waterline, which should be checked every year.
- Porcelain tile deck: Wash the porcelain with a neutral cleaner and keep the joints sealed. Check the slip rating if it will be wet most days.
- Sheer descents: Sheer descents grow a film of algae on the wall. Wipe it down and run them on a timer rather than all day.
- Glass fence: Glass fence panels show water spots. Wipe them down and rinse the hardware.
- 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?
- Has a structural engineer confirmed this roof can carry a vanishing edge pool with its catch basin, and where does the overflow drain to?
- How is the catch basin sized and hidden, and what happens to the water on a windy day?
- Will a pool this small have room for the equipment, and can I swim in it or only soak?
- How deep is the sun shelf, and can a chair sit on it without tipping?
