How do I remove grohe euromix 33857 faucet?

Purchase a set of tub and shower wrenches (sockets) as shown below.


Disconnect and remove sprayer hose if applicable.

Disconnect supply hoses from stop valves.

Select proper size socket to fit the nut holding the faucet in place.

Slide the socket up the supply tubes to insure you have correct size.

The sockets will fit one inside another (called stacking). Put one inside another until they are long enough to reach below the sink bottom.

Put a #2 Phillips screwdriver (or the tool that comes with sockets) in the hole in the bottom one and turn.
