Imagine how wonderful life would be, if every morning you could simply press a button and a warm and inviting shower would be waiting for you when you reached your bathroom.

With our digital shower Grohtherm Wireless, the dream is now a reality.

On the main control, intuitive dials for flow rate and temperature are supplemented by easy-to-read backlit digital displays. The flow rate is fully adjustable, while the temperature can be increased or decreased in increments of 0.5ÚC. And thanks to GROHE TurboStat® technology the thermostat reacts instantly to any changes in water pressure, so there’s no risk of your shower suddenly becoming ice cold or scalding hot.

The exposed Digital shower
Exposed Digital showers dispense hot and cold blended water from the pipe contained within the shower’s slider rail which is fitted on the surface of the wall.  The clever ‘exposed’ design of the shower means there’s no need for installation to cause damage to your bathroom’s décor or tiling.  Providing there’s easy access to space above the showering area (for instance, the loft), exposed Digital showers are extremely simple to install and fitting can be complete in as little as two hours.  Exposed Digital showers are the most popular choice of Digital shower and can be the easiest for the plumber to install.

The concealed Digital shower
A concealed Digital shower’s hot and cold blended water pipe is concealed in the wall.  This makes for a neat and compact shower, where only the shower’s control and showerhead are visible.  It is an especially good choice for a smaller showering enclosure where space is at a premium or if you prefer a fixed showerhead.  A concealed shower is also the best option if you cannot access the space above the showering area.  Providing the showering area is adjacent to an airing cupboard, concealed Digital showers are very simple to install. 

Body jets for concealed Quartz Digital showers should be purchased at the same time as your Quartz Digital, as they cannot be fitted afterwards.

Do I need a water pump?

1. What kind of water system you have.
This is important as booster pumps can only be added to gravity systems. You must NOT fit booster pumps to high pressure or combination boiler water systems. If you are unsure, about your water system you can ask your plumber.

2. Whether you have sufficient vertical distance from the bottom of the cistern to the top of the shower head.
This is because the greater the vertical distance (called "head of water") the better the shower’s flow rate and performance.  Typically this should be no less than one metre. Aqualisa Thermo products are specially designed to work well under gravity conditions.
However gravity systems can sometimes have a disappointing flow of water if there is not a good “head” of water.  Adding a pump can make an enormous difference to your showering experience and will allow you to add extras such as body jets.    

Handy hints 
It’s essential that you choose the right pump.  Not just for you, your family and your new shower – but for the plumbing system too.   A pump will increase the volume of water you shower can deliver per minute and it’s important to check your water tank will have enough storage capacity to cope.  Vital during the morning rush hour when everyone wants a hot shower. See our other listings for a wide range of pumps and call us for FREE advice if in doubt. 
Don’t overlook where all that extra water will go to either.  You’ll need to ensure you shower tray’s waste is sufficiently capable of quickly and effectively draining water away
