What is going on with the cabinet, or is there a cabinet? Does it have doors that create a center line? Does it have an opening for a basin or is it a vessel sink basin (a bowl that sits on top of the cabinet). A picture would help us help you in the best possible way, but not having seen it- 99.9% of basins must be centered under the faucet. For splashing and for aesthetics. Exceptions are rare. Good luck! I hope to see a pic and get more specific!

Hi. I hope the counter is thick enough to take the weight of the sink and water. atleast 25mm to drill in the undermount sink clips. Drill clips are available easy, you can look up Blanco and Franke EL undermount clips. If the counter is thin, you risk cracking while drilling, in which case it is better to use epoxy sink clips. A brand you can find in India is Solartime. They are expensive but you can get your local fabricator to make you a dozen clips and get them galvanised to prevent rusting. Do remember to apply silicone sealant between the undermount sink and the quartz generously. I know how you feel, things that are easily done in the west can be a pain to achieve in our country, especially places other than major cities.

PS, Is this a Prestige builder property? Pros of going with Sink and Hob on same side: 1- Perceived convenience of the user 2- Hiding the Chimney duct will be easier on the end to end wall Unit 3- Provides a view of the living area to the chef Pros of going with Sink and Hob on opposite sides: 1- Electric points and Gas provisions for Hob and Chimney are already provided for, may not require any changes 2- Separate Wet and Dry zones in Kitchen 3- Guests gets a view of the cooking gas Some of them are listed above, please take a call accordingly. Hope this helps Thanks, Nitin Cornerstone Designs, Bangalore.

The waste from sink will directly drain from the bottle trap. Bottle trap is more hygienic as it doesn't allow any gases from drain into the kitchen/bathroom. The one on the floor is to allow any water (either from overflow or from cleaning the floor) to be drained out.
