Built-In Microwaves vs Countertop Models

Choosing between a built-in microwave and a countertop microwave isn’t just about heating food—it’s about
space, style, and budget. This guide explains how each option fits different kitchens and lifestyles so you can make a confident, future-proof choice.

In short: built-in microwaves deliver a seamless, integrated look and free up your worktop, while countertop microwaves offer
plug-and-play convenience, flexibility, and lower upfront cost. Read on to compare installation, costs, capacity, and features—with practical tips to avoid common mistakes.

What you’ll learn

How built-in and countertop models differ in installation, space use, and day-to-day practicality.
Typical costs and what impacts price (cabinetry, trim kits, electrical requirements).
Which features matter most: power (W), capacity (L), grills/convection, sensors, and smart controls.
How to match the right microwave to your kitchen layout—owner-occupied homes vs rentals.

Planning note: If you’re short on cabinetry or you rent your home, a countertop microwave avoids
alterations and still delivers excellent day-to-day convenience.

Quick win: Before you decide, measure the intended space (including door swing and ventilation clearances) and check your
power supply and worktop depth. This prevents compatibility issues later on.

What is a Built-In Microwave?

A built-in microwave is designed to be installed directly into your kitchen cabinetry or wall units. Unlike freestanding models, it becomes part of the kitchen layout, creating a seamless and integrated look. Often positioned above an oven or at eye level, they are a popular choice for modern and minimalist kitchens.

Main benefits

Saves counter space – frees up valuable worktop area for cooking and preparation.
Sleek and modern appearance – blends perfectly with other built-in appliances.
Convenient placement – often installed at eye level, reducing bending and lifting.
Higher-end features – many models include convection, grilling, or smart functions.

Limitations to consider

Higher cost – both the unit and installation are typically more expensive.
Professional fitting required – usually needs an installer or carpenter to integrate properly.
Less flexible – fixed in place, so not suitable if you move home often.
Size restrictions – cabinet dimensions dictate the microwave size you can choose.

Note: Built-in microwaves often require a trim kit for proper ventilation and a professional finish. Without it, overheating and performance issues can occur.

Tip: If you’re planning a kitchen redesign, consider placing your built-in microwave at eye level. It improves safety and makes it easier to check food without bending.

What is a Countertop Microwave?

A countertop microwave is a freestanding appliance designed to sit on your kitchen worktop. It’s the most common type of microwave because it is easy to install (just plug it in) and can be moved whenever needed, making it highly versatile and renter-friendly.

Advantage

Affordable – lowest cost option with no installation required

Advantage

Simple plug-and-play setup

Advantage

Portable – easy to move, ideal for renters or students

Limitation

Takes up counter space, reducing prep area

Limitation

Less integrated look compared to built-in models

Limitation

Cheaper versions may lack features like convection or grilling

Note: Countertop microwaves still require proper ventilation space around the sides and back. Crowding them into corners or against walls can cause overheating.

Tip: If you want the look of a built-in but prefer the flexibility of a countertop model, consider using a microwave trim kit to give it a more integrated finish.

Built-In vs Countertop Microwaves: Side-by-Side Comparison

To help you decide which type of microwave best suits your kitchen and lifestyle, here’s a clear
side-by-side comparison of the key differences between built-in microwaves
and countertop models.

Feature	Built-In Microwave	Countertop Microwave
Installation	Requires professional fitting and trim kit	No installation – plug in and use
Cost	Higher purchase price + installation fees	Lowest cost option, no extra fees
Space	Frees up valuable counter space	Takes up worktop space
Appearance	Sleek, seamless integration with cabinetry	Visible appliance, less stylish in modern kitchens
Flexibility	Fixed in place, not portable	Portable – can be moved easily
Features	Often includes advanced functions like convection, grilling, or smart controls	Basic models available, with fewer premium features
Best For	Homeowners, modern kitchens, those seeking a streamlined design	Renters, students, budget-conscious buyers

Note: While both types cook food effectively, the main differences come down to
space, design, and budget. Your choice depends on whether you prioritise flexibility or integration.

Cost Considerations

Total cost depends on the appliance price and any extras like installation, trim kits, and potential cabinetry or electrical work. Use the guide below to estimate the difference between a built-in microwave and a countertop microwave.

