John Shanks was a prime example of the Victorian ‘Self-made man’. Beginning his working life as a plumber, he pioneered what was to become the premier sanitary engineering firm in Britain. He was an astute businessman, a skilled inventor of many sanitary appliances and remained active until the last year of his life when ill-health finally forced him to retire Little is known about the early life of John Shanks. His father, William, was a Paisley handloom weaver and John was apprenticed as a plumber to Wallace and Connell of Glasgow. He worked as a journeyman plumber in the Paisley area until he was 30 years old when he transferred his business to the neighbouring town of Barrhead. While maintaining his plumbing business here, John Shanks began to devise and patent improvements to sanitary ware. He began with cheap portable bath rubs, finally devising fixed domestic appliances. He prided himself on his products being good quality, hard-wearing and of reasonable price. In 1875 he founded Shanks and Co, Sanitary Engineers, with his brother Andrew who had also been a plumber. The firm began on a small site in Main Street, Barrhead, employing eight people. With John as senior partner, the business expanded rapidly. Two decades later, the firm occupied a seven-acre site and employed 600 men, Barrhead’s single largest employer. It was John who was the innovator of the company, taking out some 100 patents by 1894.
All stages of the production of sanitary ware were completed on the Main Street site from iron-moulding to enamelling so that employees were engaged in 20 different trades. Shanks established his own pottery to ensure both uniformity of quality and economy in production. John Shanks always remembered his employees, providing in his will an extra day’s pay to employees who had been with the company for six months on the day of his death.
