Hi Lyn and Adel
I'd like to recommend Perla. Not sure where it is made but I've been using it for many years. It heats up water really fast and has a slim and simple design.
Hi Jen
I do have it but my ID didn't mention the risk so I assume it's non-existent. However, I would expect him to touch up on any crack which appears. You may wish to clarify with your ID if hacking would cause cracks.
Hi
Those who are interested to do a pebble wash may wish to consider that the effect might not be an even look. I'm having my foyer hacked up for the second time for a redo. This causes delays and unnecessary stress.
