Your tub holds water when it should drain, or it won’t hold water when you want a soak — and the fix is almost always the drain kit, not the tub itself. The tricky part is that “bathtub drain kit” covers a wide spread of parts, from a simple stopper swap to a full waste-and-overflow assembly you cement into the pipes behind the wall. Get the wrong thread size or the wrong stopper style and you are making a second trip to the store. What separates a kit that lasts from one that gives up in a season is the metal in the trim and stopper, the exact thread size on the drain shoe, and whether the overflow plate lines up with the holes already drilled in your tub.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will find the common kit types explained in plain terms, the three specs that actually decide fit, and a shortlist of eight kits matched to real bathrooms. Match your thread size and stopper style to your tub before you buy, and a bathtub drain kit installs in an afternoon.
Our Picks at a Glance



How To Choose The Best Bath Tub Drain Kit
Three numbers and one style choice decide whether your kit fits on the first try: the thread size on the drain shoe, the overflow plate hole pattern, and the stopper style. Everything else — finish color, brand, price tier — is preference. Start by measuring, not shopping.
Measure the Drain Shoe Thread First
The drain shoe is the threaded fitting at the bottom of the tub where the stopper screws in. Most US tubs use a 1-3/8 inch or 1-1/2 inch NPSM thread — NPSM being the national straight pipe thread standard for this fitting. A kit that ships with a thread adapter bushing covers both sizes, which is why “universal fit” kits are so common. If your tub is older and you are unsure, pull the old stopper and hold a tape measure across the opening; a 1-1/2 inch shoe is the standard modern size, and a 1-3/8 inch shoe is usually found on older tubs.
Match the Overflow Plate to Your Tub
The overflow plate is the chrome or brushed plate on the tub wall above the drain — it hides the hole where the overflow pipe connects. Count the screw holes in your existing plate: a two-hole plate is the classic pattern, while some tubs use a single-hole slotted overflow. This is where most returns happen. A kit with a two-hole faceplate will not bolt onto a tub drilled for a slotted single-hole overflow without a separate conversion piece.
Pick the Stopper Style You Will Actually Use
Lift-and-turn and tip-toe stoppers let you close the drain by pressing or twisting the stopper itself — intuitive and handy for anyone with limited grip strength or small kids who cannot reach a chain. Push-n-lock is a simple press to close and press again to open, so there is nothing to twist. A foot lok stop, also called tip-toe, works the same way with a foot press. If you have long hair in the house, look for a kit with a hair-catching basket built into the drain so debris gets trapped before it reaches the trap.

In‑Depth Reviews
1. WELLUP Brushed Nickel Bathtub Tub Drain Conversion Kit
Our pick — over 4.5★ from 850+ verified ratings; the strongest balance of quality and price.
A complete brass-and-steel conversion kit with a thread adapter bushing that fits both 1-3/8 in. and 1-1/2 in. NPSM drains.
If your tub is older and you just want the stopper working again, the WELLUP conversion kit is the safest bet on this list. It comes with a thread adapter bushing (a small metal ring that converts between thread sizes) so the same kit threads into either a 1-3/8 inch or a 1-1/2 inch NPSM drain waste — NPSM being the straight pipe thread standard tub drains use. That one bushing is why it earns so many repeat recommendations: you do not have to guess which size your tub is before ordering. It ships as a complete set: the drain, the thread adapter bushing (1-1/2 in. NPSM x 1-3/8 in. NPSM), a washer, a two-hole overflow faceplate, and two 1/4 in.-20 UNC faceplate screws.
The stopper is a lift-and-turn, meaning you lift it up by hand and rotate it clockwise or counterclockwise to lock it open or closed. In practice, that means no chains, no flimsy plastic levers, and anyone in the house can operate it. The trim is solid brass and stainless steel, so the drain shoe does not flex when you torque it in and the brushed finish does not tarnish quickly in a wet bathroom. Owners install it in a five-minute window in many cases, and the recurring feedback in the review pages is that even a 1950s bathroom remodel has taken to it without drama. As owners put it: “Worked great. Finally found something that fit my very old bathtub.”
