Never use this service - terribly overpriced, 3rd party contractor FLO FORM is so unprofessional and neither Costco.ca Installation nor FLOFORM provide customer service, only interested in making money and doing what is best for them. Had to pay full price - Over $17,000 upfront, not itemized price list provided so when required refund, they can give you whatever they see fit and you have no idea. I hate my bathroom countertop (has black splotches throughout, sample did not and was not apprised that it might) and backsplash chosen by professional consultant does not match counterop. No communication with either, really horrible experience, would not recommend to anyone. Could have done it for thousands cheaper but sucked in by Costco's reputation for standing behind their products and the fact that they provided plumbing and backsplash removal/instalation while would have had to get separate. Just Cambria/Handstone purchase would have been over $3,000 less going the other way.
