Pot Filler Cost: Existing Plumbing vs. New Water Line
Two pot filler quotes can differ by thousands of dollars while naming the same faucet, because the faucet is not the variable -- the plumbing scope is. One kitchen already has a usable water line behind the stove; the other needs a new line run to the stove wall. Published 2026 figures put the first project near a $1,650 average and the second up to $3,000. This guide works the comparison on plumbing scope alone.

The two scopes, side by side
| Cost line | Existing-plumbing lane | New-line lane |
|---|---|---|
| Project total, published | near $1,650 average | up to $3,000 |
| Plumbing labour | $200-$600 on a capped line | piping labour inside a larger total |
| Piping materials | fittings at the tie-in only | an added $450-$1,800 with labour |
| Wall and backsplash scope | fitting opening only | wall run plus backsplash work |
| Faucet line | same bands in both lanes | same bands in both lanes |
Both lanes sit inside the professional span on the hub guide -- $975 to $3,000, average $1,650, full span $300 to $3,500. The existing-plumbing lane clusters at and below the average; the new-line lane occupies the upper half. An expert quote in trade-press reporting puts a new-plumbing project closer to $3,500, the top of the full span.
The existing-plumbing lane: a tie-in behind the stove
In this lane a water line already reaches the stove wall -- a capped stub from an earlier project, or a line close enough that the plumber's scope is the tie-in and the faucet fitting. Published breakdowns price that labour at $200 to $600, and a total with a mid-range faucet at $350 to $1,100. The wall scope is narrow: the fitting opening and the backsplash around it, rather than a run of wall. This is the lane behind the $300 low end of the published span.
The new-line lane: a water-line run to the stove wall
In this lane no usable line reaches the stove, so the quote carries a run: pipe from the nearest supply point to the faucet position, priced in published breakdowns at an additional $450 to $1,800 for piping labour and materials on top of the fitting scope. The wall scope widens with the run -- wall sections opened along the pipe path and closed again, and backsplash work where the run passes behind the stove, at $55 per square foot in published add-on tables. Plumber time prices at the same $45 to $200 per hour; there is simply more of it. The parts inside this lane are itemised on the faucet and add-ons cost guide.
What moves a quote from one lane to the other
Stated as cost factors only: the distance from the nearest supply line to the stove wall, whether the pipe path crosses finished wall or open framing, and how much backsplash the path touches. A short run through an open remodel wall prices near the bottom of the new-line band; a long run through finished wall, with tile backsplash removed and replaced along it, prices at the top. Neither lane changes the faucet line: the same $150 to $500 basic band and the same designer band over $1,000 appear in both columns of the table above.
Neighbour lanes price different scopes entirely
Neither column here is a kitchen remodel figure -- that hub prices the whole room, cabinets to flooring -- or a range hood figure, which prices ductwork and electrical work above the stove and no plumbing at all. The comparison on this page is narrower: one faucet, two plumbing scopes, and the cost distance between them.

Frequently asked questions
How much cheaper is a pot filler with existing plumbing?
On published 2026 figures, the existing-plumbing project sits near the $1,650 average, with capped-line labour at $200-$600. The new-line project runs up to $3,000 -- the gap between the lanes is the piping and wall scope.
What does running a new water line add?
Published breakdowns price the piping labour and materials for a new line through finished walls at an additional $450-$1,800, before the wider wall and backsplash scope along the run is counted. Backsplash work prices at $55 per square foot for material and labour.
Why do two quotes for the same faucet differ so much?
Because the faucet is the same line in both quotes and the plumbing scope is not. One quote assumes a tie-in behind the stove; the other carries a water-line run, wall work along the pipe path, and the plumber hours both involve at $45-$200 per hour.
Does the new-line lane always cost $3,000?
No. $3,000 is the top of the published professional range, and an expert quote in trade-press reporting puts new-plumbing projects closer to $3,500 at the extreme. Short runs and open walls price lower inside the lane; distance, finished wall, and backsplash scope set the figure.
Is this comparison the same as a remodel plumbing quote?
No. This page compares two scopes for one fixture. A kitchen remodel prices plumbing as one trade inside whole-room scope on its own hub, and a range hood project carries no water line at all -- its ductwork and electrical lines are priced on the range-hood cluster.
