In nearly all cases, the big answer is yes — you should attach your vanity to the wall. What's more, the vanity should be flush against the wall, with no space between the back and the wall itself. The reason for this is to hide and protect your plumbing.
Step 2: Measure the Width of Your Space
To accommodate a single-sink vanity, you'll need at least 18" of width available. For a double-sink vanity, you'll need at least 48" of width available. Remember that the vanity top will typically add ½ to 1" on either side of the vanity width.
Discharge/drain hole from back wall (vertical): Zero distance (drain located at floor height) Fixture (side to side buffer): 15-18 inches clearance from finished sidewall, sink or another object. Fixture (front buffer): 21 inches minimum clearance, 30 inches recommended.
The typical comfort height for the positioning of a floating bathroom vanity unit can be anything between 25-30 inches from the floor, or 635 to 760mm.
However, if you have a range of heights in your family, choosing an average is best. For example, technically speaking, the optimal vanity height for men is between 34 and 36 inches, and the optimal height for women is between 32 and 34 inches. The average number of 34, then, fits the bill for both men and women.
Bathroom vanity standard height ranges between 82 cm and 91 cm. There are some standardised dimensions for sinks and basins as well. Most vanity basins range from 50 cm to 58 cm, with 53 cm being the most common depth.
The correct rough-in height for sink drains to pass the inspection is between 18 and 20 inches. Standard sink drains usually start from 24 inches and stop at 28 inches, so the rough-in height should be slightly lower than this height range.
Most sink manufacturers provide a template. Position the template so it is centered on the sink cabinet and is at least 1 1/2 inches back from the countertop's front edge. If your countertop is deeper than 24 inches, place it farther back, but not more than 4 inches.
Your drain's position will affect a number of things, including under-sink storage, faucet noise, and how easy it is to stack dishes. Here's what you need to know about a centered drain vs offset drain to help you pick the right style.
Measure the depth of the available space for bathroom vanity
A helpful tip is to open the door, mark it with a coin and take your measure from that point. If space is at a premium, try to leave a minimum of an inch or two between all of the bathroom items. Bathroom vanities typically have a depth of 18 to 22 inches.
When preparing to install the light fixtures and mirror above a bathroom vanity, the easiest way to start is with the mirror, as you want to center it on the wall. Standard spacing for a vanity mirror(s) is 5-10 inches from the vanity sink to the bottom of the mirror.
Vanities and Pedestal Sinks
Clearance in front of the vanity: 21" minimum, although 30" is recommended for a total of 51" from the wall.
Installation. Most vanity lights can be mounted with lights pointed up or down. Remember to mount the fixture with the lights pointed up for ambient lighting and pointed down for task lighting.
If a window is available, position the vanity nearby to capitalize on natural light. If you're relying on artificial light, install fixtures on either side of the mirror—this will illuminate your face more effectively than overhead lighting alone.
Lay the sink upside down on the counter. Align the mark on the sink with the one on the counter. Adjust the sink to leave 1½ inches between its back edge and the backsplash. Be sure sink is parallel with the counter's edge.
Guidelines recommend including at least a 24” wide landing area to one side of the sink, and at least an 18” wide landing area on the other side.
Standard countertop overhang is 1 ½ inches.
Keep in mind that this is 1 ½ inches over the front edge of the base cabinet. While some countertops may have different overhang measurements, this is the number that is seen as standard for homes. While 1 ½ inches is the most common, it's far from mandatory.
The bathroom sink's water lines are roughed-in 3 inches above the drain. Measure 21 inches (approximately) above the finished floor. The hot line and cold line are spaced 8 inches apart (from left to right). From the center of the drain, measure 4 inches to the left and 4 inches to the right.
Cold water should always be on the right side of the faucet and hot on the left. This is an industry standard throughout North America and applies to single lever as well as dual faucets. When indoor plumbing was first introduced, there was one option that came out of the hand pump: cold water.
09/28/2021. New construction plumbing generally fits into two categories, rough in plumbing and finish plumbing. Rough-in plumbing is the process of installing vents, sewers, connections and waterlines. During the finish plumbing phase, plumbers will finish installations and connections to get the home ready for use.
Bathroom base cabinets and vanities are typically lower than kitchen countertops because they are designed for tasks done seated or when bending at the waist, such as applying makeup or shaving.
The best locations to install electric outlets in the bathroom are on the wall above the countertop, at a height of about 36 inches from the floor, near the vanity mirror, and away from the shower or bathtub.
Typically, it is best if the mirror is centered over the sink. If you have two sinks and are putting up two mirrors, they should each be centered over their respective sink. You'll also want to make sure that you leave enough room on either side of the mirror so it's hanging evenly.
