Compare your requirements with HAVA R01 and Danby DDW631SDB

Enter your kitchen measurements

Choose inches or centimeters. We’ll check the closed body, water requirement, and plate limit where documented. You’ll see known mismatches and the details still needing confirmation.

Planning an enclosed cupboard? Check cabinet-placement approval and working access before treating a body-size match as a usable installation.

Enter the clear space available in your selected unit. All three space measurements are required; plate diameter is optional. Press Enter or use the button to check. If you change an answer, run the check again.

Download the 2-page measurement checklist (fillable PDF, 23 KB). Print it or save your measurements in a PDF reader while comparing exact models.

Your measurements stay in this browser. No account needed. This comparison currently covers two models.

Illustrated Small Kitchen Notes guide

Have these ready

  • A tape measure with inch or centimeter markings
  • The intended spot beside your sink
  • Your largest everyday round plate
Example: With an 18-inch height limit and a must-have tank, neither of these two models qualifies. The checker explains why.

Compare your own model’s measurements

Use the kitchen dimensions and measurement units entered in the checker above. Then copy the body dimensions from the current manual for your exact model. This worksheet calculates space remaining; it does not add the model to our researched recommendations.

Enter all dimensions in inches. Changing the unit selector above converts completed dimensions in both tools.

Add operating clearances from the manual, if known

Use the total extra space required beyond the body in each direction. For example, add the left and right side clearances for width. If a drawing gives a total dimension including clearance, subtract the body dimension first. Leave an unknown value blank; enter zero only if the manual supports it. This rectangular check cannot assess the door’s swing path, hose bends or access for top filling.

Enter available kitchen measurements above and your model’s body dimensions here.

Nothing is submitted to Small Kitchen Notes. A positive gap is not installation approval. Confirm support, permitted location, electrical supply, water/drain arrangements, door movement and filling access in the exact instructions. Check cabinet and enclosure restrictions.

Two models. Two different needs.

Start with the water setup, then check the size.

For keeping your faucet free

HAVA R01

Fill its built-in tank instead of connecting a supply hose to your tap.

5 L tank18.1″ tall16.9″ wide

Check first: it is too tall for an 18-inch opening. You still need drainage and room to fill the tank.

For a lower cabinet opening

Danby DDW631SDB

A shorter body with a wider footprint, supplied through a faucet connection.

Faucet supply17.25″ tall21.65″ wide

Check first: faucet compatibility and operating clearance. There is no refillable tank.

Manufacturer footage; research-based recommendations. We have not physically tested these models. Check the current seller, price and return terms on Amazon.

Before you place an order

Measure the space the machine can actually use.

  1. Height: counter surface to the lowest overhead obstruction. Include trim and under-cabinet lights.
  2. Width: the narrowest clear side-to-side space. Keep room for anything you still need to reach.
  3. Depth: the usable supporting counter. Door-open space and hose routing are separate checks.
  4. Plate: the widest diameter of your largest round dinner plate. An angled fit can change the loading arrangement.
A close fit needs more checking. A 17.25-inch body in an 18-inch gap leaves 0.75 inches by subtraction. That is not a verified ventilation allowance.
The questions behind the measurements

What does “fits” really mean?

Can I use a tank model without plumbing it in?

A built-in tank can remove the need for a faucet supply connection. You still need a permitted drain arrangement, filling access, and the exact model’s installation requirements.

Does passing this checker mean I can order?

Not yet. It means the documented fields checked show no known mismatch. Confirm door access, filling, hoses, clearance, the exact product version, and the seller’s return terms.

What if neither model qualifies?

Read the listed reason for each exclusion. This checker covers only two models, so a no-match result is not a claim that nothing on the market will work.

Which one washes or dries better?

We haven’t physically tested either model. Our comparison covers documented fit and setup constraints; we cannot name a performance winner.

Illustrated kitchen conversation.
A useful question to start with
“Will it make my everyday cleanup easier?”

Start with the dishes you wash most, the counter space you can spare, and how you will supply and drain the water. A good shortlist works for all three.

Why the R01 screen uses the larger published body

HAVA’s product page lists a 16.9 × 16.9 × 18.1-inch body. Its linked manual instead lists 16.86 × 16.75 × 18.05 inches. This checker retains the larger product-page figures as an initial screen. Neither height fits a fixed 18-inch opening, and passing the screen does not approve installation clearances or filling access. Read the R01 source comparison before a close-fitting purchase.
