Tub Spout Height Limit: Know All About It In Details

Took the decision to have the perfect bath in your tub. But the water is falling right on your face. You don’t want that, right? 

This will occur if your tub spout is not rightly positioned. Placing a tub spout can be tricky since several aspects must be considered prior to placement.

But at what height a tub spout height is ideal?

The ideal is 4-16 inches above the bathtub level respectively to the high point and low. But there are many factors like location and types of faucets and bathtubs that influence the work. The local regulation codes can change a few details in setting up a tub spout. 

A little too much to grasp? Don’t be concerned! Since we have a detailed guide that explains every step of the procedure.

So, without further ado, let’s get right into the details!

How High Should Tub Spout Be Above Tub?

A spout should always be placed 4 in. above the bathtub on the sloppy side. 10 to 16 inches on the upper surface. Additionally, the faucet in a shower must be at least 45 inches from the floor. 

The nozzle should be placed somewhat higher, at least 70 to 76 inches above. If you still need to modify the position.

Then simply rough in the shower head at either a lower or higher location. As long as it satisfies the balance of your cosmetic and infrastructure design. For more aesthetics, you can also close the gap between tub and floor tile

Amongst the most challenging aspects are the diameter of the faucet and the tub. But both are changeable.

You should also examine the spout’s position with respect to the sidewall. Leaving ample space for the spout’s overhanging tub’s basin.

If the spout is too small or near, water will pour over the corners of the tub. And make a mess all over your floor.

Even if it sticks further out, it might be intrusive. Also, rub up against or poke you behind. All this leads to the spout’s maximum length over the bathtub.

It should not be too high also. Since this will cause the stream to splash forcefully. This might worsen with increased water flow.

Next, you can decide whether you want to place a spout for a bathtub. That just takes baths. Or even one that also takes showers.  Know how far the shower head can be from the wall. In case you install a shower as well. 

Lastly, confirm that the shower head, pressure regulator, and spout are all aligned. The very last issue you need is for them to be off, creating spillage.

How to Install Tub Spout: Step by Step Process

Now that you’re aware of the requirements, let’s get on to the installing stage. It is an easy and affordable task.

So, given the supplies listed below, you should have no trouble getting through the task.

Minimum Instruments and Supplies Required

  1. Screwdriver with four blades
  2. Caulking gun with adjustable gear
  3. Wrench for internal pipes
  4. Tube cutting machine
  5. Caulk made of silicone
  6. Spout
  7. Threading wire

Step 1: Unscrew the Old Faucets(If Any)

Using a spanner wrench, detach the old nozzle. Use an “internal” hose clamp if the nozzle is too small to hold with a wrench. It can cost you up to a dollar 7-10.

In case you are looking for recommended products, here are some:

Hope this helps with your task. 

Step 2: Set Up a Fresh Nip.

Curl threading tape around both sides of the replacement nipple. Then tighten it into the hole within the sidewall. 

Apply silicone sealant around it and clamp on the fresh spout.

Although toilet spouts can malfunction in 3 ways. Firstly, the tub spout converter might break out, allowing water to pass freely to the sprinkler. 

Secondly, when the spout clamps onto the pipes, the threads within the spout split or rust. Water can then drip down the tracks through the wall. 

Thirdly, the coating of the spout may peel or degrade.

The fresh spout should ideally fit neatly onto the old line. Yet, there is a strong possibility that the pipe extends down too far or little. There’s also the possibility that the joints are rusted.

In any case, you must eliminate the old pipe. Short threaded pipe pieces are called “nipples”. 

These are often offered in 1″ sizes. They’re less than $3 apiece in any market.  So get a few various sizes to save yourself more time. 

Step 3: Spout Varieties

Spouts that Slid-On:  Slip-on spouts are attached with a setscrew to 0.5 -inch Cu pipe. This generic version contains threading inside.  As well as allowing it to attach to the threaded pipe.

Spouts that Screw-On: Screw-on spouts feature substantial threads beneath. They may be connected to either copper screwed fittings or iron pipes.

Screw-on Spouts with Back-End Threads: Threads on the rear end of shaft spouts are possible. Most include a casing that allows them to fit 0.5-in. or 0.75-in. pipe.

These are the 3 most prevalent spout kinds. Even if you’ve placed your showerhead faucets and other bathtub fittings. Learn the full installation instructions for these spouts.

Choosing a Location for Tub Spout

You should already be aware of how critical the location is. Once you’ve determined the conventional tub spout height. The next step is to locate the placement of the tub filler. 

The design of the bathtub in your bath is a major consideration. Consider this as the ideal position for your bathtub spout.

Freestanding Tub

It is essential for a standing tub, that spouts extend up to the inside. The spout should aim straight inside the bathtub. So that any water that comes out goes within the tub.

You should also make sure the faucet control is conveniently reachable. When having a bath within the tube, the controls should be easily accessible.

You should also be able to reach the controls without having to enter the tub. So the location is to be well calculated before fittings.

Standing tubs come in a variety of forms.

If you’re using a slipper tub i.e a tub having one lower and one higher end. It’s better to put the spout on the sloppy part.

If the lower portion is in the center, place the outlet in the center, near the wall. This makes it much easier to use the controls and makes the bathing more enjoyable.

Enclosed Tub

An enclosed tub differs from a freestanding tub. It is surrounded by walls. For best results, place the spout at the midpoint of either the first or last end.

It is best to line the knobs and the nozzle for aesthetic reasons. Anyways if any damage was done in the process. For that know time needed to retile a bathroom in advance. 

What Determines the Distance Between Shower Fittings?

Everything has some set of rules and regulations. Same for the matter of spout positioning. ADA (Americans with Disabilities Act) works strictly for such matters. 

Plumbing Local Codes

These vary from one authority to another. Certain locations, for example, demand the showerhead to be 70 inches tall.

Others want it to be 75 ” from the bathtub pan. Some rules are more permissive, enabling varied heights and spacing amongst bathroom accessories.

Individual Interests

Aside from plumbing standards, your circumstance might influence how much room you leave around fittings. 

For instance, regional rules require the showerhead to be placed at 70 ′′. Someone else in the family stands taller than 72 inches. The height may then be adjusted to fit the tallest member.

Take into account regulations while making changes to your pipework. Guarantee that you follow them at all times. 


What will the height of shower taps be?

If the shower isn’t connected to a bathtub. Then you may raise the controls to 36 to 46 inches off the floor. This places them at a suitable scale for the average height person. While installing the keys, have a friend hold them at an approximated height. Verify if they are appropriate.

How far should the tub spout extend?

The tub spout should protrude from the finished wall from 3/8″- 3/4″. Although different geographical locations have different aspects to it. 

How significant is the length of the tub spout?

The length of the tub spout is significant. Although tub spouts exist in a variety of diameters. There is no one size fits all size for a tub spout. Because spouts vary in size and piping beneath the wall is placed at varying depths.


That will be all on our guide on tub spout height. Hopefully, you found this guide interesting.
