Bathroom Sink Faucet Drip Repair: 5 Best Kits for Every Fix (2026)

Updated November 2026

A dripping bathroom sink faucet wastes water and keeps you up at night, and in most cases the fix is a worn washer, cartridge, O-ring or valve seat rather than a new faucet. The challenge is that a bathroom sink faucet drip repair only works if you buy the right parts for your brand and handle style. The picks below were chosen by checking manufacturer specifications, brand reputation for compatible replacement parts, and the patterns owners commonly describe in their feedback: whether the kit matches a named faucet family, how many parts it includes, and whether it covers the usual failure points.

Home Impressions Washerless Cartridge Faucet Repair Kit

Best for: Best overall for washerless cartridge faucets

This kit suits homeowners whose single-handle bathroom faucet has no traditional rubber washers and whose drip seems to come from the handle area or spout. Cartridge faucets are common in bathrooms, and a cartridge failure is one of the most frequent causes of a steady drip that persists even when the handle is fully closed.

Key specs

• Designed as a washerless cartridge faucet repair kit
• Intended for cartridge-style replacement rather than stem-and-washer repair

Pros

• Targets the cartridge, which is the usual culprit in washerless designs
• Avoids the guesswork of disassembling a stem to find the failed part
• Useful for a single-handle bathroom faucet with no visible washer

Cons

• Works only if your faucet is truly a cartridge design, so identify the type first
• Brand-specific fit varies, so check the model number against your faucet

Bottom line: Choose this if you have a washerless single-handle faucet and want the most likely fix for a drip in one part.

JTFS-10P Faucet Stem Assembly Replacement Kit for Delta Two-Handle Faucets

Best for: Best for Delta two-handle faucets

This is aimed at owners of older two-handle bathroom faucets who have found that a stem is leaking or that the seats and springs have worn. Stem-type faucets drip when the rubber seat or spring no longer seals against the valve, and replacing these small parts is often cheaper than swapping the whole faucet.

Key specs

• Listed as a 10-pack of faucet stem assembly replacement parts
• Includes seats and springs, per the listing name

Pros

• Multiple stems and seats in one package gives spares for each handle
• Covers the seat and spring, two of the most common drip sources in stem faucets
• Useful when the old stems are unbranded or hard to identify

Cons

• Sizing must match the stem type exactly, so measure or photograph the old parts first
• Owners sometimes need to buy a separate seat wrench or puller for removal

Bottom line: A good pick if you have a two-handle stem faucet and want spare parts on hand for the whole valve.

Buying Guide

Identify your faucet type first

Bathroom faucets generally fall into compression (stem with washers), cartridge (single or dual), ball, and ceramic disc designs. The drip source differs by type: stems leak at the washer and seat, cartridges leak at the cartridge body. Remove a handle and look at the valve before buying anything, and note the brand and model number if you can find them.

Match the brand and model

Replacement parts are not interchangeable across brands. Compare the model number on the faucet, or on the manufacturer’s website, with the kit listing before you order. A kit labeled for a family of faucets is safer than a generic assortment when you know the brand.

Count the included parts

Kits differ in how many spares they contain. A stem kit that includes seats, springs and O-rings covers more failure points than a single cartridge. Multi-part kits are useful when you do not know which component has failed, though they cost more time to sort through.

Check the size and fit

Washers and O-rings come in specific diameters and thicknesses. Measure the old part with calipers if you have them, or bring it to the store for comparison. A washer that is slightly too large will not seal, and one that is too small may squeeze out under pressure.

Consider the material

Brass valve components resist corrosion better than many plastics, and rubber parts vary in hardness and durability. Hard water accelerates wear on seats and washers, so choose parts rated for water use and replace them with matching materials.

Plan for the repair, not just the part

Turn off the water supply under the sink before starting, and plug the drain so small parts do not fall in. Some valves need a seat wrench or cartridge puller. If the valve body is corroded or cracked, a new part will not stop the leak, and replacing the faucet may be the better route.

Use a basic step-by-step approach

Before you buy, read a beginner walkthrough so you know what to expect. Our guide on repairing a dripping bathroom faucet covers the common sequence. If your faucet has a pop-up drain, you may also need guidance on the stopper, covered in our article on bathroom faucet stopper repair.

FAQ

How do I know if my bathroom sink faucet drip is from the washer or the cartridge?

A stem faucet drips at the spout when the handle is closed, and the leak often comes from a worn washer or seat. A cartridge faucet may drip from the spout or the handle base, and a failed cartridge often causes a steady drip that does not stop with the handle fully closed. Removing the handle and inspecting the valve is the most reliable check.

Do I need to turn off the water before repairing a dripping faucet?

Yes. Shut off the supply valves under the sink, then open the faucet briefly to release residual pressure. This prevents water from spraying as you disassemble the valve.

Can I use a universal repair kit for any faucet?

A generic assortment can cover many compression faucets, but it will not match every brand or cartridge design. Brand-specific kits reduce the risk of buying parts that do not seal.

How long does a bathroom faucet repair usually take?

For a simple washer or cartridge swap on a faucet you can reach easily, many homeowners finish in under an hour. Corroded parts, hard-to-reach valves or unfamiliar designs can take much longer.

Why does my faucet still drip after I replaced the washer?

The valve seat may be pitted or worn, so a new washer cannot seal against it. Mineral buildup or a damaged cartridge body can also cause a continued drip. Inspect the seat and clean out debris before reassembling.

When should I call a plumber instead of repairing the faucet myself?

If you smell gas, see water damage in the cabinet, or cannot shut off the supply valves, call a licensed plumber. If the valve body is cracked or the supply lines are corroded, a professional can assess the risk and recommend safe repairs. Consult a licensed plumber for any work involving water supply lines or water heater connections.

Are repair kits worth it compared to replacing the whole faucet?

For an older faucet in good condition, a repair kit is usually the more economical option. If the faucet is corroded, leaking from multiple points or no longer available in parts, a replacement may be the better long-term choice.

Conclusion

A bathroom sink faucet drip repair is usually a matter of identifying the failed part and matching it correctly. For most single-handle washerless faucets, the Home Impressions Washerless Cartridge Faucet Repair Kit is the most direct starting point. Delta two-handle owners should look at the JTFS-10P stem kit, while Delta single-handle owners with a confirmed cartridge leak will want the Danco 86970. Price Pfister two-handle owners have a matched option in the 88711 kit, and the 58 PCS assortment suits those who want a broad stock of common washers. Confirm your faucet brand and model before ordering, and replace worn seats along with the washer for the most reliable result.