The main trade-off is the top cap. Some buyers report the stopper can loosen or detach from the twist mechanism if it is bumped hard — it reattaches simply, but it is a small part to handle with wet hands. The paint durability on the brushed finish also draws mixed feedback, with a handful of reports of chipping after a season or two in a heavy-use bathroom. Neither is a reason to skip it; both are gentle-use notes. If you want a kit that survives a very old tub and a tight install window, this is the one.
Where It Wins
- Fits both 1-3/8 inch and 1-1/2 inch NPSM drains with the included adapter bushing.
- Solid brass and stainless steel trim resists tarnishing in a wet bathroom.
- Lift-and-turn stopper is tool-free and easy for kids or older hands to use.
- Complete kit ships with drain, adapter, washer, two-hole faceplate, and screws.
What To Know
- The stopper cap can loosen from the twist mechanism if it is bumped hard, though it reattaches simply.
- Brushed finish paint durability draws mixed feedback after long-term use in high-traffic bathrooms.
- Not a full waste-and-overflow assembly — it replaces the stopper and trim, not the piping behind the wall.
Reach for this if: your tub’s stopper is worn out and you want a complete brass-and-steel replacement that threads into either standard drain size without a plumber.
Look elsewhere if: your overflow plate has a single-hole slotted pattern rather than the classic two-hole layout.
2. HIDROP Chrome Tub Drain Lift and Turn Assembly
A chrome-plated brass lift-and-turn stopper with a thread adapter bushing for 1-3/8 in. or 1-1/2 in. NPSM drains.
The HIDROP is the value pick for anyone replacing a chrome stopper in a standard tub. It ships with the same universal fit story as the WELLUP — a thread adapter bushing that fits 1-3/8 inch or 1-1/2 inch tub drain waste. The chrome-plated solid brass and stainless steel construction gives the drain shoe real heft, so when you spin it into the tub it does not deform the way a stamped-metal trim would. The lift-and-turn mechanism works the same way: lift by hand, rotate to lock open, rotate back to seal. Owners who have replaced cheap plastic versions note that the HIDROP stays closed under a full tub, which is the one thing a stopper has to do.
What stands out most in the reviews is the finish. Owners swapping out an older tub report that the chrome looks newer than the fixture it replaced, and one long-time contractor notes he uses it repeatedly on jobs. The included screws are a small mismatch point — some tubs have a slightly different overflow plate screw size — but on most installations the original screws can be reused without issue.
The durability story is the split. Several owners have had the finish hold up over months of daily use; a smaller set report the plating starting to wear or flake sooner than they expected. It is one of those kits that rewards picking the right finish color for your bathroom, since replacing it later is easier than refinishing it. If you want all-metal construction in a chrome finish and are comfortable doing a standard stopper swap, it is the smart money on this list.
The chrome factor: this is the pick to make when you want the finish to match an existing chrome faucet and shower trim, and you are fine buying an all-metal kit rather than the cheapest stamped-metal option on the shelf.
The honest caveat: it is not a long-life champion in every bathroom. For heavy-use rentals or a very wet tub, budget on replacing it sooner than a solid brass lift-and-turn kit would last, and save accordingly.
Pick it for: a clean chrome stopper swap in a standard-size tub where you want all-metal construction without paying premium prices.
Think twice if: your tub sees constant renters or daily deep soaks and you would rather buy once — the finish is the piece most likely to give out first.
3. DANCO Touch-Toe Tub and Bath Drain Kit
A touch-toe stopper kit with 1-1/2 in. plastic tubing and a two-hole faceplate, sized for tubs up to 15 in. deep.
The DANCO Touch-Toe kit is the pick for anyone who has a tub up to 15 inches deep and wants to skip the chain. The touch-toe stopper works by pressing the stopper body with a toe to close and pressing it again to open — no chain, no lever, no plastic flap. DANCO ships this as a complete kit with 1-1/2 inch plastic tubing and a two-hole faceplate, so it is built for tubs where you are replacing the whole existing drain assembly rather than just swapping the trim. The plastic tubing is a deliberate choice; it is lighter to handle and cheaper to ship than a brass waste assembly, and it uses slip joint washers for a leak-free seal that is adjustable during install.
