Understanding Underfloor Heating for Bathroom Renovations: The Basics
What is Underfloor Heating and How Does It Work in Bathroom Renovations?

Underfloor heating, also known as floor heating, is a hidden system that delivers warmth evenly across your bathroom floor—unlike traditional radiators, which heat air from one side of the room. Electric underfloor heating uses a heating mat or flexible heating cable installed directly beneath your tiles, while wet underfloor heating (or "warm water" systems) circulates hot water through pipes beneath the floor. These systems are designed to operate efficiently with today’s energy standards, using insulation boards to direct warmth upwards and reduce running costs.
During a bathroom renovation, either system can be added with minimal disruption. Electric systems are especially popular in smaller spaces or retrofit projects, thanks to their low profile and ease of installation. Wet systems excel in larger spaces or new builds, offering greater flexibility with smart zoning. No matter your project, underfloor heating for bathrooms will keep your bathroom floor warm and comfortable year-round, ensuring every step is a pleasure after a shower or bath.
Benefits of Installing Underfloor Heating for a Bathroom Renovation
- Even heat distribution
- Increased comfort (especially on bathroom floors)
- Energy efficiency compared to traditional heating systems
- Enhanced property value
The biggest plus? Even heat distribution—no more chilly corners or cold spots on your bathroom floor. A true luxury, underfloor heating makes the entire space comfortable, not just the area around a radiator. With energy efficiency at its core, underfloor systems work well with smart thermostats and timers to lower your utility bills. Increased property value is another major draw—future buyers and families love the comfort and sustainability that underfloor heating for a bathroom renovation brings. Add in the sleek look (no bulky radiators interrupting your bathroom design) and it’s easy to see why more UK homes are choosing this upgrade.
Types of Underfloor Heating for Bathrooms: Electric vs Wet Systems
| Type | Description | Ideal Use Case | Cost | Installation Complexity |
|---|---|---|---|---|
| Electric Underfloor Heating | Uses electric cables or mats | Bathrooms, small spaces | ££ | Easier retrofit |
| Wet Underfloor Heating | Uses warm water pipes under bathroom floor | New builds, larger spaces | £££ | More complex installation |

Choosing Between Electric Underfloor Heating and Wet Underfloor Heating Systems
Choosing the right underfloor heating system is crucial for a successful bathroom renovation. Electric underfloor heating is often the “go-to” choice for UK bathrooms being renovated, owing to its low-profile mats and minimal floor height increase (low profile). It’s quick to install and ideal for smaller, irregular-shaped bathrooms. If your project is a new build or you have plenty of space, consider wet underfloor heating. Also known as a wet system, it circulates warm water through pipes, delivering cost-effective, whole-room comfort—especially when paired with modern boilers or heat pumps.
Cost and complexity are important considerations. Wet systems generally have a higher up-front investment, but offer long-term savings in larger areas. Electric systems are easier to install and usually chosen for their simplicity and speed—perfect if you want to finish your renovation project quickly. If unsure, consult expert advice from an experienced installer like Peak Underfloor Heating Ltd to ensure you get the perfect heating for bathrooms in your home.
Key Components: Insulation Boards and Smart Heating Controls
The Role of Insulation Boards in Underfloor Heating for a Bathroom Renovation
Insulation boards are the secret weapon for an efficient and comfortable bathroom underfloor heating setup. Fitted beneath your underfloor heating mat or warm water pipes, they focus heat upwards—right to your bathroom floor—rather than losing it to the subfloor below. The result is quicker warm-up times, lower running costs, and increased energy efficiency. For electric underfloor heating especially, modern insulation boards are easy to install, lightweight, and can often be cut to fit any bathroom floor layout.
Not only do insulation boards aid energy efficiency, but they also help protect the substrate and reduce wear on your heating system over time. Any professional will confirm: A quality insulation board is essential for achieving a warm, responsive, and cost-effective underfloor heating experience in your bathroom.
Smart Controls for Your Bathroom Underfloor Heating System

Adding smart heating controls takes your bathroom underfloor heating to the next level of convenience and energy savings. Today’s digital thermostats and wireless controllers allow precise temperature scheduling for your bathroom floor—meaning you only heat the room when you need it. Many smart controls offer app connectivity, letting you adjust settings from your phone, and learn your habits over time to optimise both comfort and energy efficiency.
For families on the go, or for those who want ultimate control over their heating system, these smart controls are a game-changer. Not only do they maximise the return on your underfloor heating for bathrooms investment, but they also help prevent wasted energy and unexpected bills.
