A pot filler faucet should do more than look beautiful above your stove. It should reach the burners you use, fill your largest cookware comfortably, and fold neatly against the wall when cooking is finished.

MAX Faucets offers pot fillers in several sizes, including 20, 22, 26, and 27 inches. The right choice depends on your stove or cooktop, burner arrangement, mounting location, available wall space, and cooking habits.

This guide explains how the four sizes compare and what to measure before choosing a wall-mounted pot filler for your kitchen.

Quick Answer: What Pot Filler Size Do You Need?

As a general starting point:

• A 20-inch pot filler is a compact option for many residential kitchens.

• A 22-inch pot filler provides a little more coverage while maintaining a balanced residential appearance.

• A 26-inch pot filler offers extended reach for wider ranges, offset mounting locations, and commercial-style kitchens.

• A 27-inch pot filler provides maximum coverage among these four sizes and can suit large cooktops or distinctive traditional designs.

These are general guidelines, not universal installation rules. A product's listed size may refer to its maximum extension, assembled width or another measurement shown by the manufacturer. Always check the exact dimension drawing for the individual model.

Pot Filler Size Comparison

Stove width alone does not determine the correct size. The actual distance from the water connection to the pot-filling position matters more.

What Does Pot Filler Size Mean?

Pot filler dimensions are not always described in exactly the same way. Depending on the product, a size such as 20 or 27 inches may describe maximum reach, overall assembled width or another dimension.

Before purchasing, review:

• The exact product specification drawing

• Maximum horizontal extension

• Spout position when fully extended

• Length and movement of each folding arm

• Folded dimensions

• Distance from the wall connection to the intended filling point

The water outlet should reach over the cookware—not merely reach the edge of the stove.

When to Choose a 20-Inch Pot Filler

A 20-inch pot filler is often a practical choice for a standard residential kitchen. Its compact profile can provide convenient coverage without looking oversized above the range.

Consider a 20-inch model when:

• Your stove or cooktop is a common residential size

• The water connection will be positioned near the centre of the cooking area

• You mainly fill pots on the rear or centre burners

• You want a faucet that folds into a compact resting position

• Cabinets, shelving or the range hood limit wall space

A 20-inch faucet can offer a clean, balanced appearance, but its reach should still be tested against the burners you intend to use.

When to Choose a 22-Inch Pot Filler

A 22-inch pot filler sits between compact residential models and longer commercial-style designs. Those additional inches may help the spout reach farther across a deeper cooktop while maintaining a proportionate look.

Consider a 22-inch model when:

• A 20-inch faucet may not reach your preferred burner comfortably

• Your stove is standard-sized but has a deep cooking surface

• Your rough-in location is slightly offset from the centre

• You want greater flexibility without moving to a much longer model

The difference between 20 and 22 inches may seem small, but placement can make those extra inches useful.

When to Choose a 26-Inch Pot Filler

A 26-inch pot filler offers extended coverage and a more substantial visual profile. It can be a good option for wider ranges, larger cooking surfaces, and professional-inspired kitchens.

Consider a 26-inch model when:

• You have a wide range or commercial-style cooktop

• You want to reach burners farther from the wall connection

• The plumbing outlet cannot be centred perfectly

• You regularly use large stockpots on different burners

• You prefer a longer, modern commercial-style design

Longer reach is helpful only when the faucet has enough room to move without contacting cabinets, shelving, or the range hood.

When to Choose a 27-Inch Pot Filler

A 27-inch pot filler offers the greatest nominal size among these options. Some 27-inch models also have traditional styling, allowing homeowners to combine extended coverage with classic kitchen design.

Consider a 27-inch model when:

• You have a large cooking surface

• You want broad access across several burner positions

• The planned water connection is farther from the primary filling point

• Your kitchen has enough open backsplash space for a longer folding faucet

• The model's design and proportions complement your range and cabinetry

One additional inch does not automatically make a 27-inch model better than a 26-inch model. Arm configuration, spout location, and the way the manufacturer measures the product can all affect usable reach.

How to Measure for the Right Pot Filler

Measuring the actual kitchen layout is more reliable than selecting a faucet based only on stove width.

1. Mark the Proposed Water Connection

Identify where the plumbing outlet will enter the finished wall. If the kitchen is under construction, mark the proposed location on the plan or unfinished wall.

2. Measure to the Burner Centres

Measure horizontally from the proposed wall connection to the centre of the burners where you expect to fill pots. Pay special attention to the front burners because they are usually farthest from the backsplash.

3. Test Your Largest Cookware

Place your largest stockpot on the desired burner and determine where the water stream should land so it can be filled safely and conveniently.

4. Check Vertical Clearance

Allow space for your tallest pot, burner grates, and faucet movement. Make sure the pot filler will not interfere with the range hood, cabinetry, shelves, or decorative backsplash features.

