Your old door has a hole spacing you cannot change, and that single measurement decides which antique door knob sets will even bolt on. So buy by backset and door thickness first, style second. The quick answer: a set that lists both a 2-3/8″ and a 2-3/4″ backset plus a 1-3/8″ to 1-3/4″ door thickness range will drop onto most interior doors without new drilling. Everything below is sorted around that reality.
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.
Glass, brass, and skeleton-key styles all look similar in photos, yet they behave very differently once installed. The list below ranks each set by fit range, locking type, and how it holds up in daily use. Read on for the best antique door knob sets for a bedroom, a bathroom, or a full hallway swap.
Our Picks at a Glance
How To Choose The Best Antique Door Knob Sets
Vintage knobs are sold on looks, but they are installed on measurements. Get the measurements wrong and a beautiful set sits in its box while you re-drill a door. Get the backset and thickness right and the swap takes one screwdriver.
Measure the backset before you fall for a finish
Backset is the gap from the edge of your door to the center of the knob hole. Standard doors use either 2-3/8″ or 2-3/4″, and a set that lists both covers you either way. Many vintage knob sets also fit doors from 1-3/8″ to 1-3/4″ thick, which is the common range for interior doors.
Decide whether the door needs to lock
A privacy knob locks from the inside and is meant for bedrooms and bathrooms. A passage knob never locks, so it suits closets, hallways, and living rooms. A mortise set uses a skeleton key and a lock body sunk into the door edge, which is a bigger job than swapping a bored-hole knob.
Match the material to the traffic
Glass knobs bring the period charm but demand care in a busy hallway. The zinc-alloy sets in this guide are described by their makers as rustproof, and the stainless-steel set as rust-resistant — worth checking the listed material if the door gets grabbed dozens of times a day.

In‑Depth Reviews
1. Glass Door Knobs, Privacy Vintage Brass Door Knobs, 6 Pack
Our pick — 4.5+★ from 600+ verified ratings; the strongest balance of quality and price.
Clear rosette glass on brass plates, and six of them in one box for a whole hallway.
If you want the diamond-glass look on every bedroom door without a second order, this six-pack is the crowd favorite: 4.5+ stars across 600+ ratings. The knobs are clear rosette glass set on sturdy zinc alloy plates, and the finish is antique brass. A six-pack means you can do bedrooms, a bathroom, and a spare door in one pass with matching hardware.
What wins people over is the visual payoff — this is the most-praised trait of the set by a wide margin, with glass quality close behind. The privacy lock is a push-pin button inside that you twist the knob to release, and an emergency release hole lets you pop it open from outside with a hex key or any thin tool. Owners describe the turn as short and light — one customer notes the knob needs only a quarter turn to operate, so the release is quick in daily use.
The honest catch is glass. It is not a material you want on the door your kids slam. Durability feedback runs mixed, and this is a set to treat with a little care rather than a heavy-traffic swing door. Installation is a screwdriver job, and the plates are built to cover pre-existing holes, so a straight swap is realistic on both new and old doors.
Where it wins
- Six matching knobs, enough to dress a whole hallway in one order.
- Glass-and-brass look that owners single out as the reason they bought it.
- Push-pin privacy lock with a tool-release hole for emergencies.
- Fits pre-existing holes and installs with only a screwdriver.
Worth knowing
- Glass construction means the knobs want gentle handling.
- Durability feedback is split, so this suits lighter-traffic doors.
- Privacy function only — no keyed entry from outside.
Go for it: period charm across a row of bedroom and bathroom doors, with matching hardware in one box.
Think twice: if the door is a high-traffic family bathroom or a slam-prone entry, a metal set takes the knocks better.
2. Gobrico Interior Door Locksets in Antique Brass, Octagonal Crystal Doorknobs, 5 Pack
Octagonal cut glass that owners say makes a plain door look far more expensive than it is.
The diamond-shaped knob is the reason to look here. Each one is octagonal clear glass on a zinc alloy rosette with an antique brass finish, and you get five in a pack for bedrooms and bathrooms. If your cabinets and trim already lean vintage, this is the set that matches the era rather than sitting on top of it.
Appearance is the runaway favorite trait, and it is earned — the cut glass catches light in a way flat metal does not. Installation is a screwdriver job with every latch, spindle, strike plate, screw, and hex key in the box, so you are not hunting for parts mid-job.
