The directions for attaching wall mount sinks (e.g. https://www.americanstandard-us.com/...9004.pdf?la=en ) show that the bracket that holds the sink is attached over the drywall by lag screws that go into wooden bracing in the wall. It seems to me that the drywall is the weak link in this arrangement. It could get crushed and dented by forces on the sink. Do people ever put a section of wood or some stronger material under the bracket instead of just mounting the bracket on the drywall?
