Many large showers are being built sans doors. It eliminates the floor space you need for door clearance—and a non-existent door is certainly easier to clean! But remember that a shower door is about more than keeping water off your bathroom floor. That barrier keeps warmth and humidity inside the shower enclosure, and keeps cold drafts from entering while you lather up. In a doorless shower, you may feel cold despite the heat of the water, and you’ll start yearning for a shower curtain.
