3 Features Included In This Product Explained



A diverter, specifically in bath-shower combos, redirects the water flow from the bathtub spout to the showerhead. You can activate it using the nozzle in the bath shower mixer tap.

Thermostatic Control

Thermostatic Control

Thermostatic shower control works behind the scenes to achieve or maintain water temperature output from a showerhead. With the built-in safety feature, the shower provides a consistent water temperature.

Medium Water Pressure

Medium Water Pressure

Water systems operating at a pressure between 0.5 and 0.9 bar are considered medium pressure. Products usually come labelled if they are suitable for use in medium pressure.

From : London Overall Rating: Date: August 6, 2023 Nice look but bad valve design
Bought that year and really regretted it straight away after fitting. It looks good, but the control is loose, whatever my plumber tried. It also comes out some as the little lever needs to be screwed into a tiny emplacement, not even a hole, for it to move from right to left. This is a really bad design. No choice but to keep it for now. Also, water drips when switching from the main head to the hand shower, I have a video of it, my plumber tried to make it tighter but agreed that is a bad design, not even faulty. I wouldn't recommend

PeterDavidson Asked :

What is max possible output in L/min of the Tavistock quantum sqt1611? We have approx 15 L/min output from mains and a combi boiler which can provide 18 L/min but the current output from the shower is only 12L/min? Want to know how if we can get more power from this shower i.e. what’s its max output?

Answered By QS Team Answered by the QS Technical Team

We have attached the technical data sheet for the shower valve itself. The flow rate matrix goes all the way up to 4.0 Bar which would pump around 34 litres a minute. However, there are a lot of variables involved such as pipework etc that can reduce the flow. A plumber can adjust the temperature control (anti scold) valve to increase the overall flow of hot and this will also increase the flow rate per minute. It would be set at around 46 degrees centigrade – upping this slightly will bring more hot into the mix and in turn increase the flow. "

Julie Asked :

Could you please let me know if the showerhead tilts at all? Thank you

Answered By QS Team Answered by the QS Technical Team

Many thanks for your email, I have had a look into your email and the large shower head is fixed so it won’t tilt.
