Shower Door Knobs and Handles

Matte Black "Penny" Round Glass Shower Knob

$8900
Taxes and shipping calculated at checkout.

The Penny Round Glass Shower Knob brings a clean, architectural look to frameless shower doors with its matte black finish and balanced circular profile. Unlike a simple flat shower knob, Penny features a broad round face framed by a softly raised rim, a stepped center connection, and a coordinating circular back piece. These layered details give the knob visual depth while maintaining the streamlined appearance of modern matte black shower hardware.

Designed specifically for glass shower doors, the Penny knob offers a compact alternative to a full-length shower handle while providing an easy grip from either side of the glass. Its understated geometry works especially well with frameless enclosures and bathrooms featuring black shower hinges, faucets, or other fixtures. The classic round shape also allows this matte black shower door knob to transition easily between modern, transitional, and more traditional bathroom designs.

How to measure cabinet hardware?

To measure cabinet hardware like handles or pulls, you mainly need to know the center-to-center (C-C) measurement—the distance between the centers of the two screw holes. Here’s a quick guide:

For Pulls (Handles):
Measure from the center of one screw hole to the center of the other. This is usually given in millimeters or inches (e.g., 96 mm or 3-3/4").

Tip: Don’t measure the total length unless specified—it’s not the same as the center-to-center distance.

For Knobs:
No measuring is needed for hole spacing—just check the knob’s diameter and projection (how far it sticks out from the cabinet).
