Maximum sinks that are available in India fall under the top-mount category or under-mount category. Each of them has its advantages. The top-mount is easier to install, but you will have to put some efforts in cleaning its exposed edges. The under-mount category, on the other hand, has concealed rims but will add unnecessary depth to the sink that might strain your back. The installation process of this type of sink is hefty. It is up to you to select the process of installation that suits you the most.
