What is a disadvantage of lavatory carriers mounted on stud or masonry walls?

Mounting lavatory carriers on stud or masonry walls can indeed present concerns related to structural strength. When these carriers are not securely anchored or if the wall structure is inadequate, there can be issues with stability, particularly when the lavatory is subjected to various forces such as user weight or movement. This instability can lead to the potential for failure in the mounting system, which poses safety risks and could damage the wall itself.

Using appropriate materials and ensuring correct installation practices can help to mitigate these issues. However, structural integrity remains a primary concern, as an insufficiently supported lavatory can result in a compromised installation, leading to costly repairs and safety hazards. Therefore, careful consideration of the wall type and appropriate reinforcement is vital when installing lavatory carriers to avoid structural weaknesses.
