Locking Vinyl in Showers?

[Brandon Roof]

Has anybody ever used locking vinyl plank or tile for tub or shower surrounds?  I recently saw a Durawall video where they applied adhesive to the back and silicone in all the locking joints.  Anybody have any firsthand experiences or have input as to whether or not this would be a reasonable idea?

In the nasty old days of C-class rentals we glued in sheets of rolled linoleum offcuts as tub surrounds. Amazingly they held up well, but we did coat the old drywall walls with with 'liquid rubber'. My concern with interlocking vinyl would be joint expansion consistent with Hot water hitting it but not equally. These joint sites would be prone to mold & water infiltration unless you painstakingly silicon every joint. Then again with uneven joint expansion/contraction due to hot water it may compromise the very thin silicon bond you talk off applying.  Last year (in a flip) we had professionally installed vinyl flooring glued to a perfectly good subfloor & because of a very hot humid summer it was a peeling/lifting in spots nightmare.

Definitely not something I would be prepared to experiment with but would be interested in following your progress.
