Replacing Shower Trim Without Replacing Valve

Replacing your existing shower valve trim with a new one is an easy and inexpensive way to renovate the bathroom.

If the trim in your shower is corroded or simply old-fashioned, you may want to replace it with a new one.

The good news is that you can do it yourself without hiring a plumber.

The first thing to do is determine your shower valve type. Look for any signs of the brand or manufacturer. If there is nothing there, you can try taking a photo of it and performing a quick Google image search. The chances are that you will find your shower valve trim, no matter how outdated it is.

Then you need to find a suitable replacement trim kit. Make sure to buy one with mounting holes in the same places as the existing one. Some have holes at 5:00 and 7:00 positions, and others have mounting holes at 2:00 and 7:00 o’clock.

Most kit packs will have a list of compatible valves.

Installation Instructions

Installing a new valve trim in the shower is quite straightforward, and with the proper tools and preparation, it should take up only a few minutes.

Here are the steps for the shower trim replacement

1. Remove the screws

First, use a suitable screwdriver to remove the screws which are holding the handle for the shower control. Then remove the handle or handles.

2. Place the new trim in place of the old one

If your new trim plate comes with an included gasket, you can go ahead and place it in place of the one you just removed. If not, you may need some caulk or plumber’s putty.

3. Screw the new trim plate

Once you place the new trim plate in the correct position, use the screwdriver to mount it by using the screws from your kit and the old holes.

4. If there is one, install the diverter

If your shower valve is compatible and your trim has it, install the diverter. This is the mechanism that will redirect the water from the pipes to the showerhead.

5. Install the retaining ring

After the diverter is installed, clip the retaining ring on. If it doesn’t click steadily in place, you may need to use adhesive caulk.

6. Install the stem cover for the valve

Follow the manufacturer’s directions to install the valve stem cover or covers.

7. Fasten the stem cover with an O-ring

Use the O-ring from your shower valve trim kit to fasten it.

8. Screw the control handle on

Screw the new control handle on the newly replaced shower trim, and you are done!
