There are a variety of shapes to consider for an outdoor pool. Different shapes are better for certain landscapes or activities. You should choose the shape that best fits your yard and property and lifestyle. A complete turn-key project takes approximately 4-6 weeks. This time frame can change depending on what elements are included with the project (ex: built-in grill, patio, etc.) as well as finishing materials. The scope of the project and number of different trades involved can also impact the length. The cost of an inground pool varies based on the shape but also depends on the finish materials, size, depth, options (basketball hoop, diving board, etc.) and the site topography and access.