What works well here is the reach. A common problem with cheaper kits is that they are too short for a mid-depth or deeper tub — one owner chasing a mid-depth tub with 11 inches from rim to drain found most kits landed too high. The DANCO fits the standard-size depth range and lands flush against the tub floor. Clawfoot tub owners also tend to like the look; the exposed chrome trim reads better against a vintage tub than a plastic stopper would. The touch-toe mechanism is a different feel than a lift-and-turn, and some owners need a bath or two to adjust to pressing rather than twisting.
The bits to know before you buy. The plastic tubing is not for everyone — if you want an all-metal waste-and-overflow assembly behind the wall, this is not that kit. A couple of owners have flagged that the overflow gasket’s flaps are narrow for a thick cast iron tub, and on a very old clawfoot the gasket can drop out during install. In both cases the fix is the same: plumber’s putty and a bit of patience. On a standard tub that takes a 1-1/2 inch drain, the install is straightforward and the work is quick.
Built For
- Fits standard tub depths up to 15 inches, including mid-depth tubs that reject shorter kits.
- Touch-toe stopper is intuitive — press to close, press to open — with no chain to tangle.
- White polypropylene tubing with slip joint washers seals for a leak-free, adjustable fit.
- Vintage-friendly chrome finish on a two-hole faceplate and stopper.
Trade-Offs To Weigh
- Plastic tubing rather than a brass waste assembly — fine for most tubs, not the pick for all-metal builds.
- Overflow gasket flaps can be too narrow for very thick cast iron tubs and may need plumber’s putty to stay put.
- Not compatible with single-hole slotted overflow faceplates — this is a two-hole kit.
Fits your job if: you have a mid-depth or clawfoot tub and want a toe-tap stopper with a full plastic-tubing assembly behind it.
Keep shopping if: you need an all-metal waste-and-overflow assembly behind the wall, or your tub has more than two overflow screw holes.
4. Citymoor Brushed Gold Bathtub Drain Kit and Overflow Faceplate
A brushed gold lift-and-turn kit with a hair filter basket inside the drain body and elbows for 1-3/8 in. and 1-1/2 in. tubs.
Hair is the reason most bathtub drains eventually clog, and the Citymoor kit solves that before it starts. Inside the drain body sits a hair filter structure that traps strands before they make it down the trap — in a house with more than one long-haired bather, that single detail turns a once-a-year drain snake into a rinse-and-go routine. The kit is compatible with most bathtubs and fits tub elbows for 1-3/8 inch and 1-1/2 inch, so it covers both common drain sizes. The lift-and-turn stopper is easy to operate — lift, turn, drain; turn back and lower to store water — and it is friendly enough for kids and older hands, which matters more than most people realize until they are balancing a foot on a wet tub floor.
The finish is the other selling point. Brushed gold is a tricky color to match — one owner doing a primary bathroom remodel had spent hours looking at varieties of gold before settling on this one because it read as a true brushed gold rather than a yellow or a rose tone. It sits comfortably in a bathroom with matte black, brass, or black-and-brass fixtures. The metal body is designed with a corrosion-resistant finish, so it should handle the humidity of a bathroom without spotting easily. Buyers replacing builder-grade chrome trim with something warmer tend to land here.
Honest note on the stopper action: the top can close a bit too easily if it gets bumped mid-shower, so water may start pooling when you do not intend it to. It is a small quirk — owners mostly shrug it off and would buy it again — but it is worth expecting. There is also a 30-day money-back guarantee and 3-month replacement policy on the product if issues do pop up. For a remodel where the finish is the star and you want a hair catcher built in, this is the one.
Why buyers pick it: the built-in hair filter is the quiet hero here — the built-in hair filter traps strands before they reach the trap, cutting how often you snake the drain.
Small quirk to know: the stopper can close if knocked, so if you share a tub with someone who props a foot on the drain, water may pool unexpectedly.
