Q We're remodeling our master bathroom to include a modern shower stall with all the bells and whistles. My contractor suggested that we go with one of the new type of electronic "digital" shower mixing valves, instead of the traditional manual-type valve. Can you please give me some additional information on these electronic shower valves?

A Digital tub and shower valves are catching on fast. The products are becoming affordable, and a lot easier to install and operate. And they can do much to enhance the bathing experience.

For instance, you can zone off different showerheads and, with the push of a button, change the water direction. Or automatically fill your bathtub to the perfect temperature while you're shaving. Operating controls can also be added outside the shower area, so you can start your shower as soon as you get out of bed, then walk right into a nice hot shower. Bright display screens can show the water temperature and how the water is being controlled.

Bottom line: The gadgetry is wonderful, but just remember that it needs electricity to operate. So in case of a power failure, have a good backup plan so you don't end up high and dry in your shower.

Showerhead terminologyQ I want to install a showerhead and have been trying to choose a new one. But it seems that everyone I talk to has a different term for a showerhead, and there are a lot of choices. Please explain the correct terms so I'll sound like an expert the next time I talk to a salesperson.

A Changing a showerhead is one of those jobs that most do-it-yourselfers want to try. The key is to be properly prepared from the start. With that in mind, here's a basic list of the most popular types of showers:

Single-function showerhead: This is your basic showerhead that attaches to the chrome shower arm sticking out of the wall.

Multifunction showerhead: Installs the same as the single-function, but will have different spray settings, like wide, narrow and/or massage.

Rain showerhead: Usually requires a special installation. This is a wide head designed to be mounted higher.

Body shower spray: Usually requires a special installation. The head is mounted lower on the wall, and sprays out horizontally.

Personal shower: Attaches to the shower arm with a special hanger/bracket. It has a hose so the shower can also be used as a handheld spray.

The "winners" have all been Turkeys, no matter the honor's name.

In this photo taken Monday, March 6, 2017, in San Francisco, released confidential files by The University of California of a sexual misconduct case, like this one against UC Santa Cruz Latin Studies professor Hector Perla is shown. Perla was accused of raping a student during a wine-tasting outing in June 2015. Some of the files are so heavily redacted that on many pages no words are visible. Perla is one of 113 UC employees found to have violated the system's sexual misconduct policies in rece
