Not that I am remodeling, or anything that ambitious, but I have some advice nonetheless.
When you remodel say a bathroom, and there are two sinks (his/hers, very common), don’t buy just two sets of fixtures. Buy a spare.
This is so that in 5/7/10 years when one dies a miserable death and can’t be resuscetated with part kits, you will not be pulling your hair out looking at fixtures that DO NOT MATCH.
(As you may have surmised, one of ours has died, and Delta has decided to no longer manufacture the style anymore. So I get to replace two sets of fixtures, and destroy my back doing it…)
