Materials you will need for a concrete bathroom shower
Step #1: Let it begin!
After our Shower Demo
We pulled out the shower in an earlier post you can check out the details for that here.
Step #2: Drop the tub
I found this standard size tub 32″ x “60 off of Craigslist for $40. It’s super deep and was in excellent shape so we snatched it.
Step #3: Put up cement board
My wife originally wanted the whole entire shower and bath to be cement but as this was my first-time attempt at a cement bathroom I decided on buying a fiberglass tub with everything else cement.
I built a little support/sidewall out of 2×4’s to encase the tub and framed out a small niche. Then attached cement board to all the walls of the shower and the little sidewall.
Step #4: Seal seams
I then put fiberglass mesh on all the seams.
I then patched the seams to seal them with Quickcrete hydraulic waterproof cement.
Step #5: Apply Red Guard
Applied RedGuard. You can apply this with a roller, sponge or brush. I like how it went on with a sponge the best.
Step #6: Appy Ardex
Next, I mixed Ardex CP as instructed on the bag and then applied to all the RedGuard walls and side wall.
My wife wanted everything surrounding the toilet to be concrete because of all the boys with bad aim so I also applied the concrete to the wall and the cabinet side that was next to the toilet.
That dried for a day and then we moved on to the next step.
Step #7: Ardex TWP and sand
We then mixed the Ardex TWP to a pudding consistency and applied with a trowel. TIP: the mix dries really fast so don’t mix much more than a quart at a time. I applied two coats. It just needs to have a smooth consistency.
Once that dried, I did a light sanding.
I wanted to make sure it was sealed and really shiny so I rolled on several coats (probably 13) of high gloss Valspar water sealer. Add replaced our hardware.
My wife was super happy how our concrete bathroom shower turned out. She is in love with how simple it was, how clean and industrial, yet elegant it looks.
