When it comes to public toilets and changing facilities, hygiene, durability and ease of maintenance are top priorities. One often-overlooked element that plays a key role in meeting these standards is the floor screed.
Whether you’re planning a new build or renovating an existing space, getting the screed right sets the foundation—literally—for a safe and long-lasting flooring solution.
Why Floor Screeding Matters in Public Facilities
Public toilets and changing areas are high-traffic environments, exposed daily to moisture, cleaning chemicals and constant use. A poorly prepared subfloor can lead to issues like uneven tiles, cracking, or even water damage—resulting in costly repairs and potential health and safety concerns.
Screeding ensures:
A level and stable base for tiles, vinyl, resin, or safety flooring.
Improved water resistance when used with the appropriate additives or membranes.
Enhanced durability under heavy footfall and cleaning routines.
Types of Screed Suitable for Wet Areas
When selecting screed for toilets and changing rooms, consider the following types:
Traditional Sand and Cement Screed: Cost-effective and widely used, but requires longer drying times. May need additional waterproofing.
Fast-Drying Screeds: Ideal for time-sensitive projects. These allow for quicker flooring installation and minimal disruption in high-use facilities.
Liquid (Flow) Screeds: Excellent for larger areas and self-levelling, which helps achieve a smooth finish with minimal labour. Not always ideal for sloped floors unless properly managed.
Polymer-Modified Screeds: Provide added flexibility and water resistance—helpful in damp or humid environments.
Key Considerations for Screeding Public Toilets
Drainage and Falls: Ensure correct gradients are built into the screed to guide water towards floor drains. This is essential for changing rooms with open showers or wet zones.
Slip Resistance: While the screed is hidden beneath the final flooring, it must support surfaces that offer high slip resistance—especially in areas prone to water or steam.
Hygiene Compliance: A properly levelled, moisture-tolerant base helps prevent pooling and bacterial build-up under the finished floor.
Durability Under Load: Choose a screed mix that can withstand foot traffic, occasional impact from equipment, and frequent cleaning with commercial products.
Summary
Floor screeding might not be the most visible part of a public toilet or changing facility, but it’s one of the most important. A well-screeded floor sets the groundwork for a clean, safe and professional environment that can withstand the demands of daily public use.
