Can I Install Cement Board Then Tile Over A Sheet Vinyl Flooring In A Bathroom
Need some advice and guidance regarding installing tile on the floor of a small 5' X 5' bathroom.
The floor currently has a single piece of good quality vinyl sheet flooring I installed about 15 years ago that is still in perfect condition with no cuts, lumps etc. When I installed it, I first screwed and glued a piece of sanded 1/4" or 5/16" plywood over the 5/8" tongue and groove sub floor so I had a good smooth surface for the install. The vinyl sheet floor was then glued to the plywood where it has remained.
So my first question is can I reliably install cement board over the sheet vinyl then install ceramic or porcelain tile on top of the cement board?
If so, will 1/4" thick cement board be adequate and what do I need to do to prepare the sheet vinyl floor before installing the cement board.
Would appreciate your comments and suggestions.
Thank you
Dom

If the bathroom is only 5x5, why not do it right and demo the existing floor and then you wont have to ask the question regarding reliability!

You guys just ruined my day.
How hard will it be to remove glued down sheet vinyl?
If I remove the sheet vinyl and 1/4" plywood, how thick will the new plywood need to be?
Is 1/4" thick cement board adequate on top of the new plywood?
Thanks for your input

3/4" plywood is the norm, if you have just 5/8" another 1/2" will be sufficient.
Others say 1/4" CBU is good for floors, personally I always use 1/2" and feel 1/4" would be better for countertops!

Thanks for your input everyone.
I decided to remove the vinyl and 1/4" plywood as one as was suggested. Although I couldn't remember whether I glued the plywood to the sub floor which I find today I didn't, instead I attached it with a million screws which made removal a pain but I'm getting there.
Once I get it all removed I'll be back for more advice.
