advantage is easy to clean , looks reach appearance and the disadvantage is getting cold and needs to clean frequently

Advantages are beauty and durability. Disadvantage is not suitable for kitchens as acids can etch surface. With a honed (matte) finish, this is minimized. Best to seal using a quality sealer like HMK-S34 Impregnator.

Marble is perfect for a bathroom countertop. Marble is a calcium based stone so it is not usually used in a kitchen where acids can etch marble. If you like the old world look of marble kitchen countertops, have your marble "honed" to remove the polish, thus giving you a satin look. Combined with a quality sealer like HMK-S34 Impregnator, marble may be an option for some people. Powder bath counters and master bath vanity tops are very often made out of marble slabs.

There are few or no major health risks associated with marble countertops. Marble countertops are an excellent choice with regard to health and safety because the solid marble material doesn't absorb liquid or food juices readily. Marble can also be thoroughly cleaned after each use, reducing the opportunities for bacteria to grow on the surface. Remember, though, that polished marble can be scratched or dulled by abrasive cleansers, so be sure to use only a cleanser specifically intended for use on marble.

Marble countertops are porous and susceptible to stains, but they are no potential thread to mans health.

No. If sealed with a quality sealer like HMK-S34 Impregnator, this seals the pores of the stone and protects against stains and water damage.

Marble counter tops are a great investment in any home. Not only do they look great, but with proper maintenance they can last a lifetime. Marble is a hard stone and as such is resistant to scratching, heat, water and staining. Nearly any cleaner can be used on a marble counter top. But if you are really concerned with making your counter top last indefinitely, choose a non-abrasive cleaner. These are the most common types of cleaner and can be purchased at any grocery store.

The best cleaner is a neutral stone soap like HMK-P24. Combined with a quality sealer like HMK-S34 Impregnator, a marble counter will last for years and years!

Daily cleanings should include sweeping and damp cloth wiping. A variety of daily cleaners are available; my own favorite is Dupont Stonetech Revitalizer, but there are many others. Miracle Sealants makes a good one, too. To really get the tile clean you will want to use a mildly acidic cleaner but these should not be used frequently as over time they will damage the grout, the base mortar, and perhaps even the tile. If, after installation, your tile looks icky and dirty and has white residue, you will need a grout haze remover. Follow the directions carefully to minimize damage to the grout. Significant buildup of wax, sealant, etc., can be removed with Citristrip, available at most large hardware stores. After using haze remover, Citristrip, or other harsh products, you will want to reseal the tile. I use Miracle Sealant "511 Impregnator."
