Install new lavatory faucet and drain. Install new supply line. Install new toilet and shower faucet trim. When installing the vanity. I carefully removed the new countertop from the box and while dry fitting it on the vanity I noticed a hairline crack on the surface of the countertop. The crack is only surface level and does not penetrate through the countertop. I informed the customer of this and asked if they would still like me to install it or if they would like to return it. Customer would like it installed so I set it in place and finished the installation. Once everything was completed I tested each fixture thoroughly. No leaks at this time. Cleaned work area. Customer is satisfied.
