Pricing a pool has to take a few things into account. Access to the pool site can alter a price, with difficult access other machinery may be needed. The type of pool will also be a factor in the cost. A Gunite pool will typically run more costly than a similar sized lined pool. Potentially higher costs can occur under certain circumstances or should you desire any add ons, ie patio, shed, fire-pit. Potentially higher prices can occur for the largest of pools and for different areas with differing building and disposal codes.
