With money and time, all things are possible.

I'm not really understanding the possible limitation: You may have to lower the drain to accommodate the deeper sink... but I don't see that as being a big deal.

Think it is a great idea!

I was told by a salesperson at the store that the waste drain in a kitchen is a different size pipe. Right now there is just a hole with no pipework done yet, but having to replace the waste line sounds expensive. So I'm wondering if the salesperson was wrong. (I hope!)

The trap in a bathroom sink is often 1.25" while the trap for a kitchen sink is 1.5". However, both traps then connect to a standard 1.5" drain pipe.

You will have to replace the trap (you would be anyway...) but that is cheap. You might have to lower the point where the trap connects (which shouldn't be terrible, but will add a little cost to it.).

Thanks, Jake. That doesn't sound impossible.
