Sink Installation

This page covers installing and replacing sinks of every mounting style, kitchen and bath, including the full reconnection underneath: faucet, drain, trap, stops, and the disposal or dishwasher where the sink hosts them. Counter fabrication and cabinet modification are partner trades, named plainly where a chosen sink requires them.

What the installation settles:

• Mounting and support. Drop-ins clamp to the counter; undermounts hang on adhesive and clips rated for the bowl's filled weight; farmhouse sinks bear on built support inside the cabinet. Each style's support gets verified before the sink's weight tests it the hard way.
• The opening's honesty. New sink versus existing cutout: same-size swaps drop in; a bigger bowl needs counter work, a smaller one needs a different plan entirely. Measured before purchase, ideally, and before demolition at minimum.
• Drain geometry. Bowl depth changes where the drain leaves. A deeper replacement can drop the outlet below the existing trap arm, forcing a re-plumb of that short run. The under-cabinet look-ahead catches it while it is still a footnote.
• The reconnection stack. Faucet set (often easiest before the sink lands), stops tested and renewed as needed, trap aligned and remade with fresh washers, disposal remounted on its flange, dishwasher connections restored. The sink is one part; the stack is the visit.
• Sealed and soaked. Rim or joint sealed per mounting style, then the full test: bowls filled and released, connections touched dry, sprayer and accessories run. The sink proves itself wet before the tools leave.

How styles change scope:

• Drop-in and undermount. The kitchen mainstays. Drop-ins are the contained swap; undermounts add support and sealing rigor and usually pair with counter-side coordination.
• Pedestal and wall-hung. Bathroom fixtures that expose almost nothing, which means rough-in positions must land inside the pedestal's shadow, and wall carriers matter for hung bowls. Precision projects in a small footprint.
• Farmhouse and specialty. Apron fronts need cabinet modification and serious support; vessel sinks change faucet heights and drain types. These are chosen-for-looks fixtures whose plumbing consequences get budgeted, not discovered.
• What drives the number. Mounting style above all, then the reconnection stack's condition (old stops, tired traps, a disposal due for its own decision) and any counter or cabinet work the chosen sink demands from its partner trades.
