ZLINE vs Thor Kitchen Dishwashers: Specs Compared

What you are comparing when you look at ZLINE and Thor Kitchen

ZLINE Kitchen and Bath and Thor Kitchen both sell built-in dishwashers designed to match their ranges and range hoods. Both brands offer stainless steel exteriors and a pro-style look, but the specs inside each model are what decide how well it fits your kitchen. The four areas that matter most are capacity, noise rating, cycle options, and construction.

Capacity is stated in place settings, which tells you how many place settings and serving pieces the tub can hold. The ENERGY STAR program defines a standard-capacity dishwasher as one that holds eight or more place settings plus six serving pieces, and a compact model as one that holds less than that. Both brands sell standard 24-inch models and some 18-inch compact models, so check the place setting count on the specific model you are considering.

Noise is stated in decibels (dB). A lower dB number means a quieter dishwasher. There is no industry standard that requires a brand to publish this figure, so not every model lists it. When a model does list a dB rating, compare it directly with the other brand's model at the same width.

Cycle options control how the dishwasher washes. A model with more cycles may handle a wider range of loads, from delicate glassware to heavily soiled pots. Some cycles, like a sanitize cycle or an energy-saving cycle, change the water temperature and duration.

Construction includes the tub material, the spray arms, the racks, and the door seal. A stainless steel tub holds heat better than plastic, which helps with drying and sanitizing. Stainless steel interiors also resist odors and staining better than plastic over a long service life.

Keep in mind that both brands offer multiple model lines. One ZLINE model may have a stainless steel tub while another has plastic interior parts. The same applies to Thor Kitchen. The brand alone does not tell you the specs; the individual model's spec sheet does.

Capacity: place settings and tub size

Capacity is the first spec to compare because it decides how many dishes you can wash in one load. The ENERGY STAR product page explains that standard-capacity models hold more than eight place settings and six serving pieces, while compact-capacity models hold less than eight place settings and six serving pieces.

ZLINE and Thor Kitchen each offer 24-inch built-in models and 18-inch compact models. A 24-inch model with a tall tub can typically hold more place settings than an 18-inch model, but the exact count varies by model. Look for the place setting number on the spec sheet, not the width of the cabinet opening.

A household that cooks at home regularly and entertains will want a 24-inch model with a high place setting count. A small household or a kitchen with a narrow opening may prefer an 18-inch model. If cabinet space is your constraint, measure the opening before choosing a width.

Dishwasher capacity is not just about how many plates fit. The rack configuration matters too. Some models have a third rack for utensils, which adds loading flexibility without increasing the tub size. If you load large pots or tall glasses, check the rack height adjustments on each model.

Noise: what the dB rating means

Noise is measured in decibels (dB). In a dishwasher context, the dB rating describes the sound pressure level during the wash cycle. A lower number is quieter. A difference of a few dB is noticeable, because the decibel scale is logarithmic.

ZLINE and Thor Kitchen models list different dB ratings depending on the model. Some models are rated in the mid-40s, which is quiet enough for an open kitchen or a kitchen near a living area. Others are rated in the 50s, which is louder and may be fine if your dishwasher is in a utility room.

There is no standard that requires every brand to publish a dB rating, and there is no single testing method that all brands use. The dishwasher decibel levels comparison page explains the testing standards in more detail. When a model does not list a dB rating, you cannot reliably guess its loudness from the brand alone.

If quiet operation is a priority, check the dB number on the spec sheet and compare it across the specific models you are considering. A model rated at 44 dB will sound noticeably quieter than one rated at 50 dB. For more background on what these numbers mean, read our explanation of dishwasher dB ratings.

Remember that noise is not only about the motor. The spray arms, the drain pump, and the water fill valve all contribute. A dishwasher's construction, including insulation and the tub material, affects how much sound reaches the room.

Cycles and options: what each model offers

The number of wash cycles on a ZLINE or Thor Kitchen model varies by model line. Entry-level models usually have fewer cycles, while higher-end models add options like a heavy-duty cycle, a delicate cycle, a quick wash, and a sanitize cycle.

An auto-sensing cycle, which the ENERGY STAR page describes, uses a soil sensor to detect how dirty the water is and adjusts the cycle accordingly. This saves water and helps ensure dishes come out clean. Not every model has a soil sensor, so check the spec sheet if this matters to you.

A sanitize cycle raises the water temperature to reduce bacteria. If you want this option, look for it on the model's spec sheet. A high-temperature wash cycle is different from a sanitize cycle; the sanitize cycle uses a higher temperature and holds it for longer. Our sanitize cycle page explains the difference.

Drying options also matter. Some models include a heated dry option, which uses a heating element to speed drying. Others use a condensation drying system or a fan-assisted system. The cycle list on the spec sheet will show which drying options are available.

The number of cycles is not the only factor. Cycle time matters too. A heavy-duty cycle on one brand may run significantly longer than a comparable cycle on another. Check the estimated cycle time on the spec sheet if you care about how long a full wash takes.

For a full breakdown of the common cycle types, see our guide to dishwasher cycles.

• Heavy-duty or pot-scrubber cycle
• Delicate or glassware cycle
• Quick or express cycle
• Sanitize cycle
• Auto-sensing cycle with soil sensor
• Energy-saving or eco cycle
• Heated dry or condensation dry

Construction: tub material and build quality

Construction is where ZLINE and Thor Kitchen models can differ most from each other. The tub material is the biggest factor. A stainless steel tub holds heat better than plastic, which improves drying performance and helps the sanitize cycle reach its target temperature. Stainless steel also resists odor absorption and is less likely to crack or discolor over time.

Some models in both brands use a stainless steel tub, while others use a plastic or composite tub. The spec sheet will state the tub material. If you regularly run hot cycles or want the best drying results, prioritize a stainless steel tub. Our guide to stainless steel versus plastic tubs covers the trade-offs in depth.

Spray arm material also matters. Stainless steel spray arms resist mineral buildup and are more durable than plastic spray arms. Not all spec sheets list the spray arm material, so if you cannot find it, contact the brand's support or check the manual.

The door seal and the rack coating affect long-term reliability. A well-sealed door prevents leaks and keeps noise inside. The rack coating protects the wire from rust. If you live in an area with hard water, both the spray arms and the rack coating will see more wear.

Check the model's dimensions, including height, width, and depth. A 24-inch model is the standard width, but the height and depth can vary slightly between brands. Make sure the model fits your cabinet opening and that the door can open without hitting the surrounding cabinets.

How to compare the two brands on paper

When you have narrowed down to one ZLINE model and one Thor Kitchen model, put their spec sheets side by side and compare these fields: place settings, dB rating, cycle list, tub material, spray arm material, and dimensions.

Start with capacity. If one model holds two more place settings than the other, that is a real difference in what you can wash per load. Move to noise. A 3 dB difference is audible and meaningful for an open-plan kitchen. Then compare cycles: does the quieter model still have the sanitize cycle or the quick cycle you want? Last, look at construction: a stainless steel tub is generally a better long-term investment than plastic.

Do not rely on the brand's name alone. ZLINE does not build every model with the same specs, and neither does Thor Kitchen. The same is true for any dishwasher brand. The model number and its spec sheet are the only reliable basis for comparison.

If you are choosing between 18-inch and 24-inch models, our comparison of 18-inch versus 24-inch dishwashers will help you decide which width fits your needs.