Know the trade-off before you buy. Glass is the weak point on a handle you turn every day, and durability is the most-discussed concern on this set — buyers report glass parts breaking off or knobs working loose after a few weeks. That does not make it a bad set for a lightly used door. It suits a lightly used guest bath or a decorative bedroom, not the door a household of four pounds through.
What sells it: the octagonal glass shape reads vintage in a way most reproduction knobs miss, and five matching units cover a small run of doors.
The real-world caveat: plan the install on doors that get gentle use, and check every screw and spindle snug before the first turn.
Pick this for: a guest bath, a spare bedroom, or any door where the look is the point and the traffic is light.
Not the set for: a busy family hallway where a knob takes constant hard grabs.
3. Goldenwarm Vintage Brass Door Knobs Interior, Privacy Door Knobs, 6 Pack
A six-pack with a thumb-turn lock that adjusts to two backsets and two door thicknesses.
If you are re-knobbing a whole house, the fit range is what earns this pick. The set handles backsets of 2-3/8″ or 2-3/4″ and doors from 1-3/8″ to 1-3/4″ thick, which covers most interior doors in a normal home. Six units plus a stainless steel build with a vintage brass finish make it a straightforward one-order upgrade.
The locking setup is kid-friendly by design: a thumb turn locks it from inside, no key needed, and a coin or flat tool opens the exterior emergency release. Install takes a screwdriver and the box includes the latch, strike plate, screws, and an installation guide. Appearance and installation are the two traits that draw the most praise, so the visual payoff on a fix-and-flip or a tired hallway is real.
You should know that quality and locking feedback are mixed here — the lock mechanism is the single biggest point of friction, and a few units reportedly arrive with a mechanism that will not catch. This is a strong fit for a whole-house swap where you want matching hardware at a mid-range tier, provided you test every lock the day the box lands and use the support line if one misbehaves.
Why it earns a spot
- Adjustable to 2-3/8″ or 2-3/4″ backsets, covering most standard doors.
- Thumb-turn privacy lock with a coin-release hole on the outside.
- Complete hardware and instructions in every box.
- Six units of matching stainless steel and brass finish.
Check before ordering
- Lock mechanism feedback is mixed, so test each one on arrival.
- Intended for interior use only — not for exterior doors.
- One hand orientation is listed, so confirm your door swing.
Best match for: a full interior-door refresh where the same hardware should run door to door.
Worth a rethink if: you need exterior-rated hardware or a keyed lock.
4. Probrico Passage Door Knobs Interior, 6 Pack, Antique Brass
Six locking-free knobs in rust-resistant stainless steel for the doors that never need privacy.
Passage knobs are the unsung half of a re-knob job. This set is built for closets, hallways, living rooms, and porch doors — anywhere you want the vintage look but no lock. The stainless steel body has a brass finish and is rust-resistant, so it holds its look through daily grabbing and humidity.
Fit is the strong suit. It takes a 2-3/8″ or 2-3/4″ backsets and doors from 1-3/8″ to 1-3/4″ thick, and the knob is reversible for left or right doors. Installation needs only a screwdriver, and the whole set of six is a tidy match for the privacy knobs elsewhere in this list if you are doing a mixed hallway. Quality is the trait owners appreciate most, with appearance and installation close behind.
The one thing to measure before you buy is your door thickness and backset — the set fits standard ranges, and a builder-grade oddity can fall outside them. Color accuracy also draws split feedback, so check that the brass tone suits your trim before committing a whole hallway to it.
Why it is here: six no-lock knobs that fit both common backsets and both door-thickness ranges, in a stainless steel build that resists rust and fading.
The catch to note: color varies enough for some buyers that it pays to look at the finish against your existing hardware first.
Reach for this when: you want vintage knobs on closets, hallways, and living rooms with no privacy or keyed lock.
Skip it for: bedrooms and bathrooms, where the lock-free design leaves you without privacy.
5. MRML Door Knobs Antique Brass Retro Passage, 2 Pack
Two knobs, not six — the right order size when only a couple of closet doors need saving.
Not every project is a hallway. This two-pack of antique brass retro passage knobs fits the classic use case: a closet, a hallway, or any door that should open freely with no lock. Each knob is roughly 2.637 × 2.637 × 2.567 inches, with the knob body in aluminium alloy and the round base in zinc alloy.
