Semi-Inground Pools: Cost, Options, and Whether They Suit Texas
Quick Answer
A semi-inground pool is partially sunk into the ground, with the remainder of the wall exposed above grade and usually wrapped in decking or a retaining wall. Installed prices typically run $25,000 to $60,000, between an above-ground and a full inground pool. They suit sloped lots where full excavation is expensive, but in Central Texas expansive clay the exposed wall must be properly engineered and backfilled, because soil pressure acts unevenly on a partially buried shell.
A semi-inground pool sits in between the two categories most people know. Part of the shell is buried, and part of it stands proud of the ground, typically finished with decking, a retaining wall, or a stone surround so it reads as a designed feature rather than a tank in a hole.
It is a legitimate option, and it is also the type most often chosen for the wrong reason. Understanding when it makes sense saves a lot of money.
When a semi-inground pool actually makes sense
Where it does not make sense is on a flat lot, as a way to save money on a full inground pool. The saving is smaller than people expect, because you still excavate, still plumb, still need equipment and decking, and you now also have to build and finish an exposed wall properly. You end up paying nearly inground money for something that is not quite an inground pool. The cases below are the ones that genuinely justify it.
- On a slope. This is the real case. If your yard drops away, a full inground pool means either massive excavation on the high side or a tall retaining structure on the low side. A semi-inground pool works with the grade: buried on the uphill side, exposed and decked on the downhill side.
- Where excavation is expensive or impossible. Central Texas limestone bedrock can make deep digging genuinely costly, and a shallower excavation cuts that line item.
- Where you want a raised edge to sit on. An exposed wall at seat height, capped in stone, is a pleasant thing to perch on and doubles as a design feature.
- As a budget step up from above-ground. It costs more than an above-ground pool but looks dramatically better, and it can be integrated into decking so it does not read as temporary.
What they cost
Installed, semi-inground pools generally run $25,000 to $60,000, which puts them between an above-ground pool (often under $15,000) and a full inground gunite pool ($60,000 to $150,000). Fiberglass and steel-wall semi-inground kits sit at the lower end; a gunite pool built partially above grade with proper stone facing sits at the top.
Watch the finishing costs. An exposed pool wall has to be clad in something, and the decking, retaining, and stonework that make a semi-inground pool look intentional rather than awkward are a real line item. That work is where the apparent savings quietly disappear, and it is the most common reason a semi-inground quote comes in higher than the homeowner expected.
The Central Texas engineering problem
Here is the thing to understand before you commit. A fully buried pool has soil pressure acting on it from all sides, which more or less balances. A partially buried pool has soil pushing hard on the buried section and nothing pushing back on the exposed section, and Central Texas expansive clay pushes with real force as it swells with moisture.
That asymmetry is exactly why a semi-inground pool here needs proper engineering: adequate structural strength in the wall, correct gravel backfill rather than clay, and drainage that keeps water from saturating the soil against the buried side. A gunite shell handles it well because it is engineered on site. A thin steel-wall or kit pool is far less forgiving, and this is where cheap semi-inground installations fail, with bowed walls and cracked surrounds.
The other Texas issue is the exposed wall itself. It sits in direct sun year-round, and it is subject to freeze in winter, so the cladding and the structure behind it need to tolerate both.
The honest recommendation
If your lot slopes, a semi-inground design is often genuinely the smartest solution, and some of the best-looking pools in west Austin are built exactly this way, with a stone-faced exposed wall on the downhill side that turns a grading problem into a feature.
If your lot is flat, get quotes for both a semi-inground pool and a small full inground pool before deciding. Owners are frequently surprised that the gap is narrow, and that for a modest increase they can have a proper inground pool with none of the engineering complications. On a level yard, semi-inground is usually solving a problem you do not have.
Frequently Asked Questions
Typically $25,000 to $60,000 installed, sitting between an above-ground pool and a full inground build. Fiberglass and steel-wall kits are at the lower end, while a gunite pool built partially above grade with proper stone cladding runs toward the top.
The cost people underestimate is the finishing. The exposed section of wall has to be clad and integrated with decking or retaining, and that stonework and hardscape is what makes the pool look deliberate rather than awkward. It is also where the savings versus a full inground pool tend to evaporate, so get the quote for the complete finished result rather than the pool shell alone.
