My bathroom has basic bathroom waste facilities, i.e. a toilet and shower drains. However, I want to change it all, i.e. rearrange the pieces. The floor is solid concrete and the main sewer pipe is, i would say, 2-3 ft below. This is a federal style city row-house, all-brick, built 1909 in Washington, D.C., to help with framing a reference.
When it comes to breaking the concrete floor in the bathroom, I was thinking of using a 1" SDS rotary hammer, such as this:
with some masonry chisel bits. Is this the right tool? I am sceptical to use a jackhammer because I fear it is not precise enough and it might cause unwanted cracks outside the bathroom frame.
Also, any other insight would be much appreciated from anyone who has related experience ...
