The word "toilet" initially meant "wash-room", without reference to sanitary facilities. Early indoor toilets were known as garderobes because they were used to store clothes, as the smell of ammonia was found to deter fleas and moths. However an Outhouse was usual until the nineteenth century, and only a few wealthy houses and luxury hotels had indoor toilets connected to drains and sewers. Lidded "chamber pots", kept in specially designed bedside cabinets and used in bedrooms by ladies and invalids, and portable bathtubs, could be emptied and washed in an outhouse.
