Let customers speak for us
from 83 reviewsSo easy to install, and I'm not handy at all! Took less than 5 mins.
Completely effective, bad smells are massively reduced and no more drain flies!
Shower is draining perfectly, no issues since installing.
Brilliant invention!
I can’t believe how far across the globe i had to look find something so essential
Packed, and delivered fast. Very happy with this, fits perfectly. Stopped our trap smell issue. Would highly recommend. Thanks👍🏻
Easy to install, anyone can do it.
Amazing product. Easy to install and works perfectly.
Works great. fast shipping.
The Grate Seal 100mm-80mm is a wonderful product. They have solved problems for me prior to this, and success is on the horizon with the latest pair when I get a chance in the next day or so.
It really works well, there are no more smells.
My 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.
