Drain Backed Up After a Shower and Laundry Ran Together: Safe Checks
If a drain backs up when a shower and washing machine discharge at the same time, stop all water use immediately, including the shower, washing machine, toilets, sinks, and dishwasher. Keep children and pets away from wastewater, avoid contact with sewage, and switch off power to a wet area only from a dry, safe location.

Drain Backed Up and the House Smells Like Sewage After Closing
A backed-up drain with a sewage smell means wastewater or sewer gas may be unable to leave normally. Stop adding water until you know whether the problem is limited to one fixture or affects several drains.

Drain backed up: What to check before calling a plumber
Stop adding water and first identify whether one fixture is blocked or several fixtures are backing up together. A single sink, tub, or shower that is slow or standing full usually points to a local trap or branch restriction; backup at more than one fixture, a low floor drain, or dirty water coming up when another fixture runs points farther downstream toward the building drain, private lateral, septic system, or public sewer.

Pipe Backed Up: Reduce Water Use and Separate a Local Blockage from a Sewer Problem
When a pipe backs up, stop adding water first. Do not flush toilets, run the dishwasher or washing machine, shower, or keep filling a sink while the route is unknown.

Shower Backed Up After Shower and Laundry Ran Together
A shower that backs up after the shower and washing machine discharge at the same time usually means the drainage path cannot accept that combined flow somewhere downstream of the shower, but the exact point may be a shower trap, a shared bathroom or laundry branch, the building drain, or the sewer connection. Stop both water uses and do not add more water to test it.

Shower Backed Up: Clear the Waste Safely and Tell a Local Blockage from a Shared Drain
Stop using the shower so the tray does not overflow, then determine whether only the shower is affected. Remove the drain cover and pull out hair or debris that is plainly accessible, use a correctly sized plunger with enough water to seal around it, and test the drain in short, controlled attempts.
