 add shower on slab
Author: Anonymous User

I need to add a shower in my half bath/laundry room that is on a slab floor. How do I do it without trenching through the concrete? Can I use a sewer ejection pump and pump into the sink or washing machine drain? What kind of shower base do I need? How much flow can an ejection pump handle?

In order to pump the drain you will need to put in a lift can and pump. so before doing all that work i would suggest cutting the floor and cutting a wye into the 2" drain under the floor. I think you will be more satisfied with the end results. Just my opinion

The pump should have no trouble draining a shower. Remember to design the pump closet so there's clearance for soundproofing fiberglass insulation, and some airspace so the motor doesn't overheat.

If you are going to have to break concrete for the pump receiver, do the job right and just install the shower drain to the sewer system.
