How to Install a Shower Column

Installing a shower column is a straightforward project that most DIYers can tackle. Here are the key steps:

Tools Needed

  • Adjustable wrench
  • Pipe tape
  • Screwdriver
  • Level


  1. Turn off the water supply to the shower and open the valves to relieve pressure.
  2. Remove the existing shower head and arm. You may need to unscrew it from the wall or ceiling.
  3. Install mounting brackets according to the shower column instructions. Make sure they are level.
  4. For copper pipe:Wrap pipe threads with pipe tape before connecting.
    For threaded pipe:Use pipe joint compound on the threads.
  5. Connect the bottom of the shower column to the shower arm or pipe. Hand tighten and then give an extra 1/4 turn with a wrench.
  6. Connect the shower hose to the column if required.
  7. Turn on the water supply and check for leaks.
  8. Attach the shower head and test the various settings.

Adjust the angle of the shower column as needed. Be careful not to overtighten any connections. Now you can enjoy the flexibility and convenience of your new shower column!

How to Connect a Shower Column to Plumbing

Connecting a shower column to your existing plumbing is a straightforward DIY project. Here are the key steps:

Tools You'll Need

  • Pipe wrench
  • Adjustable wrench
  • Teflon tape
  • Pipe joint compound


  1. Turn off the water supply and open the shower valve to relieve pressure.
  2. Remove existing shower head/arm if still attached.
  3. Clean the existing pipe threads with a wire brush to remove any grime.
  4. Wrap pipe threads in Teflon tape if connecting to a copper pipe. Use pipe joint compound for threaded pipes.
  5. Connect the bottom end of the shower column to the shower arm or pipe. The connection type can vary:
    • Threaded - screw column directly onto pipe threads
    • Slip-fit - insert pipe into opening and tighten set screw
    • Flanged - insert pipe into flange and tighten mounting nut
  6. Use pipe wrenches to tighten connections. Be careful not to overtighten.
  7. Attach the shower head and hose per manufacturer instructions.
  8. Turn on water supply and check for leaks.
  9. Test shower column settings and enjoy!

With the right tools and proper care, you can easily connect your new shower column to existing plumbing.

How to Adjust the Water Pressure on a Shower Column

If your new shower column's water pressure is too weak or strong, adjusting it is quite simple.

Start With the Showerhead

Many shower heads have internal restrictors that control water flow. Locate the restrictor inside the shower head outlet and remove it with needle-nose pliers. This will increase water pressure. If pressure is too high, replace it with a lower flow restrictor.

Check Supply Line Issues

There may be issues reducing pressure in the supply lines:

  • Partially closed supply valve - Open supply valve completely.
  • Clogged supply lines - Disconnect and inspect lines, clearing any blockages.
  • Old galvanized piping - Replace with copper for increased flow.

Use a Pressure Balancing Valve

Many shower columns include a pressure balancing valve inside the column. Turning this increases or decreases line pressure to the shower head. Adjust it gradually until you achieve the desired pressure.

If your shower column does not have one, you can install a pressure balancing valve inline on the supply prior to the shower column. This gives you precise control over pressure.

Consider a Pump System

For homes with exceptionally low water pressure, installing a booster pump system can help. This uses a water pump to increase line pressure to fixtures.

Proper water pressure for a comfortable shower is typically 30-80 psi. By making adjustments at the shower head restrictor, supply lines, and/or adding a pressure valve, you can dial in the perfect pressure for your new shower column.

How to Clean and Maintain a Chrome Shower Column

Regular cleaning and maintenance keeps your chrome shower column looking like new.

Cleaning Materials

  • Mild liquid soap
  • Soft cloth
  • Toothbrush
  • Vinegar
  • Baby oil
  • Chrome polish or wax


  1. Rinse the column with water to remove any soap scum or debris.
  2. Mix a mild soap with warm water and use a soft cloth to wipe down the column.
  3. Use a toothbrush to gently scrub any small crevices or decorative trim.
  4. Rinse thoroughly with clean water.
  5. Dry the column with a soft towel.
  6. For stubborn spots, make a paste with vinegar and water. Rub gently with a cloth.
  7. To restore shine, apply a small amount of baby oil or chrome polish with a cloth.
  8. Buff with a clean, dry cloth.

Preventative Maintenance

  • Wipe down the column after each use to prevent mineral buildup.
  • Avoid harsh cleaners or abrasive pads.
  • Use a squeegee to clear water after showering.
  • Apply a protective chrome wax 2-3 times per year.

With proper regular cleaning and maintenance, your lovely chrome shower column will stay beautiful and like new.

How to Replace Shower Heads on a Shower Column

Replacing a faulty or outdated shower head is quick and easy with most shower column designs.

Materials Needed

  • Adjustable wrench
  • Teflon tape
  • Replacement shower head


  1. Turn off the water supply at the main valve.
  2. Open the old shower head's swivel ball joint. Use an adjustable wrench to loosen the fitting.
  3. Remove the old shower head. Clean any mineral deposits from the fitting.
  4. Wrap the fitting threads with Teflon tape. Make sure to wrap in a clockwise direction.
  5. Screw on the new shower head by hand. Tighten further with a wrench if needed.
  6. Turn the water supply back on and check for leaks.
  7. Turn on the shower column and test the new shower head.


  • Look for shower heads designed for your water pressure.
  • Choose a finish that matches your décor.
  • Look for water-saving models if wanted.
  • Consider added features like massage jets.

Replacing a shower head is an easy project. With a few tools and proper care, you can upgrade your current shower column with a new shower head in no time.

How to Troubleshoot Common Issues with Shower Columns

Shower columns are convenient but can sometimes develop problems. Here are tips for diagnosing and fixing the most common issues.

Low Water Pressure

Poor water pressure can make showering a frustrating experience. Try these steps:

  • Remove showerhead and check for clogs
  • Check supply valves are fully open
  • Examine supply lines for blockages
  • Replace old galvanized supply pipes
  • Adjust pressure balance valve if present
  • Install booster pump if water pressure is very low


Leaking water can cause damage. Things to check:

  • Inspect connections for loose fittings
  • Look for cracks in supply pipes
  • Examine gaskets/washers in connections
  • Check for pinhole leaks in shower hose
  • Tighten fittings with an adjustable wrench
  • Replace worn gaskets, washers, or hoses

Noisy Pipes

Clanking or hammering noises can be annoying. Try:

  • Securing pipes to prevent vibration
  • Adjusting water pressure at the main to avoid surge
  • Insulating pipes to muffle noise

Inspecting connections, supply lines, and parts can help determine the cause of most shower column troubles. Make gradual fixes and test to isolate the issue.
