Why an 18 Foot Pool Pad is Necessary

From my experience, having an 18 foot pool pad is absolutely essential for setting up a pool safely and securely. It provides a smooth, level surface that protects the pool’s bottom from sharp rocks, sticks, or uneven ground that could cause damage or wear over time. Without this pad, I noticed my pool was more prone to punctures and felt less stable underfoot.

Another reason I found the pool pad necessary is the added comfort it offers. When I’m standing or walking inside the pool, the pad gives a softer, more cushioned feel compared to the bare ground. This makes the swimming experience more enjoyable, especially for kids who spend hours playing in the water.

Lastly, the pad helps extend the life of my pool by reducing friction and abrasion between the pool liner and the ground. It’s a simple step that saves me money and hassle in the long run, making the 18 foot pool pad a must-have in my opinion.

My Buying Guides on ’18 Foot Pool Pad’

When I decided to get an 18 foot pool pad, I realized there were a few important factors I needed to consider to make the best choice. Here’s what I learned from my experience that might help you too.

Why I Needed an 18 Foot Pool Pad

I wanted a pool pad that would protect the bottom of my 18-foot above-ground pool. A good pad prevents punctures, reduces wear and tear, and provides an extra layer of comfort when walking inside the pool. It also helps keep the pool cleaner by minimizing dirt and debris from getting trapped underneath.

Material and Durability

One of the first things I looked at was the material. Pool pads come in various materials like polyethylene foam, polypropylene, or recycled rubber. I chose a polyethylene foam pad because it was thick enough to provide cushioning but also resistant to mold and mildew. Durability was key for me since I wanted the pad to last several seasons without needing replacement.

Thickness and Cushioning

Thickness matters! I found that most 18 foot pool pads range from 1/8 inch to 1/4 inch thick. I went with a 1/4 inch pad because it gave me extra comfort and better protection against sharp objects or uneven ground. If your pool area has rough terrain, a thicker pad is definitely worth considering.

Size and Fit

Since my pool is 18 feet in diameter, I made sure to get a pad that was either exactly 18 feet or slightly larger. A pad that’s too small won’t cover the entire bottom, and one that’s too large can wrinkle and cause issues when setting up. I measured my pool carefully and chose a pad designed specifically for 18-foot pools to ensure a proper fit.

Ease of Installation

I wanted something easy to install without needing special tools. Most pads come in rolls or folded mats. I found that a lightweight foam roll was simple to lay out and adjust before filling the pool with water. Also, I made sure the pad was easy to clean and maintain.

Price and Value

I compared prices online and in stores. While some pads were cheaper, they didn’t offer the thickness or durability I wanted. I decided that investing a bit more upfront was worth it for the long-term protection and comfort my pool pad provided.

Additional Features I Considered

Some pool pads come with UV protection or antimicrobial treatments to resist mold and mildew. Since my pool gets a lot of sun, I chose a pad with UV resistance to ensure it wouldn’t degrade quickly. Also, antimicrobial features gave me peace of mind about cleanliness.

My Final Thoughts

Buying an 18 foot pool pad was easier once I knew what to look for: durable material, proper thickness, exact size, and added features like UV and antimicrobial protection. Taking the time to choose the right pad has extended the life of my pool and made my swimming experience more enjoyable. I hope my buying guide helps you pick the perfect pool pad for your needs!
