What this guide helps you decide
Decide which shower features you actually want: fixed head, handheld, body sprays, tub spout, diverter or thermostatic control. Each has different valve and piping needs.
Start with the existing conditions
Confirm the trim and rough-in valve are from compatible manufacturer families and that service parts will remain accessible. A finish color alone does not tell you which valve fits.
Plan materials, layout and access
Lay out heights with the users of the shower in mind and check the niche, seat and glass-door locations at the same time. Verify required clearances against product instructions.
Check the result and plan follow-up
Approve the final fixture list before plumbing rough-in and waterproofing. Photograph valve locations and keep model numbers for future cartridge replacement.
Common mistakes to avoid
- Ordering trim without checking the rough-in valve
- Moving a valve after waterproofing
- Placing controls where the user must stand under cold water
Tony’s Pro Tip
Tape the proposed fixture locations to the wall and stand in the unfinished shower before deciding.
Should you DIY or hire help?
Hire a plumber or remodeler for new valves, moved supply lines, inaccessible mixing valves or major shower-layout changes.
