Pool maintenance costs an average of $230 per service, with prices ranging from $50 to $750 per service, depending on several factors. The type of service will usually be the most significant cost factor, as opening and closing a pool takes a few hours and can total $400 or more, while regular cleanings could cost under $100. The size of your pool and the type of pool—above-ground, in-ground, saltwater—can also affect the price of maintenance.

Installing an infinity pool takes up to 12 weeks. It can take as long as 20 weeks if you have a complex design, are building a pool in an inaccessible area, or face weather-related construction delays. Either way, this is a big job that requires a lot of time and labor to get it right. Pool construction is not a job that should be rushed, as poor installation can lead to expensive recurring repair costs. 

At noon, when the sun is at its highest point, sunlight can naturally increase the temperature of a pool by 0.7 degrees each hour, but this can depend on other external factors. For example, evaporation caused by the sun will cause a pool to lose up to 5 degrees for every 1/2 inch of water evaporated. Using a water heater will produce more reliable results.

The depth of your pool depends on its intended use, the size of your lawn, and whether you opt for an in-ground or aboveground pool. Aboveground pools tend to be between four and six feet deep while in-ground pools range anywhere from three to eight feet. Permanent installations also have the option of shallow and deep ends.
