We understand/have learned the standard overhang off an island as 12″. But we need a longer/deeper one (18″ or more), because I am the shortest family member at 5’10” and we all need the room for our legs. However, our island is finished on all 4 sides with drawers and shelves, so there is no room for corbels or brackets.
We’re down to 3 fabricators who have the Uba Tuba granite slabs we like. They’re differing in price, of course (from $9,000 to $12,000 – we have a large kitchen and a big island).
But where they’re really differing is in their methods, and thus this is where I need your help in sifting through what they’re telling us, about our island and about their templating and installation/fabrication methods, in general. PLEASE HELP US UNDERSTAND AND DISCERN LIES FROM TRUTH!!!
1.a. Will steel rods or plates embedded into the underside of the granite weaken or strengthen the slab at those areas? (the granite is cut out so the steel is flush with the underside of the stone and then the steel is epoxied in).
1.b. One fabricator showed us a steel plate that is about 1/2″ wide and about 1/4″ thick (my best estimate without a tape measure). Is that good?
1.c. Are steel rods (round) or steel plates actually used? Which is stronger?
2. Are these rods/plates installed to support the granite during transportation or do they help support the granite after installation, as in using them to support an island overhang/bumpout like ours?
3. Some always install these rods/plates in the narrow areas in front of and behind the sink. Again, is this support mainly to prevent the granite from cracking during transporation?
4. On our island, if we can get a curved overhang/bump out of 18″ or more at the center, and as I said we can’t use brackets or corbels attached to the island, will installing steel rods/plates on the underside of the granite in the direction of overhang help support the overhang, or are we being sold the idea that it will help, just so they get our business? (the steel would be installed perpendicular to the edge of the island cabinet, starting somewhere over the island cabinet itself – like a beam extending from inside your house, to outside your house to create an overhang or an eave)
5. Has anyone heard that the epoxy used to “glue” in the rods/plates as only being warrented or lasting for 2 years?
6.a. Do clips screwed and epoxied into the granite really hold a vary large, double bowl stainless steel undermount sink strongly enough when the sink is filled with water and pots and pans and dishes and things?
6.b. Has anyone ever installed the undermount ss sink by sandwiching it between the plywood dust cover (with the edge of the dust cover routed out just deep enough to allow the lip of the sink to be level with the dust cover) and the granite slab, without clips but instead with epoxy on the bottom and top sides of the sink’s lip? (this is what our carpenter did in his house….who’s job used to be to install high end kitchens. He swears this is the better way and is only trying to get us to do in our house what he would do in his own house. He thinks the clips are used by everyone just because for the fabricators, it’s the standard thing to do and it’s so easy to do).
7.. Two fabricators always scribe the stone to the wall and any cabinets on the side. The third one charges extra (for our job, $300-$400 more) to scribe, because they usually count on customers having 4″ backsplashes to cover the gaps. Is it standard in the industry to include scribing in the template process?
8. The same fabricator that charges extra for scribing also doesn’t install steel rods/plates at all, but will if we ask him to. But we need to know if the rods/plates are helpful or not in our island overhang situation…..we don’t KNOW if we should ask for them or not!!! (that’s why I’m writing you here in the forum!!)
9. The fabricator in #9 also uses cardboard to template (at least that what I saw in the shop) whereas the other 2 that scribe use lengths of what looks like 1/4″ luanne plywood. Any pros or cons to either templating method?
10. Anything else we should be asking or be on the lookout for?????
