How to Install a Bathroom Sink

Instructions showing you how to install a bathroom sink vary according to the type of sink. This article will point you to the illustrated step-by-step techniques you need.

Installing a bathroom sink (also called lavatory or “lav”) can be a relatively easy do-it-yourself job if you have a few basic home improvement skills and tools.
