Don't Let Small Shower & Tub Problems Become Big Ones
A dripping showerhead, a slow drain, or cracked caulk around your tub might seem like minor annoyances — but over time, they can lead to water damage, mold, and expensive structural repairs. The good news is that most shower and tub problems are straightforward DIY fixes with the right parts and a little know-how.
1. Replacing a Showerhead
A clogged or outdated showerhead is one of the easiest fixes in the bathroom.
- Wrap the shower arm threads with plumber's tape (2–3 wraps clockwise)
- Hand-tighten the new showerhead onto the arm
- Give it a quarter-turn with pliers — don't overtighten
- Turn on the water and check for leaks at the connection
Pro tip: Soak a clogged showerhead in white vinegar overnight before replacing — it may just need a cleaning.
2. Fixing a Dripping Tub Spout or Diverter
If water drips from your tub spout when the shower is on, the diverter valve is likely worn out.
- Turn off the water supply to the tub
- Remove the spout (either unscrew it or remove the set screw underneath)
- Replace the diverter cartridge or the entire spout assembly
- Reattach and test — the diverter should fully redirect water to the showerhead
3. Unclogging a Slow Shower Drain
Hair and soap buildup are the most common causes of slow drains.
- Remove the drain cover and use a drain snake or hair removal tool to pull out the clog
- Flush with hot water
- For stubborn clogs, use a baking soda + vinegar treatment followed by boiling water
- Install a drain strainer to prevent future buildup
4. Re-Caulking the Tub & Shower Surround
Cracked or moldy caulk is a major source of water intrusion behind walls. Re-caulking takes about an hour and makes a huge difference.
- Remove all old caulk with a caulk remover tool or utility knife
- Clean the surface with rubbing alcohol and let it dry completely
- Apply a continuous bead of 100% silicone caulk along all joints
- Smooth with a wet finger or caulk finishing tool
- Allow to cure for 24–48 hours before using the shower or tub
5. Fixing a Leaky Shower Valve
If your shower drips even when turned off, the shower valve cartridge is likely worn.
- Turn off the water supply (at the wall shutoff or main)
- Remove the handle and trim plate to access the cartridge
- Pull out the old cartridge and replace with an identical model (note the brand and model number)
- Reassemble and test
6. Repairing Bathtub Chips & Scratches
Small chips in porcelain or acrylic tubs can be repaired with a bathtub touch-up kit — no need to replace the whole tub.
- Clean and dry the damaged area thoroughly
- Mix the epoxy filler according to kit instructions
- Apply with the included applicator and smooth flush with the surface
- Let cure fully before use (usually 24 hours)
