Once the carcass has been
plumbed and levelled, the
back rail of the cabinet is
screw fixed to the stud wall.
It is advisable to use at least
two fixings in the length of
the rail, to provide solid and
stable attachment.
The bottom rail, if present, is
also screwed to the stud wall
or the base of the cabinet
may be screwed to the solid
plinth underneath.
If the vanity top does not have a
built-in or moulded upturn at the
back, to prevent water passing
behind the cabinet, then a flashing
should be installed.
The flashing may be in the form of:
� An ’L-shaped’ non-corrosive
metal or plastic flashing strip
fitted to the wall on top of the
cabinet fixing rail, before the
top is secured;
� An ’L-shaped’ non-corrosive
metal or plastic flashing strip
cut into the back edge of the
top, before the top is fitted; or
� A full length bead of flexible
waterproof sealant applied
between the fitted top and the
wall lining.
