For a compact single-hole basin, start with the Grohe Eurosmart S 32642003. Choose the Eurosmart M 23990003 for a higher outlet, or the Concetto L 2021700A for a compatible three-hole widespread layout. Match the sink’s holes, height clearance and reach before choosing the finish.

Grohe bathroom faucets compared
| Model / layout | Overall / aerator height | Reach | Best fit to investigate |
|---|---|---|---|
| Eurosmart S 32642003 / 1 hole | 6-5/8 / 3-3/4 in. | 4-5/16 in. | Compact single-hole basin |
| Eurosmart M 23990003 / 1 hole | 7-11/16 / 4-3/4 in. | 4-3/4 in. | More room below the outlet |
| Concetto L 2021700A / 3 holes | 10-7/16 / 6-5/8 in. | 6-1/16 in. | Widespread layout and taller spout |
The 32642 sheet (lixil.cdn.celum.cloud), 23990 sheet (lixil.cdn.celum.cloud) and 20217 sheet (lixil.cdn.celum.cloud) provide these dimensions and required hole counts. Start with your sink’s drilling, then compare height and reach. The S, M and L labels identify these product sizes; they do not replace a measurement of your actual basin.
Eurosmart S 32642003: compact single-hole choice
Choose the Eurosmart S 32642003 when you want the shorter of these two single-handle faucets. Its sheet (lixil.cdn.celum.cloud) lists a 6-5/8-inch height, 3-3/4-inch aerator height, 4-5/16-inch reach, one required mounting hole and 1.2 gpm. It also lists 21-1/2-inch nylon-braided flexible supply hoses and an included drain assembly.
That shorter body is a reason to consider it near a low shelf or mirror cabinet, provided the handle has room to move. Check the outlet position against the sink’s back ledge and inner bowl. A faucet can clear the shelf yet leave too little room for your hands below the outlet.
Skip it if you need a higher outlet or if that reach would land the stream too near the rear rim. Grohe’s product page (grohe.us) permits a compatible deck plate for a three-hole sink, sold separately; do not assume a plate comes with the faucet.
On October 15, 2026, the linked standard new chrome offer was sold by Amazon.com, showed stock and had an add-to-cart button. Its model and part-number fields both read 32642003.

Eurosmart M 23990003: more space below the outlet
Choose the Eurosmart M 23990003 when the compact S-size outlet sits too low for the basin arrangement you have planned. The M-size sheet (lixil.cdn.celum.cloud) lists a 7-11/16-inch overall height and a 4-3/4-inch aerator height. Its reach is also 4-3/4 inches, with one required hole and the same 1.2 gpm rating.
The difference is physical fit. The M outlet sits higher than the S outlet and extends farther from the mounting centerline. Compare both dimensions with your sink rather than treating the M as a performance upgrade. The documents do not establish that it rinses better or lasts longer. Both models use the same listed flow rate, so the extra height and reach are the reasons to move from S to M.
Skip it if the taller body or handle would interfere with a cabinet, or if its outlet would sit in the wrong place over the bowl. Grohe’s product page (grohe.us) lists flexible hoses and a drain assembly, plus single-hole installation or a compatible separately sold plate for a three-hole deck.

Concetto L 2021700A: three-hole widespread choice
Choose the Concetto L 2021700A if you need separate hot and cold handles in a compatible widespread layout. Grohe identifies it as an 8-inch widespread faucet. The sheet (lixil.cdn.celum.cloud) lists three required holes, 10-7/16-inch overall height, 6-5/8-inch aerator height, 6-1/16-inch reach, solid-brass body and metal lever handles.
This is a different mounting arrangement from the Eurosmart single-body faucets. Check the separation of your existing holes, the space around each escutcheon and access below the deck. The installation guide (lixil.cdn.celum.cloud) shows the separate side valves and spout assembly. Three holes alone do not prove that the faucet fits an existing sink.
Skip it if your deck has only one hole, lacks the required clearance, or if the tall spout reaches too far into a small basin. Its product page (grohe.us) lists a drain assembly. Confirm the exact mounting and drain arrangement before ordering rather than assuming a generic installation kit covers it.
On October 15, 2026, the standard new chrome offer was sold by eFaucets through Amazon, showed limited stock and had an add-to-cart button. The listing’s model and part number both matched 2021700A.

