Vanity Replacement
Handis vanity replacement is the same-footprint single-sink bathroom-vanity swap that resets a dated bathroom in one to two days from $900 plus the licensed plumber's separate invoice on the supply and drain reconnect. The 30-inch builder vanity with the molded-in sink that has been chipped at the front edge for nine years. The cabinet that has soft-bottomed under the trap from a slow drip nobody caught. The 1992 oak vanity sitting in a 2026 brushed-nickel-and-quartz bathroom. New vanity in, old vanity out, sink reconnected to the wall, mirror hung straight on a square strike — total project two working days including the plumber's half-day on the supply and drain. Cabinet widths from 24 to 48 inches on the same footprint as the old. The in-wall plumbing routes to a licensed Washington L&I plumber on a coordinated subcontract; we name the sub line by line on the quote.

How a Vanity Replacement Works
Six sequential steps from the booking-call spec confirmation through the final leak check — the actual sequence we follow on every same-footprint single-sink vanity swap.
Confirm Vanity Spec and Plumber Sub on the Booking Call
We confirm the existing vanity width, the new cabinet width, the new sink position relative to the old rough-in, and whether the supply and drain need a true rerough or finish in a simple reconnect. Plumber sub scheduled on the calendar in the same booking call so the rough-in day lands cleanly between demo and set.
Demo the Old Vanity and Top, Cap the Supply
Water shut off at the bathroom isolation valve or at the building main. Supply lines and drain trap disconnected at the wall, supply capped to prevent drip during the carpentry work. Old vanity, top, and sink lifted out as one assembly where the build allows, otherwise broken down on-site. Debris on a drop cloth, out to the hallway, out of the house.
Licensed Plumber Half-Day — Supply, Drain, and Any Rerough
The licensed Washington L&I plumber handles the in-wall supply line work (any flex, extension, or shut-off swap), the drain rough-in or off-set rerough if the new sink does not align with the old, and the trap assembly install. Plumber leaves the rough capped and pressure-tested, ready for the cabinet set.
Scribe the New Cabinet to the Wall, Shim, Plumb, Secure
Dry-set the new vanity. Scribe the end panel to the wall with a compass transfer, sand to the line with a belt sander, dry-fit again. Shim the toe-kick to level on the actual floor, plumb the cabinet face with a 4-foot level, secure to the wall with the appropriate stud anchor or rated toggle.
Install Countertop, Sink, Faucet, and Mirror
Countertop set on the cabinet (stock top installs same day; templated quartz returns from the fabricator after 1 to 2 weeks). Sink set in the top — undermount epoxied and clamped from below for a templated stone top, drop-in laid in on a bead of silicone for a stock top. Faucet set on the deck. Mirror or medicine cabinet hung centered over the sink with a level reference, anchored into stud or rated toggle.
Leak-Check, Re-Caulk, Walkthrough
Plumber returns for final supply hookup and trap connection if templated top sequence required two visits, or final connection same-day on a stock top. Water back on, every connection leak-checked under the cabinet and at the supply stop. Final perimeter caulk in 100 percent silicone at every wet-zone joint. Walkthrough with the homeowner, punch-list review, before the 30-day workmanship guarantee starts.
Vanity Replacement Pricing
Final pricing is Handis labor plus countertop material plus the licensed plumber's separate invoice on the supply and drain scope. Stock cabinet-included combos finish cheaper and faster than templated stone tops. Off-set drain reroute adds plumber time. Request a free estimate for an accurate quote.
Send us the existing vanity width and the new cabinet spec — we will quote Handis carpentry and the plumber sub before booking.
Estimate
Tell us the existing vanity width, the new cabinet width and brand (if you have picked one), the sink type (drop-in, undermount, or vessel), the countertop choice (stock, standalone, or templated quartz/stone), and any known constraints — an out-of-square corner, a tile floor you want to preserve, a previously leaking valve. We send a clear estimate with the licensed-plumber portion called out separately.
Customer Reviews
Vanity replacement reviews from real Handis customers.
1998 builder-grade 30-inch vanity in our hall bath, swapped for a 36-inch shaker-front with a quartz top. The new sink center landed three inches off the old drain so the plumber sub came in for half a day to off-set the trap. Handis ran the carpentry — scribed the end panel to the wall (which was 3/8 inch out of plumb across the run), set the cabinet level, installed the templated quartz top after the fab lead time. Total project ten days end-to-end, fixed price.
Master bath single-sink vanity replacement with a stock 48-inch standalone vanity from Wyndham. Same footprint as the old, sink centered the same place, so the plumber call was a simple reconnect — under the cabinet on the day of the install, no rerough. One and a half days, came in at the low end of the quote. The end panels are scribed perfectly to the walls on both ends.
Powder room vanity in our 1962 Bellevue split-level. 24-inch oak vanity from 1992 swapped for a custom 30-inch shaker. The bathroom corner is out-of-square by about 5 degrees, and the tech scribed the end panel and you cannot see a single shim line. The plumber came in for the off-set drain. Powder room looks new.
We found water damage when they pulled the old vanity — soft subfloor under a slow-dripping shut-off valve. They stopped, photographed, called us with the revised carpentry number and the plumber's revised number on the shut-off swap. We approved both, work resumed the next morning, no surprise on the final bill. That stop-and-call practice is why we will book Handis on the next project.
60-inch single-sink custom vanity in our 1929 Wallingford house — designed to sit in the original tile-floor footprint with the original 1929 plumbing rough that I refused to relocate. The carpentry guy scribed the end panel to a wall that is a half-inch out of plumb across the run; the plumber sub fitted the supply and drain to the existing rough-in. Looks like it was built into the house in 1929.
