The Kohler Sundae kitchen faucet is a single-handle pull-down faucet with two spray settings, a high-arc spout, a docking system, and an included soap or lotion dispenser. Its main US model number is K-R29475-SD. Check your sink, finish, and replacement-part needs before buying.
In American homes, a kitchen faucet handles more than filling a glass. It helps rinse vegetables, wash pans, clean the sink, and fill tall pots. A faucet that reaches the right spots can make these daily jobs easier. The Kohler Sundae kitchen faucet is designed for this kind of regular use, with a pull-down spray head and a high-arc shape.
The Sundae line includes several bathroom faucets, so the name alone does not identify the kitchen model. The K-R29475-SD family is the key model to check when shopping for the kitchen version. KOHLER lists two spray functions, flexible supply lines, quick-connect fittings, and a soap or lotion dispenser among its features. These are documented product details, not results from hands-on testing.
This guide explains what the faucet offers, how it fits a sink, what to check before installation, and how to deal with common problems. It also covers cleaning, replacement parts, and the questions worth asking before you spend money. Product prices, stock, and available finishes can change by retailer, so confirm those details before ordering.
The Kohler Sundae kitchen faucet is a deck-mounted, single-handle faucet made for a kitchen sink. Its pull-down spray head lets you direct water around the basin instead of relying only on a fixed stream. The tall spout gives room for many everyday tasks, such as filling a stockpot or rinsing a large bowl.
The main US product family is K-R29475-SD. The letters and numbers after the base model can identify a finish or a particular package. For example, K-R29475-SD-CP refers to a polished chrome version, while K-R29475-SD-BL identifies a matte black version. Other finish codes may be offered, so check the current product listing.
The Sundae name also appears on bathroom sink faucets. Those models have different dimensions, flow rates, and parts. Do not use a bathroom faucet manual or a bathroom replacement part just because the collection name matches.

Who May Find This Faucet Useful?
This faucet may suit households that want a pull-down sprayer, a tall spout, and one control for water flow and temperature. The two spray settings also give users a choice between a regular stream and a wider spray for rinsing the sink or dishes.
It may be less suitable when the sink sits beneath a very low cabinet, when the owner needs a particular commercial-style faucet, or when the existing countertop has no practical place for the included dispenser. Measure the space before deciding.
Consider it if
You want a high-arc faucet with a pull-down head and two spray functions.
Check carefully if
You have limited cabinet clearance, a thick countertop, or an unusual sink layout.
Main Features and What They Mean in Daily Use
The useful parts of the Sundae faucet are its spray head, tall spout, single lever, hose, docking system, and included dispenser. Each serves a different purpose. Understanding those roles makes it easier to judge whether the faucet fits your kitchen rather than choosing it by appearance alone.
KOHLER lists a maximum flow rate of 1.5 gallons per minute at 60 psi. This is a stated specification under a defined pressure, not a promise that every home will receive exactly that flow. Actual performance can change with supply pressure, plumbing restrictions, and the condition of the faucet.
Two spray functions
Choose an aerated stream for general filling and a Sweep spray for a broad, angled spray pattern.
High-arc spout
The tall design offers vertical room for pitchers and cookware, provided the cabinet above the sink leaves enough space.
Single-lever control
One handle controls water flow and temperature, so the user does not need separate hot and cold handles.
Pull-down hose
The spray head can move around the basin to rinse different areas.
Docking system
The DockNetik system is designed to hold the spray head in place when it is returned to the spout.
Soap or lotion dispenser
The matching dispenser can reduce countertop clutter, but it requires suitable mounting space and occasional refilling.
Aerated Stream Versus Sweep Spray
The aerated stream is the standard choice for filling a pot, rinsing a cup, or running water into the sink. It is suited to general tasks where a steady flow is useful.
Sweep spray uses angled nozzles to create a broad spray pattern. This can help rinse food residue from dishes or wash the sink basin. It does not remove the need to wipe stuck-on food or clean the sink with a suitable cleaner.
If the spray button stops switching modes, water comes from both patterns at once, or the button becomes loose, the spray head may need attention. Mineral deposits, debris, or worn internal parts can affect switching. Confirm the model and approved replacement head before ordering.
