Gather the Necessary Tools for GROHE Kitchen Faucet Installation

To install your Grohe kitchen faucet, you’ll need a few basic tools:

  • Adjustable wrench or basin wrench: To tighten the water supply lines and mounting nuts.
  • Plumber’s putty: To seal the faucet base to the sink and prevent leaks.
  • Flashlight: To see into dark cabinet areas.
  • Towels: To wipe up any drips or spills.
  • Eye protection: Safety glasses to shield your eyes.

Turn Off the Water

Double-check that the hot and cold water supplies under the sink are turned off before starting. It’s always a good idea to turn off the main water valve as an extra precaution.

Prepare the Sink Area

Clear everything out from under the sink so you have ample room to work. Place a towel on the bottom of the cabinet to kneel on. Remove any remaining putty or plumber’s tape from the old faucet installation. Clean the area well.

Install the Faucet

Feed the water supply lines and the sprayer hose (if applicable) up through the sinkhole. Apply a thick rope of plumber’s putty around the base of the faucet. Place the faucet in the sinkhole and press down firmly to adhere to it.

Connect the Water Supply Lines

Hand-tighten the hot and cold water supply lines to the correct faucet ports. Then fully tighten with your wrench. Connect the lines to your water shut-off valves and turn the water back on. Check for any leaks and tighten as needed.

Test Your Work

Turn the faucet on and check that the hot and cold water is flowing properly and at the correct temperature. Ensure the sprayer (if applicable) is also functioning well. Congrats! Your Grohe kitchen faucet is installed!

Selecting the Right Faucet Location for Optimal Functionality

The location you choose for your new Grohe kitchen faucet is crucial for its functionality and your convenience. Consider the following factors to select the optimal spot:


Make sure there is enough space between the faucet and the backsplash or countertop edges for unobstructed movement of pots and hands. A good rule of thumb is to leave at least 6 to 8 inches of clearance on each side of the faucet base.

Sink position

Consider where your sink is placed – under a window, in a corner, or mid-counter. A faucet located off to one side may make the other side difficult to access or splash water outside the sink. Center placement often works best for most sink and countertop configurations.

Ease of installation

Choose a location that will allow easy installation and access to water supply lines. Pull-down and pull-out faucets require space for the hose to fully extend. Make sure there are no obstructions underneath or behind the countertop that could hamper installation or damage water lines during drilling.

Splash zone

Consider the splash zone – the area where water is most likely to splash outside the sink during use. Select a spot that will minimize excess splashing and puddling on the countertop or backsplash. Pull-down faucets may require more splash-free space than a standard faucet.

By considering these factors before installation, you’ll choose a faucet location that maximizes functionality, convenience, and a clean, splash-free space. Your new Grohe kitchen faucet will serve you well for years to come, in the perfect spot.

Prepping the Sink for New Faucet Installation

To install your new Grohe kitchen faucet, you’ll first need to prepare your existing sink. This involves removing your old faucet and ensuring your sink base is clean and ready for the new installation.

Shut Off the Water Supply

The first step is to locate the shutoff valves under your sink that control the hot and cold water lines. Turn both valves clockwise to cut off the water supply to your faucet. Test your faucet to ensure the water is off before starting to remove anything.

Remove the existing faucet.

If your old faucet has detachable supply lines, unscrew them from the faucet body and remove them. You may need pliers or a wrench to loosen stuck connections. If the supply lines are soldered on, you’ll need to cut them to remove the old faucet. Either way, place a bucket or towels under the sink to catch any remaining water that may drip during removal.

Clean and Dry the Sink

Wipe down the sink area to remove any dirt or debris. Scrub any built-up gunk around the faucet holes and rinse well with water. Dry the entire area with a clean cloth to prepare for your new faucet installation.

Check for Additional Components

Some faucets come with additional components like sprayers, soap dispensers, or hot water dispensers. Make sure you have all the parts for your specific Grohe faucet model. You may have ordered or purchased them separately, so gather everything together before starting the installation.

Optional: Add Plumber’s Putty

If your Grohe faucet does not come with a gasket for sealing the faucet to the sink, you will need to apply the plumber’s putty. Roll the putty into ropes that will fit around the faucet holes in your sink. Place the putty ropes under the base of the faucet around the holes. The putty will form a watertight seal as you tighten the faucet onto the sink.

