Quick answer
Home Depot lists $195 average installation, with a $97–$369 range, excluding your faucet. Moen’s manual Adler suits compatible kitchen sinks; bathroom sinks need a different fit. Ask for a quote covering shutoffs and removal.
Parts and a tool for different jobs
These are conditional choices, not a shopping list for every replacement. The Adler is a kitchen faucet. The connector needs matching endpoints; the wrench needs a matching nut. Check the included hardware before adding either.

Separate the faucet from its installation
A faucet replacement quote needs a clear starting point: an existing sink, an identified replacement and a written list of included work. A quote for moving pipes is a different project from mounting a faucet in the same location.
Home Depot’s installation benchmark, re-read October 22, 2026, describes its own service. Use it as a scope reference, not a promised local price. Confirm whether the figure you receive is installation only or a total that already includes the faucet.
For the same retailer benchmark, new supply lines and old-faucet disposal are included; countertop drilling and cabinet modifications are excluded. Other installers may define the job differently. Ask for their written scope before comparing totals.
Moen Adler 87233SRS for a kitchen sink
A faucet, a connector and a wrench do different jobs, so none of them is scored. Your sink and your quote decide which ones you need. All three were new and in stock on Oct 22, 2026, 12:35 PM EDT.
Moen’s Adler 87233SRS is the manual kitchen example here. The useful cost question is whether it fits your existing sink without countertop or cabinet alterations. Its finish name identifies the exact offer; it does not tell you what a plumber will charge to remove your old faucet.
The 87233 series drawing allows one or three mounting holes and specifies a minimum hole diameter of 1-1/2 inches. Measure the actual opening and check the drawing before booking installation. A decorative plate can cover unused openings, but it cannot make an undersized center hole accept the faucet body.
Moen limits the mounting deck to 2-1/2 inches. Compare that limit with the material the mounting assembly must pass through. A photograph of the underside helps the installer see reinforcement or restricted access. Ask how an unexpected mounting obstruction will be handled before the old faucet comes out.
Where it does well
- One or three mounting holes, per Moen’s series drawing
- 3/8 inch compression supply connections
- Mounting thickness up to 2-1/2 inches
What to watch
- Kitchen mounting does not establish bathroom fit
- Check clearance for the pulldown hose
- Supply extensions require a separate connection check
The specified supply connections are 3/8 inch compression. That is a connection description, not proof that every loose braided hose will extend them. Have the installer check the faucet ends, valve outlets and available reach. Add a connector only after both mating connections and the required route are identified.
Check the pulldown hose route inside the cabinet as well as the visible spout above it. Ask the installer to show that the hose moves freely after the supply connections are made. A shelf, stored cleaning bottle or drain assembly should not be ignored when you describe the available space.
My call: choose this Adler when the existing kitchen mounting fits its drawing and the written quote covers the whole replacement. Keep the faucet purchase separate from the installation amount. For a bathroom sink, select a faucet that matches that sink’s own hole pattern rather than adapting this kitchen example.
Fluidmaster B6F20 for a longer supply run
Fluidmaster’s B6F20 is an optional connection part, not a required companion to the Adler above. Its catalog identifies a 20 inch faucet connector with 3/8 inch compression at both ends. The exact Amazon offer specifies female compression ends and braided stainless steel. Those endpoint details decide whether it belongs in your job.
Two female connector nuts need suitable male mating connections. Reading 3/8 inch on the faucet sheet and 3/8 inch on a hose title is not enough to establish a usable extension. Ask the installer to identify the actual mating surfaces before adding this line to the parts list or the quote.
That check matters when a replacement faucet has its own supply tubes. If those tubes already reach compatible valves, a separate connector may have no role. If they stop short, the solution still depends on the maker’s instructions and connection arrangement. Do not assume an extra hose will join directly to another female nut.
