Are you wanting an above-counter vessel style sink, an integrated one-piece sink and countertop, or a conventional drop-in sink?

A vessel/bowl style will not require any cutting down into the countertop, other than the one hole for the faucet.

1. A vessel sink should have a template to cut the hole. If yours doesn't put the basin on the table and outline the hole to cut.
2. Make sure that your faucet will fit in -- before you cut (and again should have a template) behind or beside your basin.
3. The plumbing water lines are easy since you already have the pieces from the old sink. Test those to make sure they fit on the new. If not take the new faucet to the plumbing store and let them help you out with fittings.
4. The pipe on the original may not fit on the new basin. That's okay; use a flex plastic pipe. There are kits! Just ask the plumbing store how to connect and they will give you the pvc cleaner and glue and will probably show you how.

Good luck.

thank you "Hometalkers"!! i'm feeling more confident now! wish me luck!