For filling
Use the aerated stream for a controlled, regular flow.
For rinsing
Use Sweep spray when a wider pattern is helpful.
For spray problems
Clean the spray face as directed by KOHLER, then check the model-specific service guidance.
Materials and Finish Choices
KOHLER describes the faucet as having premium metal construction and lists zinc in its technical product information. These terms describe the manufacturer’s stated materials. They do not, by themselves, establish how long a faucet will last in a particular home.
Finish availability can vary by retailer and time. Polished chrome gives a bright, reflective look. Matte black provides a darker surface, while stainless-style finishes can work with many common kitchen appliances. Compare the finish code, not just the color shown in a small online picture.
Water spots, cleaning habits, local water hardness, and contact with harsh products all affect the appearance of a finish. Follow the care directions for the exact finish and avoid abrasive pads or cleaners that could scratch or dull the surface.
Chrome
A reflective finish that can suit both modern and traditional kitchens.
Matte black
A dark finish that pairs well with black cabinet hardware and other dark fixtures.
Other listed finishes
Check the current US product page for the available options and their complete model codes.
Kohler Sundae Kitchen Faucet Dimensions and Sink Fit
Measure the sink, counter, and cabinet space before buying the faucet. The published specification sheet for K-R29475-SD lists an overall height of about 17.5 inches and a spout reach of about 8.44 inches. These dimensions help with planning, but the shape of your sink and the position of the mounting hole still matter.
Spout reach is the distance the water outlet extends over the sink. A reach that is too short may send water close to the back wall of the basin. A reach that is too long may place the water near the front edge. Think about where you usually wash pans and fill containers.
The specification sheet lists installation for one-, two-, three-, or four-hole sinks. The included escutcheon plate can cover extra holes in suitable layouts, but the exact arrangement and included parts should be checked before installation. A compatible hole count does not guarantee that every sink and countertop will fit without adjustments.
Overall height
Approximately 17.5 inches. Measure from the mounting surface to the highest point.
Spout reach
Approximately 8.44 inches from the faucet’s centerline to the outlet.
Maximum flow rate
1.5 gallons per minute at 60 psi, as stated in the product specification.
Mounting
Designed for deck mounting with one- through four-hole sink layouts when the required parts and spacing are suitable.
Check Cabinet Clearance
A high-arc faucet needs enough space to fit beneath the cabinet, shelf, or window above the sink. Measure from the counter to the lowest obstruction, then compare that distance with the faucet’s overall height. Leave room for the handle to move as well.
The spray head must also be easy to pull out and return. A cabinet side, soap bottle, or other object can interfere with the hose or the user’s hand. Consider the space under the sink too, because the hose needs a clear path to move and retract.
Measure vertically
Check the distance from the countertop to the lowest cabinet or shelf.
Check handle movement
Make sure the handle can move through its normal range without hitting a wall.
Check below the sink
Look for bins, pipes, filters, or stored items that may block the pull-down hose.
Plan for the Soap Dispenser
The dispenser needs a suitable opening and enough room below the counter for its bottle or reservoir. If your sink already has a disposal switch, filtered-water tap, or another accessory, count the available holes before you buy.
Do not drill a new hole in stone, glass, or another countertop material unless the work is appropriate for that material and is carried out with the right tools. A countertop installer can confirm whether a new opening is possible. If you cannot use the included dispenser, ask the retailer or KOHLER about the supplied components and possible alternatives.
Count existing holes
Include the faucet, dispenser, disposal switch, and any other deck-mounted fixture.
Check underside space
Make sure the dispenser bottle will not collide with a drawer or stored items.
How to Install the Kohler Sundae Kitchen Faucet
A homeowner with suitable plumbing skills may be able to install this faucet, but the correct instructions for the exact model should guide the work. The flexible supply lines and quick-connect fittings are intended to simplify installation. They do not remove the need to shut off the water, check connections, and test for leaks.
Before starting, clear the cabinet and identify the hot and cold shutoff valves. If a valve is stuck, badly corroded, or does not stop the water, do not force it. Have a plumber address the problem before removing the old faucet.
