PEX Rough-In Work for Louisville Kitchens, Baths and Laundry Rooms

Bathroom Rough-In, Fixture by Fixture

Fixture placement is decided before we start, so bring the spec sheets for your valve, faucets and toilet to the planning visit.

Shower and tub valves

The valve body is the heart of the shower. We mount it on solid blocking at the correct depth for the trim you have chosen, connect PEX to the hot and cold inlets with the adapters that valve requires and run a rigid drop to the showerhead. A loose valve or a flexible line to the head causes rattling and makes the trim hard to fit later.

Vanity and toilet

Supply stubs come through the wall at heights that clear the vanity drawers and line up with the toilet's fill valve. We use drop-ear elbows or stub-out brackets anchored to framing so the pipe does not wiggle when someone turns a stop valve.

Kitchen and Laundry Details That Get Overlooked

Moving a laundry upstairs or relocating a sink to an island is easier with PEX because the tubing can follow joists and avoid a lot of extra fittings. Our Louisville bath and kitchen remodeling team can coordinate the whole project if you want one company handling the plumbing side.

• A dedicated cold line and valve for the refrigerator ice maker and water dispenser
• Separate stops for the dishwasher so it can be serviced without shutting off the sink
• A pot filler line anchored securely behind the range wall
• A recessed washer box with quarter-turn valves and a built-in drain connection
• Room in the sink base for a water filter or under-sink water heater if planned
• Hammer arrestors where quick-closing appliance valves can cause banging

Protecting PEX Inside the Walls

Once drywall goes up, any mistakes are hidden. We take a few steps to prevent future damage: steel nail plates wherever tubing passes close to the face of a stud, sleeves through holes in metal framing, gentle sweeps instead of tight bends and supports at regular spacing. Tubing is kept away from recessed light housings and bath fan ducts.

PEX is naturally quieter than copper, and adding insulation around lines in shared walls cuts flow noise further, which is welcome when a bathroom backs up to a bedroom.

Pressure Testing Before the Walls Close

Every rough-in is pressure tested before insulation and drywall. We cap the stubs, pressurize the system and watch the gauge for a set period to confirm there are no leaks. Only then do we tell your contractor the walls are ready. After the room is finished, we return to set fixtures, connect supplies and do a final quality inspection.

For faucet selection and setting, our faucet installation service can help, and new toilets are handled through our toilet installation team.

When the Old Supply Lines Should Go Too

In many Louisville homes, the rooms being remodeled are fed by older galvanized or copper lines in the basement. Connecting brand-new PEX to tired pipe can leave you with a beautiful room and the same old pressure problems. We check the feed lines during the free estimate and let you know if extending the work makes sense. Once you approve the specifications, we schedule rough-in around your contractor's timeline.