The fit range makes it flexible — it works for left or right doors, doors around 1-3/8″ to 1-3/4″ thick, and a latch backset of either around 2-3/8″ or 2-3/4″. Owners rate the build quality and finish highly; the solid feel and easy install are the reasons it lands in the mid-range.
A couple of honest limits: the ease of use and fit feedback is mixed, with some finding the latch mechanism less smooth and a few doors needing adjustment to line up. Measure before you order and the install is straightforward. This two-pack suits a small job done well, not a bargain multi-pack.
The case for it
- Two-knob pack sizes to the job instead of overshooting.
- Adjustable latch fits 2-3/8″ or 2-3/4″ backsets.
- Reversible for left or right doors.
- Solid aluminium and zinc build that owners rate highly.
What to expect
- Passage function only — no lock at all.
- Mixed feedback on ease of use and door fit.
- Smaller pack means a hallway job needs more than one order.
Made for: a two-door project — a closet and a hall door — where a full six-pack would be overkill.
Look past it if: you need privacy or a key, or you are outfitting a whole floor.
6. Orger Octagonal Crystal Door Knobs, 5 Pack, Antique Bronze
Antique bronze glass knobs for the bathroom, if you prefer a deeper, darker period tone.
Bronze is the difference here. Where most glass knob sets run bright brass, this one lands in a deeper antique bronze on zinc alloy bases with durable clear glass. If your bathroom fixtures and cabinet pulls already lean dark metal, this is the set that ties the room together.
The locking setup is a push button inside, with an emergency release hole you open using the wrench that comes in the box. Five units cover a bathroom plus a couple of bedrooms, and the install is a Phillips-screwdriver job with instructions and a template included for new doors.
Before you commit, be clear on the weak point. Glass and a small handle mean some owners describe the edges as sharp and the turn as uncomfortable, and durability is the most-discussed concern — the honest read is that this is a decorative set for lighter-use doors. The appearance is what earns it its place; five matching bronze-toned glass knobs at this tier look far richer than the hardware they are.
What lands: the antique bronze tone and octagonal glass shape give a genuinely older, moodier look than the brass versions.
The fair warning: glass edges and a small turn surface ask for a gentle grip, and heavy daily use is not where this set shines.
Choose it for: a bronze-themed bathroom or a lightly used bedroom where the vintage look is the main event.
Pass on it if: the door gets constant traffic or you want a knob that ignores rough grabs.
7. naubea Antique Brass Door Knob Privacy, Old Style Round Knob
A single brushed-brass round knob with a keyless privacy lock — simple, and heavier than most.
This is a one-knob fix rather than a pack. It suits the specific job of swapping a single bedroom or bathroom door where the existing hardware has failed. The round old-style knob is brass with a brushed finish, keyless from the outside, and it carries a listed 0.84 kg — meaningfully heavier in the hand than the smaller multi-pack knobs on this list.
At 2.75″ long and 2.6″ wide, the knob body is a modest size, and the package includes the privacy knob, adjustable latch, strike plate, spindle, and all the screws. Installation is designed for a minutes-long swap with the included instructions, and it works on both left- and right-handed interior doors. A 120-day return window backs it if something is not right.
The catch is real and worth naming: the knob is tight to turn, and the round shape gives your fingers less to grip than a lever or a larger knob. Feedback on ease of use and ergonomics runs negative, and that is a genuine fit issue for smaller hands or anyone who wants a light twist. Match it to a lightly used bedroom or guest door and the look is worth the tight turn.
What makes it stand out
- Round brushed-brass shape with a distinctly older feel than most packs.
- Single-knob solution for a quick one-door replacement.
- Adjustable latch and full hardware included.
- 120-day return window for confidence.
The trade- off
- Tight, small knob that is hard to turn for some hands.
- Brass-toned finish feedback varies, so check tone against trim.
- One knob only — a hallway job needs several orders.
Good fit for: a single bathroom or guest door where the vintage look matters and the lock must stay keyless.
Better off with a lever or larger knob if: gripping and turning comfortably is the priority.
8. ToPToToo Mortise Lock Set for Interior Door, Vintage Brass, Skeleton Key
A complete mortise body with skeleton key — the answer when the old lock guts have given up.
Old doors do not take modern bored-hole knobs. They take a mortise lock, the lock body that sits inside a slot cut into the door edge. This set gives you that body, a brass finish, and a skeleton key, and it fits doors 1-3/8″ to 1-3/4″ (35-45 mm) thick. Check that thickness first, because it is the make-or-break spec.
