Our Picks: Best Bathroom Radiant Floor Heating reviews
1. BLARALA 100 Sq. Ft. System: Best for Larger Floor Areas
The BLARALA kit covers 100 square feet and runs on 120 volts. It includes a heating mat, a programmable thermostat with air and floor sensors, and a cable monitor or alarm. The thermostat also has built-in GFCI detection, a child lock, and overheat protection.
The mat measures about 19.69 inches wide by 65.62 feet long. Its adhesive backing is designed to help hold it flat on the subfloor, and the mat can be cut, flipped, or rotated to fit a planned layout. That flexibility applies to the mat, not the heating cable: the blue cable must not be cut or shortened.
At 12 watts per square foot, the listed 100-square-foot system draws 10 amps at 120 volts. Its larger coverage may suit a broad bathroom floor, but the actual heated area depends on the room layout and clear floor space. Check the installation instructions and have an electrician verify that your circuit is suitable before buying.
Pros:
- Largest listed coverage in this comparison
- Programmable thermostat includes air and floor sensors
- Mat can be rearranged to suit the installation layout
- Cables are described as CSA-certified and safe for wet locations
Cons:
- Its 10-amp load makes circuit capacity an important planning step
- The heating cable cannot be cut or shortened to fit
Verdict: Choose the BLARALA if you need a 120-volt mat with substantially more coverage than the compact LuxHeat kits, and your floor plan and electrical setup can accommodate it.
2. LuxHeat 20 Sq. Ft. Kit with Prova Membrane: Best All-in-One Tile Package
This LuxHeat kit pairs a 20-square-foot heating cable with a 30-square-foot Prova Flex-Heat uncoupling membrane. It also includes a touchscreen programmable thermostat, floor sensor, alarm, and wood float for membrane installation. The membrane is described as providing uncoupling, waterproofing, and load support for tile applications.
The kit uses 120 volts and has a listed output of 240 watts. The thermostat includes a built-in Class A GFCI and supports dual sensing, a child lock, power logging, and a seven-day schedule. LuxHeat lists a 25-year limited warranty for the heating system and a 50-year warranty for the Prova membrane; the thermostat has a separate three-year warranty.
This is a more involved choice than a simple self-adhesive mat. The heating wires must be covered with self-leveler or thinset, and the cable must not be cut or shortened. The membrane covers more area than the heating cable, so plan the layout around the 20-square-foot heated area rather than assuming all 30 square feet will be warmed.
Pros:
- Combines heating cable, thermostat, and uncoupling membrane in one kit
- Membrane is intended to support tile installation and waterproofing
- Touchscreen thermostat offers scheduling and dual sensing
- Heating cable is listed for 20 square feet at 3-inch spacing
Cons:
- Requires embedding the wires in thinset or self-leveler
- The 30-square-foot membrane area exceeds the 20-square-foot heated coverage
Verdict: This kit is a strong fit if you want a coordinated heating and membrane package for a tile project and are comfortable following its installation steps.
3. LuxHeat 50 Sq. Ft. Wi-Fi Mat: Best for Remote Thermostat Control
This 120-volt LuxHeat kit includes a 50-square-foot self-adhesive mat, cable monitor or alarm, floor sensor, and Wi-Fi programmable thermostat. The thermostat has built-in GFCI protection, a seven-day schedule, child lock, and power logging, with remote control and monitoring through Android or iOS devices.
The mat is about 20 inches wide and 30.9 feet long, with pre-spaced cable at 3-inch intervals. The mat can be turned, flipped, or rotated for layout flexibility, but the red heating wire must not be cut or shortened. The wires need to be embedded in self-leveling underlayment, thinset, or mortar.
At 12 watts per square foot, this kit is a middle ground between the 100-square-foot BLARALA and the smaller LuxHeat options. Its Wi-Fi thermostat is the main distinction; if you do not need remote control, the lower-coverage LuxHeat kits offer programmable controls without Wi-Fi. Check the room plan carefully, since the mat cannot heat areas where its cable is not installed.
Pros:
- 50-square-foot mat provides mid-size coverage
- Wi-Fi thermostat offers remote control and monitoring
- Includes a cable monitor or alarm and floor sensor
- Mat can be repositioned to fit the planned layout
Cons:
- Heating wire must be embedded in a suitable floor compound
- Wi-Fi features may be unnecessary if you only want local thermostat control
Verdict: Pick this LuxHeat kit if 50 square feet suits your layout and remote thermostat access matters to you.
4. LuxHeat 20 Sq. Ft. Self-Adhesive Mat: Best Compact Programmable Option
This 20-square-foot LuxHeat kit includes a self-adhesive mat, cable monitor or alarm, floor sensor, and programmable thermostat. The thermostat has dual air and floor sensing, built-in GFCI protection, a child lock, and a seven-day schedule. The mat measures about 20 inches wide by 12.2 feet long.
The mat has adhesive mesh on one side and double-sided tape on the other, making it easier to position and keep flat during installation. It can be turned or flipped to fit the layout, but the red heating wire must not be cut. As with the other LuxHeat cable kits, the wires must be covered with self-leveler, thinset, or mortar.
Its 240-watt output at 120 volts makes this a more compact alternative to the Wi-Fi model, with the same listed 20-square-foot coverage as the membrane bundle. The key difference is what comes in the kit: this one focuses on a self-adhesive mat and programmable thermostat rather than an included uncoupling membrane.
Pros:
- Compact 20-square-foot coverage for a smaller floor area
- Includes a programmable thermostat with dual sensing
- Self-adhesive mat can be repositioned for layout needs
- Includes a cable monitor or alarm
Cons:
- Does not include the Prova membrane supplied with the other 20-square-foot LuxHeat kit
- Heating wire cannot be cut to fit obstacles or leftover space
Verdict: Choose this version if you want a 20-square-foot mat with programmable control and already have a plan for the tile underlayment.
