Bought a display vanity from a cabinet mfg. that had never been plumbed. The design has a deep sink installed within a 18" tall by 24" deep cabinet. There is only 6" between the bottom (hole) of the sink and the cabinet floor. I can't find a ptrap / tailpiece fitting what will fit within the 6" clearance shown in the attached pictures.

The area below the 18x24 cabinet is open and a ptrap hanging in that area would detract from "the look".

Any ideas?

Sorry, did not attach the picture.

Hi Tluttre

Where is the waste pipe from the wall? At what height/relation is that to your cabinet... that will tell us how we can help you here... ;)

With the sink that low, you will have trouble getting any drain. You may find that the wall piping is above the sink base and water will not flow from the sink. You could possibly use an S trap with a "T" and an AAV, similar to what they use in log homes where water drains through the floor. S traps are not code accepted but can be modified with an AAV.

Mark,

The wall waste pipe will need to be moved because the sink is about 2 feet to the left of the original sink location. So, I can plumb it at any height / relation to the new sink that works.

Thanks for your quick response.

Actually, looking at this, if you get a pop-up assembly (you called it a tailpiece fitting) and you cut the tailpiece so it is about an inch long, a regular ptrap with an 1.5" PVC x 1.25" compression trap adapter (also called a desanco fitting) should work here. They also sell a STREET desanco fitting (cements directly into the trap)... adds another 1" to help, if needed.

I would dry fit everything... cut the tailpiece... and then take the measure of the setup so you can decide EXACTLY where to bring your drain pipe into the cabinet.

I'm pretty sure all this will work with standard fittings.

Let me know what you think, OK?

It appears to be a floating ( wall mounted ) cabinet. Correct ? If so, you can also drill 1 1/2" hole and run pipe through it. Use nice, chrome, metal P-Trap. Milo

Hey Milo..

Do they still allow a compression fitting AFTER the trap in California? Just curious is all! In Mass, you can't use the old-fashioned chrome traps with a compression fitting (trap adapter) after the trap (been that way for a long time). Do they still allow in Cali. Let me know, OK?

Mark,

Looks like that will be a good option. Thanks for the advice.
