Teacher: Now, understand the problem? Solve this instance: [header] How to design a bathroom [title] Have a wet zone and a dry zone in the bathroom. [step] The wet zone is where the floor may get wet, such as by the tub or just outside the shower. The dry zone is where the floor will stay dry, such as by the door or the towel rack. <sep> (A) [substeps] Wet zones are those where faucets with bathroom handles sit partially inside the shower instead of completely outside of the shower. Sinks may also be thrown into the dry zone instead. (B) This will allow you to easily wash the floor. The dry zone is a good option because you will be able to clean up a mess even though the wet zone hasn't been cleaned. (C) Keep a good amount of space between the wet zone and the dry zone so you do not have to walk in wet spots when you use the bathroom. [substeps] For example, you may have a wet zone where the toilet is next to the shower and the sink. (D) [substeps] Wet zones use moisture glands to help lay down moisture, so the dry zone will be dry during humid periods. When your bathroom is hot, the dry zone will be drier and damper.
