Agree that you load from sink, and plumbing is there, other considerations would be if you have an unusual configuration like a corner sink where you might need a cabinet in between so you can comfortably open dishwasher while you stand at sink, or maybe in some cases due to limited space you'd have it across from dishwasher somehow. Also consider unloading, ideally you want easy access to the storage you use for plates, glasses, silverware while the dishwasher is opened.

Ankita, What are your deciding criteria. Stainless Steel, FRP, Quartz, Granite are some of the options. SS is used most commonly. Thanks Nitin.Cornerstone Designs.

SF Firstly, what kind of spaces Are you designing- residential, commercial etc., Which city are you located and focusing to get the client's. Cities like Hyderabad, Bangalore, Chennai have adequate workforce/labor for interior work from carpentry to false ceiling to plumbing and painting. Select a sub contractor whom is well versed with materials first., I.e hardware's required for execution. Drawings are easy but finishing is the main criteria. What materials you want to go, which brands in you want to have? Plywood, laminites, Type of glass, Tiles, Light fitting s etc. Then you can fix the Deal!!

It is fairly easy to do. The best location is next to the sink. You need 16A plug, water connection and a drain outlet. In most cases if it is next to sink, you can use a double angle valve for sink faucet and dishwasher and also can drain into the same drain for sink using a sink drain adapter that has dishwasher connection. The most cost effective way is to buy the standalone type dishwashers that are in the 25-30K price range. In modular kitchen with 85 cm x 60 cm deep and 60 cm wide cabinet space you can achieve a built-in look with those units. I just did that in my new Kochi kitchen.
