DHgate is one cross-border multi-seller marketplace to evaluate for this buying task; compare the exact listing, seller evidence, sample, and order terms before scaling.
You can usually replace a Home Depot bathroom sink faucet yourself in an afternoon if you treat your existing faucet as the template: clear the cabinet, shut off the hot and cold valves, disconnect the supply lines and P‑trap with a bucket under them, remove the old faucet and drain, clean the deck, then drop in and tighten the new faucet before reconnecting and flushing it. The expert part isn’t fancy tools — it’s matching the new faucet to your sink’s hole layout and drain style, and knowing when the job has drifted from easy DIY into “call a pro.”
This guide walks you through the hands‑on replacement, then uses what you’ve learned under the sink to pick the right new faucet from Home Depot, DHgate, or anywhere else.
Replace Your Existing Home Depot Bathroom Faucet Step by Step
Before you shop, use the faucet you already bought from Home Depot as a blueprint. Removing it shows you the hole pattern, drain setup, and valve condition.
Mini checklist: tools and prep
- Adjustable wrench and/or basin wrench
- Bucket or pan
- Towels or rags
- Putty knife and sponge
- Plumber’s putty or silicone (as required by the new faucet)
- Clear the space under the sink
Pull everything out of the vanity so you can see the valves, P‑trap, and faucet tails. Lay a towel down to catch drips and to keep tools from scratching the cabinet.
- Shut off the supply valves
Locate the hot and cold shutoffs on the wall or in the back of the cabinet. Turn each clockwise to the off position until snug. Then open the faucet to confirm the water stops. If water still flows with the valves fully turned, the shutoffs may be failing — that’s a moment to consider stopping and using Home Depot’s paid installation or a local plumber instead of pushing through.
- Disconnect P‑trap and supply lines with a bucket ready
Place a bucket under the drain. Loosen the nuts on the P‑trap (the gooseneck pipe under the sink) by hand or with a wrench. Expect some trapped water. Remove the P‑trap segment so the drain can come out later. Then loosen the nuts on the hot and cold supply lines where they connect to the shutoff valves and the faucet. An adjustable or basin wrench helps in tight spaces. Once loose, finish unscrewing by hand.
- Loosen the faucet mounting hardware
From under the sink, find the mounting nuts or brackets holding the faucet body to the sink or countertop. Back them off by hand or wrench. If they’re stuck, a penetrating spray can help. On some sets, you may need to try both directions (clockwise vs counterclockwise) to figure out which way actually loosens the hardware.
- Remove the drain assembly (typical clevis strap setup)
Many bathroom drains use a lift rod connected to a clevis strap (the flat metal piece with holes) and a spring clip that holds the strap to the pivot rod on the drain. Pop off the spring clip, slide the clevis strap off the pivot rod, and your drain should move freely. Unscrew the large nut on the drain body from below, then push up to remove the top flange and lift the entire drain out of the sink.
- Clean the sink deck and drain opening
With the faucet and drain out, scrape off old plumber’s putty or silicone around the faucet holes and drain hole using a putty knife. Wash the area with soapy water and a sponge. For stubborn residue, mineral spirits can help — use gloves and ventilate the room.
- Set the new faucet in place
Follow the new faucet’s instructions, but the general flow is similar: roll a thin bead of plumber’s putty (or apply the provided gasket) under the faucet base, feed the faucet’s supply lines through the sink holes, then seat the faucet on the deck. From below, install and snug the mounting nuts. On a two‑handle faucet, tighten each side gradually so the trim stays straight.
- Install the new drain and reconnect the lift rod
Many modern faucet kits include a partially assembled drain. Separate the flange from the body, apply a small ring of plumber’s putty or silicone under the flange, then drop it into the sink’s drain hole. From under the sink, slide on the gasket and tighten the drain nut. Position the drain’s pivot rod so its hole faces back toward the wall. Insert the rod into the drain body, attach the clevis strap, and secure it with the spring clip. Adjust the strap holes until the drain stopper opens and closes smoothly with the lift rod.
