2cm granite material is generally less expensive than 3cm material.
Not all granite countertop material will be available in 2 and 3cm…3cm will be more widely available.
Fabrication of 2 or 3cm material is generally the same in the cutting phase of the fabrication, but 2cm can require “lamination of the edge”(a strip of granite glued on the underside of the edge-side to give it a thicker look), which is an additional charge.
2cm with no lamination restricts the amount of different edges and or the profile of the edge one can fabricate on said material.
3 centimeter granite is just that; thicker. Thicker material has greater strength.
There is no difference in the care of either thickness of granite countertop.

Please consider when purchasing your granite countertop.

Sealing granite countertops is recommended once to twice a year, depending on traffic and use. What you are doing when you “seal” a granite countertop is putting a liquid chemical that is thin like water, on the surface of the top; that will sink into the pores and create a barrier to other thin liquids like water, hot grease, red wine, or any other liquid that could stain…it’s a liquid repellant. All granite has pours or is porous. All granite has little fissures and pits all over it…many are microscopic, some you can see with the naked eye(Bianco Antico Granite).

The procedure we have found to be good when we seal is a simple one. I won’t recommend a sealer by name but the Home Depot has this inexpensive one in a small black bottle…it says “granite sealer”. I wet my countertops with this very liberally, take a paper towel and spread it around in a circular motion – as to spread it evenly on the tops; not to wipe it up. I let it sit for 5 minutes and then wipe the tops down with an old towel. Let the tops sit untouched for a half-hour then wipe them down again with that towel.

THE MAKE-SURES:
Make sure that before you use a sealer, you clean the countertops thoroughly with a degreaser like 409 mixed with water – ten parts water to one part degreaser. Make sure that after you clean the countertops and they dry that you wipe the countertops down with a damp rag with no cleaners, just water so you get any excess cleanser off the tops ( i.e. the 409 residue). BEFORE YOU SEAL – Make sure you let your countertops dry for a couple of hours – when you cleaned the tops, you got water in the pours – you want that to dry thoroughly before applying the sealer. Wear rubber gloves when using sealer.

I hope that this helps you when considering granite countertops as a part of your home, or when going to seal your countertops in the future.

Dry climate vs. Humid climate

Particle board is very susceptible to penetration by moisture.  If you buy a new sponge from the grocery store, it is normally dehydrated and dry.  When you put water to it, it expands as it sucks in moisture.  Particle board acts very similar.  Plywood is also affected by moisture but at an extremely much lower rate.  Plywood shelves can warp over time but particle board shelves will sag or bow in the center  If you live in a dry climate you will have better luck with particle board cabinets but overall a plywood box/ solid wood frame cabinet is going to be a sure bet with any situation/ application.

New Counter tops

Want to have your old counter tops replaced with new ones?  Check your cabinets.  If your cabinets are particle board and you have ever had a plumbing leak under your sink basin, you may be surprised to hear that your cabinets could be starting to crumble and fail from the bottom.  Plywood cabinets have a much less risk of compression due to their bigger resistance to water and compression  Make sure that you inspect your cabinets prior to getting a heavier countertop installed ie granite/concrete.  Bring this up to your installer if you have any concerns…

When you are considering your new kitchen, keep these points in mind.
