Installation Insights

The project team, including architect Beverly Thomas LLC and contractor Tom, focused on an all-encompassing upgrade for the guest space. Bathrooms are essential rooms for comfort, and the material selection of tile, marble, or stone, while beautiful, is often a source of discomfort dueing to its naturally cold temperature. In-floor heating was selected as the perfect, hidden amenity to transform the experience.

The installation was designed for maximum efficiency. The small footprint was heated using a TempZone™ Flex Roll, a pre-sized mat that simplifies laying the electric heating cable uniformly. Crucially, CeraZorb® insulating underlayment was installed beneath the heating mat. This layer acts as a thermal break, preventing heat from escaping downward into the existing concrete slab sub-floor. This strategic installation ensures the system heats up quickly and is incredibly energy efficient heating.

The final outcome is a stunning, high-end guest bathroom where every step is met with gentle warmth. For the homeowner, this system provides year-round comfort and a feature that is highly sought after by homebuyers, making it a valuable and practical upgrade to the property.


Featured Products

  • TempZone™ Flex Rolls These pre-sized mats feature radiant floor heating cable uniformly secured to a durable mesh. Ideal for rectangular areas like this bathroom, they ensure consistent heat output and simplify installation, delivering even floor warming across the entire 9 sq. ft. space.
  • SmartStat Programmable Thermostat w/Floor Sensor This modern, programmable control allows the homeowner to schedule the floor warming precisely to their needs, ensuring the guest bathroom is always perfectly warm when occupied, maximizing both comfort and the system’s energy-efficient profile.
  • CeraZorb® Insulating Synthetic Cork Underlayment Used in this project, CeraZorb is an essential thermal break. By preventing heat from escaping downward into the concrete subfloor, it ensures the heating roll's output is directed upward, resulting in faster heat-up times and lower operating costs.

* This small, but highly impactful, 9 sq. ft. electric floor heating system costs just about $0.02 per hour to run. This translates to an average daily cost of only $0.13 per day (assuming 6 hours of operation) and less than $4 per month
