Blocking smell from unused shower drain

ThisIsWeird

The smell comes up through the tray's drain grill? In which case, just seal that hole.
Am I missing something?
Don't pour anything else down there - especially caustic stuff - as you know it leaks.
How are you currently sealing it with a bag? How can you wrap that around it? Or is it just flat?
If so, keep doing that. Do you have sili sealant? Run a bead around the circular top cover, cut a matching circle of the plastic, and stick it down.

Thanks everyone for taking the time to help me. The plumber suggested spraying a loan of expanding foam down to seal it completely, which makes sense 

Surely a tube of silicone sealant would be a cheaper option and will also seal it permanently.

Do you mean seal the tray? We're ripping out the bathroom soon to refurb whole place and have another (better) bathroom to use on a daily basis anyway.

No. Just seal the plug hole.

The smell actually seems to have (almost fullly) gone with just the piece of plastic bag taped over the drain. Thanks again everyone

This is an interesting dilemma as I have the same problem. We have a wet room as an extension in our bungalow when we bought it five years ago (one of the main reasons for buying as I am disabled) and, despite the shower being used three times a week, the smell from the drain is awful, (especially over summer) like rotting cabbage mixed with sewage!! We have poured down various disinfectants, domestos, plug hole unblocker, air freshener squirted down and had the hose pipe on full down the trap for 10 minutes at a time, all to no avail as the smell returns. We have checked the outside drains , blasted the hose down but nothing is blocked. I had heard that bungalow drains are obviously closer to the living areas with it being single storey but never expected smells like this. Any advice from
anyone would be amazing as I can’t live with this stench much longer, as the wet room is an en-suite and I can’t stand the smell (nose like a bloodhound) but hubby can’t smell it which is really frustrating!

I had this issue with a shower, turns out whoever installed it forgot to fit the trap part that left water in the drain to block the smell. A new shower drain solved the issue.

I used a piece of round silicon from the kitchen that was designed to help open jam jar lids- it worked well and was easy to move as the shower was in daily use.

Does not make sense to me, the smell will still come from where you have a leak in the pipework.
