Among the many advantages
that solid surface materials offer to countertop fabricators and ultimately to homeowners
is the relative ease of creating a wide variety of decorative edge details. In this
regard, solid surface materials are much more versatile than other common countertop
materials and the possibilities are limited only by the imagination of the designer,
fabricator or homeowner.
However, it is safe to say that a few "favorite
themes" have emerged as the industry has matured, and that some edges are much
more popular than others. On occasion, I have made rough estimates of the frequency
that various edges occur in the marketplace based on my personal experience and memory.
For this column, I decided to do a more representative survey. I selected, at random,
exactly 100 solid surface countertops with fabricated decorative edges that I've
inspected in the past year or so, and compiled a list of all of the different edge
details involved. Accordingly, this column accurately describes a representative
sample of Northern California installations completed by dozens of different fabricators.
It is perhaps not surprising that the most common edge detail I observed was also
among the easiest to fabricate and the one commonly sold by fabricators at no extra
charge. I am referring to a simple rectangular apron edge, fabricated out of the
same color of solid surface material as the rest of the countertop, and usually measuring
either 1-1/4" or 1-1/2" thick. This edge occurred in 32%, or nearly one-third,
of the installations I inspected. The edge detail is finished off with a routed roundover
on the top and sometimes the bottom, and the radius of this roundover varies from
a barely perceptible 1/16" for a visually square appearance to as much as 1/2"
for a much softer, more rounded appearance.
One variation that occurred in 3%
of the installations was a 45ø bevel on the top edge rather than a radiused roundover.
This edge creates extra visual interest as the bevel travels along radiused inside
and outside corners. Occasionally, a fabricator will bevel the outside corners in
two dimensions, creating a distinctive faceted effect.
The edge called either
the full bullnose or the 180ø radius occurred 16% of the time. Most fabricators charge
extra for this edge, because it usually requires more labor to cut and glue up, more
precise router work, and more extensive sanding than a simple rectangular apron.
Routed Roman ogee or standard ogee edges occurred 19% of the time in my survey. Use
of these routed profiles adds a lot of visual interest and a more classical look,
but I have had a number of customers comment that this type of edge is more difficult
to keep clean, because kitchen grime tends to accumulate in the recesses of these
profiles. It is advisable to use a sharp, well maintained router bit for this type
of edge. It is much more time consuming to sand out an imperfection in an ogee edge
than in a simple roundover edge.
A fairly simple way to add dramatic visual interest
to a countertop is to build up a decorative edge with three stacked layers of solid
surface material, with the middle of the three made of a contrasting color or pattern.
This technique was used in 14% of the installations I observed. Often, the accent
color was selected to match or complement other design elements in the kitchen -
paint or wallpaper, cabinet pulls or plumbing fixtures. One benefit to the fabricator
is that the color shift tends to conceal an occasional minor imperfection in the
seam between the layers that make up the edge.
In 16% of the countertops I inspected,
a decorative wood accent to match the cabinets was incorporated into the edge detail.
Most of the time, the species was red oak, although I inspected one where maple was
used, and another where cherry was used. I also observed one installation where a
polished brass inlay was used and another where brightly colored acrylic was used.
For reasons of structural integrity, it is recommended that a wood accent be in the
form of an inlay into the front of a thick edge built up ahead of time out of solid
surface material, rather than a piece of solid wood sandwiched between two separate
pieces of solid surface material. Because wood expands and contracts significantly
with changes in moisture whereas solid surface materials expand and contract with
changes in temperature, a sandwiched assembly may well be an unstable one. There
is no doubt, after all, that a kitchen countertop must withstand dramatic changes
in moisture and temperature.
In one case, a serious problem developed when a
fabricator combined an oak inlay with a large routed Roman ogee profile. The routed
ogee pattern left a very narrow and sharp fin of solid surface material sitting just
above the oak. The look was nice, but in service in a working kitchen, the shortcoming
quickly emerged. Any glancing impact chipped the edge right where the thin piece
of solid surface material met the wood.
The "no drip" edge, so common
in with mass-produced plastic laminate countertops, was seen in just 3% of the solid
surface countertops. This is a particularly labor intensive edge detail that requires
skill and experience to get just right, especially at radiused inside corners.
Finally, I saw three edge details that I would describe as "highly unique".
In one case, a fabricator routed an ogee on the edge of a 1/2" thick slab of
white solid surface material, and then bonded this slab to a 1" thick 180ø polished
bullnose molding made of a very dark granite patterned solid surface material. Another
fabricator used a router bit similar to one that would be used to make finger joints
in wood to create a deeply textured front edge. The final one was my favorite - the
deck was a light gray granite-like pattern, and a very dark burgundy granite patterned
edge molding was bonded to the front, with the seam falling on the horizontal surface
1" back from the front edge. A 1/4" wide inlay of a third solid surface
material, a milky white pattern, served as an accent stripe between the two speckled
patterns, and the countertop was polished to a beautiful luster.
I think that
the most notable statistic I gleaned from this survey is that 66%, or almost exactly
2/3 of these installations, were fabricated out of a single pattern or color of solid
surface material. The remaining 1/3 accounted for all of the installations that included
two or more colors of solid surface material, or incorporated other materials such
as wood, metal or acrylic into the edge detail.
So is the cup two-thirds empty
or one-third full? I've long observed that people tend to be pretty conservative
when making kitchen design decisions. An overly flamboyant blouse or neck tie can
be retired to the closet, but most people only have one kitchen and they expect it
to serve them for many years or even decades. In my view, special congratulations
are in order for the 3% or so of customers who select a decorative edge that is knock-your-socks-off
distinctive.
