COUNTERTOPS

Above: Almost white natural stone tiles add an elegant touch to a curved countertop. Matching white chair cushions accentuate the clean design. Below: A granite stab countertop typically is made with an edging piece under the top piece. Once the pieces are mortared in place, the joint between them is ground and polished until it becomes almost invisible, giving the appearance of a very thick stab.

Indoor countertops are typically 24 inches deep, while outdoor countertops are 30 inches or deeper. If the counter, top wilt be accessible from both sides, you may want to make it 42 inches or more.

SUBSTRATE

If the countertop will be made of concrete or thick stabs of stone, it will likely not need support other than the counter's walls. However, most other finish materials will need to rest on a solid subsurface that spans the counter and extends 3 inches or so on either side. The most common substrate options are a steel- reinforced concrete stab (see pages 136-139), or two thicknesses of concrete backerboard that are glued together with thinset mortar (see page 132).

FINISH MATERIALS

The kitchen's working surfaces, which may also be used as dining surfaces, should be durable and easy to clean. There are several finish materials that will achieve these goals beautifully.

STONE TILE

Stone tiles of any sort can be used on a countertop as long as they are protected with a coat or two of acrylic seater. Some stone tiles that do fine on a vertical surface may be unsuitable for countertop duty, either because they are not strong enough or be, cause they stain easily. See pages 22-23 for basic information on stone tiles and pages 130-131 for installation. Consult a tile dealer before making your choice.

GRANITE

Large, gleaming stabs of granite make ideal countertops, both indoors and out. Granite is typically speckled or flecked, and it comes in a wide variety of shades ranging from very dark to very light. Cutting and installing a granite slab is best left to professionals. Usually there is no need for a substrate, since the granite slab is very strong. Installers will measure your counter, cut the slab or slabs at their shop, and set the counter. To achieve the illusion of a very thick slab, they may attach a facing piece, typically 2 inches wide, below the front edge of the slab, then grind and polish the seam until you can barely see it
