Does not allow water from shower base to pass through.
Hi Kyran,
Thank you for taking the time to review your purchase.
I see that you mention water draining from your shower base, however the product you are reviewing is our 40mm basin waste replacement silicone insert, which is sold strictly for installation in our stainless steel 40mm basin waste - designed for use in bathroom basins only.
Unfortunately, this replacement insert is not suitable for use in floor waste or shower waste outlets. The products designed for use in floor waste or shower waste outlets are models GS01 (100mm/80mm) and GS50 (50mm).
Please don't hesitate to get in touch if you would like to discuss in more detail or require further information.
Kindest regards,
Grate Seal Admin
