Hansgrohe 4778000 Joleena Base Plate Single-hole Chrome

Product Description

The HANSGROHE 4778000 is a deck-mounted base plate designed to allow single-hole faucet installation in an existing multi-hole sink or countertop cutout. It covers unused holes in a three-hole or similar multi-hole deck configuration, providing a clean, finished appearance around a single-hole faucet body. The plate ships in a Chrome finish and is part of the Joleena faucet collection. Licensed plumbers and finish trim installers typically handle this fitting during new construction or bathroom remodel projects where a single-hole faucet is being retrofitted into an older multi-hole deck.

This base plate is used in residential bathroom sink installations where the countertop or sink deck has pre-drilled multi-hole configurations but the selected faucet requires only a single mounting hole. It is a finishing accessory within the Joleena collection and is intended for use alongside compatible Joleena single-hole lavatory faucets. The transitional styling of the Joleena line suits both contemporary and traditionally influenced bath settings.

Key Features

• Covers unused deck holes when installing a single-hole faucet in a multi-hole setup
• Chrome finish for corrosion resistance and easy cleaning
• Part of the coordinated Joleena faucet collection for consistent aesthetic
• Designed for deck-mount lavatory faucet applications

Compatibility

Designed for use with Joleena series single-hole lavatory faucets from HANSGROHE as a deck cover plate for multi-hole sink installations.

Installation Notes

Installation is typically performed by a licensed plumber during lavatory faucet rough-in or finish trim. Shut off the water supply valves beneath the sink before beginning any faucet or accessory installation. Verify that the base plate seats flush against the deck surface and that the single-hole faucet shank passes cleanly through the center opening before tightening any hardware. Follow local plumbing code requirements for fixture installation.