Right pick for: a brushed gold bathroom remodel where you also want a built-in hair catcher reducing how often you snake the drain.
Not for you if: a stopper that sometimes closes when bumped would bother you more than the hair filter is worth.
5. Moen T90331 Chrome Tub & Shower Drain Kit
An all-metal chrome trim and Push-N-Lock stopper for 1-1/2 in. NPSM drains, with the overflow cover included.
If you already have Moen trim on your tub, the T90331 is the piece to buy rather than gamble on a cheap aftermarket copy. It is an all-metal chrome drain trim with the Moen Push-N-Lock stopper — press to close, pull to drain — that replaces the drain trim on tubs with 1-1/2 inch NPSM threaded drains. It ships with the coordinating overflow cover, and the trim profile is approximately a half inch projecting from the tub surface, so it sits cleanly against the wall rather than standing proud. The Moen limited lifetime warranty is one of the real differentiators here; it is uncommon on a drain kit, and it reflects the fact that Moen is selling this as an OEM replacement for its own fixtures.
The reason Moen’s version is worth the price over a generic push-n-lock: rubber stoppers on cheaper kits have a habit of flipping inside out when the drain opens, blocking flow or refusing to seal closed. Owners who have tried the generic versions and then gone back to OEM report the difference is immediate — a tight seal when closed, unobstructed drainage when open. The Moen part sealed first try in those cases and did not require swapping out the drain base if the existing Moen base was intact. The chrome finish reads as OEM and cleans down easily, so it does not build up the calcium film that cheaper plated finishes do.
Two things to plan for. First, this is a trim-and-stopper kit, not a full waste-and-overflow assembly — no gasket is included, and most owners reuse the existing one, so have a spare gasket on hand if your old one looks worn. Second, if your tub has a two-screw overflow and you want a one-screw config, you need the separate Moen conversion part #142538; it does not ship in the box. Beyond those two notes, the standard-kit install is fast and the result is a drain that does what it should.
Why OEM Wins
- All-metal trim construction with a chrome finish built for long-term appearance.
- Push-N-Lock stopper opens with a simple push and closes with a pull — no rubber flap to flip.
- Fits 1-1/2 inch NPSM threaded drains, with the overflow cover included.
- Moen limited lifetime warranty backs the trim against defects.
What To Plan For
- No gasket included — most owners reuse the old one, so have a spare if yours is worn.
- Two-hole to single-hole overflow conversion requires a separate Moen part (#142538), sold separately.
- Standard-size drain trim, so measure the tub before ordering — some buyers find it sits larger than expected.
The OEM play: buy this to replace a worn Moen push-n-lock trim and keep the existing base; the seal will land first try and the chrome will outlast the cheap copies.
skip it if: you are starting from scratch on a non-Moen tub — a full waste-and-overflow kit elsewhere on this list gives you everything in one box.
6. Westbrass Tip-Toe Sch. 40 ABS Bath Waste with Two-Hole Elbow, Matte Black
A 1-1/2 in. schedule 40 ABS waste-and-overflow assembly with tip-toe stopper, two-hole elbow, shoe, and tee in matte black.
When the whole drain system is coming out, the Westbrass D4931-62 is what you want. It is a 1-1/2 inch schedule 40 ABS bath waste assembly with the tip-toe stopper, a two-hole faceplate and two 1/4-inch-20 x 1-1/2 inch plated brass screws, a 12 inch x 4 inch schedule 40 ABS tube section, and a schedule 40 ABS two-hole elbow, shoe, and tee. Schedule 40 is the wall-thickness designation in the plastic pipe family — thicker than the thin-wall pipe often used on cheap kits, so it holds up to hot water and doesn’t flex in service. Buying the full kit in one box saves a lot of chasing parts, and the matte black finish coordinates with the current matte black shower fixtures that a lot of remodelers are installing.
