Kristo Pool is an infinity pool construction company in Delhi building vanishing-edge and perimeter-overflow pools for villas, farmhouses, terraces, and boutique hotels across South Delhi, Chhatarpur, Vasant Kunj, and Delhi NCR. We handle structural assessment, balance-tank engineering, waterproofing, and finishing in-house, with pricing that starts around ₹2,800–₹6,500 per sq. ft. of water surface area depending on edge type, site condition, and finish.
If you’re comparing builders, the rest of this page covers exactly what most quotes leave out: how an infinity edge actually works, what it really costs in Delhi, and whether your terrace or plot can structurally support one.
What Is an Infinity Pool and How Does the Edge Actually Work?
An infinity pool (also called a vanishing-edge or negative-edge pool) is designed so water flows continuously over one or more edges into a collection trough, then gets pumped back into the pool by a balance tank — creating the illusion that the pool merges with the horizon or landscape beyond it.
There are two main edge systems used in Delhi projects:
- Single-sided vanishing edge — one wall of the pool sits lower than the others, and water sheets over it into a narrow catch basin below. Best for pools facing a view, garden, or open terrace edge.
- Perimeter overflow (deck-level) edge — water sits flush with the deck on all sides and drains into a slot channel around the full perimeter. Used more often on rooftop and farmhouse pools where the “floating” effect is wanted from every angle, not just one.
The balance tank has to be sized correctly, or the pool either overflows during heavy bather load or runs dry at the pump. As a working rule, the balance tank volume should be roughly 8–10% of total pool volume for a single-sided edge, and 12–15% for a full perimeter overflow, adjusted for expected occupancy. This detail is almost never disclosed in a written quote — ask any contractor for their balance tank sizing calculation before signing.
Infinity Pool Construction Cost in Delhi (2026 Breakdown)
Most Delhi contractors quote a flat per-square-foot number, which hides where the money actually goes. Here’s the real breakdown for a mid-range residential infinity pool in Delhi:
| Component | Typical Share of Cost | ₹ per sq. ft. (water surface) |
|---|---|---|
| Excavation & RCC shell | 25–30% | ₹450–₹700 |
| Waterproofing (2-coat system + testing) | 8–10% | ₹150–₹250 |
| Balance tank & overflow channel | 10–15% | ₹300–₹550 |
| Filtration, pump & plumbing | 15–18% | ₹350–₹600 |
| Tiling/finish (glass mosaic, natural stone) | 15–20% | ₹400–₹900 |
| Lighting, automation, heating (optional) | 5–12% | ₹150–₹500 |
| Total (mid-range, ground level) | — | ₹2,800–₹4,500 / sq. ft. |
| Total (rooftop/terrace, structural reinforcement included) | — | ₹4,200–₹6,500 / sq. ft. |
For a standard 30 x 15 ft residential infinity pool (450 sq. ft. of water surface), that puts total project cost in the range of ₹13 lakh to ₹29 lakh, depending on edge type, site access, and finish level.
Three cost drivers specific to Delhi that most quotes don’t call out:
- Soil type — much of South and West Delhi sits on compact alluvial soil with variable bearing capacity; a soil test before excavation can add ₹15,000–₹40,000 but prevents shell cracking later.
- Water table depth — parts of North and East Delhi have a high water table, requiring hydrostatic uplift resistance in the shell design, which can add ₹3–8 lakh.
- Municipal/society approval — MCD and RWA structural sign-off for pools above ground floor level (terraces, stilts) typically adds 2–4 weeks to timeline and requires a structural engineer’s report.
If you’re building on a terrace rather than at ground level, the cost and structural requirements are different enough that we’ve covered them separately — see our full guide to [Rooftop Swimming Pool Construction Delhi].
Can You Build an Infinity Pool on a Delhi Terrace or Rooftop?
Yes, but only after a structural engineer confirms the existing slab and columns can carry the additional load — this is not optional and should never be skipped.
