    Default UndermountSink & Stone Benchtops

    We're getting a new kitchen installed shortly and have had a bit of conflicting advice from the kitchen installer and the stone company.

    The kitchen installers put all the cabinets in and are suggesting to attach the undermount sink to the substrate. Then the stone people put the benchtop in on top.

    The stone guys have suggested not to attach the sink to the substrate so they can line the sink up better with the hole that is cut. They then silicon the sink to the benchtop.

    What is the normal way to do it...my thinking is that it's probably going to be better getting the stone company to attach the sink as they are more likely to get a more snug fit. Attaching it to the substrate seems a bit more hit and miss.

    Thoughts appreciated.

    I havent had experience with this but as noone else has answered I offer my two bobs worth.
    I would let the stone company do it. they have offered and you then are sure it will be centred perfectly. Maybe the kitchen Co. wants to place the cut out in the carcass to finish their work. If thats the case speak to the stone Co and ask if they mind marking and doing the cutout- I'm sure they wont.

    Hi, have done this myself, and std way is for the stone company to mount your sink for you. I bought my stone without installation, so had to get advice on install of the undermount, and they either used silicon with a weight on top to allow cure, or a 2 part epoxy to adhere the sink surround onto the underside of the stone top. Personally I got a little carried away, and siliconed and also epoxied afterwards, but only coz I had the epoxy to do it.

    Definitely let the stone cutters attach the sink directly. Much nicer look and a better seal to keep water from running under. It's the standard procedure here.
    Cheers,

    As an aside, did you do the cutout yourself? Did you do any cuts or joins at corners (L shaped corners I mean)? Would you DIY again? Any problems manouvering the slabs, given their weight? What sort of stone?
