How to Choose the Right Medicine Cabinet Size
A complete guide to measuring, sizing, and selecting the perfect medicine cabinet for your bathroom — with size ranges from 14" to 64".
Choosing the right medicine cabinet size is the single most important decision in your purchase. Too small and you waste storage potential. Too large and it overpowers the vanity or won't fit the wall space. This guide walks you through measuring, size categories, and product matching — and introduces all 8 medicine cabinet models with complete specs so you can find your perfect fit.
1 Measure Your Available Wall Space
Before browsing any product, measure the width and height of the wall area where the cabinet will be installed. Account for:
- Width: Measure between any adjacent obstacles (light switches, towel bars, toilets, adjacent walls). The cabinet must be at least 1" narrower than this gap.
- Height: Measure from the vanity countertop up to any obstruction (window, light fixture, ceiling). Standard mounting height is 60" from floor to mirror center.
- Depth: For surface mount, the cabinet projects 5–6" from the wall. For recessed mount, the wall cavity must be deep enough (typically 3.5" for standard 2×4 walls).
Pro tip: For surface mount, your cabinet width should be 2–4" narrower than your vanity width. For example, a 36" vanity pairs best with a 30–32" wide cabinet.
2 Understand the Size Categories
Medicine cabinets fall into three width categories. Here's how they map to bathroom types:
≤19″ Small
14"–16" wideBest for powder rooms, half-baths, RV bathrooms, and tight spaces. Fits small vanities (24" or less). Available in 14×18, 16×20, 16×24 sizes.

Sizing FAQ
What is the most common medicine cabinet size?
The most common sizes are 24×30 and 30×26, fitting standard 30–36 inch vanities. For LED models, 30×32 and 36×32 are the top sellers.
What size cabinet do I need for a 36" vanity?
For a 36" vanity, choose a cabinet 30–32" wide. The 30×32 MC002 or MC001, 30×26 MC010, or 36×24 MC011 are all excellent fits. This leaves 2–3" of vanity on each side.
What is the smallest medicine cabinet available?
The MC011 Recessed in 14×18 is the smallest — just 14" wide and 18" tall. The 16×20 and 16×24 sizes are also available across MC002, MC005, MC006, MC010, and MC011.
What is the largest medicine cabinet available?
The MC011 Recessed in 64×32 is the largest — a full 64" wide and 32" tall, spanning double vanities up to 72". The MC005 Beveled (60×30) and MC006 SS Framed (60×32) are also available in large formats.
Can I use a round medicine cabinet in a standard vanity?
Yes. The Round LED (24–30" diameter) and Round Non-LED (20" diameter) work well above 30–36" vanities. Mount centered on the vanity for a balanced look.
Should I choose one large cabinet or two smaller ones for a double vanity?
Two individual cabinets (one centered over each sink) look more intentional and provide personal storage per user. A single large cabinet (48–64" wide) offers more unified storage but can feel less balanced with widely spaced sinks.
How much space should I leave between the cabinet and the countertop?
For surface mount, 4–6" above the countertop is standard. For recessed mount, the bottom of the cabinet can sit at countertop level since it's flush with the wall. In both cases, the mirror center should be at roughly 60" from the floor.
What if my wall width is between standard cabinet sizes?
Choose the next size down. A cabinet that's 1–2" narrower than the available space is preferable to one that's too tight. You can fill the gap with trim or caulk for a finished look.
Which Tetote model has the most size options?
The MC011 Recessed offers 19 sizes — more than any other model by a wide margin, including uncommon sizes like 12×36 and 64×32. For LED models, MC001 and MC002 each offer 9 sizes.
Do Tetote medicine cabinets come with a warranty?
Yes. All Tetote medicine cabinets come with a 3-year warranty and lifetime customer support. Returnless replacement for damaged or missing parts, 60-day returns, and free shipping from 16 US warehouses (3–5 day delivery).
