Replacing a bathtub spigot might seem like a daunting task, but with the right guidance, it can be a straightforward and rewarding DIY project. Whether your current spigot is leaking, outdated, or simply not functioning properly, swapping it out can improve both the look and performance of your bathroom. Understanding the basics of how a bathtub spigot works and the tools involved will empower you to tackle this common plumbing update with confidence.

In many homes, the bathtub spigot is one of the most frequently used fixtures, making it prone to wear and tear over time. When issues arise, such as drips or corrosion, replacing the spigot not only restores functionality but can also prevent water waste and potential damage. While the idea of plumbing repairs might intimidate some, the process of removing an old spigot and installing a new one is often manageable with a bit of preparation and patience.

This article will guide you through the essential considerations and general approach to replacing a bathtub spigot. By gaining a clear overview of the task, you’ll be better equipped to decide whether to hire a professional or take on the job yourself, setting the stage for a successful bathroom upgrade.

Removing the Old Bathtub Spigot

Begin by turning off the water supply to the bathtub to prevent any accidental leaks or water damage during the replacement process. Once the water is off, open the faucet to drain any remaining water in the pipes.

Inspect the existing spigot to determine the type of attachment it uses. Most bathtub spigots are either slip-on (also known as slip-fit) or threaded. Slip-on spigots typically have a set screw underneath that secures the spigot to the pipe, while threaded spigots screw directly onto the pipe.

To remove a slip-on spigot, locate the set screw on the underside of the spout. Use an appropriate-sized Allen wrench or screwdriver to loosen the screw. Once loosened, gently pull the spout straight off the pipe. If it is stuck due to mineral buildup or paint, apply a penetrating lubricant and carefully wiggle the spout to loosen it.

For a threaded spigot, grip the spout firmly with a pipe wrench or adjustable wrench and turn it counterclockwise to unscrew it. Protect the spigot’s finish by wrapping it in a cloth before using the wrench. If the spout is difficult to remove, apply penetrating oil and allow it to sit for several minutes before attempting again.

After removal, inspect the pipe for any damage or corrosion. Clean the pipe’s surface using sandpaper or a wire brush to ensure a good seal for the new spigot. Remove any old plumber’s tape or sealant residue.

Preparing the New Bathtub Spigot

Before installing the new spout, verify that it matches the type of connection on your existing pipe. Most new spouts will specify whether they are slip-on or threaded.

If installing a threaded spout, wrap the pipe threads with plumber’s tape (also known as Teflon tape) to ensure a watertight seal. Wrap the tape clockwise around the threads two to three times.

For slip-on spouts, check that the set screw is accessible and that the spout fits snugly over the pipe. Some models require applying plumber’s putty or silicone sealant to the pipe before slipping the spout on, so refer to the manufacturer’s instructions.

Gather the necessary tools and materials before installation:

  • Allen wrench or screwdriver (for set screws)
  • Pipe wrench or adjustable wrench (for threaded spouts)
  • Plumber’s tape (Teflon tape)
  • Penetrating oil (optional, for stubborn fittings)
  • Cloth or rag (to protect finishes)
  • Sandpaper or wire brush (for cleaning pipe)

Installing the New Bathtub Spigot

To install a slip-on spout, slide the new spout onto the pipe until it rests flush against the wall. Align the set screw hole with the pipe and tighten the screw securely using the Allen wrench or screwdriver. Avoid overtightening to prevent damaging the spout.

For threaded spouts, carefully screw the spout onto the pipe by hand, turning clockwise until snug. Use a pipe wrench wrapped with a cloth to tighten the spout an additional quarter turn. Do not overtighten, as this could crack the spout or strip the threads.

After installation, check the alignment and ensure the spout is firmly attached. Wipe away any excess plumber’s putty or sealant from around the spout base.

Testing the New Spigot

Once the new spout is installed, turn the water supply back on slowly. Open the bathtub faucet and observe the spout for leaks or drips. Pay special attention to the connection points at the pipe and spout interface.

If leaks are detected:

  • Tighten the set screw or threaded connection slightly more.
  • Apply additional plumber’s tape or sealant as needed.
  • Inspect for cracks or damage in the new spout.

Test the water flow by running both hot and cold water through the spout to ensure proper function and no blockage.

Removing the Old Bathtub Spigot

Careful removal of the existing spigot is crucial to avoid damage to plumbing or surrounding surfaces. Follow these steps systematically:

Begin by turning off the water supply to the bathtub to prevent any accidental water flow during the procedure. If there is no dedicated shutoff valve, turn off the main water supply to the home.

Next, open the spigot to drain any residual water in the pipe. Place a bucket or towel beneath the spigot to catch drips.

  • Inspect the spigot for visible screws securing the escutcheon plate or the spigot itself. Use the appropriate screwdriver to remove these screws carefully.
  • If the spigot is threaded directly onto the pipe, use an adjustable wrench to turn the spigot counterclockwise. Apply steady, controlled force to avoid stripping threads or damaging the pipe.
  • When the spigot is stuck due to corrosion or mineral buildup, apply a penetrating lubricant around the connection and allow it to sit for 10-15 minutes before attempting removal again.
  • Use a utility knife or putty knife to carefully cut any caulk or sealant around the base of the spigot. This prevents damage to tile or tub surfaces when pulling off the fixture.

Once loosened, gently pull the spigot straight out to remove it from the pipe. Inspect the pipe end for damage, corrosion, or debris and clean it thoroughly with a cloth before proceeding.

Preparing the Connection for the New Spigot

Proper preparation of the plumbing connection ensures a secure, leak-free installation of the new bathtub spigot.

  • Inspect the exposed pipe threads for any signs of damage such as cracks, deformities, or corrosion. Damaged threads may require repair or replacement by a professional plumber.
  • Clean the threads thoroughly to remove old sealant, mineral deposits, and debris. Use a wire brush or a clean rag for this purpose.
  • Apply pipe thread sealant or wrap plumber’s tape (Teflon tape) clockwise around the male threads. Typically, 2-3 wraps of tape are sufficient to create an effective seal.
  • Ensure the tape or sealant covers the entire threaded area but avoid excess material that could interfere with threading the new spigot.

Preparing the connection carefully helps to prevent leaks and ensures the new spigot fits snugly and securely.

Installing the Replacement Bathtub Spigot

The installation of the replacement spigot requires precision and adherence to manufacturer instructions for optimal performance.

  • Align the new spigot with the pipe, ensuring the threads match correctly.
  • Hand-tighten the spigot by turning it clockwise onto the pipe. This prevents cross-threading and damage.
  • Once hand-tight, use an adjustable wrench to tighten the spigot further. Avoid overtightening, which can crack fittings or deform threads. Tighten until snug and resistant
