Shower Valve too Deep in Wall

The faucet or other item at the end of your shower is called a shower valve. When you turn it on, the showerhead, mounted on a safe moving arm, begins spraying water.

Because the shower valve is concealed behind a tiled wall, it is recessed too deeply. By cutting a more accessible hole in the drywall, you may remove the shower valve from the wall and start anew. Install a new shower valve after that so you can easily reach it for cleaning.

The second option is to remove the shower valve and replace it with a new, flush-mounted one.

To begin with, make sure your hand can fit through it. Then, after removing the two screws holding it in place, screw it back into the wall.

This technique works great for those with hardwood floors and tiles on their walls.

Tile shower walls

This technique will not work on hardwood floors, but it will be effective if your shower is typically 5″ x 6″ in size and your flooring is 1/2″ thick.

The floor and shower wall must first be leveled using a level before you can proceed.

You must unscrew the tile around the shower wall to provide enough room to reach the screws from behind. All you need to remove these screws is a drill that is attached to the masonry.

If the bathroom flooring is ceramic tile, which is more flexible than hardwood, many people will utilize this technique.

How A Shower Valve too Deep In The Wall?

The maximum and minimum distance from the finished wall surface are 2-3/16″ (56 mm) and 1-7/16″ (37 mm), respectively. Of course, the plumbing codes in your location may change this, but this is an excellent general guideline.

Additionally, bathroom faucets must satisfy the same installation depth requirements. Depending on the sort of shower you have, this depth;

In most modern installations, the shower pan must be 22″ (559 mm) in width, with the wall-mounted showerhead having a minimum clearance of 10″ (254 mm) and a maximum clearance of 18″ (457 mm) for all shower types.

The installation procedure will be easier if you buy a recessed shower valve since you may purchase a smaller shower pan.

Most wall-mounted (casing-type) valves need 1″ (25mm) of faceplate travel for every inch.

To satisfy the exact minimum wall surface clearance requirement, you may alternatively utilize an adjustable shower head.

The maximum water flow you want to utilize will also influence the size of the showerhead.

Your maximum water flow will be 5 gallons per minute if you use an average 7/8-inch-size shower head, which most people use and has a faceplate travel of 1″ (25mm) (GPM).

The smallest 10 GPM is still overkill for most homes, but it’s an improvement over nothing and can fulfill the average family’s needs.

The biggest shower head size is 2″ (51mm), with a larger water face but the same GPM.

A 1-1/2 (38mm) shower head minimum for a small family is ideal since it allows 1.5 GPM water flow.

How Do You Adjust A Mixing Valve Depth?

First, you should pull the handle over your lawn or garden.

When you do this, you have opened a hole and permitted more water to flow out, increasing the water pressure on that outlet over normal.

To compare the two, you may open another outlet simultaneously. Mark which of these two outlets has a deeper setting so you remember later when comparing them.

You should first concentrate on the easier of the two handles.

Next, pull down on the handle; this should be sufficient to open that one outlet. You could notice that it extends long enough to pour water into it if you want to.

I advise turning on a mixing valve only if you are certain of its depth.

You should not provide excess water pressure to a water outlet that needs less water pressure than you can provide.

Let’s now move on to the second handle, which is a lot trickier to use. Again, you’ll need help since altering the valve depth may be difficult.

Turn the handle all the way down before opening your mixing valve and trying to change the depth of your valve. It’s a good idea to do this.

Remember that this valve was likely at its deepest position when you initially purchased your mixer.

A blade spins when you raise and lower the other handle on specific mixers. In this manner, the water flow will be reduced until you are ready for it to resume.

If your mixer lacks this kind of valve, you will need to manually change the valve depth by turning the handle down gently each time you want the water to flow more slowly or less slowly.

You are prepared to change the valve depth after you have lowered the handle. On top of the mixing valve is where you will change your valve depth.

You’ll see an arrow-marked line pointing toward the valve’s rear on one side of the valve.

The cylinder that makes up this portion of your mixing valve has holes bored into it at various depths.

Slowly turn the cylinder clockwise or counterclockwise as you locate the ideal setting for your yard’s requirements.

If your water needs to flow slower, the pitcher and the water supply need to have a slope that forces you to crank the cylinder down an additional fraction of a turn for every inch.

How Do You Adjust A Shower Valve body?

It’s a very easy process to adjust your shower valve if you need to. To start, remove the handle and the screw keeping the faucet’s top in place.

Before replacing the handle and securing it, tighten or loosen the screw to adjust the water flow as desired.

After you finish, you may turn on the water to test the shower’s pressure and temperature.

Step 1: Remove The Handle Or Knob

Your shower faucet’s handle is held in place by a screw you must remove. Use an adjustable wrench to loosen the knurled shower faucet until it comes off gradually.

Remove the handle of a screwless shower faucet with care using your hands. Then, use a straight paperclip or toothpick to remove any little pieces of soap that are still attached.

Step 2: Adjust Your Shower Control Valve

Move the lever up or down to alter the warm water from your shower if you have to adjust the control valve.

Before turning on the water again, replace the handle and secure it with a screwdriver or adjustable wrench.

Step 3: Test Your Shower

By turning on the water and adjusting the hot and cold knobs, make sure the water is at the right temperature and pressure for you.

If your home is older, it’s crucial to use plumbing pipe tape and other leak-proof sealants to tighten all the pipes.

Only overtighten something since you risk breaking it and causing leaks.

What Do You Do If Your Shower Valve Sticks Out Too Far?

The valve knobs are too close together for the shut-off valves to function correctly, which is the basis of the issue. Here are several solutions to this issue.

Remove the outdated shut-off valve knobs first. The valve should sit at a 45-degree angle and be about flush with the front of the valve.

To get it near enough, if it’s too high, you’ll need to bring it down with a screwdriver or other pointed item. Then, while the old knobs are still off, take photographs of them.

To utilize them without creating a brand-new hole in the wall, you’ll need a new pair of bronze handles that are just a little longer.

The next step is to remove the shut-off valves by following these directions.

You must shut off the water main supply, unplumb, mark the location on your pipes, and remove both valves from their respective positions before you may remove them.

After removing the valves, you should take them to your neighborhood plumbing supply shop and purchase a new pair of bronze handles.

The handles should be positioned such that they are at a 45-degree angle with the shower valve.

To allow water to pass through the valve without having it protrude too much while in use, I advise doing.

Take the old shut-off valves back to your home after you have the new handles and install them there.

Ensure that one of the valves is flush with the shower wall and that both are positioned at a 45-degree angle. This helps provide you with more space for water flow and is done for aesthetic purposes.

The last step is to return behind your pipes, look for leaks, switch on your main water supply, and verify that everything functions as it should.

If it doesn’t, don’t go behind the wall or re-plumb. Instead, speak with a plumber to assist you with the issue.

For this job, the shut-off valves will need to be modified.

If you don’t want to remove your current shut-off valves, buying a few shut-off valves and replacement parts handles is the best option.


Showerheads and valves should not be taken lightly. This may be a costly error and result in significant water damage to your home if installed incorrectly.


The size of the showerhead and the actual state of your showerhead and faucet must be considered for proper installation.
