We tiled ourselves (upgrading the kitchen in our old house. Everyone thought it was great. Unfortunately, we hated it until the end) If you have it done, the professionals would need to know how to do it. If you want to do it yourself: Tile material, as you wish. Preferably small (we had 10 x 10, somewhat rustic) Adhesive: 2-component adhesive. Such is also used in laboratories, it is acid-resistant. The mixture is a bit thick. I would lay out the tiles in advance. I cannot remember if the grout was the same or something different. Cleaning is not a problem, as the grout is very durable. The only problem was the front edge, the scrubbing strip: We nailed one made of wood, which wore out quite quickly.
