Calling All Cabinet Installers/Bath Remodel Contractors!

Am helping my son remodel his teeny bath in a pre-WWII bldg. Have ordered a wall cab 18" deep X 24" wide X 24" high (KraftMaid). Have studied cab specs: 1/8" back panel conceals two 5/8" hanging rails (top/bottom) doweled/glued to 3/4" engineered wood end panels; 3/4" doweled ceiling panel; 3/4" doweled floor panel. Contractor will make cut out in ceiling panel to accommodated a bottom mount sink/granite top.

According to KraftMaid the cab should hold 75 lbs./sq. ft. Walls in the bldg. seem to be concrete/mesh or lathe/plaster. Existing wall hung sink is installed with steel plates. Would appreciate any tips on cab modification or on anchoring this cab to the wall so it will hold the weight of granite and sink.

Thanks so much from Madam Goodwrench

If it is plaster you need to find the studs , and using a stud finder most likely want work so just where you want see it use a nail and drive in the wall till you find one then 16" till you find another, i try and use 3" screws for installation of all cabnits.

If this is a concrete wall then you'll need to use concrete anchors, you'll need the anchors and an hammer drill to do this, as far as size of anchors you'll can use 1/4 and that will be plenty, just 2 at the top will do. The screw length on these can be 1 1/2 or 2"

you can also use tap com screws and use no anchos. if you use these just get 3/16 screws and for a length use 2"

For attaching the granite use 100% silicone before you set the granite and let dry
