How To Make Shower Water Hotter?

Taking a hot shower after a tiring day can be extremely rejuvenating. The warm water and steam blend can act like magic to relax your mind and body.

However, if your shower water isn’t getting hot enough, you’re missing out on these benefits.

Fortunately, there are several effective ways to increase your shower water temperature. Let’s dive deeper into this topic.

How To Make Shower Water Hotter (easy guide)

Checking and Adjusting the Water Heater Settings

An obvious place to begin is your water heater:

  • Inspect the current temperature setting: Most water heaters have adjustable thermostats. Typically, the recommended setting is between 120°F and 140°F.
  • Adjust the temperature: If your water heater is set at a lower temperature, adjust it to a higher setting and wait a few hours for the water to heat up. Use caution, as setting the temperature too high can cause burns.

 Installing a Thermostatic Mixing Valve

If adjusting the water heater didn’t work, consider installing a thermostatic mixing valve:

  • Purpose: This valve mixes hot and cold water to prevent anyone from being scalded if the water gets too hot.
  • Installation: The process is tricky and often requires a professional. Remember, an incorrectly installed valve can cause issues.

Check for Sediment Build-Up

A build-up of sediment in your water heater might affect its efficiency:

  • Flushing the water heater: You can flush out sediments by attaching a garden hose to the valve at the water heater’s base. Open the valve to let the water out until it runs clear. If unsure, consider professional help.

Consider Replacing Your Water Heater

If the above steps don’t work, you might need to:

  • Evaluate the condition of your water heater: Old or damaged water heaters may not function efficiently.
  • Consider a replacement: It might be time if your water heater is over 10 years old.

Consult a Professional

Lastly, if you’ve tried all these methods and still can’t achieve the desired temperature, it’s time to:

  • Call a plumber: A professional can accurately diagnose and solve intricate plumbing issues.
  • Research reputable professionals: Look for certified plumbers with good reviews.

This guide should help improve your shower temperature. Remember, safety is essential, and it’s always preferable to seek professional help whenever unsure. Enjoy a warm, rejuvenating shower!

  1. Inspect your Delta Shower Valve: Delta shower valves come with adjustable rotational limit stops that manage hot and cold water mix. The stop is usually a plastic disc that you can adjust to change the water temperature.
  2. Remove the Shower Handle: You’ll need an Allen wrench to remove the handle of your Delta shower. In some models, you might see a set screw on the side or bottom of the handle.
  3. Locate the Rotational Limit Stop: Once you’ve removed the handle, you should see the rotational limit stop. It’s a piece of plastic attached to the shower valve cartridge.
  4. Adjust the Stop: You can increase the water temperature by rotating the stop clockwise. Make small adjustments and test the water temperature each time to avoid making the water too hot.
  5. Re-attach the Handle: Reattach the handle using the Allen wrench once you’ve achieved the desired water temperature.
  6. Test the Water Temperature: Finally, turn on the shower to check the water temperature. If it’s still not hot enough, repeat the process.

Remember, it’s always recommended to consult a professional plumber if unsure about any parts of the process. And if your shower valve seems old or damaged, consider replacing it entirely.

  1. Remove the Bathtub Faucet Handle: You might need an Allen wrench or a screwdriver, depending on the model of your faucet.
  2. Locate the Temperature Limiter or Control Valve: You’ll find the temperature limiter once the handle is removed. This part helps control the mix of hot and cold water.
  3. Adjust the Temperature Limiter: To increase the water temperature, adjust this limiter. Most commonly, you’d make a counter-clockwise turn for hotter water.
  4. Replace the Faucet Handle: Once the adjustment is made, put the handle back on.
  5. Test the Water Temperature: Finally, test the water to see if it’s now at the desired temperature. If it’s not hot enough, you might need to repeat the steps with further adjustment.

You can also attempt to insulate your bathtub or preheat your tub before adding water to keep the water warm for longer.

Remember, when adjusting the water temperature, be cautious to prevent accidentally creating temperatures that could cause scalding. Always consult a professional plumber if you’re unsure or uncomfortable making these adjustments yourself.

How to make shower water hotter water heater?

To make shower water hotter from a water heater, you can follow these general steps:

How to make shower water hotter water heater
  1. Check Current Temperature: Firstly, test the water temperature from the tap closest to the water heater. Run hot water for at least three minutes, fill a glass, and check the hot temperature.
  2. Adjust Temperature on Heater: If the water temperature is less than desired, you can usually adjust it directly on the water heater. However, for safety reasons, it’s recommended that the water heater be set at around 120°F (49°C).
  3. Check for Issues: If temperature adjustment doesn’t help, potential issues could include damage to parts of your water heater, such as a broken gas valve.
  4. Consider a Heater Booster: A water heater booster is designed to increase the amount of hot water a heating system can provide. With a booster, you can raise the temperature from the factory setting of 120° to 140° and then add a mixing valve that mixes the overheated water with cold water to make the stored hot water go further.

However, all these adjustments should be performed by a qualified professional or after referring to your water heater’s user manual, as incorrectly modifying a water heating system could pose risks.

How to make shower water hotter & longer?

Here are some steps to ensure your shower water stays hot longer:

  1. Check Water Heater settings: Ensure your water heater is set to an optimal temperature. About 120°-125°F (48-52°C) is typically recommended. You can increase the temperature, but be cautious as temperatures above 125°F (52°C) can cause scalding.
  2. Upgrade Your Water Heater: If your water heater is old, it may not be able to produce and maintain hot water as effectively as newer models. Consider upgrading your water heater.
  3. Insulate your Water Heater: Adding insulation to your water heater and the hot water pipes can reduce heat loss, and your water will stay hotter for longer.
  4. Schedule Showers Appropriately: Spacing out showers can allow your water heater to recover. This is especially important if multiple people take back-to-back showers in your home.
  5. Install a Water Heater Booster: This add-on in your water heater can add up to 45% of capacity to water heaters, ensuring longer periods of hot water.
  6. Clean your Water Heater regularly: Sediment buildup in water heaters can reduce efficiency. Regularly flushing your water heater can improve its performance.
  7. Limit Use of Other Appliances: When washing clothes or dishes, consider using cold water or doing these tasks during low hot water demand periods.

Note that these adjustments should be executed by a professional or someone with proper knowledge. Always refer to the specific user manuals and safety considerations for your appliances.


Achieving hotter and long-lasting shower water involves checking and adjusting your water heater settings, thoroughly insulating your water heater and hot water pipes, and possibly even upgrading to a newer one.

Shower usage should ideally be spaced out for the water heater to recover.

Regular maintenance of your water heater is also crucial to enhance its efficiency.

While these steps on how to make shower water hotter may enhance your experience, it’s essential to proceed with guidance from the user manual or consult professionals to avoid any risk of scalding or damaging your appliances.