Keep the installation instructions, mounting hardware, escutcheon, supply lines, and dispenser parts together. Check the contents against the product documentation before you begin. Missing or damaged parts are easier to address before the old faucet has been removed.
Tools and supplies
Gather the tools specified by the installation guide, a bucket, towels, and suitable eye protection.
Water shutoff
Close the hot and cold supply valves and verify that the water stops before disconnecting the old faucet.
Model-specific instructions
Use the instructions supplied for K-R29475-SD rather than relying on a generic faucet video.
Installation Steps
First, close both shutoff valves and open the old faucet to release pressure. Place a bucket beneath the connections. Disconnect the supply lines and remove the old mounting hardware while supporting the faucet from above.
Next, clean the mounting surface and check the hole layout. Place the new faucet and the required escutcheon or gasket as shown in the manufacturer’s guide. Secure the mounting assembly using the specified method. Avoid overtightening, which can damage components or the mounting surface.
Connect the supply lines to the correct hot and cold supplies, then use the supplied quick-connect fittings as directed. Install the dispenser in its suitable opening and fit its reservoir. Keep hoses clear of sharp edges, hot pipes, and objects that may pinch them.
Turn the supply valves on slowly. Check every connection for moisture, operate the handle, and test both spray settings. Run the water as instructed in the manual to flush the lines. Check again beneath the sink after the faucet has been used.
Step 1
Shut off the water, relieve pressure, and remove the old faucet.
Step 2
Clean the deck and fit the faucet and mounting components according to the instructions.
Step 3
Connect the supply lines and dispenser, keeping all hoses free of obstructions.
Step 4
Restore water slowly, test operation, and inspect for leaks.
When to Call a Plumber
Call a licensed plumber if the shutoff valves fail, the supply connections do not match, the countertop is damaged, or the faucet cannot be secured properly. A plumber is also the better choice if water continues leaking from a connection after the installation guide’s checks.
Do not use the faucet if a supply line is split, a fitting is visibly damaged, or water is reaching electrical equipment beneath the sink. Shut off the supply if you can do so safely and correct the fault before using the fixture again.
Stop if a valve fails
Do not remove the old faucet while the water supply cannot be shut off.
Stop if a connection leaks
Find and correct the cause rather than trying to hide the leak with sealant.
Cleaning and Maintaining the Faucet
Regular gentle cleaning helps keep the faucet’s finish and spray face in good shape. Wipe the outside with a soft, damp cloth and dry it with a clean cloth when needed. Use only cleaners approved for the particular finish, and follow the manufacturer’s care directions.
Avoid abrasive powders, scouring pads, and harsh chemicals unless the product instructions explicitly allow them. Strong cleaners can damage some finishes even when they remove mineral marks quickly. Do not mix cleaning products, and keep chemicals away from children.
The MasterClean spray face is designed to help resist mineral buildup. That feature does not mean the spray head can never clog. Hard water can leave deposits over time, and debris from plumbing work may also affect water flow.
Wipe the faucet
Use a soft cloth and a suitable cleaner to remove fingerprints and water marks.
Clean the spray face
Follow the model’s care directions and use a gentle method to clear surface deposits.
Inspect the hose
Look for kinks, wear, leaks, or objects that interfere with movement.
Check the mounting
If the faucet moves at its base, inspect the mounting hardware and follow the service instructions.
How to Deal With Mineral Deposits
If the spray pattern becomes uneven, begin with a visual check for visible deposits. Clean the spray face using the method approved for the model. Do not push sharp metal objects into the nozzles, because they may damage the surface or internal parts.
A retailer’s customer-service response for this model family has stated that the spray head may need replacement rather than separate aerator removal. Do not assume every version uses the same service method. Confirm the exact model and follow its current instructions before removing a component.
If cleaning does not restore the spray pattern, check whether the issue affects both spray settings and whether the water flow from other fixtures has also dropped. Those details can help distinguish a faucet problem from a wider supply issue.
Uneven spray
Check for visible buildup and use the approved cleaning method.
Persistent poor flow
Check the supply and hose before ordering a new spray head.
Uncertain part removal
Use the model-specific parts diagram or contact KOHLER support.
