The measurement that decides everything is not the external one, it’s the internal compartment. A 15-inch laptop measures roughly 36×25 cm and needs an opening of at least 40×30 cm; a 17-inch one comes in around 40×28 cm and needs 45×35 cm, rising to 50 cm in width if the guest slips it into a padded sleeve. Below these sizes the computer stays on the bed and the safe is only good for the passport. Everything else, electronic access, log, anchoring, comes after.

The internal compartment, not the volume in litres
Catalogues state capacity in litres and overall dimensions. They tell you little. Always ask for the three useful internal measurements, the ones taken with the door open, net of the door frame and the reinforcements that often eat up two centimetres per side. On a safe sold as “35 litres, 43 cm wide”, you can end up with 39.5 cm net: the 17-inch laptop doesn’t fit, and the complaint reaches reception within a week.
Internal height matters less than width, but it isn’t irrelevant. With 19-20 cm clear, you can fit a laptop lying flat, a tablet, two cameras and a wallet. With 15 cm, the guest stacks things and then can’t close the door.
| Useful internal compartment (W x D x H) | What actually fits | Typical use | Indicative 2026 cost |
|---|---|---|---|
| 30 x 20 x 15 cm | documents, cash, watches, phone | three-star, standard rooms, hostels | €90-140 |
| 40 x 30 x 20 cm | 13-15in laptop lying flat, tablet | four-star, double rooms | €150-220 |
| 45 x 35 x 20 cm | 17in laptop, SLR camera with lens | four and five-star, business | €220-330 |
| 50 x 38 x 25 cm | laptop in a sleeve, small bag | suites, long-stay rooms | €330-500 |
These prices cover the unit alone, fitting excluded. On a fifty-room order, the supplier will almost always apply a 15-25 per cent volume discount, and it pays to include the safes in the furniture specification rather than buying them separately after opening: bought separately, they arrive after fitting and have to be installed in a finished room, risking drilling into an already painted panel.
Access, codes and who holds the key
The standard today is an electronic keypad with a four or six-digit code, chosen by the guest at each use and cleared automatically on closing. The key-operated model survives only in very small properties, and creates more problems than it solves: the key gets lost, has to be duplicated, and in the meantime the room is out of service.
Above the guest’s code sits the management’s master code, which opens any safe in the property. It should be changed whenever a new manager takes over, and known to no more than two people. The mistake I see most often is a master code left at the factory setting, four zeros or 999999, for years on end. It’s the same carelessness that leaves the items that go missing most easily from rooms unchecked.
Third level: the mechanical emergency key, under the front plate or behind the logo. It’s needed when the electronics fail. Keep a single copy, in the management safe, with a paper log of who uses it.
The access log
Mid and high-range safes store between 50 and 200 events: date, time, type of code used. You extract it with a handheld reader or via a service port, and the printout counts as evidence when a guest reports something missing. Anyone running a property with business guests should treat it as essential, because the classic case is a guest claiming they left three thousand euros inside, while the log shows a single access with the guest code at 23:40, and no master code access at all. It costs an extra €30-50 per unit. It’s worth it.
One practical detail to watch: the log must be extracted before the safe is reset, or it’s lost. Housekeeping staff almost never know this and need to be trained on it.
Batteries or mains power
Four AA alkaline batteries last twelve to twenty-four months in a room sold at 70 per cent occupancy. That sounds like plenty, but across eighty rooms it means one replacement a week, which belongs in the scheduled furniture maintenance plan, not something you deal with when the safe locks up at two in the morning with the passport of a guest who has a six o’clock flight inside it.
Mains power removes that problem and creates another: you need a socket inside the wardrobe or the piece of furniture, planned at the wiring stage. If the electrical design is already locked in, adding it later means a surface-mounted trunking or chasing into the wall behind a freshly fitted unit. The solution I recommend is a mixed one: mains power with a backup battery, with the socket planned alongside all the other sockets and USB ports in the room, on a circuit that isn’t controlled by the key card, otherwise the safe switches off when the guest goes out.
Where it goes
Inside the wardrobe, on a dedicated shelf, is the position that works best. The guest uses it while getting dressed, it stays out of sight of anyone entering the room, and the shelf is stiffened with a 25 mm panel instead of the usual 18. The shelf needs to be calculated for 40-60 kg of permanent load plus the jolts of opening and closing: on wardrobe designs for hospitality properties the safe compartment is drawn in together with the rest, with a side stop that hides the fixing.
