Observations by an industry veteran on what’s in, what’s out and what’s
the next big thing.

This hands-free faucet has a series of infrared sensors positioned in the acrylic disk near the end of the spout that control temperature and water flow.
I did the ISH thing again in March, heading over to
Frankfurt, Germany, to see what the daddy of all plumbing shows had to excite
the hordes this time. For those who have never attended, the biennial ISH Fair
doesn’t quite line up with any single show we have here in the U.S. in terms of
overall size or product mix. Unlike K/BIS, it includes HVAC and other
nonplumbing categories - and also unlike K/BIS, has very little emphasis on
kitchen products (except for faucet lines that include them in their overall product
offerings). But what plumbing they do have, there is lots of - three large
buildings worth.
The
tour I’m about to take you on will give you a brief look at some of the
significant trends and innovations from my perspective - followed by a more detailed
look at one in particular. Here we go:

What’s really new in the floor valve category are floor-mounted faucets designed for use with lavatories - especially vessel types.
Untrends
Severe angular forms. Two years ago, we saw a
lot of sharp-edged blocks, slabs and bands. I sensed at the time that this was
probably an overreaction to 10 years of too many jelly bean forms, which seems
to have been borne out this time around. While there were plenty of angular
designs, many were already morphing into softer iterations.
Minimalist designs (geometric cylinders and
simple tubes) also seem to be fading.
Holding Steady
“Domesticated” prerinse kitchen faucets. Not many truly new versions this time, but many
of the previous ones. This category appears to be here to stay.
Open channel faucet spouts.
An example of integrating a faucets into a shelf, as well as a drain cover to hide the drain yet still allows water to flow into drain.
Trends
Stainless steel. There were more such faucets evident this time (meaning the real stuff,
not faux plating on brass). Most were from Italian suppliers.
Joystick, flo-thru and cycling faucet mechanisms.
(“Cycling,” sometimes called “progressive,” turns the water on through cold and
delivers increasingly warmer water as you continue the rotation.) In basic
form, cycling faucets do not provide volume control, but there were versions of
flo-thru designs this time that included a secondary control with that function.
In one case, this was a lever coming off a flo-thru rotary control collar, and
in another, it was a rotating flo-thru mechanism just above the aerator.
Lights. There were more examples of faucets
and showerheads that direct light down into the flow; in one case, changing
color to indicate water temperature.
“Shepherd’s crook” shower systems. This is a long length of
tubing, with a big bend at the top, that mounts to the surface of the shower
wall. (This clearly appeals more to the European market, where valving and
connecting water delivery is typically located outside the wall.)
A growing number of shower enclosures have just one wall of glass parallel to the room wall, open at both ends, and no doors.
Faucet shelves. There were more examples of
integrating faucets and tub/shower valves into shelves.
Stanchion (floor-mounted) faucets. While we
have had floor valves for use with free-standing tubs for years in traditional
form, we are now seeing highly styled contemporary designs as well. What’s
really new in this category, though, are floor-mounted faucets designed for use
with lavatories - especially vessel types.
“Galley” showers. This is what I would dub a growing number of
enclosures that have just one wall of glass parallel to the room wall - open at
both ends - and no doors.
There were a lot of examples of mirrors with lights and/or TV screens showing through - even some with iPod ports.
Multifunction mirrors. Lots of examples this time of mirrors that have lights and/or TV
screens showing through - even some with iPod ports.
“Baffle” drain covers. These are covers that hide drain openings in lavatories and showers.
Typically, they take the form of a plate that sits into a recess surrounding
the drain. While covering the drain, they still allow free flow of water into
it.

Although there were some hands-free faucets and shower valves shown at ISH Frankfurt, the trend was more in the direction of touch-button systems.
The Most Electrifying Trend Of All
In the early 1990s
we saw what looked like the beginnings of a movement in electronic faucets and
shower valves - only to see it fizzle in short order. Given time to reflect on
the failure, we generally concluded that many of those earlier generation
offerings were just too complicated and expensive. As someone opined, “To get
yourself a glass of water, you had to make a computer entry.”
With
a number of years to reflect and learn from that false start, industry
engineers have developed a new generation of much simpler, intuitive versions.
(And our exposure to electronic controls on phones, PDAs, MP3 players and the
like during the interval probably sets a better stage for acceptance this time
around.) Though there were some hands-free faucets and shower valves shown at
ISH, the trend was more in the direction of touch-button systems.

Touch-button system incorporated into sprayhead to control water temperature and flow.
Most common were four-button types - providing one
each for the functions of warmer, colder, more flow and less flow. Typically,
these are time-regulated. For example, the longer you keep your finger on the
“warm” button, the warmer the water gets. While most provide infinite temperature selection, there were some that moved from
one set point to another (10 different temperature selections, for instance).
This approach is probably OK for faucets, but I question the suitability for
showering, since our bodies have a very fussy way of defining comfort (and as
little as five degrees off that mark just won’t cut it).
From the
standpoint of technologies employed, most touch-button systems appeared to be
capacitive (sensing via the conductivity of a user’s fingers) or piezo (sensing
minute pressures applied). One manufacturer showed an interesting variation on
the four-button theme by connecting touch buttons with lines that you run your
finger along to the desired temperature or flow settings. A novel twist from
another manufacturer was a faucet with touch buttons located on the pull-out
sprayhead.
One of the
most innovative designs in the hands-free category was one with a series of
infrared sensors positioned around an acrylic disk near the end of the spout.
These sensors control the four basic functions without requiring the user to
touch the faucet (providing time-regulated adjustments and infinite temperature
selection). In addition to water delivery, this faucet also dispensed soap and
disinfectant gel.
