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 United States in terms of overall size or product mix. Unlike K/BIS, it includes HVAC and other non-plumbing categories - and also unlike K/BIS, it 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
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 jellybean 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.
pre-rinse 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.
steel. There were more such faucets evident this time (meaning the real
stuff, not faux plating on brass). Most were from Italian suppliers.
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.
There were more examples of faucets and showerheads that direct light down
into the flow, in one case, changing color to indicate water temperature.
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.)
shelves. There were more examples of integrating faucets and tub/shower
valves into shelves.
(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.
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.
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.
The Most Electrifying Trend Of AllIn the earl-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. 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.
