Make your own natural stone sink?

[Mollli]

Hello! I'm considering having natural stone sinks in the bathroom when we eventually start building our house. I've seen that it's not super expensive to buy these, but I think the more you can do yourself, the more fun it is. Putting your own stamp on things.

To the question, what do I need to mill the stone to begin with? What do I need to polish the bowl, do you need any surface treatment in the bowl etc.?

Very grateful for answers if someone has done something similar.

Regards

Well, sounds like an awesome fun project!
Anyone here who has done it and can show a picture?

What do you think could be used to achieve that final sanding/polishing that he doesn't quite nail in the clips?

Wet sanding in seven different steps was what the hand sanders used when I worked with stone countertops. I did not personally work with hand sanding or polishing.
