Invisible Comfort, Visible Value: Why Radiant Heating is the Ultimate Bathroom Upgrade

A Luxury Transformation in Cottage Grove, MN

Villareal Master Bath  (6)

The Cure for the Common Cold Floor

For many homeowners in Minnesota, the morning routine begins with a reluctant dash across a freezing tile floor. We’ve been conditioned to think that cold stone is just a "part of winter," but it’s actually a design flaw that impacts your comfort every single day.

In this Cottage Grove residence, the challenge was a spacious 86-square-foot bathroom that felt more like an ice box than a sanctuary. By integrating a WarmlyYours TempZone™ Cable system beneath the tile, professional installer Brad Randall transformed a functional necessity into a spa-like experience, ensuring that the first step out of the shower is always the best part of the day.


Project Details


A Partnership in Professionalism

In northern climates like Minnesota, standard home heating often struggles to reach the floor level, leaving a layer of cold air right where your feet land. This homeowner was installing a beautiful new tile floor over a wood subfloor—the perfect opportunity to fix the "cold floor problem" permanently.

The project was executed by Brad Randall of Randall’s Home Improvement, a seasoned pro who has been a loyal WarmlyYours partner since 2010. Having installed everything from Environ mats to pipe freeze protection, Brad brings a level of expertise that ensures long-term reliability. For this build, he utilized the Prodeso™ Membrane, which provides perfectly spaced channels for the heating cable and acts as an uncoupling mat to protect the tile from cracking. Whether he’s using a thermal camera to troubleshoot or designing a custom layout for nailed hardwood, Brad’s deep history with radiant technology means the homeowner gets a system that is as durable as it is comfortable.

Featured Products

  • TempZone™ Floor Heating Cable: The heart of the system. This flexible cable allows for custom coverage, ensuring every corner of the bathroom—from the vanity to the toilet area—is wrapped in warmth.
  • nSpire Touch Thermostat: A sleek, programmable interface that allows the homeowner to schedule warmth. You can wake up to a 80°F floor and have it automatically power down while you're at work.
  • Prodeso™ Membrane: This "smart" underlayment allows for an incredibly fast installation and provides vapor management and uncoupling benefits for the tile.

* Operating at 1,046 Watts, this system costs approximately $0.19 per hour based on current local rates. When used with a programmable thermostat for 4 hours a day, total costs are only $0.76 per day—providing high-end comfort for roughly $22.80 per month during a Minnesota winter.
