How To Keep Bath Water Warm

May 9, 2023

Taking a warm bath is one of life's simple pleasures. However, if the bath water cools down too quickly, the relaxation can quickly turn into discomfort. In this article, we will explore different ways to keep bath water warm for longer.

1. Preheating the bathtub

One effective way to keep bath water warm is to preheat the bathtub. To do this, fill the bathtub with hot water and let it sit for a few minutes before draining it. This preheats the tub and helps to prevent heat loss when the warm water is added.

2. Insulate the bathtub

Insulating the bathtub can help to keep the water warmer for longer. This can be done by placing a layer of insulation material, such as bubble wrap or foam insulation, under the tub. This will help to prevent heat loss through the floor of the tub and keep the water warm for longer.

3. Use a bath pillow

Using a bath pillow can help to trap heat in the water, keeping it warm for longer. A bath pillow can be placed behind the neck or back, creating a seal between the body and the water. This reduces the amount of heat lost to the air and keeps the water warm.

4. Add hot water periodically

Adding hot water periodically can help to maintain the water temperature. This can be done by adding a small amount of hot water every few minutes. However, be careful not to add too much hot water at once, as this can create hot spots in the water.

5. Use a bath heater

A bath heater is an electric device that can be placed in your bathtub to keep the water warm. It works by circulating the water and keeping it at a constant temperature. This is a great option for those who take long baths or want to keep the water warm for extended periods.

6. Keep the bathroom door closed

Keeping the bathroom door closed can help to prevent heat loss. This will help to keep the air in the bathroom warmer and reduce heat loss through the walls and windows. This will in turn help to keep the water warm for longer.

7. Use a thick bath mat

Using a thick bath mat can help to insulate the bathtub and prevent heat loss through the floor. A thick, plush mat can help to keep your feet warm and reduce the amount of heat lost through the bottom of the tub.

8. Cover the bathtub

Covering the bathtub can help to trap heat and keep the water warm for longer. This can be done with a plastic cover or a towel. Simply place the cover over the tub after filling it with warm water. This will help to prevent heat loss and keep the water warm.

9. Take shorter baths

Taking shorter baths can help to reduce heat loss and keep the water warm for longer. While long, luxurious baths are enjoyable, they can also cause the water to cool down quickly. By keeping your bath time to 15-20 minutes, you can enjoy a warm bath without having to continually add hot water.

10. Use bath salts or oils

Adding bath salts or oils to your bath can help to keep the water warm for longer. Bath salts contain minerals that help to retain heat, while oils create a barrier that reduces heat loss. In addition, the salts and oils can also help to relax your muscles and soothe your skin.


Keeping bath water warm is essential for a relaxing and enjoyable bathing experience. By following these tips, you can keep the water warm for longer and enjoy a luxurious soak without having to worry about the water quickly cooling down. Whether you choose to use a bath heater, add hot water periodically, or cover the tub, there are many ways to keep your bath water warm and toasty.
