However, if your old trash disposal is no longer adequate, or if you wish to get one installed, it's time to consider how much it costs to install a garbage disposal or buy a new one. Let's find out.

How Much Does It Cost To Install A Garbage Disposal?

Garbage disposal makes cleaning the kitchen a breeze by breaking down large chunks of food waste into smaller bits that you can flush away more easily. If the trash disposal suddenly stops working, it is critical to have it repaired as soon as possible to avoid future problems.

The price of garbage disposal installation ranges from $150 to $950. The average garbage disposal installation cost is $400.

The Work's Scope Determines The Cost Of Installing A garbage Disposal

Some individuals misunderstand how garbage disposals work. For example, a set of blades does not protect the Drain's entrance. The food is subsequently transferred to a revolving disc lined with sharp shredders. The waste is further shredded so that it can be flushed down the Drain and disposed of in the sewage.

If your trash disposal springs a leak, the motor burns out, or it won't switch back on after you push the reset button, it's time to replace it.

However, the overall cost of repairing or installing waste disposal greatly depends on the usage scale.

Cost Of A New Garbage Disposal

The average cost of replacing trash disposal is $400. The cost is roughly the same as installing brand-new disposal minus the cost of any additional wiring that is presumed to be there already.

According to the owner of a well-known plumbing firm and a member of the Expert Board, replacing existing disposal is a simple procedure. The addition of electrical components raises both the project's complexity and cost.

Several Factors That Determine The Cost Of Installing Trash Disposal

How much do trash disposals usually cost? A variety of factors determine the cost of installing trash disposal. For example, one of the important aspects influencing the final installation cost is the size of the unit, in conjunction with the type of material utilized to make the unit.

Plumbing modifications and new electrical outlets may raise or lessen the project's overall cost. To estimate the cost of replacing trash disposal, homeowners should consider the following factors.

  • Cost Of garbage Disposal
  • Size Of Garbage Disposal
  • Type Of garbage Disposal
  • Plumbing Parts

Continuous Feed Garbage Disposal

Homeowners can choose between two forms of garbage disposal. The standard is the continuous-feed variety. A toggle switch operates it on a wall and, as the name suggests, runs continuously when switched on—continuous-feed trash disposal costs around $1,100 on average.

Material Of Garbage Disposal

The price of a trash compactor is mostly dictated by the material used to build it. The principal material used in garbage disposals is often aluminum or stainless steel. Both are available in various forms and sizes and in continuous or batch feed configurations.

Electrical Outlet Wiring Costs

If you don't already have a grounded electrical outlet, you may have to pay to install one to utilize a garbage disposal. It is not out of the question to spend between $5 and $10 on supplies, plus $120 to $165 to hire an electrician to install a grounded outlet. If your installation requires a new switch, you should budget an additional $50 for labor and another $5 to $10 for supplies.

The National Electrical Code does not require garbage disposal ground-fault circuit-interrupter (GFCI) protection. Although it may appear strange, GFCI outlets may be needed by your city's construction department.

The Motor Of Garbage Disposal

The size of its motor largely influences the cost of garbage disposal. The smallest garbage disposals are designed for single-family homes, while the largest is designed for commercial kitchens. If a homeowner wants to save money and keep their unit in good working order without breaking the bank, they should purchase a unit appropriate for the number of people living in their home.

Trash disposal suitable for a one- or two-person home would have a 1/3- or 1/2-horsepower engine, which would cost between $75 and $200, but a 5- to 8-person household would benefit from a 1-horsepower motor, which would cost between $200 and $500.

The Motor Of Garbage Disposal

Garbage Disposal Installation According To Budget

New trash disposal can cost anywhere from $85 to $200, depending on feed type, brand, materials, and motor size. Normal trash disposal will cost between $53 and $89 for a 1/3 HP machine, $51 to $119 for a 1/2 HP unit, $96 to $219 for a 3/4 HP unit, and $132 to $332 for a 1 HP machine.

$50 to $350

Prices in this category are frequently what homeowners pay when they install their disposal. If you choose a small motor and brand that falls within that price range, the average cost will be closer to the low end of this range.

$350 to $600

Whether you live in the heart of Manhattan or Nebraska, you should expect to pay in this range for a simple trash disposal installation. The cost includes disposal and installation, which may entail additional wiring. If you have a septic system in your home, you'll need a slightly different type of trash disposal.

$600 And Up

Higher horsepower motors, intricate wiring, and a new sink installation might drive the price well past $600. This is the average price range for remodeling projects that include an addition.


We can deduce that the average lifespan of garbage disposal is ten years. Because the cost of proper garbage disposal is roughly the same as the repair cost, replacing it is usually more cost-effective. If the required wiring is still present, you should be able to replace the trash disposal.

Find a replacement disposal that is the same size and shape as the old one. If you decide to go with a completely new design, you may need to modify the drain piping, which will add to the difficulties of the replacement.
