Renters without a dedicated water supply
You’d like to cut down on washing up by hand without immediately arranging plumbing work. A water tank can solve the water supply issue, provided you also have a suitable way to drain the wastewater.
In a rented home with no dedicated plumbing connection, a dishwasher with a water tank can remove the need for a fixed water supply, but you’ll still need a safe way to fill the appliance and drain the wastewater. A model that needs plumbing connections is only an option once you’ve checked the installation. If the work would alter the property or its fittings, you’ll also need the landlord’s written consent, as ANIL points out. If you can’t confirm a suitable space and drainage point, it’s best to hold off buying.
You’d like to cut down on washing up by hand without immediately arranging plumbing work. A water tank can solve the water supply issue, provided you also have a suitable way to drain the wastewater.
You’re looking for a capacity that suits your routine. Before considering a plumbed-in appliance, check the water supply, drainage, available space and any conditions that apply to your rented home.
If you’re unsure whether you have a stable surface, a suitable socket or somewhere to drain the wastewater, start by checking these points. They’ll determine whether you can install an appliance without improvising any alterations.
In a rented home with no obvious dedicated plumbing connection, drainage and placement matter more than the appliance format: a water tank alone won’t take care of the whole installation.
Consider it: if you can fill it manually, position it and arrange drainage in line with the instructions, without a fixed water supply.
Bear in mind: you’ll need to fill the tank and deal with the wastewater every time you use it.
Consider it: if you’ve confirmed that the water supply, drainage and space required for the model are all available.
Bear in mind: installation depends on those plumbing connections. If any alterations are needed, you’ll have to contact your landlord first.
Best if: you can’t confirm the drainage, socket, supporting surface or conditions for carrying out work in the property.
Bear in mind: you’ll need to keep washing up by hand for now while you clarify what installation is possible.
| What to consider | What to check | Who is it for? |
|---|---|---|
| Water supply and drainage | How the model is filled; where the drain hose goes and how it is secured, as set out in the instructions. | I don’t have a dedicated water supply and want to avoid a fixed connection, without finding out after buying that there’s nowhere for the wastewater to go. Around 38% of consumers would put the option of installing a model without a fixed water supply first. |
| Space and capacity | Dimensions, required clearances and place-setting capacity, considered alongside the items you use. | In a small kitchen, I need to be able to position the appliance without giving up the space I need for my usual washing-up. For around 25% of consumers, size and capacity would be the top priority. |
| Regular use | Whether the required plumbing connections are actually available and what conditions apply to any work in the property. | If I have more washing-up to do, I’d rather consider a plumbed-in model than refill a tank each time. Ease of use would come first for around 25% of consumers. |
| Installation feasibility | A stable, dry surface, a suitable socket and no unapproved alterations. | I don’t want to order an appliance before I know where it can go and how to use it without improvising an installation. Around 12% of consumers would be most concerned with checking that installation is possible before buying. |
A water tank removes the need for a fixed water supply on models that have one, but the wastewater still needs to be drained. Daan Tech’s Bob, for example, comes with a drain hose.
Find a suitable drainage point before you buy, then check the instructions for the hose length, positioning and how to secure it on your chosen model.
Adding a new plumbing connection may involve work on the property. ANIL points out that alterations to rented premises or fittings require the landlord’s written consent; whether a particular project counts as an alteration depends on what it involves.
Check your tenancy agreement and inventory, explain the proposed work to your landlord and get a written response before arranging it.
A countertop appliance still needs a suitable surface. Its stated place-setting capacity may also not suit the pans and other items you want to wash.
Measure the space and clearances required in the instructions, then compare the stated capacity with your usual washing-up.
Altering an installation or using a damaged appliance to make it fit can create a hazard. INRS points out that working on electrical equipment carries risks.
Follow the manufacturer’s instructions for connecting the appliance, and ask a competent person to check any installation or repair issues.
The Bob is an example of a small countertop dishwasher that can be filled from a water tank.
The CDWMTO201D(W) is an example of a tank-fed countertop model to consider for a small amount of washing-up.
Bosch compact models offer a point of comparison if you can confirm that the necessary plumbing connections are available.
These two tank-fed countertop models are options if you want an appliance that doesn’t need a fixed water supply. You’ll still need a suitable surface, a socket that meets the instructions and a way to drain the water in your home.

It depends on the work involved, so don’t assume it’s allowed. ANIL points out that alterations to rented premises or fittings require the landlord’s written consent. Check your tenancy agreement and inventory, then explain the project clearly to your landlord before arranging any work.
No. The tank supplies water; it doesn’t get rid of the wastewater. Daan Tech says its Bob can be filled from a tank, but it still comes with a drain hose. Before choosing a model, check where the water can drain and how the hose should be positioned.
Check the dimensions and clearances required by the manufacturer, then make sure the surface is stable and dry and that there’s a suitable socket nearby. Follow the model’s instructions; INRS highlights the risks of working on electrical equipment.