Check height and reach against the basin
Use the finished mounting deck as your reference for height. Overall faucet height tells you how high the body or handle reaches. Aerator height tells you where the outlet sits. Those measurements answer different questions, especially near a shelf or above-counter bowl.
For reach, measure from the intended mounting centerline toward the area where you want the water to land. Grohe describes angled aerators on the linked Eurosmart pages, so printed spout reach alone does not establish the exact landing point of the water. Check the outlet direction as well as its position. Check that location against the inner bowl rather than the countertop edge. Also leave usable room around the handle. Our single-hole bathroom faucet guide explains the fit checks for that layout.
For a vessel bowl, do not choose solely because a faucet looks tall. Compare the outlet with the bowl rim and the proposed mounting position. This guide does not establish a vessel-bowl fit for every L-size faucet. Use a dimensioned side view of the full basin-and-faucet arrangement before deciding.
Drain assemblies and under-deck space
The three exact product pages identify drain assemblies as included, but that does not establish compatibility with every basin. Check your sink’s drain opening, overflow arrangement and the supplied drain instructions. Do not discard an existing compatible drain until you understand what the replacement kit requires.
Look below the deck before buying. The Eurosmart sheets list 21-1/2-inch flexible hoses; compare their actual route with the shutoff-valve positions and any storage shelf. Avoid planning a hose path that depends on pulling a connection tight. For the Concetto, allow access to the separate side-valve connections as well as the center spout mount.
Follow the Eurosmart S guide (lixil.cdn.celum.cloud), Eurosmart M guide (lixil.cdn.celum.cloud) or Concetto guide for the exact assembly and flushing sequence. Our general faucet installation guide covers preparation. If a shutoff fails to isolate the water or a concealed connection moves, have a plumber assess it before proceeding.
Choose the exact version and keep its paperwork
The offers linked here are chrome. Check the full model number after choosing any finish or size on Amazon; a search-result title may describe a different variant. A faucet advertised with a similar collection name is not enough to establish the hole count, flow version or drain package.
Keep the model number and installation paperwork for later service. The single-handle Eurosmart and two-handle Concetto have different layouts; do not assume they share replacement cartridges or mounting parts. Use the maker’s exact parts diagram when a repair is needed.
Choose among these models by documented fit and handle preference. All three carry the same listed flow rate, so that specification does not give one a flow advantage over another. The rating is a maker specification, not a measured flow result in your home. If you are still comparing brands, our bathroom faucet guide covers broader choices.
Frequently asked questions
Which Grohe bathroom faucet needs one hole?
The Eurosmart S 32642003 and M 23990003 sheets each specify one required mounting hole. The Concetto L 2021700A sheet specifies three holes.
How is the Eurosmart M different from the S?
The M has a 4-3/4-inch aerator height and reach. The S has a 3-3/4-inch aerator height and 4-5/16-inch reach. Compare those dimensions with your basin; the size label alone does not establish fit.
Do these Grohe faucets include drains?
The exact product pages for these three picks identify drain assemblies as included. Confirm the delivered parts and their compatibility with the basin before installing.
Can a single-hole Eurosmart cover a three-hole sink?
Grohe’s linked Eurosmart product pages allow installation on a three-hole sink using a compatible deck plate sold separately. Check the exact plate and hole spacing before buying.
Is every L-size Grohe faucet suitable for a vessel sink?
Do not assume that. Compare the outlet height, bowl-rim height and reach using the exact faucet and basin drawings. The size name is not a universal vessel-sink fit claim.
How we chose
We compared Grohe’s exact-model specification sheets, product pages and installation guides for mounting holes, overall height, outlet height, reach and included drain assemblies. We checked standard new Amazon offers on October 15, 2026 for model, chrome finish, seller, stock and cart availability. We did not test durability, splash control or installation speed. An Essence candidate was excluded because its sheet contained conflicting dimension fields. Read our selection method and about Plumbing Picks.
