The washbasin, which comes in various shapes and hues, is an essential component of any bathroom. Installing a washbasin, whether free-standing or built-in, is very simple but more difficult for suspended models. Rigor and precision are then required for a successful installation.

Step 1: Install the drain.

    – Turn off the water at the house’s main faucet.

    – Since the washbasin is easily accessible, mainly its underside, take advantage of this to install the drain.

    – Place the gasket over the hole in the washbasin.

    – Place the grate over the gasket.

    – Place the gasket on the other side (below the washbasin) on the part of the drain that includes the thread.

    – Tighten the clamping ring by hand.

Tip: to reinforce the seal, put a bead of sanitary silicone sealant around the hole in the washbasin before placing the gasket.

Step 2: Install the mixer.

Before fixing the basin to the wall, it is better to install the mixer tap, as the clamping elements are much more accessible.

    – Connect the water supply hoses to the mixer.

    – Tighten by hand and then with a wrench.

    – Screw the threaded rod by hand to the dedicated location and tighten with a flat screwdriver.

    – Insert the drain valve into the hole at the back of the mixer and screw the bottom part of it in.

    – Slide the base gasket and fitting over the pull tab and the two hoses as far as the stop on the mixer.

    – Insert the hoses and the pull cord into the hole in the washbasin.

    – From underneath the washbasin, install the gasket, the retaining flange, and the lock nut.

    – Place the mixer properly on the washbasin, keeping it flat and aligned.

    – Screw on the nut with a wrench while holding the mixer.

Step 3: Install the waste system.

Unscrew the lower part of the drain valve.

    – Remove the ring screwed on the drain.

    – Place the drain pin in the ring and screw it back onto the drain.

    – Screw the lower part of the pull tab back onto the upper part.

    – Connect the pull cord and the drain shaft with the connecting clevis.

    – Tighten the screw of the connecting clevis with a screwdriver to block the whole.

    – Insert the valve into the hole in the drain.

    – Test the drain system by operating the pull tab on the back of the mixer.

    – Adjust the connecting clevis if necessary with the screw.

Good to know: the connecting clevis should be slightly lower than the drain connection when the pull knob is in the closed position.

Step 4: Fix the washbasin.

A template is usually supplied with it to facilitate the installation of the washbasin.

    – Place the template on the wall at the desired location.

    – Check that it is horizontal using a spirit level.

    – Mark the mounting points with a pencil.

    – Drill at the location of the markings with a drill bit adapted to the size of the chosen plugs.

    – Insert in the holes, plugs adapted to the nature of your wall (hollow or solid partition…).

    – Screw the threaded rods (supplied) into the plugs with a wrench.

    – Screw the nuts on the threaded rods with a flat wrench.

Step 5: Connect to the water circuit.

    – Screw the hoses of the mixing valve onto the water inlets, making sure that the hot and cold directions are matched. Tighten by hand and then with a wrench.

    – Connect the washbasin trap to the drain.

    – Turn on the water supply at the main tap.

    – Check for leaks.
