Does it really have two separate compartments?

Yes. The hamper is split into two sections, each with its own opening, so you can sort laundry as you go. Each side holds roughly half of the 30-gallon total.

Is water hyacinth durable for a laundry hamper?

It is sturdy when kept dry, but it is a natural fiber. Prolonged damp, wet towels or steamy bathrooms can cause it to soften, crack or fray over time.

Can it go in a bathroom?

Only a well-ventilated, dry bathroom. A damp floor or constant steam is the main risk to the woven material. A bedroom or dry utility area suits it better.

How much laundry does it hold?

The total capacity is 30 gallons across both sections, which is several loads of clothes. That makes it a good fit for couples or families rather than a single person.

Does it come with a liner or lid?

It is a woven hamper with two open compartments. Check the listing for whether a liner is included, since the natural weave can snag delicate fabrics.
