This is a tough one without re-doing the floors. Could you call a tile store? Maybe they have some type of treatment to 'rough up' the tiles. Also, since you have elders in the home, grab bars placed in well thought out locations might be a good idea anyway, along with skid-free rugs.

Just a little ceramic information to share as a potter. Vitrified simply means the clay has become glass like by being fired to its proper maturing temperature. Usually ceramic tile means it is a lower temperature clay like earthenware or terra cotta. Porcelain is fired to the highest temperature and is more vitrified if you will. This usually means it is less porous to to absorb water and harder. Low fired ceramics with glazes much darker or lighter than the clay body will show chips easier. Rectified has to do with making the edges precise enough to fit smoothly together for less grout lines. So porcelain cost more to produce but it is more sturdy. All clay tiles should be vitrified.

In the Indian brands Somany, kajaria and nitco have a good range of wooden floor tiles. A mid teak wood color goes with most furniture. whether you use the plank format or square tile, it is a must to use spacer and grout. .

Hello Nitin, Thank you, for some excellent suggestions. I would however like to clarify my requirements/dilemma a bit more. 1) The built/carpet area for this 3 BHK is about 1600 sqft (Superbuilt 1960 sqft). What is the appropriate tile size I need to scout for? More specifically, will Ultima-range-like huge tile sizes (i.e. 120x180cm2, 120x120cm2) be suitable for this area? 2) While I am thinking of white (based) tiles, I am not necessarily looking for super-white tones (it gives a bit of a commercial look, and will need extreme maintenance). Something more practical, and with some depth/dimension is what I am trying to identify. Any suggestions? 3) Would you advice that I consider other white-toned flooring options like Terrazzo (Bharat Floorings is having a Cast-in-Situ option, but I am yet to go to their showroom)? Thanks and Regards.
