Level it up and test it for evacuation before it's installed please. Your plumber isn't going to have any problems.

I have a rear drain sink and hubby didn't have any problem putting in the garbage disposal.

Sink dimensions

• Sink is 22" deep
• Sink overhangs front edge of cabinet 1-1/2".
• Distance to rear of sink rim: 18-1/16" + 1-1/2 = 19-9/16"
• Distance to rear of sink bowl: 19-9/16" - ( 19-9/16" - 16-7/8" ) / 2 = 18-7/32"
• Distance to center of drain: 18-7/32" - 4-3/4" = 13-15/32"
• Cabinet depth: 24"
• Distance from wall to center of drain: 24" - 13-15/32" = 10-17/32" <-- plenty of space

That is an odd configuration.

I don't think it being in the rear will impact your garbage disposal.

I have a farmhouse sink but my drain is the the rear and at one side. I opted for this deliberately for two reasons

1. The garbage disposal and trap don't sit in the middle of the sink cabinet wasting "real estate". Having it rear offset enabled me to fit a disposal unit AND a pull out trash container in the sink cabinet. I also have the bottom roll out so that I can use all of the storage under the sink

2) By having the drain on one side I can stack dishes on one end of the sink without blocking the drain. For most sinks that have a drain in the middle you would be blocking the drain if you stack dishes in there unless the sink is enormous.

However I don't understand why the drain would be in the MIDDLE and in the rear because there doesn't seem to be a functional reason for that configuration.

That’s true. I was just reading the reason most farmhouse sinks have rear drains is to give extra space underneath. I didn’t realize this & never even noticed when I ordered . I just wanted to be sure the garbage disposal will work with it. Thanks all!

Number of farmhouse sinks by drain location at build.com: Center: 136, Rear: 65, Right: 21, Left: 5, Corner: 1.

@wdccruise That the configuration exists doesn't explain why this configuration exists. As my original post stated I understand why a rear offset drain (e.g. to the side) makes sense but if you have the drain in the middle you are still having a large garbage disposal cutting the sink cabinet below in half and thus not enough room for a roll out trash bin.

@Helen: "That the configuration exists doesn't explain why this configuration exists"

Of course it does. Manufacturers produce what consumers buy. If consumers wanted sinks with drains "to the side", manufacturers would produce more of them. But consumers don't, hence the ratio of 136:26 aka 5:1.

@wdccruise it merely shows that many consumers aren’t aware of options and what can achieve greater functionality.

I wasn’t aware of many things when I started my remodel including rear offset drains and the advantages of same. This is a site in which people come who want to make as educated decisions as possible and not necessarily purchase the most prevalent when there are better options.

Manufacturers sell many products which aren’t necessarily the best option.

@Helen: "not necessarily purchase the most prevalent when there are better options.

"Manufacturers sell many products which aren’t necessarily the best option."

Millions of consumers have spoken via their purchase decisions and they don't agree with you. Fortunately we have a free market.

@wdccruise I still don't understand why the prevalence of a certain model has any significance in terms of evaluating whether it is the best or most functional choice.

When I was researching appliances for my remodel I became aware of side opening ovens and French door style wall ovens. This are much more ergonomically functional in terms of enabling the cook to more comfortably use the oven - which is the theoretical purpose of a wall oven.

No one I knew was aware of these options until I told them what I was getting. Many more ovens are hinged from the bottom which doesn't mean they are the best option someone could collect. Once I explained how it enabled me to load and unload from the front everyone thought the configuration was indeed more functional.

I didn't realize that an offset rear drain existed until I read about in on one of these forums. It was unlikely that I would have stumbled upon it if I just browsed through sinks. However once I learned about them and learned why some people had opted for them because of functional reasons I limited my sink options to those which had a rear offset drain because that configuration was more functional.

You keep saying that a configuration is *best* or *most functional* because there are more of them on the market. I just find that a strange justification on a site which is frequented by people who are trying to educate themselves on all of the possibilities and analysis on how they might function better (or worse) for them instead of choosing the most "popular".

@Helen: "I still don't understand why the prevalence of a certain model has any significance in terms of evaluating whether it is the best or most functional choice."

Because millions of consumers have evaluated the options and purchased the product they deem "best" and "most functional" and manufacturers have responded by offering more of the product that consumers have determined to be "best" and "most functional" and consumers don't agree with you.

And consumers have also decided that they prefer a shallower oven door (because it's the height of the oven) and swings down than deeper oven door (because its the width of the oven) that swings to the side, that they don't need to put their faces within inches of the 350+ degree oven opening, and that they don't want next to their arm a large hunk of hot metal and glass with which they could easily come in contact and that could swing closed at any time.
