Do I need an exposed or concealed shower?

Exposed Thermo showers can be fitted directly on to the wall.  This makes the product easier to install as there will be little disruption to the bathroom wall.  To make installation even easier, consider utilising exposed pipework, which requires no wall excavation at all.  However, it’s worth remembering that exposed Thermo shower controls are normally larger and could encroach upon a small showering area.
Concealed Thermo showers have their valves fitted into the wall.  This means that the wall must be excavated to accommodate the shower’s valve.  The controls will be neater and more compact and are a good choice for a smaller showering enclosure where every inch of space matters.
