How do bathtubs work?


It is possible to construct a bathtub either in an alcove with three walls or as a freestanding unit. Built-in tubs can range from conventional tub-and-shower combinations to cutting-edge, computerized whirlpool tubs that can automatically deliver and keep a set temperature of water constant. Freestanding tubs are also available in a wide variety of designs, ranging from the traditional claw-foot tub to sleek and sophisticated jetted models.

How do bathtubs function?

Even though there are a variety of bathtub types and designs on the market today, typically made of porcelain-enameled steel, thermoformed acrylic, or fiberglass-reinforced polyester, they all operate using the same water supply line and drain.

Bathtubs typically have three major components: the tub itself, the water supply line, and the drain. Valves are connected to hot and cold water supply lines, whereas drains are connected to a property’s drain line. In general, water exits faucets, remains in the bathtub, and exists through drains.

The following are some of the most prevalent varieties of bathtubs: clawfoot tubs, pedestal tubs, infant baths, hot tubs, whirlpool baths, freestanding bathtubs, and soft bathtubs.

All bathtubs are built to operate on the same concept, and in order for them to function effectively, they require water supply lines and a drain system. There are six typical varieties of bathtub drains, but their function is same.

However, there are numerous types of bathtubs, such as whirlpool and air tubs, that feature an internal pump that forces air through small holes to generate a bubble massage. These bathtub styles require energy to power the pumps.

Materials Commonly Used to Construct Bathtubs

How do bathtubs function

The finest bathtubs are constructed of enameled cast iron. Even though they are quite heavy, especially in larger sizes, cast-iron bathtubs have robust, rich finishes.

Because they are substantially lighter and more easily molded than cast-iron tubs, fiberglass-reinforced acrylic tubs are typically available in larger and more elaborate designs. Some bathtubs are also made of fiberglass, however these are susceptible to fading and scratching in direct sunlight.

The standard length of a bathtub is five feet, but baths can be as long as seven feet. Available in a variety of widths and depths. Shower-equipped bathtubs contain a diverter valve that shifts the water flow from the tub spout to the shower head. Here’s how the configuration works.

Two legs lead to the primary drain hole and the overflow drain opening on bathtub drains. Pop-up and plunger-type components are common for closing and opening the drain. Both are controlled by a trip lever located near the overflow drain.

Using a rocker arm, a linkage raises or lowers the drain stopper on a pop-up drain. With the plunger type, the drain aperture is sealed by a hollow brass plunger that glides up and down inside the drain assembly.

What if my bathtub is not functional?

If you find yourself in a position where your bathtub is not functioning, you must first determine the cause of the issue. Is the water supply operational? Does your bathtub have a leak, or is there an issue with the drain system? Once you have identified the issue, you should seek the assistance of a plumber.

What are the most frequent bathtub issues?

Bathtub frequent issues

Now that you understand how a bathtub operates, you should also be aware of the most common issues that can arise with any bathtub model. These issues may have been explained to you previously.

Tub Faucet Leak

If this issue is not addressed in a timely manner, you may be confronted with hefty water bills. This issue is simple to resolve, so you shouldn’t be too concerned. Due to the variety of pipe types in the bathroom, it might be difficult to pinpoint the exact source of a leak.

Reduced Water Pressure

This issue happens most frequently with shower heads. You can test this by running cold water through the pipe to see whether the pressure rises. This allows you to establish whether the blocked water flow is caused by the shower head or the pipes.

Sloping Drainage

If you have an issue with sluggish draining, the likely cause is clogged pipes. When we shave in the shower, our body hairs are eventually pulled into the drain and cause it to become clogged. Typically, this issue is resolved with several substances.

Damages to the Bathtub

Some bathtubs can develop cracks over time, which can lead to leaks. However, keep in mind that certain cracks can be so minute that they are invisible to the naked eye. Therefore, you must carefully inspect each component of the bathtub to pinpoint the location of the crack and stop the water from leaking.

How a bathtub drain functions?

Bathtub drain

It is possible to find bathtubs with two drains. The bathtub drain may be positioned at the tub’s base, at the drain hole, in the center, or at one end. The primary function of the bathtub drain is to expel water from the tub. Attached to the siphon, it offers a connection between the siphon and the bathtub.

It can be closed to convert the tub into a shower or a bath. Typically, the plug is closed by a shutter placed in the overflow and connected by cable to the plug.

It is possible, however, to prefer a foot-operated simple stopper or pop-up device. The drain and door contribute to the beauty of the bathtub.

The two most popular types of drain assemblies are plunger-type and pop-up. Simply inserting the plunger into the drain opening will seal the opening. The pop-up drain operates via a push mechanism. It ascends or descends when your feet are pressed against the floor. When the drain stopper is raised, water can enter the drain.

A Few Parting Thoughts

You should be aware that there are several varieties of bathtubs that come with additional features, such as whirlpool tubs and air tubs, despite the fact that every bathtub is created in the same way and operates according to the same basic concept. For the purpose of producing air bubbles, these tubs make use of a variety of pumps in conjunction with electric current.

Because you are now familiar with the fundamentals of how a bathtub operates, you will have no trouble recognizing and identifying any issues that may arise in the future. As a result, you will be able to determine whether you are capable of finding a solution to the problem on your own or whether you need to consult an expert.
