Why a Kidney Shaped Pool Cover is Necessary
From my experience owning a kidney shaped pool, I’ve found that having a cover specifically designed for its unique shape is essential. Unlike standard rectangular covers, a kidney shaped pool cover fits snugly around every curve, ensuring no gaps where debris can sneak in. This means my pool stays cleaner for longer, saving me hours of skimming and maintenance.
Another reason I rely on a kidney shaped cover is safety. The custom fit provides better coverage and support, reducing the risk of accidents, especially if you have kids or pets around. It gives me peace of mind knowing that the pool is protected even when I’m not home.
Lastly, a well-fitted kidney shaped pool cover helps retain heat and reduce water evaporation. This keeps my pool warmer and lowers my utility bills. Overall, investing in a kidney shaped pool cover has made pool ownership much easier and more enjoyable for me.
My Buying Guides on Kidney Shaped Pool Cover
When I first decided to get a kidney shaped pool cover, I realized it wasn’t as simple as picking any cover off the shelf. Since kidney shaped pools have that unique curved design, finding the right cover takes some thought. Here’s what I learned through my experience, and I hope it helps you make a smart choice too.
Understanding the Shape and Size
The first thing I did was measure my pool carefully. Kidney shaped pools aren’t standard rectangles or circles, so precise measurements are crucial. I measured the length, width at the widest points, and the curves to ensure the cover fits snugly without gaps. Always double-check these dimensions before ordering.
Material Matters
I found that pool covers come in various materials like vinyl, mesh, and solid plastic. For my kidney shaped pool, I preferred a durable vinyl cover because it’s sturdy and provides excellent protection against debris and UV rays. Mesh covers let water through but keep leaves out, which might be better if you want water drainage. Decide what suits your climate and maintenance preferences.
Types of Covers and Their Benefits
- Safety Covers: Since I have kids around, safety was a priority. Safety covers are strong and can support weight, preventing accidents.
- Winter Covers: These are great for off-season protection. They keep out debris and minimize algae growth.
- Solar Covers: If you want to keep your pool warm, solar covers trap heat from the sun. They’re lightweight and easy to handle.
Custom Fit vs. Universal Covers
I initially considered universal covers, but they often don’t fit kidney shaped pools well due to the curves. I opted for a custom-fit cover tailored to my pool’s exact dimensions. It was a bit more expensive but worth it for the perfect fit and better protection.
Installation and Maintenance Tips
Installing my kidney shaped pool cover was easier with help. Some covers come with installation kits including anchors and straps. Make sure you understand the installation process beforehand. Also, regular cleaning and proper storage during the off-season extend the life of your cover.
Budget Considerations
Pool covers vary widely in price. I set a budget that balanced quality and cost. Remember, investing in a good cover can save you money on pool maintenance and repairs in the long run.
Additional Features to Look For
- UV resistance to prevent material breakdown
- Easy-to-use fastening systems
- Warranty and customer support from the manufacturer
Final Thoughts
Choosing the right kidney shaped pool cover made a big difference in maintaining my pool’s cleanliness and safety. Take your time measuring, consider your specific needs, and don’t hesitate to invest a bit more for a custom fit. That way, you’ll enjoy your pool worry-free for years to come.
