A leaky faucet or problems with water flow are signs of a faulty sink cartridge. This means it may be time to take apart the faucet and replace the cartridge in the handle. Sometimes you may just need to clean the cartridge out.
If you are looking for a guide on how to remove Grohe faucet handles, you’ve come to the right place.
Their sleek design gives your bathroom a modern look, but it may leave you puzzled on how to dismantle it. Despite this, Grohe models are incredibly easy to repair and maintain.
The process is about as complicated as opening a jar of mayonnaise, and it should only take a few minutes. It doesn’t matter if you have a faucet with one handle or two handles; the steps are basically the same.
How to Remove Grohe Faucet Handles
Designs may vary, but all bathroom faucets are similar.
If you have a Grohe faucet, it is a cartridge faucet. A plastic or metal cartridge is used inside the faucet to control water flow with an up and down movement. Rubber gaskets and O-rings are used to form an airtight seal around the cartridge.
You will find these faucets in two flavors:
- Single-handle – uses a single handle and one cartridge for both hot and cold water.
- Double-handle – uses two handles and two cartridges, one each for hot and cold.
If you are looking to find more information on your product or have a question, you can check for the model number. The model number can be found hidden somewhere discreetly on the hardware along with the manufacturer’s name.
Replacing the Cartridge
The lifespan of a cartridge is 20 to 30 years, but it can get clogged or fail. If so, they need to be either cleaned out or replaced.
If the sink faucet is leaking from the lever handle, it could be from problems with the seal around the cartridge or the cartridge itself is failing. Another classic sign of cartridge failure is difficulty adjusting the water temperature. Clogged cartridges can also lower the water pressure, blocking the flow of water through the faucet.
Get the part number for your faucet model, then go to the Grohe website to find the specific replacement cartridge. You can purchase it directly from Grohe or another trusted retailer (such as Amazon). Reach out to their customer service with additional questions.
Local hardware stores will typically have these parts either in stock or available by order.

Taking Apart a Single-Handle Faucet
1. Shut Off The Water – to close the drain, you will need to shut off the water supply.
- Underneath the sink, you will find two shutoff valve handles. One for cold and one for hot. Turn them both to the closed position.
2. Access the Cartridge – dismantle the lever handle, and remove the housing for the cartridge.
- Now that the water is shut off, turn the faucet handle to the open position to remove any remaining air pressure or water in the fixture.
- Find where the bolt holding the handle down is located. It should be on the underside of the handle. There is a small plastic cover over the nut; remove it with the flathead screwdriver.
- Then use the allen wrench to remove the bolt.
- Pull upwards to remove the handle.
- Use the socket wrench to unscrew the nut. Use your hand to unscrew the nut on top of the cartridge. Then remove the cartridge.
- Make sure there are no seals or foreign objects inside the mixer.
- Ensure the seals are on and insert the new cartridge.
3. Turn on the Water – make sure everything is working.
- Turn the water back on. Underneath the sink, turn the shutoff valves to the open position.
- Try using the faucet to check if everything is working as it should.
Taking Apart a Double-Handle Faucet
If you have a double-handled sink, the process is exactly the same, except you will need to take off both handles.
The only difference will be in step 2: Access the Cartridge.
