Best Garbage Disposal Sink Flange 

When choosing a new garbage disposal for your kitchen, there are various aspects you need to consider, including the drain flange. One reason for this is that drain flanges are not always universal.

On the bright side, some new garbage disposal units come with a sink flange, meaning you don’t have to buy one separately. Even better, some sink flanges are interchangeable between one garbage disposal manufacturer’s model. 

Nonetheless, it’s important to check the specs of any sink flange before buying to ensure it’s compatible with your garbage disposal model. This will ensure that it can hold up to the rest of your kitchen sink and perfectly join the garbage disposal to the sink. 

That said, what is the best garbage disposal sink flange you can buy? More importantly, what is a garbage disposal sink flange in the first? 

Well, let’s start from there! 

What’s a garbage disposal sink flange? 

Also known as a basket strainer, a sink flange is a ring that connects to the kitchen sink and the garbage disposal. More notably, it’s gently sloped to allow water to run into the drain uninterrupted while acting as the mounting bracket for the garbage disposal. Moreover, some garbage disposals come with stoppers/ strainers, which are ideal for capturing food items that should NOT go into a garbage disposal. 

In most cases, a disposal flange/ trim comes with the garbage disposal and is typically crafted from stainless steel. However, if you’re installing the garbage disposal under a sink that is about ¾ to 1 ¾” thick, you may need an extended flange. In that case, an extended collar is designed to fit garbage disposals and fireclay applications. 

To determine whether you need an extended sink flange, make sure you check the product page of the kitchen sink. Also, check if the extended sink flange is compatible with your specific garbage disposal model. 

What size garbage disposal flange do you need? 

To ensure you buy the correct flange side for your food disposal, you have to consider the size of your garbage disposal and the drain. Without these measurements, it will be difficult to determine the right flange size for your garbage disposal. 

Here are 3 simple ways you can use to determine the right flange size for your garbage disposal’; 

• Check the manufacturer’s manual

The easiest way to determine the correct garbage disposal size is to check the manufacturer’s manual. In most cases, you can find this information in the supporting documents that came with your garbage disposal or kitchen sink. 

• Measure 

Alternatively, you can determine the right garbage disposal sink flange by measuring it yourself. This option is relatively straightforward and ideal when you cannot remember the brand or model of your garbage disposal. 

After all, you only need to use a measuring tape and measure inside the edge of the drain across its widest part. Typically, the drain measures between 3 and 4”, which is pretty standard. Next, measure the depth of the drain, while starting at the shallowest point to get a more accurate measurement since most drains slope inward. 

• Online 

Nowadays, you can find almost every piece of information online. So, if you know your garbage disposal or kitchen sink model, just type them online and click on the product listing from the SERPs results. 

If possible, use the product listing from the garbage disposal or sink brand’s website and scroll down to the supporting documents. Click on the manufacturer’s manual to find the specifications you need including the right sink flange size for your garbage disposal. 

Choose a sink flange for your garbage disposal 

Now that you know which sink flange size is compatible with your specific garbage disposal model, it’s time to pick a product that will work with your sink and garbage disposal. In some instances, you may need an extended sink flange, especially if you have a thick sink such as those made of fireclay or natural stone. 

To be precise, if your kitchen sink is about ¾ to 1 ¾” thick, you will likely need an extended sink flange. As the name suggests, an extended flange is longer than typical flanges, making it compatible with thicker sinks. Also, if you’re planning to wash dishes in the sink, make sure you grab a stopper or basket strainer to stop the water.
