How Much Does Bathroom Radiant Floor Heating Cost?

It seems like a far-fetched fantasy: You step out of a nice, hot shower directly onto the bathroom floor, and ... the tiles don't immediately turn your toes to ice. How could this be?

Radiant floor heating offers a cozy way to overcome freezing cold bathroom floors. It can also be used for whole-house heating in some situations. Make your fantasy a reality: Here's how much you need to budget for this project.

How Do Radiant Heated Floors Work?

Bathroom radiant floor heating uses either tubes of hot water or electric wires running underneath the flooring to generate heat. As the selected heating element gets hotter, the heat transfers to the flooring material. The heat rises throughout the room, making the floor feel warm to the touch and heating the air. Because of this, the floor heating system can heat your entire home when it's planned and installed correctly.

Types of Radiant Floor Heating Systems

The two common types of bathroom radiant floor heating are hydronic and electric. Learn the differences and the average costs to help you decide which to install.

Hydronic Floor Heating

With a hydronic floor heating system, the configuration uses tubes running under the floor where heated water runs to heat the flooring. It's often used for whole-house heating over larger spaces and is more cost-effective if you already have a boiler, which is required to heat the water. Hydronic floor heating is energy-efficient and works with most energy sources, including solar power and natural gas. You can install it over the subfloor or embed it into a poured concrete floor.

Hydronic floor heating is typically more expensive overall if you don't already have a boiler. The average boiler cost is $3,200 to $9,000 (CAD 4,536 to CAD 12,758), according to HomeGuide. If you already have a boiler in your home, you can connect the floor heating to it. The cost of the floor heating system is $7 to $17 (CAD 9.92 to CAD 25) per square foot.

Electric Floor Heating

Electric floor heating uses electric coils underneath your flooring. Electrical currents run through the coils to heat the floor. This option is often used for a single room, which makes it an ideal option if you only want to install it in your bathroom. It's best for supplemental heating rather than whole-house heating. Electric radiant floor heating costs an average of $8 to $15 (CAD 12 to CAD 22) per square foot.

Additional Costs

Keep in mind that the radiant floor heating costs only account for the heating system itself. You also need to install new flooring to go over the heating elements. This can vary significantly depending on what type of flooring you choose, but you can expect a cost between $4 and $15 (CAD 5.67 and CAD 22) per square foot. If you're only installing the flooring in your bathroom, the total costs may be relatively affordable because of the smaller floor space.

Are Heated Bathroom Floors Worth It?

Whether bathroom radiant floor heating is worth it depends on your situation. You'll typically pay a lot up front to install radiant floor heating, but it can save you money on heating costs in the long run. Evaluate the costs of the project and consider the potential benefits to help you decide if it's a good investment. You may find you're willing to pay the price to have toasty, warm floors and an added source of heat in your bathroom.

However, keep in mind there are drawbacks. You'll need to redo your floor, so this option is likely only worth it if you're building a new home or remodeling your bathroom completely. If you're installing the in-floor heat system in an existing home, you'll need to raise the floor to accommodate the heating elements. That can throw off the other features of the room and create a drop-off with the adjoining room.

Heated floors may also not be worth it in certain climates. If you live somewhere that's warm most of the year, the added heat underfoot isn't necessary. However, if you live in an especially cold climate, you might find that you benefit from the extra heating and warm feeling in your bathroom.
