Before fixing the issue, it helps to understand the cause. Common reasons for a clogged drain in tub include:
Hair buildup
Soap scum and greasy residue
Hard water mineral deposits
Sand or dirt from outdoor activities
Tree root invasion in older pipes
Drain slope and clay-heavy soil pressure
If your bathtub water isn’t draining or is draining slowly, chances are there’s a blockage forming, either near the surface or deeper within your drainage line. In many cases, the bathtub drain clog can also affect nearby bathroom sinks and shower drains.
Many clogs form when soap scum and hair combine inside the shower drain or overflow plate. This can block both bathroom sinks and tubs, especially when drains haven’t been cleaned in months. Homeowners may also find standing water in the tub, which is a clear sign of blockage.
How St. Catharines Weather and Soil Conditions Contribute to Bathtub Drain Clogs
Clay-Heavy Soil Slows Drainage Flow
According to Agriculture and Agri-Food Canada, St. Catharines and the surrounding Niagara Region are dominated by clay-rich soils (Soil Survey of Niagara Region). These soils absorb and retain water, putting excess pressure on underground pipes and slowing water flow. Over time, this can contribute to frequent drain clogs and even minor pipe damage, especially in older plumbing systems.

High Precipitation Levels Lead to Saturation
Data from Environment and Climate Change Canada shows that St. Catharines receives over 1,000 mm of precipitation annually (Adjusted Precipitation Dataset). This consistent moisture can saturate the soil and flood external drain lines, increasing the chances of a clogged drain in bathtub, especially during the rainy season or spring thaw.

Freeze-Thaw Cycles Stress Pipes
Frequent freeze-thaw cycles in winter cause water in the soil to expand and contract, leading to pipe shifts, cracks, or loosening. These issues can result in long-term drain problems that manifest as recurring clogs.

DIY Clogged Bathtub Drain Solutions You Can Try Today
Boiling Water Method
Pour boiling hot water slowly into the bathtub drain to melt away grease and soap buildup. Works best on light clogs.
Baking Soda & Vinegar
Pour ½ cup baking soda, then 1 cup white vinegar into the tub drain. Wait 15–20 minutes. Flush with hot water.
For stronger buildup, let the mixture sit longer before rinsing.
Plunger Technique
Place a wet cloth over the overflow drain. Use a toilet plunger to pump the main drain and release pressure clogs.
Drain Snake or Zip-It Tool
Tools like a drain snake, drain claw, or plumber’s snake can pull out deep clogs that plungers can’t reach.
Enzyme Drain Cleaners
Bio-enzyme products break down organic buildup slowly. Good for monthly maintenance.
Important: If your clogged drain in tub keeps coming back, stop DIY attempts and call a professional.
Why Quick Action Matters for Drain Clogs
Delaying your response to a clog can lead to overflow, water damage, or mold growth. A backed-up overflow plate may even lead to leaks behind walls. Early fixes save money and prevent long-term repair bills.
