Well, I went for 3x2 in the end, and the floor is as solid as the proverbial rocky thing. Thanks again to all those who provided advice.

Just one further question, hopefully. What size timber should I use for the noggins? The shower tray is 700mm deep, 900mm long and that depth will span two joists, but I need to incorporate a third joist for full support.

Thank you. Unfortunately that link doesn’t work either, but I get the picture. Next week I’ll be going to the plumbers merchant to buy the bits for the shower, so I’ll ask him about these wretched reducers whilst I’m there.

No, it’s perfectly round as far as I can tell. Brand new 22mm pipe won’t slide into the fitting either, and in fact the edges more or lesss match up. I bought 22/15solder ring reducers from 2 different outlets, Screwfix and an Amazon seller, but neither works. Flummoxed, in all honesty...

And another thanks from me. My floorboards are 20mm thick, so 18mm would probably be perfect for our purposes, give or take the odd mm. I've been having problems with the plumbing. I fitted 22mm/15mm reducing compression tees for the rising shower feeds, and one of the tees leaked constantly...

Fair comment, especially re the effect on height difference. The previous floorcovering was porcelain tiles on top of 5mm plywood, and following their removal there's a height difference of about 15 mm. I'll measure up once I get hold of that 18mm and consider my options. I used noggins on...

Thanks again. I'll put on my best "slightly dumb DIYer" smile, head for the builders' merchant and ask nicely if they'll change one of the 9mm boards for 18mm. Might ask if they can get some thinner floorboards for me whilst I'm there, hee hee.

Tray is already bought and it’s not steel, but thanks anyhow for your thoughts and experience.

Thanks very much. I don't intend to remove the floorboards and lay the plywood directly onto joists, but lay it on top of the floorboards because they're solid and in decent nick. It seems to me that would be the strongest base possible. I'll get some 18mm ply on Monday. Hopefully they'll take...

It’s an isolating valve, and it might be there to drain the pipework for maintenance purposes. Or maybe it’s a redundant connection to a removed appliance. In any case, that kind of leak can sometimes be cured simply by tightening the leaking nut. Take two adjustable spanners, use one to hold...

Evening all Following on from another thread where I asked about shower plumbing, I wanted to ask what constitutes a suitable plywood base for a shower tray when the ply will be sited on floorboards. I have 4 inch T and G boards on the bathroom floor, in reasonable condition and fairly level...

Thanks for that. My options are mounting up nicely, thanks to you guys.

Thanks again and yes, that's a fair point. I've already bought the copper and I'll "dry run" it to check whether its feasible to cross the pipes over as they climb my Grand Canyon. I think it will be, but if not then yes, crossing in plastic would be better than hacking more chunks out of the...

“Pulling an underpass”...I like that

Good idea, is that. The one we’ve picked is a bit more conventional, no flexis, just “left and right”.

Thank you. We've had a very competitive quote for a shower unit that ticks all our boxes. All our boxes, that is except the option to swap hot from left to right. Its too tricky and labour intensive for me as a DIYer to swap the supply pipes around ( this is only a two bedroom bungalow but...

Thanks for the reply. Not sure because I haven’t ordered it yet, but I assumed that hot on the left was standard. Pic below.

Evening all Pic shows a run of pipe emerging underfloor from Lord knows where, and terminating in feeds for a bath. The bath has been removed, those feeds are capped off, and I want to divert the pipes in the pic up the wall to feed a mixer shower. However, the hot feed is on the right (22mm...

This thread has probably come to the end of its natural life now, but just for info, I have something similar and only on the short flush. I fitted a new flush valve about 18 months ago--the type you can dismount to change washers without dismantling the cistern--and it thumps like Hell on the...
