I was having problems as to what to do with a very old vanity top that i was hoping could be cut for a new sink. I did not want to have to purchase a new top but I wasn’t even sure what material it was and didn’t want to yank it out until I knew. I made a couple calls and was referred to Manstone. I was helped all the way through the project by Craig who was most friendly, helpful, and courteous! Now I have a brand new sink in my old top and it looks great. Thanks Craig.
