↓ See why we picked itFor a rental, an older home, or any kitchen that was never built with a dishwasher line, the deciding factor isn't which machine washes best, it's which one requires zero plumbing modification at all. These four machines run entirely on a built-in tank you fill from any sink faucet, with wastewater collected in a separate compartment you empty afterward, meaning no plumber, no drilled cabinet holes, and nothing that isn't fully reversible if you move out.
This is a genuinely different category from a standard under-counter dishwasher or even a rolling faucet-adapter portable model, both of which still need some connection to your plumbing. The four picks here need literally none, just access to a sink for filling and emptying.
6 Criteria to Look For Before Buying a Countertop Dishwashers Without Plumbing (2026)
Key buying criteria so you get the right fit the first time.
Zero plumbing modification across every pick
All four machines in this guide require absolutely no plumbing installation, cabinet drilling, or permanent connection of any kind. They rely entirely on a built-in tank filled from a sink faucet and a wastewater compartment emptied after each cycle.
This differs from a rolling faucet-adapter portable dishwasher
A different category of "portable" dishwasher connects temporarily to your kitchen faucet via an adapter hose each time you use it. The machines in this specific guide need no faucet connection at all, just manual filling from any sink, a more complete no-plumbing solution.
Reversibility matters for renters specifically
Since none of these machines modify your kitchen in any way, you can take them with you when you move, a genuine advantage for renters compared to even a minimal-installation dishwasher alternative.
Verified noise ratings vary across no-plumbing options
Only the EUHOMY in this guide carries a specific 40dB rating. In a rental with shared walls or noise-sensitive neighbors, that verified number is worth prioritizing.
App control adds convenience but also complexity
The Silonn's app control lets you monitor cycles remotely, but it also adds a dependency on app connectivity and updates that a purely on-machine-controlled option like the HAVA doesn't have.
Place-setting capacity varies even within this no-plumbing category
The COMFEE's verified 6-place-setting rating is larger than the Silonn's 4, a real consideration for renters with more than one or two people's daily dishes.

Silonn Portable Countertop Dishwasher with App Control, 5L Tank, 8 Programs
About this pick
This Silonn adds app control to the standard no-plumbing formula, letting you start or monitor a cycle remotely, a smart-appliance feature not found on the more basic EUHOMY or COMFEE machines in this comparison. Its 8-program menu and 5-liter tank are both solidly mid-to-large for this no-plumbing category.
Its 4-place-setting rating is more modest than some 6-place-setting competitors, reflecting a slightly smaller wash chamber in exchange for the smart connectivity feature. Like every machine here, it requires zero plumbing connection, just a sink nearby for filling and draining.
For renters who want the reassurance of app-based monitoring without needing to be in the kitchen when a cycle finishes, alongside the core no-plumbing convenience, this is the strongest overall pick in this comparison.
Best for: Renters who want app-based monitoring alongside zero-plumbing convenience

EUHOMY Countertop Dishwasher Portable, 8 Programs with 5L Tank, Black, 40dB
About this pick
This EUHOMY matches the Silonn's 8-program count and 5-liter tank while adding a specifically verified 40-decibel noise rating, a genuine advantage in a rental where noise complaints from neighbors or roommates could be a real concern. It skips app connectivity in favor of straightforward on-machine controls.
Its price is close to the Silonn's, so the choice between the two mainly comes down to whether app control or a verified noise rating matters more to your specific rental situation. Like every pick here, it requires zero plumbing installation.
For renters who prioritize confirmed quiet operation over smart connectivity, particularly in a shared or noise-sensitive living situation, this EUHOMY is the pick over the Silonn.

COMFEE' Countertop Dishwasher, Energy Star, 6 Place Settings & 8 Washing Programs
About this pick
This COMFEE offers the largest verified place-setting capacity in this comparison at 6, ahead of the Silonn's 4, along with Energy Star certification the other picks here don't explicitly carry. For a renter with a slightly larger household, this capacity difference is a genuine practical advantage.
It's the highest-priced pick in this comparison, reflecting both the larger rated capacity and the certification. Like the rest of this guide, it needs zero plumbing connection, relying entirely on its built-in tank.
For renters who specifically need more capacity than the Silonn or EUHOMY offer, and value a verified Energy Star certification, this COMFEE is worth the price premium in this comparison.
Best for: Renters with slightly larger households who want verified capacity and certification

- Place settings: 6
- Certification: Energy Star
Pros
- +Largest place-setting rating in this comparison at 6
- +Energy Star certified
- +Zero plumbing installation required
Cons

HAVA Countertop Dishwasher, 6 Programs Portable Dishwasher with Water Tank
About this pick
This HAVA keeps to a simpler 6-program menu than the other picks here, without app control, a verified noise rating, or Energy Star certification, but it covers the core no-plumbing dishwasher need at a reasonable price. For a renter whose main goal is simply avoiding a plumbing installation without needing the extra verified specs of the pricier options, this is a straightforward choice.
Its built-in tank and manual fill-and-drain routine work identically to every machine in this guide. Without the Silonn's smart features, the EUHOMY's verified quiet rating, or the COMFEE's certification and larger capacity, it's positioned as the more basic option in this specific comparison.
For renters comparing mainly on price and core no-plumbing functionality rather than any single standout verified spec, this HAVA is a reasonable choice.

Frequently Asked Questions
Do any of these dishwashers require even a temporary plumbing connection?
No. All four machines in this guide use a built-in tank you fill manually from any sink faucet and a wastewater compartment you empty after each cycle, requiring absolutely no plumbing connection, not even a temporary faucet adapter.
How is this different from a portable dishwasher that connects to my faucet?
A faucet-adapter portable dishwasher connects temporarily to your kitchen faucet via a hose each time you use it, meaning it still requires a compatible faucet and a hookup process. The machines in this guide need no faucet connection at all, just manual filling from any sink.
Can I take one of these dishwashers with me when I move?
Yes, that's one of the main advantages of this category. Since none of these machines modify your kitchen or require plumbing installation, you can pack them up and take them to your next home just like any other appliance.
Which no-plumbing dishwasher is quietest?
The EUHOMY in this guide is the only pick with a specific, verified 40 decibel noise rating, useful information for a rental with shared walls or noise-sensitive neighbors.
Is app control worth it on a countertop dishwasher?
It depends on your preference. The Silonn's app control lets you monitor and start cycles remotely, a genuine convenience, but it also adds a dependency on app connectivity that a purely on-machine-controlled model like the HAVA doesn't require.
How much capacity do I lose by choosing a no-plumbing dishwasher over a built-in model?
Meaningfully less than a standard built-in dishwasher, though the COMFEE in this guide's 6-place-setting rating comes reasonably close to smaller built-in models. If you regularly wash for a large household, a no-plumbing countertop model will still require more frequent cycles than a full built-in dishwasher.
Do I need a specific type of sink to use these dishwashers?
No special sink type is required, just access to a standard kitchen or bathroom sink faucet for filling the tank and a place to empty the wastewater compartment afterward, which is typically also done in a sink or drain.
