Plumbing a Basement Bathroom
Cutting through the slab is grunt work of the highest order, but a relatively easy way to get an extra bath.
Adding a basement bathroom is just like adding a bath anywhere else in the house—except for cutting through the basement’s concrete-slab floor. Rhode Island contractor and Fine Homebuilding contributing editor Mike Guertin outlines his strategy for adding a basement bath, starting with planning the drain layout. This crucial step ensures that plumbing is located so that wastewater flows downhill to a tank; from there, it is pumped to the main waste line and out of the house. It’s also important to tie in vent lines for the basement fixtures.
