Hi there, did you mean to attach photos? I don't think they posted. I know this is from a while back but I'm interested to hear what you ended up choosing.

Hello Rola, You can go for a slightly bigger one upto 21 inches. See if you likes sinks with drain board. Thanks, Amit Cornerstone Designs Bangalore

Madam Your options are ok.... From dimensions point, few things to take care: Your Existing platform depth, you need minimum 21 inches depth for Modular one... New Hood/hob will need 60*60 cm space.... From there you can finalize your sink position/size.... Sink size usually are from 380mm to 600mm, check your window size first!! Since you are removing the old door, plan wall shelves parellel to base cabinets (below existing countertop) Wire basket's are usually from 300 mm to 600 mm size, , based on your lengths it can be further discussed... On the other side there is an RCC shelves which you may have to remove for proper look......

the sink should be at 33" from the floor. your countertop height will depend on if you're using a top mounted or insert sink
