Can a bar cart hold a microwave?

Yes, on the top shelf of a cart rated for it — and the BON AUGURE BNG-BC1841-V is the only cart in this registry that can also take one on a middle shelf, because it is the only one that publishes a big enough shelf gap AND a per-shelf load rating to put an appliance on. Four other carts here will hold a compact microwave on top. Almost nothing on the market will hold one underneath another shelf.

The number that decides it is not the weight. A GE 0.7 cubic foot countertop microwave publishes 21 lb, which any cart on this page carries without argument. What that same listing also publishes is the clearance requirement: three inches on each side and above, one inch at the rear, and the bottom fully unobstructed. The appliance is 17.31 inches wide, 12.75 deep and 10.19 high.

Add the clearances and the cart has to give you 23.31 inches of usable width, 13.75 inches of depth, and 13.19 inches of vertical space above the shelf. That last figure is the one that kills it. This site has already measured what carts publish for shelf gaps on the shelf gap page: the common figures are 8.5 and 13 inches. Both are less than 13.19, which means a microwave on a three-tier cart goes on the top shelf or nowhere.

The arithmetic, in one table

A larger microwave moves every row the wrong way. A GE Profile 1.1 cubic foot model publishes 24 inches of width, 12.875 of depth and 29 lb, which with side clearance needs 30 inches of usable shelf width — wider than most bar carts are in total.

What I compared them on

Depth, against 13.75 inches. The hard floor. This is where most of the category fails: the shallow carts this site recommends for hallways and dining walls are 11 to 13 inches deep, and an appliance overhanging the back of a cart has nothing supporting its rear feet.

A per-shelf load rating, not a whole-cart total. 21 lb in one spot that never moves is a different load from 21 lb of bottles spread across a shelf. Two carts here publish a real per-shelf figure; one publishes a whole-cart number, and two publish nothing — which is explained on weight capacity.

A published shelf gap. Seven carts in this registry publish one and six of those figures clear 13.19 inches. What separates them is what else they publish: only the BON AUGURE pairs a big enough gap with a per-shelf load rating, and the section below works through the other five.

Whether the surface tolerates heat and steam. A microwave vents warm, damp air, and what it vents onto matters. Glass and coated metal do not care. Board does, and the carts that publish "Wipe with Dry Cloth" as their care instruction are telling you how they feel about moisture — the same evidence the bathroom page is built on.

The five, compared on published figures

The five, and who each is for

The pick (BON AUGURE BNG-BC1841-V). Best for a microwave that is not on the top shelf. 150 lb per shelf on all three, 37.01 inches of width, 14.17 inches of depth, and the figure that makes it the only real answer here: a published 16.3 inches between the middle shelf and the bottom one. 16.3 clears the 13.19 a compact microwave needs with three inches to spare, which means the appliance can live on the bottom shelf with the serving surface left free above it. Five other carts in this registry publish a gap that clears 13.19 inches — the bali & pari Lombok at 18.5 and Selah at 15.6, the Zhori at 14, the FATORRI at 13.5, the HMYHUM 01018 and Dethan at 13.4 — and not one of them publishes a per-shelf load figure to go with it, which is what you need before an appliance goes under a shelf. It is reviewed in full at BNG-BC1841-V. Against it: 14.17 inches of depth clears 13.75 by less than half an inch, so the appliance sits nearly flush with the back; the shelves are MDF and the listing publishes "Wipe with Dry Cloth", which is a reason to keep the vent away from the surface; and 39.79 lb empty makes it a two-person move.

The strongest shelf (PETKABOO HSC123WF). Best for the heaviest appliance on the top shelf. A published 110 lb on the top shelf, 90 on the middle and 110 on the bottom — stated per shelf, which is the honest way — on a 44.49 by 14.3 inch solid-wood frame. 44.49 inches of length means the microwave takes up a third of the shelf and leaves a genuine working surface beside it, which is the practical difference between a cart with an appliance on it and a cart that is an appliance stand. It is reviewed at HSC123WF. It publishes no shelf gap, so the appliance goes on top; 42.2 lb empty plus an appliance is a cart that stops being mobile; and solid wood at this price means a rustic finish that will mark where a hot vent sits against it.

