Rough Plumbing

There are three common options for water supply pipes in a house: PEX (Cross-linked Polyethylene), Copper and CPVC. All three options have pros and cons; there is much debate over which is best or worst. Consult with your Architect, Builder and Plumber before making a decision. PVC is used for waste pipes in most homes without much debate so alternatives are not listed here. Black iron is used for gas pipes in most homes without much debate so alternatives are not listed here.

            __ PEX                                     __ Copper                               __ CPVC

Bathroom Shower Base

The floor of your shower deserves some thought and research. If you want a stylish, upscale shower floor, you will likely consider a site built shower pan because it gives you the greatest flexibility with regard to size, shape, color and patterns. There are two significant drawbacks: first, it is the most expensive option, and second, it can be more susceptible to leaking. There are several different methods to waterproof a site built shower pan. Whichever waterproofing option you select, be sure to conduct a flood test prior to installing the ceramic tile on top of it.

__ Fiberglass   __ Acrylic        __ Marble       __ Solid surface          __ Site built shower pan


If opting for a site built shower pan, select the water proofing material:

Once the rough framing is complete, work can begin on the rough plumbing. Rough plumbing and plumbing fixtures are very expensive to alter once installed, so the majority of time you spend on the plumbing phase should be on management as opposed to inspection. Confirm your plumbing selections prior to meeting with your plumber.


Review Scope Of Work with Plumber

  1. Verify any existing plumbing items or systems that need to be removed or replaced.
  2. Conduct a thorough “walk-thru” with your plumber and mark centerlines of sinks and toilets on the rough framing.
  3. Mark centerline and height of shower heads and shower controls for plumber. If you don’t, your plumber’s preferred location may not match yours.
  4. Make sure there is enough room between rough plumbing for sinks and adjacent cabinet drawers.
  5. Verify location of recessed shower box and grab bars (if applicable) and coordinate with location of shower controls.
  6. Verify sufficient floor cavity depth for trap.
  7. Verify location of washer wall box and floor drain at the clothes washer.
  8. Verify location of gas supply system to the following appliances and/or equipment: clothes dryer, oven/range, hot water heater & furnace.
  9. Verify location of water line to new refrigerator.
  10. Verify location of underground storm drains (to connect to downspouts).
  11. Verify location of hose bib.


Organization of Materials & Delivery Dates

  1. Confirm who is responsible for ordering, purchasing and delivering plumbing fixtures and accessories. Some of the accessories may be needed at time of rough plumbing, especially at showers. By giving your plumber these responsibilities, you can save yourself several trips to the vendor.
  2. Confirm delivery date and safe location to store plumbing fixtures, including tubs, shower enclosures, toilets, sinks and faucets. Some of these items are large, taking up a significant amount of space and some of these items are small and can be lost easily.


Inspect For Correct Installation

  1. Verify sinks, tubs, showers and clothes washers have vents that connect to a roof vent.
  2. Verify round insulation is installed at hot water pipes.
  3. Confirm that all rough plumbing is completed prior to installation of insulation and drywall.
  4. Check that sealant is installed at faucets and escutcheons.
  5. Check that all fixtures work: flush toilets, run hot and cold water at faucets.
  6. Check that water is hooked up to refrigerator.
  7. Check that dishwasher functions properly.
  8. Check that drains work.
  9. Detect any leaking and report any problems to plumber.
  10. Perform flood test at shower base.