Where it earns its keep is the look and the function — appearance and functionality are the two most-praised traits, and owners mention it works well for the money. It suits an interior door or a bathroom or bedroom where you want a period-correct knob and a keyed lock that reads vintage. For the price tier, it is a complete swap for failed old hardware rather than a cosmetic upgrade.
Be careful with the metal. Quality runs mixed and durability feedback leans negative, so a handful of units feel lighter than the original cast hardware they replace. Treat this as a budget restoration fix for a door that is not a daily battle ground, and plan to fit it with patience.
The value case: a full mortise lock body with skeleton key at a budget tier, sized for 1-3/8″ to 1-3/4″ doors.
Measure twice: the metal is not the heaviest, so it suits lighter-use doors rather than a high-traffic swing.
Worth a look for: a period home where the original mortise lock has failed and you want a keyed vintage replacement.
Not your pick if: the door takes constant use or you want modern deadbolt security.
9. Ruigrit Vintage Skeleton Key Mortise Lock Set, Polished Brass
Rustproof zinc alloy, a steel core, and a dual-action skeleton key that works from both sides.
The headline here is the hardware that comes in the box: two trim plates, two knobs, one mortise lock body, twelve mounting screws, a 1/4″ square spindle, a strike plate, and two skeleton keys. It fits 1-3/8″ to 1-3/4″ doors and is reversible for left- or right-handed doors by flipping the locking tab. The body is rustproof zinc alloy with a reinforced steel core, in a polished brass finish.
If you are restoring an old door on a budget, this is a strong candidate: pre-assembled, with a 5-year warranty against defects, and install is measured in minutes once the mortise slot is clear. The dual-action key works from both sides, and a 5-pin cylinder is designed to resist tampering — a step up from a simple thumb latch.
Two honest notes. The install and fit are praised, but durability and lock feedback run mixed, so not every unit feels as solid as the original it replaces. It also uses a skeleton-key format, which is period-correct but not modern security. It suits a period home where the look is the goal.
Why this one
- Full kit with two skeleton keys, spindle, strike plate, and screws.
- Rustproof zinc alloy with a reinforced steel core.
- Works on left- or right-handed doors by flipping the tab.
- 5-year warranty against defects.
Things to know
- Durability and lock feedback run mixed across the range.
- Skeleton-key security is vintage, not modern.
- Mortise install means a slot in the door edge, not a simple screwdriver swap.
The right call for: a period restoration where you want a complete mortise kit and a warranty behind it.
Look elsewhere if: you want keyed security or a knob swap that takes one screwdriver and no woodwork.
Understanding the Specs
Backset — the measurement that decides fit
The backset is the distance from the door’s edge to the center of the knob hole. Most interior doors use either 2-3/8″ or 2-3/4″, and a set that lists both can cover your doors either way. Get this measurement first, before you look at finish.
Door thickness — the make-or-break range
Two common ranges appear in this category: 1-3/8″ to 1-3/4″ for standard interior doors, and the same range stated in both inches and millimeters on some listings. A door outside that range needs special hardware, so measure the actual door slab, not the frame.
Privacy vs passage — the lock question
A privacy knob locks from the inside, usually with a push pin or thumb turn, and has an emergency release on the outside. A passage knob never locks. Decide which door and which privacy need first, because you cannot add or remove a lock later.
Mortise vs bored-hole — two different installs
A mortise lock body sinks into a slot in the door edge, which is how old doors were built. A bored-hole knob goes into the round holes a modern door already has. They are not interchangeable, and a mortise set needs more than a screwdriver.

Final Thoughts: The Verdict
For the majority of shoppers, the antique door knob sets winner is the Calzibeno Glass Door Knobs, 6 Pack because it pairs the most-praised vintage glass-and-brass look with a simple screwdriver install and six matching knobs in one box. If you want a full-house swap with adjustable backsets and a thumb-turn privacy lock, grab the Goldenwarm Vintage Brass Door Knobs, 6 Pack. And for a closet and hallway run with no locks at all, the Probrico Passage Door Knobs, 6 Pack is the one to reach for.
One last nudge before you order: measure your backset and door thickness first, then buy by fit. Many returns in this category trace back to a backset that did not match the hole’s distance from the door edge.
