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

Hi, there. Your layout sure looks perfect, we would advise you not to make any changes in the plan. But, in the 3D render image we would suggest you to either push the fridge to a lil bit right or left, so you can get a continuous line of upper storage. It would make a good look for the kitchen. Thank you.

Love it or hate it? I am afraid of chips and stains!

Kavita, You may be in luck, there is a quick and easy fix for the eyesore. Look for a product called Self adhesive caulking tape. But please get a decent professional to install it this time. They save such issues. Thanks, Nitin Cornerstone Designs, Bangalore
