Sink Options
Have fun with your bathroom update. Sinks are available in a wide variety of materials and styles. Choose a sink material that matches the rest of the design in the bathroom or add interest with contrasting colors and sink types.
Sink materials:
- Composite – $300 to $600. Durable and resistant to chipping, composite sinks are functional and can fit into most homeowners' budgets.
- Stainless steel - $100 to $800. Stainless steel is durable and versatile, adding a modern twist to your bathroom.
- Quartz - $800 to $1,200. Pricier than other sink materials, quartz sinks are strong and resistant to stains.
- Solid surface - $2,100 to $3,400. A man-made material that can mimic the look of quartz and granite, solid surface sinks require installation by a pro.
Sink styles:
- Vessel sinks – sit right on top of the vanity counter.
- Surface-mount or drop-in sinks – fit right into the bathroom counter.
- Undermount sinks – mounted and installed from underneath the counter.
- Pedestal sinks – free-standing, these sinks are supported by a column.
Easy Steps for Sink Replacement and Installment
1. Materials and tools:
- Putty knife
- Silicone caulking
- Basin wrench
- Plumbing sockets and wrenches
- New faucet and sink
2. Purchase a new faucet and sink, being sure to measure the existing sink and vanity first for accuracy and fit.
3. Turn off the water supply below the sink vanity.
4. Using the basin wrench, disconnect the drain lines and water supply from the faucet. Use the putty knife to loosen the caulking around the sink, then lift out the old sink.
5. Apply the silicone caulking around the bottom lip of the new sink to create a solid seal so water can’t leak in. Lower the sink and place it in the correct position.
6. Install the faucet, using lock nuts or silicone to keep it secure.
7. Install the drain kit and connect the water supply lines.
8. Apply more caulking around the top of the sink where it meets the wall to seal any gaps. Let dry for 24 hours before turning on the water and checking for leaks.
