Do you know how to keep bathtub water warm or hot? Taking a warm bath is the ultimate way to relax if you have had a tiring and stressful day at work. This becomes all the more appealing when the weather starts turning cold.
But, it can be quite frustrating when you jump into a tub full of warm water, only to realize that the water remains warm for hardly 10 to 15 minutes.
After that, you are just lying in a shallow pool of cold water. It’s quite infuriating and most people don’t bother staying in the tub; they instantly jump out due to this.
Thankfully, there are quite a few tips that you can follow to ensure that your tub retains the heat. There are several factors that you need to consider here as well. But, here are six tips to help you keep the water in your bathtub warm.
How To Keep Bathtub Water Warm Or Hot
- Bathtub That Keeps Water Warm
The first thing you need to understand is that the material used in your tub is going to have a major impact on its level of insulation. For instance, there are several materials that offer much better insulation as compared to others.
This simply means that they are able to retain heat for a much greater period of time. For instance, acrylic bathtubs are quite popular because of their ability to keep heat stored.
They are available in a multitude of different colors and styles, and you can even choose a suitable size based on your needs. Apart from that, you also get all of the benefits that acrylic has to offer.
For instance, these tubs are relatively lightweight, so even when they are full with water, they do not put a major strain on the floors.
If you notice that the water becomes cold very quickly, you may want to consider switching to an acrylic bathtub. Not only are they going to increase the value of your property by a significant margin, but they will make your life easy as well.
Acrylic tubs are quite durable and long lasting as well, so think of it as a viable investment that is going to offer dividends in the future.
- Increase the Temperature When Preheating
When you are preheating your bathtub, it might be a wise idea to preheat it to a much higher temperature than what you are going for.
For instance, if the water is hotter, it will cool down over a longer period of time. It’s quite similar to the way people preheat their pans when they want to sear their steaks.
The material used in your tub is just able to absorb more of the heat and that’s going to ensure that the water remains hotter for a longer period of time.
Remember, the water will cool down much faster in the winter months, so that’s something you have to consider as well.
- Always Choose a Decent Bubble Bath
Bubble baths are not just about having fun in the water. You should know that these bubble baths actually play a very important role in keeping the water warm.
Once you preheat the tub and the material absorbs the heat, you should know that heat is also being dissipated from the top. The surface of the water is constantly losing heat. To combat this problem, you may want to use a bubble bath.
The bubble bath is simply going to create a layer that protects the heat from escaping. If the number of bubbles on the surface is higher, it’s going to be much easier for the water to retain all of that heat.
- Close the Bathroom Door
This is a given in most situations, but there are a few people who like to take a bath with their bathroom door open. For instance, if you live alone, you wouldn’t really care if the door is open or closed.
On the other hand, if you have kids, you may want to keep the door opened so that you can always keep an eye out for your kids.
However, when the door is open, it simply allows the hot air to escape easily into the atmosphere and in the house. By closing the door, you are going to ensure that the heat remains trapped inside.
Using the same logic, if there is a vent or a window in your bathroom, you may want to keep it closed as well. Make sure that the windows remain shut so that you are able to retain most of the heat inside the closed spare.
- Buy a Few Hot Stones
Hot stones are not just for dissipating heat; they will also improve the aesthetic appeal of your house. They are usually made from basalt and are able to retain heat for much longer time periods.
You can put them in your bath after preheating them. They are going to increase the temperature as the heat continues to transfer from the stones into the water.
Ultimately, this is going to increase the temperature of the water and keep it hotter for a greater period of time. Make sure you buy good quality hot stones, because there are several less expensive materials available in the market that might not do the trick.
- Invest in a Heater
If you are really serious about your baths and are willing to go all out, why not buy a space heater? If your bathroom remains cold throughout the day and night, especially in the winter months, investing in a space heater is a great idea.
You may want to hire an expert to take a look at the insulation around your bathroom as well. If it’s not properly insulated, you may want to consider getting a layer of insulation added around the bathroom.
Simultaneously, you can purchase a small heater and keep it in the bathroom. Just activate it and it’s going to heat up the room. Remove it once you are done heating up the bathroom before you jump into the tub!
Now that you know how to keep bathtub water warm or hot, you won’t have to worry about your bath water cooling off quickly when the chilly winter season hits!
