RV dishwasher sizes depend on the style you can install and the space your RV has available. Compact countertop models are about 17 in wide, 17 in deep and 18 in tall, while built-in and drawer models need an opening sized for the exact unit.

Measure the installation spot, the path to it, and room for the door, hoses and service access. A close footprint alone does not prove a dishwasher will fit or work with your water and drain setup.

For the main styles and trade-offs, start with our countertop dishwasher guide. This guide focuses on dimensions and clearances, so you can rule out a poor fit before comparing features.

What RV dishwasher sizes should you compare?

Compare dimensions by installation style, since a countertop unit, drawer and built-in model occupy different kinds of space. The examples below show how compact countertop models vary; they are not a universal size standard.

Measure the actual model before you plan around these figures. Similar names such as compact, portable or RV-ready do not guarantee matching dimensions.

Countertop units also need usable space beyond the cabinet footprint. Account for the open door, hose bends, power cord and the space needed to fill or connect the water supply.

How do you measure an RV dishwasher space?

Measure the usable opening or counter area, then check the route and operating clearances. Use a tape measure and record width, depth and height in inches.

For a built-in or drawer unit, measure the inside opening at the front and back, and near the top and bottom. Cabinets can be uneven, and trim or hinges may reduce the clear space.

For a countertop unit, measure the flat surface where its feet will sit. Check the overhead gap to cabinets and confirm that the front door can open without striking a sink, faucet, cabinet pull or walkway.

Then measure the route from the entrance to the installation spot. Include the RV door, narrow aisles and turns, since the dishwasher may fit in its final position but fail to pass through the route.

Write down these measurements before comparing models:

• Clear width, depth and height of the intended space
• Narrowest doorway and aisle on the route
• Door swing and loading room
• Space for the inlet and drain hoses
• Access to the power source and water connection
• Any required ventilation or service gaps in the manual

Do not plan to force a unit into an opening. Leave the clearances required by its instructions, and make sure hoses are not pinched behind cabinetry.

How much room does a countertop dishwasher need?

A countertop dishwasher needs a stable surface wider and deeper than its footprint, plus room to open the door and route the hoses. Its height also matters if it will sit beneath a cabinet.

The NOVETE and HAVA examples are each about 16.9 in wide, 16.8 in deep and 18.1 in tall. The COMFEE' example is larger at 21.7 in wide, 19.7 in deep and 17.2 in tall.

The smaller footprint does not necessarily mean a better fit. Check the usable space with the unit in place, including the door when open and any faucet or cabinet hardware nearby.

If the counter is too small, consider whether another stable surface can support the unit and keep the hoses within reach. Do not put it where it could slide, block an exit or interfere with normal cooking and sink use.

A tank-fed model may reduce the need for a permanent faucet connection, but it still needs room for filling and draining. Verify the setup details for the model and RV before deciding where it will sit.

What clearances matter around an RV dishwasher?

Clearance means the space needed to operate, ventilate and service the dishwasher, not just a small gap around its sides. Follow the exact manual for required spacing because needs differ by model and installation type.

Check the full door swing and leave room to load dishes without blocking the aisle. In a narrow RV galley, mark the open-door area with tape and see whether it obstructs another appliance or a cabinet.

Plan hose and cord routes before installation. A tight bend, trapped hose or inaccessible plug can make a suitable footprint unusable.

For an under-counter or built-in installation, check the manual for ventilation, mounting and service access requirements. Make sure nearby plumbing, wiring and cabinet supports do not occupy the space the unit needs.

Will the dishes fit inside the dishwasher?

Check the largest dish you use, not only the outside dimensions. Interior racks, loading angles and spray clearance can limit what fits even when the exterior is small.

NOVETE says its model accommodates dishes up to 12 in loaded at an angle. HAVA says its model accommodates dishes up to 11 in at an angle, while COMFEE' lists plates up to 10 in in diameter.

Measure your dinner plates, bowls and any cookware you expect to wash. Compare those sizes with the model's stated capacity and loading directions.

Place settings are also not a direct measure of every load. A rack that fits several place settings may have less room for a wide pan, travel mug or unusually shaped dish.

Which countertop dishwasher dimensions should you compare?

Compare width, depth, height, dish clearance and water setup together. These three models illustrate why looking at only one measurement can lead to a poor choice.

NOVETE: compact footprint with angled plate loading

The NOVETE measures about 16.9 x 16.8 x 18.1 in and fits dishes up to 12 in when loaded at an angle. Its stated capacity is 4 place settings.

