Laura, I have found over the years it is not a good idea to translate that ideal picture you have in your mind into what you will supply in a rental facility.
Most guests are wonderful but, there is always that one that will have you scratching your head wondering how they ever made it to adulthood!
In the house I have black granite counter tops and I think they are wonderful....you don't have to worry about scratching the surface or using a cutting board and, maybe I am just a bit more careful than your average guests but I have never managed to break anything on them. I started with the same out in the listing cottage and every 4-5th guest would manage to break plates or drink glasses invariably ruining the set! So I have gone back to a timber counter-top and I use a plastic counter-top protector. It is heat resistant and comes in 2ft by 12ft rolls and costs a minuscule fraction of what counter-top replacement costs......
This piece had been in use for about 6 months when this photo was taken and sure, it needs a rub with oil to make the score marks disappear....but it has solved my breakage and damage issues.
A copper sink will look good but will not be as durable as stainless steel, there will always be that guest that will want to rattle the cutlery around in it until it looks like it came out of the trenches in World War 1 .....and no guest is going to look back on you with kindly thoughts because of your copper sink.
Keep it simply, after the cracking of my second glass shower door when a guest has let the flexible shower head hit it, I installed a motorised roller blind similar to what we have in our main bathroom to serve as a rigid shower curtain......
Guests love it and I have not had a problem since...and it always looks clean, unlike glass shower doors, it's battery operated so there are no mains power issues. It was my 'practical' solution.
I understand you want to provide a lovely unique listing, but Laura, the problem with copper is, it is soft, it will dent in something is dropped into it, just not practical. Butchers block is designed to look chopped into but it is not designed to have food colourings engraved into it forever more.
Try to keep it simple and practical.
Cheers........Rob
