Things to consider:

  • Most "new location" sink installations require opening of the wall to relocate drain and water-supply plumbing, you do not mention this but need to prepare for it.
  • flexible drain tubes are more prone to accumulation of material (clogging) so you may want to consider adjustable tubular slip-joint drain pipes. You do not mention a trap, these are necessary for safety and code compliance.
  • The upper flange of the drain assembly (where the drain assembly meets the sink hole) is most often sealed with plumber's putty, you may need some.
  • The ability to fasten the sink to the wall with those "coach screws" is totally dependent on wall construction. You may need special anchors or other reinforcement to ensure the attachment is strong enough.

Terminology and methodology is particular by geographic area, so if this does not make sense then we hail from different parts of the world.
