Bathroom doors are ordinarily not as wide
as bedroom doors. A door width of 2′-6″ or
even 2′-4″ is usually sufficient. If provisions
are being made for wheelchair use, then the
door should be a minimum of 2′-8″ wide.
Doors should swing into the bathroom and not
interfere with any fixtures. In some instances,
a pocket door is used to subdivide the bath
into two or more areas, as in a two-compart-
ment bath, Figure 7-21.
Primary Fixtures
The three primary fixtures found in most
bathrooms are the lavatory, water closet
(toilet), and tub or shower. The arrangement of
the fixtures determines whether or not the bath
is truly functional. For example, avoid locating
the lavatory or water closet under a window.
Provide ample space for each fixture in the
room. Bathroom fixtures vary in size as shown
in Figure 7-22. Check the manufacturer’s specifi-
cations and code requirements for placement
of each of the fixtures.
A mirror should be placed above the sink,
Figure 7-23. Arrange the mirror so it will be
well lighted and away from the tub to prevent
fogging. The mirror should be tilted slightly
downward for full viewing or be mounted low
enough for a wheelchair user to see. Another
