Step 1: Attach the Supply Lines

The faucet is tightened from below and the diverter is tightened (Image 1).

Add the valve stems for the handles (Image 2), and then the water supply lines (Image 3).

For this project, Teflon tape was not needed. The connections come with a rubber gasket inside creating the watertight seal (Image 4). They tighten on with a wrench.

Step 2: Thread the Drain Stem

Roll out plumber’s putty for around the drain plate (Image 1), and thread the drain stem on from below the sink (Image 2).

Set the sink in the right spot (Image 3), use a level to get the exact placement and mark the location of the bolt holes in the back of the sink.

Step 3: Drill the Tile and Secure the Sink

To drill into the tile, use a tile bit on the drill starting out slow and pushing until it goes through.

With a smaller drill bit, finish the hole (Image 1).

Run silicone all the way around the back of the sink as an extra adhesive to back up the bolts.

The bolts drop through the holes. Tighten them down with a tiny wrench (Image 2).

Step 4: Secure the Closet Bolts on the Toilet

Set the rubber ring to create a watertight seal and to protect the porcelain on both the tank and the bowl (Image 1).

Drop the bolts into the tank, mounting the holes and tightening the nuts from below (Image 2).

Tighten down the mounting screws from above while holding the nuts underneath (Image 3).

Step 5: Place the Toilet on the Wax Ring

With the closet bolts in place, set in a new wax ring.

Bring in the toilet, setting over the bolts, pushing it down over the ring.

Step 6: Secure the Toilet

Over the bolts, drop a plastic ring, then a washer and a nut to tighten down to the floor (Image 1).

Hook up the water line (Image 2).
