Some tiled showers use a mortar bed over a waterproof liner. Small weep passages in a compatible drain let water that reaches the liner enter the waste pipe. Other shower assemblies use a different waterproofing and drain design, so the drain type matters before anyone opens the floor.
Describe what stays wet
Note whether grout near the drain remains dark long after use, whether the bathroom has a persistent odor, or whether water is visible below the shower. These signs can have several causes. Photograph the floor and keep any installation details from the remodel.
Ask how the assembly will be identified
A plumber or shower repair contractor can check the drain type, accessible piping, and signs of moisture before recommending work. Ask how they will protect the waterproofing and what needs to be inspected before a repair can be scoped.
