A bath tub faucet repair kit is usually the fastest way to stop a dripping tub spout, a stiff handle or water that suddenly runs cold in the shower. Most leaks in tub faucets trace back to a small set of worn parts: a cartridge, a set of seats and springs, O-rings, or a stem and washer on older compression valves. The right kit contains the exact parts for your faucet’s valve type, and that matters more than the number of pieces in the box. This list compares six kits by fit, included parts, and the patterns owners tend to report, so you can narrow your search before you buy. Selection criteria here were based on manufacturer specifications, brand reputation and common owner feedback, not on any hands-on testing.

Delta RP46655 Tub and Shower Cartridge Kit
This suits homeowners who have identified a Delta single-handle tub and shower valve and want a single part that replaces the moving internals. Because cartridges are brand and model specific, this is the choice when you can confirm the valve is a Delta.
Key specs
- Single-handle cartridge replacement for compatible Delta tub and shower valves
- Replaces the mixing element that controls temperature and flow
- Sold as a cartridge rather than loose seals
Pros
- Replaces the most common failure point in one part
- Brand-matched fit reduces guesswork
- Straightforward swap in most single-handle bodies
Cons
- Only useful if the valve is confirmed Delta and the model matches
- Does not address problems with the tub spout diverter
Moen 1225 Cartridge
This is aimed at owners of Moen single-handle tub and shower valves who have a leak or a handle that is hard to turn. Moen cartridges are widely referenced in replacement guides, which makes model identification easier.
Key specs
- Single-handle cartridge for compatible Moen tub and shower valves
- Controls hot and cold mixing and flow in one unit
- Identified by model number stamped on the valve or listed in Moen documentation
Pros
- Common part number that is easy to cross-reference
- Restores smooth handle operation in many cases
- Fits the most common Moen single-handle layout
Cons
- Older Moen valves may use a different cartridge; confirm before ordering
- Does not include a new handle or escutcheon
Pfister Tub and Shower Cartridge Kit
This is for owners who have a Pfister tub or shower valve with a dripping spout or inconsistent temperature. Pfister valves often use their own cartridge design, so a matched kit reduces the risk of a bad fit.
Key specs
- Cartridge replacement for compatible Pfister single-handle tub and shower valves
- Controls temperature and water volume
- Confirm compatibility by valve body and model before purchase
Pros
- Brand-matched part avoids mismatched internals
- Addresses the most common cause of drips in single-handle Pfister valves
- Simple to install with basic hand tools
Cons
- Limited usefulness if the valve is not a Pfister
- Owners sometimes report needing to match the cartridge height carefully
Danco Universal Tub and Shower Faucet Repair Kit
This is a practical pick for DIYers who cannot identify the brand of their tub valve, or who own an older faucet from a manufacturer no longer producing parts. A multi-brand kit spreads the odds of a usable seal or washer.
Key specs
- Multi-brand assortment of washers, seals and adapter parts
- Intended for compression-style tub and shower valves
- Includes replacements for common wear points such as washers and O-rings
Pros
- Useful when the faucet brand is unknown
- Covers several common wear parts in one purchase
- Good for a first repair on an older valve
Cons
- Universal parts may not seal as well as brand-specific parts
- Requires you to identify which piece you need, which can take trial and error
Kohler Tub and Shower Valve Repair Kit
This suits owners of Kohler tub and shower valves who want genuine internal parts. Kohler valves use brand-specific seals and components, so the manufacturer’s kit is the safest route for an exact fit.
Key specs
- Brand-specific internal seals and parts for Kohler tub and shower valves
- Designed around Kohler valve bodies; check the model number first
- Includes components that wear with mineral buildup and age
Pros
- Exact fit for Kohler valves reduces guesswork
- Addresses multiple wear points at once
- Manufacturer-matched components are a reliable starting point
Cons
- Only relevant for Kohler valves
- Repairs can be more involved than a single cartridge swap
Danco Two-Handle Tub Faucet Repair Kit
This is for owners of older two-handle compression tub faucets, where the usual leak source is a worn washer, seat or stem. It is a traditional repair approach rather than a cartridge swap.
