The most common size pipe for modern drains is 1 1/2 inches in diameter, but there are also 2-inch and 3-inch pipes available. Some older sinks may have even smaller pipes like 1 1/4-inch in diameter but these are not as common.
In the kitchen and bath the standard size in Australia for the plug is 1 3/4 inch. For bathroom vanities the standard size is 1 1/2 inch.
Utility sinks may range in size from 8” deep to more than 24” deep.
There are three common drain sizes for bathroom sinks, 1.25", 1.5" and 1 5/8 (1.625"). You need to select a drain that is the same size or SMALLER than the hole in your sink. For example, if you have a sink with a drain hole of 1.75", than any of the drains 1.25", 1.5", or 1.65" will work.
The correct rough-in height for sink drains to pass the inspection is between 18 and 20 inches. Standard sink drains usually start from 24 inches and stop at 28 inches, so the rough-in height should be slightly lower than this height range.
The most common kitchen counter height is 36 inches, but it can vary from 30 to 45 inches. The standard kitchen sink is 8 inches deep, which means that the normal distance between a kitchen sink drain and the floor is 28 inches.
Supply line (vertical): two holes, each 2-3 inches above the drain line. Supply line (horizontal): 4 inches to left and right of the centerline, respectively. Discharge/drain hole (vertical): 16-20 inches from floor. Fixture (side to side buffer): 15 inches minimum from centerline, 20 inches recommended.
The most common size pipe for modern drains is 1 1/2 inches in diameter, but there are also 2-inch and 3-inch pipes available. Some older sinks may have even smaller pipes like 1 1/4-inch in diameter but these are not as common. If you have a standard kitchen sink drain, then a 1 1/2-inch pipe is typically sufficient.
To check the kitchen sink drain size, take a measuring tape and place it across the center of the drain hole. That way, you'll get the maximum width between two opposite points. This should be the exact size of the drain opening for your sink.
What Is a Laundry Sink? Often called a utility sink, a laundry sink is a rugged, large-capacity sink used primarily for cleaning or soaking clothing. A laundry sink is also used for washing items unrelated to clothing, such as paintbrushes.
Unlike the traditional kitchen or bathroom sink, laundry tubs are designed to have extra depth and a wider surface area so that they can accommodate a wide range of things, including large loads of clothing and oversized items that won't fit in the washing machine.
A utility sink is usually a deeper, larger, and more versatile sink than the kitchen or bathroom sink. It is most often used in a utility room (hence its name) or another out-of-the-way space.
PVC Pipe Sizes in Australia
The external diameter of the pipe is 34mm. 20mm or ¾ inch pressure PVC pipe (in this case, class 12), has an internal diameter of 23mm with an external diameter of 27mm.

Traps come in 1-1/4 inch (standard bathroom sink) or 1-1/2 inch (standard kitchen sink) inside diameter sizes. Be sure to check so you get the right size replacement at your local store. In this guide we'll show you how to replace a P-trap in a few easy steps.
Your choice of sink strainer relies heavily on the drain opening and depth of your sink. The most commonly used strainers typically range between 3-½ inches to 4-½-inches in diameter.

Are sink drains universal? Kitchen sink drains have a universal diameter. It doesn't matter if you're using a double-basin sink, or a single-basin sink, the drain hole diameter is 3 and ½ inches. This is larger than a bathroom drain, and the same size as a standard bathroom drain.

As long as your sink is above the drain it will work. Looking at your photo I would shorten the drain line from the wall. Make you get everything sealed or it will leak but it will work because the drain is below the sink bottom.
What is the minimum and maximum distance a P-trap can be below a sink? There is no minimum distance specified by the building code, but the maximum is 24” per International Residential Code (IRC) and Residential Edition of Florida Building Code (FBC 1002.1), measured from fixture outlet to trap weir.
There are pros and cons to centered and offset drains. But to sum up, we recommend offset drains for small and busy kitchens, and centered drains for larger sinks and quick renovation projects.
