Celebrity Kitchens You'll Love

Double islands with prep sinks show up in nearly every celebrity kitchen, and they are the single most plumbing-intensive feature: new supply, drain and vent, plus a disposal circuit.

Pot fillers over the range look extravagant and cost surprisingly little to add during a remodel, as long as someone runs the line before the backsplash goes on.

Filtered water taps, under-counter ice makers and instant hot water dispensers are all realistic in an ordinary kitchen, and all three need a dedicated connection.

Apron-front sinks are the most requested. If you want one, tell your plumber early, because the cabinet and drain height often need adjusting.
