The WholeSeal Wetroom 800mm x 800mm x 90mm Square Shower Substrate with Square Waste Outlet helps you build a sleek, fully tiled wetroom that looks good and stays watertight. It's made from structural foam, giving you a strong, lightweight base to work from. It's a practical choice for both renovations and new builds, whether you're a confident DIYer or a professional installer.

It's the hidden foundation of a level-access shower, sitting under the tiles to give you a seamless floor. As a tray former, it creates a built-in fall to the waste, so water drains away quickly under a level, tiled finish. That means no lip or step, giving you a seamless, walk-in shower that's easy to use for everyone. It's waterproof, giving you real confidence in a wet area.

It measures 800mm x 800mm, with a thickness of 90mm. It's light enough to handle easily on site, which helps installation go smoothly. It's tileable, so you can finish it to match the rest of your bathroom.

It's designed to be plumbed in and then tiled over, keeping the process straightforward. It comes with a 15 year guarantee against manufacturing defects, giving you real peace of mind.
