Best glass rinser for a kitchen sink

The CleanMate KGR-500 is the glass rinser I’d put on most kitchen sinks, and I’ve used it. Kraus publishes a full spec sheet for it, revised Sept 15, 2025, and the listing fills in the cup sizes.

It’s the widest of the three. The listing gives a minimum drinkware opening of 1½ in. and a maximum of 4¼ in., and calls it a 5 in. wide opening. That takes a 30 oz tumbler mouth that the Delta rinsers can’t cover.

Install detail is where Kraus pulls ahead. The sheet gives a maximum deck thickness of 2¼ in., a ⅜ in. compression connection, a 42 in. quick-connect nylon water line and an adapter tee. It also includes an optional spacer for sinks with a raised ledge.

The listing says it fits a 1¼ in. hole and works with limited backsplash clearance. That’s the typical size of a soap dispenser or side-sprayer hole you’re not using.

The safety lock is the feature I’d point a family to. Kraus calls it a ⅛ turn lock that prevents accidental activation: you press and turn to spray. A rinser that fires every time someone sets a glass on it will soak the backsplash.

Flow is listed two ways. The spec sheet says maximum 1.8 gpm at 60 psi; the listing says maximum 1.2 gpm. Either way it’s a short burst per glass, not a running tap.

Where it lost points: the warranty. Kraus’ sheet says 1 Year Limited Warranty, against Delta’s lifetime limited. It also has a dome-shaped screen washer at the inlet, worth checking if the spray ever weakens.

My call: if your counter is thick quartz or granite and you rinse wide cups, this is the one. Kraus also makes it in Matte Black and Spot-Free Brushed Brass.

Delta’s GR250 is the metal version of its glass rinser, and I’ve used it. Delta’s page calls it the Metal Glass Rinser and lists it in Arctic Stainless, Champagne Bronze, Chrome, Matte Black, Polished Nickel and Venetian Bronze.

That finish list is the reason to buy it. If your faucet is a Delta in a finish other than chrome or stainless, this is the rinser that matches it.

Delta gives the drinkware range as 1 in. to 3.6 in. across the opening. That covers baby bottles, wine glasses and most travel cups, but not the widest tumbler mouths.

The install specs are short: single-hole installation, 1.2 gpm at 60 psi, an overall height of 1½ in., and it connects to either the hot or cold supply. Delta’s page says it includes a 42 in. supply line and an adapter tee.

Where it lost points: Delta doesn’t publish a maximum counter thickness the way Kraus does, so it scored 7 on fit. And there’s no lock, so it scored 7 on splash control. Press a glass down on the actuator arms and it sprays.

Delta’s parts diagram (DPD-K-GR250, Nov 15, 2019) lists every replaceable piece: cover, actuator arms, foam gaskets, spacer, mounting nut, hose and tee. Those part numbers are what you’d ask for if one ever wears.

The warranty is the best here. The listing says it’s backed by Delta Faucet’s Lifetime Limited Warranty, and Delta lists the finishes as tested for corrosion resistance to at least twice industry standards.

Delta pitches it as a simple DIY replacement for a sink sprayer, soap dispenser or sink hole cover, so it’s an under-sink job with no counter work if a hole is already there.

My call: the subtle overhang Delta describes is what keeps the runoff in the bowl, so mount it at the sink edge, not back by the backsplash.

The GR150 is Delta’s original glass rinser, and I’ve used it. It does the same job as the GR250 with the same 1 in. to 3.6 in. drinkware range, in Chrome or SpotShield Stainless.

The narrow end of that range is its strength. A 1 in. minimum opening means the jets reach into a baby bottle or a slim water bottle that the Kraus, at 1½ in., doesn’t fit over.

Delta’s GR150 page states it’s tested and certified to NSF/ANSI Standard 61, the drinking-water safety standard, and notes the lined waterways in Delta faucets. That’s the only one of the three where the maker states the certification on the rinser’s page.

The install specs match the GR250: single hole, 1.2 gpm at 60 psi, 1½ in. tall, hot or cold supply. Delta says it includes a tee adapter, and the listing says the supply line is included. Delta calls it a simple DIY replacement for a sink sprayer, soap dispenser or hole cover.

The listing mentions Touch-Clean spray holes, which let you wipe off calcium and lime build-up with a fingertip. On hard water, that’s the maintenance you’ll do most.

It lost the same points as the GR250: no published maximum counter thickness and no lock. Its parts diagram, DPD-K-GR150 (June 24, 2020), adds a support washer the GR250 diagram doesn’t list.

The warranty is Delta’s Lifetime Limited Warranty, per the listing. The SpotShield Stainless finish, the listing says, resists water spots and fingerprints, which matters on something you touch with wet glasses all day.

Delta’s page lists it at 1½ in. tall above the deck, the same as the GR250, so either one sits low beside the faucet.

My call: for a house with a baby, this is the one. Rinse the bottle here, then wash it properly; a rinser blasts residue, it doesn’t sanitize.
