The short answer
A built-in dishwasher is installed under the worktop or counter and fixed into the kitchen, often alongside cabinets. A freestanding dishwasher is a self-contained unit with a finished top and sides, so it can stand on its own and be moved or taken with you. Many freestanding models can also be slotted under a counter, so the practical difference is often about finish, fixing and flexibility.
What a freestanding dishwasher is
- It has finished sides, top and front in a colour such as white, black, silver or stainless steel.
- It is not tied to cabinetry, though it still needs water, drainage and power.
- It is usually easier to replace or take when you move home.
- The visible front means it does not blend away with your kitchen.
What a built-in dishwasher is
Built-in dishwashers are fitted in a gap in the kitchen and designed to look part of it. Styles include:
- Fully integrated: the control panel is on the top edge of the door and a matching cabinet door covers the front, so it is hidden when closed.
- Semi-integrated: a cabinet door covers most of the front, but the controls remain visible.
- Front-control built-in: the machine has its own visible front, typically stainless steel or colour finish, and sits under the counter.
Each style is usually fixed to the surrounding cabinets or worktop, which makes it harder to move.
Types of dishwasher
When people ask what types exist, the common groupings are:
- Freestanding: stands alone, finished all round.
- Fully integrated: hidden behind a cabinet door.
- Semi-integrated: controls visible, door panel covering the rest.
- Slimline or compact: narrower or smaller versions of the above.
- Portable or countertop: a smaller machine that is moved and connected to a tap or sink when used.
Side-by-side comparison
| Feature | Freestanding | Built-in |
|---|---|---|
| Look | Visible finished appliance | Blends with cabinets (fully integrated) |
| Fixing | Not fixed to cabinets, though it may be secured | Fixed to cabinets or worktop |
| Moving house | Easy to take or replace | Normally left in place |
| Controls | Usually on the front | May be on top of the door |
| Door weight | Standard door | Door carries a cabinet panel |
| Fitting | Simpler | More involved |
Sizes vary by market. Typical dishwasher widths include 60 cm and slimline widths of about 45 cm. One retailer guide gives integrated dishwashers as roughly 81 to 85 cm high, 54 to 57 cm deep and 58 to 60 cm wide, with extra room needed at the back for pipework. Always confirm the exact dimensions in the installation manual.
Can you put a freestanding dishwasher in an integrated space?
Often yes, if the dimensions fit. Many freestanding dishwashers are made at heights that allow them to slide under a worktop. Points to check:
- The height, width and depth against the gap, with clearance for hoses.
- Whether the machine’s top and sides are suited to being enclosed, as the manufacturer allows.
- That the unit has adjustable feet so it can sit level.
- Whether the front will look odd next to your cabinets.
- That nothing blocks the door from opening.
Going the other way, an integrated machine is not normally meant to stand alone, since it lacks finished sides and a front. Check the manual for the manufacturer’s instructions.
Built-in versus portable
A portable dishwasher is on wheels and connects to a tap and sink for each use, so it suits renters and kitchens with no plumbing provision. A built-in dishwasher has a permanent water supply, drain and power connection. Portable machines are generally smaller and less convenient for daily use.
Installation and safety
Dishwashers combine water and mains electricity, so installation should be careful.
- Fit the machine only to a properly installed water supply, drain and electrical outlet.
- Use an isolation valve so water can be shut off.
- Ensure the appliance is earthed and the socket is accessible and suitable.
- Have a qualified plumber or electrician handle new connections or socket changes.
- Switch off power and water before sliding the machine out or working behind it.
Repair and servicing differences
Freestanding machines are generally easier to pull out and service. Integrated ones may need the door panel removed or the unit unfastened from cabinetry, and heavy panels can cause door spring and hinge wear. If you suspect a fault, see our guide to integrated dishwasher problems and failing parts.

How to choose
Choose freestanding if you rent, may move, or want a simple swap. Choose built-in if you have a fitted kitchen and like a uniform look. Choose fully integrated if you want the machine hidden, and accept that fitting and repairs may be more involved.
Frequently asked questions
What types of dishwashers are there?
Freestanding, fully integrated, semi-integrated, slimline or compact, and portable.
Can you put a freestanding dishwasher in an integrated space?
Often, if the size fits and the manufacturer allows it, but check measurements and clearances first.
What is meant by a built-in dishwasher?
One installed under the worktop and fixed in place, designed to blend with cabinets.
What’s the difference between a built-in dishwasher and a portable one?
A built-in has permanent water, drain and power connections and is fixed in place. A portable is mobile and connects to a tap and sink when in use.