5. Check the Folded Position

Confirm that the faucet can fold into a practical resting position without remaining directly over a hot burner or contacting nearby fixtures.

6. Compare with the Exact Product Drawing

Match your measurements to the specification drawing for the exact model. Ask a qualified plumber or kitchen designer to approve the rough-in location before the wall and backsplash are completed.

Does Stove Width Determine Pot Filler Size?

Stove width is helpful, but it is only one part of the decision. Two kitchens with the same size range may need different pot fillers because of:

• Different burner arrangements and cooktop depths

• Centred or offset plumbing locations

• Different arm and joint designs

• Nearby cabinets, shelves or range hoods

• The size and position of the cookware used most often

There is no single pot filler size automatically correct for every 30, 36 or 48-inch range. Your measurements and the model's specification drawing should determine the final choice.

Should a Pot Filler Reach Every Burner?

Ideally, the faucet should reach the burners where you plan to fill pots. Reaching every burner can be convenient, but it may not be necessary for every household.

Some homeowners use a pot filler primarily for a large stockpot on one rear burner. Others want to fill cookware anywhere on the cooktop. Decide how you will use the faucet, then select the size and mounting location accordingly.

Residential vs. Commercial-Style Pot Fillers

Residential pot fillers often use compact proportions suited to home kitchens, while commercial-style models may provide longer arms and a more substantial appearance for large ranges or busy cooking areas.

However, the word commercial may describe a product's size or design style. It does not automatically confirm that the faucet meets every requirement for a restaurant or regulated commercial installation. Always verify the specifications, certification status of the exact model and applicable local plumbing requirements before purchasing.

Why Dual Shut-Off Valves Matter

Many folding pot fillers include two shut-off handles: one near the wall and another closer to the spout. This allows water flow to be controlled from two locations.

Because a pot filler is usually installed above a stove without a drain below it, both valves should be closed fully after every use. Quality installation, correct sealing, and careful operation are essential.

Common Pot Filler Buying Mistakes

Choosing by Appearance Alone

A finish may coordinate perfectly with your kitchen, but reach, dimensions, and clearance must be confirmed first.

Assuming the Longest Model Is Always Best

A longer pot filler is useful only when the kitchen provides enough room for it to extend, rotate and fold safely.

Assuming the Listed Size Always Means Reach

Manufacturers may describe dimensions differently. Review the drawing instead of relying only on the number in the product title.

Measuring from the Wrong Point

Measure from the actual plumbing connection to the intended filling point over the pot—not simply across the width of the stove.

Finishing the Backsplash Too Early

Changing the water-line position after tile or stone is installed can be difficult and expensive. Choose the faucet and confirm rough-in measurements early in the renovation.

Choosing the Right Finish and Style

After confirming the appropriate size, select a style and finish that complement your kitchen faucet, cabinet hardware, lighting, and appliances.

Popular options include:

• Chrome for a bright, timeless appearance

• Matte black for strong modern contrast

• Brushed gold for a warm luxury look

• Brushed nickel for a soft, versatile finish

• Rose gold and other designer finishes for a distinctive kitchen

Your pot filler does not have to match every metal in the room exactly, but the overall combination should look intentional.

Frequently Asked Questions

Is a 20-inch pot filler enough for a standard stove?

It may be when the water connection is positioned correctly. Measure from the planned connection to your preferred burners and compare those measurements with the exact product drawing.

What is the difference between a 20 and 22-inch pot filler?

A 22-inch model may provide slightly more coverage, but usable reach also depends on arm configuration, joint placement and spout position.

Is a 26-inch pot filler only for commercial kitchens?

No. A 26-inch commercial-style pot filler can also work in a residential kitchen with a wide range, large cooktop or offset mounting position.

Is a 27-inch pot filler always longer than a 26-inch model?

Not necessarily in every usable direction. Product sizes may be measured differently, so compare the exact diagrams and maximum spout positions of both models.

Can a pot filler be installed off-centre?

Yes. An offset installation can work when it improves access to your most frequently used burners. Confirm that the faucet reaches the desired filling positions and folds safely.

Does a pot filler require hot and cold water lines?

Pot fillers are commonly connected to one water supply line. Your plumber should confirm the appropriate connection and local installation requirements.

Should a plumber install the pot filler?

Professional installation is strongly recommended because the faucet requires an in-wall water connection, secure mounting, and correct sealing above an area without a drain.

Final Recommendation

Choose a 20 or 22-inch pot filler when you need a compact or medium-reach solution for many residential kitchen layouts. Consider a 26 or 27-inch pot filler when you have a wider cooking surface, an offset water connection, or want broader coverage across several burners.

The best pot filler is not simply the longest one. It is the model that reaches your cookware, clears surrounding fixtures, folds safely, and complements your kitchen.

Measure first, review the exact product specifications, and have the final installation location approved by a qualified plumber.
