Shower Valve Too Deep In The Wall

A shower valve is a faucet or fixture at the end of your shower. When you turn it on, water comes from the shower-head attached to a secure moveable arm.

Your shower valve is too deep in a wall because the shower valve is behind a tiled wall. You can unscrew the shower valve from the wall and start over by going through the drywall in a more accessible location. Then, install a new shower valve so that you have easy access when it comes time to clean it.

The second option is to remove the shower valve and install a new one flush with the wall.

First, ensure it’s wide enough for your hand to fit through. Then you need to loosen the two screws holding it, then unscrew it from the wall.

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

Tile shower walls

You should note that this technique is unsuitable for hardwood floors, but if your shower is a standard 5” x 6” in size and your flooring is 1/2” thick, this will work fine.

First, you must use a level to level out the floor and the shower wall before beginning.

To access the shower wall, you unscrew the tile from around it to have enough space to unscrew the screws from behind. All you need is to get these screws out is a drill attached to masonry.

Many people will use this method if they have ceramic tile as their bathroom flooring because ceramic has more flexibility than hardwood.

How Deep Is A Shower Valve In The Wall?

The maximum is 2-3/16” (56 mm), and the minimum is 1-7/16” (37 mm) from the finished wall surface. This can vary depending on your local plumbing codes, but this is a good rule.

Also, this installation depth requirement is the same for lavatory faucets. This depth will depend on your type of shower;

Most modern installations require 22” (559 mm) in the shower pan, with a minimum of 10” (254 mm) for the wall-mounted shower-head and a maximum of 18” (457 mm) for all shower types.

When you choose to go with a recessed shower valve, you can get a smaller shower pan, which will make the installation process more manageable.

Most wall-mounted (casing-type) valves will require 1” (25mm) per inch of faceplate travel.

You can also use an adjustable shower head with the exact minimum wall surface clearance requirement.

The showerhead size also depends on the maximum water flow you plan to use.

If you’re going with a standard 7/8-inch-size shower head like most people, which has 1” (25mm) of faceplate travel, then your maximum water flow will be 5 gallons per minute (GPM).

The smallest 10 GPM is still overkilled for most homes, but it’s better than nothing and can supply the average family with all their needs.

The maximum shower head size is 2” (51mm), giving the same GPM but a larger water face.

The minimum shower head size is 1-1/2 (38mm), which will allow 1.5 GPM of water flow, and it’s perfect for a small family.

How Do You Adjust A Mixing Valve Depth?

First, You will want to pull the handle to the top of your lawn or garden.

When you do this, the water pressure on that outlet is higher than usual because you have opened up a hole and allowed more water to flow out.

You may want to open one other outlet simultaneously to compare the two. When comparing these two outlets, mark which one has a deeper setting if you forget later.

For now, you will want to concentrate on the easier of the two handles.

Next, Pull down on the handle, which will probably be enough to open up that one outlet. You may see that it opens up far enough so that you could pour water into it if you were so inclined.

I recommend not running water into a mixing valve until you know how deep it is.

You do not want to create too much water pressure on an outlet that requires less water pressure than you can provide.

Now let’s move on to the other handle, which is much more challenging to operate. You will probably want someone else’s help with this one since it easily gets confused while adjusting the valve depth.

Before you open up your mixing valve and try to adjust your valve depth, turn the handle down so it’s as low as it can go. This is an excellent thing to do.

Remember that this valve is probably at its maximum depth when you first bought your mixer.

Some mixers have a blade that rotates when you move the other handle up and down. That way, it will decrease water flow until you are ready for it to start flowing again.

If your mixer does not have this type of valve, you will have to adjust your valve depth manually by slowly turning the handle down each time you want your water to flow less or more slowly.

Once you have pulled the handle down, you are ready to adjust your valve depth. The place where you will adjust your valve depth is on top of the mixing valve.

On one side of the valve, you will see a line marked with an arrow directing you toward the back of the valve.

This part of your mixing valve is a cylinder with a hole drilled into it at different depths.

Slowly rotate this cylinder clockwise or counterclockwise until you find the right setting for your yard’s needs.

The pitcher and the water source have to have a slope that requires you to turn the cylinder down a little more for every inch you need your water to flow slower if your water has to flow slower.

How Do You Adjust A Shower Valve?

If you need to adjust your shower valve, it’s a pretty simple process. First, take off the handle and unscrew the screw on top of the faucet that holds it in place.

