if you are thinking of adding a swimming pool to your outdoor space, the cost is one of your concerns. Of course, pool installation costs can vary widely, partly based on whether your pool is sunk into the ground or installed above ground. Expect to pay at least $34000 for an in ground pool, although a more accurate cost will depend on the size, shape and depth of the pool. Other factors include any water heaters or other additions, the surrounding patio area and drainage facilities, and the amount of extra concrete needed for the project. Obtaining at least one quote from a pool company is a must; you should also find out what the company’s policy is if the work takes longer than expected. And being prepared for additional costs, such as putting in retaining walls, moving flower beds or electrical systems during the installation.