The best clearance margin (Aubtik AU-BC208-W). Best for a deeper or larger microwave. 16.81 inches of depth is the deepest cart on this page and the only one with real margin over the 13.75 minimum — three inches of it, which is what you want if the appliance is a 1.1 cubic foot model rather than a 0.7. 35.43 inches of width, wrap-around rods on every shelf and a push handle. Its published capacity is a whole-cart figure rather than a per-shelf one, and the listing has said both 300 lb and 290 lb at different times this year, so treat it as indicative. The shelves are MDF with a dry-cloth care instruction, and 36.06 inches of height puts a microwave door at an awkward reach for a shorter cook.

The wipeable one (VEVOR SS-4). Best for a surface that tolerates what a microwave vents. Three tempered glass shelves on a powder-coated iron frame at a published 44 lb per shelf, 34.64 inches wide and 14.96 deep. Glass is the right surface under an appliance that vents warm damp air, because unlike board it has nothing to absorb and nothing to lift — and 44 lb is double the GE's 21 without being a figure you have to guess at. Against it: 37.04 lb is heavy for its size, two of four wheels lock rather than four, and glass under a vibrating appliance will transmit the noise rather than damp it.

The one that advertises the job (SWTYMIKI ZWJ320). Best for the storage a microwave displaces, not for the microwave. Its own listing calls it a microwave storage station, and at 20.47 inches of width it cannot give a 17.31-inch appliance the three inches each side its manufacturer asks for — it gives about 1.6. It is on this page because it solves the other half of the problem well: an open top, a real drawer and a mesh-door cabinet take the plates, the cups and the packets that a microwave needs next to it, with four casters and two locks. It publishes no load rating anywhere, it is 18.92 lb and therefore light under a 21 lb appliance, and the width means a microwave on it will overhang its own clearance.

Why the clearance matters more than the weight

A microwave cooks by putting energy into food and the cabinet gets rid of the waste heat through side and rear vents. Block them and the magnetron runs hotter than designed; it does not fail dramatically, it fails early.

That is why the manufacturer publishes a number rather than a suggestion, and it is why the three inches above matters most on a cart specifically. A countertop microwave under a kitchen cabinet has a whole kitchen of air to dump heat into. The same appliance in the middle bay of a three-tier cart has a shelf eight and a half inches above it and bottles on either side, which is a box.

Two practical consequences. First, if the cart has three tiers and no published gap, the microwave goes on top — where there is no shelf above it at all, and the clearance question reduces to the sides. Second, do not fill the shelf beside it: a row of bottles against the vent side is the same obstruction a cabinet wall would be, and bottles are the thing a bar cart is otherwise for.

The honest answer for most kitchens

If what you need is a permanent home for a microwave, a bar cart is a compromise and a kitchen cart is the right object. The reason is not strength, it is that the microwave stops the cart being a cart.

An appliance on a shelf cannot be unplugged every time the cart moves, so the cart stops moving — and a cart that does not move is a worse piece of furniture than a fixed unit of the same size, because it has no doors and no drawers and it rolls when you lean on it. The mobility is the only thing you were paying for. Carts with closed storage, which are the ones that cope best with this, are on enclosed carts, and the sideboard version of the argument is on bar cart or sideboard.

Where a cart genuinely wins is the temporary or dual-use case: a rented kitchen with no counter to spare, a garden room, a studio, a coffee station that also has to reheat something. In those rooms the microwave is one of two or three jobs the cart does, and the right buy is a published per-shelf rating and the deepest shelf you can fit. If the job is coffee rather than cooking, the setup is on the coffee cart page, and the weight and steam problems are the same ones the no-alcohol cart works through.

Before you order

Measure your microwave rather than trusting a capacity figure — cubic feet describes the cavity, not the cabinet, and two 0.7 cubic foot models can differ by two inches of width. Then add three inches to each side, one to the rear and three above, and compare that to the cart.

Then decide which shelf it will live on. If it is the top shelf, you need width and a per-shelf rating and nothing else. If it has to go underneath another shelf, you need a published gap of at least 13.19 inches for a compact model, and in this registry exactly one cart publishes one.

And check where the socket is before you buy the cart, because the cable decides the placement. An appliance cable over a shelf edge on a wheeled object is the one failure on this page that is genuinely dangerous rather than merely disappointing.
