Copper to ABS Shower Drain Upgrade in Post Falls

A bathroom remodel often reveals plumbing that has been hidden for decades. At this Post Falls home, the tile crew was preparing to build a new shower, but first the existing copper shower drain needed to be removed and updated.

With the floor already opened up, this was the right time to replace the older drain assembly rather than build a brand new tile shower over aging plumbing.

From old copper to a new ABS drain

The before photo shows the original copper shower trap and drain assembly after it was removed. The replacement uses ABS drainage piping, with the new riser positioned through the floor for the upcoming shower installation.

This type of plumbing preparation is common during bathroom fixture and shower upgrades. Getting the underground or concealed plumbing right first means the finished work can move forward without having to reopen the floor later.

Why do this before the tile goes in?

Once a tile shower is completed, the drain becomes much more difficult to access. Waterproofing, mortar, tile, and the finished shower base can all be affected if plumbing underneath needs to be corrected later.

Taking care of the drain while everything is exposed provides an opportunity to inspect the existing piping, remove older components, and make sure the new connection is ready for the next stage of the remodel.

A small part of the remodel that matters a lot

The shower drain does not get much attention once a bathroom is finished, but its placement and installation are critical. The trap and piping need to carry water away reliably while fitting correctly with the new shower system above.

• The existing copper shower drain and trap were removed.
• New ABS drainage piping was installed.
• The drain riser was positioned for the new tile shower.
• The plumbing was prepared so the tile crew could continue the project.

For homeowners planning renovations in Post Falls, involving a plumber before the finished surfaces go in can make the project much smoother and help avoid expensive changes later.

Plumbing and tile need to work together

Remodel projects often involve several trades working in sequence. The plumber needs to leave the drain in the correct location and condition so the tile installer can build the shower around it. Good coordination at this stage helps keep the project moving and gives everyone a better foundation to work from.