Next, tighten or loosen the screw to adjust your water flow as desired before replacing the handle and tightening it down securely.

Once you finish, you can turn on the water to check the pressure and temperature of your shower.

Step 1: Remove The Handle Or Knob

Undo the screw on top of your shower faucet that holds the handle. If it’s a knurled shower faucet, use an adjustable wrench to loosen it until it comes off completely.

If it’s a screwless shower faucet, gently remove the handle by hand. Remove any small pieces of soap attached to it by lifting them off with a straightened paperclip or toothpick.

Step 2: Adjust Your Shower Control Valve

If you have to adjust your shower control valve, move the lever up or down to change how much hot water comes out of your shower.

Then replace the handle in its place and secure it with a screwdriver or adjustable wrench before turning on the water again.

Step 3: Test Your Shower

Make sure your water temperature and pressure are to your liking by turning on the water and adjusting the hot and cold knobs.

If you boast an older home, it’s important to tighten all the pipes using plumbing pipe tape and other types of sealants that prevent leaking.

Remember to be careful not to over-tighten anything, as you can break it and cause leaks.

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

The root of the problem is that the valve knobs are too close together for the shut-off valves to work properly. Here are ways of solving this problem

First, remove the old shut-off valve knobs. The valve should be about flush with the front of the valve and sit at about a 45-degree angle.

If it’s too high, you’ll need to try taking it down with a screwdriver or similar pointed object to get it close enough. Take pictures of the old knobs while they’re still off.

You’re going to desire a new set of bronze handles that are slightly longer so that you can use them without having to make a whole new hole in the wall.

The second thing to do is follow these instructions and remove the shut-off valves.

To take them out, you’ll need to turn off the water main supply, un-plumb, mark the location on your pipes, and remove both valves from their respective locations.

Once you remove the valves, you’ll want to take the valves over to your local Plumbing supply store and buy a new set of bronze handles.

You want the handles to sit at about a 45-degree angle with your shower valve.

I recommend this because it gives you enough room for water to flow through the valve without having it stick out too far when in use.

Once you have the new handles, take the old shut-off valves back to your house and put in the new handles.

You’ll want to make sure that both valves are at a 45-degree angle and that one of them is flush with your shower wall. This is for aesthetic reasons and helps give you more room for water flow.

The last thing to do is go back behind your pipes, check for leaks, turn on your main water supply, and see if everything works properly.

Do not go behind the wall or re-plumb if it doesn’t. Instead, contact a plumber to help you with the problem.

Note: You’ll need to modify the shut-off valves for this project.

Purchasing a few shut-off valves and spare parts handles is most suitable if you don’t want to disassemble your existing shut-off valves.

Do Shower Valves Have Flow Restrictors?

Yes. Shower and tub valves have flow restrictors that help reduce water consumption.

I call the portion of the shower valve containing this restrictor a conservation outlet, and you will find it in the tub or shower diverter arm.

For example, if you have a fixed tub spout, it contains no restrictor and will deliver water to the tub at full capacity to help reduce your water use.

If you have a diverter with a movable arm controlled by the valve, you can adjust it to how much water reaches the tub or shower.

However, not all tub or shower valves have flow restrictors, so be aware when choosing which type of valve you would like for your installation.

If you are replacing an existing shower valve, you can find the flow restrictor inside the mounting flange of your existing valve.

For a new shower or tub valve, the restrictor is often preloaded into the arm of your new valve.

However, if you find a restriction missing from your new control, you can install it to correct this oversight by following these simple steps:

  1. Unscrew and remove the arm on which the flow restrictor is.
  2. Using a screwdriver, carefully place the restrictor into the arm where the hot and cold water lines are.
  3. Reassemble the control arm, ensuring you have properly positioned it to provide even control of water flow at each setting.
  4. Test your new shower or tub flow restrictor by operating your valve at various settings to ensure that water delivery will be adequate and consistent in every setting.

If you are replacing a removed flow restrictor, ensure that you set the flow restrictor to a slower delivery by unscrewing it and twisting it until you reach the desired setting.

Remember to regularly check your new shower or tub valve settings and adjust them if necessary.

For example, if you have plenty of water running at a slower setting than you would like, remove the faucet faceplate and turn the restrictor counterclockwise with your hand until it reaches the desired setting.

How Do You Adjust A Kohler Shower Mixing Valve?

Adjusting a Kohler shower mixing valve is simple, with only five easy steps.

Step 1: Switch the water supply to the mixing valve at the main shut-off valve.

