Concealed shower systems are specified for their minimal, architectural look. The success of the installation depends on correct rough-in, correct depth, and a clear outlet plan.
Before you start: define the outlet plan
- Overhead (rain) shower
- Hand shower
- Body jets (optional)
- Tub spout (optional)
Confirm whether you want simultaneous operation (two outlets at once) or diverted operation (one at a time).
Rough-in coordination checklist
- Wall build-up: substrate + waterproofing + tile thickness
- Minimum cavity depth: valve body + tolerances
- Trim alignment: final faceplate should sit flush and level
- Pipe routing: avoid tight bends that reduce flow
- Access: ensure future service access to cartridges/diverters
Common mistakes
- Valve body set too deep or too shallow (trim won’t fit correctly)
- Diverter outlet mapping not documented (confusing controls)
- Flow constraints ignored (weak performance on rain head)
If you’re delivering multiple bathrooms (apartments or hotels), treat the rough-in as a repeatable system: one standard detail, one set of tolerances, and one commissioning checklist.
