This is exactly the negative edge baseboard we have in our home. The look is very nice, but as it is drywall that meets the tile, it is easy for cleaning crews to damage the wall. And, the tile installers did not always take the tile to the wall therefore we have some cracking grout lines near our walls. We are debating a robotic vac/mop for cleaning the tile floors. Otherwise we are using a string mop. It's a big job! Anyone else have any ideas?