Cost Area	Built-In Microwave	Countertop Microwave	Notes
Appliance price	Typically higher (£250–£900+)	Lower overall (£60–£300+)	Premium features (e.g., convection, grill, sensor cooking) increase price on both types.
Trim kit / fascia	Often required (£50–£200)	Optional (only for a built-in look)	Ensures correct ventilation and a flush finish in cabinetry.
Installation	Professional fitting (£80–£200+)	None – plug in	Costs vary by region and the complexity of the cabinet aperture.
Cabinetry adjustments	Possible extra (£50–£300+)	Not required	Cutting, strengthening shelves, or adding a housing can add labour time.
Electrical work	Occasional (£0–£150+)	Rare	New spur, socket relocation, or ensuring the correct amperage where needed.
Running costs	Similar at like-for-like power	Similar at like-for-like power	Depends mainly on wattage, usage time, and your electricity tariff.
Total typical outlay	£380–£1,550+ (appliance + extras)	£60–£300+ (appliance only)	Built-in totals reflect installation and potential joinery.

Note: Prices are indicative for the UK and vary by brand, features, and kitchen setup. Always verify aperture dimensions, ventilation clearances, and whether a trim kit is required for your model.

Money-saving tip: If you want the integrated look without full cabinet work, choose a countertop microwave that supports an official trim kit. You’ll get a neater finish with minimal fitting costs.

Planning tip: Budget a small contingency (around 10–15%) for unexpected cabinet tweaks or electrical adjustments during installation.

Space & Kitchen Design

The choice between a built-in microwave and a countertop microwave is often driven by
your kitchen layout and how much workspace you want to keep free.
Think about whether you prefer a streamlined design or maximum flexibility.

Kitchen Situation	Best Option	Why
Small galley kitchen	Built-in microwave	Frees up worktop space where surface area is limited.
Modern open-plan kitchen	Built-in microwave	Creates a sleek, seamless look that blends with other appliances.
Rental property	Countertop microwave	No alterations required, portable if you move.
Student accommodation	Countertop microwave	Affordable, compact, and easy to take with you.
Family kitchen	Either – depends on layout	Built-in suits redesigns and frees space; countertop is quicker and cheaper.
Temporary/secondary kitchen	Countertop microwave	Practical for garages, annexes, or temporary setups.

Note: Built-in microwaves usually need a dedicated cabinet space with proper
ventilation. Always measure both the aperture and clearance requirements before purchase.

Tip: If you’re remodelling, consider placing a built-in microwave at eye level
or just above an oven tower. It’s both ergonomic and space-efficient.

Performance & Features

Choosing the right microwave isn’t just about where it sits in your kitchen — performance and features play a big role too. Here’s how built-in and countertop models typically compare.

Power Output

Built-in: Higher wattage (800–1200W) for faster cooking.

Countertop: 600–1000W, smaller units can be less powerful.

Capacity

Built-in: Larger 25–40L cavities, family-friendly.

Countertop: 15–30L, better for singles or light use.

Cooking Modes

Built-in: Convection, grilling, and combination settings common.

Countertop: Basic reheating and defrost, some add grilling.

Controls

Built-in: Touch panels, sensors, and preset programmes.

Countertop: Simple dials or buttons, touch available on premium models.

Smart Features

Built-in: Some models include Wi-Fi, app or voice controls.

Countertop: Rare, mostly limited to high-end options.

Note: A higher wattage microwave generally cooks food faster, but capacity and features matter just as much for everyday use.

Tip: If you regularly cook large dishes, look for at least a 25L capacity and 900W+ power, whichever model you choose.

For renters or students

Choose a countertop microwave. Affordable, portable, and no installation needed — ideal for moving between homes.

For modern, open-plan kitchens

A built-in microwave creates a sleek, integrated look while freeing up worktop space.

For family kitchens

Consider a built-in microwave with a larger capacity (25–40L) and higher power for cooking bigger meals quickly.

For tight budgets

A countertop microwave is the most cost-effective option, with good features even on entry-level models.

For temporary or secondary kitchens

A countertop microwave works best — quick, flexible, and easy to relocate if needed.
