What seems to be the best choice for in-ground hot tub installation is fiberglass. It is one of the cheapest options on the market. It is arguably as durable as acrylic, too. In this article, we’ll discuss everything you need to know about a fiberglass hot tub. Let’s build you the immense spa of your dreams. Let’s start.
Fiberglass Hot Tub, Defined
A fiberglass hot tub is a type of hot tub or spa made primarily from fiberglass-reinforced plastic. It is a famed alternative to traditional hot tubs. It is to those that are constructed using acrylic, wood, or concrete.
A hot tub consists of many components. The most important part is the shell. It is the container that holds the water of the spa. Other parts are accessories, i.e., blowers, jets, pumps, and filters.
Fiberglass Hot Tub Shell
A fiberglass hot tub shell is the main structure or body of a hot tub made from fiberglass material. The shell holds the water. It provides a seating and bathing area.
Fiberglass is famous for hot tub shells. It is due to its durability and strength. It can also withstand chemicals. Moreover, temperature changes.
Fiberglass shells are constructed by layering fiberglass strands. They are reinforced with resin to craft a solid and rigid structure. The combination allows for a smooth and non-porous surface. As a result, they are resistant to stain and algae growth.

6. Ease of use
A fiberglass pool with a spa may seem difficult to maintain. But, the opposite is true. It is easier to care for than having a spa not attached to your pool. Your pool filter is continually working to collect debris and steer clear of algae. Thus, having your pool and hot tub connected can also keep your spa cleaner.
Sanitation can also be simultaneous. Your hot tub is attached; it is the way it makes maintenance simpler.
7. Backyard aesthetics and saves space
It is no doubt that it is always impressive to see a pool and a spa together. Whether it’s built-in or attached from a separate mold during installation, pool enthusiasts are always happy. Happy when they decide to add a spa to their outdoor space.

8. Fade together over time.
All inground pools will fade as time passes. The good thing with a fiberglass hot tub is that the fading will be even. It will grow to be gradual and seamless in both pool and spa. It is because it is constructed simultaneously using the same batch of materials.
Pros and Cons of a Fiberglass Hot Tub: Cons
1. Smaller swim area
One drawback of a fiberglass spa is that it will cut into your swim space. It will limit typically on your pool’s shallow end. Remember, fiberglass pools generally are no larger than 40 feet long and 16 feet wide. A built-in spa would take away an estimated 10 x 10 foot area.
2. No mixing colors
Most people will match their spa’s gel coat color to their fiberglass pool. Thus, if you want to get crazy and do a blue pool with a pink spa, you wouldn’t be able to do this. They must be constructed separately if you want to mix up your fiberglass pool and hot tub.
3. Difficult to move
Fiberglass hot tubs are typically installed as permanent fixtures. It can be challenging to move once they are in place. If you expect the need to move your hot tub in the future, it is not your suitable option.

Finally, your inground hot tub can be used to create stunning water features. You can opt to add a cascade waterfall from the spa to the pool.
