when do we need wall mounted sinks with cabinets for?

So plasterboard on, plasterer should be here hopefully in a week max but wondering, when should I leave over a wall mounted sink with two drawers underneath for the upstairs bathroom?

Check what the lead time really is. If you have space get them on-site now. I had all the bathroom stuff on-site early to allow me to set the pipes, check fittings, sizes etc Also read the instructions. I stupidly fitted the sink first then offered the cabinet up to the sink. Should have been the other way around. 🙄
