A grate catches larger debris at the shower floor. Hair and soap residue can restrict its openings enough to slow water even when the pipe below is clear. If water still pools after the accessible surface is clear, the restriction may lie deeper.
Start with what you can see
With the shower off, look for hair or residue covering the openings. Follow the manufacturer’s instructions for any removable cover. Avoid prying up a fixed grate or disturbing the seal around a tiled drain.
Report what happens after normal use
Note whether water drains away shortly after the shower stops and whether any nearby fixture drains slowly too. If pooling continues or returns quickly, share the grate type and prior cleaning history with the plumber so they can assess the trap and branch line.