Where it does well
- 20 inch connector in Fluidmaster’s catalog
- 3/8 compression at both ends
- Exact B6F20 model named in the API offer
What to watch
- Both ends are female; it does not join two female nuts
- Not a universal extension for integrated faucet supplies
- No need to add it when the existing quote includes the correct lines
Length is the next check. The B6F20 is 20 inches, so compare it with the route between the identified endpoints. Ask the installer to account for bends and clearance around the drain. Buying by the straight gap alone leaves the hose route unresolved and does not establish compatibility.
For a plumber installation, first ask whether new supply connectors are already included. If they are, specify the type and any exception for extensions. Buying another B6F20 in advance should follow a confirmed need. A written parts list also makes it clear who checks the connector and who addresses a leak after installation.
My call: include B6F20 only when its ends and route match a documented connection plan. It is useful to name the part precisely, but it cannot repair a failed shutoff or an incompatible faucet mounting. Leave those separate tasks in the quote rather than treating a new hose as the answer to every under-sink problem.
RIDGID 1017 basin wrench for tight nuts
RIDGID’s 31175 is model 1017, a telescoping basin wrench for restricted access around faucet fittings and retaining nuts. The maker lists a 10 to 17 inch adjustable shank and 3/8 to 1-1/4 inch capacity. Match the nut you need to turn, not the nominal water-pipe size printed on nearby plumbing.
The basin-wrench page describes spring-loaded jaws and a head that can hold positions through a right angle. That arrangement is relevant when a conventional wrench will not sit squarely under the sink. Inspect the working space before buying a tool: a photograph of the mounting area can help you identify the obstruction.
RIDGID sells several basin-wrench models together. Keep model 1017 separate from the LED-equipped 2017 and the larger-capacity 1019. Features shown at the top of a mixed product-family page do not automatically belong to every ordering row. The catalog number 31175 is the useful identifier for this offer.
Where it does well
- 10 to 17 inch telescoping shank
- 3/8 to 1-1/4 inch capacity
- Spring-loaded jaws and pivoting head, per RIDGID
What to watch
- Measure the nut rather than choosing by pipe size
- Do not transfer LED features from RIDGID’s 2017 model
- A wrench does not solve damaged piping or failed isolation
For a DIY cost comparison, count a basin wrench only if you need one and do not already have suitable access tools. Ask whether the replacement faucet includes its own installation tool. Buying a separate wrench before checking the supplied mounting hardware can add an item that your actual installation never uses.
Wear eye protection when using the basin wrench. Shut off the water before working on the faucet, as Moen directs. If the valves will not isolate the supply, stop and call a plumber before loosening connections. A longer wrench does not make pressurized disassembly safe or establish that a corroded fitting can tolerate more force.
My call: use the 1017 for a confirmed access problem within its capacity. If you are hiring a plumber, ask about difficult removal in the labor scope instead of buying their tools. Keep a damaged mounting assembly or pipe stub as a separately assessed problem, with authorization before additional work starts.

Does the quote cover your actual job?
Use this worksheet before approving a kitchen or bathroom faucet replacement. Put your measurements and the installer’s written scope beside each other. An unanswered line means the total still needs an explanation; it does not mean a particular surcharge applies.
