Why Pool Covers 18 Ft Are Necessary

From my experience, having an 18 ft pool cover is a game changer for maintaining a clean and safe pool. I’ve found that this size perfectly fits my pool, providing complete coverage that keeps out leaves, dirt, and debris. It saves me so much time and effort on cleaning, especially during the fall when everything seems to be falling into the water.

Another reason I appreciate my 18 ft pool cover is the safety aspect. It acts as a barrier that prevents kids or pets from accidentally falling in, giving me peace of mind when I’m not around. Plus, it helps retain heat and reduce water evaporation, which means my pool stays warmer longer and I don’t have to refill it as often. Overall, my 18 ft pool cover is a smart investment that protects both my pool and my family.

My Buying Guides on Pool Covers 18 Ft

When I decided to get a pool cover for my 18-foot pool, I quickly realized there are several factors to consider to make the best choice. Here’s what I learned through my research and experience, which I hope will help you find the perfect pool cover for your needs.

1. Know Your Pool Size and Shape

First, I measured my pool carefully to confirm it was exactly 18 feet in diameter. Pool covers come in different shapes—round, rectangular, and oval—so matching the cover to your pool’s shape is crucial for a snug fit. If your pool is 18 feet round, look specifically for covers labeled as 18 ft round to avoid gaps.

2. Choose the Right Type of Pool Cover

There are several types of pool covers, and I had to decide which suited me best:

  • Winter Covers: Heavy-duty covers that protect your pool during off-season months by blocking debris and preventing algae growth.
  • Solar Covers: Lightweight covers that help retain heat and reduce water evaporation while keeping debris out.
  • Safety Covers: Stronger covers made with mesh or solid material designed to support weight and prevent accidental falls.

I considered how long I’d leave the cover on and my primary purpose—whether it was for safety, heat retention, or debris protection.

3. Material Matters

The durability and effectiveness of the cover depend largely on the material. I found that:

  • Polyethylene and vinyl covers are durable and good for winter protection.
  • Mesh covers allow water to drain through but keep leaves and debris out, which is great if you live in a rainy area.
  • Bubble solar covers help trap heat but can be less durable if not handled carefully.

I picked a material that balanced durability with my local climate conditions.

4. Ease of Installation and Removal

Handling an 18 ft pool cover can be tricky, so I looked for covers that came with easy-to-use straps, reels, or automatic rollers. This made my life easier when putting the cover on or taking it off, especially since I’m managing it mostly by myself.

5. Check for UV and Weather Resistance

Since the cover would be exposed to sun, rain, and wind, I made sure it had UV protection and was resistant to harsh weather to extend its lifespan. This also helped maintain the cover’s color and strength over time.

6. Consider Your Budget

Prices for 18 ft pool covers can vary widely depending on material and features. I set a budget but also balanced cost against quality because I wanted a cover that would last multiple seasons without frequent replacement.

7. Read Customer Reviews

Before making my final decision, I read reviews from other pool owners with 18 ft pools. This gave me insight into real-world performance, durability, and ease of use that product descriptions didn’t always cover.

8. Additional Features to Look For

Some covers come with extras like:

  • Anchor kits for safety covers
  • Repair patches
  • Warranty coverage

These features gave me added peace of mind.

Final Thoughts

Buying a pool cover for an 18 ft pool isn’t just about size—it’s about choosing the right type, material, and features that fit your lifestyle and environment. Taking the time to evaluate these factors helped me protect my pool effectively and enjoy it more throughout the year. I hope my guide helps you make a confident choice!
