Bought a Vanity or Faucet at Ferguson or Central Arizona Supply? We Install It.

Norem Contracting installs vanities, tops, sinks and faucets bought at the Ferguson Home showrooms in Scottsdale and Mesa, at Central Arizona Supply's Valley showrooms, at a big-box store or online, and the plumbing connections are part of our contract, done to code. Replacing a vanity with the plumbing reconnected runs about $300 to $800 in labor in the Phoenix metro, before the cabinet and top. In Phoenix, swapping a fixture in its existing spot needs no permit, and moving or adding a sink does. We are a licensed Arizona general contractor, ROC #365090, and we are not affiliated with any of these stores.

• Any showroom, any brand. Ferguson Home, Central Arizona Supply, Floor & Decor, Home Depot, Lowe's, IKEA, Wayfair or a faucet maker's own site.
• The plumbing is on our contract. Angle stops, supply lines, the trap and the drain connection, done to code and leak-checked by the same company that set the cabinet.
• The wall behind it, too. Whatever the old vanity was hiding gets patched, textured and painted before the new cabinet covers it for another twenty years.
• Lights and outlets above the sink. A new vanity light, a GFCI receptacle or power for a lighted mirror, handled on the same contract, to code.
• Quick quotes by text or phone. Send a photo of the old vanity with the doors open and a link to the new one to (602) 492-1815, or call.

Where Do Valley Homeowners Buy Vanities and Faucets?

Mostly in two kinds of places: the plumbing showrooms, where the fixture lines run deep and a consultant helps match the parts, and the big-box and online stores. Below are the Valley locations each company lists on its own website as of October 2026. We are not affiliated with any of them, and we install what you buy.

Plumbing and kitchen-and-bath showrooms

• Ferguson Home, the Kitchen & Bath showrooms on North Hayden Road in Scottsdale and on East Baseline Road in Mesa
• Central Arizona Supply, plumbing showrooms in Phoenix on North 16th Street, in Scottsdale on North 90th Street, and in Mesa, Gilbert and Surprise, plumbing counters in Deer Valley and Apache Junction, and the Central Reserve appliance showroom in Scottsdale

Ferguson has folded its old Bath, Kitchen & Lighting Gallery name and build.com into one brand, Ferguson Home, so a Build.com order and a showroom order carry the same name. Both Ferguson Home and Central Arizona Supply sell lighting as well, and if a chandelier came home with the vanity, the Valley lighting stores we hang chandeliers from covers that side of the bathroom.

Big-box, warehouse and online

Home Depot and Lowe's carry vanities, tops and faucets in the aisle and many more online. Floor & Decor sells complete vanities, vanity bases and separate tops, with top sizes running from 25 to 73 inches. IKEA Tempe sells bathroom vanities alongside its kitchens. Then there are Wayfair, Amazon and the faucet makers' own sites. A vanity ordered online arrives in a carton somebody has to carry in and open, which is where shipping damage first shows, so we open it and check the parts before the old vanity comes out.

Will the Showroom Install It?

Usually not, and the showroom pages don't say they do. Ferguson Home's Scottsdale page describes product experts, appointment booking, a project tool for saving selections and a Pro account for trade pricing, and it says the showroom serves homeowners and professionals alike. It doesn't describe an installation service. Central Arizona Supply's locations page lists its Phoenix, Scottsdale, Mesa, Gilbert and Surprise showrooms alongside plumbing counters, with hours for each, and describes no installation service either. Either way, the install is a separate hire you make.

The order of work matters here. A vanity install is cabinet carpentry, plumbing, drywall and often a little electrical in a room the size of a closet, and those pieces only line up when one company holds them. We set the cabinet, connect the supplies and the drain, test for leaks, patch the wall the old vanity hid and swap the light above the mirror if it's going, all on one contract.

Do You Need a Permit to Replace a Vanity or Faucet in the Valley?