The tip-toe stopper lives up to its name — press it with a toe to close, press again to open — which is easy on knees and easy on the day-to-day. Owners replacing old brass and copper plumbing report that when the original plumbing was in reasonable shape, the install takes about an hour or less, and the toe stopper is a meaningful upgrade over the old chain style. On the outside, the matte black finish reads well against tile and does not show water spots the way polished metals do.
Two honest notes. First, the plumbing in this kit uses a cement-style solvent-weld joining method on the ABS parts, so it is not adjustable the way a slip-nut p-trap is — you commit to the orientation you cut and cement. Second, the outlet outside diameter matches schedule 40 fittings, but a very small number of installs have found the ABS walls thinner than expected at the joint, which is worth watching during dry fit. Plan the run before you cement, dry-fit twice, and it goes together cleanly.
The complete-kit advantage: you are replacing the whole waste assembly — the tube, elbow, tee, drain, and overflow are all in the box, so there is no chasing the right bushing at the hardware store at 7 p.m.
Fit it right the first time: because the ABS joints are solvent-weld, dry-fit the whole assembly before any cement touches a fitting. Once it is joined, that orientation is locked in.
Made for you if: you are pulling out the whole waste-and-overflow system and want a matte black finish with schedule 40 ABS right out of one box.
Look at the DANCO instead if: you want a plastic-tube kit that stays adjustable during install rather than a solvent-welded assembly.
7. Keeney K630PVCDSBN Foot Lok Stop Bathtub Drain Kit, 1-1/2-Inch
A 1-1/2 in. schedule 40 PVC drain kit with solvent-weld joints and an all-metal foot lok stop stopper.
The Keeney K630PVCDSBN is the pick for anyone who wants a PVC drain kit rather than an ABS one, and the choice matters if your existing plumbing is PVC and you want to cement the new assembly straight onto it. It is a 1-1/2 inch PVC schedule 40 drain kit that fits standard-size tubs and ships with the brushed nickel trim, drain, and overflow plate plus all hardware. The foot lok stop is a press-with-foot stopper; step on it to close, step on it again to open. The included stopper is all-metal and heavy, which is a real step up from the flimsy plastic stoppers shipped on many budget kits — buyers swapping out big-box-store kits note the difference immediately.
What makes this kit the pick for solvent-weld installs is the joints. Every pipe joint uses solvent welding, meaning the pipes are joined with PVC cement rather than slip-nut fittings. That sounds like more work, but it is actually the point: solvent-welded joints do not develop the small weeping leaks that slip-nut joints sometimes do over years behind a tub. Owners who have swapped from slip-nut kits to this one report no leaks at all from the cemented joints. The tarnish-free brushed nickel trim holds up to bathroom humidity without spotting, and the exposed drain and overflow faceplate match most contemporary brushed nickel bathroom fixtures.
Worth being honest about two things. First, if you are not comfortable with solvent-weld plumbing, this is not a kit to learn on — you cut, dry-fit, and cement one shot, and a mistake means re-doing the pipe run. Second, the set is sized to fit standard tubs, but there is no slip-nut adjustability after install; everything has to be right the first time. For a behind-the-tub install where you want to walk away and not think about it for years, that trade is a good one.
Built To Last
- Schedule 40 PVC tubing and solvent-welded joints cut the risk of small weeping leaks behind the tub.
- All-metal heavy stopper is a step up from the plastic stoppers on discount kits.
- Tarnish-free brushed nickel trim holds up in a wet bathroom without spotting.
- Fits 1-1/2 inch standard-size tubs and ships with all hardware.
Know Before You Buy
- Solvent-weld installation is not adjustable once cemented — dry-fit carefully before you commit.
- Schedule 40 PVC is thicker pipe, so if your existing drain line is thin-wall you may need an adapter.
- Not ideal if you prefer the slip-nut adjustability of a p-trap style kit.
Best for: a behind-the-tub install where you want solvent-welded schedule 40 PVC and you are comfortable working with pipe cement.
pass on it if: you want an adjustable slip-nut drain or you are not ready to cut and cement pipe — the DANCO kit is a friendlier starting point.
