@Jordan Lagrassa  so, Jordan   knob and tube wiring is very old... it is called this because they would run single wires thru spaces and attach the wire to a porcelain knob so it wouldn't contact the wood for the most part and when the wire came up to a wood member to pass thru it they would drill an oversized hole and slide in a porcelain tube kinda like a mouthpiece on a trumpet....kinda and then run the wire thru this tube.  

I know I saved a lot of hassle and money that way.I'm glad I knew how to do some jobs myself, so I could save the installation costs on things like natural stone tile - it isn't any harder to install than porcelain or ceramic, but looks 1000% better.

As to the tile, when I lay that "Porcelain fake wood" I don't lay it as a tile, as I see they have done in your photo, @Aaron Mazzrillo.

Looking to put under floor heating in a porcelain tile bathroom on a flip. 1/2 inch Durock base.Pros and Cons of type:Install tips:Anything would be appreciated I haven't been able to find much solid info online.Take Care

Baths flooring is 18x24 porcelain tile.  

I still prefer porcelain tile in the baths/shower areas but lvp everywhere else!

Admittedly we only use porcelain as we found the 49cent ceramic tile from HD or Lowes is fragile & rarely geometrically consistent.

@JJ Buckner if it is porcelain then just have it refinished.

By the way , i was also looking at thin slabs which weight less and easy to cut , they should be installed on plywood  , but provide the same benefitsother options I considered are Porcelain slabs / corian , its very thin , but it looks like there are no price savings , but atleast they could be transported easily , if in case you find a good deal a little farther from your place

The wiring method is probably one of the safest as it was built, at the time it was built, because the grounded and ungrounded conductors are on opposite sides of a stud bay, everywhere the goes through a wood structure there is a porcelain insulator and the wires are remote from the wood in the structure because they are attached to porcelain insulators instead of nailed to the wood.
