Keeping Japanese Bathtubs Clean

One of the many reasons Japanese bathtubs are popular is that the water is rarely changed. This is because the actual “getting clean” part of bathing with a Japanese bathtub takes place outside of the bathtub. The actual washing done by the bather is done in a separate area and by the time you step into the tub you are already clean. This means that the water in these bathtubs does not need to be changed as frequently as in Western bathtubs (ie after each bather).

This does not mean, however, that the water in these bathtubs should never be changed. The water in a Japanese bathtub runs at higher temperatures than the average Western-style bathtub, and over time, the water will get colder, even if you have a bathtub cover. What’s more, although bathers are often clean when they get into the tub, that doesn’t mean they are sterile. Their skin still contains dirt particles or other toxins that are released into the water. After a while, this can lead to serious buildup on the tub walls. It is also important not to forget that the water used in these bathtubs also contains its own microbes and particles and, if left unchecked, those microbes and particles can present a significant health risk.

It is important that the water drain out of the bathtubs regularly and that those Japanese bathtubs are thoroughly rinsed and cleaned before refilling.

So how do you clean Japanese bathtubs?

The first step, obviously, is to let all the water out of the bathtub. This happens differently in each tub as each tub’s drain is set up differently. Follow the instructions for your bathtub to ensure all the water is sent down the drain. Once the water has been let out, the cleaning method you use will vary depending on the type of material your tub is made of.

If you have one of the wood tubs installed, you’ll want to find cleaners that are appropriate for wood, as the cleaner you use on porcelain could damage the structural integrity of the wood. Find out what type of wood your bathtub is made of, and then ask at your local apartment building or grocery store what type of cleaner will work best on that type of wood without harming your skin.

These bathtubs that are made from Western materials like stainless steel, fiberglass, ceramic, or porcelain can take pretty much any bathtub cleaner you can find at the store. For the least impact on your skin (once the tub is refilled), use cleansers made from natural products or make your own using ingredients from your kitchen.

Whichever way you clean your Japanese bathtub, make sure your bathtub has been thoroughly rinsed before refilling it with hot water. You don’t want any chemicals getting on your skin!
