Are the handles compatible?

Can I Change My Moen Roman Tub Trim?

This guide will help determine if your current Moen Roman Tub valve will be compatible with our newer trim styles. When replacing Roman Tub trim there are two areas you need to consider. Is the spout compatible? Are the handles compatible? Below will be instructions on how to determine each.

Step One-Will the Spout Fit?

Always turn your water supplies off before disassembling your faucet. With the supplies turned off, move your faucet’s handle to the “on” position to relieve pressure. 

 

If your fixture looks like either model below and the spout reach is less than 8", you have a Garden Tub. It is not compatible and will not connect to our new Moen Roman Tub trim styles.

How to Remove the Spout on Valves Prior to 2008

Note: If your Roman Tub has a handshower, it will include a spout with a built-in diverter valve. The spout will be compatibleTo determine if the handles will be compatible, see Will My Handles Fit.

1. Remove the round plug button from behind the spout.

2. Use a 5/32" Hex wrench to remove the Hex screw from behind the spout.

3. Pull up on the spout to remove the old spout. This may be difficult to remove due to sealant or putty around it. Do not try and rotate the spout when removing it as this can cause damage to the internal parts of the spout.

4. Measure the spout shank. This measurement should be taken from the base of the deck to the top of the spout shank. Some of our newer spouts require longer spout   shanks that older models.

 If the spout shank measures between 1 ⅜” to 1 ½”-Certain spouts will be compatible depending on the height of the spout shank.

If the spout shank measures under 1 ⅜”- No new spouts will not be compatible. The entire valve would need to be replaced in order to use any new Moen Roman Tub trim.

How to Remove the Spout on Valves After 2008 to the Present

Note: If your Roman Tub has a handshower, it will include a spout with a built-in diverter valve. The spout will be compatibleTo determine if the handles will be compatible, see Will My Handles Fit.

1. Remove the round plug button from behind the spout.

2. Use a 5/32" Hex wrench to remove the Hex screw from behind the spout.

3. Pull up on the spout to remove the old spout. This may be difficult to remove due to sealant or putty around it. Do not try and rotate the spout when removing it as this  can cause damage to the internal parts of the spout.

4. Measure the spout shank. This measurement should be taken from the base of the deck to the top of the spout shank. Some of our newer spouts require longer spout  shanks than older models.

5. Non-diverting tub spouts may have a no-cut adjustable shank. To adjust from a minimum of 1-1/4" to a maximum of 1-3/4", a 3/8" 6" square driver or Moen part number 150313 is required. To determine is this is your spout type, shine a flashlight down into the shank. See image below to determine if your valve has an adjustable shank.

Adjustable Valve Numbers:

  • 4792
  • 4793
  • 4794
  • 9792
  • 9793

 If the spout shank measures between 1 ⅜” to 1 ½”- Certain spouts will be compatible depending on the height of the spout shank.

If the spout shank measures under 1 ⅜”- No new spouts will not be compatible. The entire valve would need to be replaced in order to use any new Moen Roman Tub trim.

Step Two-Will My Handles Fit?
Remove the Handle

To determine if the handle will be compatible, it will need to be removed and the handle mechanism examined.

Always turn your water supplies off before disassembling your faucet. With the supplies turned off, move your faucet’s handle to the “on” position to relieve pressure.

1. Remove the Handle

Moen handle removal varies by model. See the three different handle types below:

A. Handle Unthreads Off

B. Uses a Phillips Screw

clipboard_e131ff9429cbbe34edfff4b62a5c9eae6.png

*If you remove the handle cap and do not see the top of a Phillips screw head, the whole handle will unthread off. See Image A.

C. Uses a 3/32 Hex Wrench

2. Examine the Handle Mechanism (Stem Extension).

With the handle removed, what do you see?

Vertical Indents (Splines)

clipboard_eb6a4202c3627e18ebac7d9f89bf0ea2c.png

If the stem extension has vertical indents (splines), and the spout meets the height requirements, any of our new Roman Tub trim will be compatible. 

If the stem extension has 3 vertical indents (splines) on one side and 5 vertical indents (splines) on the opposite side and the spout meets the height requirements, any of our new Roman Tub trim will be compatible. 

"D" Profile with a Chrome Metal Nut

If there is a chrome hexagonal metal nut that holds the assembly together and the spout meets the height requirements, the valve can be modified to accept our new Roman Tub  trim. It will require the assembly pieces be removed and replaced with all the parts located in Moen Service Kit 106378. This kit includes both the hot and cold valves internal parts.

"D" Profile with a White Plastic Nut

If there is a white plastic hexagonal nut that hold the assembly together, then the threads on the inside of the valve body will need to be analyzed.  

 1. Make sure your water supplies are off.

 2. Unscrew this white plastic nut and remove the  stem extension/handle adapter.

 3. Inspect the interior of the valve body.

If the valve body is threaded all the way down the inside of the valve and the spout meets the height requirements, the valve can be modified to accept our new Roman Tub trim. It will require the assembly pieces be removed and replaced with all the parts located in Moen Service Kit 106378. This kit includes both the hot and cold valves internal parts.

If the valve body is not threaded all the way down, then the new handles cannot be used. The only option would be to replace the full valve body and trim.
