In-floor hydroponics heating isn't recommended with renovation because of the relatively high associated cost, unless you have expose ceiling from below. The other method is electrical mat or wires for small area often less than 150 sqf, however the wires/mats can be joins together to accommodate greater area but it will require an electrician to hook it up.
Try to stay away from smooth/glossy surface tiles in area that tend to have water to prevent slipping because tiles aren?t as forgiven as carpet/wood. Use sanded grout for wide grout lines to prevent cracking, and an off colour grout doesn?t show the dirt as well as white colour grout. Lighter colour tiles & grouts tend to open up small spaces, while darker colour tiles & grouts tend to close/make the space seems smaller. It is best to mix dry powder grout by siftings because the colour will be much more consistent than wet mixing.
Wipe down grout as soon as possible after grouting the tiles, and the trick to save the day is to make the consistency of the grout slightly softer than peanut butter so it will go into the grooves easily. Compass & pencil can be use to draw the wall contours or trace the cut lines at the wall with another tile.
Backer board isn't needed if your floor isn't flexing, clean, flat, and is wood/cement. 1/2" backer board can be use if the space isn't require to match another space (you don't want too high of a transition different). 3/8" or 5/16? plywood can be use in place of backer board if cost is a concern.
Make sure to screw down the joints of the sub-floors at minimum 8? spacing and same as backer boards (try to over lap the sub-floor seams with backer boards).
