Some Information about Plumbing and Plumbing tools
A bathtub (in the UK simply bath) is a plumbing fixture used for bathing. Most modern bathtubs are made of acrylic or fibreglass, but alternatives are available in the form of porcelain-coated steel or increasingly wood. Older western bathtubs are usually made of galvanized steel or iron. Traditional Japanese bathtubs were usually of a wooden construction.
