Everything else is digital, so why not the shower? The ioDIGITAL system gives users the ability to set and maintain water temperature and flow with an electronic touchpad. The system can activate the shower, tub filler, or spa and will accept up to four presets so family members can each have their own setting. The keypad is available in three finishes. Cost: $1,200 to $2,500. Moen. 800-289-6636. www.moen.com.
