How to Hang Outdoor String Lights Over Pool for Stunning Ambiance

There’s something magical about a pool at night—especially when it’s softly lit with warm, glowing string lights. Whether you’re hosting a summer barbecue, enjoying a quiet evening swim, or just lounging with a book, the right lighting transforms your pool area into a dreamy oasis. I remember the first time I hung string lights over my pool. I was nervous—would they be safe near water? Would they look tacky or too dim? But after a few tries and a few lessons learned, I ended up with a setup that felt like something out of a boutique resort. And the best part? You can achieve the same stunning ambiance with a little planning and the right approach.

Hanging outdoor string lights over a pool isn’t just about aesthetics. It’s about safety, functionality, and creating a space where memories are made. But it’s also not as simple as just draping lights from tree to tree. You’ll need to consider the layout of your yard, the type of lights, how they’re installed, and—most importantly—how to keep them safe around water. In this guide, I’ll walk you through every step, from choosing the right lights to installing them securely and beautifully. Whether you’re a DIY enthusiast or hiring a pro, you’ll walk away with practical, real-world advice that’s worked for me and countless others.

Choosing the Right Outdoor String Lights for Your Pool Area

Before you start hammering hooks or drilling holes, you need to pick the right lights. Not all string lights are created equal—especially when water is involved. The last thing you want is a soggy, flickering mess after the first summer storm. So let’s break down what to look for.

Weatherproof and Water-Resistant Ratings (IP Ratings)

First and foremost, look for lights with a high IP (Ingress Protection) rating. This tells you how well the lights resist dust and water. For poolside use, aim for at least IP65. That means they’re dust-tight and protected against low-pressure water jets—perfect for splashes, rain, and humidity. IP67 or IP68? Even better. These can handle temporary submersion (though you should never fully submerge them).

I once bought cheap lights with an IP44 rating. They looked great at first, but after a few weeks of humidity and the occasional pool splash, they started flickering and shorting. Lesson learned: invest in quality. Brands like Brightech, Twinkle Star, and Philips Hue Outdoor offer reliable, well-rated options.

Bulb Type: LEDs vs. Incandescent

LEDs are the clear winner here. They’re energy-efficient, last 10–20 times longer than incandescent bulbs, and run cooler—important near water and kids. Plus, LEDs come in a range of color temperatures. Warm white (2700K–3000K) gives that cozy, inviting glow perfect for poolside relaxation. Want a party vibe? Go for color-changing RGB LEDs with remote controls. Just make sure the controller is weatherproof too.

Pro tip: Look for lights with replaceable bulbs. If one goes out, you don’t have to toss the whole strand.

Length, Spacing, and Power Source

• Length: Measure the area you want to cover—don’t guess. Add 10–15% extra for draping or slack. Most strands are 25–50 feet, but you can connect multiple if your outlet allows.
• Spacing: Standard spacing is 6–12 inches between bulbs. Closer spacing (6″) gives a denser glow; wider (12″) feels more subtle and elegant.
• Power source: Most outdoor lights are plug-in, so plan where your outlet is. Use a weatherproof GFCI outlet (required by code near pools). For longer runs, consider solar-powered options—just note they may dim in cloudy weather.

I used 40-foot warm white LED strands with 8-inch spacing. They gave just the right amount of light—enough to see by, but not so bright it felt like a parking lot.

Planning Your Layout: Designing the Perfect Lightscape

Now that you’ve picked your lights, it’s time to design how they’ll hang. This is where your creativity shines—but don’t skip the planning. A well-thought-out layout ensures even coverage, avoids dark spots, and creates that “wow” factor.

Assess Your Pool and Surroundings

Walk around your pool at night (with a flashlight). Note where the shadows fall. Are there trees, pergolas, fences, or house eaves nearby? These can be natural anchor points. If your yard is open, you might need to install poles or brackets.

I have a rectangular pool with a wooden pergola on one side and a privacy fence on the other. I decided to run the lights from the pergola to the fence in a crisscross pattern—like a web of stars. It looked elegant and provided even light over the entire pool.

Choose a Hanging Style

There are several popular styles, each with pros and cons:

• Straight lines: Simple and modern. Great for pergolas or eaves. Use eye hooks or cable clips every 12–18 inches to prevent sagging.
• Crisscross (X-pattern): Adds depth and drama. Ideal for open pools. Requires at least two anchor points on opposite sides.
• Draped (swag or canopy): Soft, romantic look. Drape lights loosely between trees or poles. Use zip ties or adjustable hooks to control sag.
• Grid pattern: Multiple parallel lines. Best for large areas or when you want maximum coverage.

For a 20×40-foot pool, I used a crisscross pattern with five parallel lines spaced 4 feet apart. It created a balanced glow and looked stunning when viewed from the house.

Use a Mock-Up Before Installation

Before drilling, lay out your plan with temporary markers. Use painter’s tape, string, or even garden stakes with ribbons to simulate where the lights will go. Stand back and look at it from different angles. Does it feel balanced? Are there dark zones over the deep end? Adjust as needed.

I almost made a mistake here—I initially planned to hang lights only along the long sides. But from the patio, the center of the pool looked too dark. Adding the crisscross lines fixed that instantly.

Tools, Hardware, and Safety: What You Need to Install Safely

Now for the fun part: installation. But safety comes first—especially around water. You’re dealing with electricity, heights, and potentially slippery surfaces. Let’s make sure you’re prepared.