Common Kohler Sundae Kitchen Faucet Problems
A faucet problem does not always mean the whole fixture needs replacing. The symptom, when it occurs, and whether other faucets are affected can help narrow the cause. Start with simple visual checks and use the manufacturer’s service information before taking the faucet apart.
Turn off the water before disconnecting supply lines or removing service parts. If a leak is severe or water is spreading inside the cabinet, close the shutoff valves if it is safe to do so and arrange repairs promptly.
Low water flow
Possible causes include a partly closed shutoff valve, a kinked hose, debris, or a wider supply problem.
Spray modes will not switch
The spray-head buttons or internal diverter may be worn or affected by dirt and mineral deposits.
Spray head will not dock
Check for hose interference, obstruction, or a problem with the docking components.
Leak beneath the sink
Inspect the supply connections, hose connections, and mounting area to identify where water begins.
Dripping from the outlet
A worn valve or another internal issue may be responsible. Confirm the exact source before choosing a repair.
Troubleshooting Low Water Flow
First, check whether the hot side, cold side, or both sides have weak flow. Then see whether other fixtures in the home have the same problem. If several taps have low flow, the cause may be outside the Sundae faucet.
If the problem affects only this faucet, make sure the shutoff valves are fully open and the pull-down hose is not pinched or kinked. Look for obvious damage, but do not pull hard on the hose or force a fitting.
If these checks do not help, consult KOHLER’s low-flow troubleshooting guidance for the exact model. A blockage or damaged internal part may need service. Do not buy a replacement spray head until you know that the spray head is the source of the problem.
Check the pattern
Determine whether low flow affects hot water, cold water, or both.
Check other fixtures
Compare flow at another faucet to see whether the issue may be wider than one fixture.
Inspect visible areas
Look for closed valves, a pinched hose, or visible damage.
Troubleshooting a Spray Head That Will Not Switch
If both spray patterns run at once or the button no longer changes the pattern, debris or wear inside the spray head may be the cause. KOHLER’s support guidance identifies worn spray-head buttons and debris affecting the internal diverter as possible reasons for this symptom.
Clean the spray face using the approved method and test the faucet again. If the buttons remain stuck, the head is damaged, or the spray functions still fail to switch, use the parts diagram to identify the correct replacement.
A replacement spray head must match the faucet model and finish where applicable. Similar-looking heads may use different connections or internal designs. Check the part number with KOHLER or an authorized supplier before ordering.
Start with cleaning
Remove surface buildup with the care method approved for the model.
Confirm the part
Use the exact faucet model to identify the replacement spray head.
Finding and Fixing a Leak
Water beneath the sink can come from a supply connection, the pull-down hose, or another plumbing component. Dry the area and watch carefully to see where fresh moisture first appears. Avoid touching electrical equipment if water is present nearby.
If a connection leaks, follow the installation or service instructions to check it. Do not keep tightening a fitting without knowing its design and required method. Excess force can damage a connection or make the problem worse.
If the leak comes from a damaged hose, cracked component, or inaccessible plumbing joint, stop using the faucet until the issue is repaired. Contact KOHLER support for model-specific parts information or call a plumber if the repair involves the home’s plumbing.
Leak at a supply fitting
Check the connection according to the installation instructions.
Leak from a hose
Identify the correct replacement hose and stop using a damaged hose.
Unknown source
Shut off the supply if safe and get qualified help when needed.
Replacement Parts, Warranty, and Support
The best way to find a compatible replacement part is to start with the complete faucet model number. The K-R29475-SD family includes finish-specific versions, and some components may vary. A photograph can help identify the faucet, but the model number and parts diagram provide a more reliable starting point.
KOHLER offers a service-parts finder and interactive parts diagrams for supported products. Use these tools to identify the spray head, hose, mounting components, or other parts before buying. If the part is difficult to identify, contact KOHLER customer service with the model number and a description of the problem.
The manufacturer lists a Faucet Lifetime Limited Warranty for the product family. Coverage depends on the written warranty terms, the product, the owner, and the circumstances. Do not assume every labor charge, installation error, finish issue, or accidental damage is covered. Check the current warranty document and contact KOHLER before paying for a repair.

