When choosing a rental property, it is important to check not only the layout and rent but also thetype of bathroom and its features. Because this is a facility you use every day, it is worth reviewing carefully before you move in.

What types of bathrooms are found in rental properties?

Bathrooms in rental properties are generally divided into four main types.

3-piece unit bath

This is a type in which the bathtub, toilet, and sink are combined in one space. It is commonly found in one-room and other single-occupant properties. It is easy to clean, but the lack of a dressing area and limited storage space can be drawbacks.

2-piece unit bath

This is a type in which the bathtub and sink are in the same space, while the toilet is separate. Even if a listing says "separate bath and toilet," it may still be a 2-piece unit bath, so it is important to confirm this during a viewing.

1-piece unit bath (independent bathroom)

This is a type in which the bathtub, sink, and toilet are all separate from one another, and it is often used in family-oriented properties. It is convenient to use and remains highly popular.

Shower room

This type does not have a bathtub and includes only a shower. It is easy to clean and suits single-person households well. For people who prefer showers, it can actually be the more practical option.

What should you know when choosing a bathroom in a rental property?

Check the size of the unit bath

Common sizes for single-occupant properties are1216 (120×160 cm) and 1317 (130×170 cm). For family properties, 1418 or larger is generally more comfortable. Even when the listed size is the same, actual usability can differ significantly.

Check features such as reheating and a bathroom dryer

If the property has a reheating function, family members can bathe at different times more easily, and utility costs may also be reduced. A bathroom dryer is useful for drying laundry on rainy days and can also help heat the bathroom in winter.

Understand the problems that commonly occur in bathrooms

Common issues include mold, clogged drains, and worn shower heads. Before moving in, check the condition of the equipment and ask the management company to arrange repairs for anything that concerns you.

Frequently Asked Questions (FAQ)

Q. What is the difference between "separate bath and toilet" and an independent bathroom?

A. "Separate bath and toilet" means the toilet and bathroom are separate, but the sink may still be shared within the bathroom in a 2-piece unit bath. An "independent bathroom (1-piece unit bath)" is a type in which the bathtub, sink, and toilet are all in separate spaces.

Q. Can I replace the shower head in a rental property?

A. In general, this is often allowed as long as it can be returned to its original condition. Because restoration is required when you move out, be sure to keep the original shower head. It is also wise to confirm this with the management company in advance.

Q. What are effective ways to prevent mold in the bathroom?

A. After bathing, rinse away soap residue with hot water and then lower the temperature with cold water to help suppress the growth of mold and bacteria. Keeping the ventilation fan running is also important.

Q. Should I avoid properties with a 3-piece unit bath?

A. If you live alone and mainly use the shower, a 3-piece unit bath can still be a reasonable option that keeps costs down. On the other hand, it is not ideal for people who want to soak in a bathtub every day or who often invite guests over.
