    So i have a situation, i would love to install a large kitchen sink in the bathroom

    it definitely looks possible to do, but would i encounter any problems?

    i am looking at a granite mixture sink, something large so i can bathe my infant in if possible. wife cannot bend down to shower her for medical reasons, and i do not get home until much later in the night.

    do they sell a product so that you can keep using a bathroom sized drain in a kitchen sink?

    i am looking at something like this

    if anyone has any good suggestions, please throw it out there for me, i just need something big enough to use as a infant tub.

    Instead of a vanity cabinet, some people are using kitchen cabinets. A kitchen sink is often deeper than those designed for a vanity, and especially with a granite top, the edges would be too narrow to properly support things. I'd go with a kitchen cabinet to get the additional height and depth with lots of choices for drawers, if you wanted them as well. If you shop for vanities, you'll find they also come in various heights, but most are not counter depth like in a kitchen.

    The piping under the sink should not be an issue. It was pretty common for older houses to have 1-1/2" drain piping for the kitchen, bath, and laundry. Current practice is to plumb 2" to kitchen and laundry, but the traps are still 1-1/2".

    A bathroom cabinet could be too shallow, front to back, for a kitchen sink. You need one at least 25" deep.