With your sink prepped and all parts in hand, you’re ready to install your new Grohe kitchen faucet. The following steps will walk you through connecting the water supply lines, attaching the faucet to your sink, and turning the water back on. If you run into any issues, refer to your faucet’s installation manual or give Grohe’s customer support a call.

Step-by-Step Guide to Removing the Old Faucet

Now that you have the necessary tools and parts, it’s time to remove your old faucet. This may seem intimidating, but by taking it step-by-step, you’ll have the new faucet installed in no time.

Turn Off the Water Supply

The first thing you need to do is locate the shutoff valves under your sink and turn off the water supply. This will prevent water from spraying out when you disconnect the faucet lines. If you have trouble finding the valves or shutting off the water, it may be best to call a plumber to handle this step.

Disconnect the Supply Lines

Check how your current faucet is attached to the water supply lines while the water is turned off. Most likely, it uses compression fittings, which need the nuts to be loosened in order to release the compression washers or threaded connections, in which case you can remove the connecting nuts. To remove the nuts and separate the lines from the faucet, use pliers or a wrench.

Remove Mounting Hardware

Next, look underneath your sink to locate the mounting bracket or nuts holding the faucet in place. Unscrew any mounting nuts or bolts with a wrench until you can lift the old faucet out. Be very careful not to drop anything down the drain during this process! Some faucets may also have sealant or putty around the base; use a putty knife to scrape this away.

Clean and Dry

With the old faucet removed, use a clean rag to wipe away any remaining debris or sealant around the sinkhole openings. Make sure the area is dry before installing the new faucet to ensure a tight seal.

Time for the New Faucet!

You’re now ready to unpack your new Grohe kitchen faucet and complete the installation. Simply follow the instructions included in the product packaging to attach the water supply lines, secure the faucet in place, and turn the water back on. Check all connections to ensure there are no leaks before using your new faucet.

Congratulations! You now have a sleek and modern Grohe kitchen faucet installed and ready to use! By methodically removing the old faucet yourself, you saved the expense of hiring a plumber. Enjoy your upgraded kitchen sink—you’ve earned it!

Installing the New GROHE Kitchen Faucet

Preparing for Installation

Before starting the installation, make sure you have all the necessary parts and tools. For a basic Grohe kitchen faucet installation, you will need:

  • New GROHE kitchen faucet
  • Adjustable wrench or basin wrench
  • Pliers
  • Pipe tape or pipe sealant
  • Flashlight
  • Towels to clean up any water spillage

Double-check that the water supply lines under the sink are fully shut off. Place a towel in the sink to catch any remaining water drips.

Removing the Old Faucet

Loosen the mounting nuts that secure the old faucet to the sink using the adjustable wrench. You may need to hold the faucet steady from above the counter with your hand or pliers while loosening the nuts. Remove any remaining putty or caulk around the base of the old faucet. Clean the area around the faucet holes in the sink to ensure a smooth installation of the new Grohe faucet.

Preparing the New Faucet

Unpack your new Grohe kitchen faucet and check that all parts are included. Apply pipe tape or pipe sealant to the threads of the water supply lines and mounting nuts. Feed the water supply lines through the faucet holes in the sink. Place mounting putty or caulk around the base of the faucet if installed in a single-hole sink. Press the faucet into place.

Securing and Connecting the Faucet

Hand-tighten the mounting nuts under the sink to secure the faucet. Tighten further with the basin wrench, being careful not to overtighten. Attach the water supply lines to your hot and cold shutoff valves. Turn the water back on slowly and check for any leaks. Tighten any connections as needed. Run the faucet to remove any debris.

Congratulations! Your new Grohe kitchen faucet is now installed and ready to use! Be sure to turn it on and test all spray functions to ensure proper operation before leaving the installation. Enjoy your new faucet and the convenience it provides in your kitchen!

Connecting the Water Supply Lines

Now that you have the new faucet and tools ready, it’s time to connect the water supply lines. This step will ensure your Grohe kitchen faucet has running hot and cold water.

Turn Off the Water Supply

First things first, locate the shutoff valves under your sink that control the hot and cold water lines. Turn them clockwise to shut off the water. Check that the water is off by turning on your faucet to make sure no water is flowing.

