Shower tray fitting advice sought

[Goldspoon]

I am awaiting delivery of a shower tray over the next few days and have started thinking of best way to fit the tray. It is not square by the way but all curves (except two sides that butt to wall).

Will be tiling wall above tray after fitting. Tray is about 2" deep (so no tall sides).

I did think of tray on floor and trap/pipes running under floor. Problem is that wooden joists run wrong way so hard to do and trap will not be accessible for maintenance.

So think will raise on a wooden frame with 3/4" ply board. As a reminder this is a large curved edge tray (expensive shower as tray and glass etc. was £2,700).

Question is... should I make the wooden frame of a size where the tray "drop edge" just hangs over the edge of the wooden frame? If so I then have to fill the gap between the bottom of the tray and the floor (in this case carpetted) and what are the different ways to fill this gap? I intended to make the wooden base high enough to allow access to the trap if required (say 6" ish).

Another way I thought of is to make the wooden base bigger than the tray so the shower fits on a false floor in effect... but its all curves and then I'd have to waterproof (tile) this false bit of floor and... hmmm...

Any thoughts from those who have done this?

Thanks in advance

Hi there,

You could make the frame almost flush with the front edge of the tray and then get hold of a piece of white pvc (a bit like upvc facia board) and attached that to your wooden frame.

Hope this helps

If the floor is carpeted (.....not to my taste, but, anyway....) you could consider finishing the gap under the plinth with some laminations of thin ply glued together following the contours of the tray, then stick carpet to the ply.
Secure the ply with mirror screws or brass screws and cups so it's removable to access the trap.

I would avoid using MDF, in case it does get damp.

Thanks you two - will think about the suggestions - although carpet on a vertical surface makes me shudder (is not my choice to go with carpet at all).

goldspoon you can fit tray directly to floor if you get a mcalpine trap
or similar provided the trap does not fall in line with joists top acess for maintanance
you can drill 38mm holes trough joists fit waste & trap correctly aligned height etc clear mastic between trap washer & underside of tray always works ok for me hope this helps

Place the tray on 3/4" marine ply and make a template. Cut the ply with a jigsaw and place this on some 4" x "2 batons. Seal face of ply with clear varnish then you can finish with plastic trim.

Thanks again...

Larryleak: have just opened tray and included trap looks like an Alpine type. May be able to go straight to floor.

Gigz... sounds good. Where can one buy the plastic trim? Presumably this trim is only attached to the 3/4 ply at the top?

Some makers sell an additional riser and trim kit (approx £60) with this you get legs and trim, much better finish. What make and model is it ?

drill 38mm holes trough joists fit waste & trap

How you going to get 40mm pipe through 38mm hole

 

[larrytheleak]

gremlin 16 did i mention 40 mm pipe you could have adressed the problem rather than sideswipe at me

 

[crockett]

Larry you did mention 38mm, also you will need to know regs with regard to the size and position of the holes that you drill through the joists. I personally would never drill waste sized holes through joists. Gotta be careful when you give info out on this site, coz there will ALWAYS be someone whowill jump on you if you give out the wrong advise

 

[seco services]

nothing wrong and within regs to drill waste through right sized joist .
just people don't know the regs.

 

[crockett]

You know as well as I do that a 40mm, and yes it should be 40mm, hole drilled through 8inch joists is sailing close to the wind. And, as you also know, you cant just drill it at any height, or at any point along a joists width.

 

[seco services]

its not close 50 min in a 8"
40mm in a 6"
0.25 of the depth of a joist.
0.25 - 0.40 x the span of joist
