The average pool size in gallons is 15,360. This number is for a 16’ x 32’ pool with a four-foot depth. However, many pools have different depths at each end or irregular sizes, so you may need to use the formulas above to calculate exactly how many gallons of water you need.

If your pool takes longer than one or two days to fill, you might be dealing with low water pressure. Using a water pressure gauge on your outdoor tap, you can check your water pressure. A reading of 40 psi or below is considered low. A leak, a nearby water shutoff, or several other reasons could cause this. 

If the water pressure isn’t a problem, you could have a low flow rate from clogs, corroded pipes, or other plumbing issues. It’s best to call in a local plumber to get to the root of the issue.

The disadvantages of container pools come down to flexibility and customization. Shipping containers come in standard sizes, so the sizes and shapes are limited. They also have a very distinctive look, which may not suit the aesthetic of your backyard. 

Beyond that, while container pools are more affordable than in-ground pools, certain models can be more expensive. This includes the cost to heat your pool, since the metal walls have more heat transfer than other types of pools (which some brands circumvent with insulation).

The total time to install an inground pool typically ranges from 8 weeks to 4 months. This timeline can be influenced by several factors, including permitting, site preparation, and the construction process itself.

Key phases and their typical durations include:

• Permits: Obtaining necessary permits can take anywhere from two to six weeks.

• Excavation and Site Preparation: This phase takes about a week but can be extended by problematic soil, unexpected ground conditions, or the need to move underground utility lines.

• Construction: The actual build, including plumbing and electrical work, often takes one to two months. The pool material is a major factor here; a concrete pool needs about 30 days to cure, while installing a fiberglass or vinyl liner is much faster.

External factors can also cause significant delays:

• Contractor Availability: Spring and summer are busy seasons, and high demand can lead to long waitlists, potentially adding months to your start date. It is often recommended to start planning and getting estimates up to a year in advance.

• Other Delays: Weather, material shortages, complex designs, and other unforeseen challenges can extend the project timeline.
