PROBLEM TO BE SOLVED: To provide a tile block for corners and tile blocks for side walls in which dust or scale is hard to accumulate in a three dimensional corner or a side part where these tiles are laid and which are hygienic and easy to clean. SOLUTION: The tile blocks 10 for corners are attached to three dimensional corners where three wall faces on which the tile blocks are laid cross orthogonally to each other. The three back faces of the tile block cross mutually at right angles to be integrally formed. All these three faces are formed flat and the front face 11 is formed to have a spherically recessed face as its feature. Since the three dimensional corner can be covered with the front face 11 of the spherically recessed face, dust or scale is hard to accumulate in the three dimensional corners. Further, since the front face 11 has a spherically recessed face, edges of a brush or the like can surely reach the depth and hence, it can be easily cleaned.
