TECHNICAL THEME
Design trends are veering towards earthy colour palettes and natural finishes, whilst also experimenting with metallics and patterned tapware. Shown here is the Loft tall basin mixer in brushed copper from Waterware’s tapware range.
TAPWARE: Form & Function Consumers are spoilt for choice with tapware styles and options but there is more than meets the eye when it comes to the design and production process, as Waterware explains.

hen combined, three key components—the main body, cartridge and finish—deliver an appealing bathroom, kitchen or laundry tap for consumers.
The body The body will typically be manufactured using one of two base materials: stainless steel or brass. Though equally popular, each has unique characteristics. One key distinction is that brass tapware is much easier to form into different shapes and
designs and can be finished in a wide variety of surfaces and colours. Stainless steel tapware is a little harder to form, so can be a more expensive option. However, stainless steel alloy has rust resistant properties and can be used in outdoor environments, depending on the grade.
The finish Both brass and stainless steel tapware can have different colours and finishes applied to the base material, which is done using an electroplating process or PVD coating.
Looking after taps Despite the hard-working nature of a household tap, its care and maintenance can sometimes be overlooked. Consumers quite often ask for advice on the best way to keep a tap clean to ensure it maintains its looks and performance over time. Waterware recommend regular use of standard cleaning products, such as a spray and wipe together with a soft cloth. It is not advisable to use any abrasive cleaners that could tarnish the tapware and void the warranty.

Electroplating Electroplating is the process of plating one metal onto another by hydrolysis—most commonly used for decorative purposes, or to prevent corrosion of a metal. This form of additive manufacturing is referred to as an electro-deposition process. Both an anode and a cathode (the metal part to be coated) are immersed in an electrolytic bath composed of a solution of salts, including the metal to be plated. A direct current (DC) of electricity passed through the solution effects the transfer of metal ions onto the cathodic surface, plating the metal onto the item. Many materials are suitable for electroplating, including brass, nickel, gold and silver. The process gives the product additional strength and corrosion resistance, enhancing its durability.
PVD coating PVD coating, also known as thin-film coating, is a process in which a solid material is vaporised in a vacuum and deposited onto a part’s surface. These coatings are not simply metal layers, however. Compound materials are deposited atom by atom, forming a thin, bonded metal or metalceramic surface layer that greatly improves the appearance, durability, and/or function of the part or product. Both processes offer a high-quality application, so the decision as to which is best to coat a tap comes down to the
