Bathroom Floor Underlayment – Part 1

Before the tile can be installed on the bathroom floor, we had to install the heated floor mats. Yes, that’s right…heated floor. AWESOME!

To install the floor, we first scrubbed and scored the plywood subfloor really well. Then we layed out our 2 floor mats – 15′ and 10′.

We used this super cute little stapler to staple them down

and then hit anything sticking up with a dab of hot glue.


The wires from the mats along with 2 thermostat wires are pulled up to the box that will hold the controller. We left a pull wire for just this purpose.

We have 2 thermometers embedded in the floor. One is a backup. The thermometer is one of the most likely failure points so a spare is good.


I hot glued all the wires so they stay down nice and tight. Nothing was moving at all.

After the heating mat, it was time for the self leveling compound.

Check out PART 2 for more details.

Whoo heated floors. My toes are soooo excited. My feet are looking forward to it as well.

Cutting Holes in Plaster and Lath

We also went to work getting the electrical box holes made.  Our technique was to start with a tile bit on the roto-zip.

We used that to cut through the plaster in a controlled fashion.  I’ve seen that you can use a utility knife and plan on dulling the blade with each cut but since we have the roto-zip, we used that.  The roto-zip makes a HUGE mess so the shop-vac attachment is a must even in our dirty dusty house.


After the plaster is removed from the opening, we changed out the bit for a multi-purpose wood bit.


For the low-voltage work (ethernet, cable, and phone) the backless low-voltage boxes will work.  However, we are having insulation blown in and the backless boxes are just going to fill with insulation and make a big mess so we opted to use plastic boxes.


I’ve still got a bunch more boxes to do but this is a well-compartmentalized project that I can do between helping Stefan with the “heavy lifting” on some of the bigger projects.  I am determined not to just be a tool girl but at the same time I have a hard time controlling some of the tools so projects like these outlet boxes are great for me.  They allow me to get stuff done independently of any heavy machinery.

That’s the short version of how to cut a nice hole in plaster and lath.  Do you have any preferred plaster cutting tools or does the term plaster and lath just make you ever more thankful for your nice drywall walls?


Rug Buddy – cool things I want!

We went over to some friend’s house last week for a movie night.  After being encouraged to take of our shoes, we stepped onto a rug and it felt like heaven!  They had recently purchased a Rug Buddy.

This is basically a heated rug pad. It was seriously amazing. They are pricey at nearly $300 but for a family room with 2 little ones, it was definitely a good purchase for them. It got me thinking, why couldn’t you use a heated mattress pad for something similar? I think the concern would be that you could scald your floor but if you sandwiched the heated blanket between the rug and the pad you shouldn’t have that problem. It is possible that you would be able to feel the heating element though. Hmm.

I think our best bet is to wait for these to catch on in a big way for the price to come down. It was awesome enough for me to write this post so I’m guessing they’re going to be the next big thing. You heard it here first.
