Quick choosing guide

  1. Measure first: sink base and cutout, faucet hole pattern, rough-in heights, and trap/supply sizes.
  2. Pick the finish: match faucet and accessory finishes across the room for a cohesive look.
  3. Performance & code: check GPM, pressure-balance or thermostatic valves, ADA/Watersense where required.
  4. Complete the install: add supply lines, angle stops, drains, traps, escutcheons, and sealants for a leak-free finish.


Pro tips: Dry-fit and flush lines before final connections, use plumber’s putty or silicone per the maker, and replace supply lines when swapping fixtures. Vent fans should match room size in CFM and be ducted outside.
