Best wall safes: what an in-wall safe between the studs can and can't do

Concealment vs protection: what a wall safe is for

A wall safe sits in the cavity between two wall studs, behind a mirror, a picture or a closet door. Its job is to keep small valuables (cash, a passport, a spare key, jewelry you wear often) out of sight and behind a lock. That is useful. It isn't the same as protection against a determined burglar or a fire.

None of the three wall safes on this page carries a UL burglary rating. Protex describes the PWS-1814E as "Burglary Resistant," which is the maker's wording, not a lab result. The published steel is modest: 1.5 mm on the Homak and a 16-gauge body on the SnapSafe, against 12-gauge on the Stealth HS4 floor safe. And the anchor is the wood studs on either side, not a concrete floor. So a wall safe works best when nobody knows it's there.

If you need protection rather than hiding, a burglary-rated safe bolted to the floor is the stronger answer. That's why the Stealth HS4, with a maker-stated UL RSC rating, appears here as an alternative. UL's RSC Level 1 covers a "five-minute attack by one technician using common hand tools" (UL), a measured result no wall safe here claims. See our best home safes for more rated options.

Stud depth and sizing

Depth is the constraint. A nominal 2x4 stud actually measures 1 1/2 x 3 1/2 in (Family Handyman), so a standard 2x4 wall gives you about 3 1/2 in of stud depth plus the thickness of the drywall you cut through. The wall safes here are built to that envelope:

• Protex PWS-1814E: 3 7/8 in deep outside, 3 in deep inside, with a 16 x 20 in flange that covers the cut. It's "designed to be installed between 16" o/c wall studs" (Protex).
• SnapSafe 75414: 44 x 16.25 x 4 in outside, 41.6 x 11.8 x 3.6 in inside. The manual says to confirm 14.5 in between the studs.
• Homak WS00017001: listed at 4 x 17.25 x 11.75 in, and it fits between two 16 in center studs in a wall or a floor. Homak doesn't publish interior dimensions or capacity.

SnapSafe's manual also says to use an interior wall, one that is "free of all hidden obstructions," so check the bay you've chosen with a stud finder and look for outlets or switches nearby before you commit. Three to 3.6 in of interior depth rules out anything bulky. Think flat: documents, cash, passports, jewelry on the SnapSafe's hooks, a spare key. Measure your wall before you buy; the stud spacing, the cavity depth and anything already inside the wall decide whether a given safe fits.

Locks, lockouts and backup entry

A wall safe is opened more often than a floor safe in a closet, so the lock gets daily use. The three picks take different approaches:

• SnapSafe 75414: an electronic keypad powered by four AA batteries, with an audio and LED low-battery warning and a key backup. The manual says five wrong codes trigger a 5-minute lockout, and the door opens a few inches on its own under spring tension once the right code goes in.
• Protex PWS-1814E: a digital electronic lock driving two motorized 3/4 in chrome bolts, and the door opens automatically. If the power fails, there's both a key override (two keys included) and a power override.
• Homak WS00017001: a tubular key lock and nothing else. There are no batteries to replace, but anyone with the key has access, so where you keep it decides how secure the safe is.

Whichever you choose, test the lock before the safe goes in the wall, as SnapSafe's manual instructs. A fault is far easier to deal with while the safe is still on the workbench.

Wall safe or small bolt-down safe?

The two alternatives on this page exist because some readers will be better served by a safe on the floor. Here's the trade in plain terms, using the Protex as the typical wall safe:

If the aim is keeping a spare key, some cash and a passport away from visitors and children, a wall safe does the job and stays out of sight. If the aim is stopping someone who is already searching the house, a rated floor safe is the better tool.

No wall safe here has a fire rating

Plainly: none of the three wall safes states any fire rating, and neither does the SentrySafe X055 alternative. The Stealth HS4 claims 60 minutes at 1,200°F with no lab named. If you keep papers you can't replace, put them in a UL-classified fire chest or fire safe, not a wall safe. Our document safe picks cover the chests.

How we ranked these wall safes

We haven't bought, installed or lab-tested any of these safes. The three wall safes and the X055 are access boxes, scored on our access-control rubric (access reliability, construction and pry resistance, child-access standards, mounting, support). The Stealth HS4 is scored on our fire and home-safe rubric, so its score isn't comparable with the others. Both rubrics are published on how we rate.

