Shower Installation (Remodel)
Shower installation during a remodel means setting the valve, shower pan or mortar base, and drain to match your new tile and layout — then trimming it out after finishes. FlowFast Plumbing connects you with an independent local plumber who gets the valve depth, waterproofing coordination, and drain slope right before tile, and sets the trim after.

View all Remodel Plumbing servicesA remodel shower is unforgiving of small errors. The valve body must sit at exactly the right depth for the finished tile — too deep and the trim plate gaps, too shallow and the handle binds. The pan or base needs a precise slope to the drain with waterproofing lapping correctly over it, and the drain assembly must align with the tile layout so it does not land awkwardly on a grout line. Because all of this disappears behind tile and mortar, the plumbing has to be perfect before the tile setter ever arrives.
Through FlowFast Plumbing, an independent local plumber installs the shower valve body, shower arm stub-out, pan or base drain, and any body-spray or rain-head rough-ins to your tile plan's exact measurements. The pro coordinates with your tile contractor on waterproofing sequencing and curb or curbless details, pressure-tests the valve before close-up, and flood-tests the pan where the design calls for it. After tile and grout are done, the pro returns to set the trim kit, shower head, and handle — then runs the shower to verify drainage, temperature control, and zero leaks.
Warning signs
Signs you need this service
- Your remodel converts a tub to a shower or reconfigures the shower footprint, requiring a new valve location, drain position, and pan.
- You are upgrading to a rain head, body sprays, or a thermostatic valve that needs new rough-in piping the old shower never had.
- The existing shower valve is outdated, the pan leaks, or the drain location fights the new tile layout you have chosen.
- Your tile contractor is scheduled and needs the valve set, the pan installed, and plumbing inspected before waterproofing begins this week.
What to expect
The process, step by step
Measurement: the pro works from your tile plan to position the valve at finished-wall depth and the drain to suit the layout.
Rough-in: the valve body, shower arm, pan drain, and any extra spray rough-ins are installed and pressure-tested before walls close up.
Coordination: the pro aligns with the tile contractor on waterproofing, curb details, and flood-testing the pan where the design requires it.
Trim-out: after tile is complete, the pro sets the trim kit, head, and handle, then tests flow, temperature, drainage, and leaks.
Prevention
How to avoid this problem
- Choose the valve and trim before rough-in so the body matches the exact trim kit going on the finished wall.
- Flood-test the shower pan before tile — finding a pan leak after grout is a tear-out, not a repair.
- Confirm the water heater and supply lines can feed a multi-head shower before the design depends on that flow.