In Phoenix, not for a swap in the same spot. The city's Work Exempt from Permit list exempts the "replacement of water closets, valves or fixtures with new valves or fixtures complying with the conservation requirements of this code, except that a permit shall be required for the relocation of any valves, pipes or fixtures." The city's residential projects page says it more plainly: permits are required to move or add sinks, toilets and tubs, and replacing existing fixtures does not require one. A 36-inch vanity replacing a 36-inch vanity on the same drain is exempt. A second sink added for a double vanity is not.

Scottsdale draws the line somewhere else. Its home improvement page lists "repair or replacement of existing plumbing fixtures in the same location" under the minimum plumbing permit, while cabinets and countertops are exempt, and work completed without a permit is fined at double the permit fee. Mesa, Chandler, Gilbert, Tempe, Glendale and Peoria each publish their own lists, so check the city before assuming the Phoenix answer travels. Our guide to remodel permits in Phoenix walks the rest of the line for kitchens, bathrooms and walls.

What Should You Check Before You Buy a Vanity or Faucet?

Fit first, then the faucet. Many vanity problems that show up on install day were decided in the store, and each one below is easier to fix inside the return window than after the old cabinet is gone.

• Width against the toilet.The toilet has to sit at least 15 inches from its center to the side of the vanity, with 21 inches clear in front of it under the IRC and 24 under the Uniform Plumbing Code. Phoenix has adopted both codes, so plan to the larger number. Measure from the center of the toilet to where the new cabinet's side will land. A wider vanity that eats into that space is a fit problem no install fixes.
• Height.Ferguson Home's buying guide puts a primary-bath vanity at 36 inches, a guest bath at 32 to 34 and a kids' bath at about 30. A vessel sink adds its own height on top of the counter, so a vessel bowl usually pairs with a shorter cabinet.
• Faucet holes.A single-hole faucet needs one hole. A centerset fits three holes on 4- or 6-inch centers, and a single-hole faucet with its deck plate can cover a three-hole top too. A widespread faucet's handles and spout are separate pieces, with centers that can run from 8 to 16 inches, and a widespread won't fit a top drilled for a 4-inch centerset. A pre-drilled top narrows the faucet choice, so buy the two together.
• Flow rate.Phoenix's 2024 plumbing code amendments list 1.5 gallons per minute at 60 psi for private lavatory faucets and sink faucets, with 2.2 allowed only where one of the amendment's listed exceptions applies, and the city ties the change to EPA WaterSense. The permit exemption covers replacement fixtures that meet the code's conservation requirements. WaterSense labels bathroom faucets only, and EPA says it has no criteria for kitchen faucets, so a kitchen faucet's flow has to be read off its spec sheet: one rated 1.8 gallons per minute is over the 1.5 Phoenix lists for sink faucets.
• Lead-free certification.Federal law, as the EPA explains it, defines lead free as a weighted average of 0.25 percent lead across the wetted surfaces of a pipe, fitting or fixture, and since September 1, 2023 manufacturers and importers have needed lead-free certification. A marketplace faucet from a brand you have never heard of is worth checking before it goes on a drinking-water line.
• Wall-mount faucets.A wall-mount faucet needs a rough-in valve inside the wall. That's new piping, and in Phoenix relocating any valve or pipe takes a permit, so a wall-mount faucet turns a swap into a small remodel.
• Top sold separately.Some vanities come as two pieces, the cabinet and the top, and Ferguson's guide says the top has to be ordered to match the cabinet. Check that the top, the sink and the faucet drilling are all on the order.
• Floating vanities.A wall-mounted vanity needs a wall with stud support behind it, which in practice means wood blocking between the studs at the mounting height. If the blocking isn't there, the wall gets opened to add it, then patched. On a block wall the fasteners go into the block with masonry anchors, which changes the hardware and the day.

Which top holds up to Phoenix water?

The top takes the hard water every day, so the material matters more here than in most of the house. Porcelain takes in almost nothing and, because it isn't calcium carbonate, doesn't etch when it gets cleaned. Marble, travertine and limestone are calcium carbonate, and acid cleaners, the vinegar soak included, can dull or etch them. Marble still works on a vanity top if it is sealed and kept away from acidic cleaners, though it picks up etch marks over time. On the faucet, matte black shows white mineral spots and wants a wipe after use, while brushed nickel or stainless with a spot-resistant finish hides hard water far better.