Warranty check
Review the current warranty terms and ask KOHLER whether the problem qualifies for assistance.
Proof of purchase
Keep the receipt, installation details, and photographs of any defect when contacting support.
Should You Replace the Spray Head or the Whole Faucet?
A spray head replacement may make sense when the faucet body and handle work properly but the spray pattern or switching function has failed. A hose replacement may be more suitable when the hose itself is damaged or leaking. The exact repair depends on the fault and the parts available for that model.
Replacing the entire faucet may be worth considering if several major components are damaged, compatible parts are unavailable, or the mounting and supply connections also need work. Compare the cost of the confirmed repair with the cost of a new faucet and its installation. Do not replace the full fixture based on a symptom that could have a simple cause.
Replace one part
Consider this when the fault is isolated and the correct part is available.
Replace the faucet
Consider this when the repair is extensive or the overall cost and condition make replacement more practical.
Is the Kohler Sundae Kitchen Faucet Worth Buying?
The Sundae faucet has a practical feature set for a household that wants a pull-down sprayer and a tall spout. The two spray functions, single-handle control, and included dispenser cover several common kitchen needs. Its published dimensions and installation options also make it possible to check fit before purchase.
The main trade-offs are the need for adequate cabinet clearance, space for the dispenser, and model-specific replacement parts. The 1.5-gallon-per-minute rating is useful for comparison, but it does not establish that this faucet will deliver better performance than every competing model. Water pressure and plumbing conditions still matter.
A fair buying decision should also include the full installed cost. Compare the current faucet price, any needed plumbing work, the cost of compatible parts, and the return policy. A lower purchase price may not be the better deal if the faucet does not fit the existing sink or requires extra changes.
Potential benefits
Two spray functions, a high-arc design, a pull-down head, one-handle control, and an included dispenser.
Compare the exact model code, current price, warranty terms, delivery details, and return policy.
What to Compare With Another Faucet
Compare products using the same criteria. Look at spout height and reach, flow rate, spray functions, hose movement, installation layout, included accessories, and finish care. Use official specification sheets rather than product names or photos alone.
If you rarely use a pull-down sprayer, a simpler faucet may meet your needs at a lower total cost. If you often rinse large pans or clean the basin, a movable spray head may be more useful. Your sink size and work habits should guide the decision.
For a compact kitchen
Give extra attention to the faucet height and the clearance above the sink.
For frequent dishwashing
Compare the spray pattern, hose reach, and ease of returning the head to its dock.
For an existing sink
Confirm the mounting-hole arrangement and the space needed for the dispenser.
A Practical Pre-Purchase Checklist
Before you order, take a few minutes to check the measurements and parts that affect fit. This simple step can help prevent a return or an installation delay. Keep the product listing and the official specification sheet available while measuring.
Do not rely only on a finish name or a picture of the faucet. Product images can vary by lighting and screen settings, and retailer listings may use abbreviated model numbers. Match the complete code on the item you intend to purchase.
Measure the mounting area
Record the hole count, spacing, and countertop thickness.
Measure vertical clearance
Check the space from the countertop to any cabinet, shelf, or window obstruction.
Check the dispenser location
Make sure there is a suitable hole and enough room below it.
Confirm the supply connections
Compare the installation requirements with the existing plumbing.
Verify the finish
Check the full model suffix and the actual finish offered by the retailer.
Review service options
Locate the manufacturer’s parts diagrams and warranty information before purchase.
An Easy Way to Make the Final Decision
Write down your measurements and compare them with the official product specifications. If a key measurement is missing or unclear, ask KOHLER or the retailer to confirm it. Do not guess when a small difference could affect installation.
If the dimensions work, the included functions match your needs, and the total cost is acceptable, the Sundae may be a suitable option. If the faucet does not fit the space or its required accessories create a problem, compare another model before committing.
Good fit
The faucet fits the mounting area, clears nearby cabinets, and offers the spray functions you want.
Needs more checking
One or more dimensions, connection details, or included components remain uncertain.
Choose another option
The faucet conflicts with the sink layout or the space available for safe installation.
