The kohler simplice kitchen faucet is a single-handle design that many homeowners choose for its clean lines and straightforward operation. In this guide you will learn what the Simplice line offers, how to confirm it will fit your sink, how to install it step by step, and how to troubleshoot the problems owners most often run into. Whether you are shopping or already own one, you will leave with practical steps you can use right away.
What the Kohler Simplice Kitchen Faucet Offers
Kohler’s Simplice family is built around a simple, uncluttered profile. Most versions use a single lever that controls both water temperature and flow, which makes them easy to operate with a wet hand or an elbow. The spout is typically a fixed or swivel design, and some configurations include a pull-down or pull-out spray head. Because the product range changes over time, always check the exact model number on the box or spec sheet rather than relying on a general description.

Owners often describe the single-lever action as smooth and predictable, and the lever travel is usually short enough that you can find the temperature setting quickly. If you are comparing styles, our overview of Single-Handle Kitchen Faucets: Control, Cartridges, Care explains why this layout has become so common in home kitchens.
Checking Fit Before You Buy a Kohler Simplice Kitchen Faucet
Fit problems cause more returns than almost anything else with faucets, so measure before you order. Start with the number of holes in your sink or countertop. A single-hole faucet needs only one opening, while three-hole installations use a separate spray hole and two handle holes. Manufacturers specify the hole diameter and the minimum deck thickness the faucet is designed for, and you should compare those figures against your countertop.
Next, measure the clearance under the sink. The mounting nut, supply lines and any filter hardware need room, and cabinet doors can be blocked by a deep base. Our guide to Measuring for a New Kitchen Faucet: Holes, Clearance, Fit walks through these checks in more detail.
Quick Fit Checklist
- Count the existing mounting holes and note their diameter.
- Measure countertop or sink deck thickness.
- Confirm the faucet’s listed hole requirement matches your sink.
- Check cabinet depth and clearance for the mounting nut and tools.
- Note your supply line type (braided stainless is common) and water shutoff valves.
- Decide whether you want a spray head, and whether it needs a separate hole.
How to Install a Kohler Simplice Kitchen Faucet, Step by Step
Installation is manageable for a confident DIYer, but plan for about one to two hours, longer if corroded fittings need to be cut or replaced. Work with the water supply shut off and the sink empty.
Step 1: Gather Tools and Shut Off the Water
Turn off the hot and cold shutoff valves under the sink, then open the faucet to relieve pressure. Keep a towel in the cabinet to catch residual water.
Step 2: Remove the Old Faucet
Disconnect the supply lines, loosen the mounting nuts beneath the sink with a basin wrench, and lift the old faucet out. Clean any old putty or gasket residue from the sink surface so the new gasket seals evenly.
Step 3: Prepare the New Faucet
Lay out all components and compare them against the manufacturer’s diagram. Insert the gasket or sealing base as directed, and thread any hoses through the holes in the correct order before setting the faucet in place.
Step 4: Mount and Tighten
Set the faucet through the sink holes, then work up from below to install the washers and mounting nuts. Tighten evenly so the faucet sits level and does not rock. Avoid overtightening, which can crack the deck or distort the base.
Step 5: Connect Supply Lines and Test
Attach the hot and cold supply lines to the matching shutoff valves, then slowly open the valves. Run the faucet for at least a minute on each setting, and check every joint for drips. Tighten fittings a quarter turn at a time if you see moisture.
Tools and Materials Needed
- Basin wrench
- Adjustable wrench
- Plumber’s tape or thread sealant (only where the manufacturer allows)
- Bucket and towels
- Flashlight
- Replacement supply lines, if the old ones are stiff or corroded
Troubleshooting the Kohler Simplice Kitchen Faucet
Most problems fall into a few categories: leaks, weak flow, and stiff or hard-to-control handles. The table below summarizes the usual causes and first checks.
| Symptom | Likely Cause | First Check |
|---|---|---|
| Drip from spout when off | Worn cartridge or debris on seat | Flush the line, then inspect and replace the cartridge if needed |
| Low water pressure | Clogged aerator or sediment | Remove and clean the aerator screen |
| Leak at base | Loose mounting nut or failed gasket | Tighten nuts evenly; check gasket seating |
| Handle hard to move | Cartridge mineral buildup | Soak or replace the cartridge |
| Water temperature wrong | Reversed supply lines or stuck cartridge | Confirm hot and cold hookup, then check cartridge |

Routine upkeep, including aerator cleaning, is covered in Kitchen Faucet Maintenance: Cleaning, Leaks and Aerators.
Common Mistakes to Avoid
- Buying before measuring the sink holes and deck thickness.
- Reversing hot and cold supply lines, which causes the handle to work backward.
- Using thread sealant where the manufacturer advises against it.
- Overtightening mounting nuts, which can crack a sink or distort the faucet base.
- Ignoring a small drip, which often means the cartridge is starting to wear.
- Skipping the flush step after installation, leaving debris to clog the aerator.
Tips for Long-Term Performance
Flush new supply lines for a minute before connecting them to the faucet to clear debris from the water line. Wipe the faucet with a soft cloth and mild soap rather than abrasive cleaners, which can dull finishes over time. If your home has hard water, clean the aerator every few months. Keep your original packaging or a photo of the model label, since it will make ordering replacement parts much faster.

FAQ
Is the Kohler Simplice kitchen faucet easy to install?
Most homeowners with basic plumbing skills can install it in an afternoon. The biggest challenges are reaching the mounting nuts and dealing with stiff old supply lines.
How do I know which Simplice model fits my sink?
Compare the number of sink holes, the deck thickness and the required hole diameter listed by the manufacturer against your sink. Confirm the model number before ordering.
Why is my Kohler faucet dripping after installation?
A new install can drip if a supply line is loose, the gasket is not seated, or debris is stuck in the cartridge. Check connections first, then flush the line.
Can I replace only the cartridge?
In many single-handle designs, yes. Shut off the water, remove the handle and retaining clip, and pull the cartridge. Always match the cartridge to the exact model.
Why is water flow weak from my Simplice faucet?
The most common cause is a clogged aerator. Unscrew it, clean the screen, and rinse it. If flow stays low, check the shutoff valves for partial closure.
Do I need plumber’s tape on the supply lines?
Follow the manufacturer’s instructions. Many supply line connections seal with a rubber washer and should not be taped. Using tape where it is not needed can cause leaks.
When should I call a professional?
If you find corroded shutoff valves, damaged sink surfaces, or water damage under the cabinet, consult a licensed plumber before continuing. Structural or water damage should be assessed by a professional.
Conclusion
The kohler simplice kitchen faucet is approachable to install and maintain when you measure carefully and follow the manufacturer’s steps. Confirm fit before buying, work methodically during installation, and address small drips or flow issues early. Keep your model information handy so replacement parts are easy to find when you need them.
