Installing new trim on “Standard Companion”

Re-trimming (replacing the handles and escutcheons) on American Standard China Shelfback sinks from the 1930’s through the fifties (like the above examples) used to be almost impossible due to a lack of available parts.  Here at Bathroom Machineries, we’ve discovered a simple way to make your sink look new again.  It will require a bit of homework on your part first, as Standard used two different stems in identical looking sinks. 

Note!  Only do the following if you want to replace the trim on your sink.  If the trim is good and it’s simply leaking out of the spout, refer back to the stems page.

Remove the existing stems from your sink after shutting off the water.  Note the length of the large fine thread on your bonnet nut.  You’ll have two options, either the thread will be 5/16” long or it will be 1/2” long.  Once you know the length, you can order our re-trim kits below.

If your bonnet nut is 5/16” long, (left side of above photo) then you will want to order the
 86-061HM kit.  If the bonnet is 1/2” long, (right side of above photo) you will want to order the 86-081HM kit.

Both kits are supplied with the following;
Two stems
Two escutcheons
Two escutcheon nipples
One pair handles with buttons

Note; the escutcheons will be of a similar design to the originals, but they will not be exactly the same.  They are slightly wider and taller than the originals.  See photo below.

86-061HM Kit, for sinks with 5/16” bonnet nut thread length $173.00 addtocart5

86-081HM Kit, for sinks with 1/2” bonnet nut thread length $173.00 addtocart5

Note, many sinks of this style were supplied with lever handles.  If using this kit, the sink is converted to cross handles.  A lever handle version is not available.

Chrome only, no other finishes available.

Trip levers are not made anymore, but often we can replate the existing lever.  Call or e-mail for details.

Original style drains aren’t made anymore either, but they can be replaced with our 79-P85C pop-up assembly.  You will need to save the drain linkage that connected the lever to the drain from the original assembly, as this is a brand -specific, unobtainable part.


1950’s “Standard” Pop-up Assembly
This drain assembly fits both the above Standard Shelfback sink and many other Standard sinks from the 1930’s through the early 1960’s.  These are a bit larger than the pop-up assemblies of today.  Restored original, with a fresh coating of chrome, and it’s supplied with your choice of either a 1 1/4” or 1 1/2” diameter tailpiece.  (please indicate this choice in “comments” field during checkout)  Note, this assembly does NOT come with any linkage parts for the shelfback sinks.  Limited supply!
OF15128 Standard Pop-up. SOLD OUT

We are constantly looking for these drains, but haven’t found any as of late.  We do not know when we will find more, and we may never find enough to make these available again.

Late 1930’s through 1960’s “Standard” Drain top
This is just the top of the above drain.  We have not been able to find any of the above drains to restore, so we are going to make them.  This is one of the two parts that get cut off when someone tries to repair the above drain.  The reason?  Standard made the below nut out of Zinc, and one Zinc gets wet, it welds itself to this part.  They are nearly impossible to get apart when servicing these sinks.  Not anymore!  Ours are made of Chrome plated brass, so the sink will last for many more years.  The top is 2 3/4” tall, and the flange is 2 1/8”.  Yes, the stoppers do fit.  Basin washer set sold separately, see below.

Late 1930’s through 1960’s Standard Lavy drain locknut
This is the nut that Standard made of zinc.  Again, this just wasn’t a good idea.  Ours is chrome plated brass, and fits the above drain.  Sold less 51-WA155 washer set, this locknut measures 1 15/16” across the flats, and stands 7/8” tall.  Why replace that great old sink with something from China?  Fix it today!

1930’s to 1960’s “Standard” Pop-up Drain Stopper
Yes!  We found it!  This is a reproduction of the stopper for the above Standard Lavatory drain that was in use from the 1930’s to the mid 1960’s.  Chrome only, it measures 5 1/4” long and the top is 1 3/8”.  Fix your drain today!

STD lever seal

1960’s “Standard” drain lever seal
This is the seal for 1960’s and early 1970’s Standard brand pop-up assemblies that use the rounded knurled nut.  This seat will not work on pop-ups with the hex nut shaped cap over the lever.  Sold by the each.  O.D. of seal is 1 1/16”.  Click on photo for larger view

1930’s - 1960’s Mack Basin and friction washer set
This is the washer set used between the porcelain and the metal nut on almost all Standard brand lavatory pop-up assemblies made between the mid 1930’s up to the mid 1960’s.  ID of basin washer is just under 1 7/16”.
