Both need roughly the same footprint, so the real question usually isn't which one fits, it's whether your existing pipework leaves enough depth for an integrated model's cabinet door.

What are the dimensions of freestanding vs integrated dishwashers?
Both types are typically around 60cm wide (slimline models run around 45cm) and roughly 82cm tall, fitting neatly beneath a standard worktop.
The main difference is depth. Freestanding dishwashers sit with the top level with your worktop, so they're generally deeper (around 59.8cm), while integrated models need extra space at the front for a cabinet door. This gives them a shallower standard depth of around 55cm.
How do I know if a dishwasher will fit my space?
Measure width, height, and depth of the available space. Don't push the measurement flush to the back wall. Allow at least 3cm behind the dishwasher for the water supply and drain pipes.
Do I need to install an integrated or freestanding dishwasher?
Most of the time, either works, since both need a similar amount of space overall. The deciding factor is usually existing pipework: if there's pipework running more than 150mm off the floor at the back of the space, an integrated dishwasher likely won't sit far enough back to work properly. In that case, a freestanding model, or having the pipework moved, is the better route.
If there's nothing in the way above 150mm off the floor, the choice is genuinely yours.

What do you need to install a dishwasher?
Both types need to be near a power connection and your kitchen's water supply, connected to your plumbing. If these are already in place, installation is simply a case of plumbing the unit in (plus fitting the cabinet door, for integrated models). If not, you'll also need:
An electrician to run a new feed from another socket
A plumber to add the appropriate connection under the sink

What does dishwasher installation involve?
Assuming pipework and power are already in place, installation is usually straightforward, though we'd still recommend a dishwasher technician or plumber for a safe, leak-free result. The process typically involves:
Unboxing the new appliance and checking for damage
Inspecting existing electrical and plumbing connections for safety and suitability
Turning off water at the mains
Connecting to the mains water supply (within 1.5m of the appliance) and electrical socket
Connecting the waste hose to a downpipe or extended waste connection
Testing for leaks and functionality
Turning water and power back on
Removing the old dishwasher, if agreed beforehand
Integrated installations generally take a little longer, since the cabinet door needs fitting and aligning with the rest of your kitchen.
Dishwasher installation cost guide
Even the most straightforward dishwasher installations may require help from the professionals. Just in case, we recommend factoring this into your calculations when budgeting for dishwasher installation costs.
How much does dishwasher installation cost?
Costs for integrated and freestanding installation are broadly similar, though freestanding can work out slightly cheaper, since there's no cabinet door to fit and align. Repair costs also tend to run a little lower for freestanding models, since they're generally easier to access. Our dishwasher installation cost guide has current pricing for both.
What's better: an integrated or freestanding dishwasher?
There's no single right answer; it comes down to your priorities.
Integrated pros: hidden from view; slick, uniform kitchen look; generally quieter; no gaps for crumbs and dirt; can support your home's resale value.
Freestanding pros: more affordable; easier to install; cheaper to repair; can be taken with you if you move house; matches easily with other freestanding appliances; wider choice available.

FAQs
Yes, though you'll likely need to remove or adjust the kitchen plinth to accommodate the change.
Generally more expensive, slightly longer to install, marginally higher repair costs, can't be taken with you if you move, and offers less model choice than freestanding.
Yes, they need the same drainage point and water connection as an integrated model.
Roughly 60cm wide, 82cm tall, and 59.8cm deep, plus 3cm clearance at the back for pipework.
If the drainage, water, and power connections already exist, it's mainly a case of connecting it up. We'd still recommend a professional, since incorrect installation raises the risk of leaks and water damage.
