Shower Room coming on fine..

[PhilÃÂÂ]

Hello again

I have now got the marine ply type stuff for the room, now where it joins should I do something. Also it has been suggested after it is laid I varnish it with something?? What type of barrier/varnish??. I will be placing lino on it, maybe tiles?? What about that stuff that curls up the walls from the floor, any good. It is not going to be a wet room, a shower cubicle is to be installed but we have two kids!!.

The last shower leaked badly and the floor has been ripped out and joists repaired. Leaked in the three corners where the tiles meet the base (to answer a earlier question).

Now, the new shower base in a concrete one, I am supposed to bed this down with sand and cement???

Also what is the best sealant to use, the last lot was a value jobbie that moulded quite quickly.

Also guys and lasses, the new shower thingie??. It will go through a plasterboard and tiles, but what supports it to the back of the plaster board???. If it is just the pipes, it will just fall off me thinks??

Any help much appreciated.

Don't think I'd bother treating the marine ply myself, but I guess first you need to decide definitely what floor covering you'll be using.

Do you mean stone-resin? If so, 'yes' - you'll find several threads in the archives on this (used them myself last week!). But the shower tray should have come with instructions on what is required (needed to avoid invalidating warranties, too)

Silicone-rubber based... you can get sanitary grade stuff which incorporates a fungicide; don't know how effective that is at inhibiting mould but presumably can't be worse than non-fungicidal stuff

Shower thingie... that a technical term :-) Would help if you explained what type you're using: eg an electric one in a plastic enclosure? one of those steel 'bar' models? All have different solutions for fixing.

Thanks for the reply, it is a bar thingies mixer, will have two threaded pipe ends sticking through the wall??

Thought that might be it - they're b*****s to fit solidly, especially with cavity walls of some sort. Screwfix do now provide an accessory fitting pack which is well worth looking at - item ref 56419 if you can get on their site! Also do a google of "56419" on uk.d-i-y archives; you'll find discussion of this pack previously.

BTW you mention plasterboard in the shower: you'd be much better off using aquapanel board instead (search the archives for that too!) as it is much stiffer than plasterboard (so takes tiles better) and if it does get wet, won't disintegrate like pb does. Lot more expensive (comes in 900x1200 mm sheets for about a tenner IIRC?)

I have bits like that with the kit, it is the bits that connect on the otherside of the plasterboard, the side that does not get seen??. Any ideas??

[Lobster]

OK, so I take it you have something like Screwfix ref 21764, right? If so do you have something like the conical threaded covers displayed which screw down the threaded portion of the connector to bear against the wall? If so, that's a very differerent kettle of fish to what the accessory pack (56419) contains.... Screwfix don't explain it at all well, but in 56419, under the chrome cover are large metal plates with holes, which can be mounted rigidly on the wall using cavity fixing screws etc. Works quite well. I could send you a scan of the instructions if you want which is probably easiest to explain as it has pictures - email me.

I've never yet come across or heard about anything intended to fit on the hidden side of the plasterboard; which is bizarre IMHO. If you have good access to the back (eg if the other side of the cavity wall has yet to be fitted) then a large-ish (to spread the load) plate of timber wedged between the copper pipework and the plasterboard is probably your easiest and best bet.

Hi David

Thanks for your help, the shower mixer I have brought can be found at

2nd item down. It is similar to the one you have put in your last post. The main bar has two nuts on that firstly the cone shaped chrome disks screw on (trim), then a connector (dog leg I think they are called??) fits and apparently goes through the wall?? It would only just reach the other side of the plaster board. There is no way of securing, the manual says ridged pipework will hold in place??. I was going to use flexible pipe as it is hard to reach.. What you suggest sounds reasonable, so if I get the kit you recommend, I would use this instead of the trim code shaped thingy and the dog leg connector??

[Lobster]

If you *don't* use the Screwfix add-on kit, I'd recommend you use fixed copper pipework to give the whole assembly some rigidity. I originally fitted mine using plastic piping (no add-on kit) it was a nightmare!

It replaces the conical trim, yes; I think also the dog-leg bit too but memory fails me. If you order the bits from Screwfix to have a look at them you can always return them for refund without problem though, if they aren't appropriate.

Err, did you install this one ??!!

hehe, yep I did, although I think the damage was done by the previous one... Thanks why I want to get it right this time...

Hi,

For the best seal between tiles and shower tray, use a 'bond breaker' at the bottom of the seam:

Also an extra seam between the shower tray and wall would give more protection, and bedding the bottom of the lowest row of tiles in sealant is a very good idea.

cheers, Pete.
