Cost of Inground Rectangular Pool Vs. Curved Pool


Inground pool projects are very extensive and require a much larger budget than their much simpler, aboveground cousins. However, a true inground pool is also much longer lasting and is a more quality landscape project, provided the right materials are used. Shape is one of the most important considerations, and should be decided immediately, although building materials are also very important.

Rectangular Pools

  • Rectangular pools are much simpler than curved pools, because of their straightforward angles. If homeowners wanted to build a concrete pool themselves as an extensive DIY project, a rectangular pool would be the most likely option because of its simplicity. This same simplicity makes it less expensive when hiring a contractor to build the pool for you, or when choosing a premade vinyl or plastic pool insert that is then placed on a foundation in the ground. Costs can vary extensively, depending on the type of pool, and you will probably spend around $15,000 to $60,000. For the rectangular insert itself, $5,500 is an average amount to pay. In a DIY project, money is saved primarily as time spent making the pool.

Curved Pools

  • Curved pools have more challenging angles and tend to be more expensive because of this higher difficulty. It is very difficult to created a curved pool using common building materials, so most homeowners buy inserts or hire professionals. Costs here can vary based not only on the size but also the shape of the pool. Typical costs for a kidney-shaped insert run about $2,000 dollars more than a rectangle version.

Building Materials

  • The building materials used also make a large difference in cost. A pool kit that comes with the necessary plumbing, along with the plastic or fiberglass-based pool insert, is probably the least expensive option, with most of the cost difference lying between the sizes and shapes of the pool. Industrious and experienced homeowners may be able to build a concrete rectangle pool themselves, but for a curved pool, a shotcrete or gunite contractor will probably need to be used, and these specialized skills can easily cost thousands of dollars more.

Patio Materials

  • Patios also affect the cost of an inground pool. A simple one-foot wide layer of tile around the pool can cost hundreds of dollars, and exponentially more as the patio base widens. Many homeowners find that the patio cost is close to that of the pool itself. Patio materials, such as concrete, flagstone or brick will also affect the cost. Fitting tile around a curved pool will take more time and expense than a rectangle pool.

Extra Features

  • Homeowners should also be aware that common extra features can add significantly to the cost of the pool. This includes decking, special lighting, recreation options such as water slides, and any special plumbing features.
