Do RVs have bathrooms?

Whether or not RVs have bathrooms, and the type of bathroom, depends on the RV. Most larger RVs have a “dry bath”. “Dry” means that there is a stand-alone shower. Some showers in dry baths are very small, and some are the size of residential showers. Many smaller RVs have “wet baths”, meaning there is no separate shower. There is a shower nozzle in the bathroom space, and when taking a shower everything in the space gets wet (including the toilet, shelves, walls, etc). Wet baths are usually carefully designed so that everything in the bathroom can get wet without damage. Some RVs do not have bathrooms, but have toilets that are hidden in a cabinet and slide out. This is more common in DIY conversions.
