How to Take Apart a GROHE Bathroom Faucet

German-based company GROHE specializes in producing sanitary faucets. Ranging from kitchen faucets to bathroom ones, their range of products is quite huge. The biggest factor that separates them from the market competition is the use of a cartridge-based system.

Owners of GROHE faucets need to know the basics of taking them apart, just to be on the safe side.

The cartridge system effectively regulates water temperature and pressure. There are several steps to disassembling it:

Some GROHE faucets come with a cartridge system. And the cartridge system is helpful for regulating water temperature and pressure. For taking it apart, there are several steps you need to follow:

  • Turn the water off
  • Take the screw out
  • Detach the phalange
  • Remove the cartridge

The process should take approximately 15 minutes.

We highly recommend sticking to the manufacturer’s cartridges and products since those will fit better. Using the correct product also creates an improved seal. Instructions may vary from one GROHE faucet to another so always check the manual provided to alter the steps as required. Generally, here’s how to take apart a GROHE bathroom faucet.

Tools You Will Need

  • 32 mm box spanner (Alternative: Adjustable spanner)
  • 3 mm allen key
  • Flathead or Philips screwdriver depending on the faucet
  • New GROHE cartridge

6 Steps to Disassembling Your GROHE Bathroom Faucet

Step 1: Turn the Water Off

Turn off the water supply to the faucet in your bathroom – this is an essential step. A properly installed bathroom should have a shut-off setting under the sink. However, you can turn the water off directly by shutting off the house’s valve. 

Water moves through the cartridge you’re going to replace. In case you forget this step, the water will splash everywhere and you’ll have more work on clean-up duty.

Step 2: Raise the Lever

After the water is turned off, you have to raise the lever. This essentially releases any additional pressure or water still running along those lines. In addition, this step lets you find the screws you need for the next step. Make sure you let the water drain entirely before starting.

Step 3: Detach Screw

The lever is attached by a star-shaped screw. When the lever is raised, you must find a cover for the screw. Use a screwdriver to remove the cover. Once that’s done, bring out the 3 mm allen key. Turn it counterclockwise to remove the screw.

The small bits are the most important trinkets here so make sure to place them somewhere safe. Don’t forget them!

Step 4: Detach and Take Away the Phalange

If you did step 3 correctly, the lever should now be loose. Pull it in an upward motion to detach the lever from the base of the faucet. With the help of your screwdriver, remove the phalange.

Phalangers are attached by the sole power of pressure and mainly act as a trim piece covering open areas. 

Step 5: Remove the Nut

A nut is all that remains between you and the cartridge. Place your spanner of choice on top of the cartridge and use slight pressure to turn it counterclockwise. That should loosen it.

Step 6: Dismantle the Cartridge

With the above steps completed, you will now be exposed to the cartridge. A quick upward pull should make it budge without breaking a sweat. After that is removed, check the basin for any mildew or debris buildup.

Consider cleaning the basin in the middle. This improves overall water quality and pressure. Moreover, it adds longevity and functionality to the new cartridge.

Installing a New Cartridge

Time to install the brand new cartridge. At first, inspect it to make sure the seals are placed in the right spot. Line up the two tabs and insert them into the basin. The lining tabs part ensures the correct placement of the cartridge. If misaligned, a cartridge might fail, potentially damaging your faucet while you reinstall the other bits.

A GROHE faucet cartridge would last you anywhere between 20 to 30 years. But that doesn’t mean it’s immune to the occasional fail or clog. If that happens, just clean or replace it. Check to see if your sink faucet is showing leaks outside the lever handle. It probably is a seal issue near the cartridge or the part itself has failed.

One more sign of cartridge failure is sudden problems with water temperature adjustment. Low water pressure indicates a clogged cartridge.
