How to install wall mount corner sink?
The arched notches in the rear skirt are intended to accept heavy bolts with rubber pads and washers. 


Be sure that you have solid backing where the bolts will need to go. Install two-by lumber, wide face forward, between studs where needed. Be sure they're well anchored. 
Finish your room. Paint should be complete and well cured. 
Install the sink by carefully locating the bolts to align with the sink notches. I'd put rubber or plastic sleeves over 7/16" bolts, and use neoprene rubber and stainless steel fender washers to secure to the inside face of the sink skirt. Leave the bolts about 1/4" loose when hanging the sink, the snug them slightly against the skirt. The bolts should be piloted properly and extend at least 2" into the wall. 
Optionally caulk along the wall. Use the smallest bead necessary to create a good seal and nice appearance. An acrylic with silicone should last well and is paintable. 
If the drain assembly that comes with your faucet doesn't work out, look for a standard 1-1/4" assembly with full-length threads. Otherwise it's a typical P-trap installation. That's well covered in other questions on SE and throughout the internet.
