—Building a new pool
What drives the cost of building a pool
Pools of identical size can end up priced far apart. The difference is in the decisions behind them, and most are yours to make.
The price of a pool reflects the work and materials it needs. Size and depth set the volume of excavation and concrete. Shape affects formwork and finishing time. Access decides whether machinery can be used. Ground conditions found during excavation may add work. Finishes vary widely, from plaster to glass mosaic, and so do coping and deck materials.
Construction guides follow a new pool from the first idea to the first swim, so each stage is easier to plan and to question.
Features add more: infinity edges with their catch basins, spas, water features and extra lighting. Equipment choices — variable-speed pumps, automation, salt chlorination, heating and cooling — add to the installation but may change running costs. Asking for quotes itemised by these elements makes it easier to see where the money goes and where there is room to adjust.
01Summary
What matters most here
Size is only the start
Shape, access and finishes can matter as much as dimensions.
Features add stages
Infinity edges, spas and water features each bring extra work.
Equipment has two costs
What it costs to install and what it costs to run.
02Detail
The main factors
Excavation and access
Machine digging with good access is simpler than hand digging through a narrow gate.
Shell and structure
Depth, shape and ground conditions set the amount of steel and concrete.
Interior and surround
Plaster, tile and glass mosaic differ widely; so do coping and deck materials.
Equipment
Pumps, filtration, chlorination, lighting and automation.
Temperature control
Heating, cooling or a combined heat and cool unit, plus the power supply it needs.
03Before you start
When comparing quotes
Ask for itemised prices
Shell, finishes, equipment and features separately.
Check what is excluded
Approvals, landscaping, electrics and spoil removal are common exclusions.
Compare equipment specifications
Not just the total price.
—In practice
How to use this
List your decisions in order of their effect on cost: size and depth, shape, access, finishes, coping and deck, equipment and features. For each, ask designers to show a simpler and a more elaborate option, which makes the effect of every choice visible. Compare proposals on the same specification, and ask what each assumes about ground conditions, spoil removal and access.
Mistakes worth avoiding
- Comparing totals instead of contents
- Two prices may cover different finishes, equipment and exclusions. Comparing line by line shows what each total actually buys.
- Saving on what cannot be changed later
- Structure, waterproofing and pipework are hard to upgrade once built. Economise on finishes and features, which can be changed later.
04FAQ
Common questions about this
- Is a smaller pool always cheaper?
- Generally, but a small pool with complex features or difficult access can cost more than a larger simple one.
- Do finishes change the price much?
- Yes. Interior finishes, coping and decking vary considerably in material and labour.
- Does a heat and cool unit add a lot?
- It adds equipment, installation and electrical work, and running costs depend on how it is used.
- Why do quotes differ so much?
- They often include different scopes and equipment. An itemised comparison usually explains the gap.