It has a built-in 5 L water tank and supports faucet connection through its inlet hose. Decide where the drain hose will empty and whether you can reach the tank for filling.

Choose it if the measured counter fits its footprint and your dishes fit its rack. Check the open-door area and overhead gap before setting it beneath cabinets.

HAVA: similar footprint and an included tank

The HAVA measures about 16.9 x 16.8 x 18.1 in and is described as holding 4 place settings. Its stated maximum dish size is 11 in when loaded at an angle.

It can use the built-in tank or connect to a faucet with the included hose. The chosen water method affects where the unit can sit and how you route the drain.

Choose it if your available space matches the footprint and your largest dishes are within its stated limit. Measure the route and leave room to fill or connect the unit.

For a narrower cabinet arrangement, compare the RV dishwasher drawer options and their installation needs.

COMFEE': larger footprint and six place settings

The COMFEE' measures 21.7 in wide, 19.7 in deep and 17.2 in tall. It is described as a 6-place-setting model that fits plates up to 10 in in diameter.

It connects to a faucet with a suitable adapter. Include the faucet, adapter and hose path in your measurements, especially if the RV sink area is tight.

Choose it only when you have the extra counter depth and width. Compare the actual dish sizes you use with its 10 in plate limit.

Should you choose a drawer, built-in or portable RV dishwasher?

Choose the style that fits your available space and installation plan. A portable countertop model uses a counter, while drawer and built-in units depend on a matching cabinet opening and more involved installation.

A drawer dishwasher can suit a layout where a traditional full-height door is awkward, but its dimensions and cabinet requirements still need checking. Read our guide to a drawer dishwasher for an RV before planning the opening.

A built-in unit needs a cabinet space that matches its installation dimensions, plus service access and compatible plumbing. Our built-in RV dishwasher guide covers the measurements to compare.

Portable models give you more placement options, but the word portable does not mean every model is easy to move or suitable for every RV. Compare the best portable dishwasher for an RV after measuring your counter and route.

What should you check for water and drainage?

Check how the dishwasher takes in water and where it sends wastewater before choosing a location. A correct physical fit does not guarantee that your RV plumbing can support the setup.

Some countertop models include a water tank and can also connect to a faucet. Others require a faucet connection and a suitable adapter.

Confirm the selected model's water method and the adapter fit before purchase.

Use our Faucet Adapter Size Chart for Countertop Dishwasher to check common connection sizes. Confirm the actual faucet thread and hose requirements for your sink.

Plan a drain route that stays secure and reaches an approved drain point. Keep the hose from kinking, stretching across a walkway or interfering with cabinets and drawers.

What is the final RV dishwasher size check?

Choose an RV dishwasher only after the unit, route and operating clearances all fit. Compare your written measurements with the exact model and its installation instructions.

Pick a compact countertop unit if its footprint, dish limit and hose setup match your RV. Consider a drawer or built-in model only when the cabinet opening and service access match its requirements.

For RV dishwasher sizes, measure first, then choose by style: NOVETE or HAVA for a roughly 17 x 17 in counter area, COMFEE' when you have a larger footprint, or a cabinet-installed option when its opening is confirmed.

Frequently asked questions

What size dishwasher fits in an RV?

The right size depends on the installation style and the space available. Compact countertop examples are about 17 in wide, 17 in deep and 18 in tall, while a built-in or drawer dishwasher needs an opening that matches its own dimensions.

Measure the space, route and service clearances before buying.

Can a countertop dishwasher fit in an RV?

A countertop dishwasher can fit if the counter has enough room and can support it, and if the door can open without blocking nearby space. Check the unit's footprint, height, hose route, power access and drain destination.

Also confirm that its water supply method works with your RV setup.

How much clearance should I leave around an RV dishwasher?

Use the clearances in the specific dishwasher's manual because there is no single gap that fits every model. Leave room for ventilation, the door, hoses, plugs and routine access.

Measure nearby cabinets and appliances with their doors open so the dishwasher does not block normal use.

Are RV dishwasher dimensions the same as standard countertop models?

No. Countertop models can differ in width, depth, height and interior capacity, while built-in and drawer units use different installation spaces.

Compare the exact outside dimensions and required opening for each model.

A similar capacity or label does not guarantee the unit will fit your RV.

Should I measure the inside or outside of an RV cabinet?

Measure the clear inside opening for a built-in or drawer dishwasher, including width, depth and height at several points. Also check the outside route to the space, door swing, trim and service access.

For a countertop model, measure the usable counter and overhead clearance instead.
