Inspection openings
Access to supply and drainage lines
When tubs or on-wall installations are covered with tiles, it becomes difficult to access the supply and drainage lines for maintenance or repair. As a consequence, these areas must have corresponding inspection openings.
The metal frames for this purpose frequently interfere with the aesthetic appearance of a design, especially when the covering uses high-value tiles or natural stone. The frames stand out even more when they are not in the same shape as the covering material.
