Honeywell 18 Inch Dishwasher with 8 Place settings, 6 Washing Programs, Stainless Steel Tub, UL/Energy Star- White vs Sharp SDW6504MS Stainless Steel Dishwasher, 24-inch Pocket Handle, 52 dB, Hybrid Tub, 12 Place Settings, 5 Cycles, Heated Dry

Size and Capacity: Sharp Offers More Space

The Sharp SDW6504MS provides a significantly larger capacity than the Honeywell 18 Inch Dishwasher. With a 12-place setting capacity, it can handle more dishes per cycle, making it better suited for larger households or frequent entertaining. In contrast, the Honeywell model is rated for only 8 place settings, which may limit its usefulness for bigger families. The Sharp’s fold-down tines and adjustable upper rack further enhance loading flexibility, accommodating taller items and varied dish shapes. This design allows for smarter use of space within the 12-setting limit. While both units are built-in, the Sharp’s 24-inch width offers more room compared to the Honeywell’s 18-inch footprint, though exact dimensions aren’t provided in the data.

Washing Programs and Efficiency: More Options on the Sharp Side

The Sharp SDW6504MS features five washing cycles, including a half-load option that reduces water and energy usage—ideal for smaller loads. It also includes a sanitization cycle to reduce bacteria, beneficial for families prioritizing hygiene. The Honeywell model offers six programs: pots & pans, normal wash, china, quick wash, rinse only, and energy saver. While this gives slightly more program variety, the absence of a half-load feature means it uses more resources even for small loads. Both models support delayed start (up to 24 hours), but only the Sharp explicitly mentions a sanitization cycle. The Honeywell’s Energy Star certification confirms low energy consumption, but no specific efficiency metrics are given beyond that label.

Noise Level and Quiet Operation: Sharp Wins on Sound

The Sharp SDW6504MS operates at just 52 dB, described as library-quiet, making it ideal for open-concept kitchens where noise is a concern. This level of quiet operation is specifically highlighted in its product description. The Honeywell model does not mention any noise rating, so there's no basis to compare sound levels directly. Without such data, it cannot be confirmed whether the Honeywell is quieter or louder. However, the Sharp’s emphasis on “whisper-quiet” performance and its 52 dB specification provide clear evidence of superior acoustic design. For users sensitive to appliance noise, especially during evening or nighttime use, the Sharp’s lower decibel level is a decisive advantage.

Interior Construction and Durability: Hybrid Design vs. Full Stainless Steel

The Sharp SDW6504MS uses a hybrid tub construction combining a stainless steel interior with a heavy-duty plastic floor. This design aims to balance durability and cost-effectiveness while maintaining performance. The Honeywell 18 Inch Dishwasher features a full stainless steel tub, which is generally associated with greater longevity and resistance to corrosion. However, the Sharp’s hybrid approach still claims optimal performance, suggesting it maintains strong functionality despite using plastic in part of the tub. Neither model specifies the thickness or grade of the stainless steel, so direct material quality comparisons are not possible. Still, the full stainless steel tub in the Honeywell may appeal to buyers seeking maximum durability, while the Sharp’s hybrid system offers a different engineering compromise.

Loading Flexibility and Rack Design: Adjustable Racks Give Sharp an Edge

The Sharp SDW6504MS includes an upper rack with a 2-inch height adjustment capability, allowing users to accommodate taller dishes like wine glasses or large platters without compromising load size. This feature enhances versatility and makes loading easier. Additionally, the fold-down tines offer flexible placement for various dish types. The Honeywell model has a top cutlery rack and two other racks with a removable basket, but no mention is made of adjustable height or foldable components. While both models claim good loading capacity, the Sharp’s ability to reconfigure the upper rack provides a tangible advantage in real-world use, particularly for households with diverse dishware.

Price and Value: Nearly Identical Pricing with Slight Edge to Sharp

Both dishwashers are priced very closely: the Honeywell 18 Inch Dishwasher is $399.99, while the Sharp SDW6504MS is $399.00—about $1.00 cheaper. This represents a savings of roughly 0.25% on the Sharp model. Despite the minimal price difference, the Sharp offers more capacity (12 vs. 8 place settings), a quieter operation (52 dB), a half-load option, and adjustable racks. The Honeywell’s Energy Star certification and full stainless steel tub are notable, but they don’t offset the functional advantages of the Sharp. Over time, the Sharp’s efficiency features could lead to lower utility bills, adding value beyond the initial purchase price.

Which should you buy?

Choose the Sharp SDW6504MS if you prioritize capacity, quiet operation, and flexible loading. It handles 12 place settings, runs at just 52 dB, and includes a half-load option and adjustable upper rack—features absent in the Honeywell model. Though both are priced nearly identically ($399.00 vs. $399.99), the Sharp delivers more value through enhanced functionality and efficiency. The Honeywell 18 Inch Dishwasher is a compact, Energy Star-certified unit with a full stainless steel tub and six washing programs, but it lacks the advanced features and higher capacity of the Sharp. Given the bestseller rank of 132 for the Sharp versus 318 for the Honeywell, consumer preference leans toward the former. For most buyers seeking a modern, efficient, and versatile dishwasher, the Sharp SDW6504MS is the superior choice.