Essential Tools and Supplies

• Drill and masonry bits: For concrete, brick, or stone surfaces.
• Stud finder: If attaching to wood (e.g., pergola, deck).
• Measuring tape and level: For precise placement.
• Weatherproof hooks or eye screws: Stainless steel or brass resists rust.
• Zip ties or cable clips: For securing wires and preventing sagging.
• Ladder or step stool: Use a stable, non-slip model.
• Extension cord (if needed): Use a heavy-duty outdoor-rated cord with a GFCI plug. Never use indoor cords.
• Voltage tester: To confirm power is off when working near outlets.

I keep a “pool lighting kit” in my garage with all these tools. It saves time and ensures I never forget something critical.

Electrical Safety Near Water

This is non-negotiable. All outlets near the pool must be GFCI-protected. These cut power instantly if a fault is detected—saving you from shocks. If your existing outlet isn’t GFCI, hire an electrician to upgrade it.

Also, keep all connections (plugs, splitters) at least 5 feet away from the pool edge. Use a weatherproof outlet cover. For longer runs, consider a weatherproof junction box to connect strands safely.

One friend tried to run a cord under the pool deck to hide it. Big mistake. Moisture seeped in, caused a short, and nearly started a fire. Always route cords above ground and use conduit if needed.

Working at Heights: Ladder and Climbing Tips

If you’re hanging lights on a pergola or high fence, use a sturdy ladder with a spotter. Wear non-slip shoes. Never lean over the edge—move the ladder instead. If you’re uncomfortable, hire a professional. A fall near water is especially dangerous.

I once rushed and tried to hang lights on a 10-foot pergola alone. I wobbled, dropped a drill, and nearly pulled the whole ladder down. Now I always ask my partner to hold it—even for quick jobs.

Step-by-Step Installation Guide: From Anchors to Ambiance

You’ve planned, you’ve prepared—now let’s hang those lights! Follow these steps for a secure, beautiful installation.

Step 1: Mark Anchor Points

Use your mock-up as a guide. Mark where each hook or screw will go. For a crisscross pattern, I placed anchors every 4 feet along the pergola and fence. Use a level to keep lines straight.

Step 2: Install Hooks or Brackets

For wood: Pre-drill holes and screw in stainless steel eye hooks. For concrete or brick: Use masonry anchors and screws. For trees: Use tree-friendly straps (not nails or screws), which won’t damage bark. I used 304 stainless steel hooks rated for 50+ lbs—more than enough for the lights.

Tip: Space anchors 12–18 inches apart to prevent sagging. For longer runs, add a center support (like a pole or tension wire).

Step 3: Run the Lights

Start at the power source. Drape the first strand, leaving slack at the ends. Secure with zip ties or clips every 12 inches. For crisscross patterns, weave the strand between anchor points in an “X” shape. Keep tension even—don’t pull too tight.

I connected three 25-foot strands using a weatherproof connector. Test each strand as you go—plug it in to ensure all bulbs work before moving on.

Step 4: Conceal and Secure Wires

Use cable clips to run cords along beams or fences. Avoid draping wires over the pool. If you must cross water, use a non-conductive conduit or run wires high above (e.g., under eaves). Tuck excess cord into a junction box or under decking.

For a clean look, I ran cords through the pergola’s support beams and used black zip ties to blend them in.

Step 5: Test and Adjust

Turn on the lights at night. Look for dark spots, flickering, or sagging. Add more strands or adjust spacing as needed. I had to add a fourth strand over the shallow end—it was too dim for reading.

Pro tip: Use dimmers or smart plugs to control brightness. I use a TP-Link Kasa smart plug—I can turn lights on/off from my phone or set schedules.

Maintenance and Long-Term Care: Keeping the Glow Alive

Your lights will last years—if you care for them properly. A little maintenance goes a long way.

Seasonal Cleaning

Every 3–6 months, wipe bulbs and wires with a dry or slightly damp cloth. Remove leaves, spiderwebs, and debris. For stubborn grime, use a mild soap solution—never harsh chemicals. I do this in spring and fall, after pollen and before winter.

Winter Storage (If Needed)

If you live in a cold climate, consider removing lights in winter. Ice and snow can damage sockets and wires. Coil them loosely and store in a dry, temperature-controlled area. I use a plastic bin with silica gel packets to prevent moisture.

Alternatively, use all-weather lights (rated for -20°F) and leave them up year-round. Just check connections monthly.

Troubleshooting Common Issues

• Flickering lights: Check for loose connections, damaged wires, or water in sockets. Dry thoroughly and reseal with silicone.
• Dim bulbs: Could be a power issue (overloaded circuit) or aging LEDs. Test with a multimeter.
• Sagging strands: Add more support clips or install a tension wire (like a clothesline).

One winter, a branch fell and cut a strand. I replaced it in 20 minutes using a weatherproof connector. No need to redo the whole system.

Upgrade Options for the Future

As tech improves, consider smart upgrades:

• Motion sensors: Lights turn on when you walk outside.
• Color-changing LEDs: Sync with music or holidays.
• Solar-powered strands: Eco-friendly and wire-free (great for remote areas).

I’m eyeing solar-powered fairy lights for the far end of the yard—no outlet needed!
