It isn't expected but it is nice to have.

If you are just doing electric radiant, about 1/2 inch by my memory. If you are doing pex, that is done under the subfloor and not any thickness.

Climate and floor type matter a lot. We are in a mild climate (NC) and have engineered hardwood in the bathroom. I've done it with tile but in a large bathroom, the electricity use adds up.

You might want to clarify what "building a new home ourselves" means? And what is "high end" varies based on your frame of reference.

As above. Definitely required in our area (first snowfall of the season last night, up to a foot in the subs) at least in the master, for homes above C$1m (US$750k).

In my area it is expected in new builds even in the $500k us Price range. It is such an easy an relatively inexpensive add on when building and such a nice feature to have.

Thank you all for responding. We’re in Ohio so more on the nice to have and maybe needed once in awhile. Any recommendations on type/product for ease of install and reliability?

I did an electric system in my master bathroom tile floor and we love it. Very cheap to operate, works fast, programmable, doesn't raise the floor at all so my hardwood to tile transition is completely flush.

If all you want to do is 1 bathroom, I 1000% recommend just doing electric in it. If you want an entire floor done, that's where you do the expensive hydronic system with a boiler/pumps/pex

We used to live in a house with an electric system under the bathroom tile floor. The shower was curbless and the heat went even under the shower floor. It was wonderful!!! Warm feet whenever in the bathroom or shower. Shower and towels dried quickly and never got musty or mildew-ey. When not feeling well, we would sometimes go and lie on the bathroom rug because the warmth felt so comforting.

I installed the electric version in our old house when I redid the bathroom. My only caution with it is...... That they are so wonderful, you will never want to be in a house without it!!! LOL seriously, it is a really nice luxury. Pair it with a towel warmer. Bliss!

Individual results may vary: We installed electric floor heat in our master bath 13 years ago. My wife liked it at first, the warmth on the feet, but within a year she decided that she preferred the feel of the cool tile instead. It hasn't been used since. Happy wife, happy life.

I suspect how warm you keep your house and climate explains the variability.

Ohio is fairly diverse climate wise but still would be nice to have.

My 240V story. The electricians didn't wire for 240 so I had to live with 120 - made for a slow warmup so that we had to leave it on all the time. Made for a warmer bathroom that we wanted. I lived there for 8 years and never got around to running another line (or stealing the tubs that we never used) to get 240.

In a large master, I was quoted $3k 10 years ago so we all need to clarify what "inexpensive" is.

In central NC, it was completely unique. You don't see it except occasionally on $2M builds.

Life hasn't been the same since we got heated flooring in our new bathroom.. a little on the pricey side as a luxury addon, but you wont regret it during the winter!

In 2007, my DIY cost on floor heating was under $600.

Looking to get electric heated floor for the bathrooms as well? Is the consensus the 220V version is the one to get? Thanks
