A bathtub, also known simply as a bath or tub, is a container for holding water in which a person or animal may bathe. Most modern bathtubs are made of thermoformed acrylic, porcelain-enameled steel, fiberglass-reinforced polyester, or porcelain-enameled cast iron. A bathtub is usually placed in a bathroom either as a stand-alone fixture or in conjunction with a shower. Modern bathtubs have overflow and waste drains and may have taps mounted on them. They are usually built-in, but may be free-standing or sometimes sunken. Until recently, most bathtubs were roughly rectangular in shape, but with the advent of acrylic thermoformed baths, more shapes are becoming available. Bathtubs are commonly white in color, although many other colors can be found. The process for enamelling cast iron bathtubs was invented by the Scottish-born American David Dunbar Buick. Older Western bathtubs are usually made of rust-treated steel or iron. For a long time, most bathtubs are rectangular. In recent years, due to the increasing popularity of acrylic heating bathtubs, various shapes of bathtubs have begun to appear. The most common color for bathtubs is white, but there are other shades such as pink. Most bathtubs have a drain level at the bottom and a drain level in the upper part to prevent overflow. Some have the hose installed at the edge of the bathtub.

The clawfoot tub was considered a luxury item in the late 19th century, originally made from cast iron and lined with porcelain. Modern technology has contributed to a drop in the price of clawfoot tubs, which may now be made of fiberglass, acrylic or other modern materials. Clawfoot tubs usually require more water than a standard bathtub, because generally they are larger. While true antique clawfoot tubs are still considered collectible items, new reproduction clawfoot tubs are chosen by remodellers and new home builders and much like the Western-style bathtubs , clawfoot tubs can also include a variety of shower head options. Freestanding tubs have become popular in recent years as a result of larger bathrooms being constructed. Freestanding bathtubs may be made from various materials such as stone resin, cast stone, acrylic, cast iron, fiberglass, porcelain, copper, and cement. A baby bathtub is one used for bathing infants, especially those not yet old enough to sit up on their own. These can be either a small, stand-alone bath that is filled with water from another source, or a device for supporting the baby that is placed in a standard bathtub. Many are designed to allow the baby to recline while keeping its head out of the water. Hot tubs are common heated pools used for relaxation and sometimes for therapy. Hot tubs became popularized in the U.S. during the early hippie era (1967–1980), appearing in films and music.

Bathtub faucets are valves in the bathroom that control the release of liquids or gases. Water for baths, sinks and basins can be provided by separate hot and cold taps; this arrangement is common in older installations, particularly in public washrooms/lavatories and utility rooms/laundries. In kitchens and bathrooms, mixer taps are commonly used. In this case, hot and cold water from the two valves is mixed before reaching the outlet, allowing the water to emerge at any temperature between that of the hot and cold water supplies. Mixer taps were invented by Thomas Campbell of Saint John, New Brunswick, and patented in 1880. For baths and showers, mixer taps frequently incorporate some sort of pressure balancing feature so that the hot/cold mixture ratio will not be affected by transient changes in the pressure of one or other of the supplies. This helps avoid scalding or uncomfortable chilling as other water loads occur (such as the flushing of a toilet). Rather than two separate valves, mixer taps frequently use a single, more complex, valve controlled by a single handle (single handle mixer). The handle moves up and down to control the amount of water flow and from side to side to control the temperature of the water. Especially for baths and showers, the latest designs are thermostatic mixing valves that do this using a built-in thermostat, and can be mechanical or electronic. There are also taps with color LEDs to show the temperature of the water.

Vanity refers to furniture decoration used for makeup. The term dresser has been widely used by owners, customers, and home designers in modern homes, and now refers to furniture dressers.
The standard size of the dresser is about 1500mm in total height and 700mm to 1200mm in width. Such a dresser size is just right. In the preliminary preparations before home decoration, the size of the dresser should be determined. At the same time, the size of the dresser should be determined. The size should also be consistent with the style and style of the room. If the bathroom is large and airy enough, you can put your daily skin care products on the bathroom vanity, including body care products. The spacious and refreshing mirror surface, bright lighting, and the good skin condition just out of the bath will allow you to solve a complete set of maintenance in the bathroom in one go.
A toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia. In urban areas, flush toilets are usually connected to a sewer system that leads to septic tanks in Isolated areas. The waste is known as blackwater and the combined effluent including other sources is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet. The technology used for modern toilets varies. Toilets are commonly made of ceramic (porcelain), concrete, plastic, or wood. Newer toilet technologies include dual flushing, low flushing, toilet seat warming, self-cleaning, female urinals and waterless urinals. Japan is known for its toilet technology. Airplane toilets are specially designed to operate in the air. The need to maintain anal hygiene post-defecation is universally recognized and toilet paper (often held by a toilet roll holder), which may also be used to wipe the vulva after urination, is widely used (as well as bidets).

The intelligent toilet's buttock wash adopts a unique vortex rotating bubble nozzle, which has a massage effect and promotes blood circulation to avoid bacterial reproduction. The smart toilet originated in the United States and was used in medical and elderly care. It was originally equipped with a warm water washing function. After passing through South Korea, Japanese sanitary ware companies gradually introduced technology and began to manufacture, adding a variety of functions such as toilet cover heating, warm water washing, warm air drying, and sterilization. There are generally three types of smart toilets on the market, one is a smart toilet with cleaning, heating, sterilization, etc., and the other is a smart toilet that can automatically change the cover; the other is an intelligent toilet with automatic cover change and cleaning function. With the continuous development of bathroom functions, the humanized appearance and functional design make the toilet only eight buckets high, reflecting the owner's pursuit of a comfortable life and a healthy life. Nano antibacterial seat ring, paperless warm water cleaning, automatic flushing and automatic deodorization, constant temperature seat ring, multiple intelligent "insurance" barriers, etc. are all humanized designs of smart toilets.

Bath mirror is an indispensable part of bathroom space, a clear and bright bath mirror can bring people a good mood when dressing after bathing. According to different styles, it can be divided into fairy tale style bath mirror, modern style bath mirror and industrial style bath mirror. The appearance of bath mirrors is varied. Compared with ordinary mirrors, bath mirrors need "three defenses": waterproof, rust-proof, and anti-fog.
