I’m a DIY retired surgeon.
Over the years I’ve tiled entire bathrooms, kitchens, rec rooms, laundry and utility rooms maybe 40 times. I’ve done three heated floors, twice with WarmlyYours products.
This go around I used the WY Custom Matt offering which is not well represented on their website. The Matt material looks and feels like landscape fabric. The heating wires are sandwiched between a layer of fabric on each side. The Matt is cut according to the precise floor plan that you provide. My floor plan had a number of corners, etc so I felt the custom mat was going to be easiest to install. Only one hint to share . Use ALOT of thin set between the mat and tile. Otherwise the tiles will seat on top of the wires and you will have issues with tiles teeter tottering on the wire and even after the thin set cures there can be enough movement still on the tile that your grout will pop out. This is tough to remedy later since you run the risk of damaging the wires if you try to pull up tile that is stuck to the mat. The toothed trowel bumps ove the wires as you spread the thin set creating an uneven bed of thin set. The day they come up with a mat that has a consistent thickness they will have a true winner.