Step 2: Remove the old washer from the mixing valve.

Step 3: Lubricate one side of a new washer with petroleum jelly or Teflon tape, according to your manufacturer’s instructions. This helps ensure a good seal and prevents any leaks.

Step 4: Carefully place the washer in the valve. Please don’t drop it.

Step 5: Adjust the mixing valve to a comfortable temperature and enjoy your new, warm shower.

After making these adjustments, you may leak somewhere in your plumbing system if water still drips from the showerhead.

Call a licensed plumber to fix them if you need help locating any leaks or fixing your plumbing issues.

Are Anti-Scald Valves Required?

Yes. In residential buildings, you must equip all dishwashers and sinks with an anti-scald valve. This is a crucial safety measure to prevent burns from hot water.

Anti-scald valves are not just for the comfort of your tenants and occupants but also their protection.

With a thermostatic mixing valve, you can easily control the water temperature of your faucet and change it to be more comfortable or practical for specific tasks.

In this case, you cannot increase the water temperature to a high level without causing injury to those who use your dishwasher. Anti-scald valves prevent those accidents.

The most important part of an anti-scald valve is that it is thermostatic, so it will not open at temperatures that exceed a certain point.

All thermostatic mixing valves should have anti-scald parts to work efficiently and effectively at moderate temperatures.

Most anti-scald valves will open at around 160 degrees, but the acceptable temperature range for anti-scald devices is 140 to 180 degrees.

Anti-scald valves also come with a temperature limiter, which prevents the thermometer from going too high and causing injury.

This feature is only available for mixing thermostatic mixing valves and not on thermostatic mixing shut-off valves.

Over time, you may notice your anti-scald valve malfunctioning or not working properly. If your shut-off valve is not working correctly, it could cause scalding.

Are Shower Valves The Same As Cartridges?

Yes. They are the same. A shower valve controls water flow in a shower. It can come in two forms: a ceramic ball or a cartridge.

Because of its shape, a shower’s valve can get clogged with minerals and other debris.

Stop this by installing an anti-lime cartridge every five years, depending on how often you take showers and whether you use soap or shampoo.

A plumber can easily replace a shower cartridge, like replacing an old one with a new one.

It’s suitable that you change your cartridges every five years because if you don’t, it could lead to significant problems for your plumbing system.

Also, if you have never replaced your cartridge yet, you must do so before installing a showerhead or changing its location.

This way, you will prevent problems from occurring because of debris clogging up your valve.

However, this is not true for shower valves with certain styles. Luckily, you can replace it with no problem at all.

You can do this because the existing shower valve is just like a cartridge, and replacing it with one like the new one is easy.

Continue using your existing shower valve until the time comes to replace it if you have never returned your cartridge before and know how to do so without getting help from a professional plumber.

Another benefit of shower valves is that they are not expensive and are easy to replace.

Before buying a new cartridge, check the manufacturer’s website or the package to find the proper measurements.

If you have an old cartridge, measure it using a ruler and compare your measurements to those provided.

Can You Adjust The Shower Scald Guard?

Yes. The shower curtain prevents water from shooting out. You can adjust it to spray the water differently by turning it.

When you turn the showering head, change it to direct the water flow and spray near your feet for better pressure. You can also switch to a pulsating stream if you choose this option.

There are two types of showers, stationary and handheld. You can adjust the handheld type by bending it in any direction to direct water spray.

If you want to soften your shower, adjust it so that the spray hits you at a lower angle of about 30 degrees. This will force the water to spread and soften when it touches you.

Any temperature changes will also require adjusting the showerhead. Turn it away or toward your body to increase or decrease the temperature.

For instance, if you’re in a cold shower and unsatisfied with the temperature, turn the showerhead away.

Shower Valve Too Deep In The Wall

Besides adjusting the water flow, there are other ways to improve your showering experience. This is the reason most men prefer the handheld type of showers.

The first tip is about using less water before taking a hot shower. If you want to save water, you should undress while in the shower and keep the water flowing.

It’s possible that if you want to take a hot shower, then remove the showerhead from its place and keep it in your hand.

This will cause less splashing, which will help prevent wasting water.

Before starting your hot shower, ensure all the faucets are off so they won’t waste any more water. You can also turn off the showerhead so you won’t get more water.

The next tip is about how to adjust the temperature of the water. If you have a large body area to wash, then use a hot shower and turn it away from your body. 

You should also learn to use less hot water before a cold shower. If you have a small body area to wash, take cold showers and switch back to warm ones afterwards.

