It's time for a little honest talk about fiberglass pools. I am about to give you the straight truth about fiberglass pools and it may blow your mind coming from a guy that builds and sells fiberglass pools for a living.

First and foremost, fiberglass pools are not for everyone! You’re probably thinking why would a fiberglass pool builder tell anyone that fiberglass pools aren’t for everybody? Well, because it’s the truth. I don’t sugar coat anything about the pool industry. There are definite drawbacks to fiberglass pools, but there are many more reasons why they can suit anybody. Let's get the disadvantages out of the way so we can focus on why you should have a fiberglass pool.


1: SIZES. The biggest drawback of fiberglass pools is that we are limited by the DOT to pools that are only 16’ wide. This can be a significant drawback if you are looking for a large and wide pool.

2: CUSTOM DESIGNS: Fiberglass pools are limited to the models and the molds the manufacturer has. These molds can be customized slightly but generally speaking, what you see is what you get with a fiberglass pool
