Replacing Bathroom Sink: Removing the Old Sink
Replacing bathroom sink is something you can do yourself if you are reasonably handy and have the following tools: a pipe wrench and an adjustable wrench, a strong, thin bar to pry the old sink away from the wall, if you are removing the counter top. You will also need a screwdriver, silicone caulking, a sharp knife and a tape measure.
If your new sink is of the same size or slightly larger than the one you are replacing, you will merely have to clean up the area. If not, you will need the tools for neatly repairing and/or re-tiling the wall and floor where the old sink stood.
If you have a new counter top, or you need to re-cut the hole for a new drop in or undermount sink, you will need a pencil, a template, a drill to make a starter hole, and a saber saw to cut out along the pencil mark.
When replacing bathroom sink, first of all you need to disconnect the plumbing from the old sink.
Turn off the water supply, either at the shutoff valves beneath the sink, or if there are none, turn off the main water supply. Empty the pipes by turning on the faucets. Now you need to put a large basin under the trap to catch the remaining waste water, before you loosen the nuts and remove the trap and the tailpiece. After this you can undo the supply lines at the faucet end, leaving them to connect up to the new sink.
If you are replacing a wall mounted or pedestal mounted bathroom sink, you can now cut away the old caulking from the back edge of the sink. Loosen the pedestal nuts if it has any and chip away the tile cement that holds the pedestal to the floor. Lever the sink away from the wall with the screwdriver and/or bar, and remove it. Be careful, it can be very heavy as it comes away!
If you are replacing a countertop bathroom sink you will either remove and replace the whole countertop or just replace the sink.For undermount sinks, cut away the old caulking that seals the sink and remove the clips that hold the sink in place. A drop in sink needs you to remove the old caulking and pry the old sink out. If you are removing the whole countertop, you will need to undo the brackets that hold it to the wall and cut away the old caulking where the back of the countertop meets the wall.
Replacing Bathroom Sink : Installing the New Sink
Most people find that it is easier to install the drain fittings and faucets before replacing the bathroom sink. Put some plumber’s putty or a nice thick layer of caulking between the drain flange and the inside of the sink. Then put in the drain assembly and turn the sink over. Now you can put in another layer of caulking between the washer and the underside of the sink. Tighten the nut that locks the assembly into place until some of the caulking squeezes out, to get a nice tight seal. Install the faucets as per the instructions.
If you are not reusing the old counter top, or if the sink is slightly bigger, you will have to cut a hole in it for either a drop in or an undermount sink. When you buy your new sink, you should ask for a template to mark out the hole. When the hole is ready, you can replace the bathroom sink. With a drop in sink you need to run a bead of caulking along the underside of the rim of the sink and lower it firmly into place. With an undermount sink, you run the bead along the top of the rim and then fasten it into place with new clips.
If you are replacing bathroom sink with a wall mounted or pedestal type, you will have to either fasten it to the wall with brackets, or replace the pedestal with bolts and/or tile adhesive to the floor.
You will need to replace the caulking along the line where the sink or counter meets the wall to seal it and finish it off.
Join up the old water supply lines to the new faucet tailpieces. At this stage, you may like to include new shutoff valves, if you have none. They are so useful for any future repairs or alterations to the faucets.
Connect the trap to the wall drain outlet and the drain assembly on the sink. Check that everything is tight and firm, then turn on the water and check for leaks.
