Just floor heating won’t be enough. You will have to add supplemental room Heat too. And turn the whole bathroom into a sauna. With additional ventilation too. Add 15-20K to a room you use less than an hour a day. Not counting the upcharges for the structural alterations for the curbless shower.

Because it’s not just “cold”. It’s freezing with that much 70 degree air volume and you in 105 degree water.

Heated floor will not help you to heat up the room. You can add a baseboard heater if you want to warm up the room and looks slick so its not going to disturb the design elements in your bathroom. Not sure what your budget is for the bathroom but you should definitely use it towards a heater if you're not getting enough heat there.

Not sure what costs are in New England for labor but they have Fully electric heater or steam/electric heaters.

Looks like I am hijacking this thread! :-)

Mostly, I love the look of the bathroom above, but it also fits the Universal Design idea – right? It sounds like staying warm is the main drawback and I am willing to ditch the idea if necessary. However, I would like to explore ideas for keeping the room warm.

I like the idea of warm floors, but not sure of the cost, and some of you don’t think this will work. I like the idea of a baseboard heater if that would work, but what about something dedicated to the task? What about a Fan/Heat combination like this: https://www.amazon.com/dp/B001CJUKZS/?tag=googhydr-20&hvadid=190489761596&hvpos=1t1&hvnetw=g&hvrand=4158767817143482295&hvpone=&hvptwo=&hvqmt=b&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9031150&hvtargid=kwd-295772741219&ref=pd_sl_fbqrluz4i_b#customerReviews

What about heated towel bars – might they help?

Jeri,

It's not about whether it will work, it's about whether paying for all the labor/materials will fit within your budget and if it is that important for you to pay for.

Ceiling heat/fan can work but that's if you have space in your ceiling or wall (depending where it makes more sense to put it).

Towel warmers does what it says. It warms your towels not room.

So is taking a shower in a wet room colder than an enclosed shower? Sounds somewhat miserable. I'm also considering a similar setup, but am hesitant because I don't want my kids wasting all the hot water to overcompensate for an open air shower AND am worried about water being EVERYWHERE. I feel like it can pretty much be contained in the shower area, but many people have commented that it soaks everything and needs to be dried EVERY time you shower. True or not true?

I live in Korea where wet bathrooms and floor heating is the norm. but oddly enough, bathroom floors are one of the spaces that aren't heated!

We manage to keep fhe space dry enough that we don't have or need bathroom slippers. I leave the fan on and door open until everything is dry.

It's not particularly cold and drafty in our bathrooms, even in winter, with no heat in there. North American bathrooms are much larger and usually have higher ceilings so probably more prone to bwing cold.

Old thread; but yes, open showers are cold unless you live in Costa Rica and your shower is outside. And I can't imagine the light fixture in the insp pic is per code.