Can the Old Top or Faucet Go Back On?

Sometimes, and it depends on the drilling and the footprint. A faucet in good shape can go onto a new top if the holes match its type, a centerset on a 4-inch top or a widespread on a top drilled for one, and if it meets the flow rate the city requires of a replacement fixture. Phoenix water scales valve cartridges over the years, so a reused faucet gets a look at its cartridge and new supply lines at minimum.

An old top can go back on a new cabinet only when the cabinet matches the old one's width and depth and the sink still lands over the drain. A top that was glued down doesn't always come off in one piece, so if keeping it matters, say so before demo and it comes off slowly with the adhesive cut first. The more common move is the reverse: keep the cabinet, which may be sound, and replace only the top, sink and faucet. That is a lighter job than a full vanity, and it still runs through the same stops, trap and caulk line.

What Goes Into Installing a Vanity Right?

Most of it happens before the new cabinet goes in. We shut the water off at the angle stops, disconnect the supply lines and the trap, cut the caulk line and pull the old top and cabinet. That exposes three things to check: the stops, the drain stub and the wall.

The stops are the small valves under the sink. Old multi-turn stops that haven't been closed in years can weep or refuse to shut all the way, and a vanity swap is the cheapest moment to replace them, with the water off at the house main, with quarter-turn stops and braided stainless supply lines. The drain stub decides where the new sink can sit. If the new bowl lands over it, the job stays a swap. If it lands a foot to one side, it's a relocation. The wall behind an old vanity is often unpainted, untextured drywall, sometimes with a water stain at the bottom, and we patch and texture whatever the new cabinet won't cover before it goes in, because once the cabinet is set nobody reaches that wall again.

Then the new cabinet goes in level off the high point of the floor, scribed to a wall that is rarely plumb, and screwed through its back rail into the studs. The back panel gets cut for the drain and supply stubs before the cabinet is set, not after. The top goes on with the faucet and drain assembly already mounted, where the deck is easy to reach, then the trap and supply lines get connected. We run the water hot and cold, fill and drain the bowl, and check every joint for drips before the top gets its caulk line at the wall.

Phoenix water and pressure

Phoenix water is hard. The city's 2025 water quality report puts total hardness at 172 to 302 parts per million, which is 10 to 17.6 grains per gallon, and every drop that dries on a faucet leaves that mineral behind. It collects in the aerator at the tip of the spout too, so a cleaned aerator is the first check when a faucet's flow drops. Finishes, softeners and glass are covered in our Arizona bathroom design tips.

Pressure is the other check. The code requires a pressure-reducing valve where static pressure exceeds 80 psi, and a gauge on a hose bib reads it in five minutes. High static pressure eats the cartridges and supply lines you just paid for, so the vanity visit is a good time to read it.

Lights and outlets above the vanity

The receptacle by the sink has to sit within 36 inches of the outside edge of each basin and be GFCI protected, and a lighted mirror or a new vanity light usually means a box or a circuit change. That electrical work is on our contract, to code, the same as the plumbing. See light fixture installation for the light itself.

Can You Install the Kitchen Faucet, Sink or Disposal Too?

Yes. Ferguson Home and Central Arizona Supply sell kitchen fixtures and appliances next to the bath lines, and a kitchen faucet swap is often the smallest job on a homeowner's list. Angi puts a standard kitchen faucet installation in Phoenix at about $287 on average, with most jobs between $162 and $412. A pull-down faucet with a heavy spray head or a separate filtered-water tap adds time under the sink, and a tap that needs a new hole adds a drilling step in the sink or the counter.

Kitchen faucets get the same flow check as bath faucets, since Phoenix's amendments list 1.5 gallons per minute at 60 psi for sink faucets. A disposal needs power at the sink, either a switched receptacle or a hardwired switch leg, and adding power where there was none is electrical work we handle on the same contract. In Phoenix, replacing cabinets and fixtures in existing locations with no new electrical or structural changes needs no permit, and moving the sink does. On a slab, moving a sink means cutting concrete, which our kitchen remodeling page prices out.

