How to Stop Toilet Backsplash

Preventing toilet water from splashing out of the bowl when flushing is an annoying yet common problem. Here are some tips on how to stop toilet backsplash.

Adjust the Water Level in the Toilet Tank

The most effective way to stop toilet backsplash is to adjust the water level in the tank.

  • The water level should be at least 1 inch below the overflow tube. This prevents too much water from entering the bowl.
  • If the water level is too high, simply flush the toilet and then adjust the float higher.
  • For ballcock style mechanisms, bend the float rod down slightly. For Fluidmaster style, twist the adjustment clip.
  • Be sure to flush a few times to check that the adjusted water level prevents backsplash.

Use a Toilet Backsplash Guard

Another easy option is to install a backsplash guard that fits inside the toilet bowl. These guards stop the upward splash trajectory.

  • Look for a guard designed specifically to prevent backsplash and splashing.
  • Models that rest on the overflow tube work best.
  • Guards slip over the tube and stay in place by friction. No tools or installation needed.

Install an Elongated Toilet Seat

Switching to an elongated toilet seat can help reduce backsplash.

  • The extra length positions the back of the seat further from the back rim of the bowl.
  • This allows waste to drop more directly down without hitting the rim at an angle.
  • Just be sure to get one sized appropriately for your toilet bowl shape and dimensions.

Use Toilet Paper to Soften the Landing

For a quick fix, place a small amount of toilet paper in the bowl before using it.

  • 2 to 3 squares is enough to help break the surface tension of the water.
  • As waste hits the paper, it will reduce splashing straight up.
  • Flushing the paper down each time keeps the bowl clear for the next use.

Clean Any Mineral Buildup

Hard water mineral deposits on the back of the toilet rim can worsen splashing.

  • Use a pumice stone or toilet cleaning brush to scrub away any scale or crusty buildup.
  • Vinegar or lime scale removing cleaners also help dissolve deposits.
  • A clean, deposit-free surface helps waste drop straight down into the water.

Consider Replacing Old Low-Flush Toilets

If you have an outdated toilet, a full replacement may be needed to completely stop backsplash.

  • Some pre-1994 toilets are inefficient and prone to splashing due to low water volume per flush.
  • New high-efficiency toilets have a redesigned bowl shape and siphon jet for a cleaner, splash-free flush.

With a few simple adjustments or accessories, it is possible to prevent annoying and messy toilet backsplash. Carefully adjusting the tank water level is often the most effective solution. For a quick fix, try using toilet paper or a backsplash guard.

Frequently Asked Questions About Stopping Toilet Backsplash

What causes toilet water to splash out of the bowl?

Toilet backsplash is mainly caused by the force and angle of the water entering the bowl from the tank. If the water level is too high or waste hits the back rim of the bowl at a sharp angle, backsplash occurs.

Does toilet shape affect backsplash?

Yes, toilet bowl shape can impact backsplash. Elongated and open-front bowls tend to have less backsplash than round bowls. Newer low-profile toilets are often designed to prevent splashing.

Why does my new low-flush toilet splash so much?

Some older 1.6 gallon per flush toilets have less water volume which can increase backsplash. Installing a flapper to match the flush volume or adjusting the tank water level lower can help.

Is it OK to put things in the tank to reduce the water level?

No, do not place bricks or bottles in your tank. Improperly altering the tank can damage the flushing system. Use the float or Fluidmaster adjustment to lower water level appropriately.

What should I do if the toilet backsplash guard doesn’t fit?

Look for a universal or adjustable guard designed to fit most toilets. You can also trim plastic guards with scissors to create a better fit. Check that it rests securely on the overflow tube.

Why does backsplash seem worse at night?

Toilet splashing noises are more noticeable at night when it’s quiet. The backsplash is likely the same during the day. Try softening the landing with toilet paper or installing a backsplash guard.

In Conclusion

Preventing messy and annoying toilet backsplash is possible with a few simple fixes. Start by double checking that the tank water level is not too high. A toilet splash guard slipped into the bowl can also deflect the upward water trajectory. For a quick fix, lay toilet paper across the bowl surface. With the right adjustments and accessories, it is possible to keep that toilet water where it belongs – inside the bowl.
