The customer reports a slow-draining shower that, while still functional, is not emptying at its normal pace. This issue is entirely isolated to the single shower fixture, as the nearby toilet and all other household drains are operating correctly. The localized nature of the sluggish flow strongly suggests a superficial obstruction, such as a localized accumulation of hair and soap scum, rather than a deeper systemic plumbing problem. To resolve the issue and restore optimal drainage, three progressive service actions are recommended. First, a targeted shower drain cleaning should be performed to pull out shallow debris and clear typical hair blockages. If the slow flow persists, a shower drain line inspection will be necessary to evaluate the accessible piping for a deeper or more stubborn restriction. Finally, a thorough drain flow testing will be conducted by running water through the fixture post-service to confirm normal flow capacity and ensure no further cleaning is required.
