**The short answer**

Open shelving is cheaper per metre, shows you everything and dries out after a damp winter. Cabinets hide the mess, lock away chemicals and tools, and keep dust off, but a closed steel cabinet in an unheated garage sweats on the inside, and you pay more for less shelf. Open for the workshop, closed for what must be locked.

## You are choosing between seeing and hiding

Open shelving shows you everything you own, all the time. That is its strength — you find things by eye, and you notice what you are out of — and it is also the reason a garage full of open shelving looks like a garage full of stuff, because it is. A cabinet hides the same stuff behind a door, which is why a garage with cabinets photographs well, and why the top of every cabinet in it ends up covered in the things that did not fit inside.

The honest version of the choice is about what happens to the things you use. On an open shelf a tin goes back where it came from because putting it back is one movement. In a cabinet it is two movements and a door, and it ends up on the bench. Cabinets suit what you store; shelving suits what you use. Most garages have both kinds of thing, and the split is worth making before anything is bought.


## Cost per shelf, and what the door is actually for

Open shelving is cheaper per shelf by a distance, because a shelf is all you are paying for. A five-tier boltless steel unit gives you five long shelves for the price of the steel, and a wall-hung four-tier shelf gives you four shallow ones above a bench for less again. A cabinet is a shelf or two plus a carcass, a door, hinges and a lock, and you pay for all of it. The same money buys far more open shelf than closed, and it always will.

What the door buys is three things: dust stays off, mess stays out of sight, and the contents can be locked. Only the third is something shelving cannot do at all. Dust on an open shelf is real, but a lidded box handles it; mess is a habit rather than a hardware problem. Locking is different. Fuel, solvents, sharp tools and anything a child should not reach belong behind a door with a key, and that is where a cabinet earns its price.

| Axis | Open shelving | Cabinet |
| --- | --- | --- |
| Cost per shelf | Low | High; you pay for the door |
| Finding things | By eye, at a glance | Open the door, remember what is where |
| Putting things back | One movement | Two movements and a door |
| Dust | Settles on everything | Mostly kept out |
| Damp garage | Air moves; dries after winter | Cold steel box; condensation inside |
| Locking | Not possible | Yes, and the main reason to buy one |
| Looks | Honest | Tidy, until the top gets used |


## What a closed steel cabinet does in an unheated garage

Warm, moist air condenses on cold surfaces, and in a British garage the coldest surface in January is the inside of a steel cabinet. The air inside is the same damp air as the rest of the room; the steel is cold; and with the door shut there is no airflow to dry anything out. So tools in a closed cabinet in a damp garage can rust faster than tools on an open shelf in the same room, which is the opposite of what the cabinet was bought for.

That is not an argument against cabinets, it is an argument for knowing what they are. A cabinet in an integral garage sharing a wall with a heated house is fine. A cabinet in a detached single-skin garage wants something absorbing moisture inside it, the door cracked in winter, and nothing precious in it that cannot be oiled. Open shelving does not have the problem, because air moves across it and a damp shelf dries out in spring.


## What genuinely needs a door

A short list. Fuel, solvents and anything flammable, which should be behind a door that shuts and out of reach of anyone who does not know what it is. Sharp tools and blades if there are children in the house. Anything valuable and portable if the garage door is a weak point, which most up-and-over doors are. Chemicals that stain or attack what they touch. Everything else — tins, boxes, kit, tools — is an argument about tidiness, and tidiness is cheaper to solve with boxes on shelves than with doors.

The middle way is a lidded box on an open shelf. It keeps dust off, it hides the contents, it comes off the shelf whole and goes to the job, and it is a fraction of the cost of a cabinet with the same volume. For small parts, a clear-fronted drawer cabinet that stands on the bench or hangs on the wall is the same idea shrunk: closed enough to keep the dust off, open enough to see what is in it without opening anything.


## Who should pick which

Pick open shelving if the garage is a workshop, if it is damp, if the money has to go a long way, or if you know yourself well enough to admit that things behind a door will end up on the bench. A boltless unit for the weight and the boxes, a shallow wall shelf above the bench for what you reach for. Add lidded boxes for the dusty things and write on the front of everything.

Pick cabinets if there are things that must be locked, if the garage is also a room you show people, or if it is integral, dry and warm enough that condensation inside a steel box is not a worry. Buy fewer than you think. One lockable cabinet for the dangerous things and shelving for everything else is the usual right answer, and it is a long way cheaper than a wall of doors that mostly hide tins.

## Common questions

**Are cabinets or shelves better for a garage?**

Shelves for most things, a cabinet for the few that must be locked. Open shelving costs less per shelf, shows you what you have, and dries out in a damp garage; a cabinet hides mess and keeps dust off, but a closed steel cabinet in an unheated garage sweats inside. One lockable cabinet plus shelving suits most garages.

**Do tools rust in a metal garage cabinet?**

They can, and sometimes faster than on an open shelf. The air inside the cabinet is the same damp air as the garage, the steel is cold, and with the door shut nothing dries. In a detached, unheated garage keep something absorbing moisture inside, crack the door in winter, and oil anything that matters. An integral garage sharing a wall with the house is far less of a problem.

**What should be locked away in a garage?**

Fuel, solvents and anything flammable; blades and sharp tools if there are children; anything portable and valuable if the garage door is easy to force, which most up-and-over doors are; and chemicals that stain or attack what they touch. Everything else is a tidiness question, and lidded boxes on shelves solve tidiness for less than cabinets do.

**How do I keep dust off open garage shelving?**

Put the things that mind dust in lidded boxes on the shelf and leave the rest in the open. A box comes off the shelf whole and goes to the job, keeps dust and damp off, and costs a fraction of a cabinet with the same volume. Keep the floor swept, because most garage dust starts on the slab.
