Water on the bathroom floor after a shower often comes from splashing past a curtain or door, or from worn caulk around the tub or shower. It can also come from a plumbing source, such as a leaking shower valve, tub spout, drain connection or a crack in the tub or shower base.
Because so many things can leave water on the floor, the first step is to figure out where it starts. A little water from splashing is easy to fix. Water that comes from hidden plumbing can damage the floor or the ceiling below if it is not found.
Simple Sources to Rule Out First
Some common causes have nothing to do with the pipes:
- a shower curtain that is too short or sits outside the tub
- a shower door with worn seals or a gap at the bottom
- water running off the body or a towel while stepping out
- a shower head aimed toward the opening
Watch where the water collects. If it is always right outside the opening, splashing may be the cause. If it shows up along the base of the tub, near the toilet or in a corner, a closer look may be needed.
Plumbing Sources That May Be Involved
Some causes are part of the bathroom plumbing:
- a tub spout or shower valve that leaks behind the wall
- a loose or worn connection at the tub or shower drain
- a leak at the overflow plate on a bathtub
- a crack in the tub, shower pan or base
These may only leak while the shower is running or when the tub is filled. Water from them can move under the tub or flooring before it appears, so the wet spot may be some distance from the source.
Caulk and Grout Problems
Worn or missing caulk where the tub meets the wall or floor can let water slip through. Cracked grout can also let water reach the wall behind the tile. These are not plumbing parts, but they often show up alongside plumbing questions. Our work focuses on the plumbing side, so tile or wall repairs may need a different trade.
Signs That Call for a Closer Look
It may be time to have the bathroom plumbing checked if you notice:
- water on the floor even when no one splashed
- soft, loose or stained flooring near the tub or toilet
- a stain on the ceiling below the bathroom
- musty smells that do not go away
In a Bronx apartment building, a leak from one bathroom may show up in the unit below. Renters should report repeated water on the floor to the super or landlord so the source can be found early.
Keep the floor dry to prevent slips while you sort out the cause, and avoid using wet electrical items in the area.
