Professional Guide to Bathroom Sinks and Plumbing by SeaStack Plumbing

Types of Bathroom Sinks

1. Pedestal Sink:

1. • Design: A classic option that stands on a pedestal, perfect for smaller bathrooms where space is at a premium.

   • Plumbing: The plumbing is hidden within the pedestal, creating a clean and uncluttered look. Drain and supply lines are typically run through the wall or floor, ensuring seamless integration.

2. Wall-Mounted Sink:

   

   • Design: Attached directly to the wall, this sink leaves the floor space beneath free, creating an open and airy feel.

   • Plumbing: Requires strong wall support to hold the sink securely. Pipes are routed through the wall, making the plumbing virtually invisible.

3. Vessel Sink:

    

   

   • Design: Sits on top of the counter like a bowl, adding a stylish and contemporary touch to the bathroom.

   • Plumbing: The drainpipe runs through the countertop, and the supply lines come from beneath the counter, providing a neat and organized appearance.

4. Undermount Sink:

   

   • Design: Installed beneath the countertop for a seamless and modern look, this sink is easy to clean and maintain.

   • Plumbing: Requires mounting hardware to support the sink. The drain and supply lines are hidden under the counter, enhancing the sink’s sleek design.

5. Drop-In Sink (Self-Rimming Sink):

   

   • Design: Fits into a cutout in the countertop, with the edges resting on the counter for easy installation and a traditional look.

   • Plumbing: The drain and supply lines are routed through the countertop, providing efficient and effective plumbing.

6. Console Sink:

   

   • Design: Similar to pedestal sinks but with legs that support the basin, offering both style and stability.

   • Plumbing: The plumbing is usually exposed, allowing for decorative plumbing fixtures that add a touch of elegance to the bathroom.

7. Integrated Sink:

   

   • Design: Molded as part of the countertop, usually made from solid surfaces like quartz or marble, for a cohesive and high-end look.

   • Plumbing: The drain and supply lines run through the cabinet beneath the counter, maintaining a streamlined appearance.

How to Plumb a Bathroom Sink

1. Assemble the Sink Components: 

• Install the Faucet: Attach the faucet to the sink according to the manufacturer’s instructions, ensuring a secure and watertight connection. 

• Install the Drain Assembly: Apply plumber’s putty around the drain opening, insert the drain flange, and tighten it from underneath to prevent leaks. 

Connect the Water Supply Lines: 

• Attach the Supply Lines: Connect the hot and cold water supply lines to the corresponding faucet inlets using adjustable wrenches to ensure tight and secure connections. 

• Connect to the Shut-Off Valves: Attach the other end of the supply lines to the shut-off valves beneath the sink, making sure the valves are securely connected to the water supply pipes. 

Install the P-Trap: 

• Assemble the P-Trap: Connect the P-trap to the drain tailpiece coming from the sink, ensuring that all connections are tight and properly aligned to prevent leaks. 

• Connect to the Drain Pipe: Attach the other end of the P-trap to the wall or floor drain pipe, ensuring a snug fit to maintain a water seal and prevent sewer gases from escaping. 

Test for Leaks: 

• Turn on the Water Supply: Open the shut-off valves and turn on the faucet. Check for any leaks around the supply line connections and drain assembly, making adjustments as needed. 

• Inspect the P-Trap: Ensure that the P-trap is properly sealed and not leaking, tightening any connections if necessary. 

Secure the Sink: 

• Mount the Sink (if applicable): For wall-mounted or pedestal sinks, ensure that the sink is securely attached to the wall or floor using mounting brackets or anchors. 

• Seal Around the Sink: Apply a bead of silicone caulk around the edges of the sink where it meets the countertop to prevent water from seeping underneath.
