Has Anyone Known This To Happen

[emmie]

the shower base is now somewhat bubbled, i have anti slip bubble type mats down,
they appear to have made imprints in the base, and now its bobbled, truly strange.

not sure if anything can be done, i just wondered if this is something that happens, i think the
base is enamel.

[emmie]

i only noticed them as i washed the anti slip mats.

[woofgang]

enamel like a roasting tin?

[davebro]

Might not be enamel - which is a glassified coating onto metal. Probably acrylic/plastic.

[emmie]

could be dave. its just odd, never noticed before.

oh dear, going on that its not good.

[youngmafbog]

If it is cold I would suspect stone/resin which generally has an acrylic sheet to waterproof it. Its fairly think though so surprised it is bubbling.

I suspect the only option will be a new shower tray.

[emmie]

its a long tray, and was put in by builders, plumbers when they turned the bath into a shower only room

[davebro]

as long as it's not leaking & you cover the surface with an anti-slip mat, is it really a problem?

[emmie]

hope not, i can get it replaced i think, but its about 4 years or so old, so not sure why its bubbling -

[youngmafbog]

I did the same thing for my mum 10 years ago, I think you have been unlucky Emmie and its a fault in the manufacture. I dont think it is anything you have done although I have never seen this in all the trays I have installed for people. Probably a bit late to claim a return though.

If its on a ground floor then I'd be tempted to ignore it (but watch for cracking) but if on an upper floor water damage from leaking is more of a problem so I'd probably look to replace it.

[emmie]

I am on the second floor, its just little bubbles, no cracks have appeared so far as i can tell - i just thought it was an imprint from mats, but that obviously isn't the case.

maybe it has an allergy to the combination of cleaning materials, shower gels etc you use.

[emmie]

maybe, its a hard thing to clean, as i can't bend that much, so the mats have left a mark where they sit. i have used viakal to get the marks off, but its still like it

[emmie]

i would have noticed im sure before, don't use shower gels, only soap.

[sivam]

perhaps lift the mats between uses and let it all dry. Do they not get mouldy.

[emmie]

if they get a bit mouldy i replace them with new ones,

[emmie]

yes i should lift them but there is no where to put them except onthe base.

[emmie]

what would cause the base to bubble, would it be collected water?

Have you been anywhere near it when the vitriol flows about Gulliver or Diddlydo?
