More pictures showing how the border works in the rest of the adjacent room would be helpful. Also, a sketch that shows how the current border would be affected would be helpful. I would love to save the border. Or adjust it appropriately.

Concrete needs 'expansion joints'. Which means a massive slab on the wall is still going to have joints. On the floor the same issue will occur. Finished concrete surfaces are a lifestyle finish not a 'cheaper than tile' finish. Finishing concrete is expensive and it must be worked by a finishing concrete expert (more of an artist than a handy man). Concrete is porous. It is MORE POROUS than marble. I STAINS easier than marble. It ETCHES more than marble. Concrete as a 'finish' is considered a 'living finish'. It is always changing. It is always staining/etching. It is a whole lot of excitement to live with! If you love a surprise every single time you step into the shower or every time you make dinner or every time you step on the floor in bare feet then concrete is the finish for you. A HIGH END polished FINISH on concrete can be $7-$25/sf. The only thing that slows down the staining and etching (floors) is epoxy ($5/sf). A concrete counter top is stunning...and annoying...and surprising...It will show little spider cracks (as will all of the concrete surfaces). The finish on the counter top must be 'food grade' which makes it less resistant to things like water, orange juice, olive oil, red wine, white wine, etc. And you still need a better level concrete finisher. They can be hard to find. Ask yourself how much you want the imperfection of a living concrete surface? Can you handle the changes that you will notice on a weekly basis (if not daily...it depends on how much of a 'Type A Personality'.

Sorry to say but Celadon is probably correct. You can decide how much you want to continue with a company that does not support their customers.... Daltile will be more than happy to take you on as a customer.

Im looking for kitchen floor ideas. I was going for the same look in the kitchen and living room, but my laminate floor got water damage. Looking for golden oak vinyl plank that looks like the laminate I have in the living room or another option.
