Ensuite
Ensuites share a wet wall. One shower can write on two ceilings.
A small ensuite back-to-back with another ensuite is a classic path. The grout conversation and the valve conversation get mixed. Separate them.
Which shower was running, and when did the stain appear.
That sentence is the investigation’s start.
Do not recaulk both ensuites as a plan.
You can seal over a valve leak.
Ask for both suites on one appointment.
Back-to-back walls are a waste of two visits.
Questions people ask
Is this always the shower pan?
No. Valves, supplies, and wastes share that wall.
Can we just renovate the ensuite?
Renovation without a source note is how the new tile stains.
