I'm super happy with the product! Really simple to install, even has double sided tape if you choose to use it to stick it to the floor prior to the tile installation. My recommendations however based on my experience:
- Use a bit more mud when applying the tile. We had a few cases where the mat interfered with good adherence. Just go a bit heavier.
- plan out the room prior to laying the tile. We started laying out the room as we began tiling, we cam up like 2.5 feet short which was a bit frustrating. So follow the instructions better than I did and lay the entire thing out prior.
- plan for your wires going to the thermostat before installation. I already had the tile in and was required to cut into the drywall to hide the thermostat wire and electric cable behind the baseboard.

Other than that, I really like it, heats up pretty fast and gets the space nice and warm.

Installation was easy. I poured self-leveler over it for a basement bathroom. If that is your plan as well, I would STRONGLY suggest that you buy a hot glue gun and glue down each and every point where the wire turns. I'd also just glue down the mesh everywhere. I only glued down parts that were lifting and I ended up with a lot of coils becoming buoyant and lifting out of the cement before it dried. I had to chip the cement down in certain places to get the coils down.

Warmth is ok. It takes a long time to warm up cement. Found it took about 12 hours to get up to a reasonable temperature. Probably not so long if just covered in mortar and tile. We'll be setting it and leaving it on because of the time it takes.

Thickness was fine, in places where the coils didn't lift it wasn't an issue.

My husband and son installed this under a slate bathroom floor. Reading lots of comments was very helpful with the best advice being testing and more testing. It was tricky, don't get me wrong, but not too difficult for a diyer.
We've been using this for the past month and I'm very pleased. It's the only heat in this medium sized bathroom and so far with temps going down to the 30's at night, it's all we need. Hopefully this lasts a good long time.

We just finished tiling the bathroom. We had 2ft/1ft tiles so we had to build up our mortar high, but it wasn't too big a deal. The electrical work is trivial. The people complaining here probably just don't do electrical work often. No different than wiring an outlet. The GFCI input is just normal 120VAC or 240VAC, and the output to the heating element is unpolarized, so it doesn't even matter how its hooked up. Same with the sensor, you just slap it where it tells you to in the instructions. The directions are crystal clear for anyone that knows what they're doing, they do not use a crazy amount of jargon, and amazing pictures, along with how to test it with an ohm meter. It's 12W / sqft, so the unit i bought will use 3 amps. They recommend a dedicated circuit, which isn't hard to install itself either. I just bumped my outlet up to a 20amp circuit and hooked it into that preexisting one.

I'll probably get the same system again when i finish my in law suite. This was an excellent addition for my upstairs bathroom remodel.

I hesitated to buy one of these floor heating systems because I was afraid it would stop working in a few years, and installation isn't cheap if you're not doing it yourself. However, our architect told us that the system (not sure which brand) in his home has been going strong for 15 years. Our contractor didn't have any great problems installing it in the floor just outside the walk-in shower, and it's working great. Our floor was 70 degrees this morning, although the shower room has walls on three sides exposed to the exterior of the house, the house is on a slab, and it was 3 degrees F. Be sure to get the alarm.