| Check | Verified value or reader input | What the quote must specify | Route | Evidence |
|---|---|---|---|---|
| Mounting pattern | Your hole count and spacing | Exact faucet model and compatible drawing | Same opening or reassessment | Moen 87233 series drawing for Adler |
| Deck thickness | Adler limit: 2-1/2 inches; measure your deck | Any mounting restriction or approved solution | Fits drawing or reassessment | Moen 87233sp, page 1 |
| Supply connections | Your valve outlets, faucet ends and reach | Direct connection, connector or approved adaptation | Included item or named extra | Maker drawing and connection inspection |
| New supply lines | Check what the faucet includes | Which lines or extensions are included | Avoid duplicate parts | Home Depot service scope; exact faucet manual |
| Bathroom drain | Reuse existing drain or fit supplied assembly | Faucet-only work versus drain/trap work | Separate scope if needed | Installer’s written proposal |
| Countertop | Existing opening or proposed new hole | Fabricator scope and dust controls | Specialist assessment | Home Depot exclusions; OSHA 3768 |
| Shutoffs and piping | Do both valves isolate? Any visible damage? | Valve or piping work; permit responsibility | Plumber assessment | Moen removal caution; local authority |
| Removal and disposal | Old faucet and access photographs | Removal, disposal and any exclusion | Included or separately identified | Home Depot disposal FAQ; written quote |
For a bathroom faucet installation cost, first separate the faucet from any drain assembly included in the box. Ask whether the installer will reuse the drain or install the new one. A faucet-only proposal should not leave you guessing about the stopper, tailpiece or existing trap.
For two bathroom sinks, request a scope for each location. Matching faucet names do not establish matching shutoffs or access. Ask whether the proposal covers both replacements and which conditions would require approval for additional work. Do not divide one combined total into invented per-sink labor charges.
Write the total as: faucet purchase + installation quote + explicitly excluded work + applicable taxes or fees. Leave unknown amounts blank until confirmed. If the installation quote already includes a part, do not count that part a second time.
Compare scope before comparing totals
A customer-supplied faucet changes what you have already purchased, but it does not define the installation agreement. Send the exact model and under-sink photographs with your request. Ask each installer to price the same work and explain what happens if removal reveals a problem.
| Question for each installer | What a clear answer tells you | What remains unresolved without it |
|---|---|---|
| Is this installation only or a supplied-faucet total? | Whether the faucet purchase is already counted | A misleading comparison between different totals |
| Is the charge fixed or based on time? | What the quoted installation amount represents | Any minimum charge, travel or additional time policy |
| Does removal include difficult mounting hardware? | Which removal conditions are covered | How unexpected removal work is authorized |
| Are new lines and any adapters included? | The connector type and scope | Unspecified parts or incompatible extensions |
| What happens if a valve does not close? | Who assesses it and gets approval | Water isolation and separate repair scope |
| Who addresses product and installation problems? | Responsibility and written terms | Whether a return visit is included |
A kitchen faucet installation cost cannot be inferred from finish alone. A manual pulldown model needs a compatible mounting and hose route. A powered model adds its own power requirements. Ask about the exact model instead of assuming every kitchen faucet has the same installation scope.
Keep a concealed tub or shower valve out of a sink-faucet comparison. The visible trim may hide a different plumbing task. If the proposal involves opening a wall or moving a supply, request a description of that alteration rather than applying a sink replacement benchmark to it.
Check the sink before choosing the faucet
The existing opening is the starting point. Record the hole layout above the sink, mounting thickness below it and the route to both shutoffs. A photo with dimensions is more useful for a quote than a faucet finish name alone.
For the Adler example, compare one or three holes, the 1-1/2 inch minimum opening and the 2-1/2 inch deck limit with Moen’s drawing.
Match the separate centerset or widespread mounting drawing to the existing holes. A plate does not turn every bathroom layout into a compatible mounting.
Have the installer check valve outlet, faucet endpoint and reach together. Do not choose B6F20 just because two descriptions contain 3/8 inch.
Use a qualified fabricator’s assessment. OSHA identifies silica exposure from countertop work; the work needs dust controls and appropriate respiratory protection where required. Avoid casual dry drilling.
Give the installer an underside photograph that shows the faucet mount, drain and shutoff valves together. If the old faucet hides the opening, say that the diameter is unconfirmed. Keep the existing faucet connected until water isolation and the removal plan are settled.
For mounting thickness, use the dimension the maker actually labels in the drawing. Do not assume a countertop’s advertised thickness describes the entire mounting path. Where the drawing is unclear, have the installer resolve the fit before you commit to alteration or extra parts.
