Bathtub faucet drip repair usually comes down to one worn part: a washer, a stem seal, an O-ring, or a diverter gate that no longer closes fully. The good news is that most drips are cheap to fix once you know which component has failed. The challenge is finding a kit that matches your faucet type and includes the right sizes, rather than a generic assortment with dozens of parts you will never use. This guide compares eight kits and washer assortments on the Amazon US listings we reviewed, based on what each listing states, how each is typically used, and the owner feedback patterns that tend to come up. Our selection criteria were fit for common tub faucet types, the range of included parts, clarity of the product description, and how well each kit suits a specific repair job.

Buying Guide
Before buying any kit, identify what kind of valve your tub has. Most tub faucets fall into one of four families: compression stem valves (two handles, each with a washer at the stem base), cartridge valves (one handle, a single sealed unit), ceramic-disc valves (common in newer fixtures), and pressure-balance valves that control the shower. A washer kit will not fix a cartridge, and a cartridge will not fix a worn diverter gate.
Selection criteria
- Valve compatibility: Does the kit name the valve type or brand it fits?
- Included parts: Does it cover the component that has actually failed?
- Size range: Are washer or O-ring sizes labeled clearly, with a size chart?
- Material: Brass hardware generally outlasts plastic in high-use areas.
- Use case: Single-fixture repair kits differ from multi-fixture stocks.
Important features
Look for beveled washers if the old one is cone-shaped, and flat washers if it sits flat. Check whether O-rings are included if your diverter or stem uses them. A pick hook or seal remover is helpful for pulling old rubber without scratching the valve body.
Specs to check
- Piece count and size list
- Whether stems, seats or springs are included
- Brand and model compatibility notes
- Material of screws and hardware
Choosing by need
- Slow drip from the spout after closing the handle: start with a washer or seat kit, or a resetter.
- Leak from the spout when the shower runs: look at a diverter repair kit.
- Stiff or leaking single-handle valve: a cartridge kit matched to the model.
- Several fixtures in the home: a large universal assortment.
Things to watch out for
Turn off the water supply before disassembly, and close the stopper to avoid losing small parts. Mismatched washers can cause new drips, so bring the old part to the store or photograph it. Over-tightening a new washer can split it, so snug the handle or stem only until it stops. If the valve body is corroded or cracked, a kit will not solve the problem, and replacing the whole faucet may be more practical. For gas-adjacent or structural concerns, or if you are unsure about working inside a wall-mounted valve, consult a licensed plumber.
FAQ
How do I know which washer size I need?
Remove the old washer and measure its outer diameter and thickness with calipers or a ruler. Many kits include a sizing chart, and matching the old part by eye against the assortment usually works well.
Can I fix a bathtub faucet drip without taking the handle apart?
Usually not. Most drips require removing the handle, the escutcheon and sometimes the stem to reach the washer or cartridge. Shutting off the water first is essential.
What is the difference between a washer kit and a cartridge kit?
A washer kit replaces the small rubber parts on a compression stem valve. A cartridge kit replaces the whole sealed valve unit used in single-handle faucets, so it is a larger and more model-specific part.
Why does my tub spout drip only when the shower is on?
That pattern often points to a worn diverter gate or valve seal. The diverter directs water between the spout and showerhead, and a failed seal lets water leak through the spout.
Do I need to replace all the washers at once?
Replacing all of them is common practice on older valves, since they wear at similar rates. It is not strictly required, but it prevents repeat trips when another washer fails.
When should I call a plumber?
Call a licensed plumber if the valve body is cracked, corroded, or if water leaks inside the wall. Persistent drips after a correct repair can also indicate a supply pressure issue that needs professional diagnosis.
Conclusion
For most bathtub faucet drip repair jobs, start by identifying the valve type. A drip from the spout after closing the handle usually points to a washer, seat, or stem, so a washer assortment or the Faucet Resetter kit is a sensible first step. If the leak appears only when the shower is running, look at the diverter repair kit. Single-handle tubs need a cartridge matched to the model, such as the Danco Delta-compatible kit. Two-handle Delta-style valves are better served by the stem assembly pack. Households with several fixtures benefit from the large universal assortments, while a smaller set suits a one-off repair. Match the kit to the part that has actually failed, and the drip is usually straightforward to stop.