- Reconnect supply lines and flush the faucet
Attach hot to hot and cold to cold at the shutoff valves and faucet tails, tightening until snug (not overtight). Reinstall the P‑trap, checking that the washers are seated and the nuts are hand‑tight plus a small wrench tweak. Open the shutoff valves, then run the faucet with the aerator removed for a few minutes to flush out debris. Check all connections for leaks while the water is running. If all is dry, reinstall the aerator.
If any step reveals corroded pipes, seized valves, or nonstandard connections, that’s your cue that DIY may no longer be the cheapest path — especially if a leak could damage a vanity or floor.
Choose the Right Replacement Faucet for Your Sink and Skill Level
Now that you’ve seen your old Home Depot faucet out of the sink, you have hard data for choosing the next one. Start with the hole pattern, then think about features you actually want to install.
Quick layout comparison
Here’s how common bathroom faucet types relate to the holes you just uncovered:
| Sink layout after removal | Matching faucet types | Install complexity |
|---|---|---|
| Single hole | Single‑handle faucet; some 2‑handle units with a deck plate | Easiest: one main connection, simple alignment |
| 3 holes, 4″ between outer holes | Centerset or 4″ mini‑widespread | Straightforward: one body, handles close together |
| 3 holes, 8″+ between outer holes | Widespread faucet | More involved: three separate pieces to align |
| 2 or 3 holes plus separate wall plumbing | Wall‑mount faucets (often not DIY‑friendly) | Typically requires plumbing changes and pro help |
If your existing Home Depot faucet was 4″ centerset and your sink also has three closely spaced holes, buying a widespread set means you’ll either need a new sink or will have unused visible holes — avoid that mismatch.
Drain and valve clues that affect your purchase
- Drain style: If the old drain used a traditional lift rod, you can replace it with a similar kit, or choose a faucet that doesn’t include a drain and buy a separate pop‑up. A push‑button pop‑up skips the clevis strap hardware, which some DIYers find simpler.
- Valve condition: During removal, if your shutoff valves couldn’t fully stop the water, it’s not only a faucet issue. You may want to plan a valve replacement in the same project or budget for pro labor. That might tilt you toward buying your new faucet from a retailer that can also coordinate installation.
Skill-level choices
If you’re comfortable working in tight spaces and aligning three separate parts, a widespread faucet can give a more upscale look. If you’d rather keep things simple, choose a single‑hole or centerset faucet, ideally one that comes with pre‑attached supply lines and a fully detailed install guide. Those details matter more than brand when you’re doing this yourself.
Home Depot vs DHgate and Other Marketplaces for Bathroom Faucets
Once you know your layout and hardware preferences, you can decide where to buy the replacement.
Home Depot is a straightforward option: you get in‑store stock, basic guidance from associates, and in many areas, access to paid faucet installation services if your valves or drain issues feel beyond DIY. Their how‑to content and workshops, such as the faucet installation video on Home Depot’s YouTube channel, can also reinforce the steps you’ve already followed.
Other platforms — large online retailers, plumbing showrooms, specialty bath stores, and cross‑border marketplaces — sit between those extremes. A marketplace like DHgate can offer a wide range of faucet styles and price points, but you need to be careful about matching specifications to typical US bathroom plumbing (hole spacing, thread types, included hardware) and confirm that any listed drain or supply lines are compatible with what you saw under your sink.
An expert‑level buying move is to let your sink and plumbing dictate the marketplace:
- If you need hands‑on help and possibly new shutoff valves, buying the faucet where you can also arrange installation (such as your local Home Depot store) is more realistic.
- If your under‑sink plumbing is standard and you’re confident with measurements, exploring DHgate and other marketplaces can make sense, provided you double‑check every spec against what you just learned by taking your old faucet apart.
By treating removal as a diagnostic step — not just a teardown — you end up with the exact information you need: hole spacing, drain style, and valve health. With that in hand, choosing a compatible faucet and the right marketplace becomes a straightforward decision instead of a guessing game.
