How to Install a Bathroom Sink Faucet
A step-by-step guide for DIY faucet installation.
Before You Begin: What You’ll Need
The first step to prepping your space is to gather the necessary tools for your bathroom sink faucet installation. Most often, you’ll need:
• Adjustable wrench or basin wrench
• Bucket and towels
• Plumber’s putty or silicone sealant
• New KOHLER® faucet
• Flexible supply lines (if not included)
• Cleaning cloth or sponge
• Teflon tape
• Safety glasses and gloves
• Flashlight or headlamp for visibility under sink (optional)
• Caulk and caulk gun (if sealing around base)
Consult the product manual that comes with your bathroom sink faucet to see if any other additional tools are required or search KOHLER service parts to find a specific part.
Step-by-Step: How to Replace a Bathroom Sink Faucet
Styles
KOHLER bathroom sink faucets come in a range of design styles to seamlessly integrate within your space, including:
Traditional
Timeless style that complements a classic aesthetic
Contemporary
Sleek silhouettes for modern bathrooms
Transitional
Versatile designs that complement both traditional and contemporary spaces
Installation Types
Ensure you select a faucet that will fit your existing faucet holes by measuring the diameter of each hole with a caliper or tape measure. For multihole installations, measure the space between the centers of the left and right holes to determine the faucet center. KOHLER installation styles include:
Centerset
Includes spout and handles mounted on a singular base plate
Single-Hole
Combines the spout and handles into one singular unit
Wall-Mount
Installs directly onto the wall so spout and handles hover over the sink
Widespread
Spout and handles are installed separately from each other
