This deep, even layered chrome surface creates a luminous and mirror like sheen.
  • SilkMove Cartridge: The rich and smooth handling of our single lever faucets conveys pure quality. As you change the temperature from hot to cold, one ceramic disc glides effortlessly across the other with absolute precision. These cartridges are manufactured in a high-tech process and feature discs made from a space-proven ceramic alloy. The SilkMove cartridge is yet another example of design and technology fusing to bring you an enhanced water experience.
  • Grohe WaterCare: With the constant challenge of providing faucets that perform to the highest standards while leaving the smallest environmental foot-print possible, Grohe has created a series of “WaterCare” faucets. These faucets use up to 30% less water than the industry standard 2.2 GPM models while surpassing strict guidelines when it comes to performance.

Grohe 20 121 Reviews

Rated 5 out of 5 by from A great faucet and a great buy! I purchased the faucet and matching handles for a recent bathroom remodeling project. The faucet and handles are fantastic! The quality is outstanding. Their feel is solid and heavy, no one will every say the handles feel cheap. The faucet and handles are better than what you can buy at any of the big-box stores.

Rated 5 out of 5 by from Wow! Love the water flow! I never felt water come out of a faucet like it comes out of this one. It's so awesome. It's smooth and just...water. All water. The pressure isn't what I would call "high", but it is good, and for a bathroom, who needs super high pressure? My husband and I are both big fans after only a month of use. It is very easy to clean - no seams on the neck! - and stays shiny pretty easily.

Rated 5 out of 5 by from GREAT, well-made faucet. I shopped in some brick and mortar stores first, talking to actual plumbers and all of them said Grohe is the best way to go for affordable, high quality faucets. I looked at over 300 faucets (from varying brands) online before I found this one. It's the perfect transitional fixture?not too modern and not too ornate. Nice clean lines but has a lot of style. We had two "unexpected" major bathroom renovations due to a surprise 3 year old leak, and used this this fixture in both the master and guest baths. Looks so good we are replacing the faucet in the 3rd bathroom. This is a VERY good value for your (my!) hard earned money.

Rated 5 out of 5 by from Grohe Quality Grohe is a bit pricey, but high quality. Remodeled a bathroom a few years ago with Grohe fixtures and went back again for this second bathroom.

Rated 4 out of 5 by from Nice Appearance Faucet is very nice. Valves operate smoothly. I get a high pitch wine from one valve. Very unpleasant. The drain plug does not sit in the center of the drain. Although is does work very well.

Rated 5 out of 5 by from Well made product Well made from solid materials, brass, chrome construction (no plastic parts). A bit harder to install than some others but the end result is worth the extra effort.

Rated 3 out of 5 by from deceiving photo I was fooled by the product photo of the wide handled faucets I just purchased. Package arrived without handles! They turn out to be another $41 per pair! That stinks.

Rated 3 out of 5 by from nice looking Nice looking faucet . Only complaint is that the water pressure is low and this was dissapointing.

  • do the handles move towards the back splash at all?do I need clearance on the deck...or do they move towards the sink to turn on?

    A. The Grohe 20 121 handles move forward toward the sink.
  • does the grohe 18027 handle fit this ?

    A. The Grohe 20 121 uses the 18 083 or the 18 084 handles.
  • I have a Happy D. #041710 washbasin and concerned and I don't know what the counter thickness is. Will this Grohe 20 121 fit?

    A. As long as your washbasin is drilled for a 3 hole faucet with 8" centers the Grohe 20 121 should fit your washbasin.
  • which towel bar and tissue holder should I purchase to get the best match with this faucet that I just bought in brushed nickel?

    A. Grohe Essentials Accessory kit would be a good purchase to match this faucet. 40 344 is a complete accessory kit available at a great price.
  • Which handle is which? Can I use other Grohe handles?

    A. The Grohe 18 083 are the lever handles and the 18 084 are cross handles.
  • Can the Grohe 20 121 be installed on my new 1 1/4 inch granite countertop? The spec indicates a max counter thickness of 1 3/16 inches which would be a hair less than 1 1/4 inches. Is there a converter kit available? Thank you!

    A. The maximum counter thickness is 1 3/16" on the Grohe 20 121 and this may not fit on a 1 1/4" counter top. It is possible to not use 1 of the 2 washers underneath to make up for the difference but this is not recommended.
  • Does this set fit any three hole sink?

    A. The Grohe 20 121 will fit any 3 hole sink with at least 8" centers.
  • is the stopper included?

    A. The Grohe 20 121 does come with a pop up.
  • What supply hose thread size fits these valves?


    The Grohe 20 121 uses a standard ½” connection.       

  • Does this include the two handles?


    The Grohe 20 121 does not include the handles.
