Description
Shower Floor Water Stop is a 12mm aluminium trim designed for installation at a shower floor threshold, where it forms a physical barrier to help keep water contained within the shower recess rather than spreading onto the surrounding bathroom floor. As with any threshold trim of this kind, correct integration with the waterproofing membrane and floor tiling either side of the threshold is essential to how well it actually performs on site.
Because Multifors does not currently publish a full technical or installation datasheet for this specific product, exact fixing method, compatible adhesives and detailed dimensional tolerances should be confirmed directly with Multifors or a tiling professional before specifying it for a particular job, rather than assumed from general threshold-trim practice.

Where to Use
- Shower floor thresholds
- Wet-area floor junctions requiring a physical water barrier
How to Apply
- Confirm the installation method — check with Multifors or your tiler for the specific fixing and sealing method for this profile.
- Integrate with waterproofing — ensure the water stop ties in correctly with the shower’s waterproofing membrane.
- Fix in place — install at the threshold per the confirmed method.
- Seal all joints — seal thoroughly at both ends and along the trim to prevent water bypassing the barrier.
Important Notes
- Confirm compatible adhesives, sealants and installation method with Multifors before starting the job.
- Correct integration with the surrounding waterproofing membrane is essential to how effectively the water stop performs.
A threshold water stop earns its place in a shower build even when the waterproofing membrane underneath is done correctly, because membranes manage moisture within the substrate while a physical stop manages water sitting on the surface at floor level — the two work together rather than one making the other redundant. Getting the detail right at this single junction point is disproportionately important to how a shower performs day to day, since it’s the one location in the room where water is guaranteed to be present in volume every time the shower is used.
Because this listing carries no published technical datasheet, treating it with the same caution as any unspecified building product is the safer approach — confirming installation method and compatible sealants directly with Multifors before the job starts avoids a costly rework if an assumption about fixing method turns out to be wrong once tiling is underway. That single confirmation step is a small cost against the risk of an incorrectly detailed threshold.
