I've had them in 6 different homes. I hate them. Everything (even softish plastic) breaks when it drops on them. They hurt my feet, my legs, my back, my butt. They hurt my head most of all, because I'm working so hard to understand why people like them. Sure, they are durable (aside from the grout, which ALWAYS stains regardless of frequency of cleaning), but durable is not the only factor to prioritize in a flooring choice. The only being in my house that likes these floors is my Saint Bernard, but he doesn't cook...he just lays on the tile for the cool feeling on his furry belly.

I agree with @reddylee. Things break and even shatter when dropped on them. It hurts to stand on them for any length of time. They aren't the easiest to keep clean. ... I'm mystified by their popularity, although some people I know have them only because some people they know have them!

I love my ceramic floors. I've put them in both kitchens i've remodeled. They are cheap, the colors are endless, and they are easy to DIY install. (I've done two kitchens and two bathrooms.)

I do some fairly lengthy cooking and baking sessions (6+ hours) a few times a year, and they do get hard on the legs/feet then. I have a gel mat for those days, but otherwise I have not noticed a problem.

As far as grout is concerned: the only acceptable grout color is medium-dark grey. It's going to end up that color anyway, so I just start there and not worry too much about the cleaning. There are apparently additives you can use in your grout now that significantly reduce staining, but since I go grey, I haven't bothered.

We had ceramic for years until our most recent remodel. I'd been drooling over honed marble for a long time and I decided the best thing about having a small kitchen is that you can afford to splurge sometimes on stuff you otherwise wouldn't be able to afford to carry over into a larger room. I'm glad we got it but we live by the beach and tracking sand it wasn't anything we gave a second thought to when we had tile. Now, it's meant at least one refinishing on a high traffic area near the back patio doors which was kinda costly.

Overall, I find the natural stone more attractive, waay more comfortable underfoot and less prone to cracking or breaking when stuff is accidentally dropped. Just, you know, don't tap dance in sand across the floor, y'all. :)

Boy, that cons list speaks volumes. If you are considering a hard floor like tile in your kitchen, live in a house with it for a couple months first. Or perhaps I should say, live with wood and then tile before you decide.

My moroccan-born husband had us both focused on tile, but we spent two months with his mom and it dawned on us that compared to wood, it's awful. Everything shatters spectacularly into smithereens. Your heels get tired. When it is wet you have to mop up puddles right away and warn everyone it is wet, but people still slip anyway and get really hurt.

The beautiful handmade tiles everywhere lost their interest for me, and I can look at kitchen pictures without envy. Wish the same were true of ten foot ceilings...

Longing for the day that we have the time and money to rip out the light-grey ceramic tile that came with our kitchen--which, with two boys and three dogs, shows EVERYTHING--and expose the hardwood that is underneath it. Ah, someday... and I won't miss that dirty, impossible-to-keep-clean-no-matter-how-much-you-seal-it grout one bit.

I've just had Dura-Ceramic installed in my kitchen (A congolum product). It's crushed limestone, so it has a matte ceramic look, but easy on the feet, not cold, things won't break as quickly when dropped and has many colors available. It can be used with or without grout. I recommend using their grout which is stain-proof and ideal for the kitchen.
It also absorbs sound and doesn't sound like your walking on glass. It's been 1 month and I like it so far.