8. KOHLER K-7272-CP Clearflo Slotted Overflow Bath Drain
The Kohler slotted overflow pick — no internal linkages, so the overflow pipe clogs far less.
If you own a Kohler tub, the K-7272-CP Clearflo is the drain the tub was designed around. It uses a slotted overflow design with no internal linkages — meaning no moving parts inside the overflow pipe itself, which is exactly where a standard drain tends to clog over time. It ships with a schedule 40 PVC tee and pipe, a metal overflow cover, and a toe-tap stopper that closes with a press of the toe. The finish is Kohler’s polished chrome, which is built to resist corrosion and tarnishing, and the ball-joint construction makes the assembly easy to angle during install without stressing the pipe joints. It fits Kohler’s Elevance, Archer, Underscore, Rêve, and Parity baths and whirlpools — so if you own one of those, compatibility is one less thing to worry about.
Where this kit reads best is against the tub itself. The slotted overflow piece is what pulls attention in the reviews — it gives the tub a cleaner, more contemporary line than a round overflow plate. Owners with a Kohler tub who want the drain to look like it always belonged there tend to land on this drain first. The chrome finish on the trim is polished rather than brushed, so it reflects the tub interior and reads bright against white acrylic or cast iron.
The clear caveat is the design itself. The “no internal linkages” feature that prevents overflow-pipe clogs also means there is nothing catching hair at the drain opening — a reminder that hair needs to be fished out manually rather than caught in a basket. That is the trade for the cleaner overflow design and it is worth knowing before you buy, especially in a home with long-haired bathers. It is also the priciest kit on this list, so consider it the right pick when you want a Kohler tub to look finished rather than when you want maximum bang for the buck.
Suits Kohler owners best: if your tub is one of the Kohler models this drain was made for, the fit, finish, and slot design come together as a factory-grade replacement.
The honest trade: no internal linkages means nothing in the overflow pipe to clog, but also nothing at the drain opening catching hair — so budget for a manual hair pull every so often.
The Kohler match: buy this when you own one of the Kohler baths it is specified for and want the drain to look like it came with the tub.
Skip it for: a universal tub or a house with several long-haired bathers — the Citymoor’s built-in hair filter is a better fit for that bathroom.
Understanding the Specs
Drain Thread Size
This is the measurement printed on the drain shoe — the threaded fitting where the stopper sits. The two standard sizes in US tubs are 1-3/8 inches and 1-1/2 inches, both measured in NPSM (national pipe straight mechanical) thread. A 1-1/2 inch drain waste is the modern standard; older tubs often use 1-3/8 inch. The easiest way to check yours is to pull the old stopper and look at the size written on the drain body. If you cannot tell, look for a kit that includes a thread adapter bushing — that small metal ring steps between the two sizes so the same drain fits either tub.
Stopper Style
The stopper is the piece you interact with daily, so pick the one that matches how your household uses the tub. A lift-and-turn stopper is lifted by hand and rotated to lock the drain open or closed — intuitive, tool-free, and good for anyone who prefers twisting over stepping. A touch-toe or tip-toe stopper closes with a press of the foot and opens with another press — the easiest on knees and bare feet. A push-n-lock is a push-to-close, push-to-open design. If you already have one style and want to keep it, match the stopper style when you buy; if your tub has a chain-and-plug setup, any of these is an upgrade.

Final Thoughts: The Verdict
For most bathrooms, the bath tub drain kit winner is the WELLUP Brushed Nickel Bathtub Drain Conversion Kit because it ships with everything a stopper-swap job needs — a solid brass and stainless steel body, a thread adapter that fits either 1-3/8 inch or 1-1/2 inch NPSM drains, and a two-hole faceplate — so you are not chasing missing parts mid-install. If you want a full waste-and-overflow assembly with one box covering the pipe run behind the tub, the Westbrass D4931-62 has the schedule 40 ABS tee, elbow, and shoe ready to cement in. And for a Kohler tub where you want a factory-match slotted overflow with no internal linkages to clog, the Kohler K-7272-CP Clearflo is the one to reach for — just budget on pulling hair manually since nothing catches it at the drain opening.