Connect the Hot and Cold Water Lines

You should have two braided stainless steel supply lines that came with your Grohe faucet. Connect the line with the blue marking to your cold water shutoff valve and the red line to the hot water valve. Make sure the end of the supply line with the nut goes onto the shutoff valve, and the end with the coupling attaches to the faucet. Tighten the nuts with an adjustable wrench or pliers.

Attach Water Supply Lines to Faucet

Next, attach the other end of the supply lines to the correct hot and cold ports on your faucet. The hot water supply line goes into the port marked with an H,” or red dot, while the cold water supply line goes into the port marked with a C,” or blue dot. Once the lines are screwed on, tighten firmly with your wrench, but be careful not to overtighten.

Turn the Water Back On

Finally, turn the water back on by turning the shutoff valves counterclockwise. Check for any leaks under the sink and tighten any connections as needed. Once everything looks good, turn on your new Grohe faucet to flush out any debris. Your Grohe kitchen faucet installation is now complete, and you can enjoy clean, refreshing water with the turn of a handle!

If you run into any issues or have additional questions regarding your Grohe faucet installation, don’t hesitate to contact Grohe customer service or consult a licensed plumber. Following these instructions properly will ensure you get many years of service from your high-quality Grohe kitchen faucet.

Mounting the Faucet to the Sink or Counter

Mounting the faucet to the sink or countertop is one of the final installation steps. You’re in the home stretch! By now, you’ve turned off the water supply, disconnected your old faucet, and cleaned the mounting area.

Attach Mounting Hardware

Locate the mounting hardware in your Grohe faucet box. This typically includes mounting bolts, washers, and wingnuts. Attach one mounting bolt to each of the pre-drilled holes in your sink or counter. Add a washer over each bolt and hand-tighten a wingnut to secure it in place.

Connect Water Lines

Next, connect the hot and cold water supply lines to the appropriate faucet inlets. The hot water inlet is usually marked with a red tag or label. Tighten the connections securely with an adjustable wrench or pliers. Once connected, turn the water back on and check for any leaks. Tighten as needed.

Position the Faucet and Secure

Place your faucet over the mounting bolts so the water inlet tubes feed down through the sink holes. Add washers and wingnuts over the bolts and hand-tighten to loosely hold the faucet in place. At this point, you want to ensure the faucet is positioned exactly where you want it before fully tightening the wingnuts.

Test the Installation

Turn the water back on and test your new GROHE faucet to ensure there are no leaks and that hot and cold water are flowing properly. Tighten any connections as needed. Once everything is functioning correctly, you can fully tighten the wingnuts under the sink to securely mount the faucet in place.

Congratulations, you’ve successfully installed your new GROHE kitchen faucet! With high-quality, durable materials and a simple installation process, you’ll be enjoying your new faucet for years to come. Let the chef in you get cooking—your kitchen is ready!

Testing for Leaks and Ensuring Proper Operation

Now that your new GROHE faucet is installed, it’s time to test it out and make sure everything is working properly before using it.

Turn on the water supply

Double-check that the hot and cold water supply lines under the sink are fully open. Then turn on the water at the faucet handle(s) to allow water to run from the spout for a few minutes. This will flush out any debris in the lines and ensure water is flowing freely.

Check for any leaks

Inspect all connections and supply lines closely for any signs of dripping or pooling water. Tighten any nuts or connections slightly if needed. It’s best to catch any leaks now before they become bigger problems! Once everything looks dry, turn the faucet off.

Test hot and cold water

Turn the handles to run the hot and cold water separately to make sure you’re getting the proper temperature from each. The hot water should be comfortably warm within a few seconds. If not, there may be an issue with your water heater that needs attention.

Ensure proper handling operation

Test that the faucet handles turn smoothly and control the water flow as intended. The water stream should go from a trickle to a steady flow as you turn the handles. If the handles are stiff or not operating correctly, they may need to be tightened or repaired. Refer to your faucet’s installation guide for specific instructions.

Check sprayer (if applicable)

For faucets with a pull-down sprayer, test to make sure the sprayer hose retracts freely and the different spray functions (stream, spray, pause) work properly when the trigger is pressed.

Once everything checks out, your new GROHE kitchen faucet is ready to make your cooking and cleaning tasks more efficient and stylish. Be sure to refer to the care and maintenance instructions to keep your faucet working great for years to come. Let the water run if it’s been off for a while and enjoy your new upgraded kitchen!
