Replacing a drop in bathroom sink is not a very time consuming process. A drop-in bathroom sink will enhance the look of the room. There are drop-in bathroom sinks made of different materials. You can make a trip the local hardware store and choose the one that you like best. However, remember to buy one that is the same dimension as your old drop-in sink. If you have all the materials and the appropriate tools the job can be completed in a matter of hours. Here’s how you go about doing the job.

Step 1 - Prep Work

The first step in replacing a drop in bathroom sink is to turn the hot as well as the cold water supply off. If you have extra fittings, like to a garbage disposal, then make sure to cut the power supply to it.

Step 2 - Drain

Make sure to place a bucket under the supply lines, so that the water released while removing the sink can be caught. Drain out any excess water from the faucet by turning it on.

Step 3 - Supply Lines

Before replacing the drop in bathroom sink it is also important to drain the water in the supply lines. Use a wrench to disconnect the lines at the spigot. The water will automatically flow out.

Step 4 - Disassemble

Remove all the drain pipes from the sink area. Remove the clips that hold them to the counter. Use a rubber mallet and a putty knife to release the seal between the counter and the sink.

Step 5 - Remove the Sink

After the grip is released, lift the sink out of the slot. Now attach the faucet to the new drop-in bathroom sink.

Step 6 - Silicone Sealant

Mark the position of the drop in bathroom sink and apply a thin layer of silicone sealant. Now carefully place the new sink in its position.

Step 7 - Excess Silicone

If you observe excess silicone sealant, remove it with the help of a damp cloth or rag. The sealant will take around 60 minutes to harden and set.

Step 8 - Plumber's Putty

The drain flange has to be roped with a plumber's putty. Make sure that the putty has a half-inch thickness.

Step 9 - Replace the Old Tile

Insert the flange into the drop in bathroom sink drains.

Step 10 - Reconnect

Now reconnect all the drains that were dismantled earlier. The drains have to be connected back to the drain pipes.

Step 11 - Pipe Joint

Apply a pipe joint compound on the thread of the supply lines. And follow it up by connecting the supply lines to the faucet.

Step 12 - Finish

If there is excess putty around the drain then make sure to take it out. Turn the spigots on and restore the water supply.
