How It's Calculated
How This Estimate Is Calculated
This tool starts from the same real range we quote from every day: whole-home Poly B replacement typically runs $8,000 to $18,000, with most homes landing between $10,000 and $13,000. Your home's size sets the starting band within that range.
The Factors
What Each Answer Changes, Honestly
Bathrooms are the one factor with an exact published figure behind it: roughly $800 to $1,500 added per bathroom beyond a typical two, since each additional bathroom means more fixtures and more pipe runs to complete. Home size sets the base band, since larger homes need more pipe and more labour, full stop.
Storeys and basement type don't get an invented dollar figure here — instead, selecting more than one storey or a finished basement nudges the displayed range toward its higher end, since multi-level homes need more complex routing and finished basements add a drywall-restoration step an unfinished space skips. See our Poly B replacement cost breakdown for the full editorial explanation of these same cost drivers in more depth.
The Honest Limit
Why the Real Number Still Requires an Assessment
A calculator with four inputs can't see your actual plumbing, your actual access, or your actual fixtures.
Access, layout and existing plumbing routing all affect the real number in ways four questions can't fully capture.
We'd rather give you an honest planning range than a precise-looking number with no basis behind it.
A referral to a licensed contractor turns this planning range into a firm, fixed price — at no cost to get there.
Common Questions
Frequently Asked Questions
Is this an exact quote for my home?
No. This calculator gives you a planning range based on the factors you select, so you can budget realistically. Your firm, fixed price comes only from a referral to a licensed contractor, where the contractor looks at your actual home.
Why does it give a range instead of one number?
Because an honest estimate without seeing your home is a range, not a single number. We would rather give you a realistic planning range than a made-up precise figure that has no basis until a plumber has actually looked at your plumbing.
Does the estimate include drywall restoration?
Yes. The range already reflects a whole-home repipe with drywall restoration included, matching how we actually quote every job -- pipe and walls together, one price.
Why do more bathrooms increase the estimate?
Every additional bathroom beyond a typical two means more fixtures, more pipe runs and more access points to open and close, which is real added labour and material -- not an arbitrary markup.
What happens after I get my estimate?
The estimate is a starting point for your own planning. When you are ready for a real number, a referral to a licensed contractor gives you a firm, fixed quote based on your actual home, not an estimate.
Is this a repiping cost calculator or a quote?
It is a repiping cost calculator - it turns your home's own details into a realistic range. A quote is a different document, and it comes from a licensed contractor who has actually seen the house.
In Short
Poly B Replacement Cost Calculator — The Short Version
This poly b replacement cost calculator turns your home's size, bathroom count, storeys and basement type into an instant planning range, grounded in the real $8,000 to $18,000 whole-home envelope and the $800 to $1,500 per-bathroom figure -- never a single fabricated number, never outside that range. It's a starting point for your own budgeting, not a quote; the firm, fixed price for your actual home still comes from a on-site Poly B assessment, with the pipe and the drywall restoration priced together.