Another tip is about how to take a refreshing shower. Since we’re already in the cold shower, you should know that you should get into a cold shower after exercise.

Do I Need A Thermostatic Valve For A Shower?

Yes. Your shower needs a thermostatic valve to control the temperature in your shower. This will make sure your water is at a constant and safe temperature.

Thermostatic valves are easy to install, so it doesn’t take much time.

Some people enjoy this task because they get to work with their hands, and it feels more personal than installing a new gadget in the household.

Depending on what you already have in your bathroom, you can install the thermostatic valve for under $100, which is much better than the average shower installation costs.

After all, you get to spend a little quality time with your partner and save some money simultaneously.

So, if your shower is not steaming up, and the temperature has to be at a constant 50°F at all times because of mold or other reasons, install a thermostatic valve.

This will make you feel clean and fresh every time you shower.

What Is A Shower Valve Cartridge?

A shower valve is one of four valves that you’ll find inside a faucet. The valve is critical in the operation of shower or bathtub water, and it’s a part that you should replace if it’s not working properly.

A shower valve cartridge stays attached to the faucet handle and has a set of rubber seals that help regulate water. This cartridge replaces the faucet handle when necessary.

If you notice any leaks around your shower head or any other defects with your water quality, it’s best to replace your valve cartridge right away so you have peace of mind on these matters.

Shower valve cartridges are durable, and you can often use them for years.

Replacing it regularly will help prevent the wear and tear caused by hard water, which gradually erodes your valve.

It’s recommended that you replace your shower valve cartridge every two to three years, depending on how often you run your shower head or bathtub water.

You can easily replace shower valve cartridges, which is typically a fairly straightforward process.

Before you do that, it’s best to confer with a professional plumber or local home appliance expert to figure out if this is something you can handle on your own.

Too many people try repairing or changing shower valves on their own, resulting in costly repairs that you should have avoided with assistance from a professional.

Are Shower Valves Adjustable?

Yes. Shower valves are adjustable based on the height of the user. Most shower valves have a lever and a knob near the handle that change how high or low water flows out of the showerhead.

If unsure, check your valve’s manual to see if it’s adjustable.

Some shower valves have an extra lever beside the handle and knob that adjusts cold/hot water settings.

The turn valve also controls whether you receive air from your warm air hand drying system when said system activates.

You can adjust the hot and cold water temperature if your shower valve has a dial. Shower valves often have a showerhead, hand shower, and rain shower head.

Sometimes the dial adjusts the rain head, and sometimes, it isn’t. Shower valves may also be adjustable based on their durability and ease of access.

For example, a 5-inch valve is for those short and requires little stretching to clean themselves in the shower or rinse off after stepping out of the bathtub.

In such a case, you can adjust the valve easily while standing.

A 5-inch valve is also ideal for people who aren’t tall and looking for a compact shower fixture that doesn’t take up too much space.

This is important if you do not have enough space in their bathroom or those who wish to have more storage space in their bathroom.

While 5-inch valves may not allow you to reach all parts of your body, especially your back, at least you can cleanse the essential areas of your body with ease and comfort.

The same is true for shower heads with smaller diameters, such as five or 6-inch showers.

You can also adjust shower valves based on their installations. For example, you can adjust a shower valve higher or lower to accommodate the user’s height in the shower.

A taller person may wish to adjust the water flow up and down, while a shorter person may prefer that they have more control over the water flow from the showerhead.

Can Showerheads Use Exterior Walls?

No. Water can drip onto the floor if you construct a shower with an exterior wall. You should not set up drip-proof showerheads outside the walls.

If you are installing a new showerhead, it’s best to have it mounted on an interior wall and use a separate pipe for the water supply.

An unusual installation situation is when you have a tub in one corner of your bathroom and want to install the showerhead at an angle out of view from the vanity/countertop in that area.

You may do this installation if you want to have the shower pan covered with a thin waterproof membrane layer for the flooring.

If you already have the exterior wall, you can have a drip-proof shower head, but use an extra waterproof layer of caulk to prevent water from leaking on the floor.

If your shower has an exterior wall and you still want to use a drip-proof shower head outside the wall, ensure you use plenty of caulks and waterproof membrane for the flooring above it.


You should not take showerheads and valves lightly. If it’s not installed properly, this can be a costly mistake and cause severe water damage in your home.

For proper installation, you need to note the size of the showerhead and the actual condition of your shower head and faucet.
