Building a barrier free bathroom - AKW Tuff Form or Linear Shower Drain - which is the best option.
I have been building barrier free bathrooms for a number of years and of late focusing my installs on linear shower drains. Currently I have only built four barrier free bathrooms - three times with a simple point drain and topical waterproofing (Kerdi Drain). And once with a linear drain.
Working with the linear shower drains it is possible to use large format tile and one way slope. This does however pose it's own challenges in layout and grading prep. I have been debating this practice in great length over on my Linked In pages and wanted to get some insight from the Plumbers.
Have any of you men installed this ready made shower pan from AKW (AKW Tuff Form)? It looks straight forward and can be attached to the floor joist with simple screws. I can not find a cUPC clearance letter for it and wonder how you can flood test a pan like this.
In most of the online examples I notice that the floor is covered with lino or equivalent and not tile. I worry that the deflection of this base exceeds the L/720 requirement for large format tile.
Who has installed one? Have you seen one tiled?
