Showers these days are intended to enhance the bathroom experience by providing a sense of luxury and pleasure to the user. Mixer showers are broadly classified into two types: those with a hidden valve and those with an exposed valve. The amount of space available in your bathroom is also important in determining the kind of shower that would be most suitable for your Plumbing System. Mixer showers combine hot and cold water supplies before they are released via the showerhead. Electric showers draw water from the cold water supply, where it is heated by the heating components inside the shower unit itself.
