Description
Create a permanent and maintenance free, one-way seal for 2" or 50mm floor and shower drains with the GS50 Grate Seal®.
The GS50 Grate Seal® is a specially designed rubber, one-way valve that is easily retro-fitted into 2" or 50mm floor and shower drains preventing sewer gases, airborne bacteria, soap suds, vermin and noise from making their way out of the drainage system into habitable areas.
As a WaterMark® approved product, the one way valve does not restrict flow, and the flow rates achieved more than cope with the maximum allowable flows from plumbing fixtures such as showers. Unlike other products on the market, a water seal is not required for Grate Seal® to be 100% effective making Grate Seal a permanent and maintenance free solution.
Grate Seal® is produced from an antimicrobial polymer compound making it durable and resistant to breaking down and allowing it to be used in a wide variety of applications, including the medical and commercial field. Grate Seal® is supplied at a low cost considering the problems that are resolved without having to remove or replace tiled surfaces.
- Unit is one piece and self cleansing.
- No ridges or braces to obstruct or catch waste.
- No fixing required as the seal stays in place through friction.

Simple concept and simple to install.
Installed two of these at home over the weekend. Unfortunately neither of the drains I was installing into were standard. One had been reduced by whoever installed it with mortar, so I had to get creative with the seal. The other drain had a 35mm pipe (weird) and I had a 50mm Seal unit. Again I got creative and used a coke plastic bottle lid, cut off to screw the oversized seal into place and create a fairly air tight seal, whilst still allowing the diaphragm to open and close.
Amazing product. Easy to install and works perfectly.
It really works well, there are no more smells.
Blocks off bad smells and odours associated with drains.
