What affects the cost of garbage disposal installation?
New install vs. replacement
Swapping a same-brand unit onto the existing mount is fast; a first-time install needs a new sink flange and drain rework.
Drain plumbing changes
A taller or larger unit usually means re-cutting the tailpiece and repositioning the trap.
Electrical connection
A plug-in unit under the sink is simplest; hardwiring or adding a switch adds electrical work.
