Very interesting, so maybe you think it may just be a wear and tear problem in a kitchen or a hallway or any other heavy traffic area ? Cow
I have ceramics in my kitchen, hallway and utility room. All 3 areas are high traffic areas as we use the front door to get into the house (hallway), we have to go through the kitchen to get to the back door in the utility room and the utility room houses the dog, dishwasher, washing machine and tumble dryer. I've seen no wear or tear problems in any of those areas yet. Kitchen floor has been down almost 3 years, grout lines are dirty because I used a beige grout rather than a grey. But all of the other rooms appear fine. Grout isn't failing, none of the tiles are damaged despite mine and Mr GRR's best efforts at being clumsy.
My reason for choosing ceramics is because I didn't have a lot of money to spend on tiles. Considering travertine and porcelain cost upwards of £16 a square metre, I chose cheaper ceramics in my house for now, and spent the £16sqm on lovely carpets upstairs
