The modern style of the SEIKO Centre Hole brightens the atmosphere of the bathroom or kitchen section. This faucet is simple to install and ideal for newly renovated bathrooms where tile breakage is not an option. Most of them have a single lever that controls the flow and temperature however, there are several twin lever taps that have one lever for hot and one for cold water, giving you greater temperature control. These basin mixers are available in a wide variety of sizes.
