How the Five Compare on the Numbers

The five picks split into two groups. The InSinkErator Badger 5 and the Waste Maid Garbage Disposal are the two disposals, and they are the only picks that publish a motor size. The Badger 5 publishes 1/2 hp and a 6.31 inch width. The Waste Maid publishes 1.25 hp, 2800 RPM, and an 8.7 inch width. The Waste Maid is 2.39 inches wider and 4 inches taller than the Badger 5.

The other three picks are a pail, an adapter, and a flange. The iTouchless pail publishes a 13.2 gallon capacity and a 16.1 inch width. The Kraus adapter publishes a 4.5 inch width and a 1.63 inch height. The Ruvati flange publishes a 3.5 inch drain fit and a 3.5 inch width. The Bath Bliss wastebasket, at 0.07 pounds, is the lightest item on the sheet.

The table does not tell you how any of these products perform. No one at Lush has used them. The table also does not tell you noise level, grind chamber size, or installation time, because no pick publishes those figures. It also does not tell you whether the Kraus adapter fits your specific sink, only that the maker states it coordinates with Pax and R0 Pro series sinks.

Disposals: Published Motor and Mounting Figures

InSinkErator Badger 5

The Badger 5 publishes a 1/2 hp Dura-Drive induction motor and a 6.31 inch width. It is the only pick that publishes a 120 V rating. The maker states it fits existing InSinkErator hardware for a quick install. It publishes an 11.5 inch height and a 17 pound weight, the heaviest of the five picks.

The Badger 5 does not publish a capacity, a warranty length, or a decibel rating. The maker states galvanized steel components are used. For a direct replacement where the existing mounting hardware is already InSinkErator, the published fit is the deciding figure. The 6.31 inch width is the smallest published footprint of the two disposals.

Waste Maid 1-1/4 HP Premium

The Waste Maid publishes a 1.25 hp permanent magnet motor and 2800 RPM, the largest published motor on the sheet. It publishes a 12 year warranty on the 658 model and a lifetime warranty against corrosion failure. It also publishes a 3 bolt mounting system for direct replacement of most brands using 3 bolt mounting.

The Waste Maid publishes an 8.7 inch width and a 15.5 inch height, so it needs more cabinet room than the Badger 5. It does not publish a voltage or a capacity. The maker notes that horsepower claimed on the package does not indicate motor output or motor power applied for processing, a statement worth reading before comparing horsepower figures.

Flanges and Adapters: Published Drain Fit

Kraus Pax Garbage Disposal Adapter

The Kraus adapter publishes a 4.5 inch width and a 1.63 inch height. It includes a disposal flange, splash guard, and strainer. The maker states it is compatible with most standard garbage disposal units and coordinates with all Pax and R0 Pro series sinks. It publishes a 1 year limited warranty.

The Kraus adapter does not publish a drain opening size, so a reader cannot confirm a fit from the fact sheet alone. It publishes a 0.5 pound weight. The square shape is published as a contemporary look. For a Pax or R0 Pro sink, the published coordination is the reason to choose this adapter over the Ruvati flange.

Ruvati Garbage Disposal Flange

The Ruvati flange publishes a fit for standard 3.5 inch drain openings and states compatibility with all Insinkerator model disposals. It publishes a gunmetal black nano-PVD finish on stainless steel. The maker notes it is not a pure black color and is intended to match Ruvati gunmetal black stainless steel sinks.

The Ruvati flange publishes a 3.5 inch width and a 4.25 inch height. It includes a removable strainer to trap large food debris. It does not publish a warranty length or a weight. For a sink with a 3.5 inch drain opening and a black stainless finish, the published drain fit and finish are the deciding figures.

Which One Fits Your Kitchen

Direct replacement buyer. The InSinkErator Badger 5 publishes a 6.31 inch width and states it fits existing InSinkErator hardware. If your current mounting is InSinkErator, the published fit is the figure that matters most.

High torque buyer. The Waste Maid publishes a 1.25 hp motor, 2800 RPM, and a 12 year warranty. It needs an 8.7 inch width and a 15.5 inch height, so check the cabinet before ordering.

Pax or R0 Pro sink owner. The Kraus Pax adapter publishes coordination with Pax and R0 Pro series sinks and includes a flange, splash guard, and strainer. It publishes a 1 year limited warranty.

Black stainless sink owner. The Ruvati flange publishes a 3.5 inch drain fit and a gunmetal black finish. The maker states it is not pure black, so match it to a Ruvati gunmetal black sink.

Caregiver buyer. The iTouchless pail publishes a 13.2 gallon capacity, a 40 brief capacity, and an activated carbon filter. It publishes a 16.1 inch width and a 23 inch height, so measure the floor space first.
