I still do not have plumbing that drains for my washer.

Here's why...WATERPlanning - in many states you cannot put a water well within 150 - 300 feet of a septic system or it's drain field.  

We always install laundry on the lowest floor in the unit (several of our units are 2-story) and install an overflow pan with floor drain under the laundry units themselves.We have winter here which comes with a month or more of temperatures in the -20 to -30 range.  

Hey DonaldThis is from an experienced carpenter the base looks good from the photo pop off the countertop and replace it with a sheet of 3/4" plywood cut two drain holes for the drain of your new sink bowls countertop flush mount cover countertop with tile $100-150 for sink bowls & plumbing hardware@menards $75 for wood, tile and grout.

It NEEDS air to drain right. 

It would require bringing in an architect and structural engineer to draw the solution out and we would have to relocate the furnace that currently sits exactly where the rear entry would move to.The other solution is to put in a new drain stack, plumbing and gas lines entirely to where the bedroom would relocate and open the front of the house up again.

If it's hot water, you need to say whether you have baseboard or standing radiators. radiators need the air bled to allow water to move, baseboard often doesn't have bleeds and the line needs the air flushed out by opening the drains at the boiler.

Second is plumbing issues with drains connected to showers.

You can even do a swanky stackable W/D unit in the bathroom with a drain in-case the entire thing floods at one point.

Tenant management drains soo much time.
