from 75 reviewsMy drains are 90mm at top so used the off cut to place around the 80mm and works fine.
Suggest you could advertise the fact.
Happy with the result for my 3 drains.

I was not sure how I was going to fix the odour problem from a ground floor shower drain, an odour that then permeates the whole downstairs apartment reno. It would have been a huge amount of work / expense to cut up 65 year old concrete floors to work out where pipes are running and what sort of trap could be installed. It took 10 minutes, once I stopped avoiding trying to find a simple solution, to find this product. It's perfect! It will actually slip over the lip on the new shower drain frame. I'll set the frame into the floor with a decent silicon, so if it ever needs replacing it will be a very simple case of slicing out some silicon and putting in a new one. Extremely happy I found this product.
Love the product, works a treat
I wish I had have known about this item years ago.
Well worth the cost, finally put a stop to the drain smell! 😷
Works as described. Easy to install.
Excellent seal which does not inhibit the flow of water but blocks nasty smells from drains and pipes from entering household rooms. Highly recommended for any property.
I was NOT disappointed with how effective these are. You have to install the device slowly as the measurements are so accurate if you rush it wont seal properly but only takes a couple of minutes to get it right and then is basically set and forget now. Thanks!
Blocks off bad smells and odours associated with drains.
My son recommended these and I am so pleased he did, not only have they stopped the septic smell that comes up in bathrooms when we get rain but they also seemed to have stopped our Crome plated outlets and floor drains going black……. I highly recommend these and have them in both our bathrooms.
So easy to install and smart delivery process
I’ve been putting up with smells from shower floor waste for years. Installed grate seal within a couple of minutes and solved the problem. Extremely happy with this solution.
Highly recommended!
Great product.
