Get this your cutting corners .if you tank a whole room it's waterproof .if you do what your saying it isn't. A wet room is a wet room. Doing half a job is what your suggesting
Tell me what you recommend is the better option .draw both scenarios in crayon .use a blue one to show where water goes in both options .my blue crayon goes down drain where does yours go
If it's got a tray just tile it .as the Silicon is only thing stopping water getting to walls etc .like the thousands of homes done each day by countless house builders .if you tank walls it only forces water down any way to floor you haven't tanked .what is the point
@Kevbos your posts are tantamount to trolling. You have made your point that you disagree with tanking in this scenario. Everyone has disagreed with you and the OP can digest all the information before them to make a decision. I don't think we need to hear from you again on this matter. Thank you for contributing though.
Alot of disagree s with my comment on what a wet room is .... A wet room is a wet room to be clear .A wet area is a wet area .there is a difference .learn your tech boys .tanking a wall onto a bath edge does not make it a wet room. Sort your little world of tiling minds out and sort it out .A wet room is a whole room tanked into a drain . Disagree all you like your wrong ... stop selling yourselves as something your not ...
