Step 1: Attach the Vanity

Cut out a hole in the backside of the vanity (Image 1) to fit over the pre-installed water supplies and drain.

Securing the unit in place was fairly simple. Long wood screws were used to attach it through the wall into the wall-studs (Image 2).

Step 2: Add Hot and Cold Water Supplies

Adding the hot and cold water supplies was also fairly easy to accomplish. Install the valves right after the rough plumbing is finished. Use flexible lines — with nuts already attached

Step 3: Attach the Top of the Vanity

The solid surface top and sink (Image 1) also had to be special ordered. This unit is amazingly light, weighing about 20 pounds.

The brushed chrome faucet attaches easily with large nuts screwed on from underneath (Image 2).

Step 4: Assemble the Visibile Part of the Sink Drain

Assemble the visible part of the sink drain according to directions, making certain to place a ring of plumber's putty underneath the drain ring. The putty creates a tight seal when the tailpiece is screwed in from the bottom.

Step 5: Connect the Tailpiece to the Drainpipe

Get underneath the sink to make the connection from the tailpiece to the drainpipe (Image 1), using a trap in between. The curved shape of this pipe traps water below the level of the drainpipe. This design prevents sewer gas from seeping back up into the bath while allowing the water to drain out of the sink.

Each connection has a large plastic nut that fits over a nylon washer and is hand tightened on the threads of the adjacent pipe (Image 2).

Step 6: Test the Faucet

Once the connections are all made, it's time test the faucet. Open the valves on the water-supply lines, then remove the faucet filter to allow the lines to clear of any debris.

The faucet is turned on to check for proper operation and make certain there are no leaks.
