Once you own a kitchen waste disposal unit, you’ll wonder how you ever went without. This little gadget is designed to slot under your sink and eats up all that kitchen waste that can’t be recycled. It does this by grinding the waste down into fine particles before disposing of it down the drains. This ensures you make fewer trips to empty the kitchen bin and also means it’s environmentally friendly as less waste will ultimately end up in landfills.

It’s a fast, convenient way of vastly reducing the amount of waste your kitchen produces on an annual basis.


Made in the USA
1 Stage Grind

1 Stage Grind Process

This Insinkerator waste disposal unit features one stage of grinding. This process is where food is ground once before passing through drain pipes with water.

Air Switch

Built-in Air Switch

As the name suggests the air switch uses air pressure rather than electricity to activate the unit. This, in turn, reduces the risk of potentially getting an electric shock if your hands are wet.

sink stopper

Stainless Steel Sink Stopper

Waste disposal units are incredibly family-friendly as no sharp knives or blades are used. The Model 66 waste disposal unit is a brilliant addition to any kitchen. When the unit is not in use, you may find it handy to place the chrome sink stopper over the chute opening, to help protect the unit from any unwanted waste.

Removable Baffle

Removable Easy to Clean Baffle

Quieter than your bog-standard waste disposal unit, the removable sound baffle is used to help reduce the amount of noise that your unit makes whilst in operation – ensuring minimal disruption in your kitchen. The baffle is also removable, making an easy job of cleaning.  This is the perfect model for those who love to entertain, no one wants a noisy disposal unit whilst you’re trying to tell your funniest stories!

    I ordered this insinkerator to replace an old model we'd installed 20 years ago. I would highly recommend these. It's so easy to get rid of your food scraps without having them rotting in the bin. Easy to install, quite to run and extremely efficient. Wouldn't be without one. And Plumbworld's price way outdid any other company. Will definitely recommend and deal with this company again.

    Have just had this installed and am very impressed by how quiet it is. Although it is early days so far I hope it will continue to work as it does at the moment as it appears to be very efficient. I have not registered the purchase as there seems to be no paperwork to cover the guarantee.

    Great product and Did It Myself following very clear instructions. Worst bit was buying the correct plumbing parts to perfect the connection…and drilling the granite for the air switch. Plumbworld price guarantee worked just as well too.
