Sanitary arrangement comprising a pipe connection piece comprising a pipe housing which delimits at least one pipe channel, and comprising a flange section with a flange surface projecting from the pipe housing, wherein the pipe connection piece extends from the flange surface with a pipe section extending along a straight center axis up to a pipe end, and a spacer comprising a contact surface for direct or indirect mounting of the spacer on a wall structure, and comprising a first stop surface and comprising a second stop surface, wherein the distance between the first stop surface and the contact surface, when viewed in a direction of the surface normal of the contact surface, is different from the distance between the second stop surface and the contact surface, wherein the spacer can be brought into contact with the flange surface either with the first stop surface or with the second stop surface, such that the distance between the contact surface of the spacer and the pipe end as viewed in the direction of the center axis, when making contact with the first stop surface is different from the distance between the contact surface of the spacer and the tube end as viewed in the direction of the center axis, when making contact with the second stop surface, wherein the second stop surface is provided by at least one elevation which projects from the first stop surface, and wherein the flange section comprises at least one recess (15, 16), characterized in that the recess (15, 16) and the at least one elevation are designed such that in a first relative position between the spacer and the flange section, the elevation projects into the recess (15, 16) and the first stop surface can be brought into contact with the flange surface, and that in a second relative position between the spacer and the flange section, the elevation with the second stop surface can be brought into contact with the flange surface. a pipe connection piece comprising a pipe housing which delimits at least one pipe channel, and comprising a flange section with a flange surface projecting from the pipe housing, wherein the pipe connection piece extends from the flange surface with a pipe section extending along a straight center axis up to a pipe end, and a spacer comprising a contact surface for direct or indirect mounting of the spacer on a wall structure, and comprising a first stop surface and comprising a second stop surface, wherein the distance between the first stop surface and the contact surface, when viewed in a direction of the surface normal of the contact surface, is different from the distance between the second stop surface and the contact surface, wherein the spacer can be brought into contact with the flange surface either with the first stop surface or with the second stop surface, such that the distance between the contact surface of the spacer and the pipe end as viewed in the direction of the center axis, when making contact with the first stop surface is different from the distance between the contact surface of the spacer and the tube end as viewed in the direction of the center axis, when making contact with the second stop surface, wherein the second stop surface is provided by at least one elevation which projects from the first stop surface, and wherein the flange section comprises at least one recess (15, 16),
