6 Tips for How to Keep Bath Water Warm

Published on Wednesday July 17, 2024

Nothing beats a relaxing, warm bath to melt away the stress of a long day, especially during the colder months. But there’s nothing more frustrating than when your bath water cools down too quickly, robbing you of that peaceful moment.

Here are a few simple tricks for how to keep bath water hot longer.

6 Tips for How to Keep Bath Water Warm

There’s no need to keep refilling your bath with hot water when you can try these tips first!

1. Consider the Tub Material

Keeping bath water warm starts with your bathtub’s construction. Certain materials are better insulators than others, so they’ll naturally retain heat for longer.

Properly insulated acrylic tubs retain heat very well. They’re available in a variety of sizes, styles, and colors, are lightweight and durable, and resist cracking and chipping. If you love baths, it may be time to think about a bathtub replacement. A tub upgrade not only improves the bathing experience but also increases your home value.

2. “Preheat” Your Bath

Just as you would preheat your skillet before cooking or your oven before baking, you can “preheat” your bath water. Before you step into the tub, fill it with water that’s hotter than you would like. This warms the inside of your tub so it cools off slower during your bath.

3. Use a Quality Bubble Bath

Bubble baths aren’t just a fun way to get your kids into the tub. They’re actually functional when it comes to keeping bath water warm. While preheating your tub helps the tub material retain heat for longer, bubbles create a barrier along the water’s surface, preventing heat transfer from your hot bath to the cooler air outside the tub. The more bubbles in your bath, the longer the water will retain its heat. It’s fun and functional!

4. Keep the Bathroom Door Closed

Even if you’re home alone, try closing the door to your bathroom. A closed door traps steam and warms the air around the tub. It helps prevent that heat transfer we mentioned, so the water stays warmer longer.

5. Use Hot Stones

Hot stones can increase the luxury experience of your bath while keeping the water warm. Specially designed bath stones (or massage stones) tend to be made of basalt, a volcanic stone known to retain heat at very high temperatures. By preheating these stones and adding them to your bath, they’ll slowly release heat into the water as you bathe. They’re also great for easing tension out of sore or tense muscles!

6. Get a Space Heater

If your bathroom is poorly insulated, your bathtub and the air surrounding it are likely responsible for stealing the heat from your bath water. (See above, re: heat transfer.) A small space heater can help with that.

However, keep electrical appliances away from water. You should only consider running a space heater to heat the bathroom before filling the tub, and even then, keep the space heater far from any water sources – perhaps near the door.

Once the room is heated to your comfort, unplug the space heater and move it out of the bathroom before turning on the tap. Heating the room before you bathe will help your bath water retain heat.

Ready for a Bathtub Upgrade?

If you’ve tried everything and still can’t enjoy a long, hot bath, consider upgrading to a new tub from Long Baths™. Made of high-density ABS—the same material used to make bowling balls—and coated in acrylic, our bathtubs are long-lasting and built to retain heat for a better bathing experience.
