9 Summer Pool Decor Ideas Using Lights and Floats

Our pool used to look great during the day and completely disappear the moment the sun went down.

We added a string of lights around the deck almost as an experiment one July, not expecting much.

Suddenly people were still out there at ten at night, and the pool looked better lit up than it ever did at noon.

Lights and floats do more to make a pool feel styled than any amount of landscaping around it ever will.

Here are 9 ways to use both to turn a functional pool into a genuine evening destination.

Why lights and floats carry so much of a pool’s overall look

The water itself is the biggest surface in the whole space, and these two elements are what actually interact with it.

• Floating lights and colorful floats give the water surface visual interest it otherwise completely lacks
• Evening lighting extends how long the pool actually gets used each day, not just how it looks
• Both are relatively low-cost compared to permanent hardscaping or landscaping changes around the pool itself

Once the water surface has genuine styling, the whole space reads as considered rather than purely functional.

1. Floating LED Orbs Scattered Across the Water

Simple glowing spheres that transform the pool after dark.

Build it:

• Waterproof, solar-powered LED orbs scattered loosely across the pool’s surface
• A mix of warm white and soft color-changing options, depending on the desired evening mood
• Charged during the day by direct sunlight, requiring no additional wiring or extension cords

Why floating orbs are one of the easiest lighting upgrades available:

• They require zero installation, simply placed in the water at dusk and removed or left floating overnight
• The soft, diffused glow reads as considerably more polished than a single harsh pool light alone
• Solar charging means there’s no ongoing cost or need to remember batteries throughout the season

Cost breakdown: A set of six to eight solar LED orbs runs $25 to $50 depending on size and brightness features.

2. String Lights Draped Around the Pool Deck

Overhead ambiance that frames the whole pool area.

Build it:

• Outdoor-rated string lights run along a fence line, pergola, or deck posts surrounding the pool
• Warm white bulbs rather than cool white, matching the relaxed evening mood most pool gatherings call for
• A timer or smart plug added so the lights turn on automatically at dusk without needing to be flipped manually each evening

Why overhead string lights matter as much as anything floating in the water:

• They light the surrounding deck and seating areas, not just the pool itself, making the whole space usable after dark
• The warm glow reflects off the water’s surface, effectively doubling the lighting’s visual impact
• It’s one of the most affordable upgrades relative to how dramatically it changes the pool area’s evening usability

Cost breakdown: Outdoor string lights run $25 to $45 per 48-foot strand, with most pool areas needing two to three strands.

3. Oversized Statement Floats as Functional Decor

Pool floats chosen specifically for their visual impact, not just comfort.

Build it:

• One or two oversized statement floats, like a large flamingo, swan, or geometric shape, in a bold color
• Left in the pool between uses rather than deflated and stored away, doubling as ongoing decor
• Positioned near the pool’s edge where they’re visible from the main seating area, even when nobody’s using them

Why a statement float works as decor even when it’s not being ridden:

• The bold shape and color add genuine visual interest to the water’s surface throughout the day, not just during active use
• It photographs well for anyone documenting a pool party or casual summer gathering
• Choosing one or two standout pieces avoids the cluttered look of a dozen mismatched inflatable toys scattered everywhere

Cost breakdown: A single oversized statement float runs $30 to $60 depending on size and design.

4. Waterproof Fairy Lights Wrapped Around Poolside Plants

Small twinkling lights layered into greenery near the water’s edge.

Build it:

• Battery-operated or solar waterproof fairy lights wound gently around potted palms, grasses, or other poolside plants
• Positioned close enough to the pool to reflect softly on the water’s surface
• Left on a timer to activate automatically at dusk alongside any other pool lighting already in place

Why fairy lights in the plants add a different texture than string lights overhead:

• The smaller, denser twinkle creates a different visual layer than the broader spacing of standard string lights
• It draws the eye to the landscaping around the pool, not just the water and deck surface itself
• It’s a detail that adds real depth to the evening lighting scheme without needing any additional structure to hang from

Cost breakdown: Waterproof fairy light strands run $10 to $20 each, typically needing two to three for a well-lit planting area.

5. A Floating Drink Tray or Bar Float

Function built directly into the pool’s floating decor.

Build it:

• An inflatable floating tray designed to hold drinks, snacks, or a small ice bucket
• Positioned near the main group of swimmers or floaters rather than drifting to the pool’s edge
• Weighted slightly or tethered loosely to prevent it from floating too far from reach during use

Why a floating bar tray earns its place among purely decorative floats:

• It keeps drinks and snacks within arm’s reach without anyone needing to climb out of the pool repeatedly
• It adds a genuinely hosting-focused detail that elevates a casual pool day into something more like a planned gathering
• The float itself, often brightly colored or patterned, contributes to the water’s overall visual styling even when not actively in use

Cost breakdown: A floating drink tray or bar float runs $15 to $35 depending on size and features.

