Advice on Replacing Rusted Bath Undermount Style Sink

mdonovan · 02-13-2010, 10:31 AM

Hello All

I have a 30 year old 16" round undermount style bathroom sink that is rusting thru the basin from below. There's no help, it's time for a new sink

Here's my problem

My style sink seems to be out of production. I wanted to use the same style / type for easier replacement. The hole in the marble counter top is 16.5" diameter and the sink is attached from underneath with 4 clips.

Here is the hard part, the 3 holes for the sink fixture are part of the sink itself, not cut into the counter top. The 3 sink holes seem to be the standard 4" spacing for a fixture attachment.

I have looked on line at under mount sinks and don't see any with my style. I looked at Home Depot & Lowes in person with out luck. When I described my sink to the kid at Home Depot he said his grandmother has a sink like that at her place....thanks kid....

Problem # 2

Using a drop in style sink instead of a under mount style. None of the drop in style sinks I have seen so far will fit in a 16.5" round hole. The counter top is marble and I have never cut marble before

My first post, can I attach pictures here as well ?

a pic would be great

Yeah, please load up some pictures.

This is my fist time here, so I'm learning as I go. It wasn't easy to get the pictures thru.

As you can see, the faucet fixture is part of the under mount sink style and not drilled into the marble counter top

The 3 holes for the fixture appear to be 4" apart type

Has anybody seen this type sink available now ? All the under mount I can find do not include the fixture holes

The size of the hole needed for a newer drop in type sink seems to be bigger than my 16.5" cutout. I've never cut a marble counter top, and especially a round cut at that

have you tried talking to a plumbing supply house to see if they inventory something like this? that sink doesnt look like it was made for that hole either, looks like a dropin mounted under counter style

I'm not a plumber, but it almost looks to me like it is a regular top mount sink undermounted.

Is part of those little soap holders on either side of the taps under the counter?

Great job on the photos by the way.

As you can see from the bottom side of the sink, it seems to be a under mount style ( round sink ) with 4 clips

The usual plumbing lines are attached, no problem there

I have not been to a plumbing supply store yet, I started with Home Depot / Lowe's / etc...

The sink is rusting from the bottom side pretty good.

Has anybody seen a sink like this before ( see above pic's ) that was not in your grandmother's house ? The kid at HD mentioned this to me

Can't tell from website but might this drop-in work from HD:

I would think you could find a drop-in (metal) one that you could undermount like the current one; might take a bit of shopping with a tape measure.

Yeah, I saw the one you mentioned at HD

It's a top mount style and I need a to cut a bigger hole in the marble countertop for it to fit correctly ( including the 3 holes for the water and stopper ) I've never cut marble, let alone try for a round hole

I may need to go pro on this one.

THX again Bob

Mdonovan:

I am experiencing exactly what you are describing! I've gone one step further and looked into replacing the countertop with built in basin, but my counter is not a standard size at 55" wide, 22" deep. I'd love to hear what you figured out. I have the same sink, same rusted out issue. In a pinch!