If the cabinets are coming out with the sink, our Sun City West cabinet installation shows how a counter and a working sink stayed in service through a full cabinet swap.

What Does Vanity and Faucet Installation Cost in Phoenix?

Labor to replace a vanity with the plumbing reconnected runs about $300 to $800 in the Phoenix metro, and the cabinet, top and faucet are on top of that. The rest of the table covers the lines that tend to ride along with a vanity.

A hall bath with a new vanity on the old drain, a new toilet and a vanity light swap lands around $690 to $1,780, toilet included, before the vanity, top and light fixture. Two lines decide whether a vanity job stays that small. The first is the drain: a sink that lands over the old stub is a swap, and one that lands a foot over is a relocation, which on a Valley slab can mean a tendon scan and then a saw cut through the concrete. The second is the wall, because a cabinet with a different footprint than the old one leaves drywall, paint and sometimes floor to finish.

A double vanity replacing a single moves both lines at once. The second sink is an added fixture, so it needs a new drain and supply, and in Phoenix an added fixture takes a permit. If that's the plan, price it as a small bathroom project rather than a vanity swap, and our bathroom remodel cost guide shows where those lines land.

How Does a Vanity Install Go With Us?

In eight steps, and the first three happen before the old vanity comes out.

1. Text or call. Send a photo of the existing vanity with the doors open, so the drain and stops show, the width of the wall and a link to the new vanity and faucet. We reply with a quote.
2. Check the fit. Toilet clearance, where the drain lands against the new drawers (Ferguson's guide says the doors and drawers should not be blocked by the plumbing), the faucet drilling on the top and the faucet's flow rating, flagged while the return window is still open.
3. Open the boxes. The new cabinet, top and faucet come out of their cartons and get checked for shipping damage and missing parts before the old vanity is touched.
4. Shut off and remove. Water off at the stops, supplies and trap disconnected, the old top and cabinet out, and the stops, drain stub and wall looked over.
5. Prep the wall. New quarter-turn stops if the old ones are tired, swapped with the water off at the house main, and the drywall the new cabinet won't cover patched, textured and left to dry.
6. Set and fasten. The cabinet leveled off the high point of the floor, scribed to the wall and screwed into the studs, with the back cut for the stubs.
7. Top, faucet and drain. Faucet and drain mounted on the top, the top set, the trap and supply lines connected, the water run and every joint checked.
8. Finish. Caulk at the wall and backsplash, the light or outlet swapped if it's part of the job, the old vanity hauled away and the room cleaned.

What Do Homeowners Ask Before a Vanity Install?

With the Water Off and the Old Vanity Out, What Else Fits the Visit?

A vanity swap shuts the water off, opens the wall behind the cabinet and puts carpentry and plumbing in one small room for a day, or two if the wall needs patching. Work planned into that visit before it starts commonly comes in 25 to 50 percent below what the same work costs as a separate trip, because the setup, the protection and the shutoff are already paid for.

• The toilet. The water is already off and the floor is already protected, so a new toilet is a short add. See the toilet rows above and our bathroom remodeling page.
• The light over the mirror. Swap the old bar light for something sized to the new vanity while the wall is getting paint anyway. See light fixture installation.
• A GFCI or a moved outlet. A wider vanity can land right where the old receptacle sat. See electrical work.
• The mirror or a medicine cabinet. Hung level and anchored, surface-mounted or recessed between the studs. See handyman and installation work.
• Paint the room. The new cabinet changes the wall that shows. See interior painting.
• The floor, in the right order. A cabinet with a different footprint can expose a strip of floor the old one covered. Tile or a glue-down floor goes in before the vanity. Floating plank goes in after and stops at the cabinet with its expansion gap, because plank makers don't allow cabinets on top of a floating floor. See flooring installation.
• The shower that weeps. If grout or caulk in the shower next door has been letting water through, it gets a look on the same visit. See shower pan rebuild and leak repair.

If the vanity is the first step of a bigger bathroom, converting a tub to a walk-in shower and the Phoenix bathroom remodel cost guide are the next two reads.
