Infinity pools do require slightly more maintenance than other pools because you’ll need to constantly monitor the water level. If the water level is out of whack, it won’t correctly flow over the edge, which gives the pool its infinity look. 

That said, the rest of the maintenance is largely dependent on the type of material you choose. Concrete needs a little extra care to prevent algae growth, and you will eventually need to resurface it. Fiberglass and vinyl liners are algae-resistant but they’re not as durable.

It’s fair to be concerned about handling pool lights or wiring in a pool filled with water. But fortunately, pool lights and swimming pools are designed to make it easy and safe to replace the lights without needing to drain the water. Instead, you can turn off the electricity to the pool as a safety precaution, unscrew the pool fixture, pull it up and out to the side of the pool, then change the bulb.

There are some companies that offer acid washes that do not require pool draining. However, the process can take several days and requires a bit more elbow grease to scrub the pool surface compared to draining it entirely. Since your pool surface and age are both a factor, work with a professional to choose the best method.

You’ll need at least 50-by-10 feet for a residential lap pool. Endless pools need as little as 15-by-8 feet. Deciding which type of pool is right for you and your family will depend heavily on the size of your backyard and what can comfortably fit. Don’t forget to leave room for other structures and activities in your yard, such as a swing set, shed, garden, or outdoor grill.
