Adding a swimming pool to your outdoor living space is no small feat. First, you must endure days or even weeks of large machinery and mess on your property. Then, there is the cost of an in-ground pool, which is significantly higher than the price of an above-ground model. You may decide that you can afford the actual pool installation, only to realize later that you don't have any cash left over for safety equipment and necessary pool supplies. It is important to weigh all the costs of an in-ground pool to ensure you are ready for what lies ahead.
