Granite is a wonderful natural stone which adds on the aesthetics to kitchen, vanity, fireplaces and many other such applications. But the great challenge here is to select the granite color, as granite comes is different colors providing multiple options to suit your wall, flooring and cabinets. But once one freezes up on granite color, the next question which arises is the granite slab thickness which are normally available in 2cm (3/4″) or the 3cm (1 1/4″) with tolerance of +/- 3mm.
The edging is one of the point in consideration in determining granite slab thickness. The edging on 3/4″ inch thickness slab can be built up to 1 1/2″ or 2 1/4″. While the edging on 1 1/4″ inch thickness slab is left as it is and if required can be built up to 2 1/2″.
The 3/4″ granite slab is required to be put up on plywood or other backer, whereas the 1 1/4″ granite slabs do not require such support.
The 1 1/4″ granite slab costs more than the 3/4″ granite slab. The costs to get the edges done on the 3/4″ granite slab are higher. So the costs nearly remain the same for a countertop with either thickness.
The 3/4″ granite slab weighs 1/3rd less than the 1 1/4″ granite slab. 3/4″ granite slab is a good option addressing to weight concerns and needs to be installed properly to prevent cracks.
