4.5" Shower Drain Cover — Round Flush Mount Replacement (Drop-In / Screw Mount)

Description:

This is a custom designed replacement shower drain cover for 4.5" drain openings. Designed to fit the opening better than a standard off-the-shelf cover, this drop-in disc sits flush against the shower floor and can be secured with silicone around the edges or screwed directly into the existing drain body hardware underneath.

Features a circular hole pattern for water flow and two mounting holes near the outer edge for optional screw installation. Centering locators on the underside help position the cover correctly over the drain opening.

Features:

• 4.5" outer diameter, approximately 2mm thick — low profile flush mount

• Circular hole pattern for water drainage

• Two screw mounting holes — use existing hardware or drill out to fit your screws

• Centering locators on underside for easy alignment

• Silicone around edges recommended to seal and secure

Printing Recommendations:

• Layer height: 0.2 mm

• Infill: 40%

• Filament: PETG recommended for moisture and heat resistance

• Supports: Not required

• Orientation: Print face-down due to centering locators on underside

Installation:

1. Print face-down as oriented

2. Test fit over your drain opening using the centering locators to align

3. Secure with screws into existing drain hardware, or apply silicone around the edges and press into place

4. Allow silicone to cure per manufacturer instructions if used

Notes:

• Designed to replace non-standard or missing shower drain covers
