When should underfloor heating be installed?

Waterproofing a shower

Underfloor heating is usually installed just before the final flooring is laid. It is often a small part of a construction or renovation project. Careful planning is crucial to ensure that installing the underfloor heating does not hold up the rest of the construction.

Underfloor heating can be installed either beneath or above the waterproofing layer. This choice does not impact the effectiveness of the underfloor heating or its warranty. However, most installers prefer to install underfloor heating before the waterproofing.
