Bathroom renovation with underfloor heating: what should you know?

A bathroom renovation with underfloor heating is appealing to many people. You do not step onto an ice-cold tiled floor in the morning, and heat is distributed evenly throughout the room. Underfloor heating also fits perfectly with the calm appearance of a modern bathroom. However, it is not a choice you should only make when selecting your new floor tiles. Underfloor heating is part of the bathroom’s construction. The available height, subfloor, chosen floor finish and the way you want to heat the bathroom all play a role. A complete bathroom renovation is therefore the ideal time to explore which solution suits the space. In this blog, we explain what you can consider beforehand and why underfloor heating is more than just a luxury addition.

Why choose a bathroom renovation with underfloor heating?

For most people, comfort is the main reason.

Tiles are practical in a bathroom, but they can feel cold. You notice this immediately on cold mornings when stepping out of the shower.

A heated floor changes that experience.

The warmth comes from a large surface, so it is experienced differently from heat coming from just one radiator.

But comfort is not the only benefit.

Underfloor heating can also be interesting from a design perspective. When the chosen heating solution allows it, you may not need to account for a large radiator on a wall.

That wall space may then be used in a different way.

Consider heating before the renovation

With a bathroom renovation that includes underfloor heating, the choice needs to be made early in the design process.

Why?

Because underfloor heating sits beneath the finished floor.

A floor consists of several layers that need to work well together. If you only decide at the end that you want underfloor heating, it can affect choices made earlier.

That is why it is important to discuss how you want to heat the bathroom at the start of a renovation.

This allows the floor, finishes and other elements to be considered as one complete whole.

Electric or water-based underfloor heating?

Broadly speaking, there are different ways to heat a bathroom floor.

Which solution is suitable depends on the property and the existing technical situation.

Electric underfloor heating

Electric underfloor heating is powered by electricity and can be an interesting option for a relatively limited floor area, such as a bathroom.

One advantage is that the system can be installed specifically for the bathroom.

How suitable this solution is for your situation depends, among other things, on how the room is used, the available electrical capacity and how you want to heat the space.

Water-based underfloor heating

With water-based underfloor heating, heated water flows through pipes in the floor.

This solution can be interesting when the property already uses a suitable heating system or when underfloor heating is also installed elsewhere in the home.

However, the possibilities vary greatly from one property to another.

That is why it is wise not to decide in advance that one system is always better.

The home’s technical situation should be included in the decision.

Bathroom renovation with underfloor heating and floor construction

An important consideration in a bathroom renovation with underfloor heating is the complete floor build-up.

A floor is not simply a structural floor with a tile on top.

You need to account for the subfloor, any heating solution, suitable finishes and the final floor level.

This is especially relevant at the transition to the space outside the bathroom.

Pay attention to the height difference at the door

No one wants an unexpectedly high and inconvenient step into the bathroom after a complete renovation.

That is why you should consider in advance how the new floor will be built up and which level it will ultimately reach.

In an existing home, the available space can be limited.

A complete renovation gives you the opportunity to assess the existing floor and determine which build-up is technically suitable.

Which tiles work well with underfloor heating?

Tiles and underfloor heating are often a good combination.

Ceramic tiles conduct heat well while also being practical in a humid space.

However, this does not mean you only need to consider heat conductivity.

The tile also needs to suit the look of the bathroom and be appropriate for the area where it will be used.

For example, consider the requirements of a floor in a wet environment.

Large tiles for a calm look

Large floor tiles are popular in modern bathrooms.

They create fewer grout lines and can therefore give a calm, spacious appearance.

Combined with underfloor heating, they create a floor that looks sleek and feels comfortable.

However, the selected tile should suit the dimensions and shape of the room.

The largest tile is not automatically the best tile.

Where should underfloor heating not be installed?

An interesting question during the design process is where heating is actually needed.

Not every part of the floor is automatically a logical place for it.

For example, the situation beneath fixed elements may differ from the open floor area where you walk.

That is why the installation plan should be coordinated with the final bathroom layout.

This is another reason not to make the different choices separately.

Creating a random heating plan first and only then deciding where all furniture and sanitaryware will go does not make sense.

The elements need to work together.

Underfloor heating and a walk-in shower

A common question is how underfloor heating works in relation to a walk-in shower.

A shower area has specific requirements because of drainage, floor slope and floor construction.

That is why the design needs to carefully consider how the shower zone and heated floor area relate to each other.

Careful preparation is especially important with a fully continuous tiled floor.

Visually, you want the floor to look like one calm whole.

Technically, the shower must function properly at the same time.

Do you still need a radiator?

With underfloor heating, the question quickly arises whether you still need a radiator.

There is no universal answer.

It depends on factors such as the size of the bathroom, heating output, room insulation and the system being used.

A radiator can also have a second function.

For example, a towel radiator can be useful for hanging towels.

But if you do not need that function and the room can be heated sufficiently in another way, you may prefer to keep the wall free.

So have the heating needs of your bathroom assessed, rather than automatically reinstalling the same heating solution.

A bathroom renovation with underfloor heating gives more design freedom

A bathroom renovation with underfloor heating can influence the look of the room.

A traditional radiator takes up wall space and attracts visual attention.

When a radiator is not needed, or is less prominent, it can create additional freedom.

Perhaps the bathroom unit can be wider.

Perhaps there is room for a tall cabinet.

Or you may deliberately keep a wall empty to make the bathroom feel calmer.

This clearly shows how technology and design are connected.

A technical choice beneath the floor can ultimately determine what the visible bathroom looks like.

Also consider temperature control

Comfort does not mean the bathroom needs to be heated to its maximum temperature all day.

The way you can control the temperature is especially important.

When do you use the bathroom?

For many households, these are mainly clear moments in the morning and evening.

Depending on the chosen system, suitable control options may be available.

It is wise to discuss in advance how you use the bathroom and what level of comfort you expect.

This prevents the focus from being only on the system instead of your daily routine.

Is underfloor heating only suitable for luxury bathrooms?

No.

Underfloor heating is often associated with luxury, but the comfort it provides can be valuable in many different bathroom styles.

Whether you choose Japandi, hotel chic, modern, minimalist or a warm beige bathroom, the heating is largely out of sight.

That is exactly what makes it interesting.

You add comfort without adding another visually prominent element to the design.

And that suits bathrooms where calm and simplicity are central.

Combine underfloor heating with warm materials

A warm floor does not automatically make a bathroom feel visually warm.

Colour and materials are just as important.

For example, combine a comfortable floor with wood-look finishes, sand tones, natural stone looks or warm neutral shades.

This creates warmth on two levels.

The floor feels pleasant, while the space also has a soft appearance.

This can work especially well if you like a calm, wellness-inspired or hotel-like atmosphere.

Consider the complete picture during a renovation

The most important thing with underfloor heating is not to see it as a separate product.

The choice is connected to:

  • The existing property
  • The subfloor
  • The floor build-up
  • The type of tile
  • The layout
  • The shower zone
  • The desired temperature
  • Any additional heating

That is why the question of underfloor heating belongs at the start of the design process.

Not at the end.

When all elements are considered together, the result can be much stronger both technically and visually.

Bathroom renovation with underfloor heating? Discuss it in advance

Would you like a bathroom renovation with underfloor heating? Mention this wish early in the process.

This allows the available space, floor build-up, layout and appearance to be considered from the start.

Perhaps underfloor heating will prove to be a perfect match for your wishes. Or perhaps your home requires a specific solution. It is better to know that beforehand than when the new bathroom has already largely been decided.
