Large luxury 200mm round drencher head

Most showers are supplied with a standard sized shower head which are designed to simply get the job done. Your shower doesn’t have to be like that and won’t, with this large 200mm round drencher head. It’s ideal for getting that downpour feeling but with all the luxuries of a hot shower. Perfect!

Adjustable drencher head

Not only is the drencher head a fantastic size to give you the perfect rain-fall experience, it's also adjustable! The drencher head features a ball joint between the head and the connection, allowing you to tilt the drench head to direct the water flow exactly where you want it.

Magni-flo Technology

Mira created Magni-flo™ technology to allow you a powerful, revitalising shower even with water pressure as low as 0.1bar. The clever technology optimizes the internal valve waterways, giving you up to 3 times more water flow, automatically enhancing your shower to give you the ultimate showering experience.

Thermostatic Stable Gauge

Precise temperature control

Standard showers can have hot temperature spikes when others in the house turn on taps or flush the toilet.

Thermostatic control means that this shower will hold its temperature steady at all times. It dynamically adjusts the hot and cold water offsetting the everyday changes in water pressure experienced in most family homes.


Solid brass body

Has your shower been the same one since you moved in several years ago? It’s probably about time you gave it an update, especially as it's something you use every day. This shower valve has been constructed from a good quality solid brass, which is designed to be long-lasting and finished to a high standard.

Chrome Finish

Polished chrome finish

Polished chrome finishes are very popular in a bathroom, bringing style and important practicality. Chrome is super easy to clean and will match perfectly with other chrome fittings and accessories.

    We bought this shower after much deliberation. It looks neat and works amazingly well. The water-pressure is really lovely and the shower knob itself really neat. The temperature adjustment is accurate and easy to use even with soapy hands! I love this shower and would recommend to everyone. Plumber who fitted the shower also showed me how well the valves are made (he was very happy).

    Very pleased with product. Wasn't sure that large head would be any good with low pressure but it was better than expected. Shower is trim fit to the wall and looks good. All been working well now for approx three weeks. Company has a great service. It arrived within four days.
