LAS VEGAS — A grab bar for the bathroom shower that makes you think “pretty” before “old.” A kitchen drawer for trash that makes you think “wow” before “useful.” A kitchen faucet with temperature presets that says “looks elegant” before “avoids burns.”

And then there were the toilets. Technology — certainly for fun and in some cases to impress — was everywhere at the recent Kitchen & Bath Industry Show. But often behind the LED-lighted musical commodes and cool automatic faucets was an effort to make daily life easier for all ages and abilities without sacrificing aesthetics.

There's been a “night and day difference” in the last five years in what's being offered to enable people to “age in place” without feeling that their home has been turned into a hospital, said Mary Jo Peterson, whose Connecticut-based interiors firm specializes in accessible design.

“Manufacturers are waking up and saying, ‘I need to do something to be part of the market for universal design, a concept that refers to designing for people of every age and ability,'” said Peterson.

Salice was among several companies that displayed automated cupboard doors that require no handles. Europeans have been using them for years, but only recently have they become popular in this country, said Dennis Bean, a Salice sales official.

Just changing the color inside a drawer makes its contents easier to see. Lighted floor tiles, induction stoves and oversize shower stalls also were shown.

Installing LED strips around medicine cabinets or in drawers and cabinets, a trend at the show, also can help people see what's inside more easily. LEDs don't get hot, and they're discreet and efficient, said Daryl Nauman, regional account manager for Hafele, a high-end kitchen hardware company.

Hafele's booth held a number of clever solutions, including a step stool that can be installed under a cabinet. With a light kick, it slides out for use.

Drawer Box Specialties, a company in Orange, Calif., introduced its Helping Hands trash drawer that opens by touch and closes automatically.

“I'm getting older, and I don't have the strength I had. And it's not going to get better,” said chief executive Glen Blankenship, who is 70 and created it in part with himself in mind.

Kohler showed its Elevance Rising Wall Bath. One side of the tub can be raised and lowered, with minimum pressure. Another tub had a protruding seat that someone could use to transfer himself from a wheelchair, ideally without help. Or a parent could sit there to wash children.

Delta introduced a battery-operated faucet that senses the body's electric current and turns on if a human is within four inches. It turns off immediately with a touch or in a minute if you walk away — good for young and old alike, spokeswoman Mary McCullough said.

There's no question that the aging of the baby boom generation has fueled many such design innovations. People who no longer can get at pots and pans easily or set out a spread for a party might feel less confident and less inclined to entertain. That starts to isolate them.

Not so long ago, Peterson said, colleagues would react to her commitment to universal design by saying, “That's nice, honey. You take care of those people and we'll design for everyone.”

That doesn't happen anymore, she said.

That's in part because more homes are multigenerational. Four million U.S. households have three generations in them, Peterson said, citing U.S. Census data. And every day, as many as 10,000 baby boomers are turning 65. Remodeling can make economic sense when compared with the cost of in-home care, assisted living or nursing homes.

Not only are baby boomers entering retirement, but the economic downturn has affected who might be doing renovations.

“Slowly but surely, the U.S. home improvement industry is emerging from its worst downturn since the government began tracking spending in the early 1960s,” the Joint Center for Housing Studies at Harvard University said in a January report.

The report found that older people are among the industry's strongest segments.

Officials at Blum, which makes kitchen cabinet hardware, realized that it's not easy to understand people's differing needs. So it uses an Age Explorer suit developed by a German firm that studies aging. With the suit and its accessories — weights, earphones, glasses, gloves, bandages — a person can feel what it's like to be about 70, said Debbie Cannon, marketing services manager at Blum. The suit restricts the wearer's range of motion, joint function, hearing, finger sensitivity and peripheral vision. It makes it difficult to pick up small items from the counter, reach high into cupboards, distinguish among items of similar color and bend down.

Roberta Kravette, a New York designer who wore the suit for a demonstration, found she couldn't open a plastic box and found it difficult to get a toaster from a low shelf. She hit her head when she tried to take a pile of plates from a cupboard. Overall, she said, she felt dizzy and uncertain.

Such research has led to Blum's drawer, which holds stacks of plates and makes them easier to lift out than plates in a cabinet above shoulder height, Cannon said. Her company also showed a cupboard whose door swings upward and then closes by pushing an easy-to-reach button, as well as drawers that open all the way, so every bit of space can be used.

Blum and several other companies showed cupboards that open with a touch of the knee. Many of these ideas would be welcome by pregnant women or someone with a broken arm as well, Cannon noted.
