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.

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 Abinash, Correct me if I am wrong in my guess that you liked the basin so much that this entire unit was build around it :) that too in the centre of the room. Jokes apart, the base cabinet doesn't provide a few inches gaps to the user for keeping the foot comfortably while using a hand wash. Have you considered the water proofing and maintenance of this unit as what it appears it is wood with laminated top as of now. Do you have a floor plan, as it is a surprising positioning of a hand wash. Thanks, Nitin CORNERSTONE DESIGNS Bangalore

Hello Vinayak, wpc sheet with acrylic laminate will cost you the same as natural stone like green marble of common shade granite. The second option is more sturdy then the first one .
