Stepping into a shower on a chilly North Carolina morning shouldn't mean stepping onto shock-inducing cold tile. For this residential project in Wilmington, the homeowner, Brad Jacobs, wanted to eliminate that discomfort and add a touch of luxury to a new walk-in shower build. By utilizing WarmlyYours in-floor heating, the project successfully turned a standard daily routine into a spa-like experience, ensuring the tile remains warm and dries faster after use.


Project Details


Bringing Warmth to the Water

The Challenge: Cold Tile and Complex Layouts Tile and stone are popular choices for showers due to their durability and aesthetic appeal, but they are naturally cold materials that steal heat from bare feet. For this Wilmington home, the goal was to install a heating solution that could handle the unique requirements of a "wet area." The challenge with shower installations is accommodating the slope of the floor toward the drain while ensuring total waterproofing integrity.

The Solution: Flexible Cable for Precision Heating To navigate the sloped floor and the drain location, the installer utilized TempZone™ Floor Heating Cable. Unlike fixed mats, the free-flowing cable allowed for a custom layout with 3.75-inch spacing, ensuring even heat distribution right up to the drain. The installation was fortified with Prodeso waterproofing accessories (bands and corners) to ensure a watertight seal—critical for protecting the wood subfloor in a wet environment.

The Outcome: Efficient Luxury The result is a highly responsive radiant floor heating system that warms up quickly. Beyond the immediate comfort of warm feet, the heat assists in drying the shower floor surface faster after use, reducing humidity and mold potential. Paired with the nJoy WiFi Thermostat, the homeowner can schedule the floor to be warm exactly when they wake up.


Featured Products

TempZone™ Floor Heating Cable (Twin Conductor): Chosen for its maximum flexibility, allowing installers to easily maneuver around shower drains and fit complex room shapes.

  • nJoy WiFi Thermostat: A programmable thermostat that offers remote control via WiFi, ensuring the shower is warm before you even step out of bed.
  • Prodeso Accessories: ProBand and preformed corners were used to ensure the integrity of the waterproofing in the shower corners and seams.

* Based on Wilmington’s average electricity rate of $0.16/kWh, this 264-watt system costs just $0.04 per hour to operate. Running it for an hour each morning adds up to less than $1.30 per month, making daily luxury surprisingly affordable.

Frequently Asked Questions


A. Yes, absolutely. Systems like the TempZone™ Cable are wet-rated and specifically designed for installation under tile in showers. When installed correctly with a GFCI-protected thermostat (like the nJoy) and proper waterproofing, it is perfectly safe.
A. Beyond comfort, floor warming helps dry the floor surface faster after a shower. This rapid drying process reduces the moisture available for mold and mildew growth, keeping the shower cleaner.
A. Yes. In this Wilmington project, the subfloor was wood. The system generally requires a backer board or a proper uncoupling membrane/mortar bed to stabilize the tile, but the heating element itself is compatible with wood subfloor assemblies.
A. No, because the square footage in a shower is usually small (22 sq. ft. in this case), the energy draw is minimal. It generally costs pennies a day to operate.
A. Tile, marble, and stone are the best conductors of heat, making them the most efficient and effective choices for electric radiant floor heating systems.
