Allen + Roth Bathroom Vanities

What Size Bathroom Vanity Do I Need

The range runs from single-sink cabinets up to double vanities. Vanity widths are largely standardised across the market, so the numbers below are the ones you will keep meeting.

• 24 and 30 inch: powder rooms and tight walls. One bowl, and little counter beside it.
• 36 inch: the usual middle ground. Room for a drawer bank beside the bowl without dominating a small bathroom.
• 48 inch: a generous single sink, with counter either side of the bowl.
• 60 inch: the width at which two sinks stop feeling cramped.

Single versus double is a plumbing question more than a width one. A second bowl needs its own trap and supply pair, eating the cabinet interior where drawers would go and usually meaning new rough-in work. Under 60 inches, one bowl with usable counter beats two with none.

Vanities With Tops vs Vanities Without Tops

Lowe’s lists vanities with tops and vanities without tops as separate categories. Check which one you are looking at before you add anything to the cart.

• With a top: one product, one warranty document.
• Without a top: a cabinet only. You buy the surface separately, and it carries its own warranty from whichever company fabricates it.

Buying without a top lets you choose the stone and the bowl style, at the cost of two purchases and two sets of paperwork. Read the listing rather than assuming the photo shows what ships.

How to Measure for a Bathroom Vanity

Take every number before you shop, not after delivery. The plumbing points are the two people skip.

• Wall to wall at floor level and again at counter height. Walls are rarely square, and the narrower number is the one that matters.
• Depth from the finished wall into the room, checked against the listing rather than an assumed standard.
• Plumbing rough-in: floor to the centre of the drain stub, and side wall to the centre of the drain. Supply valves the same way.
• Door swing. Open the bathroom door fully, mark where the leading edge lands, and check the vanity front and an open drawer clear it.
• The path in: doorways, stair turns, the landing. A 60 inch cabinet arrives in one piece.
• If the top is a separate purchase, size it to the cabinet, not to the wall.

What to Check Before You Buy

• Whether a faucet is included, and how many holes the top is drilled for. A single-hole faucet will not fill a three-hole top without a deck plate.
• How the drawers are built. Pull one fully out in store: how the box corners are joined, whether the runners are soft-close, and whether it is cut around the trap.
• Who fabricates the top, if it is quartz or solid surface. Sage Surfaces publishes a non-transferable Lifetime Limited Warranty and a separate 30 Year Transferable Warranty for a+r Quartz, and Dal-Tile publishes a Residential Lifetime Warranty. Each runs through that company’s authorised fabricator.
• Seams, on a double vanity. The Sage quartz warranty does not cover seam performance. The Sage solid surface warranty covers seam performance but not its appearance.
• The use and care sheet in the carton. Damage from improper soaps or cleaning agents that etch or stain a stone top is excluded, so check what the sheet permits before the first clean.
• Keep the receipt. Proof of purchase is what a claim runs on, and nothing asks you to register.

How to Install a Bathroom Vanity Yourself

A vanity swap is within reach for most people, but the warranty excludes installation, so anything you damage is yours.

• Shut the supplies off and drain the lines first. Old shut-off valves often weep once turned, so have replacements to hand.
• The back panel usually needs cutting for the drain and supplies. Transfer the reference points you took off the wall, and cut generous: nothing shows once the top is on.
• Floors slope. Shim the cabinet level front to back as well as side to side, then fix into studs where you can and rated hollow wall anchors where you cannot.
• Fit the faucet and drain to the top on the floor. Doing it afterwards means lying inside the cabinet.
• Caulk where the cabinet meets an out-of-square wall, and silicone the back edge of the top.

Common Vanity Buying Mistakes

• Buying to the wall measurement and forgetting the door swing.
• Assuming the top and faucet are in the box because they are in the photo.
• Cleaning a stone top with a general bathroom spray before reading the care sheet.
• Throwing the receipt away.

What Owners Say About Allen + Roth Vanities

The recurring criticism is after-sale support rather than what arrives in the box: parts for discontinued items, and short or awkward warranty terms.

Ranges get retired and finishes reworked, so if you are fitting two bathrooms, buy both units now rather than matching later. See what happens when a range is discontinued before counting on a top-up.

If you need a part for an older vanity, start with the parts line on 1-866-439-9800, or read how to go about tracking down replacement parts.
