How to Choose a Bathroom Vanity
The Complete Buying Guide
A shower is the fixture you use every single day, and the one with the most moving parts to get right. Unlike a toilet or a tub, you don't buy a shower in one box — you assemble it from a base, a door or enclosure, a shower head and valve, and the drains and storage that finish it. This guide walks through those choices in the order that matters, so every piece fits your space, works together, and shares one clean finish.
Measure your space and confirm the plumbing lines up. Decide single or double sink based on width — 48 inches is the minimum for two sinks, and 60 inches or more is more comfortable. Choose freestanding for flexibility or wall-mount for a lighter, modern look. Pick a cabinet finish that coordinates with the room, confirm whether the top and sink are included, and match the faucet drilling. Then tie it together with a mirror and hardware in the same finish family.
Start here:
the 6 decisions
Every well-chosen vanity answers these questions, roughly in this order.
- Step 1
Will it fit — and does the plumbing line up?
Measure width, depth, height, and clearances.
- Step 2
Single or double sink — and how much storage?
Match the configuration to your space and routine.
- Step 3
Freestanding or wall-mounted?
The biggest driver of look and installation.
- Step 4
What cabinet material and finish?
Flush technology, GPF, and single vs. dual flush.
- Step 5
What countertop and sink?
Included top or separate; undermount, integrated, or vessel.
- Step 6
How does it coordinate?
Faucet, mirror, and hardware finish.
Measure your space and plan the plumbing
Before you fall for a finish, make sure the vanity fits and the plumbing works. A few measurements prevent a costly return.

18–72" vanity widths
Width, depth, and height
Swiss Madison vanities run from a compact 18 inches up to 72 inches for a double. Standard depth is about 18 to 21 inches; if your bathroom is tight, a slim vanity around 12 to 15 inches deep keeps the walkway clear. Standard vanity height is roughly 32 inches, while a taller “comfort height” of about 34 to 36 inches is easier on the back — pick based on who uses the room.
-
15"+ sink center to side wall
Clearances
Leave room to live around the vanity. As a general guide, plan for about 15 inches from the sink center to a side wall (20 inches feels roomier) and at least 21 inches of open floor in front. Tight powder room? Compact, corner, and wall-hung sinks are designed for exactly those spaces. If you're moving plumbing, check local requirements with your contractor or building department.
-
3 faucet drillings
Plumbing and faucet
Note where your water supply and drain come out of the wall or floor. Freestanding vanities hide standard floor and wall plumbing easily; wall-mounted vanities need the supply and drain to come out of the wall behind the cabinet, so a floor drain may need to be moved. Finally, match the faucet drilling: a single-hole faucet, a 4-inch centerset, or an 8-inch widespread each need a top drilled to suit.
If you're keeping your existing faucet, confirm its hole configuration before choosing a vanity top — mismatched drilling is one of the most common and avoidable vanity headaches.
Choose single or double — and your storage
Width decides this. Swiss Madison offers double-sink vanities in collections such as Classe, Cascade, and Pierre, with single-sink options across the range, so you can match the layout to the room.
| Configuration | Width | Best for | Sinks |
|---|---|---|---|
| Single sink | Below about 48 inches. | The most usable counter and storage. | One |
| Double sink | 48 inches and above; 60 inches or more is more comfortable. | A shared primary bath where two people get ready at once. | Two |
Storage style. Drawers — best for everyday items you want to see and reach; soft-close drawers feel the most considered. Doors and shelves — best for taller items and hiding cleaning supplies behind a clean front. Open shelf — a lighter, more architectural look, as on the metal-frame Pierre collection; great for folded towels and baskets. Also check the sink placement: a center sink splits storage evenly, while an offset sink frees up a run of usable counter to one side.
Freestanding or wall-mounted
Mounting type is the biggest driver of both look and installation. Compare freestanding vanities and wall-mount vanities.
| Type | What it is | Best for | Install effort |
|---|---|---|---|
| Freestanding | A cabinet that sits on the floor, finished on the visible sides. | Maximum storage, easy install, a warm furniture-like look. | |
| Wall-mounted (floating) | Mounts to the wall with open floor space beneath. | A light, modern look; easier floor cleaning; small baths. |
Which one fits your bath
Choose freestanding for the most storage and the simplest installation — it hides plumbing and reads like a piece of furniture. Choose wall-mounted when you want a lighter, contemporary look, easier floor cleaning, or a little more visual space in a small bathroom.
Plan the wall. Wall-mounted units call for solid blocking in the wall to carry the weight, so factor that into the install.
Choose the cabinet material and finish
Material
A bathroom is humid, so the cabinet has to handle moisture and still look good for years. Look for solid wood or quality engineered wood with a sealed, moisture-resistant finish — the combination that survives a steamy bathroom without warping.
Finish
Finish is where the vanity meets your style. Our core palette is built on wood-grain finishes, from light, natural tones to deep, dramatic ones, and select collections extend into solid colors for a crisper, more contemporary look.
Finish family
Light, natural wood grains bring warmth and a timeless, organic feel, and keep a smaller room feeling open.

Small or windowless bath — a lighter finish (White Oak, White, Natural Oak) keeps the room feeling open
Larger or well-lit bath — a deeper tone (Black Oak, Walnut) adds warmth and a grounded, high-end feel
Most Swiss Madison vanity cabinets are built from engineered wood (MDF) with sealed finishes — moisture-resistant construction made to hold its shape in a steamy bathroom.
Choose the countertop and sink
The top is the surface you use every day, so choose it for how easily it lives as much as for how it looks.
Is the top included?
First, confirm what comes with the vanity. Some Swiss Madison vanities include a coordinated top and sink; others are sold as a cabinet with the vanity top chosen separately, which lets you pick the exact material and sink style. Knowing this up front avoids a surprise at checkout — and lets you budget the top into the project.
Countertop material
Ceramic and engineered stone tops resist water and wipe clean easily, which is what you want on a daily-use vanity. If you're choosing a top separately, weigh look against upkeep: engineered quartz is hard-wearing and low-maintenance, while natural marble is beautiful but needs sealing and gentler care.
Sink type
Undermount — mounted below the top for a seamless edge that wipes clean in one motion. Integrated — the sink and top are one molded piece, so there's no seam at all. Vessel — a basin that sits on top of the counter for a statement look; pair it with a taller vessel faucet.
Coordinate the look
The last decision is how the vanity pulls the room together. Match the faucet and hardware finish — and carry that finish to the mirror frame, lighting, and nearby fixtures. A Swiss Madison LED or smart mirror above the vanity finishes the wall and adds task lighting, and coordinating the faucet, drain, and cabinet pulls makes the space read as one intentional design rather than a set of separate purchases.
This is exactly where Swiss Madison is built to win: a premium, coordinated look at an attainable price. Because we design our own products and offer them direct and through major retailers, you can outfit the whole vanity wall — cabinet, top, faucet, and mirror — in one coordinated design language, without overpaying for a luxury name.
Installing your vanity
A freestanding vanity is an achievable DIY project for a confident homeowner; wall-mounted units and stone tops are heavier and often worth a pro. Either way, these steps keep it clean and solid:
Turn off the water supply and clear the old vanity before measuring twice for the new one.
Dry-fit the cabinet and check the plumbing lines up with the openings before you set it in place.
For a wall-mounted vanity, anchor into studs or solid blocking — never drywall alone — to carry the weight.
Level the cabinet front to back and side to side, shimming as needed so drawers and doors sit true.
Set the top, connect the faucet, drain, and supply lines with fresh seals, and check for leaks.
Seal the vanity-to-wall joint with a bead of silicone caulk to keep water out of the gap.
