 Roger Bisby takes Flight with Mira.
I have fitted other Flight trays but Mira’s new low profile quadrant Flight tray was straight off the production line as a new addition to the range. The tray is now stronger, whilst still being very lightweight. The introduction of a Vortex trap into a 1 ½ in. waste pipe means it will clear water faster. I coupled it up with a Mira Form shower supplied from an Alpha 35k boiler, with a flow smart thermal store. The hot water delivery of this unit is 18 litres per minute, which is a lot for a small low profile tray. If the worst came to the worst I could fit the flow restrictor on the outlet to reduce the output to 10 litres per minute.
As with most plumbing jobs you have to be a little bit adaptable to take account of things not quite looking the same in real life as they are on paper. I had the chase in the wall cut long before the tray and valve arrived, but one look at the available space in this 800mm quadrant told me that the valve would have to be moved over towards the corner to provide the maximum amount of space for the user. Fortunately, it was no real problem to put a couple of elbows on the pipes.
The valve can be mounted on a stud or masonry wall and there is a fair amount of tolerance in the depth. The cardboard building in shroud when laid out flat provides a template for cutting out the wall recess. By the time I had chopped 65mm depth out of the 100mm of brickwork there was nothing much left of the wall, and the brick gave way into the cavity, so I placed a bit of 65 mm deep Celotex in the wall and foamed it in. The screw fixings for the valve are on the face of the wall behind the plaster line so it still had a secure fixing.
The shower valve was easy to fit, as was the tray, but the shower screen has a lot of stages to the fitting, and the instructions could do with a bit of improvement. Like all these jobs if I did another one I would be a lot quicker. There is also very little room to get through the door on an 800mm tray. I can’t quite see why the door can’t be a bit wider. This is a space saving tray but if the customer is on the large side (or pregnant) they will struggle in this size of tray. If they can try one out in a showroom then all the better.
 A change of mind over the positioning meant re-routing the pipes slightly.
 The building-in shroud is cardboard and is first used as cut out template.
 The large chrome cover plate makes tile cutting a lot less critical with no holes to drill.
 The Vortex waste is designed to move water faster by siphoning it through.
 I levelled the tray on a weak mix of sand and cement but you can use silicone if your floor is level and even.
 Because the tray doesn’t have upstands I stuck some Classi Seal strip around the edge to form a flexible upstand. This was then let into the wall and tiled over.
 The Vortex trap has just 2 screws to secure it rather than a threaded waste.
 The wall panel goes in first. It has to be supported in the wall profile but not locked in.
 Fortunately it is possible to lift the sliding door onto the rollers on your own. Just as well because there is no room for a friend in this 800mm shower.