Check included parts before adding supplies
A new faucet can arrive with its own mounting hardware, supply tubes or drain components. The exact model’s manual decides how those parts join. Ask the installer to identify what is included in the box and what their quote adds.
| Part of the job | Check first | What to write in the scope |
|---|---|---|
| Supply connection | Faucet ends, valve outlets and reach | Included connections and any approved extension |
| Mounting plate and gasket | Hole layout and maker’s instructions | Which included mounting arrangement is used |
| Bathroom pop-up drain | Exact faucet package and sink arrangement | Reuse existing drain or install supplied assembly |
| Old faucet hardware | Access and visible condition | Normal removal and treatment of unexpected damage |
| Sealant | Exact joint and maker’s instruction | Specified product and application, if required |
Do not make plumber’s tape, putty or pipe dope a universal item on the parts list. Delta’s kitchen instructions prohibit sealant on specified supply connections, while its metal pop-up instructions specify sealant at different drain joints. Those are different joints on different assemblies. Follow the manual for the faucet and drain you actually install.
If that manual calls for silicone or another chemical, follow its label’s ventilation and protective-equipment instructions. If you cannot identify the joint or the required sealant, leave the assembly to a plumber. Adding sealant to an unidentified connection is not a substitute for checking how it seals.
Decide which work you can handle
For DIY, compare the parts and tools you actually need with a written installation quote. Include the possibility of professional help if a shutoff fails. Do not treat the retailer benchmark as guaranteed savings or assume a wrench purchase makes every replacement suitable for DIY.
Wear eye protection before using a wrench under the sink. RIDGID’s wrench safety guide calls for eye protection. Follow the faucet and tool instructions for the work you plan to do, and stop if you cannot isolate the water or reach the mounting hardware safely.
A direct replacement may be a DIY option if local rules allow it and you can follow the exact model’s manual. Moen says to turn water off before removal. Open the faucet to relieve pressure and verify isolation before disconnecting; call a plumber if flow continues.
Do not disconnect pressurized lines. Follow the maker’s shutoff precaution and call a licensed plumber if a valve fails to isolate. Plan the water-main shutoff with them before repair.
Keep water isolated before opening a connection. Let hot components cool and use the faucet maker’s safety instructions. If you cannot control the hot supply, stop and call a plumber.
Ask a plumber about pipe relocation and local permit rules. For new receptacles or circuit work, use a licensed electrician and have the circuit safely de-energized. Keep those tasks separate from a manual faucet swap.
Permit requirements depend on your location and the work. Do not assume that a direct faucet replacement and a shutoff or piping alteration receive the same treatment. Ask the local building department what applies, then have the installer identify who handles any required permit and inspection.
If you are hiring a plumber, discuss difficult access as part of their installation scope. You do not normally need to buy the installer’s basin wrench. For DIY, inspect the mounting hardware first and decide whether the supplied installation tool already handles it.
Agree on the completion checks
Put the final checks in the installation agreement. The exact manual controls flushing, connection assembly and startup. Ask for a demonstration of the completed faucet rather than assuming that a mounted body means the supply and drain work is finished.
| Check | What to ask the installer to demonstrate | Why it belongs in the scope |
|---|---|---|
| Supply connections | Inspect both connections after model-specific startup | A mounted faucet does not establish a dry connection |
| Hot and cold operation | Demonstrate normal handle operation safely | Confirms the intended controls work |
| Pulldown hose | Move it through normal travel without obstruction | Checks the under-sink route |
| Bathroom stopper | Operate any newly installed pop-up and inspect the drain | Separates faucet-only from drain work |
| Removal and cleanup | Confirm old-faucet disposal and agreed cleanup | Closes the quoted job rather than leaving an assumption |
Keep the model label and installation paperwork after the job. If a connection leaks, shut off the water and contact the installer rather than tightening parts at random. The manual and written scope help distinguish a product issue from a connection or drain issue.
