When it comes to plumbing for a double vanity, the rough-in is one of the most important aspects. This is because the rough-in will determine where your pipes will be located and how they will be connected. If you’re not familiar with rough-ins, they are simply the measurements that are taken from the wall to the center of each drain.
Installing a double vanity in your bathroom is a great way to add style and function. But before you start shopping for vanities, you need to do some planning to make sure everything will fit and work correctly. That includes figuring out the plumbing rough-in.
The most important measurement when it comes to the plumbing rough-in for a double vanity is the distance between the two centers of the drain pipes. That needs to be at least 21 inches, but more space is better. You also need to consider the location of water supply lines and make sure there’s enough room for both vanities to have their own supplies.
Once you have all of that figured out, you can start shopping for vanities. There are lots of great options out there, so take your time and find something that fits your style and budget. With a little planning, you can easily install a beautiful new double vanity in your bathroom!
Double Bathroom Sink – Two Different Rough Plumbing Drain Methods
Can 2 Sinks Share the Same Drain?
There are a few different ways that two sinks can share the same drain. The first way is to have a Y-shaped fitting on the drain line. This allows each sink to have its own trap, which keeps sewer gases from coming up through the drains.
The other way is to have a single trap with two vents, one for each sink. This setup requires more maintenance because the traps need to be cleaned out more often.
How Should a Double Sink Drain Be Plumbed?
Most double sink drains are plumbed with a tee fitting. The drain from each sink is connected to the tee, and then a pipe runs from the tee to the trap. The trap is usually located in the center of the two sinks.
What is the Plumbing Rough-In Height for a Bathroom Vanity?
There is no definitive answer to this question as the rough-in height for a bathroom vanity can vary depending on the specific installation. However, a good rule of thumb is to make sure that the rough-in height is at least 18 inches above the finished floor. This will ensure that there is enough clearance for the plumbing fixtures and any other items that may be installed in the vanity.
Does a Double Sink Vanity Need Two P Traps?
No, a double sink vanity does not need two P traps. The P trap is the U-shaped pipe that is located under the sink and connects to the drain. This trap holds water in order to prevent sewer gases from entering the home through the drain.
Each sink will have its own P trap.

Plumbing Code for Double Vanity
There are many factors to consider when choosing plumbing fixtures for your home, but one of the most important is code. In order to ensure that your home is up to code, it’s important to choose plumbing fixtures that comply with the latest codes and regulations. When it comes to double vanities, there are a few key things to keep in mind in order to make sure you’re in compliance.
First and foremost, double vanities must be connected to two separate water lines. This means that each sink must have its own supply line and drain line. Additionally, each sink must have its own shut-off valve so that you can control the flow of water to each individual sink.
This is an important safety measure in case of a leak or other issue with one of the sinks.
Another key consideration is venting. Double vanities need proper ventilation in order to function properly and avoid issues like mold and mildew.
The best way to achieve this is by installing a ventilated pipe system that runs from each sink drain up through the roof. This will allow any moisture or odors to be properly vented out of the home, keeping your bathroom clean and fresh smelling.
Finally, when it comes to actually installing your double vanity, there are a few things you need to keep in mind.
First, both sinks should be level with each other as well as with the countertop surface they’re sitting on top of. Additionally, you’ll want to make sure that there’s enough clearance around each sink so that people can comfortably move around them without bumping into anything sharp or getting too close for comfort. By following these simple tips, you can ensure that your new double vanity is both stylish and compliant with all applicable codes and regulations!

Can a Double Vanity Share a Drain
If you’re considering installing a double vanity in your bathroom, you may be wondering if you can share a drain between the two sinks. The answer is yes, you can! Here’s how it works:
The main drain for your bathroom will likely be located in the center of the room, underneath the floor. From here, smaller drains branch off to each sink and toilet in the room. When you install a double vanity, each sink will have its own trap (a U-shaped pipe that prevents sewage gases from entering your home), but they can share a common drain line.
There are a few things to keep in mind if you’re planning on sharing a drain between your double vanity sinks. First, make sure that both sinks are properly vented so that water can flow freely and there’s no risk of backups or clogs. Second, it’s important to use high-quality plumbing fixtures and materials to minimize the risk of leaks.
And finally, be sure to have a professional plumber install your double vanity to ensure everything is done correctly!
Conclusion
When it comes to plumbing a double vanity, the rough in is one of the most important aspects. This is because the rough in determines where the pipes will be located and how they will be routed. If you are not careful, you could end up with a messy installation that is difficult to fix.
The first step is to mark out the location of the drain lines on the floor. You can do this by using a tape measure and marking the center point between the two drains. Next, use a stud finder to locate the studs in your wall so that you know where to drill holes for your supply lines.
Once you have all of your supplies ready, it’s time to start assembling your double vanity plumbing rough in.
Start by attaching your P-trap to the drain line coming from the left sink. Then, connect your supply lines to each of the shut-off valves underneath each sink.
Finally, screw in your traps and supply lines before connecting them to the main drain line. With everything connected, turn on your water supply and check for leaks.
