Wholesale Plumbing Supply

What Wholesale Plumbing Supply does

Wholesale Plumbing Supply Co. (WPSCO) is a third-generation, family-owned plumbing products distributor founded in 1957 by Jerome D'Angelo and headquartered in the Greater St. Louis region. The company sells a broad catalog of bath and kitchen plumbing fixtures — including sink faucets, bathroom sinks, bath furniture/vanities, toilets and bidets, tubs, tub faucets, showering, steam and sauna, kitchen faucets, kitchen sinks, water filtration, and disposals — sourced from major manufacturers such as Kohler (~19,462 SKUs), Elkay (~6,616), Delta (~5,042), Moen (~2,748), MTI Bath (~8,033), and Brizo (~2,400), among others. It operates 11 physical showroom/branch locations across Missouri and Illinois plus a dedicated Premier Plumbing Studio showroom in Saint Louis for design consultation, and runs a company-owned fleet of 50 trucks that provides complimentary delivery to job sites throughout the region.

WPSCO generates revenue through wholesale and retail distribution of plumbing products under a quote-based pricing model ('Call for Pricing' on most catalog items), serving two primary customer segments: professional plumbing contractors and builders, and consumer/homeowner renovators. The go-to-market motion is sales-led and relationship-driven, combining showroom visits, an outside sales representative, phone, email, and a structured 6-step consultation-to-delivery process, with alliances to national buying groups The Commonwealth Group and Do-It Best supporting purchasing competitiveness. The company also operates two wholly-owned divisions — Capital Supply and Strubberg Plumbing & Electrical — that extend the family of companies into adjacent plumbing and electrical distribution.

The business is privately held with no external investment, no disclosed funding rounds, no M&A activity, and no public financial reporting. The Premier Plumbing Studio sub-brand and the announced new Alton, IL branch (Fall 2026) indicate ongoing geographic and service-line expansion within the Greater St. Louis metro and Metro East Illinois markets. There is no proprietary technology platform; the website (wpsco.com) functions as a product catalog and brand directory rather than a transactional or AI-enabled system.

Comparable as an alternative purchasing channel for both consumers and pro contractors, with significantly broader assortment and pricing power.
