Day 13 – Shhhhh

When changes are made to an old house using new materials, what is available and affordable, it can radically change the way the house is experienced. This is especially noticeable when it comes to sound and how sound is transmitted into adjacent rooms.


Old materials such as plaster and cast iron pipes are great at stopping sound. But the new materials that replace them gypsum board and PVC do nothing to stop sound. So what to do when remodeling a bathroom. Fortunately, I have a contractor who has a number of tricks up his sleeve. His tricks will add to the cost of my project, but it is worth not hearing the toilet flush or my daughter singing in the shower.


The sound solution for the bathroom walls is two part Roxul SafeN’Sound Insulation and Quiet Rock. The Roxul goes into all the cavities, except where there is existing knob and tub, the Quite Rock goes over the studs, it is used in place of standard 1/2″ drywall board. And BTW it costs about 5xs as much. Fortunately, the room is small and when you come to visit me, rest assured what happens in my bathroom, stays in my bathroom.

  1. Your photos and notes anticipate what we will see in 2 weeks with our new, second bath. My husband studied the photos and notes. He asked about the red surface. Functional?


    1. It is red guard. The tiler put it on surfaces as a water sealant. When cement board is used as the tile backer (vs the Wedi) red guard is used on all surfaces where the tile will be laid and it serves as the water barrier. That is one of the things that is so great about products like Wedi, the whole material is waterproof, not just the surface they put on top.
