New flooring might be needed, a new counter for sure, as well as repairing the base. If ok with these, get a quote to help decide. Will the new size/shape feel odd, as assume it won’t be centered?

Easier and in the long run less expensive to start over. You won't get most fabricators to work on a used top as there is nothing in it for them, except the potential lose for breaking it. The cabinets are most likely the same unless you are going to DIY.

A gut redo requires planning with a kitchen designer.

Exactly what are you wanting to accomplish? Is it just reconfiguring the island or do you want to do more renovation in your kitchen?

I think your cabinets are beautiful. I wouldn't change it unless it's really bothering you. Some people definitely don't like the two level islands.

What's on the other side other than a sink?

I need a better icture of the island to show the sahpe and you need to provide a lot more info . First what do you mean by cutting down ?

millworkman is correct. I get this call occasionally and have yet for it to be cost effective.

the wood is nice enough from the point of view of aesthetics...but if you have a space hogging double sink/ lack of drawers and so want a better island w single sink/ more counter on one level...a stack or two of drawers then a NEW island can be worth it. your oven stack is taking counter room on the perimeter so to get more from the island can be a justified goal. its all about the details....how would you configure and does the budget allow what needs to happen.

I think we are more interested in this conversation than the OP

@HALLETT & Co. I agree. Typically on this forum, when the OP can't be bothered to write anything, they can't be bothered to return.

So long OP
