Remodeling and Bathroom Installations

We have compiled a list of recommendations and tips when remodeling or installing new bathrooms.

  • When you have a 3″ pipe in a wall build a 2×6 wall.
  • We advise using copper water piping.
  • If replacing your water lines with PEX, using 1″ for the main run, to risers and to the water heater branch will supply more volume for using multiple fixtures.
  • When installing a shower use a 36″x36″, if possible, this is a comfortable minimum size.
  • Always use a pressure balanced tub & shower/shower faucet.
  • When ordering a tub. Stand in front facing it like your getting ready to step in, the side the drain is on will determine if it is a right or left-handed tub.
  • Know the specs of your cabinets before roughing-in drain and water piping or they may interfere with drawers or shelves.
  • A normal shower arm rough in is 78″ high. If possible an 81″-83″ rough in will accommodate a taller person.
  • When roughing in for a toilet, minimum code is 15″ from center of toilet to edge of adjacent fixture or wall, leaving a 30″ opening. Roughing it 18″ from center will give you a more comfortable space. Measure 12-½” from center of drainpipe to back stud wall, if your using tile add the extra wall board and tile thickness when roughing.
  • When installing a shower base, set it in mortar or foam. It will stop the flexing and help prevent the shower from breaking if you drop something.
  • When remodeling, if you have old galvanized water piping in a ceiling or wall that will be dry walled, paneled, or tiled over, replace the piping before you begin. Nothing is more depressing than needing to replace them after your remodel job is complete. If the piping is over 40 years old, they will normally have a lot of rust and should be replaced anyway.

    Your information that using 1-inch pipes for the main run of a water line will supply more volume so you can have multiple water fixtures sounds really technical. I initially read through your article so I could learn recommendations for replacing a shower in my master bathroom or fix the toilet plumbing. Now, though, I think I will call a professional plumber to help with the renovations.

    I’m planning on replacing my toilet and sink in my bathroom during my big bathroom remodel. It makes sense that I might want to get a professional to help me out with this. They would be able to help me figure out what the specs of my plumbing system are.
