If you are looking to create a unique and ultra-modern look in your bathroom, a vessel sink is an excellent idea. Vessel sinks are bowl or saucer-shaped sinks that look both old and new at the same time. These types of sinks are not difficult to install; however, there are a few things you should pay attention to when installing so there won't be problems with the plumbing later.
Use a Quality Silicone Caulk
Many problems with vessel sink plumbing can be attributed to using the wrong type of caulk or adhesive when attaching the mounting ring. With a vessel sink, the caulk or plumber's putty get wet constantly, and cheap caulks or adhesive just don't hold up.
When installing a vessel sink, always use a high-quality silicone-based caulk adhesive that is waterproof and won't break down when it gets wet. Allow the caulk adhesive to completely dry before using the sink. If you are unsure of how long to wait, refer to the instructions on the tube of caulk.
Tightening the Drain Too Much
Another common mistake made when installing a vessel sink is the over-tightening of the drain flange. Generally speaking, vessel sinks are not as durable as regular bathroom sinks and can be easily cracked at the base of the sink if the flange is too tight. Secure the flange securely and turn it only about 3/4 to one full turn past hand tight.
