The Tub Water Supply Shower Planar Cross Shutoff Valves Diverter Pipe Drain Rim Flexible Connector The Tub 0 The Tub 1 The Tub 2 The Tub 3 The Tub 4 The Tub 5 The Tub 6 Your bathtub has a surprising number of components, as you might expect. All the components—plumbing, drainage, and the tub itself—must function in unison.

A general grasp of your bathtub is beneficial for homeowners, especially if you intend to perform any DIY repair.

The key element is the tub itself, which is probably what comes to mind first. It might have an oval or rectangular shape.
Even some more luxurious bathtubs are circular.
While you bathe, the tub stores the water. It has taps to allow water to enter and a drainage system to allow water to exit.
To fill the container with water, you can block the main drain; alternatively, if you’re taking a shower, you can let the water drain continuously.
Some modern tub designs come with thermostat valves that let you precisely regulate the water’s temperature. This prevents you from possibly getting burned.
However, as long as you use the faucets cautiously, you generally don’t have to worry about burns.


Usually, your central plumbing instead than the bathtub itself will supply the water. Cold and hot water will flow through the pipes when you switch on the faucets.

Depending on where you live, water may come from a city system or an underground well. It’s crucial to frequently test the water for damage and pollutants.

The water heater in your home or apartment usually provides warm water. A condenser or tower circulates cold water through it.
As a homeowner, it’s useful to know where your water comes from, but you probably won’t need to mess with it.

An essential part of the bathtub is the showerhead or spout, which is connected to the piping that regulates your water supply. There are many different sizes and shapes for showerheads.

Others are fixed into the wall, while some are detachable.
The size of the showerhead will affect how much water flows. Efficiency models frequently feature lower flows in order to save water.
Even the majority of showerheads come with parts that automatically limit the flow of water.
Control valves are used in showers to combine hot and cold water. This makes it possible to create the ideal blend for a cozy temperature.
You should use caution while working with an older device that lacks precise controls to prevent inadvertent self-burning.
Plane Crossing A type of linked piping used to regulate water flow is called a planar cross. Typically, you won’t find it anywhere besides baths.
The phrase “planar cross” is derived from geometry and refers to the intersection of two distinct planes via a solid object.

Shutoff valves are employed to regulate the water flow via your piping. Principal and fixture valves are the two primary types of valves.

As the name suggests, a fixture valve is one that is attached to a fixture in the home. Each is intended to be placed using a certain stop valve.

These let you to stop the water flow to a broken appliance without having to shut off your entire water supply.

Having said that, fixture valves have only just started to become commonplace. If you’re working with older equipment, the plumbing may not have a specific shutoff valve built in.

When this is the case, you must turn off your complete central water system before starting any repairs. For this reason, replacing outdated plumbing fixtures with newer models is a good idea.


The diverter pipe aids in moving the water flow to a central location or away from a specific area. Its function is to regulate the direction of the water’s flow.

A diverter pipe is probably to blame for how warm and cold water stream out of the same faucet in your tub. The diverter design directs both water flows into a single central pipe after initially traveling to the tub in separate pipes.

You can then obtain a mixture that is at the ideal temperature.

Diverter pipes are also seen in other appliances like sinks and outdoor faucets, in addition to bathtubs. A worn-out diverter pipe that needs to be replaced frequently contributes to unexpectedly low water pressure.


Maintaining your bathtub drain can occasionally be difficult, especially if it becomes clogged. But when you’re done bathing, the drainage mechanism is what makes it simple for you to remove the water from the tub.

Hair and soap scum are a couple of the factors that can cause a blocked tub drain. If there is no trap to prevent hair and grime from building up in the pipes, your drain is more likely to become stopped.


The top of the bathtub is referred to as the rim. It establishes a solid foundation to keep the tub in place.
Many individuals keep their soap, shampoo, and other accessories on the rim’s surface.

The rim’s ability to catch water when the tub is about to overflow is another crucial feature. Despite the fact that it won’t stop a genuine overflow problem, it will stop water from leaking down the sides when the tub is completely filled.

That is crucial to maintaining the floor of your bathroom.
VERSATILE CONNECTOR Plumbing tools of the sort known as flexible connectors are frequently utilized in bathtub installations. Depending on your demands, there are several sorts.
One of these connectors’ primary functions is to join two pipes that can’t otherwise be joined.
Most flexible connectors are made of braided steel. They can be extended through spaces that a straight pipe cannot because of their flexible construction.
They can also be used with almost any house’s plumbing system.
One of these gadgets is probably the best choice if your bathtub plumbing requires additional connections.

There is an overflow pipe in every tub. Between the connectors and the drain lies this pipe.

The overflow drain starts siphoning water out of the tub when the water level gets too high. As a result, the load is reduced and the water is diverted away from the drain.

When the water level reaches a specific level, overflow pipes begin to operate automatically. They are crucial for averting future mishaps.

Your tub is not sucked into or out of by the waste outlet. Its duty is to prevent garbage from entering.

The outlet stops waste from running back up the pipes by drawing it into the drain. This prevents a mix-up between your main water supply and used toilet and bath water.

Maintaining the cleanliness of your plumbing and water supply would be considerably more challenging without a waste outlet.

P TRAP P traps are a particular kind of plumbing that are frequently installed in sinks but may also be present in bathtubs. The drainage system is covered by this fixture.

It stops obstructions like soap and hair from slipping into drains and getting stuck far inside the system.

The other function of a P trap is to prevent sewer gas from entering your home through the pipes. These fixtures could be made of PVC piping or steel.

Although both materials are effective, steel is preferred for exposed areas because to its attractive appearance.
Depending on your state’s or country’s building rules, the precise configuration of a P trap may change.



In your bathroom, the internal plumbing is hidden by decorative paneling. Typically, tiles or stones are used to construct it.
The pipes that are incorporated into the walls and floors will be hidden by this paneling.

For the walls surrounding the tub, certain bathtubs may come with their own ornate paneling. Depending on how obtrusive the design is compared to the standard wall fixings

LINING The area of the wall that the bathtub is attached to is called the bathtub lining. The wall lining is often present on at least two sides of bathtubs, and in some cases all three.

It is intended for bathtubs to drain into the plumbing system. A malfunction, on the other hand, could result in draining into the lining, which could create major difficulties and water damage.

The controls you use to fill the bathtub are faucets. You may turn them to alter the water’s force and temperature.
The actual faucets are constructed from a variety of parts. These give them the most effective system for controlling and occasionally purifying the water.

CONCLUSION There are numerous components in your bathtub, all of which work together to make it fill and drain efficiently. You’ll find dealing with basic home maintenance much easier if you comprehend how the plumbing and construction work.