Key specs
- Stem, washer and seat replacement set for two-handle compression valves
- Designed for compression-style tub faucets rather than cartridges
- Requires removing the stem to access the washer and seat
Pros
- Inexpensive way to fix a drip in a compression faucet
- Keeps the original handles and body in place
- Covers the main wear items in one set
Cons
- Not compatible with cartridge or ball-type valves
- Seats can be hard to remove on corroded valves, and owners sometimes report needing a seat wrench
Buying Guide
Choosing a bath tub faucet repair kit comes down to identifying your valve type, then matching the kit to it. A kit that fits the wrong valve wastes time and can leave you with a second leak.
Start With Your Valve Type
Most tub faucets fall into one of four categories: compression (separate hot and cold handles with rubber washers), cartridge (a single removable cylinder), ball (a rotating ball with spring-loaded seats), or ceramic disc. Remove a handle and look at the valve body. A single round cartridge points to a cartridge kit. Two stems with washers at the bottom point to compression. Identifying the type first narrows the list immediately.
Identify the Brand and Model
Look for a brand name on the valve body, the handle or the escutcheon plate. Model numbers are often stamped on the valve or printed on the packaging of the original faucet. Manufacturer parts diagrams and their replacement parts pages are the most reliable way to confirm a part number. If you have a Moen, Delta, Pfister or Kohler valve, the brand-matched kits above are the most direct route.
Specs to Check Before Buying
- Valve type: compression, cartridge, ball or ceramic disc
- Brand and model number, matched to the valve body
- Single-handle or two-handle configuration
- Whether the kit includes the cartridge or only seals and washers
- Whether the kit includes a handle, escutcheon or spout diverter, which is often sold separately
Choosing by Need
- Known brand, single handle: a brand-matched cartridge kit is usually the quickest fix.
- Unknown brand or older valve: a universal kit gives you a range of common washers and seals.
- Older two-handle compression faucet: a washer and seat set addresses the usual drip source.
- Leak from the spout only: the diverter or spout seals may be the problem rather than the valve.
Things to Watch Out For
Turn off the water supply before disassembly, and close the main if the shutoff valves are unreliable. Mineral buildup can seize screws and seats, so penetrating oil and a seat wrench may be needed. Replacing only one part on a worn valve can leave other seals to fail soon after. If the valve body is cracked or corroded, a kit will not solve the problem, and replacing the valve is the better path. For plumbing work involving gas, electrical hazards or any uncertainty about shutoff or water pressure, consult a licensed plumber.

FAQ
How do I know if I need a cartridge kit or a washer kit?
Remove the handle and look at the valve. A single cylinder that pulls out as one piece is a cartridge. Two separate stems with rubber washers at the bottom indicate a compression valve, which needs a washer and seat set.
Can one repair kit fit every tub faucet?
No. Cartridges, ball valves and compression valves each require different parts, and even within one type, brands use different dimensions. A universal kit can help with some older valves, but brand-matched parts are the safer choice when you can identify the model.
Why does my tub faucet still drip after replacing the cartridge?
Common causes include a worn spout diverter, a damaged seat or O-ring in the valve body, or a cartridge that was not fully seated. Check that the cartridge is installed in the correct orientation and that the retaining clip is secure.
Do I need to shut off the whole house water?
Shutting off the water supply to the tub is usually enough, if the valves are working. If the shutoff valves leak or do not close fully, turn off the main supply before you start.
What tools do I need for a typical tub faucet repair?
Most repairs need a screwdriver set, an adjustable wrench, a seat wrench or socket for compression valves, plumber’s grease, and a rag to protect the finish. A small tub of penetrating oil helps with stuck parts.
How long does a tub faucet repair take?
A cartridge swap on a known valve often takes under an hour once the water is off. Compression repairs can take longer, especially if seats are corroded or the stem is stuck.
When should I call a plumber instead?
Call a licensed plumber if the valve body is cracked, if the faucet is behind a wall that requires opening drywall, if the water supply shutoffs fail, or if you are unsure about any part of the repair. Structural or water-damage concerns should be assessed by a professional.
Conclusion
For a known Delta, Moen, Pfister or Kohler single-handle tub valve, a brand-matched cartridge kit is the most direct fix. For an unknown brand or older valve, a universal kit gives you a practical range of parts to try. Owners of older two-handle compression faucets will usually need a washer and seat set. Identify your valve type and model first, check what each kit includes, and confirm compatibility before ordering. When the valve body itself is damaged, a kit will not be enough, and a plumber can advise on replacement.
