Kraus Kitchen Sinks and the Under-Sink Water Filter: What Kraus Buyers Need to Know
Kraus (Woodbury, New York) is a premium kitchen and bathroom fixture brand known for its stainless steel undermount kitchen sinks, commercial-style kitchen faucets, and bathroom vanities. Kraus does not manufacture water filters, but its kitchen sink designs are directly relevant to water filter installation: the number of pre-drilled sink holes determines how easily a dedicated filter faucet can be added without drilling. Understanding Kraus sink configurations helps buyers pair a Kraus sink with the right under-sink filtration setup.
Kraus Sink Hole Configurations for Filter Installation
Standard Kraus undermount kitchen sinks come in 1-hole, 2-hole, and 3-hole configurations. The key for filter buyers: a 3-hole or "deck-plate" configuration typically includes an unused 4th hole for accessories (soap dispensers, air gaps, or filter faucets). Kraus single-hole sinks (most common) require drilling a new 1-3/8" hole for a dedicated filter faucet -- possible in stainless steel with a standard step drill bit, but requiring caution and the correct tool. Kraus provides a pre-drilled mounting template for accessory holes on request for select sink models -- contact Kraus customer service (1-800-775-0703) before drilling.
Kraus Kitchen Faucets Compatible with Under-Sink Filter Systems
Kraus commercial-style kitchen faucets (KPF-1640, KPF-2730, KPF-2610) are single-hole faucets occupying the primary sink hole. When paired with an under-sink filter system requiring a dedicated faucet (APEC ROES-50, Waterdrop G3P800, Brondell Circle), the filter faucet occupies the sink deck's secondary hole or is installed through a countertop knockout. Kraus filter faucets (sold separately as KFF series, $50--$120) are designed to visually match Kraus kitchen faucet finishes -- Stainless, Black, Gold, and Brushed Brass -- creating a coordinated sink and filter faucet look that standard chrome filter faucets from RO kit suppliers do not provide.
