Concrete Bathroom 101 Part 2

This week brings great progress on the dual concrete bathroom project.  We removed a total of 70 contractor bags of concrete walls and floor fill, that’s a grand total 3500 lbs of material.  The joist work was as expected (crooked and warped) requiring every joist to be sistered prior to the subfloor installation.  As an added measure for noise reduction all of the walls were foam core and fiberglass insulated before the closed up. Insulation was even added around the new PVC waste lines to silence audible water flow.  Being quite is about the only advantage to residential cast-iron plumbing (in my opinion).  We are gearing up for tile installation, but as we do…. let these photos be a reminder, preparation is EVERYTHING!  Thanks for looking. Hall bath, tub set

Good bye closet, hello big shower stall!

Big R-factor in a small space.

Concrete Bathrooms 101

If you are a homeowner in the Washington Dc area chances are good that your home was built in a time before drywall, plywood, and definitely before tile was set on products like hardibacker and durock.  So what did the old school builders of past install that pink and green tile to? CONCRETE, that’s what, and a lot of it.  On average a pre 1970 bathroom in our area is constructed from about ¾ of a ton of the heaviest, dustiest and potentially home damaging concrete around.  Prior to USG Concrete’s invention of durock in 1970, home-builders would simply fill up lath and joist cavities with concrete to have an acceptable surface to tile upon.  Concrete so difficult to remove that in the early 50’s companies such as Sears created tile-over-tile cover up kits for homeowners wanting to remodel their outdated spaces.  These kits came in a variety of colors that quickly became outdated, pink and green being among my favorite.


Follow along as I document Denny and Gardner’s latest concrete bath renovation.  With over 150 concrete bathroom remodels under our belt in the past decade, D and G remains the undisputed champ in concrete bathroom renovation.
