Shouldnt the shower tray not have gone in before the concrete floor, or is this a refurb?

refurb bud, taking the bath out of it..

the usual situation is to get a carpenter to make up a frame to sit under it, or do it youself if your good at this sort of this, the frame can raise it up to any height you like really but no matter what it has to be 100% level and solid no movement with the tray sitting on it whatsoever, i usually sit the tray up on the frame in position and start walking heavily all around it and looking for any movement.
If theres movment you will more than likely have hassle with tiles and shower doors etc.

The frame is set up in such a way so it extends as much as possible to the edges of the tray with allowance for you finish be it tile or plastic cover,

The frame is also set up to allow access to the shower waste , obviously if you want good access the waste should be on a outside corner.

Its tricky but can be done perfectly right with patience.
Fix the frame into positon and it cant do any harm to put a few small dabs of silicone down where the tray will sit on the frame, make sure you get a tray with upstands.

thanks bud, had someone mention put it on blocks but doesnt sound as if it would be quite sturdy.. would you put a 3/4 ply on top of the 4X2 (or similar) frame and just cut out for the trap? Also would you apply sand and cement before placing tray down..

I had to do it with blocks before as thats what the client wanted but i prefer the timber frame ,

yes theres nothing wrong with putting some Marine ply on top, not sure what size timber you want its all down to how much access vs how it looks i will leave that decison up to you but as i said it must be perfectly level no matter what and the tray must not have any movement while sitting on it.

And as i said upstands are essential on the tray.

Why are the upstands vital?? But would making the frame for a quadrant shower be tricky? (without a chippy)

Making the frame no,
getting it perfectly level with no movement whatsoever yes if floor isnt dead on.

Its up to you why do you need access to the waste?, 99% of jobs you wont have access to the waste again anyway is there something special why you need access ? or are you doing it DIY and worrying about it?

Also buying a tray with upstands is important in my opinion because it eliminates the possibility of a leak on the edge of the tray which is one of the top causes of leaks http://www.bathdisc.co.uk/popup_image.php?pID=5417

tray is already bought so dont know if it has upstands... see was also planning on running hot and cold along the bottom of the skirting to feed the sink.. Will have to chase hole for the waste and to sit shower trap and will also have to chase for the supplies to sink & toilet because the supplies are coming from right behind where the shower is going.. Was just wondering was it worth making the trenches or would it be handier raising the shower and bringing the supplies from under it.

Trenches all the way other wise it will look ****e honestly i have seen it all before and DIY pipes along the walls are never pretty just do the trenches its worth it.

thanks bud... Only reason I even considered this way is because there is we say a kicker board all around the bathroom so all pipe work would be boxed in this area.

Well if there is already boxing and you intend to keep it use it, when i do bathrooms up if at all possible i aim to conceal all pipework without the use of boxing , as honestly the boxing always looks wrong no matter how well its done imo.

agreed its always a nicer feature.. The only advantage is it makes it easier for next plumber (ease of access)

When I put my 900by 1400 shower tray in over a concrete floor I built a timber frame out of 3by2 and then screwed a sheet of marine ply over the top. Made it nice and strong. I cut a hole out the ply for the shower waste trap to fit through.

The manufacturers said to bed the tray on an even bed of sand and cement. Porcelain tray and the weight of it found it's perfect level. My god it was heavy on my own!!

From the gap underneath I connected the wastepipe. I used solvent weld wastepipe so no leaks. I then sealed the tray to the wall with clear silicone and then tiled and then sealed again.

On the front I have skirting board permanently fixed, but have never had to remove it.

The shower trap blocked once but all I did was pull the grating out and twist the cross handle and pulled up the circular part to clear the hair.

Just make sure to fit a shower waste trap.
