Winter 2026 has a solid stretch of plumbing-focused events worth planning around, and this page covers 10 conferences running from January through March.
The list spans regional trade expos and contractor business programs, chosen because they draw plumbing pros at different stages, from technicians looking for product exposure to owners working on margins. The Home Services Summit in Las Vegas kicks things off mid-January with a broad contractor audience. KBIS 2026 runs in the same window and pulls significant attention from the plumbing and fixtures side of the trades. If you're based in the West or Midwest, several of these stops are within a reasonable drive, including the PHCC San Diego Trades Expo in Del Mar at the end of January and the PHCC Nebraska Trade Show in Lincoln in early February. Use this page to figure out which events fit your sales cycle before spots fill.
