Foundations is a Delta collection with bathroom, kitchen and shower pieces. The sink and kitchen faucets here use Delta’s rotating stainless steel ball control with replaceable non-metallic seats, and the sheets say all operating parts can be replaced from the top. Each sheet lists a lifetime limited warranty on parts and finish for home use, with shorter terms for commercial use. The B510LF, a sister single-handle bath faucet on the same sheet, is in our bathroom faucet guide.
Delta Foundations B501LF: single-handle centerset
Choose the Foundations B501LF for a three-hole bathroom sink with 4-inch centers and one lever. Delta’s spec sheet (media.deltafaucet.com) covers the B501LF and B510LF and lists a solid brass body, 1.2 gpm for the B501LF, exposed mounting on three-hole sinks with 4-inch centers, a metal pop-up drain, 1/4-inch O.D. copper supply tubing with 1/2-14 NPSM connections, and a handle that returns to neutral when the valve is off. The drawing shows a 4-1/4-inch reach, a 7-1/8-inch overall height to the handle, holes of 1-1/8 to 1-1/2 inches and a 1-1/4-inch maximum deck, with 2-1/2 inches recommended to the back splash.

Delta Foundations BT13410: tub and shower trim
Choose the Foundations BT13410 for a matching tub and shower on a Delta MultiChoice valve. Delta’s spec sheet (media.deltafaucet.com) covers the Monitor 13 Series trims: BT13010 valve only, BT13210 shower only and BT13410 tub and shower. It lists a 1.75 gpm at 80 psi shower head, use with the MultiChoice Universal rough valve body (R10000 series), back-to-back installation capability, a temperature-only handle with a field-adjustable limit into the hot zone, 120 degrees of handle rotation, parts replaceable from the front, and a 1/2-14 threaded tub spout. Delta describes the Monitor 13 trim as pressure balanced.
The valve is sold separately. Delta lists an RP77991 stem extension kit for an extra 1-3/4 inches of wall. On October 15, 2026, the standard new offer sold by Amazon.com showed In Stock with model BT13410, chrome. See our Delta MultiChoice trim guide for valve checks.

Check these before you order
- Hole count. The B501LF needs three holes on 4-inch centers; the B1310LF needs three on 8-inch centers; the B4410LF needs four, including the spray.
- Deck thickness. All three sink faucets top out between 1-1/4 and 1-7/16 inches, so thick stone tops may be too deep.
- Shower valve. The BT13410 needs a Delta MultiChoice R10000 rough valve in the wall.
- Tub spout. The BT13410 spout threads onto a 1/2-inch pipe; check the stub coming out of your wall, and note whether it is threaded or plain copper before install day.
- Back splash. Delta recommends 2-1/2 inches behind the B501LF and B4410LF.
Service parts and repairs
The Foundations sink and kitchen sheets describe a control that is built to be serviced: the sheets say all operating parts can be replaced from the top, and the rotating stainless steel ball sits on replaceable non-metallic seats. So a worn seat can be replaced from above the counter without changing the whole faucet. On the B501LF and B510LF sheet, Delta notes that models with PPU have a plastic pop-up and models with LH have no drain and no lift rod hole, so check the suffix if you order a replacement drain.
The shower trim sheet lists its own parts by number, including the RP102064 1.75 gpm shower head, and says the face of the valve’s plaster guard should be flush with the finished wall. If your wall is thicker, Delta’s RP77991 kit adds 1-3/4 inches of stem; for special finishes, Delta says to also order RP12630 escutcheon screws.
Which Foundations piece should you buy?
In the bathroom, the B501LF fits the common 4-inch sink. In the kitchen, pick the B1310LF for three holes or the B4410LF if a fourth hole is waiting for a sprayer. In the shower, the BT13410 dresses a MultiChoice valve. The Amazon listings we checked show Foundations pieces in chrome and in stainless, marked with an SS suffix, such as B1310LF-SS and BT13410-SS, so you can match the kitchen and bath to the same tone.
Quote the full model number with its suffix when you order, because the finish is part of the part number. For more Delta options, see our Delta kitchen faucet guide and our Delta bathroom faucet guide.
