Plug hole plug for shower?

[Rollerball]

For some time I've been getting an intermittent unpleasant smell in the bathroom - never could figure it out until today, and I'm now sure that it's coming from the plug hole in the shower.

The trouble is that the shower in the bathroom is used possibly once a year, if that (I normally use a shower in another room). No doubt the trap is drying out so letting smells from the sewer pipe drift back up.

I could put water in it on a regular basis, but I'm looking for a 'better' solution - is there such a thing as a plug for the plug hole in a shower?

The problem is that the plug hole is flush with the bottom of the shower floor (as all showers are) so you can't use a normal sink plug as there's no dip for it to sit in.

Is there a shower plug for the plug hole available on the market?

Can you pull out the grating? if so then wrap it in cling film and replace,
lable shower, to remind anybody that may try to use it,

why cant you just use the shower more often?

If you can access the waste then fit a HepVo valve after the trap, should stop the problem.

My local merchants refer to them as "Fanny" traps

That should read "F4nny"
