Student without a dedicated water supply
If your studio flat doesn’t have a usable fixed water connection, consider models with a water tank. You’ll still need to fill the tank and have a practical route for draining the wastewater.
Who are these options suitable for?
Tenant with a sink and accessible connections
If your kitchen’s water supply and drainage are compatible, a plumbed-in countertop model could save you filling it by hand. Check the available space and electrical installation too.
Tenant whose installation would require alterations
Before making changes to your home’s fittings, check your tenancy agreement and building rules. ANIL notes that alterations to rented premises or equipment require the landlord’s written consent.
What should you check before choosing?
Model with a water tank
Consider this if: you don’t have a usable fixed water supply, but can drain the water after every cycle.
Bear in mind: you’ll need to fill it by hand, and should compare its capacity with the amount of washing up you do. Daan Tech says Bob has a water tank and a stated capacity of 3 place settings.
Plumbed-in countertop model
Consider this if: suitable water and drainage connections and a suitable space are already available.
Bear in mind: it depends on your home’s plumbing. Candy says the CP 6E51LS holds 6 place settings, but check that its dimensions and installation requirements suit your kitchen.
Washing up by hand
Choose this if: you can’t arrange drainage, an electrical supply or a suitable space without making unauthorised alterations.
Bear in mind: this option won’t wash your dishes automatically, but it can be a temporary solution while you check what installation options are available.
| Factor | What to check | Who should consider it? |
|---|---|---|
| Water and electricity | Check for a usable drain, then make sure the model’s water supply requirements and electrical supply are suitable. Promotelec says a dishwasher socket must be on a dedicated circuit. | Without a dedicated water supply, I need to be able to fill the appliance and drain the water without an improvised installation. Around 42% of consumers prioritise whether the appliance can be installed at all. |
| Space and capacity | Measure the available surface and check that the door can open; compare the stated capacity with your plates and saucepans. | With a small worktop, I want an appliance that leaves room to work without ruling out the dishes I use. This is the main consideration for around 33% of consumers. |
| Rental rules | Check your tenancy agreement and building rules. If the project involves altering the rented premises or equipment, ask the landlord for written consent, as ANIL advises. | If installing the appliance means altering the studio’s fittings, I want to check what’s allowed before taking action. This comes first for around 25% of consumers. |
Mistakes to avoid
-
Assuming a water tank means you won’t need to drain the water
A water tank replaces a fixed water supply, not wastewater drainage. Daan Tech says Bob has a 1.50 m drain hose that should lead to a sink or another suitable drainage point.
Before buying, work out where the water will go during a cycle and make sure the hose can reach.
-
Relying on the word “compact” alone
Daan Tech states that Bob measures 34 × 49 × 49 cm and holds 3 standard place settings; Candy says the CP 6E51LS measures 550 × 501 × 443 mm and holds 6 place settings. Their capacities and size make them suitable for different needs.
Measure the space with the door open, and compare the stated capacity with your largest dishes.
-
Altering the kitchen without checking the rental rules
Work on the plumbing, a cupboard or the electrics may count as an alteration to rented equipment. ANIL notes that the landlord’s written consent is needed for such alterations.
Check your tenancy agreement and building rules, then get the required consent before doing any work.
Depending on the circumstances, you may be asked to put things back as they were if you make alterations without consent.
-
Making do with an improvised electrical supply
When choosing a spot near the sink, you also need to consider the electrical installation. Promotelec says a dishwasher socket must be on a dedicated circuit.
Check the existing supply before choosing where to put the appliance. If alterations are needed, discuss them with the landlord and a qualified professional.

Frequently asked questions
Can a mini dishwasher with a water tank work without a water supply in a studio flat?
Yes, if the model has an integrated water tank and you can fill it as described in the instructions. You’ll also need to drain the wastewater: Daan Tech, for example, says Bob’s hose must lead to a sink or another drainage system.
Do you need to fill a plumbed-in countertop dishwasher?
A model connected directly to a water supply doesn’t need you to fill a tank by hand for each cycle. That’s the setup Candy specifies for the CP 6E51LS. Check that your studio flat’s water supply and drainage are suitable.
Can I alter the plumbing in a rented home?
If the work involves altering the rented premises or equipment, first ask the landlord for written consent, in line with the guidance from ANIL. Check your tenancy agreement and building rules before planning any work too.
What electrical supply does a dishwasher need?
Promotelec says a dishwasher socket must be on a dedicated circuit. In an existing studio flat, check the available installation before buying. Discuss any necessary alterations with your landlord and, if needed, a qualified professional.
