I think that is more about what you like, concrete usually denotes a more modern feel, almost industrial if that is your style do concrete if not find a tile you love and do that.

i love the dark flooring. what is the brand and the colour of the tiles...

You list is all "stone" products. Stone products are natural. The durability is guaranteed with stone. Stain resistant...remove marble and granite from your list. Both can stain and etch and both will do this with "flooring" more than they will with a counter top. Gloss levels all change...but it will take years to do it. All stones have maintenance = homeowner needs to work at keeping stone looking good. Stone = expensive. There is no "benefit" for "reasonable" when working with stone. They all cost plenty of money. Stone is expensive. No way around it. If you want "glossy" that doesn't stain for a "good price" then you have forgotten to mention the BEST option: porcelain tiles. Porcelain will do everything you want for a lower price. Stone is expensive, it can stain (especially "oil" stains) it will "etch" or lose gloss level with certain liquids (acid based liquids will do this) and they all need to be maintained and eventually need repolishing to maintain "gloss". Durable is all you can expect out of stone. The rest of your wish list belongs with porcelain tiles.

Hello April, It's an old wood floor and each slab of wood accepts the stains differently so getting exact match is very difficult. Sanding, staining and repolishing the existing flooring to match the new floor is a likely solution to your dilemma. Its a messy and time taking procedure though. Easier way out would be to check with original vendor if he still sells the same variety. Or request them to visit with some other matching samples. Thanks, Nitin CORNERSTONE DESIGNS Bangalore.
