The Silent Chill of Luxury Flooring

Most homeowners in the South accept a frustrating trade-off: they love the elegance of tile and marble but dread the "cold shock" that greets their feet every morning. In Slidell, Louisiana, high humidity and concrete slab foundations often turn beautiful master bathrooms into damp, chilly "ice boxes."

Beyond the Surface

Concrete slabs are notorious heat sinks. They pull warmth out of the room and keep tile floors uncomfortably cold, regardless of what the thermostat on the wall says. For this Slidell master suite, the goal was to create a spa-like environment that felt warm from the ground up.

Healthy Home Solutions, LLC utilized the TempZone™ Cable system, spaced at 3.75 inches, to provide 135 square feet of consistent, radiant warmth. Unlike forced-air systems that blow dust and allergens around while leaving the floor cold, this radiant system warms the objects in the room—starting with you. The result is a bathroom that feels dry, cozy, and truly luxurious, even on the dampest Louisiana mornings.

Featured Products

  • TempZone™ Floor Heating Cable (120V): The core of the system. This flexible cable allows for custom coverage around bathroom fixtures, ensuring no "cold spots" near the vanity or toilet.
  • Prodeso Membrane Roll (162 Sq. Ft.): This uncoupling and waterproofing membrane is a triple-threat solution. It acts as a crack-isolation barrier to protect your tile from shifting, provides waterproofing for the wet bathroom environment, and features pre-spaced "studs" that make installing the heating cable fast and perfectly consistent.
  • SmartStat™ Programmable Thermostat: Eliminates energy waste by allowing homeowners to schedule heat exactly when they need it (like 6:00 AM) and lower it when they don't.
  • Circuit Check™: A vital safety tool used during installation to ensure the heating system is 100% functional before the tile is set.

* This 135 sq. ft. system operates at about $0.19 per hour. If used for 4 hours a day, it costs roughly $0.76 per day—less than the price of a single cup of coffee per week.
