Quick answer: For the 2BHK flat on this page, two bathrooms, a kitchen and a utility area, the water supply pipe, fittings, valves and in-flat drainage come to ₹17,765 before GST, or ₹20,962.70 with 18% GST, in Ashirvad CPVC and SWR at our prices on 16 November 2026. The building's risers, tanks and pumps are not part of a flat's bill.
This is an illustrative estimate, not a quote. The quantities come from a typical layout we have assumed and set out below, not from anyone's drawings, so a plumber's measured list will differ. What this page shows is the shape of the bill: which lines cost the money and what each item costs today. Labour, sanitaryware, taps, geysers and civil work are not included. For a priced list against your own drawings, use the quote page; it is free.
The flat we priced
- Layout: a 2BHK in an apartment building, two bathrooms (one attached, one common), one kitchen, one utility or wash area.
- Supply: the building brings cold water to a valve at the flat's shaft. From there a 3/4 inch CPVC SDR 11 main runs through the flat, 3/4 inch into each bathroom, and 1/2 inch to every point.
- Points: seven per bathroom (WC, health faucet, basin, two for the wall mixer, geyser in and out), two in the kitchen, two in the utility: 18 in all, each with a brass threaded elbow.
- Drainage: branches from each fixture to the building's soil and waste shafts in Ashirvad SWR Type B; the shafts themselves belong to the building.
- Allowance: 10 percent on every measured run, rounded up to whole lengths.

What changes the number
- A third bathroom adds roughly one bathroom's share of the fittings above, plus a concealed valve.
- Concealed diverters instead of a wall mixer change the bathroom fittings; see the concealed valve guide.
- Sanitaryware and taps are a separate and larger bill; one bathroom's fittings, priced shows a mid-range set.
Questions we get asked
Does the builder not supply this?
In a new flat, usually yes. This list is for owners finishing a bare-shell flat, re-plumbing an older one, or checking a contractor's quote line by line.
Is CPVC needed for the cold lines in a flat?
Not strictly. Cold lines can be uPVC, which is cheaper; see where uPVC saves money. Inside a flat most plumbers use CPVC throughout because hot and cold lines run together.
Can I get this priced for my flat?
Yes. Send the plumber's list or the floor plan through the quote page or on WhatsApp at 99801 00987.
