Fix 2 of 6
Add a bath off the main bedroom
Many ranch houses have one hall bath and a main bedroom with none. A closet, a corner of the room or a shallow wall can become a bath of your own.
The plumbing decides the plan. In a slab house the drain has to be cut through the concrete, so the best spot is as close to the existing plumbing as the layout allows. We draw two or three options and pick one with you. Then we trench the slab, rough in the pipes and wires, waterproof the shower, set the tile, and install the vanity and a fan that vents outside through the roof.
What the job includes
A layout drawing and the City of Phoenix permit
The slab cut, trenched and patched
Supply and drain lines by a licensed plumber
A waterproofed walk-in shower, tiled
A vanity, a mirror and a fan vented outside

What changes the cost
What moves the cost of a new bath
No figures here: the number comes after the walk-through. These four things decide it.
How far from the plumbing
Every extra foot of trench through the slab adds work. A bath back to back with the hall bath is the simplest.
Size of the shower and the tile
A bigger shower, a bench or niches, and small or patterned tile take more time and more material.
Borrowing space
Taking a closet is simple. Moving a wall or part of a bedroom adds framing, wiring and a new ceiling line.
Fixtures and glass
Faucets, vanity, mirror and a glass door sit as allowances on the estimate until you choose them.

Questions
Before you pick a fix
Where does the drain go in a house on a slab?
Through the slab. We locate the existing lines first so the cut is as short as it can be, trench the concrete, set the new drain and vent lines, and patch it after the city inspects the rough plumbing.
Do I need a permit for a new bath?
Yes. A new bath adds plumbing, wiring and a vented fan, and the City of Phoenix inspects the rough work before it is covered. We apply and schedule the inspections.
Do you pick the tile for us?
You choose. We bring samples to the walk-through and set an allowance for tile on the estimate, so you know what the choice does to the total.
Have a closet in mind?
Text a photo of the main bedroom and the closet. We tell you how close the plumbing is.