Three fitting rules that always get skipped on site:
The fixing must pass through the back panel of the unit and anchor into the masonry behind it, with two 10 mm mechanical anchors. Anchored only to the chipboard, the safe comes away with the panel, and it has happened more than once.
Leave at least 3 cm clear above and to the sides, because the motorised door heats up and without air the electronics fail sooner. Sealed cabinets need a vent slot at the back.
The useful height is between 90 and 130 cm off the floor. Any lower and an elderly guest has to stoop and can’t read the display; any higher and they can’t lift the laptop out without overreaching.
In accessible rooms the height changes: controls between 90 and 110 cm, with 90×120 cm of clear space in front for a wheelchair to pull up alongside, a constraint that needs resolving on the drawing together with the other minimum room fit-out requirements.
The mistake of putting it in the bedside table
You see it in budget refurbishments: safe in the bedside table, next to the bed, convenient. It’s the worst position there is. The bedside table is light, often wall-hung, and offers no serious anchoring to the wall; a thief doesn’t bother opening the safe, they take the whole unit. If space forces that solution, the bedside table needs to be designed as a fixed, floor-standing structure, with an 18 mm plywood back panel and wall anchoring, not hung from the upright.
The same reasoning applies to the desk: a drawer with a built-in safe only works if the top is floor-standing on load-bearing sides.
How much it weighs on the budget, and what the classification says
For a four-star property, an in-room safe is among the requirements expected of that category under most regional regulations, which call for either a safe in the room or, as an alternative, a safekeeping service at reception. The regions aren’t aligned with each other, so the reference point remains your own region’s regulation.
Its impact on a room’s overall budget is modest: €200 on a complete fit-out of €6,000-9,000, under 3 per cent. It’s one of the few line items where cutting costs shows up immediately, and badly.
What the hotelier is liable for
The Italian Civil Code places liability on the hotelier for items guests bring onto the property, capped at a hundred times the daily room rate. That cap disappears, and liability becomes full, when the items have been formally handed over for safekeeping, or when the property refused to take them into safekeeping despite being able to. An in-room safe doesn’t count as handing something over for safekeeping: it remains a service offered to the guest, who uses it with their own code.
Two practical consequences follow. The first is that a sign in the room reading “management is not responsible for items left in the room” has no exempting effect, because a clause like that cannot override the rules on hotelier liability. The second is that the safekeeping service at reception needs to be kept active and made known, because that’s what lets a guest formally deposit valuable items. These sit within the wider set of obligations placed on whoever manages a hospitality property, and it’s worth clarifying them with your own adviser before opening, not after the first dispute.
On the insurance side, almost all hotel policies cover theft of valuables from the safe with a dedicated limit, typically between €1,000 and €5,000 per room, and they require the safe to be anchored. An installation simply resting on a shelf voids the cover.
Maintenance and spare parts
Motorised door, hinges, keypad: three components that wear out. The silicone rubber keypad wears through after roughly 15,000 presses, that’s four or five years in a heavily booked room. Check that the supplier guarantees spare parts availability for at least eight years, following the same logic as keeping a stock of spare parts and finishes for the furniture: a discontinued safe has to be replaced entirely, with new drilling and repair work to the unit.
A useful check every six months: open every safe with the master code, check the battery level on the display, and make sure the door closes again without forcing it. A technician takes three minutes per room.
Frequently asked questions
Is an in-room safe a legal requirement?
There’s no national requirement covering every property. Many regional classification regulations require one from four stars upward, allowing a reception safekeeping service as an alternative. The reference to check is your own region’s regulation.
What internal size do you need for a 17-inch laptop?
At least 45 cm of width and 35 cm of depth, measured with the door open and net of the door stops. If you want the padded sleeve to fit too, you need 50 cm of width. The external dimensions stated in catalogues aren’t enough to work this out.
If a guest says their safe was emptied, how do I protect myself?
The electronic access log is the main tool: it shows the date, time and type of code used for every access. It has to be extracted straight away, before any reset of the device, and kept safe. You then need a police report and to involve the insurance company within the policy’s deadlines.
Is it better battery-powered or connected to the mains?
Mains power with a backup battery, if the socket can be planned at the electrical design stage. Battery-only works fine but requires a scheduled replacement plan, because a flat safe at night with documents and flight tickets inside becomes a serious problem within minutes.
How much does it cost to install one in an already-fitted wardrobe?
Between €40 and €80 per room in labour, if the shelf can take the load and the wall behind it is masonry. On plasterboard walls you need reinforcement, and the cost doubles. Planning the compartment at the wardrobe design stage removes this cost altogether.
