A fiberglass pool can replace a vinyl one for between $50,000 and $65,000. A fiberglass pool will be less expensive over the long-term, as long as it is maintained properly.
You may need to replace both a pool's bottom and its surface in some cases. This will cost you about the same as building an entirely new setup. Depending on your pool size and the material you choose, you might need to spend $35,000 to $65,000.
