Setting up a pool on unlevel ground is not recommended as it can damage the pool or yard and put the safety of those using it at risk. If a pool isn't level, the water's weight won't distribute evenly, putting excessive pressure on certain parts. This can cause the pool liner to tear or the walls to collapse, leading to water damage, expensive repairs, or potential injury to swimmers. It is more cost-effective to level the ground correctly before installation rather than waiting to address serious structural issues later.

Generally speaking, most municipalities require you to get a permit when you build a pool. Whether or not you need a permit to install a plunge pool will depend on your local laws. It’s always better to check with your HOA and town clerk before digging for a new pool. Otherwise, violations could result in hefty fines. 

The number of gallons in your pool will determine how much chlorine you’ll need to add to your pool for the first time. Chlorine levels should fall between 1 and 3 ppm. It's crucial to read the instructions on your chlorine packet to determine the number of tablets to put in the water based on your pool's capacity.

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.
