Radiator during a bathroom renovation: when and how to replace it
A bathroom renovation is the ideal moment to replace the radiator too. New tiles or a changed layout can quickly make an existing radiator look out of place — and sometimes it simply does not fit in the new position.
Why replace during a renovation?
When renovating, the pipework is already open. That makes adjusting or moving the water connection relatively straightforward and cost-effective compared with a separate job later. It is also the right moment to match the radiator to the new interior.
What changes during a renovation?
A bathroom renovation typically involves:
- A new tile layout (walls, niches, built-in furniture)
- Different sanitary positions, changing available wall space
- A new interior theme — colour, style, materials
All of these affect the ideal position and format of the radiator.
Vertical or horizontal?
A renovation gives more freedom than a simple replacement:
- Vertical when limited width is available alongside new sanitary fittings
- Horizontal when wall space opens up after removing an old towel rail or baseboard heating
- A new position when the new layout frees up a better wall section
Which heating system?
Renovations increasingly coincide with a switch to a heat pump or hybrid system. If that is the case, choose aluminium: it performs better at the low flow temperatures that heat pumps use. Read more in radiator for a heat pump.
Colour and style
A renovation is a chance to make the radiator a genuine design element:
- Choose a colour that connects with the new tiles or sanitary fittings
- Consider a matte shade (soft linen, stone grey, midnight noir) for a timeless bathroom
- Think about visibility: in a small bathroom, a radiator that blends into the wall reads calmer than a strong contrast piece

What does it cost?
Replacing a radiator during a renovation costs less than a standalone job later, because the pipework is already open. Expect:
- €350–€700 for the model
- €80–€200 for connection (via a plumber)
- If the connection needs to be moved: €200–€500 extra for pipework
Ask your contractor to include this in the renovation quote.

Frequently asked questions
Why is renovation the best time to replace a radiator?
Because the pipework is already open. Moving or adjusting the connection costs much less than a standalone job later.
Do I need to update the heating system when renovating?
Not necessarily, but a renovation is a good opportunity to consider switching to a heat pump — and choosing the right radiator type for that.
