There are a few additional subtle signs that could hint at a leak, especially if the bathroom is near carpeted areas or if tiles have started loosening.

• Carpet: Gently pull back a corner near the bathroom if possible. Inspect the carpet pad and the wooden tack strips underneath for staining, mold growth, or crumbling wood.
• Tiles: Tap on shower tiles lightly with a knuckle. Loose, hollow-sounding, or visibly cracked tiles can indicate underlying moisture damage.
• Baseboards and Trim: Check for swelling, softness, or peeling paint, particularly along the floor or tub edges.

If you uncover any of these problems, it’s better to stop and consult a professional. If no signs are found and surfaces feel dry and stable, you’re ready to move forward with safe DIY cleaning.
