As much as he dreaded it, John rented a jackhammer and jackhammered a portion of the garage floor. All in preparation for the new and improved plumbing.
As previously mentioned, John is redoing the plumbing because we will be relocating the laundry to the garage. See renovation plans here.
And while he's at it, since he's redoing all the plumbing anyway, he is going to add a small garage bathroom.
When I was growing up, we had a small 1/2 bath in our garage and it proved invaluable for those days when you were working outside and didn't want to bring mud and dirt inside when going to the bathroom.
The picture above isn't "drawn" to scale. It just shows a rough placement of the garage's new features.
