there is many types of support to be used for counter top for long lasting work... as ... 1) brick wall which takes 2" , 4" or 6" thickness space which is not good for below space as we will waste space for storage under counter... this is used where heavy material is used on top of counter for cutting any food items... 2) marble support... which will take 35mm thk space double support... 3) furniture base if the kitchen working person is using the sink properly for washing purpose and the gaps between the sink and counter top has to be sealed properly for leakage free to avoid any damages for below storage, as i will not prefer this in other area... this can be used only in foreign countries...

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

Hi Abinash Here are a few ideas for your basin area: - De-clutter the counter top. Remove all unnecessary items and store the rest in baskets under the counter. If possible, put up a wall mounted soap dispenser. - Add baskets under the counter where you have some storage space. They'll look cohesive and you can't see the mess. - Add a bigger mirror to the wall, a wider one. - Add a light right on top of the mirror. Also, if you are looking to treat the windows quickly, simply add full height waterproof fabric curtains. Please contact us for any design discussions. Best, The Lazy Owl Designs

Granite is more suitable for Kitchen countertops .
