Can I reuse my sink during a kitchen renovation?
Most commercially purchased drop in sinks as easy to remove and reinstall.  Only custom built ins are not so easy.
Commercial drop ins are held in place by clamps up under the sink and or silicone RTV.
When removing in future the clamps are loosened and the RTV cut away.  The sink pulled and cleaned then reused.
Check the sink you plan to purchase and see how it is secured.
