That is an under mount tub and the black top is the material that they used for the counters. Check the Kohler underscore tub. Go to a local tile showroom with the picture and they should be able to give you similar tile options.

The tub deck is a solid surface material, probably engineered quartz, with an undermount tub. Kohler makes a number of undermount versions; you'll have to see which ones fit your space. As for the tile, Fireclay Tile makes a thin brick product that's quite similar to the one in the photo in a "Snow" colorway.
