The bathroom vanity unit is more than just a sink cabinet. It's the focal point of the room, the primary storage solution, and a major indicator of your bathroom's overall style. Choosing the right one is a balance of form and function — and getting it right makes a significant difference to how your bathroom looks and feels every day.
Step 1: Measure Your Space First
Getting the size wrong is the costliest mistake you can make. Before browsing styles, take accurate measurements of your bathroom.
- Width: Measure the wall space where the vanity will sit. Leave at least 21–24 inches of clearance on each side of the toilet and ensure the door can swing open freely. Standard widths are 24", 30", 36", 48", and 60".
- Depth (projection): Standard depth is 21–22 inches. Ensure it doesn’t obstruct walkways — wall-mounted vanities can offer a slimmer profile where space is tight.
- Height: The traditional 32-inch standard is giving way to comfort-height vanities (34–36 inches), which reduce back strain and feel more like kitchen worktop height.
Step 2: Choose Your Vanity Configuration
The way your vanity is mounted affects both the look of the room and the practicality of daily use.
Freestanding Vanity
Classic in appearance, with generous storage options. Ideal for larger bathrooms and traditional or transitional interior styles. Easy to install and replace.
Wall-Mounted (Floating) Vanity
Creates a light, open feel, makes cleaning floors effortless, and delivers a supremely modern look. Requires sturdy wall mounting — always check your wall construction before purchasing.
Floor-Mounted Cabinet
The most common configuration, offering maximum storage and stability. Modern Splash offers a wide range of floor-mounted designs with contemporary flair — from clean-lined gloss finishes to warm wood-effect options.
Step 3: Maximise Storage and Functionality
Think carefully about your daily routine before deciding on internal configuration.
- Drawers vs. doors: Deep drawers are excellent for organised storage of hair dryers, products, and folded towels. Doors with shelves are better suited to taller items like cleaning products.
- Internal organisation: Look for features like adjustable dividers, soft-close mechanisms, and tilt-out sink front trays for sponges and cloths.
- Sink choices: Undermount sinks create a seamless countertop for easy cleaning. Vessel sinks make a bold style statement and work particularly well with wall-mounted vanities.
Step 4: Material Matters — Durability and Aesthetics
- Cabinet construction: Look for solid wood frames, plywood, or high-density MDF with a waterproof laminate or paint finish. Avoid particleboard in wet areas — it deteriorates quickly with moisture exposure.
- Countertop: Quartz is a top choice for its durability, non-porous surface, and wide range of designs. Ceramic is cost-effective and highly durable.
- Finish: Lacquered finishes in matte or gloss provide a sleek, wipeable surface. Wood veneers and wood-effect finishes offer natural warmth. All Modern Splash vanity units use quality materials built for the humid bathroom environment.
Step 5: Choose Your Style
Your vanity should complement your overall bathroom design theme. Here are the most popular styles:
- Modern/Contemporary: Clean lines, flat-panel doors, neutral colours (white, grey, black), and minimalist hardware. The most popular choice for new-build and recently renovated bathrooms.
- Transitional: A blend of traditional and modern — perhaps shaker-style doors in a contemporary colour palette. Versatile and timeless.
- Industrial: Raw materials, metal accents, and a utilitarian aesthetic. Works well with exposed brick, concrete, and dark colour schemes.
Frequently Asked Questions
What size bathroom vanity do I need?
The right size depends on your available wall space and bathroom layout. As a general rule, leave at least 21 inches of clearance beside the toilet and ensure the vanity depth doesn’t obstruct walkways. For a single-basin vanity, 600–900mm wide is the most common range for UK bathrooms.
Are wall-mounted vanities better than floor-standing ones?
Both have advantages. Wall-mounted vanities create a more open, spacious feel and make floor cleaning easier — but require solid wall fixings. Floor-standing vanities offer more storage and are easier to install, making them the more practical choice for most bathrooms.
What's the best material for a bathroom vanity unit?
Look for moisture-resistant MDF or solid wood with a waterproof finish. Avoid standard particleboard in wet environments. Quartz or ceramic countertops are the most durable and hygienic options for the basin surround.
Can I install a bathroom vanity myself?
Floor-standing vanities are generally straightforward to install with basic DIY skills. Wall-mounted vanities require more care — you’ll need to locate wall studs or use appropriate fixings for your wall type. Any plumbing connections should be carried out by a qualified plumber.
