Franklin, TN Pool Builder — Custom Inground Pools by Marlin Exteriors
Marlin Exteriors designs and builds fiberglass, gunite, and vinyl liner inground pools for Franklin homeowners. We handle every phase — from your first site visit through the day you swim.
Why Franklin Homeowners Choose Marlin Exteriors
We are a locally operated pool builder based in Mt. Juliet, bringing more than 20 years of construction experience to homeowners throughout Middle Tennessee, including Franklin and Williamson County.
Every Franklin property is different, and every homeowner has different priorities for how the backyard should look and function. Our job is to help turn those ideas into a pool design that fits the property, your goals, and your budget — while clearly explaining the differences between fiberglass, gunite, and vinyl liner construction.
We hold a BBB A+ rating and back every build with a 1-year workmanship warranty. We handle the entire project — excavation, plumbing, electrical, decking, and finish — so you have one point of contact from groundbreaking to your first swim.

Fiberglass Pools in Franklin, TN
Because the fiberglass shell is manufactured off-site and delivered as a pre-formed structure, installation can generally involve a shorter on-site construction process than a comparable concrete pool. Its smooth, non-porous surface is also one reason many homeowners choose fiberglass for ease of maintenance.
Fiberglass is Marlin Exteriors' specialty. We work with industry-leading shell manufacturers to offer a range of shapes, sizes, and configurations — from sleek geometric designs to resort-style pools with tanning ledges, beach entries, and integrated spas.
Our team evaluates every site individually to confirm the right approach for your specific property.
Available Features
- Tanning ledges and beach entries
- Integrated spillover spas
- Underwater LED lighting
- Saltwater systems
- Custom decking and coping
- Waterfalls and water features
Custom Gunite Pools in Franklin, TN
Because gunite pools are constructed on-site rather than selected from a pre-formed shell catalog, they provide exceptional flexibility when the design calls for a custom shape, depth, layout, or combination of features. Gunite is well-suited to complex shapes, larger estate builds, and projects where design freedom and permanence are the priority.
If you have a specific vision for your backyard — an infinity edge, a grotto, a freeform shape that wraps around existing landscaping, or an integrated outdoor living space — gunite is worth a close look.
Custom Features Available
- Freeform and geometric shapes
- Infinity and vanishing edges
- Natural rock grottos and waterfalls
- Integrated spas and hot tubs
- Tanning ledges and beach entries
- Smart automation and LED lighting
Vinyl Liner Pools in Franklin, TN
Vinyl liner pools are a third new-construction option for Williamson County homeowners. The liner is a custom-fitted membrane available in a wide range of patterns and colors, giving homeowners meaningful design flexibility in the pool's appearance.
During your consultation, we walk through all three pool types — fiberglass, gunite, and vinyl liner — so you can make an informed decision based on your property, goals, and budget.
