I am creeping along on my bathroom remodel. I am still working on rebuilding my shower and it is slowly actually starting to look like a shower again. After leak testing the shower pan liner, it was time to hang the cement board on the walls since I left it like this:
And once the mortar was complete on the shower and knee walls:
I also used mortar to repair the damage to the green board behind my roman tub. If this were a "regular" tub I would have pulled all the green board out (since it is NOT good to use on a tub) and replace it with cement board. However, since this is a roman tub and is so deep, and it is so infrequent that water comes in contact with the walls around it, I decided to forgo the time and expense of replacing it. If you were to install a hand held sprayer or anything else that could possibly lend itself to excessive splashing, you would definitely want to use cement board:
Once the walls were repaired, it was time to finally finish the shower pan. I talked a little bit about how you build a shower pan correctly in my last post. This was just the final step. I used this mud calculator to figure out exactly how much deck mud I was going to need for the final pan. It turns out I ended up needing 40 pounds of portland cement and 200 pounds of sand.
Needless to say I needed help with this step because my mixing pan wasn't large enough to do a batch that large. I had to mix three smaller batches. Because the set time was under an hour for portland cement, I had hubs make the mix, while I spent the hour packing and leveling the deck.
I didn't get a lot of pictures of this process, but when all was said and done, this is what my final shower pan looked like:
Cement board tape: $6.41
All Purpose Sand: $5.64
Portland Cement: $4.34
