Yes, absolutely. A garbage disposer can be installed in a farmhouse sink be it a single bowl or a double bowl. In most cases, for standard thickness farmhouse sinks, you can use the stainless steel drain flange that comes with the garbage disposer. Farm sinks have a standard 3 1/2" drain opening, hence, you may not need to purchase a disposal flange in addition.
EXCEPTION: Thicker farmhouse sinks, particularly some fireclay sinks, will need an extended flange and this can be purchased separately. If an extension is required, it will be provided in the product details of the sink you are interested in.
Note: The standard 3 1/2" basket strainer kitchen drain is for attaching your sink to the plumbing pipes and is not for a garbage disposer. You will need a disposal flange/trim if using a garbage disposer and it is typically included with the disposer you purchase.
- The generally recommended horsepower for a fireclay farmhouse sink is under 1 HP. Most households can get by just fine with 1/2 or 3/4 HP.
- Make sure you have enough room under the sink to house your garbage disposal. Farmhouse sinks are deep and will reduce the amount of space you have in the cabinet below.
- Short on space? Look into compact disposals and talk to your plumber about re-plumbing your drain line and possibly moving the outgoing line down a few inches.
- During installation, do not over-tighten the mounting flange.
- When selecting a disposal flange in a different color and finish ensure it is compatible with the garbage disposal. Check with your plumber or the garbage disposal manufacturer.
