The Delta Dryden 556-MPU-DST is a contemporary single-handle bathroom faucet with angular, architectural lines suited for modern and transitional bath spaces. The taller 7-15/16-inch spout height provides generous clearance for vessel sinks or deeper basins. DIAMOND Seal Technology delivers a ceramic disc valve rated for 500,000+ uses — twice the industry standard — while minimizing leak points. At 1.2 GPM, the faucet earns WaterSense certification. The included metal push pop-up drain assembly is ADA compliant and finish-matched. Pre-attached InnoFlex PEX supply lines and 3/8-inch compression fittings make for a straightforward installation on 1- or 3-hole 4-inch decks.
Is the Dryden 556-MPU-DST suitable for vessel sinks?
Yes. At 7-15/16 inches tall, the Dryden 556-MPU-DST has more clearance than lower-profile faucets like the Cassidy or Trinsic single-handle models. This extra height makes it a practical choice for above-counter vessel sink installations where more vertical reach is needed.
What finish options are available for the Dryden 556-MPU-DST?
The Dryden 556 is available in Chrome, Champagne Bronze, Brilliance Stainless, Matte Black, and Venetian Bronze. Each finish variant includes a matching-finish metal push pop-up drain assembly.
Does the Dryden faucet use the same valve as other Delta bathroom faucets?
Yes. The 556-MPU-DST uses Delta's DIAMOND Seal Technology — a ceramic disc cartridge with a diamond-infused contact surface that is tested to 500,000+ uses. This is the same valve platform used across Delta's mid-tier bathroom faucet lineup including Cassidy, Trinsic, and Lahara.
What is the hole requirement for the Dryden 556-MPU-DST?
The faucet is designed for single-hole installations on 4-inch center decks. An optional deck plate is included for covering two extra holes in a 3-hole sink deck. The supply connections use standard 3/8-inch compression fittings.
