Slow-draining showers and what is in the trap
The short answer
Shower wastes clog with hair bound in soap residue, usually within the trap directly under the outlet.
What to check
- Most shower traps have a removable insert designed to be lifted and cleaned
- knowing yours can be opened saves a call-out.
- A shower that has always drained slowly may
- have inadequate fall rather than a blockage.
Your questions answered
Are hair catchers worth it?
Yes, they prevent the most common cause almost entirely.
Why does it smell?
Usually residue in the trap, or a dried-out trap seal on a rarely used shower.
Not sure which option suits your property?
Most of these decisions come down to what is behind the wall and under the floor. A site visit settles it quickly.
