SAN FRANCISCO, CA
Luxury Master Bathroom featuring Sierra towel warmers and electric floor heating
Size: 118 sq.ft. Voltage: 120V Wattage: 150 W Amps: 10 A Flooring: Tile, Marble or Stone Cost/hr *: $0.37

Behind the vintage exterior of this historic Castro neighborhood home in San Francisco, an ultra-modern design transformation was underway. The design challenge, tackled by the innovative Diego Pacheco Design Practice, was to integrate luxurious, contemporary comfort into the newly remodeled master bathroom, which features marble vanities, a walk-in shower, and a soaking tub. WarmlyYours solved this by installing a combination of electric radiant floor heating and elegant towel warmers, ensuring that every step onto the stunning tile floor is warm, and the towels are always cozy, all while operating with remarkable energy efficiency.

Integrating Modern Comfort into a Victorian Masterpiece

The original Victorian architecture of this San Francisco home concealed an interior that Diego Pacheco Design Practice aimed to reinvent with a bold, modern aesthetic. The master bathroom was a focal point of this remodel, featuring expansive tile and marble surfaces that, while beautiful, would naturally become cold and uninviting, especially in San Francisco's climate. The challenge was to introduce a layer of unseen, luxurious warmth without disturbing the clean lines and modern design.

The solution was the seamless integration of electric floor heating. Designer Diego Pacheco chose the easy-to-install TempZone™ Flex Roll to ensure the main room and even the walk-in shower floor were comfortably warm. This in-floor heating system provided perfect heat for the Tile, Marble or Stone surface, turning the cold floor into a key source of ambient comfort. The project was further enhanced with two polished stainless steel Sierra towel warmers, adding a touch of classic luxury and ensuring warm, dry towels were always on hand. The dedication to this high standard of design and comfort is a testament to the vision of Diego Pacheco, who passed away unexpectedly.

The outcome is a stunning, high-performing master bathroom where modern design meets unparalleled comfort and efficiency. The radiant floor heating system operates discretely, controlled by a SmartStat programmable thermostat, providing owners with consistent warmth and a minimal operating cost. This project is a prime example of how electric radiant heating elevates the luxury and functional value of a modern home remodel.


Featured Products 

This luxurious master bathroom project utilized a trifecta of WarmlyYours radiant products to ensure total comfort:

  • TempZone™ Flex Rolls (SKU: TRT120-1.5x56): The primary electric floor heating solution. These rolls are simple to lay out and cover large, rectangular areas like this 84 sq. ft. bathroom floor and shower space, delivering even, energy-efficient heat directly beneath the tile, marble or stone surface.
  • Towel Warmer Sierra Square 8-bars Polished Stainless Steel (SKU: TW-SR-08PS-HW): Two of these hardwired, classic towel warmers were installed. They add a touch of sophistication and provide the daily comfort of a warm, dry towel, complementing the elegant master bath design.
  • SmartStat Programmable Thermostat w/Floor Sensor (SKU: TH115-AF-GA-08): This intuitive, programmable thermostat provides precise temperature control for the heated floor, ensuring the system runs efficiently only when needed.

* This high-performance 84 sq. ft. TempZone™ Flex Roll system and its accompanying towel warmers cost just about $0.37 per hour to run, based on the average San Francisco electricity rate of approximately $0.37/kWh. That translates to an estimated operating cost of only $1.48 per day (assuming 4 hours of use) or less than $45 per month.

Frequently Asked Questions


The operating cost for this 84 sq. ft. radiant floor heating system is approximately $0.37 per hour to run at full power, based on the current San Francisco electricity rate of around $0.37/kWh. Programmed to run for an average of 4 hours a day, the cost is less than $45 a month, making floor warming an affordable luxury and an energy efficient heating solution.
While electric radiant floor heating (like the TempZone Flex Roll) is an excellent source of supplemental heat that provides superior comfort, it is generally not designed to be the sole heat source in larger rooms or cold climates. However, in smaller, well-insulated spaces like a master bathroom, especially when paired with a towel warmer, it often provides enough warmth for a comfortable environment, effectively serving as the primary heat source.
The TempZone Flex Roll system works exceptionally well with thermally conductive surfaces. In this project, Tile, Marble or Stone was used, which is the ideal choice for electric floor heating because these materials rapidly absorb and then efficiently radiate the heat back up into the room.
