Bathrooms today are more technological than ever before, according to a Houzz Bathroom Trends Report.

Walk into a newly remodeled bathroom, and you can expect to see hands-free faucets, wired toilets, built-in TVs, and showers and baths that can do everything from dole out aromatherapy and light therapy to adjust the temperature, depending on who is using it.

One in five toilets in renovated master bathrooms already has a high-tech feature, the Houzz report found, and bathroom technology is snowballing with a self-cleaning toilet (43 percent), built-in bathtub lighting (64 percent) and shower lighting (60 percent) being the top high-tech features, according to the report.

It has become increasingly popular in recent years, as people's lives have gotten more integrated with their electronics, said Jamie Gold, a San Diego-based designer who is writing a book about bathrooms that will have a section on electronics in bathrooms. "The expectation is that your phone goes everywhere you go, providing news and entertainment while you get ready for your day or wind down at its end. As bathrooms have evolved from basic spaces to personal retreats, technology has evolved to enhance them."

But as bathroom remodeling continues to embrace technology — the Virginia Tech Center for Design Research created a FutureHaus Bathroom predicting bathrooms with flooring that sends out alerts if someone falls — there are also options for those concerned that technology is changing so quickly that by the time they finish their bathroom remodeling project, the technology will be outdated.

One of those options is the high-tech toilet, said Nino Sitchinava, principal economist at Houzz.

She said that buyers can choose self-cleaning toilets, toilets with built-in nightlights, heated seats, motion-activated seats, self-deodorizers, hands-free flushing or those with overflow protection.

Showers are another area where homeowners can add technology sans a rehab, said Alan Zielinski, president of Better Kitchens Inc.

He suggested the new Moxie Showerhead & Wireless Speaker by Kohler (starts at $299 at us.kohler.com), which offers plenty of easy technology.

"It replaces an existing shower head and provides you with music via Bluetooth from your iPhone or favorite personal smart device," Zielinski said. "The waterproof speaker is easily removed for charging and can be moved anywhere within range of the Bluetooth device, so your music can move with you, hands-free, to your dressing area."

Lighting doesn't have to be permanent, either.

With the advent of so much bathroom technology, many homeowners are also adding Docking Drawers (starting at $239 for a charging outlet and $259 for a power outlet at dockingdrawer.com), which incorporate outlets and charging stations discreetly into vanity drawers for blow dryers, phones, tablets and anything else, Zielinski said.
