Ceramic usually has a red/brown body, porcelain is either white, tinted to match the glaze [though considerably lighter in tone], or color body/color through. Porcelain is stronger, but for 90% of residential use, ceramic is plenty strong-- consider that glazed tile is the last surviving remnant of many ancient civilizations, and that you can buy ceramics from the time of the Roman empire on Ebay for a few bucks. A couple cautions: if your kids are waaay out of control, the porcelain could be better in that it resists cracks. But if it's properly set and supported, they'ed haved to drop a shot put or the like to crack regular ceramic. I like porcelain for kitchens in case someone drops a very heavy skillet or similar, though. And in the bath, the color body porcelains tend to offer better traction. Look for the CoF numbers on the tile you like [if you can't find it, ask the salesman to track it down]. CoF is Coficient of Friction, and measures grippiness. Higher is better. Try sliding your foot accross a sample, both wet and dry, and never use a tile in a wet location that is at all slippery-- the EMTs won't care about your lovely tile while sliding your naked tush on a gurney because you've taken a tumble.

Dura Ceramic is neither Durable nor Ceramic. Discuss amoung yourselves.

Laura,,,not enough info. either will work fine. usually porcelain is colored all the way through to the underlying clay body. this makes it a better choice if the tiles get chipped or broken (with ceramic, the white clay interior is usually visible if it breaks) otherwise, not a big difference. both work equally well in bathrooms. as far as easier to keep clean,,,huh? they both clean just as well. grout size is determined by the type of tile you get. longer larger tiles require larger grout lines, porcelain or ceramic. Just because the tile is porcelain, doesn't mean you get smaller grout lines than ceramic!

There is some helpful information about Sintered Stone vs Porcelain here: https://www.tenax4you.com/compact-surfaces-sintered-stone-porcelain-compared-s/2092.htm That website has several articles making comparisons between different materials. Might be a page to bookmark and share with others since the properties of natural stone, engineered stone, and other man made materials can get pretty confusing sometimes. Hope the information helps future readers.
