Grohe Grohtherm 1000 Thermostatic Shower Mixer - 19984000

If you are seeking to upgrade your new shower room or ensuite, why not have a close look at this striking shower trim set from Grohe. Featuring all-metal handles and a generous 210mm diameter front fascia, it conveys a sense of quality and craftsmanship not normally associated with this price point. Clad in Grohe's scratch resistant Starlight chrome finish, it is easy to keep it looking like new with just a quick wipe over after showering. Sporting a single outlet, it can be used to supply your shower kit with a balanced and thoroughly mixed flow of water set to suit your own personal preferences.

You will also require the Grohe Rapido T thermostatic installation set that handles all water connections so we have thoughtfully included the option for this as well if you do not already have one. The ergonomic handles have a grip-friendly design so the adjustment can be made quickly and intuitively without having to look through soapy eyes. With a comprehensive 5 year guarantee, it is ideal for families who are after that extra bit of peace of mind and reassurance.
