Bathroom Sinks

Over the years, there have been countless styles of bathroom sinks, countertops, and faucets available. From pedestal sinks, to wall hung sinks, custom cabinets of all shapes and styles. There are, however, a few very common similarities that most of them share.

One of the most common features is that most bathroom faucets are 4" center faucets. There are some uncommon ones, but this means that the distance between the two main mounting holes are 4" from center to center. This allows for any standard 4" faucet to be installed in that countertop.

Both of the above faucets, including the one at the top, are 4" center faucets. They are all interchangeable.

The Basin Wrench

The basin wrench(the picture to the left) is a necessity for changing out any faucet. There are some exceptions, but generally, it is near impossible do it without the help of a basin wrench. The wrench head swivels, so that the head is at a 90° angle to the wrench stem. The head is swiveled in one direction to loosen nuts, and the other to tighten nuts.

The basin wrench in use. It is in the tightening position.

The next common trait that most bathroom sinks share is that they overflows(the little hole near the top of the sink) which require the use of a "pop up" assembly.

Above is a picture of a "standard" pop up assembly. Unfortunately, while all the pop ups do the same job, how they go together can be quite different. The linkage in the back(on the left) is part of all pop ups. It gets connected to the rod that comes down from the faucet. The horizontal rod(with the white ball) goes into the pop up itself, and goes through the hole in the bottom of the stopper.

Tip: It is often possible to install the stopper so that it rests on top of the horizontal rod. This allows for the stopper to be easily pulled out later. Where the rod goes into the pipe, it sits in the middle of the pipe and can collect hair over time, leading to a clog. If the stopper is left loose, you can pull it out an easily check for(and fix) a clog at that point. After one time having found $2.13 in pennies, nickels, and dimes in a sink trap, it might be safer to mount the stopper properly in the rod if you have small, active children though. The choice is yours.

A few more common things with pop ups are that normally plumbers putty is used to seal the top joint at the sink itself. Roll the putty into a "worm" shape and stick it around the underneath lip of the top piece. This could be a separate piece or a long shank that goes down through the sink.

Another is the tapered black rubber seal below the sink. This should go tapered side up so that it compresses in against the pipe as well up to the sink. Below that seal there is an extension tube that is 1 1/4" slip joint(see the slip joint section Here.) Sometimes this has a tapered washer for it. If it is just a metal threaded tube, it needs to be tape doped.
