I have a Blanco double bowl Silgranit sink, it's the best sink I have ever had. It's been installed 7 years now and doesn't have a mark on it. After use I clean and buff up with a cloth, done.
I've been married 52 years and over that time have had every type of sink on the market.
Stainless steel are the worst and scratch from day one. If you don't mind that they do last a long time
Enamel sinks chip and go dull with age.
Belfast sinks, too low and chip, take up good cupboard space, damage wooden worktops.
If you live in a limescale area, composite sinks can be a nightmare.
Don't just go for style when purchasing sinks,ovens,fridges, freezer. These purchases cost hundreds of pounds and it all adds up with the addition of a completely new kitchen.
Your appliances need to meet your needs, be practical, easy to clean and service and won't need to be replaced in a couple of years.
I had my kitchen replaced 7 years ago bought from Wren Kitchens.
Five years later I had a problem with several doors, the wrap was lifting off.
Because I had a 25 yr guarantee with the kitchen and fitting all the doors and anything that could be seen was replaced. I couldn't believe they would do this.
I had a choice of any of the kitchen they were selling.
They were absolutely fantastic and it didn't cost us a penny.
When you purchase your kitchen ask the supplier what their after purchase service is and get it in writing.
Best of luck, hope you find a fab kitchen.
