I have a shower, which has long been a source of grief.
Recently I noticed that there is a very slight wobble to the base.
On pulling out the decorative plastic sides, I found that it has four feet with steel nuts on them. These are screwed into the wooden floor with a pair of wood screws per foot.
Tightening the nuts up a bit seems to make it somewhat better, but it all looks really flimsy.
Are these things just fundamentally always going to wobble, or is it just badly installed?
Is there anything I can do to improve it, or should I just rip it all out and install something with a concrete base?
Did I mention that I hate (re)doing silicone sealant?
Decorative plastic sides, on a showertray? Sounds like you need to start again, sorry.
Cheap DIY store shite I'm afraid. Solid resin based tray is what you need.
The tray is a lot like this one:
Stone resin (?).
My bad then. But the only resin trays that I have fitted have rested on a bed of cement. I did once fit a fibreglass tray with adjustable feet. Never again.
You would be better off ditching the feet and standing the base on a wooden frame , it would be much more stable
yeah, wooden base if it has to raised of the floor for the waste. cover the base in ply then bed on mortar, the bottoms of trays are never flat.
Our house built 14 years ago has a raised plastic shower base. God awful thing that cracked a few years ago. Took a panel off and could see that it is essentially fibreglass with what looks to be some wood or similar making the bottom section.
The crack had appeared in the outer resin that held the base to the edge which made it creak badly but not crack on the finished surface inside the shower. To get it out and replace it we had to destroy the shower cubicle and the tiled walls - which took half the plasterboard with them.
Basically ripped the whole lot out and started again. Because of the stupid layout of the drain I couldn't use a different base, so went with the same again.
12 months later, a loud crack and it went in the same place.
Ended up using 4 of the below under the actual floor bit of the shower (not the edges where the factory supports are). Made it very rigid and have not has a problem since.

They are quite wide so spread the load nicely.
The rough arse in me would do this:
Spray some expanding foam under. Just enough.
As for flex: you can get seals that flex:

I went through two trays in 5 years, tray kept moving. Grout cracking In the end I ripped out the floor joists and floorboards and re did it all. That worked.
Just realised I misread your reply.
Stone resin shower trays are designed to take weight and not flex. Very heavy though and can take some positioning. For me it's needed two of us to get upstairs and in place.
Those feet look like they might do the trick.
I'll try those, and if I resurrect this thread in 6 months time, it will be for advice on ripping out the floor joists and floorboards and redoing it all.
This is all from a shower put in by a local company which was to fixup a previous one that ended up leaking and involved an insurance company. And the fixup had to be fixed up after a year.
Gaaahhhfffhhh1!