6. Color-Changing Pool Lights Installed in the Water Feature Itself

A more permanent lighting upgrade built into the pool’s own lighting system.

Build it:

• LED color-changing bulbs installed in place of the pool’s existing standard white underwater lights
• Controlled via a wall switch or smart home app, allowing color and brightness adjustments for different occasions
• Programmed to cycle slowly through a color palette, or set to a single steady tone depending on the event

Why upgrading the pool’s built-in lighting delivers the most dramatic single change:

• It illuminates the water from within, creating a genuinely different atmosphere than any surface-level floating light can achieve alone
• Color options allow the pool to match a party theme or simply shift the mood for a quieter evening swim
• It’s a one-time installation that continues delivering the upgraded look every time the pool lights are used going forward

Cost breakdown: Color-changing LED pool light conversion kits run $150 to $400 depending on the existing fixture type and installation complexity.

7. A Cluster of Smaller Floats Grouped by Color

Multiple inflatable pieces arranged intentionally rather than scattered randomly.

Build it:

• Several smaller floats, like rings or loungers, chosen within a single coordinated color palette
• Grouped together in one section of the pool rather than spread evenly across the entire surface
• Rotated or rearranged occasionally throughout the day to keep the water’s visual layout feeling fresh

Why grouping floats by color reads as more styled than a mismatched collection:

• A coordinated palette across multiple pieces mimics the same curated look found in professionally styled pool photography
• Clustering rather than scattering keeps a clear section of open water available for actual swimming
• It’s an easy upgrade for anyone who already owns several floats, simply requiring more intentional color coordination on future purchases

Cost breakdown: Coordinated color-matched floats run $15 to $30 each, typically $60 to $120 for a full styled cluster of four pieces.

8. Lanterns or Candles Placed Around the Pool’s Perimeter

Ground-level lighting that complements the overhead and floating light sources.

Build it:

• Battery-powered lanterns or enclosed candle holders placed at intervals along the pool’s coping or deck edge
• Warm-toned light sources chosen to match the string lights and floating orbs already in use
• Positioned to avoid direct proximity to pool chemicals or splash zones that could affect battery components

Why ground-level lighting adds a layer overhead lights alone can’t provide:

• It lights the pool’s edge specifically, which matters for both safety and ambiance once the sun goes down
• The lower vantage point creates a different lighting layer than string lights or floating orbs positioned higher or on the water itself
• Battery-powered options avoid the fire risk of open flame directly at a pool’s edge, where splashing is common

Cost breakdown: Battery-powered lanterns run $8 to $18 each, typically needing six to eight for a full pool perimeter.

9. A Floating Light-Up Letter or Number for Special Occasions

A temporary, celebratory addition for parties and milestone gatherings.

Build it:

• Inflatable light-up letters or numbers, like an age or initial, floated in the pool for a specific event
• Battery packs sealed and waterproofed according to the manufacturer’s specific instructions
• Removed after the event, storing easily for reuse at a future celebration

Why a temporary letter float suits special occasions specifically:

• It signals a clear celebratory occasion, distinct from the pool’s everyday styling
• It photographs as a genuine party centerpiece, similar to a birthday banner or balloon arrangement on land
• Storing and reusing the piece means the cost is spread across multiple future celebrations rather than a single use

Cost breakdown: Light-up letter or number floats run $30 to $60 depending on size and lighting features.

Getting started this weekend

You don’t need every idea on this list before the pool starts feeling like a real evening destination.

• Start with string lights around the deck and a set of floating solar orbs in the water
• Add one statement float and a lantern-lit perimeter once the basic lighting feels established
• Save the pool’s built-in light conversion for a dedicated upgrade once you know how much the space actually gets used after dark

My own pool went from a daytime-only feature to the spot everyone lingers at until well past sunset, starting with one strand of string lights.

Budget reality

Pool decor built from lights and floats scales from a small weekend addition to a fuller seasonal setup.

• Under $50: Solar LED orbs, battery lanterns, a single statement float
• $50-120: String lights for the full deck, coordinated float cluster, floating drink tray
• $120-250: Fairy lights layered through poolside plants combined with string lights and floats
• $250+: Color-changing built-in pool light conversion

Most of the transformation comes from lighting layered at different heights around the water, not the total amount spent.

What actually makes the pool feel styled after dark

It was never really about buying the most elaborate floating decor available.

It’s the string lights finally reflecting off the water, the single statement float left in place even when nobody’s using it, the lanterns lining the edge that turn a quick evening swim into something worth lingering over.

Start with lighting at one level, whether overhead or floating, and layer in the rest once you see how much later the pool gets used.
