Choosing a Bathroom Faucets Replacement
Chrome is probably the most durable &amp; is the cheapest manufacturing process. Brushed nickel has a Satin type of finish rather than chrome's mirror finish &amp; bronze is outright dark. The look you're after is really the only concern for finishes &amp; all will hold up very long to wipe off cleaning no problem.

As far low-quality goes I'd stay away from the cheapest faucets which are usually plastic. Typically, the best way to tell this beyond a box or website description is by the mounting or underside's large threaded tube(s) being plastic. But some plastic faucets have begun to put a brass tube(s) on for the mounting so be wary.

Medium to Highest quality is brass to stainless steel &amp; they're noticeably heavier than the plastic faucets. Medium quality brass is what you've had for 30-years &amp; is quite good &amp; good for water purity. Brass or stainless steel will be the faucet's underside threaded tube(s).

I personally prefer Single Handle faucets everywhere as the faucet can be left in the last position for the most comfort &amp; convenience. Two-handles (typically 4-inch spread, measure yours) are fine but in either case look for Ceramic Disc valves to enjoy the best maintenance free longevity. I've had exceedingly good results with the American Standard &amp; Vigo brands for baths &amp; pretty much just Vigo for kitchens.

Finally, you'll need to decide if you want a Full-Kit to replace your sink drain &amp; pop-up stopper. A problem you will run into is connecting the new faucet(s) to the plumbing &amp; you'll need a plumber to install his/her recommended faucet(s) or the faucet(s) you've purchased. The new faucets use "Sold Separately" stainless steel braided flexible lines where you probably have rigid or hard lines now.

The conversion is best done by finally swapping-out your old shut-off valves under the sink (if you have any) for new Quarter-Turn Ball Valve types (you don't want anything else &amp; there is nothing better nor comparable) that will allow the new connection lines to install easily.

Happy shopping &amp; try to choose 2 or 3 faucets for the plumber to readily allocate if they obtain them.
