Bathtubs are available in many styles including classic claw-footed, sleek, jetted models, freestanding, modern computerized bathtubs etc. Most bathtubs are made from enameled cast iron. Other material used to make bathtubs include fiberglass-reinforced acrylic, fiberglass, and porcelain.
The conventional length of a bathtub is 5 feet but they can also be custom made in terms of material, length and depth depending on your requirement.
How Bathtubs Work
Freestanding bathtubs are most common. A freestanding bathtub installed in the corner of a bathroom creates a good illusion. How it works basically depends on its design and plumbing.
Bathtub drains have two legs, one to the main drain opening and the other to the overflow drain opening. Two different assemblies- pop-up and plunger-type are used to close and open the drain. These are operated by a trip lever.
Freestanding bathtub plumbing works the same as any regular bathtub plumbing. It has a drain in the front, joining to the drain pipe adjacent to the hot and cold water pipes that stop at the tub or it can even continue up for shower.