5. LuxHeat 15 Sq. Ft. Touchscreen Mat: Best for Very Small Areas
This LuxHeat kit covers 15 square feet and includes a self-adhesive mat, alarm, floor sensor, and touchscreen programmable thermostat. The 120-volt system is listed at 180 watts. The thermostat includes built-in GFCI protection, dual sensing, a child lock, power logging, and a seven-day program schedule.
The mat is about 20 inches wide and 9.2 feet long, which makes it the smallest option in this comparison. Its mesh and tape help hold it in place, and the mat can be turned or flipped as needed. The heating wire itself must not be cut or shortened, and it needs to be embedded in self-leveler, thinset, or mortar.
This compact coverage can suit a limited open floor area, but measure carefully before ordering. Toilets, vanities, and other fixed fixtures can affect how much floor is available for the mat. If you need to warm more than 15 square feet, the 20-square-foot model may be a better match.
Pros:
- Smallest coverage for a limited installation area
- Touchscreen thermostat includes scheduling and dual sensing
- Self-adhesive mat can be arranged for the floor plan
- Includes an alarm and floor sensor
Cons:
- Limited to 15 square feet of listed coverage
- Requires embedding the heating wire under the finished floor
Verdict: This is the practical choice when your measured heated area is small and you want a touchscreen thermostat without paying for more mat coverage than you need.
How to Choose Bathroom Radiant Floor Heating
Measure the Floor Area You Can Actually Heat
Start by measuring the open floor area where the heating cable can be installed, not the entire bathroom footprint. Fixtures and other fixed objects can limit where a mat fits. The options here cover 15, 20, 50, or 100 square feet, so choose based on your measured layout. A mat’s stated coverage is not necessarily the same as the room’s total floor area.
Choose a Mat or Cable Kit That Fits Your Installation Plan
Self-adhesive mats can help hold cable in place and make layout work more direct. A cable-and-membrane package may suit a tile project where the included uncoupling layer is useful. Each product has specific installation requirements, so read its instructions before purchasing. In particular, do not cut or shorten the heating wire; only rearrange the mat as the manufacturer allows.
Check the Thermostat Features You Will Use
Programmable thermostats can follow a schedule, while the Wi-Fi model adds remote control and monitoring. Some options include air and floor sensors, child locks, and power logging. Consider whether you want touchscreen controls or remote access, and confirm the thermostat’s listed electrical specifications work with the planned installation.
Confirm Voltage, Load, and Electrical Requirements
All five products in this comparison are listed as 120-volt systems, but their current draw differs with coverage and output. For example, the BLARALA 100-square-foot model is listed at 10 amps, while the smaller kits draw less. Have a qualified electrician check the circuit, thermostat, GFCI protection, and local requirements before installation, especially in a bathroom or other wet location.
Match the Kit to Your Finished Floor
The product information describes these systems for use under tile, laminate, or other compatible flooring, but the installation method varies. LuxHeat’s cable systems require the wires to be covered in self-leveler, thinset, or mortar. The membrane bundle is specifically presented as a tile underlayment package. Confirm that your chosen flooring and all installation layers are approved for the system.
Understand What Is and Is Not Included
Compare the included thermostat, floor sensor, alarm, mat or cable, and any membrane. The LuxHeat membrane kit includes a membrane area larger than its heated cable coverage, while the other LuxHeat kits focus on mats and controls. Check the product’s current listing and installation guide to confirm the package contents and warranty details before ordering.
Frequently Asked Questions
Can radiant floor heating be installed in a bathroom?
These products are marketed for bathroom use, and the supplied information lists the cables as suitable for wet locations. Bathroom electrical work still needs to follow the product instructions and local requirements. Confirm the complete installation plan, including GFCI protection and any waterproofing needs, with a qualified professional.
Can I cut a heating mat to fit around a fixture?
The mat may be cut or repositioned only as described in its instructions; the heating cable itself must not be cut or shortened. Plan the layout around fixtures before installation and follow the exact product guide.
How much floor area should I cover?
Measure the open area where cable can be installed, accounting for fixed fixtures and the planned layout. Compare that measurement with the system’s stated coverage. If you are unsure how much of the room should be heated, ask the manufacturer or installer to help confirm the layout.
Do these systems include a thermostat?
Yes. Each product listed here includes a thermostat. The choices include programmable models, touchscreen controls, and one Wi-Fi thermostat with remote control and monitoring.
Do I need an electrician to install a heated floor system?
Electrical requirements depend on the home, circuit, and product. Because these are hardwired floor heating systems for bathroom use, have a qualified electrician confirm the circuit, thermostat connection, and applicable local requirements before installation.
Which option is best for a small bathroom?
The 15-square-foot LuxHeat kit is the smallest option here, while the 20-square-foot kits offer a little more coverage. Measure the actual open floor area first; the best fit depends on the layout, not just the room’s overall size.
Does a heated floor replace a bathroom’s main heating system?
The supplied product details describe these as floor heating systems but do not establish that they can heat an entire bathroom as its sole heat source. Treat them as a floor-comfort option unless a qualified installer confirms that the system is sized for your room’s heating needs.
Final Recommendation
For a larger floor area, the BLARALA kit offers the most coverage in this group. The LuxHeat 20-square-foot membrane package is the most complete option for a tile-focused installation, while the 50-square-foot LuxHeat kit stands out for Wi-Fi control. For smaller layouts, choose between the 20-square-foot programmable mat and the 15-square-foot touchscreen model based on your measured heated area. Whichever system you choose, verify the layout, floor compatibility, and electrical requirements before installation.
