Volume
The working volume of the bath is usually indicated by the amount of water that can be poured to the level of overflow.
In general, the larger the volume - the, as a rule, the more comfortable the bath, the higher the likelihood that it will be able to lie down or even dive into the water almost entirely, up to the neck. However, it should be borne in mind that models of the same volume can differ markedly in size and shape (both external and internal). This means that large capacity does not yet guarantee convenience for a particular user. In addition, filling the volume bath will take more time and require more water, which can be critical if there are meters or limited water supply (for example, hot water from the storage boiler).
Wall thickness
Wall thickness indicates not only the thermal conductive properties, but also the durability of the product. However, the same parameter affects the price of the device. Accordingly
thick-walled baths makes no sense to acquire for rare use. It is enough to make do with
5 mm .
Central drain / overflow
Models of baths in which the location of the connection of communications (drain, overflow) is in the central part, i.e. at the long side, not at the short side.
Tubs with central drain will be appropriate in cases of complications of access to communications from the end sides and can be said to be more elegant and aesthetic when fully connected.
Dimensions (LxWxH)
Size of the bath in length, width and height. When choosing, it should be borne in mind that the length and width are specified on the outer dimensions - this allows you to estimate the place required for the installation of the bath, but its internal dimensions are inevitably obtained less. But as a height it is customary to indicate the depth - the distance from the top edge to the bottom. Here we note that the high altitude allows you to dive deeper into the water, but may cause some people (for example, elderly or suffering from leg diseases) problems when entering the bath.
