Comparison Beurer FB 21 vs Beurer FB 50

— Water heating. The capability of the bath to warm cold water poured into it to a comfortable temperature is a valuable feature. This not only eliminates the need for users to heat water separately but also reduces the risk of damaging the device with excessively hot liquid. Typically, this function is coupled with overheating protection, which shuts off the heater when temperatures reach a critical level. It's important to mention that not all bathtubs with heating elements can actively heat the water; some heaters are designed solely for maintaining the water temperature (as explained below).

— Infrared radiation. The presence of an infrared lighting system in the design of the bath. Infrared radiation warms up the skin and joints, expanding blood vessels and increasing blood circulation in the feet; this provides not only a healing effect, but also additional comfort due to the clearly felt warmth.

— Aromatherapy. The bath includes an aromatherapy feature, denoting models equipped with oil dispensers that release fine aromatic oil particles into the air. These dispensers can operate either manually, activated by user command, or automatically, releasing portions of aromatic substances at set intervals. Aromatherapy can offer both relaxing and invigorating effects, proving effective for various conditions like colds and mood enhancement. However, it...'s crucial to be aware that the procedure itself and specific oil types may have contraindications, necessitating careful usage with appropriate precautions in mind.

— Magnetotherapy. The bath includes a magnetotherapy feature, which uses permanent magnets. This magnetic field exposure is believed to enhance blood circulation and alleviate leg heaviness.

— Maintenance of water temperature. The bath features a water temperature maintenance function, which is notably convenient as warm water tends to cool down faster than desired without additional heating. These models incorporate a heating element in their design. However, it's important to highlight that temperature maintenance doesn't always imply the capability to actively heat cold water (as explained earlier). In some instances, the heater's power may be limited, sufficient only for preventing the liquid from cooling further, and it may not have the capacity to heat cold water to the desired temperature. To ensure the device can both maintain and heat water to a comfortable temperature, it's essential to check the specifications explicitly stating both functions.

— Adjustment of water temperature. The bath offers adjustable water temperature control, typically involving both heating and temperature maintenance (as discussed previously). Models with this capability provide exceptional convenience since you can select the ideal thermostat setting once and not worry about comfort thereafter. However, it's worth noting that such baths tend to be relatively costly.

— Automatic nozzle rotation. The presence in the design of the bath of a system that automatically turns on the rotation of the nozzle when the foot is placed on it. Usually, to operate, you need to lightly press the nozzle — this is often easier and more convenient than working with a separate switch, which you would have to bend over every time.

— Shutdown timer. The presence of a shutdown timer in the design of the bath. This function allows you to set the time after which the device automatically turns off — which relieves the user of the need to keep track of time and makes it possible to enjoy a massage without unnecessary worries. In some models, the timer can have fixed values, in others almost any option is available within the operating range.

Types of working attachments supplied with the massage bath.

— Roller. The nozzle takes the shape of a compact horizontal drum with distinct raised features, resembling either "pimples" or rounded "spikes." During the massage, one should roll this drum with their foot, and these protrusions create a targeted sensation akin to acupuncture massage techniques (refer to "Types of massage"). The placement and quantity of these rollers can vary, with some models featuring a single central nozzle and others having one or two pairs of rollers at the base, providing one or two rollers for each leg.

— Ball. Ball nozzles are called round-shaped nozzles with a convex surface and balls recessed into it, playing the role of massage protrusions. Unlike a roller one, the nozzle rotates not around a horizontal, but around a vertical axis, and the balls have a large area of contact with the skin and have a softer effect on the foot.

— Pumice. Nozzle, the main working element of which is a piece of pumice stone. Due to its hardness and porous structure, pumice is well suited for removing rough skin on the feet.

— Brush. The nozzle in the form of a brush does not apply to massage, but it is often used in pedicure.

In addition to those described above, other types of nozzles may also be included in the d...elivery of modern baths: loofah pads (they act like pumice, but softer), special sponges, etc.

The maximum power consumption of the bath during regular operation is a crucial factor, primarily influencing electricity usage. However, in modern massage baths, even the most potent models typically have relatively modest power requirements. Consequently, issues related to electrical connections are usually not a concern. You should primarily consider this parameter if energy conservation or minimizing the strain on your power grid is particularly important to you. It's worth noting that this factor also partly determines the device's class: advanced models, with their rich array of features, typically demand higher power, with rare exceptions.

The presence of its own display in the design of a foot massaging bath. These displays typically feature simple monochrome screens, but they are entirely capable of showing various operational parameters: the selected mode and functions, water temperature, timer data, malfunction warnings, and more. Models with this feature are usually quite expensive, but this is due not so much to the presence of screens as to the overall abundance of functions. Adding a display to a basic model with minimal features often doesn't justify the cost.