Questions about faucet replacement costs
How much does installation cost if I already bought the faucet?
Ask for an installation-only quote for that exact model and sink. The faucet purchase is already your separate expense. Have the installer identify removal, connections and excluded repairs instead of treating a published service benchmark as your local labor quote.
Does the installation quote include the faucet?
Only if the written proposal says so. Record the model and who supplies it. A total that includes a faucet cannot be compared directly with a labor-only figure until you separate the scopes.
Why do quotes for two bathroom faucets differ?
Ask each installer whether both locations include drain work, new lines, removal and any valve repairs. Send photographs of each sink. Identical faucet models do not establish identical access or shutoff condition.
Does a kitchen faucet always cost more to install than a bathroom faucet?
The room name does not establish the work. A kitchen pulldown needs a clear hose route, while a bathroom proposal may include a separate pop-up drain. Compare the actual mounting and included tasks rather than assigning an unsupported room-based surcharge.
How long does replacing a faucet take?
Ask the installer for a job-specific time estimate based on the exact model, access and removal conditions. Send under-sink photos with your request. Ask how a failed valve or inaccessible mounting nut would change the schedule before work starts.
Can I replace a faucet myself?
A compatible direct replacement may be suitable if local rules allow it and you can follow the maker’s manual. Turn off the water before removal, relieve pressure and verify isolation. If flow continues or a shutoff leaks, stop and call a licensed plumber.
Does installation include old-faucet disposal?
Home Depot’s published service scope includes disposal. For another installer, ask for removal and disposal to appear in the proposal, with any exception or fee identified before work starts.
Do I need new supply lines?
Check the exact faucet package and the installer’s scope. Identify the faucet endpoints, valve outlets and reach. Integrated supplies that already reach suitable valves do not establish a need for the separate B6F20 connector shown above.
Do faucet connections need tape, putty or silicone?
Use the exact model’s instructions for each joint. Delta’s cited supply connection instructions prohibit sealant, while its metal pop-up procedure specifies sealant at particular drain joints. If chemicals are specified, follow the label’s ventilation and protective-equipment instructions.
What if my shutoff valve does not work?
Do not loosen a connection while water remains pressurized. Follow the maker’s shutoff precaution and have a plumber establish safe isolation and assess the valve. Ask for any valve repair and permit responsibility to be described separately before authorizing extra work.
How we check fit and cost figures
Why trust PlumbingPicks?
Isaac Daniels is a licensed journeyman plumber in Georgia. We check mounting dimensions and supply connections against maker documents. Before buying a replacement, compare those dimensions with your sink and ask the installer to resolve any mismatch in the written quote.
How we pick
We read Moen’s 87233 series drawing, Fluidmaster’s connector information and RIDGID’s model-specific ordering information. We chose three different job roles. None is scored, because a faucet, a connector and a wrench can’t share one fair formula. We re-read the Creators API offers on Oct 22, 2026, 12:35 PM EDT: all three were the genuine named models, new and in stock.
Home Depot’s service benchmark covers its own installation scope. Compare it with your written proposal, then add the faucet purchase only if it is excluded. Confirm any unknown amounts with your installer before approving the total.
On Oct 22, 2026, 12:35 PM EDT, CPSC’s recall search showed none for these items: Moen’s two recalls covered Flo battery back-ups and garbage disposals, RIDGID’s five covered nailers, wet/dry vacuums, table saws and stepladders, and Fluidmaster had none.
| Evidence | What it supports | Limit |
|---|---|---|
| Dated service guide | One provider’s installation benchmark and scope | Not a national dataset or local estimate |
| Maker drawing | Mounting dimensions and connection type | Reader measurements and exact manual still matter |
| Creators API offer | Named model, seller, condition and availability on the read date | Offers may change before purchase |
| Editorial quote worksheet | A way to compare defined work | No prediction of labor hours or unknown repairs |
