Is the inset drain able to be tiled?
Pure grating pattern is designed to be filled with tiles indeed. It features of 12 mm deep channel, so if you're tiles are not thicker than that, this product will be suitable for you. At the end of the day there's only grap between the grating and rest of the floor visible, so that's very minimalistic design.
If you're tiles are thicker than 12 mm you should go for Showerlay Wiper 800 x 1200 mm Line Invisible. It doesn't have any vertical frame, so there's no requirement for finish material thickness. You will need to aesthetically cut the tiles probably with water jet to avoid sharp edges.
