The sink will outlast the fashion of the counters, no problem. You will get tired of whatever you put in far sooner than it will wear out. There is nothing that you will ever choose that is a completely permanent installation. Infrastructure has gotten in the fashion merry go round along with harem pants.

Thank you for your response but this is a sustainability issue. We do not intend to replace the counter.

Wow, you're young. There are tradeoffs to all decisions, even if you do not realize it. Intents don't equal reality a majority of the time.

You can replace an undermount sink in stone, if need be. It will not be cheap or easy. If you want cheap and easy, that is stock laminate from a box store, and a cheap drop in sink. All done DIY. 20 years from now, when your realtor tells you that this is all hopelessly out of fashion and must be replaced completely if you have a hope of selling, you'll remember this conversation.

Thank you for your response. But please, I'm looking for technical trade advice on the best installation of this type sink designed for ease of replacement.

Thank you, that's good to know. However, our sink will be very heavy - fireclay. Is there a system you can recommend for secure bracing and also easy removal (or at least removal without causing a lot of damage.)

I have a Koehler Whitehaven apron front cast iron sink. My last cast iron sink lasted 20 years. Actually I am still using it in a basement kitchen. My Whitehaven should last as long, hopefully another 20 years - fashion in kitchens not as big a deal where I live so sink and counters both hopefully good for the long haul.

Use another strap if it'll make you feel better. They're inexpensive.

IMO apron front sinks are already becoming a dated look it is a never ending merry go round just get what you like and enjoy it, chances are when the time comes you won’t be able to find a sink those exact measurements .

You don't need a sink with the same dimensions, you need a sink that's the same or a little larger.

TM, although Joseph has clearly displayed his expertise, finding a professional in your area to do this well will be key - there aren't that many around willing to attempt this type of work.

I've never heard of anyone worried about 'sustainability' of replacing a sink.

I have a sink with epoxied granite "clips" and a sink with threaded inserts and metal clips.

I think the OP's request is unusual, my response is make a cradle for the sink, with adjustment screws. Would be able to change out sinks as frequently as desired, if a solid silicon gasket was used.