Water alone weighs 1,000 kg per cubic meter. A modest 20 x 10 ft rooftop infinity pool at 4.5 ft depth holds roughly 25,500 liters of water — about 25.5 tonnes — before adding the weight of the RCC shell, tiling, and balance tank. Most residential terraces in Delhi are designed for a live load of 150–200 kg/sqm (a general assumption, not a guarantee), which is nowhere near sufficient for a pool without reinforcement.
Before quoting a rooftop project, we run through:
- Structural load assessment of the existing slab, beams, and columns
- Column strengthening or additional support columns where required
- Redesigned waterproofing that also protects the floors below
- A lightweight shell option (FRP or reinforced membrane) where the structure can’t take a full RCC shell
If your project is in Gurugram rather than Delhi proper, the approval process and preferred construction techniques differ slightly by municipal authority — our [Infinity Pool Builder Gurugram] page covers that specifically.
Infinity Pool vs. Conventional Swimming Pool: What’s Actually Different
| Infinity Pool | Conventional Pool | |
|---|---|---|
| Visual effect | Water appears to merge with horizon/landscape | Standard contained water body |
| Extra components | Balance tank, overflow channel/trough | None beyond standard filtration |
| Construction cost | 25–40% higher per sq. ft. | Baseline |
| Structural precision | Very high — edge must be levelled to within 2–3mm | Moderate |
| Best suited for | View-facing plots, terraces, resorts, farmhouses | Any plot, budget-focused builds |
| Maintenance cost | Slightly higher (extra pump load, trough cleaning) | Standard |
How Long Does Infinity Pool Construction Take in Delhi?
A ground-level residential infinity pool typically takes 10–16 weeks from structural approval to handover; a rooftop or terrace project usually takes 14–20 weeks because of the additional structural reinforcement and staged waterproofing testing.
Typical phase breakdown:
- Site visit, soil/structural assessment, and design — 1–2 weeks
- Approvals (structural drawing sign-off, RWA/MCD if applicable) — 2–4 weeks
- Excavation and RCC shell — 3–4 weeks
- Waterproofing and leak testing (minimum 72-hour water test) — 1–2 weeks
- Balance tank, filtration, and plumbing — 2 weeks
- Tiling, finishing, lighting, and commissioning — 2–3 weeks
How Do You Maintain an Infinity Pool?
Infinity pools need everything a conventional pool needs — pH balance (7.2–7.6), chlorine or salt-chlorination dosing, and filter backwashing — plus routine cleaning of the overflow trough, where leaves and debris collect and can clog the balance tank return line if ignored. Expect monthly maintenance costs of roughly ₹4,000–₹9,000 for a mid-size residential infinity pool in Delhi, slightly above a conventional pool of the same size due to the extra trough and balance-tank servicing.
Frequently Asked Questions
Is an infinity pool more expensive to maintain than a normal pool?
Yes, moderately — the overflow trough and balance tank need periodic cleaning and the pump runs more continuously, adding roughly 10–15% to monthly maintenance cost compared to a conventional pool of the same size.
Do I need municipal approval to build an infinity pool in Delhi?
For ground-level pools on an independent plot, approval requirements vary by zone; for terrace, stilt, or rooftop pools, a structural engineer’s report and, in most cases, RWA/builder society and MCD sign-off is required before construction begins.
What is the minimum plot size for an infinity pool?
There’s no strict legal minimum, but practically, a single-sided vanishing edge needs at least 12–15 ft of unobstructed view/drop on the overflow side for the effect to read visually — smaller plots can still use a perimeter overflow design instead.
Can an existing conventional pool be converted into an infinity pool?
In some cases yes, if the structure and one boundary wall can accommodate a lowered edge and an added balance tank, but it usually requires partial demolition of one wall and is often comparably priced to a new build — a site visit is needed to confirm feasibility.
How is an infinity pool different for a hill location like Dharamshala compared to Delhi?
Sloped terrain, monsoon runoff, and seismic zone requirements change the structural and drainage design significantly — we’ve detailed those differences on our Infinity Pool Construction Dharamshala page.
