Hiya. Doing a reno on my bathroom vanity and wondering if I can replace the standard drain with plug with a popup style drain? I'm thinking yes but also wondering if this is something I can 'have-a-crack' at (some videos show it's not difficult)

or is it a plumber job? I'll be replacing the tapware so looking at this as part of the upgrade. Photos just examples. Obviously need to get a matching size.
Thanks
