Handicap accessible shower
Use of linear drains in barrier free showers is also growing.
However, ensure that your plumbing inspector approves of the product you intend to use.

There are not substantial differences in code requirements. The UPC is written by the International Association of Plumbing and Mechanical Officials (IAPMO) and is prevalent in Western States. The IPC is the plumbing code for the International Code Council (ICC) and is used by most states. There are two primary national plumbing codes: The International Plumbing Code (IPC) and The Uniform Plumbing Code (UPC). Most plumbing officials require that the product be listed by a plumbing code authority. Thin-bed waterproofing membranes must meet ANSI A118.10, which is based on performance rather than membrane thickness and composition. When evaluating membranes, consider durability, ease of installation and performance elements of the products. There are a variety of thin-bed waterproofing products. For example, TS has the lowest moisture/vapor transmission rate (0.050 perms) of commonly specified waterproofing membranes. NobleSeal® TS is widely used in barrier free application because of its durability, record of performance and outstanding test data. However, sheet membranes offer greater uniformity and reduce workmanship variables, which can provide greater assurance of waterproofing integrity. Trowel applied and liquid membranes can offer advantages when the installation involves areas that are oddly shaped. There are various types of thin-bed waterproofing membranes including trowel applied, liquid and sheet membranes. Requirements for thin-bed waterproofing membranes are detailed in ANSI A118.10. After the membrane is bonded to a sloped substrate, tile can be bonded directly to the membrane. Thin bed waterproofing eliminates the need for the 11⁄4” mortar bed and is generally preferred in barrier free showers. The membrane is typically referred to as a shower pan. The mortar bed method requires a reinforced mortar bed (approximately 11⁄4”) over the waterproof membrane. Both methods require that the floor be sloped 1⁄4” to 1⁄2” per foot from perimeters to a drain. Two common methods are used to waterproof showers: mortar bed and thin- bed.
Although not generally required by code, it may be appropriate to waterproof areas adjacent to curbless showers. Since plumbing inspectors interpret codes, it is prudent to confirm your plans with local officials at the outset. Applying those requirements puts the height above the drain for an accessible shower at 11⁄2”. The ADA mandates a maximum height of a threshold of 1⁄2” and requires at least 4’ from the entrance to the drain. Plumbing codes state that the threshold (or high point) in a shower must be at least 2” above the drain. For example, a slope of 1⁄4” to 1⁄2” per foot to the drain is required. There are some areas of conflict between plumbing code and ADA accessibility requirements. The International Code Council (ICC) developed ANSI A117.1 to detail those requirements. Accessible showers have specific requirements mandated in the ADA Guidelines. Plumbing codes apply and installations need to be approved by a plumbing official. Showers get more water than any rainforest, so waterproofing is critical. And, as the name implies, “Transfer Type Showers” facilitate moving from a wheelchair into the shower compartment. “Standard Roll-in Showers” provide wheelchair access. There are 2 basic types of accessible shower compartments. The Americans with Disabilities Act (ADA) delineates “Accessibility Requirements” including size of shower compartments and descriptions of required seats, shower controls and grab bars. However, a handicapped accessible shower must be barrier free. This article should help expand understanding of the regulations for Accessible Showers, relevant plumbing code requirements and information concerning products and methods.Ī barrier free shower does not have to be wheelchair accessible. As baby boomers age, that need is likely to increase. In addition, people with physical impairments may require a barrier free entrance. A shower without a curb can provide a European style, contemporary look and improve accessibility. Barrier free implies that there is no curb or obstruction to entering a shower.
Growth in demand can be related to the appearance created with barrier free construction as well as benefits in functionality. Barrier free showers are growing increasingly popular in the hospitality industry.
