How To Rough In A Double Sink Vanity

Surely, you've come across them before. Even if you don't have one, you may have grown up in a household where you did. Double sink vanity, a double sink vanity, is a luxury no matter how many people live in the house.

It was a necessity for a family of seven children, for example, who were all in school at the same time. Otherwise, they would have been stranded without transportation.

A double sink vanity has two sinks, although it does not necessary have two complete sets of plumbing requirements. Tee and 90-degree elbow adapters can be used to connect supply and drain pipes in a way that allows them to perform both functions.

However, as with any plumbing project, you must first check with your local authorities and meet with the plumbing inspector to go through your plans. With a fast conversation with the inspector, you can avoid having to tear something out and start over from scratch.

Let's take a closer look at the procedure.

What Is Rough In Plumbing?

A plumbing rough in is the process of drilling the holes in framing studs and flooring through which all water supply and drain pipes will travel, both up and down. Afterwards, all of the plumbing fixtures' pipes are connected either to or from the plumbing fixture.

For example, "rough in" is used to describe a section of wall where the pipes will terminate, which is where the vanity cabinet doors will be installed. They have not yet been outfitted with a sink, faucet, or any other appliance. They're not done yet.

As with a single sink vanity, all of the piping will be tucked away under the sink and out of sight. A large enough vanity can contain the plumbing for two sinks, including the fittings, valves and elbows, as well as the pipes and tubing.

What You Should Know About Double Sinks and Plumbing

The distance between the two sinks in a double sink design should be at least 30 inches, but ideally closer to 36 inches. If you're going to be sleeping with someone else, make sure you have enough room to move around comfortably.

This provides ample space for the plumbing beneath the sinks to supply and drain water to and from each sink.

There are a wide variety of materials and styles to choose from when it comes to bathrooms. A single vanity top with a double sink layout is common, removing the need to calculate the distance between the sinks.

Among your choices for materials:

  • Ceramics are tough, scratch- and chip-resistant surfaces.
  • Porcelain is a strong, long-lasting material that also has a delicate appearance.
  • Granite, marble, sandstone, and onyx are examples of porous stones that require specific care to maintain their beauty as works of art.
  • Even though it's uninspiring in comparison, stainless steel is stain and odor resistant.
  • Natural materials such as teak or bamboo
  • Resin, long-lasting, and simple to maintain.

A double sink vanity adds a splash of color, style, and personality to your bathroom.

Plumbing Needs

To keep waste water from escaping, every sink has a drain pipe with a trap built in. This is a universal sink plumbing need.

In order to keep sewage vapors from escaping into the bathroom, a seal is needed. A trap of this type is found in every drain pipe and every drain fixture.

The venting of a sink is also necessary for proper operation. A vent helps maintain a continuous flow of water through a drain pipe by distributing the water's pressure evenly.

However, all bathroom sinks, whether single or double, share these requirements. However, if local plumbing regulations allow for a common drain, there is no additional cost.

Benefits

In addition, they might help to make your bathroom life a lot more convenient.
