Question about cabinets

[Jim Wilson]

Not quite. Most granites are the 170lb/cu ft range; a 3 cm slab weighs between 16 and 17 lbs per square foot. Still damn heavy.

This is dependent on where you are and the prevailing prices of materials and labor. Areas where labor is inexpensive will use thinner material (2cm/3/4") and pay to have someone laminate a drop edge on. Where labor is higher it pays to buy thicker material (3cm/1 1/4") and not have to hassle with the laminated edge.

Once upon a time laminated edges were done all the time. Now the tendency is to see 3cm/1 1/4" a lot. Personally I like the look of the 3cm but it makes for a different cabinet detail, i.e., you have to jump through some hoops a little, to hide/bury the plywood sub-top.

I'm guessing only about 1/2 that. maybe 2/3. like I said, havent had one fall through floor into basement.... yet......

You're absolutely right ... my head math was off. IIRC, the rule-of-thumb formula I picked up at some point along the way for the estimating the weight of granite was .097 of the cubic inches. I don't know if that is standard or not, but it seems to get you in the ball park.

Granite 168 LB's per cubic foot

That coincides nicely with the formula in my previous post for estimating granite countertop weights: (cubic inches X .097) = 167.6 Lbs cf. Weight does vary according to type. IIRC, the black granite, which is popular these days, is denser and runs in excess of 180 lbs cf.

This is about right. It took 3 pretty big guys to lug in our

66 x 36 x 1 1/4 granite top. I guess about 250 lb or so.

Make sure your cabinets are beefed up (not to mention your floor).
