FAQs

Does this set include the showerhead and hose?

This product is the exposed thermostat mixer valve. Depending on the specific retailer package, the hand shower and hose may need to be purchased separately.

Can I install this without drilling?

Yes, this model is compatible with GROHE QuickGlue technology, which allows for secure mounting on tiles, glass, or stone without drilling.

What is the function of the 38°C button?

The SafeStop button acts as a safety override to prevent accidental scalding, ensuring the water does not get dangerously hot unless manually adjusted by the user.

How do I clean the chrome finish?

Clean with a soft, damp cloth and mild soap. Avoid acidic cleaners or scouring pads that could scratch the chrome surface.

What happens if the cold water supply fails?

The thermostatic cartridge is designed to shut off the hot water flow automatically if the cold water supply is interrupted, providing protection against scalding.

Troubleshooting

Water temperature is not consistent

Check that the supply lines are not reversed and ensure the filters inside the connections are free of debris.

Low water flow from showerhead

Inspect the showerhead for mineral buildup or blockage and check that the shut-off valves are fully open.

Temperature does not exceed 38°C

The SafeStop button is active; press and hold the button while turning the handle further to bypass the default limit.

Pros and Cons

Pros

  • Consistent water temperature prevents scalding
  • Cool-to-the-touch surface enhances bathroom safety
  • Easy installation with included specialized tool
  • Optional drill-free mounting prevents tile damage

Cons

  • Requires compatible exposed plumbing layout
  • Safety limiters may require adjustment for specific user preferences
  • Not suitable for all gravity-fed systems without proper pressure balance

Setup, Compatibility & Care

To install, ensure your wall connections are spaced correctly for standard exposed thermostat mounts. Use the provided GROHE QuickSpanner to tighten unions, being careful not to overtighten and damage the washers. If opting for the drill-free method, ensure the mounting surface is thoroughly cleaned and dried before applying the adhesive system.

For care, wipe the chrome finish regularly with a soft, damp cloth to maintain its shine. Avoid using abrasive sponges, harsh chemicals, or descaling agents that contain hydrochloric or acetic acid, as these can strip the finish and damage the internal thermostatic cartridge.
