View In PDFAn infinity pool budget needs the pool structure plus the overflow edge, collection basin and return equipment. Price the same pool with and without that feature to establish its extra cost. For the pool itself, Singapore installers advertise concrete pools from about S$50,000 to S$180,000 on their own websites (checked October 2026), but these are advertised starting prices, not quotes, and your plot's ground and access can push the total higher.
Why Infinity Edges Cost What They Cost
An infinity edge lets water spill over a carefully formed edge into a collection arrangement below. The effect depends on the viewing direction and landscape beyond. Establish that sight line on the actual plot before paying for an edge that may be hidden from where you sit or swim.
The designer must coordinate edge levels, overflow collection, water balance and circulation. Some systems use a separate edge pump; others arrange circulation differently. Confirm the actual hydraulic design rather than assuming every infinity pool has the same equipment.
When swimmers enter or water moves across the edge, the collection and balancing arrangement must accommodate that change and return water without starving the circulation equipment. Edge level affects the distribution of the spill: a low section can take more flow than the rest. The feature therefore needs accurate construction and a designed water balance, not just a lowered wall with a pump added afterwards.
How to price the extra work for an infinity edge
Ask for the overflow edge to be priced against the same pool without it. The additional work can include the edge wall, collection basin, balancing capacity, pipework, control equipment and finishes. Edge length and site access affect that scope.
Compare the complete build, including structure, deck, drainage and equipment access. An elevated or constrained site can change much more than the edge detail. A fixed feature surcharge is not a reliable project budget.
EdgeProp’s May 2026 article puts a sunken pool deeper than 1.2 metres at S$150,000 or more as part of a landed home rebuild.
| Budget question | What to price | What to check |
|---|---|---|
| New infinity/overflow pool | Quote for the designed pool, collection basin and return equipment | Confirm structure, GST, ground support and professional fees for your plot |
| Cost of the infinity feature alone | Price the same designed pool with and without the overflow edge | Subtracting prices for differently sized pools does not isolate the edge premium |
| Complete outdoor project | Add only work excluded from the pool quotation | Decking, landscaping, drainage and access works may be separate or partly bundled |
For a new build, establish whether the pool amount includes excavation and disposal, the water-retaining structure, waterproofing and finishes, filtration, overflow collection and balancing equipment, electrical work, testing and commissioning. Identify professional fees, unusual foundations, temporary access and reinstatement separately where excluded. This prevents a plausible pool figure from being mistaken for the complete garden budget.
Plot and Structural Requirements
Infinity edges work best when there's an elevation drop on the far side of the edge: a sloping garden, a retaining wall, or a view that drops away. On a flat plot with neighbours on all sides, the illusion is harder to pull off and the feature becomes more decorative than dramatic. A good builder will tell you honestly whether your plot suits the feature before quoting it.
Settlement or construction-level errors can change how evenly water flows over the edge. The engineer should specify the foundations and structure from the actual site conditions. Piling is a design decision, not an automatic requirement or a guarantee of decades without movement.
Running Costs and Maintenance
Ask the designer to identify each pump and its operating schedule, including any separate edge feature. Estimate consumption from the actual equipment and tariff. The arrangement must still maintain filtration and treatment when a decorative feature is off.
The collection basin and edge need safe maintenance access and cleaning. Do not change pump schedules merely to save electricity without checking how circulation and water treatment work. Agree the operating modes with the designer and service provider.
Calculate the extra pump bill from the actual design
| Input | What to use | Calculation |
|---|---|---|
| Separate edge-pump electrical input | Consumption at your pump’s operating setting | Use electrical input, not the output or horsepower label. |
| Operating time | Your agreed daily schedule and budget period | Multiply electrical input by operating hours. |
| Electricity rate | The tariff you pay | Multiply the calculated energy use by your tariff. |
If your design has a separate edge pump, multiply its electrical input by its daily operating hours, the number of days and your electricity rate.
Use the proposed pump’s actual electrical consumption at its operating setting, rather than treating its output or horsepower label as the bill. The calculation excludes ordinary filtration, water replacement, chemicals, cleaning and repairs. A single monthly maintenance price cannot show the extra cost of the edge unless the collection basin and additional equipment are included.
When the Premium Is Worth It
Where the main terrace and swimming position look towards an open view, an infinity edge can make that view part of the pool’s appearance. Judge the effect from those actual positions before choosing it. Its value is the view and water effect the household wants; there is no assured property-value return that makes the premium worthwhile on every site.
On a flat plot or a pool used mainly for exercise, a simple edge may meet the household's priorities at a lower construction scope. Spend first on the layout, access and finish that affect everyday use. Choose an overflow feature where its view and water effect are worth the extra operating and maintenance responsibilities to you.
How DirectHome Approaches Premium Features
Send DirectHome the available site plan, level information and the view you want to create through the WhatsApp button on this page. These help prepare the site assessment; structural feasibility and overflow design need professional assessment before the fixed-price quote. Do not assume an attractive reference image can be reproduced on every plot.
Ask for the feature as a separate priced scope with its maintenance and operating requirements. That lets you decide whether its visual benefit justifies the additional work on your actual property.
