I'd like to make one of my bathrooms that one special place where a guest can go about their business in peace. Essentially, I am going to be soundproofing/insulating my entire bathroom, but the doors are an area I need a little help with.
Right now, both doors are light, hollow doors with about an inch and a half of space beneath them. The first order of business is to get heavier, denser doors and also lessen the space between the bottom of the door and the floor. That I can handle, but there's inevitably still going to be a small space left over and I want to make sure even that is sealed up.
I conceptualize a hard, rubber-like strip that is installed on the floor beneath the door. Alongside the bottom of the door is another strip that butts up against the bottom strip, creating a tight seal. I don't know if something like this exists on the mainstream market and, if it does, what it's even called so that I can look for it at my local hardware store.
Perhaps you could offer your own ideas as to how I can soundproof my doors much more efficiently.