The SnapSafe leads on the heaviest published steel (see our steel gauge explainer for what 8-gauge and 16-gauge mean in inches), a keypad with key backup and a lifetime warranty. The Protex is second: a typical picture-size wall safe with two override routes, held back by an unpublished body gauge and a one-year, parts-only warranty. The Homak is simplest and lightest. The HS4 and X055 rank below the wall safes, even though the HS4 is a higher tier and the X055 outscores two of them, because neither goes in a wall; they're here for readers who decide concealment isn't enough.

Our search of CPSC recall notices on 2026-09-19 found no recall for SnapSafe, Protex, Homak, Stealth or SentrySafe safes. Each product card shows its dated recall check.

What to look for in a wall safe

1. A fit for your studs. All three are built for 16 in on-center framing. Check the spacing and cavity depth in the exact wall you'll use.
2. Published steel. The SnapSafe publishes gauges for door and body, the Homak a 1.5 mm thickness, and the Protex a door spec but not a body gauge.
3. Backup entry. The Protex has a key override and a power override; the SnapSafe has key backup and a low-battery warning; the Homak is key-only, with no batteries to fail. Our lock guide covers keypads vs keys.
4. A way to hide the cut. The Protex flange covers the opening; any of them can sit behind a mirror or picture, as Homak suggests.
5. Warranty. SnapSafe warrants the 75414 for the life of the product; Homak gives one year; Protex gives one year, parts only.

Which wall safe fits your space

• A tall, narrow stash for documents, jewelry and keys: the SnapSafe 75414, if you have a 42 in run of clear wall between two studs.
• A picture-sized safe behind a frame or mirror: the Protex PWS-1814E, whose 16 x 20 in flange covers the cut.
• The simplest option, with no electronics: the Homak WS00017001, which also fits between floor studs.
• You can't or won't cut a wall: the SentrySafe X055 bolted inside a cabinet or closet.
• You need real burglary protection: the Stealth HS4 bolted to a closet floor.

What fits inside, and what comes with it

SnapSafe's manual lists five shelves, a shelf mat, a document holder, a jewelry and key hanger, a picture frame hook and eight lag screws in the box for the 75414. The Protex has a velvet interior with two removable shelves, and the Homak has a black foam lining. With 3 to 3.6 in of interior depth, plan on flat items: folders laid on a shelf, envelopes of cash, passports, small jewelry boxes and keys. Anything thicker belongs in a floor safe.

Keeping a wall safe secret

Because concealment does most of the work, the habits around a wall safe matter as much as the hardware. Cover it with something that belongs on that wall; SnapSafe includes a picture frame hook for exactly that, and Protex's flange sits flat for a frame or mirror to hang over. Install it when you're alone in the house, and keep the location to the people who need it. If a contractor or painter will be working in the room, empty the safe or choose a spot they won't need to open up. And if you rent, get your landlord's permission before you cut into a wall.

How installation works

We're summarizing SnapSafe's published steps for its in-wall safes, not describing our own install. Follow your safe's instructions exactly.

1. Test the safe's lock before it goes in the wall.
2. Choose an interior wall that is "free of all hidden obstructions."
3. Find the two studs with a stud finder, mark their inside edges and confirm the spacing (14.5 in for SnapSafe).
4. Mark level top and bottom cut lines at the height the safe needs (42 in for the 75414).
5. Cut the drywall between the studs and remove the section.
6. Slide the safe in, pre-drill through each mounting hole into the stud, and fasten with the lag screws provided.
7. Change the factory default code before you store anything; the manual says you must.

If you aren't comfortable locating wiring and plumbing, SnapSafe's own advice is to consult a professional contractor.

Where to put a wall safe

Homak suggests the WS00017001 "can be concealed behind a mirror, picture frame, or inside a closet" (Homak), and says it fits between floor studs too. A closet wall behind hanging clothes keeps the cut out of view. Our guide to where to put a safe in your house covers concealment in more detail.

Mistakes to avoid

• Cutting before checking for pipes, wires and ducts.
• Buying before measuring stud spacing and cavity depth.
• Using a wall safe for papers you can't replace; none of these has a fire rating.
• Leaving the factory code in place.
• Hanging the cover picture somewhere a picture would look out of place, which draws the eye to the spot.
• Keeping the backup key next to the safe, or telling guests and contractors where it is.
