What the inspector means
Deflection or softness in a bathroom floor often points to moisture damage around a toilet, tub, shower, vanity, or plumbing penetration.
Common causes
- Toilet seal leak
- Tub/shower leakage
- Failed waterproofing
- Plumbing leak
What the repair usually looks like
Correct the leak source, remove enough finish flooring to expose sound material, replace or reinforce damaged subfloor, then restore the finish floor.
Who should handle it
The project can involve plumbing, carpentry, tile/flooring, and sometimes moisture remediation.
Planning cost
$800-$3,500+ for localized subfloor/floor restoration; larger wet areas or tile work increase the scope.
Access, materials, hidden damage, minimum charges, permits, and existing conditions can change actual cost. Use this range for planning, not as a quote.
