How to build a custom gunite pool in East Tennessee
A gunite pool is the one type you can shape to the ground it sits in rather than the other way round — which, on a mountain lot, is the whole point.
Building a custom gunite pool in East Tennessee runs in a fixed order: understand the site (access, slope, rock, drainage), design the pool to those constraints, permit it, then excavate, tie steel, shoot and cure the gunite shell, tile and set the deck, and finally plaster and start it up. Gunite is chosen here because it can be formed to any shape and doubles as structure on a slope, where a pre-formed shell cannot go — and because most of what decides the schedule and the budget is the ground, not the styling.
Why gunite, for a mountain build
Gunite is sprayed concrete over a steel cage, so the shell is formed on site to whatever shape the design calls for — freeform, geometric, a raised spa, a vanishing edge, a tanning ledge. A vinyl-liner or fiberglass pool arrives as a pre-set shape, which is fine on a flat suburban lot and limiting on a mountain one. This is the difference covered in full where we compare the three; the short version is that gunite is the one that bends to the property.
The second reason is structural. On a slope, the pool shell is often doing double duty as retaining structure, holding back the ground on the high side while it holds water on the low side. A monolithic gunite shell, engineered and reinforced, can carry that load. A shell that was moulded in a factory to sit in a level hole cannot, which is why the custom pools you see set into East Tennessee hillsides are almost always gunite.
The site decides the pool
Before a shape is chosen, the ground gets read: how equipment reaches the pool location, how far the site falls across the footprint, what the soil and rock are like, and where water moves. Those four shape the design, the schedule and the budget more than any finish decision — and on a mountain lot they are rarely simple. Access is frequently the tightest constraint, rock is the most common surprise, and a slope means retaining structure and a drainage plan become real lines in the project rather than details.
None of this stops a build. All of it is cheaper to solve on paper than in the hole, which is why the design of a custom gunite pool here starts with the site walk, not the shape.
The build sequence, and where the waiting is
Gunite construction looks chaotic and is actually a fixed order of operations: layout, excavation, plumbing and steel, the gunite shoot, then a cure period that cannot be rushed, then tile and coping, decking, and finally plaster and start-up. Knowing the order makes the quiet stretches far less alarming — the longest of them, the gunite cure, is the shell gaining the strength everything after it depends on, and hurrying it is how a pool cracks in its first winter.
Weather is the main variable once work is visible. Gunite and plaster both need workable conditions, and an East Tennessee wet spring can add weeks no schedule can absorb. A realistic custom build here runs several months from first design to first swim, and about a month of that is design, permitting and scheduling before anything shows on site.
The design decisions that actually matter
Once the site is understood, most design choices are already constrained, which makes them easier. What is left is driven by how the pool will be used: depth profile and step placement for how people get in and move around, a raised spa or spillover if the grade offers one, the edge treatment on the downhill side where there is a view to borrow, and the decking and coping that set how the whole thing feels underfoot.
Finishes — plaster or aggregate interior, tile, coping stone, deck material — are the last layer and the most visible, but they sit on top of decisions already made by the ground. Taken in that order, from site to structure to surface, very little gets revisited.
Permits, the barrier, and who holds the build
A custom gunite pool needs a permit, and a residential pool requires a barrier — fencing with self-closing, self-latching gates and specific rules for doors opening onto the pool area. Requirements are set locally, so the county or city building department and any HOA covenants belong in the plan from the start, not after the deck is poured.
The last decision is who carries the whole build. A design-build company that self-performs excavation, structure and water keeps one party responsible across the connected system a mountain pool actually is; a chain of separate subcontractors leaves the seams — where structure, drainage and shell meet — as the place problems live. That choice matters more here than almost anywhere, and it is worth its own conversation before you sign.
What does a pool actually cost here?

Build yours and see the rangeCommon questions
- How long does it take to build a custom gunite pool in East Tennessee?
- Generally three to five months from the first design conversation to swimming. About a month is design, permitting and scheduling before any work shows on site; after that, the gunite cure and the weather are the main variables. Gunite and plaster both need workable conditions, so a wet spring can add weeks no schedule can absorb.
- Is gunite better than fiberglass or vinyl for a mountain lot?
- For a custom pool on sloped or rocky ground, usually yes. Gunite is formed on site to any shape and can be engineered to double as retaining structure on a slope, where a pre-moulded fiberglass or vinyl shell cannot go. On a flat lot the other types are perfectly good and often faster; the mountain terrain is what tips East Tennessee custom pools toward gunite.
- What is the biggest driver of cost on a gunite pool here?
- Site conditions, not finishes — rock excavation first, then access and retaining structure. All three are hard to see from the surface and all three are settled by the ground rather than the design. A test hole and an honest look at the equipment route resolve most of the uncertainty before contracts. For a planning range on a specific build, the estimator is the fastest honest answer.
