Some shower trays are on legs, some aren’t.
So, what’s the best/easiest way to put them in?
Do you set the ones without legs on some kind of plinth/stand?
The ones with legs do you support around edge and/or underneath?
I’ve heard some people sand cement them in. If so, how to you connect the waste if the floors down?
Cheers all

Cheers all The easiest way is to use a tray with legs, it gives loads of room to do the waste and is easy to level using the adjustable feet. this way is more likely to leak though due to the try being able to wobble on its legs and break the silicone seal. It is also a dated look having the shower raised up. It also poses a slip hazard when stepping down out of the shower with wet feet, esp for the elderly or immobile. If I have to fit a raised tray I build a plinth from 4x2 and 22mm ply so I can be sure it has a solid base. When fitting a tray direct to the floor the waste pipes and trap are assembled before placing the tray and once the tray is in place the screwdown collar will pull the trap up against the bottom of the tray. Sometimes you can create access to the trap by removing floorboards outside the area of the tray but often the only way to access it in the future is cutting a hole in the ceiling below. Not ideal and should be explained to the customer before installation and only use quality traps to avoid future issues. . |

and the other snag from a tray on the floor is,,,the trap might, and usually does, hit a joist, so you have to cut a joist more than is allowed, BB would do this and not worry, but it weakens the floor,

Sometimes you get lucky though and can go straight out the wall. I`ve seen some scandalous stuff where joists have been chopped up. The place I have just plastered has the shower wastepipe drilled through all but one of the floor joists over the kitchen to get outside (and the "fall" is up and down like a rollercoaster.) Another job was a timber framed extention where the combi boiler pipes had been drilled side by side through the whole 8ft 8x2 stud wall. It looked like a piece of perforated paper when they where done. Its a pet peeve of mine, pisses me off. Had to do a job bolting up steel plates to re-enforce joists that an over zealous plumber had drilled in the wrong places even though they had been told (and should know) not to. It was a brand new strengthened floor and the structural engineer went bonkers when he found out. |

I find the fit to the floor trays tend to be large as customers quiet often replace a bath for a wow shower, I find these prove difficult to position on your own and need your preparation work to be spot on.
I'm like Ian much prefer to make my own base as the supplied base are nearly all substandard - stiffening the existing floor is of paramount importance if you don't want a call back for "it groans as you get in and out of the shower"!

Direct on the floor every time, legs are shit! Building up a base is OK, but structurally they all move. Straight on the floor is always your best bet. Elevated tray look shit & not very handy for the kids & elderly.
On new builds we have 400mm centre joist & all sizes of trays, but we’re never stuck. We’re real Plumber & can easily alter/extend waste pipes to suit. Best thing to do is planning; Fail to plan, plan to fail!! How difficult is it to measure a job up & buy a tray that’ll fit your requirement.
Another thing to always fit is riser trays, that 20-25mm upstanding keeps water in the tray under tiles or a screen👍👍👍
