Rough Top for Tile and Stone

Rough Top may
be specifi ed at different
thicknesses.
3/4”
Rough Top is the material
used to cover cabinets
that will help strengthen
the cabinetry and support
the countertop
installation.
Flush
at Side
1/2”
Overhang
at Face
For Tile
It is critical that this
material is installed care-
fully and within standards
as the life of the
countertop material
depends on it.
This material is usually
specifi ed as 3/4” or 5/8”
exterior grade plywood
panels and must be cut
to fi t the installed cabi-
nets by the installer.
5/8”
Cabinet installations that
are to support a mortar
and tile countertop will
utilize Rough Top mate-
rial that is 3/4” thick.
Cabinet installations that
are to be covered with
slab stone such as gran-
ite or quartz will use 5/8”
thick Tough Top.
For tile, index the Rough
Top 1/2” forward of the
cabinet face and fl ush to
the cabinet sides.
