To accommodate ADA clearance dimensions, cover 118 is configured and mounted to reduce or (preferably) minimize spacing between cover 118 and deck 112, basin 158, plumbing 120, and other portions of lavatory system 110. For example, as shown in FIG. 20, a top edge 180 of cover 118 is adjacent (e.g., near or even in contact with) a lower surface 182 of deck 112.

According to an exemplary embodiment, one or more stations are intended to provide an ergonomically correct position for a variety of potential users (e.g., one or more adults, children, persons with disabilities, and combinations thereof). According to a preferred embodiment, basin 158 is configured (shaped, formed, molded, contoured, etc.) to interface with cover 118 to position basin 158 closer to the user and comply with Americans with Disabilities Act (“ADA”) Accessibility Guidelines for Buildings and Facilities and Uniform Accessibility Standards for Lavatories which are herein incorporated by reference) and American National Standards Institute (ANSI) Z124.3 and Z124.6 (which are herein incorporated by reference) so that the user is not required to reach as far to operate the faucet, place hands under running water (or in sink area), or the like, and still provide a conventionally sized sink area. The configuration of basin 158 is also intended to minimize the space occupied by lavatory system 110 in the room or space that it resides (e.g., washroom, restroom, bathroom, hallway, shop floor, and other industrial, commercial, and/or private spaces).

According to an exemplary embodiment, the lavatory systems are configured to comply with ADA guidelines (adult and juvenile) and/or other accessibility guidelines. As shown in FIG. 20, a block 192 is shown to illustrate accessibility clearances in compliance with ADA guidelines. Block 192 includes a deck counter surface height H1, a deck clearance height H2 from the floor to the apron, a knee clearance height H3 from the floor to the underneath of the lavatory (i.e., the cover shown in the FIGURES), a toe clearance height H4, a clear floor space, a total clearance depth D1, and a knee clearance depth D2.

Under current ADA adult guidelines, a lavatory is to be provided with H1 being no higher than 34 inches (865 millimeters), H2 being a minimum of 29 inches (735 millimeters), H3 being a minimum of 27 inches (685 millimeters), H4 being a minimum of 8 inches (205 millimeters), D1 being a minimum of 17 inches (430 millimeters), D2 being a minimum of 8 inches (205 millimeters), and if a minimum of 9 inches (230 millimeters) of toe clearance is provided, a maximum of 6 inches (150 millimeters) of the 48 inches (1220 millimeters) of clear floor space required at the fixture may extend into the toe space. Under ADA children or juvenile guidelines, a lavatory is to be provided with an apron clearance and a knee clearance (H2) of 24 inches (610 millimeters) minimum and a rim or counter surface height (H1) of 31 inches (760 millimeters) maximum. According to a particularly preferred embodiment, the ADA adult compliant station has a deck 178 between 32 inches and 34 inches above the floor and 22 inches from the wall, an apron 30 inches above the floor, a cover 12.25 inches above the floor. According to a particularly preferred embodiment, the ADA juvenile compliant station has a deck 178 that is 31 inches above the floor and 22 inches from the wall, an apron 27 inches above the floor, a cover 9.25 inches above the floor.

As shown in FIGS. 19 and 20, one or more stations of the lavatory system is mounted at a height that is designed to comply with the accessibility guidelines. According to an exemplary embodiment, the cover and basin are configured (e.g., shaped, orientated, etc.) to provide space beneath the deck for block 192 in compliance with accessibility guidelines. Referring to FIG. 20, basin 158 includes a front wall 184, a rear wall 186, a pair of sidewalls 188, and an overflow opening 189. As illustrated with clearance block 192, the user is able to be positioned closer to the sink area as cover 118 is not disposed as far from wall 128 if front wall 184 was not contoured. According to an exemplary embodiment, cover 118 includes a concave portion 190 (e.g., an indentation or the like). According to a preferred embodiment, front wall 184 of basin 158 is configured (e.g., shaped, designed, orientated, etc.) to conform with the cover. According to an exemplary embodiment, front wall 184 is contoured to provide space beneath deck 112 so that the user (e.g., if seated in a wheelchair) would not have to reach as far to place hands over basin 158. According to a preferred embodiment, the contour of front wall 184 projects into the area defined by basin 158. According to a particularly preferred embodiment, front wall 184 is at least partially “convex” so that front wall 184 project or curves into the sink area. As such, the lavatory system is configured to use space more efficiently (e.g., fit and design of deck, sink, cover, and/or walls), and provide improved access to and useability of the lavatory system for users having varying physical attributes or abilities to attend to their washing needs.

FIGS. 10-12 show a lavatory system with three stations (shown as an upper station, an upper station, and a lower station). The upper stations include an upper surface that is offset (i.e., vertically and laterally) from an upper surface of the lower station. As such, the lower station is configured to comply with ANSI, ADA, and/or other accessibility standards. The upper stations of the lavatory system are configured to provide comfortable and convenient accessibility to persons having other physical abilities. According to an alternative embodiment, the lavatory system includes two stations with upper surfaces that are vertically offset lower than the upper surface of the third station. According to an alternative embodiment, the lavatory system includes stations that have three (or more) different upper surface heights (e.g., to accommodate three potential users having three different physical abilities, such as standard, ADA adult, and ADA juvenile). According to an alternative embodiment, the lavatory system includes two adjacent stations with upper surfaces that are vertically offset lower than the upper surface of the third station (e.g., at the same or different heights). These two adjacent stations may be located at either end or side of the lavatory system (e.g., left or right). According to alternative embodiments, the lavatory system may have any of a variety of combinations of “higher” or “lower” stations arranged in any of a variety of order or configuration. According to further alternative embodiments, the lavatory may have any number of stations arranged at two or more heights.

According to a particularly preferred embodiment shown in FIGS. 19 and 20, the deck (including the apron and backsplash) and basin are molded or cast as an integral or one-piece component using solid surface material. According to an alternative embodiment, the deck can be cast or molded as two or more components that are assembled.
