Planning
Gunite or fiberglass
These are not a good option and a cheap one. They are two different builds with different constraints, and for most yards one of them is clearly the right answer once you know what you are optimising for.
We build gunite. That is worth saying at the top so you can weigh the rest of this page knowing it, and so you can tell that the fiberglass case below is being made properly rather than set up to lose.
Gunite, in one paragraph
A steel cage is tied in the excavated hole and concrete is sprayed onto it, then shaped by hand and finished. The pool is formed in your yard, so the shape, depth profile, benches, shelves, and the spa are drawn rather than selected. It takes longer, it costs more, and there is effectively no limit on geometry.
Fiberglass, in one paragraph
A finished shell is manufactured elsewhere, delivered, and set into a prepared hole. Install is fast, the surface is smooth and easy to keep, and the shape is whatever the manufacturer makes. The shell has to physically reach the backyard, which is where most fiberglass plans in this area end.
The question that settles it fastest
Can a truck carrying a shell wider than your side gate reach the back of the property, or can a crane reach over the house. On a lot of established lots the answer is no, and that decides the build before anyone discusses finish. It is worth checking first because it is free to check.
Where fiberglass genuinely wins
A straightforward rectangular or kidney pool, a yard with clear access, and an owner who wants water this season rather than a shape nobody else has. Shorter build, less disruption, less finish maintenance over the years. If that describes you, that is the right pool and you should not be talked out of it.
Where gunite is the only real answer
Tight or sloped lots, anything that has to follow an irregular boundary, raised bond beams and spillover spas, tanning shelves, and any depth profile that is not on a catalogue page. Also anyone who wants the finish and coping to sit inside a wider hardscape design rather than next to it.
The long view
Fiberglass front loads its advantage: quick, clean, low maintenance early on. Gunite front loads its cost and pays it back in fit and in resurfacing rather than replacement down the line. If you intend to keep the house, that trade usually favours gunite. If you intend to move in a few years, it usually does not.
How to decide in one afternoon
- 01
Measure the gate
Post to post, at the narrowest point, including anything fixed that cannot move. This one number rules out more fiberglass plans than any other.
- 02
Say what the pool is for
Swimming lengths, cooling off, kids, or entertaining. Each wants a different depth profile, and only one of them needs a custom shape.
- 03
Walk the boundary
If the usable area is not a clean rectangle, a formed pool will fit it and a moulded shell will fight it.
- 04
Pick a horizon
How long you plan to be in the house changes which of the two is the better financial answer, honestly in both directions.
Questions
Frequently asked
Which one should I choose?
Gunite if the shape matters, if the yard is awkward, or if you want depth and features decided by you. Fiberglass if a stock shape fits your space and you want the shortest build. Neither is the better pool in the abstract.
Is one easier to maintain?
A fiberglass surface is smoother and holds less algae, so it asks slightly less brushing. Gunite interiors are refinished on a cycle rather than never. Water chemistry is the bigger factor for both.
Can a fiberglass shell fit through my gate?
That is the question that decides it. The shell arrives in one piece and needs a clear path and usually a crane. If the only access is a narrow side yard, gunite may be the only option that works.
