Walk-in bathtubs have either an inward-opening or cap-like fitted door, descending to near ground level to allow a person to enter the tub without climbing over its side; the door is self-sealing. [1] Most walk-in bathtubs also have a chair-height seat, but some, which are the same basic configuration as a standard bathtub, do not have any seat.
Up-N-Away was the name of a vertical-sliding bath/shower door manufactured by Unitspan Architectural Systems, Inc. The bathtub shower doors had vertical tracks instead of horizontal, and closed downward or opened upwards rather than sideways. The channel tracks were vertical on each side with only a low profile sill necessary across the front ...
Documented early plumbing systems for bathing go back as far as around 3300 BC with the discovery of copper water pipes beneath a palace in ancient Europe. [citation needed] Evidence of the earliest surviving personal sized bath tub was found on the Isle of Crete where a 1.5-metre (5 ft) long pedestal tub was found built from hardened pottery. [1]
Designated as an American National Standard, the Uniform Swimming Pool, Spa and Hot Tub Code (USPSHTC) is a model code developed by the International Association of Plumbing and Mechanical Officials to govern the installation and inspection of plumbing systems associated with swimming pools, spas and hot tubs as a means of promoting the public's health, safety and welfare.
These terms are the terms typically used on floor plans for residences or other buildings. Real estate advertisements for residences often refer to "three-piece washrooms" (include a bathtub or shower) and "two-piece washrooms" (only toilet and sink). In public athletic or aquatic facilities, showers are available in locker rooms.
Bathtub liners also known as tub liners, acrylic tub liners and tub inserts are made by vacuum forming an acrylic or PVC (poly vinyl chloride) sheet which is heated then formed in a mold by applying vacuum. Having the proper mold is important for the tub liner to fit properly. [1]
In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains.
The bathtub curve is a particular shape of a failure rate graph. This graph is used in reliability engineering and deterioration modeling. The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions: The first region has a decreasing failure rate due to early failures.
