Thermstats and pressure balance valves blend the hot and cold water supplies and control the water flow to the showerhead. Thermostatic valves are more expensive, however they offer a number of beneficial safety features in return for the additional cost.
First you will need a shower faucet (mixer valve) to mix the hot and cold water. Mixer valves are available with or without a thermostat and can be either concealed (built into the wall) or exposed.
Most head showers are used in combination with a concealed mixer. The water pipe containing the mixed water is concealed in the wall behind the tiling until it reaches the shower-head.
Hand showers can be used with either concealed or exposed mixers. You will require a shower hose and a riser bar or shower holder to attach the shower to the wall. A riser bar is the preferred choice if the hand shower is your only shower as it lets you adjust the height of the shower-head.
Choose a hand-shower that offers a choice of different spray patterns. This allows each user to personalize their experience.
Riser bars are ideal for multi-generation households as the height of the shower can be altered to suit both children and adults.
Grohe Shower Faucets
Concealed mixers or thermostats give you the freedom to locate the shower controls wherever you choose. If you are planning a large walk-in shower then locate the controls close to the entrance, so that you can turn the shower on without getting hit by an initial rush of cold water.
The controls should be easy and intuitive to use. Look out for levers and handles which move smoothly with little effort.
For maximum flexibility, choose a shower that offers a choice of spray patterns. Today’s hand showers are sophisticated pieces of engineering. They offer a selection of sensations, enabling each user to select their preferred pattern to suit their mood or the time of day.
