Tandefio Vacant Occupied Bathroom Lock, in Use Deadbolt with

The Verdict

Is the Tandefio Vacant Occupied Bathroom Lock worth your money? Short answer: if you’re tired of people rattling the knob while you’re indisposed, yes. If you need real security, no — but that’s not what this is for. Let me break down what 195 Amazon reviewers (3.9 stars) are actually saying, and where this lock earns its keep.

What’s in the box: You get the deadbolt assembly (both interior and exterior plates), the thumb turn with the occupancy indicator, a standard latch bolt, strike plate, and all mounting screws. The finish is a brushed stainless that resists fingerprints well — a small thing, but it matters in a bathroom. As shown in the product image, the indicator is a rotating disc that flips from green (vacant) to red (occupied) as you turn the thumb latch. It’s a deadbolt, not a doorknob, so installation requires a 2-1/8" bore hole and a 1" latch hole — standard for most US residential doors. If you’re replacing an existing deadbolt, it’s a 10-minute swap.

Real-world performance: The thumb turn has a satisfying, positive click when it engages. The deadbolt throws fully with about a half-turn, and the indicator movement is synchronized — no lag, no half-red/half-green confusion. I’ve tested it on a 1-3/8" hollow-core door and a 1-3/4" solid door; both fit fine with the adjustable backset (2-3/8" to 2-3/4"). One thing I appreciate: the exterior plate is flat with no screws accessible when the door is locked, so it’s not easy to tamper with from the hallway side.

What buyers consistently praise: The visual indicator is the star. One reviewer put it plainly: “No more yelling ‘occupied!’ through the door. The red/green is visible from down the hall.” Another noted: “Installed in five minutes, and it looks way more expensive than it is.” The build quality of the outer housing — solid stainless, not zinc alloy — gets repeated shout-outs. For a privacy lock, that’s the right material choice.

Where it falls short: The internal indicator mechanism is plastic, and that’s where the 3.9 rating starts to make sense. Several reviewers report the disc sticking after a few months in steamy bathrooms — the plastic swells, and the red/green gets stuck halfway. One said: “Works great for three months, then the indicator started jamming. Had to lubricate it.” The included strike plate and screws are also flimsy — I’d swap them for #8 or #10 hardware immediately. And this is privacy-only; there’s no keyed cylinder, so if you want to lock a shared utility room or office, this isn’t the tool.

Who should buy this:

• Homeowners with a single-family bathroom — perfect, low-stakes upgrade
• Renters who want a quick, reversible install (it mounts with standard screws, no permanent damage)
• Anyone with kids who can’t remember to flip a slide bolt — the visual indicator is foolproof
• NOT for commercial restrooms, high-traffic public spaces, or anywhere you need actual security

FAQ: Q: Will this fit a door that has a standard doorknob? A: Yes, but it replaces the deadbolt position, not the knob. You’ll need a separate 2-1/8" bore hole above your knob. If you’re removing an existing deadbolt, it’s a direct swap.

Q: How does the indicator work mechanically? A: The thumb turn rotates a cam that drives both the deadbolt and a plastic disc. When the bolt is fully extended, the disc shows red. When retracted, green. No batteries, no electronics — purely mechanical.

Q: Is the lock secure against forced entry? A: No. The exterior plate is flat with no screws, which deters casual tampering, but this is a privacy lock, not a security lock. Anyone with a screwdriver could pry the plate off a hollow-core door in under a minute.

The Verdict: 3.7/5 — Buy it if you want a clear visual “occupied” signal without replacing your whole handle set. Skip it if you need a heavy-duty lock for high-traffic or security-sensitive doors.

For under $30 (check current price on Amazon), the Tandefio delivers the core feature — a visible, unambiguous vacancy indicator — with a decent stainless shell. The plastic internals and flimsy strike plate are the tradeoffs. If you’re handy with a screwdriver and willing to upgrade the strike plate, this is a solid value. If you want set-and-forget durability in a humid environment, spend a few dollars more on a commercial-grade unit. Either way, you’ll stop yelling “occupied” through the door.
