A pot filler looks like the simplest fixture in the kitchen: one arm, one valve, one job. It is also the fixture Canadian renovators most often get wrong on fit, because everything depends on measurements taken before the wall closes up. The reach of the arm, the height above the burners, the spot where the supply line comes through the tile: all of it has to line up with your range and your rough-in. This guide covers the standard size ranges, how to measure, and the clearances that separate a pot filler you use daily from one that just decorates the wall.
The four dimensions that decide whether it fits
Spec sheets publish plenty of numbers, but four of them do almost all the work.
| Dimension | What it tells you | Typical range |
|---|---|---|
| Extended reach | How far the arm stretches from the wall to the outlet when fully unfolded | Roughly 20 to 26 inches (about 50 to 66 centimetres) on most double-jointed models |
| Folded projection | How far the fixture sticks out from the wall when the arm is folded flat | Often 2 to 4 inches (5 to 10 centimetres) |
| Spout drop | The vertical distance from the supply connection down to where water actually exits | Varies widely by design, so check the line drawing |
| Supply connection | The size and type of fitting your plumber roughs in behind the wall | Commonly a half-inch female threaded connection, cold water only on most models |
Extended reach is the headline number. Folded projection is the forgotten one, and it matters just as much: a pot filler lives folded against the backsplash most of its life, and a bulky fold can crowd a shallow range hood, a pot rail or a window casing.
How to measure your space before you shop
- Measure from the finished wall to the centre of your front burners. This is the distance the arm must cover. Measure from the tile surface, not the stud, and to the burner centreline rather than the front edge of the range. Compare it directly to the extended reach on the spec sheet.
- Measure your tallest stockpot with its lid on. The outlet needs to clear it while the pot sits on a burner. If you do late-summer canning, measure the canner, not the pasta pot.
- Map the backsplash zone. Note the backsplash height, the bottom edge of the range hood, and anything mounted on the wall. The folded fixture has to live in that zone without collisions.
- Locate the rough-in, or plan it. In a full renovation your plumber sets the supply stub wherever you decide. In a retrofit, the existing stub dictates mounting height, and you shop for a fixture whose drop and reach work from that fixed point.
Clearance rules, stated generally
There is no single code-mandated mounting height for a pot filler in Canada. The National Plumbing Code sets general supply requirements, provinces adopt it with amendments, and your local inspector and licensed plumber have the final word whether you are in Vancouver, Regina or Halifax. What follows are the practical clearances the trade works to, not code clauses.
- Height: high enough that the outlet clears your tallest pot with room to spare, but not so high that falling water splashes. Many installers centre the fixture between one and two feet above the cooking surface, then fine-tune to the household's cookware.
- Reach: the extended outlet should land over the burners you actually fill pots on. Reaching the back burner only is a common compromise that gets old quickly.
- The hood: confirm the folded fixture clears the lower edge of the range hood and its controls, especially low-profile and under-cabinet hoods.
- Heat: follow the manufacturer's guidance on distance from burners, especially high-output gas ranges. Finishes and seals are not meant to live in a heat plume.
Wall-mount, deck-mount and the island question
The classic pot filler is wall-mounted behind the range, where the standard reach ranges above apply. Deck-mounted versions exist for islands and for ranges without a usable wall behind them. A deck-mount fixture spends part of its reach just crossing the countertop, so compare the extended reach against the full distance from the mounting hole to the far burner centreline. Deck-mount also means a hole in the counter and a supply line through the cabinet, decisions best made before the stone is cut.
A cold-climate note for Canadian kitchens
If your range sits on an exterior wall, as it does in plenty of Prairie and Quebec homes, talk to your plumber about the supply routing. Water lines in exterior walls are a known freeze risk in a Canadian winter. Good practice keeps the piping on the warm side of the insulation, a routing question rather than a reason to skip the fixture. Also look for cUPC or CSA marks on the spec sheet, showing the fixture is listed under Canadian plumbing standards. Reputable brands sold in Canada, including Riobel, Brizo, Aquabrass and ROHL, publish this listing information openly.
Common fit mistakes
- Buying the fixture after the rough-in is set. If the stub is at the wrong height for the model you want, you are opening tile. Choose the fixture first.
- Sizing reach to the back burner only. Measure to the front burner centreline and buy reach accordingly.
- Ignoring folded projection. The arm folded flat still projects from the wall. Check it against your hood, shelf and window trim.
- Sizing to your current range. If a deeper professional-style range is in your five-year plan, measure for it now. Ranges change, tile does not want to.
- Forgetting the drip. There is no drain below a pot filler, and the arm holds a little residual water after use. Normal, but a reason to mount over the cooktop, not a counter edge.
Reading the spec sheet like a pro
Every serious manufacturer publishes a dimensioned line drawing. Find the extended reach, the folded projection and the vertical drop on that drawing rather than trusting a marketing bullet. Confirm the connection size and that the model uses dual shutoff valves, one at the wall joint and one at the outlet, the standard belt-and-suspenders design on quality pot fillers. Finally, check the finish name against your main faucet, since the two share a sightline. It helps to shop the pot filler alongside our kitchen faucets collection so the pairing is deliberate rather than close-enough. For the wider planning picture, our buying guides hub covers the rest of the kitchen, and everything we stock ships across Canada.
Frequently asked questions
What is the standard height for a pot filler?
There is no universal standard. The working rule is to clear your tallest pot with its lid on, while keeping the outlet low enough to limit splashing. Many installations land between one and two feet above the cooking surface, but your cookware and rough-in location should drive the final number.
How much reach do I actually need?
Measure from the finished wall to the centreline of your front burners and choose a model whose extended reach meets or exceeds that figure. Most double-jointed pot fillers fall roughly between 20 and 26 inches of reach, which suits most standard and pro-style ranges when the fixture is centred behind the cooktop.
Can I install a pot filler on an exterior wall in Canada?
Often yes, with proper detailing. The supply piping should stay on the warm side of the wall insulation, and requirements vary by province and municipality, so confirm the plan with a licensed plumber before the wall closes.
Do pot fillers use hot or cold water?
Most are plumbed to cold water only, since the pot goes onto a burner anyway and a single supply keeps the installation simple. Some models can be plumbed either way, so check the spec sheet and confirm with your plumber rather than assuming.
