Cassidy is a Delta collection that includes bathroom and kitchen faucets. The 4-inch centerset Cassidy 2597LF-MPU is covered in our Delta bathroom faucet guide and left out here. Every sheet below lists a lifetime limited warranty on parts and finish for home use, with shorter terms for commercial use, and each one asks for 2-1/2 inches of clearance to the back splash.
Delta Cassidy 3597LF-SSMPU: widespread
Choose the Cassidy 3597LF for a widespread sink with handles 6 to 16 inches apart. The spec sheet Delta links for this model, DSP-L-3597LF-MPU-LHP (media.deltafaucet.com), lists solid brass end valve and spout bodies, a three-hole mount, 1/4-turn handle stops, interchangeable hot and cold stems, Quick Snap installation, a metal pop-up drain and 1.2 gpm at 60 psi. The drawing shows a 5-13/32-inch reach, a 5-13/16-inch height, 4-5/16 inches from deck to aerator, holes of 1-1/8 to 1-1/2 inches and a 1-3/32-inch maximum deck that Delta says can be extended 1 inch with RP10612.
One note: that sheet covers the less-handle (LHP) version, with handles chosen separately. Delta’s product page for 3597LF-SSMPU names it a two-handle widespread faucet in stainless, so the handles come with this model. On October 15, 2026, the standard new offer sold by Amazon.com showed limited stock with model 3597LF-SSMPU, stainless.

Delta Cassidy 597LF-MPU: single handle
Choose the Cassidy 597LF for a single-hole sink. Delta’s spec sheet (media.deltafaucet.com) lists a solid brass body, 1.2 gpm, one- or three-hole mounting with an optional RP102236 escutcheon that is not included, a metal push pop-up drain with no lift rod hole, and 1/4-inch PEX supply lines. The drawing shows a 5-3/8-inch reach, a 6-3/4-inch height, about 5-1/16 inches from deck to aerator, holes of 1-1/8 to 1-1/2 inches and a 2-7/8-inch maximum deck.
The same sheet covers the taller 797LF riser model. If your basin sits on top of the counter as a vessel bowl, ask for the 797LF instead; its drawing shows an 11-3/4-inch height and the same 1-1/8 to 1-1/2-inch hole size. On October 15, 2026, the standard new offer sold by Amazon.com showed In Stock with model 597LF-MPU, chrome.

The drawing shows a 5-inch reach, an 8-1/2-inch height, 4-3/4 inches from deck to outlet and a 2-1/4-inch maximum deck.
Delta says it is not applicable for pedestal sinks, so check what sits under your basin first. On October 15, 2026, the standard new offer sold by eFaucets showed limited stock with model 3597-PD-DST, chrome.

Delta Cassidy 4197-AR-DST: pull-out kitchen faucet
Choose the Cassidy 4197 for a matching kitchen faucet with a pull-out spray. Delta’s spec sheet (media.deltafaucet.com) lists DIAMOND Seal technology, Innoflex supply lines, a Touch-Clean spray head with aerated stream or spray, a 54-inch braided hose with a hose weight, a 360-degree spout, a Euro-Motion handle that rotates forward only to avoid the back splash, 1.8 gpm, and one- or three-hole mounting.

Supply connections and parts on the sheets
The Cassidy sheets list the connections and service parts by number, which helps when you plan the install or a later repair. The 3597LF uses flexible Quick Connect hoses with 3/8-inch O.D. copper tubing and 1/2-14 NPSM inlets, and its less-handle sheet lists handle options H295, H297 and H298. The 597LF uses 1/4-inch O.D. PEX supply lines ending in 3/8-inch compression fittings, and both the 597LF and 3597-PD show the RP101630 drain.
The 3597-PD uses 3/8-inch PEX supply tubes with 3/8-inch compression fittings. The 4197 kitchen faucet uses Innoflex supply lines with 3/8-inch compression fittings and lists three add-ons: the RP71545 escutcheon, the RP71543 soap dispenser and the RP61607 adapter that drops the hose to 1.5 gpm. Compare these with your shutoff valves before install day so you buy the right connectors once.
Check these before you order
- Hole spacing. Widespread Cassidy faucets fit 6- to 16-inch centers; the single-handle 597LF fits one hole or three with the optional plate.
- Deck thickness. The 3597LF tops out at 1-3/32 inches unless you add RP10612; the 597LF allows 2-7/8 inches.
- Pedestal sinks. Delta says the 3597-PD is not for pedestal sinks.
- Back splash. All four sheets ask for 2-1/2 inches of clearance behind the faucet.
- Escutcheon. The 597LF and 4197 plates are optional; check whether your listing includes one before you plan to cover extra holes.
Which Cassidy faucet should you buy?
Start with the sink. A three-hole widespread sink takes the 3597LF, or the 3597-PD if you want a pull-down spray and do not have a pedestal sink. A single-hole sink takes the 597LF. In the kitchen, the 4197 matches the bath pieces and its forward-only handle helps when the faucet sits close to the back splash.
