Bathroom Vanity Replacement Guides

The vanity sets the tone of the whole bathroom, and it's often the first thing homeowners want to upgrade from the builder-grade original. These guides cover the swaps that involve more than a cabinet — going from one sink to two, changing the top, or switching to a floating vanity — and the plumbing and wall work each one requires.

A like-for-like vanity swap is straightforward; the projects that trip people up are the ones that move plumbing or change the footprint. A single-to-double conversion needs a second drain and supply set and enough wall to fit it; a top-only change depends on the existing cabinet being sound and standard-sized. Vanity work is usually part of a broader master bathroom remodel, and these guides explain how to plan it.
