Cutting concrete.

Hi all!
I have an old triple concrete laundry tub, which I want to make into a double. Was wondering whether anyone has any brilliant ideas on how to cut off the extra sink area.
Thanks in advance.

I have a free double in tamworth if you want it!

dont forget to wear a dust mask

Thanks Pulse but I don't think it would be quite feasible to get it to Queensland!
I'm going to try the angle grinder! Just bought a new one so should be a fun christening!
Thanks for the help.
