Drywall and Cement Board for the Downstairs Bathroom
After a hiatus from working on the downstairs bathroom for a few months I finally got back at it. In the fall I had closed up the floor and installed the underlayment, insulated the ceiling and installed the vapor barrier for the shower but then things got stalled with a busy work schedule and travel.
About a month ago Frank and I drywalled the ceiling with him holding the sheets in place while I screwed them in. It was a bit of a challenge in the tight space but we got it up together.
This past weekend I started closing up the walls in the bathroom, starting with the 1/2" thick cement board on Saturday. Cement board is waterproof making it an ideal substrate for tiling the shower surround.
Cutting cement board is the same as the score and snap method for drywall. Using a carbide cutter and a T-square score the cement board panel a few times making a groove in the cement and cutting through the glass fiber mesh.
Next bend the panel so it snaps along the groove.
Finish by using a utility cutter to cut the glass fiber mesh on the back side.
To install the cement board in the shower surround it is important to use screws that are designed for cement board
To make the cutouts for the plumbing I used a carbide tip meant for cement board with my handy dandy cut-out tool
I wrapped up the shower surround on Saturday and moved on to the rest of the room on Sunday. I'm planning on tiling part way up the wall in the main area of the bathroom. Because that area is outside of the wet zone of the shower I could use drywall under that tile but since I had extra panels of cement board on hand I decided to use cement board.
With the cement board all installed I was ready to finish closing up the walls with drywall. I had only one problem: no 1/2" drywall at home. Normally I would sweet talk Frank into going with me to Lowe's with his truck but he had left for a work trip at noon so I was left to my own devices on this one.
I took measurements of the cuts I would need, packed my T-square, measuring tape and utility knife in my car and headed off to Lowe's. I bought the two sheets of drywall I needed, rolled it out to the parking lot and then just cut the sheets down to what I needed in the parking lot. With my back seats folded down it barely fit but I got it all in.
I could have waited until Frank came home but he won't be back until Friday night and I didn't want to wait. Plus, being stubborn and independent is part of my charm, right?
By Sunday evening I had all of the drywall on the walls and everything closed up. I was pretty exhausted from the weekend (cement board is heavy!) but so glad that the bathroom is starting to look like a room. Next up is mudding and taping the drywall!

Sorry I am a little late to this blog entry... It is amazing how far you have come with this project, especially since you have been travelling for work and not feeling 100%. I had a giggle about your wall board being cut in the parking lot, I did something similar once, I took the item out of the packaging so it would fit into the truck/car and I got quite a few stares. No worries folks, I did take all the packaging back into the store for recycling. Leave it to us women to find a way when there is a will :-)
Wohoo great job!! I loved the passion you invested in it to make it look perfect. I am gathering as much information as possible about drywall insulation and good quality drywall products so that one day, I can get it done with perfection at my home sans any external help!

Shower walls must be backed with a waterproof backing board. Drywall is not an acceptable backer board. Even moisture-resistant drywall (green or blue varieties) will not hold up in showers. Use a true cement backer board, or try a shower backer board kit, but this Blog amaze me so much as you are using drywall in the bathroom. Please update me with results as soon as you tried this coz I'm looking forward to copy your ways (haha) Good job!! and God Bless!!
